Latest update (minor clarifications): 7 July 2023 Adapted from the Cairo coding style document Libdwarf/dwarfdump etc coding style. In "Tools that help" we provide a tool (dicheck) that enforces some parts of the coding style. Please don't submit changes (longer than a few lines) that cause messages from dicheck. This document is intended to be a short description of the preferred coding style for the libdwarf and related source code. Good style requires good taste, which means this can't all be reduced to automated rules, and there are exceptions. We want the code to be easy to understand and maintain, and consistent style plays an important part in that, even if some of the specific details seem trivial. If nothing else, this document gives a place to put consistent answers for issues that would otherwise be arbitrary. We avoid using features of C standardised after ANSI C89,ISO C90. Most of the guidelines here are demonstrated by examples, (which means this document is quicker to read than it might appear given its length). Most of the examples are positive examples that you should imitate. The few negative examples are clearly marked with a comment of /* Yuck! */. Please don't submit code for libdwarf that looks like any Yuck! Section list: Tab characters Braces Whitespace Struct Format and Content Managing nested blocks Test or Loop with Side Effect Switch statements Singly Linked Lists Macro Tests Commented Lookup Tables Memory allocation Naming, namespace Checking For Overflow Dwarfdump Flags Data Never use strcpy strcat strncpy Static data and functions Argument Lists Tools that help ### Indentation Each new level is indented 4 more spaces than the previous level, and an if is followed by a space and a left-parenthesis: if (condition) { do_something(); } Done solely with space characters. Similarly, for is to have a single space after the r followed by a left parenthesis. for (v; condition; v2) { do_something(); } ### Tab characters The tab character must never appear except in a printf string. ### Braces Most of the code in libdwarf uses bracing in the style of K&R: if (condition) { do_this(); do_that(); } else { do_the_other(); } and that is the preferred style. Even if all of the substatements of an if statement are single statements, the optional braces must always appear. if (condition) { do_this(); } else { do_that(); } Never if (condition) /* Yuck */ do_this(); /* Yuck */ else /* Yuck */ do_the_other(); /* Yuck */ Note that this last example also shows a situation in which the opening brace can be on its own line, though usually it looks like this example. The following can be difficult to read. if (condition && other_condition && yet_another) { /* But we usually do put the brace here */ do_something(); } ### Whitespace Separate logically distinct chunks with a single newline. This obviously applies between functions, but also applies within a function or block and can even be used to good effect within a structure definition. But don't get carried away with blank lines: struct _Dwarf_Data_s { struct Something_s op; double tolerance; Dwarf_Unsigned line_width; Dwarf_Unsigned line_height; Dwarf_Unsigned line_thickness; /* Notice the _s on struct declarations And notice indent of this comment and the blank line above this comment to make it clear the comment applies to fill_rule. */ struct Reg_Struct_s fill_rule; Dwarf_Signed distance_from_end; ... }; Having both CamelCase in names and _ in the names used by the library is perhaps unusual, but it's been that way in the libdwarf source since the library was first written. So we stick with it in most cases. Never use a space before a function-call left parenthesis or a macro-call left parenthesis. Don't remove newlines just because things would still fit on one line if removal breaks the expected visual structure of the code. Eliminate trailing whitespace on any line. Also, avoid putting initial or final blank lines into any file, and never use multiple blank lines instead of a single blank line. The trimtrailing program in the libdwarf-dicheck project will fix such issues. Use dicheck tools below to find trailing whitespace and indentation inconsistencies. You might find the git-stripspace utility helpful which acts as a filter to remove trailing whitespace as well as initial, final, and duplicate blank lines. As a special case of the bracing and whitespace guidelines, function definitions in libdwarf should always take the following form: int my_function (Dwarf_Debug dbg, Dwarf_Unsigned second_arg, Dwarf_Unsigned* ret_value; Dwarf_Error *error) { do_my_things(); /* The meaning of life */ *ret_value = 42; return DW_DLV_OK; } In dwarfdump, the code tends to follow this form too (but not always). Function prototypes inside libdwarf headers (as opposed to .c files) usually have the return type (and associated specifiers and qualifiers) the same line as the function name. If the line gets long additional lines are appropriate. In .c files the function name starts a line as shown above. Notice, above, how a too-long argument line gets folded with standard indentation(4). Break up long lines (> 70 characters) and use whitespace to align things nicely indenting by four spaces. For example the arguments in a long list to a function call should all (but the first) be aligned with each other: align_function_arguments (argument_the_first, argument_the_second, argument_the_third); And as a special rule, in a function prototype, (as well as in the definition), whitespace should be inserted between the parameter types and names so that the names are aligned: void align_parameter_names_in_prototypes(const char *char_star_arg, int int_arg, double *double_star_arg, double double_arg); Parameters with a * prefix are aligned one character to the left so that the actual names are aligned. ### Struct Format and Content Usually, avoid adding a comment alongside declarations unless it is a very short comment. The following example uses meaningless x y z field names (sorry), but but does show a short prefix related to the struct name. Generally struct members should have a prefix common to that struct and hopefully distinct from other struct declarations. This short prefix makes it much easier to find all uses of a particular field in the code (with grep). struct Dwarf_Nothing_Special_s { int ns_x; /* usually avoid comment here this is Yuck! and this is even worse as continuation. Yuck! */ /* Comment here about ns_y with blank line above and below to make it clear which line referred to. */ unsigned ns_y; unsigned ns_z; }; ### Managing nested blocks Long blocks that are deeply nested make the code very hard to read. Fortunately such blocks often indicate logically distinct chunks of functionality that are begging to be split into their own functions. Please listen to the blocks when they beg. You will notice many exceptions to this in the code, unfortunately. In other cases, gratuitous nesting comes about because the primary functionality gets buried in a nested block rather than living at the primary level where it belongs. Consider the following: foo = malloc (sizeof (foo_t)); if (foo) { /* Yuck! The error return becomes hard to see. */ ... /* lots of code to initialize foo */ ... return DW_DLV_OK; } _dwarf_error(dbg,error,DW_DLE_MALLOC_RETURNS_NULL); return DW_DLV_ERROR; This kind of gratuitous nesting can be avoided by following a pattern of handling exceptional cases early and returning: foo = malloc (sizeof (foo_t)); /* A test foo == NULL is fine but the following is better as there is no danger of turning == into = by accident. */ if (!foo) { _dwarf_error(dbg,error,DW_DLE_MALLOC_RETURNS_NULL); return DW_DLV_ERROR; } ... lots of code to initialize foo */ return DW_DLV_OK; In otherwords, refactor deeply nested code. There are places in the library and dwarfdump where appropriate refactoring has not yet been done. The return statement is often the best thing to use in a pattern like this. If it's not available due to additional nesting above which require some cleanup after the current block, then consider splitting the current block into a new function before using goto. ### Test or Loop with Side Effect Never do: if ((foo = malloc (sizeof (foo_t)))) { or if (foo = malloc (sizeof (foo_t))) { as the reader has to think carefully about it, whereas foo = malloc (sizeof (foo_t)); if (foo) { is more transparent (in some sense) and makes it easier to stop( in debugger) or add a printf in case this is a point where things might be going wrong somehow. Note the space between if and the left parenthesis. Also see "Managing nested blocks" just above. ### Switch statements We use the following indent practice: switch(x) { case a: { /* Define&use local variables, do something */ } case b: /* Do something, no new local variable needed. */ break; ... default: /* do something or break*/ } The default case is used everywhere (instead of being omitted when it could be omitted) to satisfy a Cobra rule. One thinks consistency reads well. dwarf_names.c (for example) is full of functions where all known values do a return on each case: and there the last entry is default: break; followed outside the switch by the return for the error case. ### Singly Linked Lists Many places in libdwarf build singly-linked lists. And do it without a check for NULL. Stephen Macguire, in Writing Solid Code (Microsoft Press, 1993) explains how and why one should do this on page 126. We assume it's well known. The same book's "Candy Machine Interfaces" chapter lead to the design of the return values used in the library. ### Macro Tests Commented #ifdef SOME_MACRO #else /* !SOME_MACRO */ #endif /* !SOME_MACRO */ #ifdef OTHER_MACRO #endif /* OTHER_MACRO */ The comments add clarity when one is not familiar with code in the area but are not required if the #else #endif are within a couple lines of the #if(def). In a spot with nested #if(def) the comments become necessary to avoid confusing the reader. There is nothing wrong with adding them everywhere. ### Lookup Tables Any situation requiring a lookup table should use one or the other tsearch functions. The practical ones are dwarf\_tsearchhash.c and dwarf\_tsearchbal.c. dwarfdump and libdwarf each use one of them and only one of them. See the tsearch-code project to see the full set available. These use the traditional UNIX tsearch arguments and return values even though those are not good designs by current standards. Expanded to have destroy() functions whose prototype was copied from GNU man pages. GNU libc has much nicer (in the sense of much nicer interface designs) non-standard tsearch functions, but we've ignored those to keep to the official Single Unix Specification standard interfaces. ### Memory allocation In general, be wary of performing any arithmetic operations in an argument to malloc. You should explicitly check for integer overflow yourself in any more complex situations. In libdwarf most allocations use \_dwarf\_alloc() instead of malloc. And the tables of valid types (which are predefined in libdwarf) allow for constructor/destructor functions. The \_dwarf\_alloc() code keeps a record of what is allocated so a careless user can simply call dwarf\_finish() at the end and all the allocated data will be freed that was not already freed via user calls to dwarf\_dealloc(). ### Naming, namespace Avoid conflicting with other libraries or with user code. Anything publicly visible in headers or in the library (.a or .so or .dll) must have only certain prefixes to names visible in dwarf.h or libdwarf.h or a library a user links in (.a or .so or .dll). Prefixes are: DW_ (this is from the DWARF Standard and dwarf.h) Dwarf_ (for types) dwarf_ (for functions) _dwarf_ (for non-static functions in the library but not for user code to call, so far this has worked acceptably). For a .so or .dll current builds (meaning September 2021 and later) ensure such names are invisible to callers. dw_ For public function argument names. dwarf.h and libdwarf.h functions must have all arguments named with a leading dw\_ so that doxygen has names to work with and to make the function prototypes more readable. Ensure new functions or changes are reflected in the libdwarf.h doxygen comments. Function names should be all lower-case and should use underbar(s) for readability. Function-local variables should be lower-case with underbars for readability. It's ok for a small loop with counters to use single letter names like i or k or m. structure members should have a struct-specific 2-character prefix to the name (followed by an underbar). This convention makes it much easier to grep for uses of members. ### Checking For Overflow Libdwarf and dwarfdump are often dealing with offsets and indexes read from disk object files and all such should be checked before use. That approach means that dwarfdump (and libdwarf callers in general) need not check the things that libdwarf has returned (at least those libdwarf could check). When it is possible that X +Y might overflow make every effort to check X an Y independently before attempting an addition. If you are confident X and Y are sensible (given available data like section sizes) you can add them and then determine if the sum (say an offset) is still within the relevant section or data-item usable range. There are many libdwarf-internal functions to read data from an object, and all of them require an end-pointer argument so the code can easily check for corrupt object-file or DWARF values without duplicating the error-code-setting. ### Dwarfdump Flags Data Dwarfdump has a large number of options and nearly all the option values are recorded as fields in a single global structure glflags (see dwarfdump.c). Option data not in that structure should be moved into it, in general. This makes it much simpler to find instances using flags and to know, reading dwarfdump source, when flags are being referred to.. The text in this document (not the examples!) was formatted with the vi command "!}fmt -64"...without the quotes. ### Never use strcpy strcat strncpy dwarfdump has dd\_safe\_strcpy(). libdwarf has \_dwarf\_safe\_strcpy(). These functions eliminate the need for the three traditional string functions strcpy, strcat, strncpy and do exactly what is needed safely while doing nothing extra. ### Static data and functions Any data or function not referenced outside the defining source file should be declared 'static'. In the libdwarf library itself static data is not appropriate except for data which is also const. Multiple Dwarf_Debug may be open at the same time in a single program (dwarfdump or user code) so static data will eventually be a bug. ### Argument Lists Beginning February 2023 we are moving to presenting argument lists with no space between any pointer * and the immediately following argument name. And with such lists mostly lining up the names (with the first argument usually not lined up with anything). functionname(Dwarf_Debug x, Dwarf_Off *out_value, Dwarf_Error *error) This format is suggested, not required. ### Tools that help The github.com/davea42/libdwarf-dicheck project is a tool that checks indentation and a few other things to find instances of failures to follow codingstyle rules. The program trimtrailing in that project removes trailing whitespace and changes a sequence of blank lines to a single blank line. The open-source project github.com/nimble-code/Cobra package is being used (beginning December 2021) as an aid to finding problematic or not-best-practices code. It does not compile anything, it does checking via source scans with regular expressions. Not everything it mentions is necessarily a bug or a defect. The primary commands used (in a source directory) are cobra -f basic *.h cobra -f basic *.c cobra -terse -f stats *.[ch] cobra -terse -f metrics *.[ch] # The cwe command generates lots of spurious output as they # check things we do not care much about. # But some of it has been useful. cwe *.h cwe *.c libdwarf-code-0.11.1/CONTRIBUTING.md000066400000000000000000000045261472336503500165440ustar00rootroot00000000000000Thank you for considering contributing to libdwarf development or documentation! Any and all email mentions here mean send to libdwarf -at- linuxmail -dot- org. ## Testing Contributions should provide open-source (small) test cases and instructions to prove the change is correct, or should mention what existing tests show correctness, or should explain how to test the change. It's not necessary to actually modify libdwarf-regressiontests, but documenting (in some way) how this change can be tested is important. ## Formalities If your contribution is just a few lines there is no paperwork to deal with. Generate a github pull request or generate a git diff and email it. If your intended contribution is more than a few lines and someone in your organization/company has already established a relationship with the project there is no paperwork needed. Email to enquire if you are already covered (name the relevant company/organization you are working for). Otherwise there is a simple form to fill out and sign (email a pdf of the signed document). Either https://www.prevanders.net/generic_takebacklite.txt or https://www.prevanders.net/special_takebacklite.txt will do. We will sign to and return via email a copy with all signatures. It is intended to assure the project that you have the right to contribute your code, that it's not code owned by anyone else. These forms were prepared by SGI / SUN (respectively) company lawyers 20+ years ago, not by the library authors ourselves.... If you are thinking of making a contribution of more than a few lines drop an email and describe what you have in mind. The file CODINGSTYLE.md describes the coding style in the project. Formatting is simple and the basic rule is 4 character indents and no tabs. All contributions should be correct for all the supported platforms (Linux (all), MacOS, and Windows Msys2) and supported endianness. That's nearly always trivial and needs no special effort. ## Tools for formatting A simple C++ tool is in the project libdwarf-dicheck containing the dicheck and trimtrailing program source. Compile the two protrams and run dicheck on any source file you change and fix any warnings (the trimtrailing C++ program will remove trailing whitespace for you.). ## Python Formatting All python code in the project is formatted with the python3-standard formatter ```black``` libdwarf-code-0.11.1/COPYING000066400000000000000000000016271472336503500153450ustar00rootroot00000000000000 COPYING August 6 2023 The source code in the libdwarf directory is LGPL version 2.1.

Some errors (not affecting correctness, thankfully) were present. Removing a now-unused argument from _dwarf_next_cu_header_internal() and refinement of the test for entry_pc with if (entry_pc_attrnum >= 0 && cucon->cc_producer == CC_PROD_Apple) And rearrangement of the DW_AT_low_pc vs DW_AT_entry_pc (Apple only) checks modified: src/lib/libdwarf/dwarf_die_deliv.c Mainly debug printouts and preparation for a validity check of data read from a DWARF section. modified: src/lib/libdwarf/dwarf_loclists.c Added CC_PROD_Apple for sharpened handling of DW_AT_entry_pc. And new internal function _dwarf_entrypc() modified: src/lib/libdwarf/dwarf_opaque.h Refactoring Now dwarf_lowpc() and the new _dwarf_entrypc() use the same implementation code. modified: src/lib/libdwarf/dwarf_query.c Lots of ifdefed-out debug printf (to be removed pretty soon) and crucial correction of _dwarf_determine_die_range_offset() to get 'base address' correct. Leaving a superflous argument in dwarf_get_ranges_baseaddress() as the function is public. And corrected its code returning CU base address. Added (void)have_die_ranges_offset; /* FIXME */ to avoid compiler issues. modified: src/lib/libdwarf/dwarf_ranges.c Some #if 0 code will be deleted very soon. modified: src/lib/libdwarf/dwarf_rnglists.c Ill advised code in _dwarf_loop_reading_debug_info_for_cu() is now #if 0 out. To be deleted very soon. modified: src/lib/libdwarf/dwarf_tied.c Fixed dummy _dwarf_next_cu_header_internal() to reflect the revised internal function prototype. modified: test/test_dwarf_tied.c 2024-11-07: David Anderson commit ca4ee1438d54c31dcccb5dcec1ff13ba930c133f corrected a comment modified: src/lib/libdwarf/dwarf_rnglists.h 2024-11-07: David Anderson commit ee38cd9b8490d1ca6ca8dcd0e56d7df384360dd4 Corrected a comment and added a 1-line comment. modified: src/lib/libdwarf/dwarf_loc.c 2024-11-07: David Anderson commit 5a5426e2642d51cd2a647b1ad251f02a54a70d2c Reformatted the call arguments calling dwarf_get_ranges_baseaddress() Added a comment. modified: src/bin/dwarfdump/print_die.c 2024-11-07: David Anderson commit 9d3224578dcf9c0560c92f1f7c2136280fb3bdee October->November in the heading. modified: bugxml/dwarfbug.html modified: bugxml/dwarfbuglohi.html 2024-11-03: David Anderson commit 62be899578e664f90455f00bffb8e70263d6c8a5 Report better on what cmake finds about libz zstd modified: CMakeLists.txt 2024-11-03: David Anderson commit 754d5627c2d2d6f48a7e444fa5173ef447ae0c07 copyright modified: src/lib/libdwarf/libdwarf.h 2024-10-29: David Anderson commit 852d30d733099c2c914c0715c0d28a5abb409942 October modified: bugxml/dwarfbuglohi.html 2024-10-29: David Anderson commit 4d8560204d189555d021a4bc659d6065692346bf October modified: bugxml/dwarfbug.html 2024-10-21: David Anderson commit 1bedfea64dd349d1638cc0b75ddfa4876b0bce9c Small static function both_strings_nonempty() avoids compiler warning 2024-09-28: David Anderson commit c658d71f036e082ecf0bcfff6613ea24560ad429 Further refinement of heuristic, distinguishing 32bit from 64 bit PE objects in the check. modified: dwarf_peread.c 2024-09-23: David Anderson commit a095d0db09700bc82411ff776e67a22dbded78e6 Fix violations of codingstyle: line length, trailing spaces, indent, if( etc. modified: libdwarf/dwarf_debugnames.c modified: libdwarf/dwarf_harmless.c modified: libdwarf/dwarf_line.c modified: libdwarf/dwarf_loc.c modified: libdwarf/dwarf_rnglists.c modified: libdwarf/dwarf_tsearchhash.c 2024-09-23: David Anderson commit a1ef665e1d2c21fd2555699dea1f442f23fcbfd3 Another set of violations of codingstandard: trailing whitespace, indent, and line length. modified: src/bin/attr_form/attr_form_build.c modified: src/bin/dwarfdump/print_debug_names.c modified: src/bin/gennames/gennames.c modified: src/bin/tag_attr/tag_attr.c modified: src/bin/tag_tree/tag_tree.c 2024-09-23: David Anderson commit aa21630b4b119dfdeaf6585cd2353238506293cc Fix violations of the codingstandard: removing trailing whitespace, fixing indents and the like. modified: src/bin/dwarfdump/dd_attr_form.c modified: src/bin/dwarfdump/dd_attr_form.h modified: src/bin/dwarfdump/dwarfdump.c modified: src/bin/dwarfdump/print_debug_names.c modified: src/bin/dwarfdump/print_die.c modified: src/bin/dwarfdump/print_tag_attributes_usage.c 2024-09-19: Keith W.

All these changes are in dwarfdump, none in libdwarf. The old approach of generating statistics left out things about non-standard TAGs and ATtributes as it would have been extra work at the time. Now, using dwarf_tsearch and building searchable and sortable data, additional targeted reports become easy to add and update. No doubt more will be added. 2024-09-10: David Anderson commit 721d3d824976a80ce2c7128e2a123a11d5217ed0 Removed debug printf modified: dd_attr_form.c modified: print_tag_attributes_usage.c 2024-09-10: David Anderson commit e175de85d37df08c5b7791a1b5b2636228b7ad44 Now with more statistics from -ku modified: src/bin/dwarfdump/dd_attr_form.c modified: src/bin/dwarfdump/dwarfdump-ta-table.h modified: src/bin/dwarfdump/print_tag_attributes_usage.c Corrected an accidental omission. modified: src/bin/tag_attr/tag_attr.list 2024-09-10: David Anderson commit f2c1cb8269bdc225ef720d16a73fd15ee63998a7 DO NOT USE THIS COMMIT Now with the beginnings working (of the new records of usages) modified: src/bin/dwarfdump/dd_attr_form.c modified: src/bin/dwarfdump/dd_attr_form.h modified: src/bin/dwarfdump/print_tag_attributes_usage.c Fixed an old bug in this file: DW_TAG_subprogram listed as a row twice. modified: src/bin/tag_tree/tag_tree.list 2024-09-10: David Anderson commit 01266626c48005afb15467da74f6bb0d0488982a DO NOT USE THIS COMMIT.

We altered the (internal) struct Dwarf_Debug_s with better naming for loclists rnglists fields merged from a skeleton to the dwp/dwo. We revised DW_DLV_ERROR reports to always use the main-object, not the tied-object (if any) to report errors. Simpler and saver now we read more from the tied-object. Made possible by 3 new fields in dwarf_opaque.h (a libdwarf-private header).

This bug has been present in the library for many years. modified: src/lib/libdwarf/dwarf_form.c 2024-02-11: Jeremy commit 520e20185262f96c9580cab157307b0890fc2c66 Make note of DW_AT_call_file in dwarf_srcfiles 2024-02-09: David Anderson commit 6f960447511a3866960cbc14681462f6db75e4b4 In case of memory exhaustion ensure that allocations going out of scope are freed. modified: src/bin/dwarfdump/print_abbrevs.c Instead of a = b use a = std::move(b) where transfer of ownership is going on.

Fixed a bug which would result in a compile failure referencing includes for libz.h and zstd.h if one had neither. Doing set10('LIBZ_H',false) in meson has the wrong effect, as LIBZ_H gets defined 0 so #ifdef LIBZ_H finds LIBZ_H is defined. modified: meson.build modified: meson_options.txt modified: src/lib/libdwarf/meson.build 2024-01-20: David Anderson commit 20e6efcbde6ba8fd964cde62c0e4c5b3ee3088b9 ifdefs for zstd.h and zlib.h were written in a non-obvious way.

There is something odd in the declaration of posix read() and lseek() in VS community edition 2022. The warnings complain of off_t to 'unsigned long' and size_t to 'unsigned int' which seems to make no sense.. Linux and posix docs agree on the argument and return types and the variables are appropriately typed. 2024-01-09: David Anderson commit 13cf9ff0ec8593e5bf494c4e33fd0da6b4727888 Now we can read DWARF2 produced by an obsolete compiler from Metrowerks. It uses DW_FORM_ref_addr where it means DW_FORM_addr (DW_AT_low_pc for example). It sets the relocation section type to SHT_RELA correctly and then names the section with .rel (not .rela as it should). It has two .rel.debug_line sections for no reason. libdwarf checks the CU die DW_AT_producer string and notes when a CU was produced by the Metrowerks compiler, recording that internally for use in dealing with attributes and FORMs. modified: src/lib/libdwarf/dwarf_die_deliv.c modified: src/lib/libdwarf/dwarf_elf_load_headers.c modified: src/lib/libdwarf/dwarf_elfread.c modified: src/lib/libdwarf/dwarf_form.c modified: src/lib/libdwarf/dwarf_init_finish.c modified: src/lib/libdwarf/dwarf_loclists.c modified: src/lib/libdwarf/dwarf_opaque.h 2024-01-08: David Anderson commit 71a912250c33bab0179cae60b88bfc9d5457ffb7 Latest DW_LANG names now present. modified: src/lib/libdwarf/dwarf_names.c 2024-01-06: David Anderson commit 60c15ba27c5693193b4c9cd7ef02cca7a05693ed Moved some 2021 changes from 2022 to 2021 modified: ChangeLog2021 modified: ChangeLog2022 2024-01-06: David Anderson commit 560449faedd9c9ce543d1757ae20486a707923a9 Added new DW_LANG codes (see dwarfstd.org) modified: dwarf.h 2024-01-03: David Anderson commit cae2c6ae5363f050f65c7206b308412eed603b28 Merge: 146fa5e7 871cbd9b Merge branch 'AlexDenisov-alexdenisov/add-an-option-to-disable-zlib-zstd' Adding cmake option to avoid looking for compression libraries 2024-01-03: David Anderson commit 871cbd9b832d9a50796767a59590dbe948bcdf20 Merge: 146fa5e7 5f310464 Merge branch 'alexdenisov/add-an-option-to-disable-zlib-zstd' of https://github.com/AlexDenisov/libdwarf-code into AlexDenisov-alexdenisov/add-an-option-to-disable-zlib-zstd Adding option to cmake.

Revised the settings so PACKAGE_VERSION winds up in string quotes in config.h. * config.h.in.cmake: Revisions so PACKAGE_VERSION winds up in string quotes in config.h. 2019-10-21 David Anderson * configure.ac : Added additional AC_CHECK_HEADERS. Version 20191021 * config.h.in, configure: Regenerated 2019-10-18 David Anderson * CMakeLists.txt: Code the isBigEndian test correctly. * config.h.in.cmake: Code the #cmakedefine for WORDS_BIGENDIAN 2019-10-16 David Anderson * configure.ac: The use of AC_C_BIGENDIAN was incorrect and a revised use works properly so config.h has WORDS_BIGENDIAN when it should. * configure: regenerated. * config.h.in: regenerated. 2019-10-14 David Anderson * CMakeLists.txt: Corrected the cmake version of a couple tests so they work. * configure.ac: Now version 20191014. * configure: Regenerated. 2019-10-02 David Anderson * README.cmake: Updated and improved the comments about ctest. ctest now tests that dwarfdump and libdwarf basically work (as well as testing internal interfaces). 2019-10-02 David Anderson * configure.ac: Now version 20191002 * configure: regenerated. Version 20191002 2019-10-01 David Anderson * configure.ac: Now version 20190929 * configure: regenerated. Version 20190929 2019-09-19 David Anderson * configure.ac: Now version 20190919 * configure: regenerated. Version 20190919 2019-07-05 David Anderson * dwarf_elf_load_headers.c(read_gs_section_group): The check for an invalid gh_entsize of an SHT_GROUP secion was done too late. Now the check is before using the value (avoiding a divide-by-zero error). 2019-06-04 David Anderson * CMakeLists.txt,config.h.in.cmake,configure.ac: No longer reference inttypes.h or HAVE_INTTYPES_H as we do not refer to anything in that C99 include file. * configure: regenerated. Version 20190604 2019-05-29 David Anderson * CMakeLists.txt, configure.ac: Version 20190529 * configure: regenerated. 2019-05-24 David Anderson * CMakeLists.txt: Ensure there is a reasonable definition of uintptr_t even if stdint.h missing. * Makefile.am:Add config.h.in.cmake to the list of files. * Makefile.in:Regenerate * config.h.in: Add HAVE_INTPTR_T and intptr_t. * config.h.in.cmake: Add the 1 to several HAV_* config variables that lacked it. * Add PACKAGE_NAME etc via cmakedefine. * configure.ac: Add AC_TYPE_INTPTR_T, add comments about the *INTPTR_T stuff. * configure: Regenerated. * scripts/buildandreleasetest.sh. Add --nodwarfgen option to enable building with no stdint.h (c++ finds the #define of uintptr_t useless). 2019-05-22 David Anderson * CMakeLists.txt: check_include_file( "sys/elf_386.h" and check_include_file( "stdint.h" both had badly spelled (erronous) target variables. 2019-05-21 David Anderson * CmakeLlists.txt: The generator expression was unnecessary and is no longer used, instead a simple list variable is named DW_FWALL. 2019-05-20 David Anderson * CmakeLlists.txt: Now generates config.h at top binary level. * config.h.in.cmake: New, now the only config.h.in present 2019-05-20 David Anderson * CmakeLists.txt: The checks for elf64_getehdr and elf64_getshdr were written incorrectly. The library options changed to be consistent with standard practice: nonshared->BUILD_NON_SHARED shared->BUILD_SHARED wall->WALL (and the option generator expression corrected) nonstandardprintf->HAVE_NONSTANDARD_PRINTF_64_FORMAT HAVE_CUSTOM_LIBELF (new, not of general interest) dodwarfexample->BUILD_DWARFEXAMPLE dodwarfgen->BUILD_DWARFGEN test->DO_TESTING Version 20190520 * README.cmake: updated to match the new option names, * appveyor.yml: Updated to match cmake new option names. * config.h.in: Adding HAVE_CUSTOM_LIBELF line. * configure.ac: Typo correction and addition of --enable-havecustomlibelf Version 20190520 * scripts/buildandreleasetest.sh. Now reflects the new cmake option names, such as dodwarfgen=ON becoming DWARFGEN=ON. 2019-05-13 David Anderson * CmakeLists.txt: Now -Dwall=ON adds -Werror and reports the warning/error options. * configure.ac: Now version 20190513. --enable-wall now adds -Werror so warnings are considered errors by gcc. * configure: regenerated. * scripts/buildandreleasetest.sh: Now does a full compile with WORDS_BIGENDIAN forced on. Since most testing is little-endian this forces a compile testing that the code actually builds with WORDS_BIGENDIAN 1. 2019-05-07 David Anderson * CMakeLists.txt: Added comment on how the find_package() command works. See cmake documentation. * cmake/FindLibElf.cmake: Added comment mentioning how and where this is referenced. 2019-05-07 David Anderson * CMakeLists.txt: Added CXX to the project languages so dwarfgen will build with cmake. Version 20190507. * Makefile.am: Removed a file name: not needed. * configure: regenerated * configure.ac: Version 20190507 2019-05-05 David Anderson * Makefile.am, dwarfdump/Makefile.am, dwarfexample/Makefile.am, dwarfgen/Makefile.am: cmake and configure needed to agree on the list of files. Specifically configure.ac etc lists just cmake files that exist so it can generate a complete release, while CmakeLists.txt etc will not currently generate a complete release. Regenerated configure.in. 2019-05-05 David Anderson * configure.ac,configure.cmake: Version 20190505 * configure: regenerated 2019-05-02 David Anderson * scripts/buildstandardsource.sh: cmake has serious trouble with semicolons so now this copies the base libdwarf.h.in to generated_libdwarf.in while changing struct Elf to struct _Elf. cmake can do a simple copy. * configure.cmake: Now just copies the right file with Elf or _Elf to libdwarf.h. * scripts/buildstandardsource.sh: Now creates generated_libdwarf.h.in from libdwarf.h.in. using sed. Run by developer, not library users. * scripts/fixlibdwarfelf.sh Now just copies the right file with Elf or _Elf to libdwarf.h (used by configure, not cmake). 2019-05-02 David Anderson * Makefile.in: regenerated. 2019-05-01 David Anderson * CMakeLists.txt: Sets language C * cmake/AutoconfHelper.cmake: deleted, nothing here used any more. * cmake/FindLibElf.cmake: Now does C source test, not c++. * configure.cmake: moved the cmake macro includes to the first lines in the file. Added a JUST_LIBELF variable to correctly test for off64_t Does checking/setting for essentially all the needed HAVE_ etc variables. 2019-05-01 David Anderson * README.cmake: Made more complete. * configure.cmake: Even more setup here. 2019-05-01 David Anderson * CMakeLists.txt: Corrected a mistake in reporting install prefix. * cmake/AutoconfHelper.cmake: Removed unused functions, and for some functions changed to native cmake in configure.cmake. * configure.cmake: Now does a lot more setup here and using cmake (replacing some autoconf-like functions) And this now sets many things for each build directory, reducing the size of */configure.cmake files. 2019-04-30 David Anderson * README.cmake: New, describes use of cmake. * cmake/LibdwarfMacros.cmake: Added a final newline charcter as such is expected. * configure.cmake: Added testing lines. 2019-04-26 David Anderson * README.cmake. New. Describes cmake use and options. * CMakeLists.txt,cmake/FindLibElf.cmake,configure.cmake: Revised to be closer to configure as to what it does. 2019-04-25 David Anderson * configure.ac: Version 20190425. Updated to recognize recent changes. And some #include/define updates for Windows. 2019-04-22 David Anderson * configure.ac: Version 20190422. Now tests for stdint.h and inttypes.h. Uses AC_TYPE_UINTPTR_T so we can avoid a lot of warnings in 32bit and mingw builds. 2019-04-21 David Anderson * configure.ac: Version 20190421. Now --enable-nonstandardprintf (build with some non-standard printf formats allowed) adds -Wno-pedantic-ms-format so gcc will not warn about the non-standard formats. Only affects mingw. Otherwise the -Wno-pedantic-ms-format option (which nothing but mingw has) gets dropped. 2019-04-19 David Anderson * NEWS: Now --disable-libelf just disables linking with libelf. Elf files are read (libdwarf) and printf(dwarfdump). As always. The Elf reader detects corrupted Elf early on. 2019-02-24 David Anderson * configure.ac. Version 20190223. With --disable-libelf most header checking is unnecessary and suppressed. All the checks for int32 and the like removed as we no longer use such types. 2019-02-18 David Anderson * configure.ac: One can build forcing a non-elf build with --disable-libelf . If libelf is missing or will not compile the disable is automatic. Now zlib is separated so -lz is added to the link line with or without libelf. Version is 20190217 * configure.cmake: Now always defines DWARF_WITH_LIBELF so cmake builds continue to work as always. 2019-02-07 David Anderson * configure.ac. Version 20190201. Now allows lack of elf.h libelf.h and if those and zlib.h missing then the link line shows neither -lelf nor -lz (libdwarf and dwarfdump will then support PE and mach-o objects but not elf) 2019-01-15 David Anderson * configure.ac: Version 20190112 2019-01-10 David Anderson * configure.ac: Version 20190110 2019-01-09 David Anderson * configure.ac: Version 20190108 2019-01-05 David Anderson * configure.ac: Version 20190104 2019-01-02 David Anderson * ChangeLog: renamed ChangeLog2018 * configure.ac: Version 20190102 * Makefile.am: Now includes the tsearch files in the dist. libdwarf-code-0.11.1/ChangeLog2020000066400000000000000000000110511472336503500163600ustar00rootroot000000000000002020-12-26 David Anderson * scripts/find_pdfpages.py, scripts/rebuildpdf.sh: These rearrange pdf content so libdwarf2.1.mm reads in a more normal order (table of contents before content). 2020-12-23 David Anderson * configure.ac: Now version 20201223. * configure: Regenerated. * scripts/buildstandardsource.sh: Added a clarifying comment. * scripts/ddbuild.sh: Now builds the sourcefile opstabcount.c for dwarfdump. 2020-11-25 David Anderson * configure.ac: Now version 20201201. * configure: Regenerated. 2020-11-25 David Anderson * configure.ac: Modified to make build endianness visible to dwarfexample 'make check' runtests.sh so make check can pass building on a big-endian host. * Makefile.in: Regenerated. * configure: Regenerated. 2020-11-25 David Anderson * configure.ac: Now version 20201125. * configure: Regenerated. 2020-11-24 David Anderson * CMakeLists.txt: now supports -DDWARF_WITH_LIBELF=OFF (which it was supposed to do...) 2020-11-23 David Anderson * configure.ac: Now version 20201123. * configure: Regenerated. 2020-11-09 David Anderson * configure.ac: Now version 20201100 * configure: Regenerated. 2020-11-05 David Anderson * CMakeLists.txt,configure.ac: Modified so we set both HAVE_ZLIB and HAVE_ZLIB_H as we should have done long ago. * config.h.in,configure: Regenerated. 2020-11-03 David Anderson * configure.ac: Now version 20201103 * configure: Regenerated. 2020-10-20 David Anderson * configure.ac: Now version 20201029 * configure: Regenerated. 2020-10-11 David Anderson * configure.ac: Now version 20201011 * configure: Regenerated. 2020-10-03 David Anderson * Makefile.in,aclocal.m4,ar-lib,compile,configure,depcomp: Running autoreconf on Ubuntu 20.04 caused some small changes. * COPYING: Corrected the references to the BSD copyright to use "two-clause BSD license". 2020-09-26 David Anderson * configure.ac: Now version 20200926 * configure: Regenerated. 2020-09-15 David Anderson * configure.ac: Now version 20200915 Added -fno-omit-frame-pointer to the -fsanitize option set * configure: Regenerated. 2020-09-08 David Anderson * configure.ac: Now version 20200908 * configure: Regenerated. 2020-08-25 David Anderson * configure.ac: Now version 20200825 * configure: Regenerated. 2020-08-22 David Anderson * configure.ac: Now version 20200822 * configure: Regenerated. 2020-08-10 David Anderson * configure.ac: Now version 20200810 * configure: Regenerated. 2020-07-19 David Anderson * configure.ac: Now version 20200719 * configure: Regenerated. 2020-07-14 David Anderson * configure.ac: Now version 20200714 * configure: Regenerated. 2020-07-04 David Anderson * configure.ac: Now version 20200703 * configure: Regenerated. 2020-06-29 David Anderson * configure.ac: Now version 20200629 * configure: Regenerated. 2020-06-17 David Anderson * configure.ac: Now version 20200617 * configure: Regenerated. 2020-06-12 David Anderson * configure.ac: Now version 20200612 * configure: Regenerated. 2020-06-09 David Anderson * configure.ac: Now version 20200601 * configure: Regenerated. 2020-05-19 David Anderson * configure.ac: Now version 20200519 * configure: Regenerated. 2020-05-01 David Anderson * configure.ac: Now version 20200501 * configure: Regenerated. 2020-04-26 David Anderson * configure.ac: Now version 20200426 * configure: Regenerated. 2020-04-13 David Anderson * configure.ac: Now version 20200423 * configure: Regenerated. 2020-04-13 David Anderson * configure.ac: Now version 20200412 * configure: Regenerated. 2020-03-26 David Anderson * configure.ac: Now version 20200327 * configure: Regenerated. 2020-03-15 David Anderson * configure.ac: Now version 20200315 * configure: Regenerated. 2020-03-09 David Anderson * configure.ac: Now version 20200307. * configure: Regenerated. 2020-02-25 David Anderson * configure.ac: now 20200225 * configure: Regenerated. 2020-02-15 David Anderson * configure.ac: Version string now 20200215 as we now deal with libelf-reading-relocation-sections.

If there are expression loops It adds loopcount= to the end of the line (counting the instances of a DW_OP_bra or DW_OP_skip in a negative direction). modified: src/bin/dwarfdump/print_die.c The old names of these functions were a bit misleading. They are for all expressions. dwarfdump_print_location_operations -> dwarfdump_print_expression_operations print_location_operations -> print_expression_operations modified: src/bin/dwarfdump/esb_using_functions.h modified: src/bin/dwarfdump/print_frames.c modified: src/bin/dwarfdump/print_frames.h modified: src/bin/dwarfdump/print_hipc_lopc_attr.c modified: src/bin/dwarfdump/print_tag_attributes_usage.c 2021-11-23: David Anderson commit f3e04e9414fb7ffa10265e2dbca56d2ecb9ada29 Minor tweaks to the vulerabilitie from 2020 modified: bugxml/data.txt 2021-11-22: David Anderson commit 145d3f6af7314dfb6642cd08eb6b0e0ab0bb0524 Now with oss.chromium.org references shown where appropriate. modified: data.txt 2021-11-21: David Anderson commit 9e31d015a40fa1363f9dbf5de1eba8210b72b171 Up to date with git log. modified: ChangeLog 2021-11-21: David Anderson commit 874f6ba514e10ae3df72dfb6b7b549509208d054 Now with gitfixid for ossfuzz41240. modified: bugxml/data.txt 2021-11-21: David Anderson commit a120c808234060c3c9b1872ab9a059aa1ac70b1d This is a fix for the fuzz attack oss-fuzz-41240.

Removed bit-reading of frame instructions as thats no longer necessary, the new function dwarf_get_frame_instruction() does that for us. modified: src/bin/dwarfdump/print_frames.c One internal pointer changed from Dwarf_Ptr to Dwarf_Small * for easier use and better type checking. modified: src/bin/dwarfdump/print_frames.h frame1.c is now using the revised and new frame interfaces. modified: src/bin/dwarfexample/frame1.c createirepfrombinary.cc is doing so too now. modified: src/bin/dwarfgen/createirepfrombinary.cc Rearranged DW_CFA_nop DW_CFA_extended so the nop version is what is printed, not the artificial DW_CFA_extended (both are 0). modified: src/lib/libdwarf/dwarf.h DW_DLA_FRAME_OP replaced by DW_DLA_FRAME_INSTR_HEAD and DW_DLA_FRAME_BLOCK has been dropped. modified: src/lib/libdwarf/dwarf_alloc.c Fixed a comment and pointless whitespace. modified: src/lib/libdwarf/dwarf_debugnames.c Added DW_DLE_CFA_INSTRUCTION_ERROR(485) modified: src/lib/libdwarf/dwarf_errmsg_list.h Dropped the Dwarf_Frame_Op support. Now with some internal args Dwarf_Unsigned where Dwarf_Signed made no sense. modified: src/lib/libdwarf/dwarf_frame.c Dwarf_Frame_Instr_s and Dwarf_Frame_Op_List_s (not visible to library callers) created. Now with some args Dwarf_Unsigned where Dwarf_Signed made no sense. modified: src/lib/libdwarf/dwarf_frame.h Now with some args Dwarf_Unsigned where Dwarf_Signed made no sense. modified: src/lib/libdwarf/dwarf_frame2.c Removed a useless blank line. modified: src/lib/libdwarf/dwarf_line_table_reader_common.h Fixed indents, trailing whitespace. modified: src/lib/libdwarf/dwarf_loc.c A Dwarf_Block field is no Dwarf_Byte_Ptr, identical to Dwarf_Small * modified: src/lib/libdwarf/dwarf_loc.h Removed #if 0 #endif short sequences. modified: src/lib/libdwarf/dwarf_macro.c 'make rebuild' altered this so DW_CFA_nop can be returned as a cfa name string. modified: src/lib/libdwarf/dwarf_names.c Removed trailing whitespace. modified: src/lib/libdwarf/dwarf_object_detector.c Removed a #if 0 endif declaration of code never written. modified: src/lib/libdwarf/dwarf_opaque.h Removed Dwarf_Frame_Op_s. It only ever worked for DWARF2. New opaque structs Dwarf_Frame_Instr_Head_s and Dwarf_Frame_Instr_s make possible easy and improved access to .debug_frame/.eh_frame DW_CFA instructions. Removed DW_DLA_FRAME_OP and added DW_DLA_FRAME_INSTR_HEAD. Added DW_DLE_CFA_INSTRUCTION_ERROR. dwarf_get_cie_info_b() and dwarf_get_fde_range() and dwarf_get_fde_instr_bytes(() now use Dwarf_Small * instead of Dwarf_Ptr as thats easier to use and slightly safer for type checking.. Effectively unsigned char * instead of void * dwarf_get_fde_info_for_reg3_b() dwarf_get_fde_info_for_cfa_reg3_b() uses Dwarf_Small * and also Dwarf_Signed arguments changed to Dwarf_Unsigned to accurately represent the meaning. Adds a Dwarf_Block replacing a pointer/length pair of arguments, dwarf_expand_frame_instructions() arguments much changed to allow access to frame instructions that handle *all* frame instructions, not just DWARF2 dwarf_get_frame_instruction() dwarf_frame_instr_head_dealloc() are new to enable correct printing of frame instructions without decoding the instruction bits. making the argumente clearer. modified: src/lib/libdwarf/libdwarf.h 2021-09-19: David Anderson commit 1c3cce658c068a165d57afd4954f504592c390dc Corrected spelling error. modified: README.md 2021-09-19: David Anderson commit 6f90b971b5847d4bf543e9c866e12817af136249 Now has the latest git log data. modified: ChangeLog 2021-09-19: David Anderson commit 6b7fd93356a1a58275f4014437508eda9aa0272c The 'namestable' options have no effect any longer, so they have been deleted. modified: CMakeLists.txt modified: configure.ac 2021-09-19: David Anderson commit 876c1edbbc6b29d9cd5e6a00372e65c82939e82c Updated comments in the Changes section. modified: libdwarf.mm Rev 4.10 modified: libdwarf.pdf Regenerated 2021-09-19: David Anderson commit dfd515afe38c8d48764b34d1040a8720a6e9fb8e Revised the documentation.

notices instances of multiple blank lines and eliminates all but one of them. Also notices something like } } (with the blank line between) and drops that empty pointless blank line. modified: src/lib/libdwarf/dwarf_frame.c modified: src/lib/libdwarf/dwarf_frame.h modified: src/lib/libdwarf/dwarf_frame2.c modified: src/lib/libdwarf/libdwarf.h 2021-09-13: David Anderson commit 7fc73b9a8bb1a50a003f9ecf1fc31e4ecd6fe813 All the earlier dwarfgen/ChangeLog20xx were left off by 'make dist' and now they apprear properly. modified: src/bin/dwarfgen/Makefile.am 2021-09-13: David Anderson commit 43bdde11b898abcc8c338a48959728d2f38b6162 -" ", +" ", modified: src/bin/dwarfdump/print_die.c 2021-09-13: David Anderson commit 58920809a408eeac18afb1ca14fa5ba545120ae7 A recent update changed things. make dist was now causing test/dummyexecutable to be rebuilt from test/dummyexecutable.c. That was not intended. So renamed dummyexecutable.c so make cannot make the connection or try to rebuild dummyexecutable. This simple change just makes what is going on slightly clearer with respect to the two object sections involved. modified: src/lib/libdwarf/dwarf_debuglink.c This file should not be in libdwarfp, libdwarfp gets the content from libdwarf source. deleted: src/lib/libdwarfp/dwarf_string.c Added an exit 0 so even if run the script does nothing. As intended! It is really documentation and should not be run. modified: test/buildingdummy.sh renamed: test/dummyexecutable.c -> test/dummysourceignore The makefile reflects the name changes so the files get into the make dist output. modified: test/Makefile.am 2021-09-12: David Anderson commit b70c815780a8658592e76ffdcf5c9f8d8284084a Modified libdwarf-internal function names to have a leading _dwarf_ modified: dwarf_frame.c modified: dwarf_frame.h modified: dwarf_frame2.c Deleted dwarf_frame_get_reg_register() and dwarf_frame_get_reg_expression() as they no longer exist and did not work for recent dwarf. modified: libdwarf.h 2021-09-11: David Anderson commit cb86f35166a71eae445715cca9249a18b133745f Updated with files changed due to recent deletion of some blank lines. modified: ChangeLog 2021-09-11: David Anderson commit cccee303f33b8c4dcccaaae236a5922c467eaa77 Each instance of multiple blank lines reduced to a single blank line. modified: buildopstab/buildopscounttab.c modified: gennames/gennames.c modified: tag_attr/tag_attr.c modified: tag_tree/tag_tree.c 2021-09-11: David Anderson commit c55271af36006f2e7ee4bbe4750f3b417b01e0f1 Each instance of multiple blank lines reduced to a single blank line. modified: src/bin/dwarfexample/dwdebuglink.c modified: src/bin/dwarfexample/findfuncbypc.c modified: src/bin/dwarfexample/frame1.c modified: src/bin/dwarfexample/jitreader.c modified: src/bin/dwarfexample/simplecrc.c modified: src/bin/dwarfexample/simplereader.c 2021-09-11: David Anderson commit 7a1d69baa69ea4982b6cfc8de55463a57d7a662b Each instance of multiple blank lines reduced to a single blank line. modified: dwarf_leb_test.c modified: dwarf_tied_test.c modified: getnametest.c modified: getopttest.c modified: makename_test.c modified: test_canonical.c modified: test_dwarfstring.c modified: test_errmsglist.c modified: test_extra_flag_strings.c modified: test_linkedtopath.c modified: test_regex.c modified: testesb.c 2021-09-11: David Anderson commit eb499fc7c60aa9e350f311c8df199d22632d7a59 A new script (not part of libdwarf) now turns a sequence of blank lines into a single blank line.

Ordinary libdwarf use or just Now struct Dwarf_Obj_Access_Interface_a_s struct Dwarf_Obj_Access_Methods_a_s struct Dwarf_Obj_Access_Section_a_s have all the fields they should have had all along, but the member names have appropriate 2-letter prefixes to make it easy to quickly find uses of the members. This only affects those applications reading dwarf from memory (meaning, there is no file existing to read). This is typical for just-in-time (jit) compilers. modified: src/lib/libdwarf/libdwarf.h Now we have a worked out example demonstrating the abilility to use data in memory as DWARF infomation. renamed: jitreader.c -> ../src/bin/dwarfexample/jitreader.c The following were modified to match up with the new names, as libdwarf actually uses, internally, the data in the above-named structs. modified: src/lib/libdwarf/dwarf_elfread.c modified: ./src/lib/libdwarf/dwarf_init_finish.c modified: ./src/lib/libdwarf/dwarf_machoread.c modified: ./src/lib/libdwarf/dwarf_opaque.h modified: ./src/lib/libdwarf/dwarf_peread.c New new file: test/jitreader.base new file: test/jitreaderdiff.sh commit 05b85bc60f0ed9b28088604008a3b5efb1103b6c Author: David Anderson Date: Mon Sep 6 10:53:19 2021 -0700 Renamed the test case to provide a better idea as to what the test shows: accessing all of libdwarf where the DWARF information is not in a file at all, or is in a special file format which is not Elf or PE or MacOS. modified: test/Makefile.am new file: test/jitreader.c deleted: test/objaccess.c commit a10fa8fe5172a2b34bfff163499e48ae7884c761 Author: David Anderson Date: Sat Sep 4 16:47:02 2021 -0700 Added filesize to the access function pointer list, making it possible to correctly deal with file sizes Where it was not previously possible in libdwarf. For callers passing a path or reading via an fd all this is invisible. For people wishing to use dwarf_object_init_b() on DWARF which is in memory (possibly something never on disk) or in a special file format this change makes it possible to have libdwarf work properly and safely. struct Dwarf_Obj_Access_Interface_a_s is similar to the previous struct name, but the members of the struct are ai_object and ai_methods, making it easier to grep for the usage. struct Dwarf_Obj_Access_Methods_a_s is similar to the old struct name but it adds a new method om_get_filesize. And all member names prefixed with om_ so the fields can be found with grep easily. And the order of the values in the struct changed slightly. modified: src/lib/libdwarf/dwarf_elfread.c modified: src/lib/libdwarf/dwarf_generic_init.c modified: src/lib/libdwarf/dwarf_init_finish.c modified: src/lib/libdwarf/dwarf_machoread.c modified: src/lib/libdwarf/dwarf_opaque.h modified: src/lib/libdwarf/dwarf_peread.c modified: src/lib/libdwarf/libdwarf.h 2021-09-04: David Anderson commit 5593a44b4182db596fb2da87f563a7992a4f985f buildopscounttab.c and the table it builds, opscounttab.c, had lines longer than the codingstyle calls for.

Ignore this for now. modified: src/bin/dwarfdump/print_debug_names.c Correcting the use of dwarf_global_formref() where the reference can be DW_AT_type and DW_FORM_ref_sig8 so we understand what section is being targeted by an offset. And can check and report the target die TAG and name (if it has a DW_AT_name). modified: src/bin/dwarfdump/print_die.c Just delete a pointless blank line. modified: src/bin/dwarfdump/print_pubnames.c 2021-07-28: David Anderson commit 0c5199d6a6ced9fa466d6c7632337ddf3519b1e6 These two are not ready to be used. Not yet correct. modified: src/lib/libdwarf/dwarf_debugnames.c modified: src/lib/libdwarf/dwarf_debugnames.h Cleaned up spacing in find_cu_die_base_fields() Added _dwarf_fill_in_abcom_from_context() and _dwarf_fill_in_context_from_abcom so that abbreviations reading is no longer directly tied to .debug_abbrev but can now also be used for the abbreviations table in .debug_names. modified: src/lib/libdwarf/dwarf_die_deliv.c More complete handlilng of is_info for DWARF4 .debug_info/.debug_types. Now we use DW_FORM_ref_sig8 to refer to .debug_types from .debug_info properly. dwarf_global_formref() and dwarf_global_formref_b() exist as the latter is needed for the offset in .debug_types needs to have the is_info =FALSE to check the reference. Other places needed slightly corrected handling of is_info. modified: src/lib/libdwarf/dwarf_form.c Now with a new field, pubnames_context->pu_pub_entries_end_ptr, to provide a sharper 'end of an entries contribution error check' than simply the end of the section. modified: src/lib/libdwarf/dwarf_global.c Added Dwarf_Byte_Ptr pu_pub_entries_end_ptr; for the improved checking. modified: src/lib/libdwarf/dwarf_global.h Now with _dwarf_fill_in_context_from_abcom() and _dwarf_fill_in_abcom_from_context() to isolate abbreviation reading from any specific section. modified: src/lib/libdwarf/dwarf_opaque.h Using _dwarf_fill_in_context_from_abcom() and _dwarf_fill_in_abcom_from_context() to isolate abbreviation reading from any specific section. modified: src/lib/libdwarf/dwarf_query.c Now using internal struct Dwarf_Abbrev_Common_s to isolate abbreviation reading from any specific section. modified: src/lib/libdwarf/dwarf_util.c Declares a revised struct Dwarf_Abbrev_Common_s. modified: src/lib/libdwarf/dwarf_util.h dwarf_formref now adds a Dwarf_Bool *is_info argument so we can fully treat DWARF4 debug_info/debug_names properly. This is a change to dwarf_formref() argument list. Added dwarf_global_formref_b() to return an is_info flag along with the offset (for DWARF4 section .debug_info or .debug_names that offset applies to) Some dwarf_dnames function prototypes changed, but those are not yet correct, ignore them. modified: src/lib/libdwarf/libdwarf.h 2021-07-28: David Anderson commit 81ee54de5c146282fec67dec9375103c1069d61d Uses dwarf_formref/dwarf_global_formref correctly, recognizing the is_info argment for DWARF4 debug_info/debug_types. shortened a couple too-long lines. modified: src/bin/dwarfgen/createirepformfrombinary.cc 2021-07-23: David Anderson commit bbbca00128b70a25ecb7132c90ee494abad5b692 DO NOT USE THIS COMMIT YET. modified: src/lib/libdwarf/dwarf_form.c 2021-07-23: David Anderson commit ad4aebecce0c6a8d4fe23f8d3c509754fd04937d DO NOT USE THIS COMMIT YET.

Ensure that --file-line5= only requests s2l and singldw5 (dwarfdump enum values) so we just call the desired functions. modified: src/bin/dwarfdump/command_options.c Refactor some check code into a new local check_last_line_of_table() to shorten a long function. delete the code for lines enum values org and orig2l. modified: src/bin/dwarfdump/print_lines.c Now use dwarf_srclines_b() and dwarf_srclines_from_linecontext() instead of the old way. modified: src/bin/dwarfgen/createirepfrombinary.cc Delete dwarf_srclines as obsolete.

It's not essential, but looks better. In pro_opaque.h the values matter as they must match locations in a C array. So we changed the values (and in two cases names) in glflags.h to match.

We add a specific field to count the balanced tree depth instead of using strange pointer arithmetic on llink. No need for pointer arithmetic at all. There is a better way to do this using a HEAD separate struct and a pointer-to an rlink field as that would reduce struct size here, but we are postponing that for now. modified: src/bin/dwarfdump/dd_tsearchbal.c 2022-09-01: David Anderson commit f7015bda84749ef4f9b4746bbb3834087adba8cd Another set-but-not-used variable.

So now we name python3 and Linux and msys2 work for these tests. modified: test/CMakeLists.txt Added a little bit of testing host_os to drop 'debuglinktest-a.sh' and 'debuglinktest-b.sh' from ninja test as getting the Windows output to match Unix/Linux baseline files to match Windows environmengs is ...not working. modified: test/meson.build 2022-08-15: David Anderson commit 00c79fc290777061042d72d52099539c264b1011 This is for regression testing to attempt to make Windows paths look like Unix paths so we can have a single baseline for all OS's. Note that it's not *really* working right yet so for Windows the two actual tests (debuglink) are not run. The msys2 vs Windows paths combined with what dwdebuglink does with paths makes sort of a mess... modified: test/transformpath.py 2022-08-15: David Anderson commit bc9f1f04c543382b1e11446a1df0774e6ad70f0b Changed temp file names for consistency in file naming.

Just the "=====done with" line changed. modified: test/debuglink.base modified: test/debuglink2.base 2022-08-15: David Anderson commit 7ad43120effcf43d2d524d20a85e2685eff9b306 To ease comparisons against a baseline the "=======done with" output line just lists the file basename. No directories shown. modified: src/bin/dwarfexample/dwdebuglink.c 2022-08-14: David Anderson commit 8cdf8f0fd1d02e3781d76989642971d9e391812a Changes to let the basic checks (make check, ninja test) work properly on Windows (there is no change to the linux debuglink output).. modified: src/lib/libdwarf/dwarf_debuglink.c modified: test/transformpath.py 2022-08-13: David Anderson commit 456736367be280efd5f910448c127687ae7cbe59 delete obsolete comment. modified: src/lib/libdwarf/dwarf_debuglink.c Now uses the new python code for helping allow identity to baselines checking just like test/debuglinktest-a.sh does. Was an oversight this was not done earlier. modified: test/debuglinktest-b.sh 2022-08-13: David Anderson commit bd14b6128ca5ce2b63e465950291d2de28b6a3a9 Eliminated unused arg from print_usage_message() Changed int to Dwarf_Signed so pointer subtraction is handled correctly. modified: bin/attr_form/attr_form_build.c modified: bin/dwarfdump/dd_checkutil.c modified: bin/dwarfdump/dd_command_options.c modified: bin/dwarfdump/dd_common.c modified: bin/dwarfdump/dd_common.h modified: bin/tag_attr/tag_attr.c modified: bin/tag_tree/tag_tree.c Removed NULL_DEVICE_NAME define as it is not used here. modified: lib/libdwarf/dwarf_debuglink.c modified: lib/libdwarf/dwarf_util.c 2022-08-12: David Anderson commit ee6f657efcb025f4333654ca351d9fa500d685d0 Now up to date with git log text. modified: ChangeLog 2022-08-12: David Anderson commit ba778304169ddae8d66fd09e4b6d22a68c1341ba Removed an assign in a test.

Updated the required version to 0.56 as this is the version required to support the project*() commands we now use. Also added code to look in specific directories beyond the standard locations for zlib and libzstd (/opt/local/lib and /usr/local/lib) so the build can work in more environments. modified: meson.build modified: test/meson.build 2023-10-25: zerons commit 809f32b7664f04a9cec28dd1a518725190a26cbd handle DW_AT_data_bit_offset in get_attr_value() (#189) An oversight that this pull fixes. 2023-10-24: David Anderson commit 0e6464b2a55c6a3355695ef9500b79c5d8863ed7 Minor correctsions for meson modified: README.md Toward making it all work more places. modified: meson.build Making it more tolerant of warnings from compilers. modified: scripts/allsimplebuilds.sh Removing unused locals. modified: src/bin/dwarfgen/createirepfrombinary.cc modified: src/bin/dwarfgen/dwarfgen.cc modified: src/lib/libdwarfp/dwarf_pro_section.c Correcting build args for libdwarfp modified: src/lib/libdwarfp/meson.build Removing obsolete ifdef as we do not test that C90 header files exist modified: test/test_macrocheck.c 2023-10-22: David Anderson commit ea1d31e8f88104fcf9a86f529615981b964b7b66 Now present with just a 2 line comment. new file: README 2023-10-22: David Anderson commit 0402c07c9d87dc9aa76681ce11de8f0fc3c35b43 A change to Makefile.am means we can delete this now, leaving README.md . deleted: README 2023-10-22: David Anderson commit d5f0e75ee93986404d69c96d483e3ade6a520a2a All have basically the same line added to each executable(), adding a "link_args :" so that the -fsanitize options are passed to the link step as well as compile steps when running the gcc -fsanitize options. modified: meson.build modified: src/bin/attr_form/meson.build modified: src/bin/buildopstab/meson.build modified: src/bin/builduritable/meson.build modified: src/bin/dwarfdump/meson.build modified: src/bin/dwarfexample/meson.build modified: src/bin/dwarfgen/meson.build modified: src/bin/gennames/meson.build modified: src/bin/tag_attr/meson.build modified: src/bin/tag_tree/meson.build modified: test/meson.build 2023-10-21: David Anderson commit f1408bf9e7c98654173fbf5672ee3671e7db0e21 Documented new fde 0.9.0 fde frame function in the Changes section modified: doc/libdwarf.dox 2023-10-21: David Anderson commit 37c0c26e48754ee69288d73f238d4f54ce957fdb Now checks if required functiosn exist and sets HAVE_UTF8 inconfig so dwarfdump built with meson and print UTF8 properly. modified: meson.build Added options sanitize as in -Dsanitize=true so we can use -fsanitiz3 and wall as in -Dwall=false so we can turn off warnings as errors. modified: meson_options.txt 2023-10-21: David Anderson commit 6504fba6ee02c47517489040afa574a040166478 All these additionally compile dwarfdump_dd_utf8.c so they build with meson (required for swithching regressiontests to building with meson) modified: src/bin/attr_form/meson.build modified: src/bin/dwarfdump/meson.build modified: src/bin/tag_attr/meson.build modified: src/bin/tag_tree/meson.build 2023-10-21: David Anderson commit 15d2a8aed6f46f24ba907c181efd3789fec499f5 libdwarfp was misnamed resulting in generating src/lib/libdwarfp/liblibdwarfp.a Fixed now. modified: src/lib/libdwarfp/meson.build 2023-10-21: David Anderson commit a377f4f21942e20b8a391a3092d402eb3ff09c3f Left-over references to libelf functions removed. modified: src/lib/libdwarfp/meson.build 2023-10-21: David Anderson commit d493bd62b64f157b27529da897ddaf7b1678e33a Added another example of getting frame registers using the latest new frame function in libdwarf.h, modified: src/bin/dwarfexample/frame1.c 2023-10-21: David Anderson commit ec9e7b682f198fdc4b735ca5487b724263b95584 When printing lines about dSYM or debuglink paths returned change the prefix of the output to $HOME if that is equivalent to what is the returned string.

Was failing to check, very early on, for an incomplete Mach-O universal object. modified: src/lib/libdwarf/dwarf_machoread.c Here is the timeline of Apple Universal Binary handling in libdwarf: 2023-09-20 In github libdwarf-code discussion #185 asks if libdwarf supports Mach-O universal objects, which We will abbreviate here as Apple Universal Objects (AUB). Each AUB may have a number of Mach-O executables inside. 2023-09-21 Initial commit in the readelfobj-code project of code reading AUB. 2023-09-26 Completed code handling AUB in readelfobj-code project.. 2023-09-27 In the libdwarf-code project we do a little code cleanup related to Mach-O object files. Added a new API function for AUB in libdwarf.h 2023-09-29 Initial commit in dwarfdump so dwarfdump can select what Mach-O object in an AUB to report on (defaults to object 0(zero)). 2023-09-29 Full AUB support is now public on github, 2023-09-30 DW202309-002 ossfuzz id 62833 DW202309-003 ossfuzz id 62834 DW202309-004 ossfuzz id 62842 reported.

Now they only appear when doing'checking. It has to do with line (table) details details suceeding or (in 3 test objects) failing. Now we don't print the DWARF_CHECK if printing. modified: src/lib/libdwarf/dwarf_line.c A fix to oss fuzz 57711. A problem present for many years. A crash due to a negative value in a line table Dwarf_Signed API. The stack trace shown was pretty crazy (a mess). Many places were having trouble checking bounds due to the historic choice of Dwarf_Signed in the API interfaces but Dwarf_Unsigned internally (as Dwarf_Unsigned is really the only sensible choice). So now we explicitly check for value < 0 (where that makes sense) so even with signed values we can do other checks without worrying about negative values. modified: src/lib/libdwarf/dwarf_line_table_reader_common.h 2023-04-06: David Anderson commit 89ebcaffd9913e371b8f7e2afd72e097350067ab Dated April modified: bugxml/dwarfbug.html modified: bugxml/dwarfbuglohi.html 2023-04-06: David Anderson commit 8d08175af2b842e2994e2ffae1945273c23a1470 now the date prints as January 2023 instead of with a specific date and time.

The infinite loop was caused by letting internal function _dwarf_find_CU_Context_given_sig() unconditionally do too much in the middle of setting up a CU_Context (by letting it start more CU_contexts(). The implicit infinite loop has been there a few years, depending on the correctness of object files DWARF4/DWARF5 being read. Calls new internal _dwarf_internal_global_formref_b() (which is also called by dwarf_global_formref_b() with its specific new argument at zero) So for internal-library-use we can make modified: src/lib/libdwarf/dwarf_die_deliv.c Introduced a new function _dwarf_internal_find_die_given_sig8() with a new argument and now API function dwarf_find_die_given_sig8() just calls the new function with a specific value (0) of the new argument for the general case. Added a #if 0 dump_bytes() local function for debugging of Sig8 values. Added a new argument to _dwarf_find_CU_Context_given_sig() so it can properly decide whether it should create new CU_Contexts or not. modified: src/lib/libdwarf/dwarf_find_sigref.c file-static find_sig8_target_as_global_offset() added the new argument to help fix the infinite loop.

My mistake having a new incomplete version visible. modified: dwarf_rnglists.c 2023-03-20: David Anderson commit fcbbee163bbdfbba7def899d3628b912649c724e Latest changes from git log modified: ChangeLog 2023-03-20: David Anderson commit 1ff4365bd64a4e4f9ab717b3f62589c2ba6637a5 ossfuzz id 56540. ossfuzz id 56487. ossfuzz id 56480. ossfuzz id 56497. These fixes are to the tests, not the library. Several had code that was going to crash due to mistakes in the test code itself. Removed all instances of free(errp) where errp is Dwarf_Error *errp as that is never necessary or appropriate. Any leftover allocations made in libdwarf and not 'dwarf_dealloc*' or documented as user-must-free data returned via pointers to the caller are automatically freed by dwarf_finish() unless there are libdwarf bugs. modified: fuzz_die_cu.c modified: fuzz_die_cu_attrs.c modified: fuzz_die_cu_info1.c modified: fuzz_die_cu_offset.c modified: fuzz_die_cu_print.c modified: fuzz_macro_dwarf5.c modified: fuzz_showsectgrp.c modified: fuzz_simplereader_tu.c modified: fuzz_srcfiles.c modified: fuzz_stack_frame_access.c modified: fuzz_xuindex.c 2023-03-20: David Anderson commit 16a4078e91cf8c695b491c6fbcbe14f4e7ec02b8 Before dereferenceing errp ensure errp is not NULL. modified: fuzz_debug_addr_access.c modified: fuzz_findfuncbypc.c modified: fuzz_set_frame_all.c 2023-03-20: David Anderson commit 2eced75af9903ab778c3b237ec7be3ddc93ea6ec ossfuzz 56568 All instances of Dwarf_Error error; changed to Dwarf_Error error = 0; to avoid unwanted stack random bytes in the pointer. modified: fuzz/fuzz_aranges.c modified: fuzz/fuzz_crc_32.c modified: fuzz/fuzz_debug_str.c modified: fuzz/fuzz_die_cu.c modified: fuzz/fuzz_die_cu_attrs.c modified: fuzz/fuzz_die_cu_attrs_loclist.c modified: fuzz/fuzz_die_cu_info1.c modified: fuzz/fuzz_die_cu_offset.c modified: fuzz/fuzz_die_cu_print.c modified: fuzz/fuzz_dnames.c modified: fuzz/fuzz_findfuncbypc.c modified: fuzz/fuzz_gdbindex.c modified: fuzz/fuzz_globals.c modified: fuzz/fuzz_gnu_index.c modified: fuzz/fuzz_init_b.c modified: fuzz/fuzz_macro_dwarf4.c modified: fuzz/fuzz_macro_dwarf5.c modified: fuzz/fuzz_set_frame_all.c modified: fuzz/fuzz_simplereader_tu.c modified: fuzz/fuzz_srcfiles.c modified: fuzz/fuzz_stack_frame_access.c modified: fuzz/fuzz_str_offsets.c modified: fuzz/fuzz_xuindex.c modified: src/lib/libdwarf/dwarf_rnglists.c 2023-03-20: David Anderson commit 59f5769780213c8fc4c82efbd829cc02fd13ef8c Most recent generated. modified: bugxml/dwarfbug.html modified: bugxml/dwarfbuglohi.html 2023-03-20: David Anderson commit c04edfaf20904ee70e867afbf0ee87fb939ec42b new file: fuzz_debug_addr_access.c 2023-03-18: David Anderson commit fafb744cfceaa53fd153a33af38f6105af9b00cf generated files. modified: bugxml/dwarfbug.html modified: bugxml/dwarfbug.xml modified: bugxml/dwarfbuglohi.html 2023-03-14: David Anderson commit 003fb181750f499f4fd30fe7908c82fd5de62d2e Improved a rather useless error message. modified: src/bin/dwarfdump/print_gdbindex.c 2023-03-14: David Anderson commit 8e935967d3415296f8d3886618dda7f554b16f8d Brought up to date with the oss-fuzz fixed so far. modified: data.txt 2023-03-14: David Anderson commit e564c9350c104f16eb2223d7b29082e3deb5d2fb Added many checks for valid pointers and offsets.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same timestamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details. libdwarf-code-0.11.1/Makefile.am000066400000000000000000000044231472336503500163430ustar00rootroot00000000000000###Copyright (C) 2018 Vincent Torri nine-deep dwarfdump switches from indentation by spaces to a nest-level number. 2020-09-08: libdwarf/dwarfdump work well with DWARF4 and DWARF5, including DWP files. 2020-07-08: libdwarf now reads .debug_gnu_pubtypes & pubnames (non-standard but gcc creates them in DWARF5) via a small number of new functions and dwarfdump --print-debug-gnu prints both sections. Verifying the .debug_info offsets is not yet done. 2020-06-29: Dwarfdump now dumps DWARF5 .debug_rnglists and .debug_loclists. To handle DWARF5 there are a small number of new functions. All existing functions are still supported, but to read DWARF5 some small changes are required. In libdwarf see libdwarf2.1.pdf and also see libdwarf/ChangeLog for details. 2020-05-23: dwarfdump now takes much less malloc() to work, as measured by valgrind --tool=massif and massif-visualizer. A dwarfdump run that did 2.2Gib of malloc/free before the changes now does 1.4GiB. 2020-05-19: libdwarf and dwarfdump now support DWARF5 .debug_rnglists. The new interfaces are documented in libdwarf/libdwarf2.1.pdf. The new option to dwarfdump is "--print-raw-rnglists". 2019-11-04: The code (dwarfdump/libdwarf), regressiontests, and readelfobj directories and all their tests are known to work on Linux(Ubuntu on x86_64 and i686), FreeBSD, MacOS Catalina (with Apple Command Line Tools), and IBM s390 (Big Endian!) running Ubuntu Linux. On Windows-MinGW the full regression tests have not been tested, but 'make check' works for dwarfdump/libdwarf (the current dwarfdump make check actually does run dwarfdump and checks that dwarfdump basically works). 2019-04-16: Now a --disable-libelf configure/build of libdwarf/dwarfdump can read elf, mach-o DSYM, and PE executable/dll object files. Such a build will not need or use libelf or elf.h . The dwarfdump options that display Elf section headers or relocation record data are not available in a --disable-libelf build. Nor is dwarfdump's support of reading archive files available in a --disable-libelf build. This libdwarf detects corrupt Elf object files much sooner than before, but does not explain what the corruption really is. Use GNU readelf (or readelfobj, a project on sourceforge) to get more detail about the problems found. See https://www.prevanders.net/dwarf.html for the git clone command for readelfobj. With --disable-libelf the --enable-dwarfgen option does not work: the dwarfgen build will fail. 2019-02-18: For building on machines without a usable elf.h or libelf but possibly with a libelf.h visible, --disable-libelf ensures the build won't use libelf or elf.h anywhere. -lz will be done if zlib.h is visible, independent of libelf, libelf.h, and elf.h 2019-02-08: If one has a standard Bourne shell (sh) available (such as sh on MacOS and sh in MinGW on Windows) one may be able to build libdwarf and dwarfdump natively and they can read Mach-o dSYM and PE object files to access DWARF information. This has NOT been tested under MacOS, so will likely fail on MacOS. No elf.h, libelf.h or zlib.h should be present. For example, the following is known to work under MinGW and this general plan applies to all builds including all builds with elf.h and libelf: mkdir test cd test #(copy the source tree into test, if from git #the name of the top level will likely be 'code') cd code sh -x scripts/FIX-CONFIGURE-TIMES cd .. mkdir bld cd bld ../code/configure (choose your preferred options here) make 2019-01-15: The pre-build dwarf_names.[hc] and the tag related files are now part of the standard build so there is no longer any two-stage aspect of the build. The build simply compiles files in the distribution. If you use git to access the source be sure to sh scripts/FIX-CONFIGURE-TIMES to adjust the file timestamps as having timestamps in the right relationships is vital and git does not maintain timestamps. The script is always safe to run. It takes about 30 seconds. 2018-12-22: The complicated process of building certain .c and .h files has been relegated to the few people updating files libdwarf/libdwarf.h.in, libdwarf/dwarf_errmsg_list.h, dwarfdump/tag_attr_ext.list,dwarfdump/tag_attr.list, dwarfdump/tag_tree_ext.list, and dwarfdump/tag_tree.list. For everyone else the build is simply compiling the .c and .h files in the distribution. Simpler. sh scripts/buildstandardsource.sh creates these files. 2018-10-22: dwarfdump can now dump mach-o (MacOS) dSYM dwarf. All the usual libdwarf interfaces work. A new libdwarf initialization call dwarf_init_path() may be convenient for you to use. 2018-08-05: dwarfdump.conf is now installed by make install in /shared/libdwarf/dwarfdump . Any dwarfdump.conf or .dwarfdump.conf in your $HOME directory will be found before the one in shared. The file is only opened when one wants a more accurate register naming in frame reports (the default is just to name things r54 etc, choosing the right abi with -x abi= can be helpful at times). 2018-06-24: The configure has been completely rewritten to follow current standards and practices. For simple builds the standard ./configure make works as always, but the generated libdwarf.a appears in libdwarf/.libs/libdwarf.a , as does the shared object if "./configure --enable-shared" is used. To build dwarfgen one adds the configure option --enable-dwarfgen instead of using 'make all'. To build the example code one adds the configure option --enable-dwarfexample instead of using 'make all'. "mkdir /tmp/bld ; cd /tmp/bld ; /configure" continues to work, as does configure --host= . 2018-06-14: A small simplification of build options simplifies building across different environments. If your environment needs to use the non-standard elf_open() call instead of unix/linux open() then do /configure --enable-elf-open which sets HAVE_ELF_OPEN in config.h. 2018-03-27: All the DWARF5 FORMs appear to be dealt with. It's now possible to cross-compile libdwarf and dwarfdump. See the README. 2016-11-30: An alternative build mechanism using cmake is now in the source tree. The builds for product testing continue to be done using configure && make. 2016-09-20: --enable-sanitize option added to configure. This builds with -fsanitize=address to check for out of bounds memory access. 2016-09-05: dwarfexample/simpleexample.c now has a simple option letting one extract all .debug_info, .debug_types strings into a file by themselves in case one wanted to examine string frequencies, for example. 2016-06-01: Now we use DW_VERSION_DATE_STR for dates everywhere instead of __DATE__ __TIME__ so a repeated build gets identical object output. DW_VERSION_DATE_STR is updated by UPDATEDWARFDUMPVERSION.sh wherever that string is needed. 2015-11-26: If DWARF section data you intend to read with libdwarf is compressed by zlib (a section name like .zdebug_info indicates such compression) libdwarf etc will need zlib's headers and archive or shared-library at build and link time. If you do not have zlib everything will compile fine and will work on ordinary DWARF sections but libdwarf will not be able to read .zdebug_ compressed sections. zlib.h is the main zlib header and libz.a is the most likely zlib library you will encounter. 2015-11-15: It is now possible to build outside of the source tree. See README. So configure.in changed a little. 2015-01-13: Removed dwarfdump2 and references to it. dwarfdump has the (tsearch) features needed so the C++ version no longer a benefit. libdwarf-code-0.11.1/README000066400000000000000000000000441472336503500151620ustar00rootroot00000000000000### Nothing here. ### See README.md libdwarf-code-0.11.1/README.md000066400000000000000000000311101472336503500155570ustar00rootroot00000000000000# This is libdwarf README.md Updated 29 November 2024 ## Goal Libdwarf has been focused for years on both providing access to DWARF2 through DWARF5 data in a portable way while also detecting and reporting if the DWARF is corrupted and avoiding run-time crashes or memory leakage regardless how corrupted the DWARF being read may be. The intent is to provide ABI independent access to DWARF data and ensure that data returned by the library is meaningful. When the DWARF6 standard is released by the DWARF committee support will be added (as soon as reasonably possible) to libdwarf for all changes/additions while continuing to support previous versions. ## github actions ci runs builds on Linux, Freebsd, msys2, and MacOS using configure,cmake, and meson.

Version 0.9.0 Released 8 December 2023. ## NOTE on linking against libdwarf.a If you are linking code against a static library libdwarf.a You must arrange to define the macro LIBDWARF_STATIC in compiling your code that does a #include "libdwarf.h". See also READMEwin-msys2.md ## REQUIREMENTS from a libdwarf.tar.xz Mentioning some that might not be automatically in your base OS release. Restricting attention here to just building libdwarf and dwarfdump. Nothing in the project requires or references elf.h, libelf.h, or libelf as of 29 June 2023, version 0.8.0. If the objects you work with do not have section content compressed with zlib(libz) or libzstd neither those libraries nor their header files are required for building/using libdwarf/dwarfdump. Ubuntu: sudo apt install xz pkgconf zlib1g zlib1g-dev libzstd1 sudo apt install libzstd-dev # Use of libzstd1 is new in 0.4.3 # zlib1g zlib1g-dev libzstd1 are all optional but # are required to read any DWARF data in compressed # sections. libzstd1 was used by many linux system utilities # in Ubuntu 20.04. optional add: cmake meson ninja doxygen FreeBSD: pkg install bash xz python3 gmake liblz4 zstd # libzstd is likely in /usr/local/lib and zstd.h # in /usr/local/include and the compiler may not look there # by default. All will still build fine without it and # without lzib too, though compressed DWARF sections # may not be readable. # example: CPPFLAGS="-I/usr/local/include/" LDFLAGS="-L/usr/local/lib" ./configure optional add: binutils cmake meson ninja doxygen Ensure that all the needed programs are in $PATH, including python3. # candidate command to make python3 visible (as root) # something like: cd /usr/local/bin ; ln -s python3.9 python3 ## BUILDING from a libdwarf.tar.xz This is always recommended as it's not necessary to have GNU autotools installed. These examples show doing a build in a directory different than the source as that is generally recommended practice. ### GNU configure/autotools build Note: if you get a build failure that mentions something about test/ and missing .Po object files add --disable-dependency-tracking to the configure command. rm -rf /tmp/build mkdir /tmp/build cd /tmp tar xf /libdwarf-0.4.2.tar.xz cd /tmp/build /tmp/libdwarf-0.4.2/configure make make check ### cmake build READMEcmake.md has details on the available cmake options. We suggest that you will find meson a more satisfactory tool. ### meson build meson 0.45.1 on Ubuntu 18.04 fails. meson 0.55.2 on Ubuntu 20.04 works. meson 0.60.3 on Freebsd 12.2 and Freebsd 13.0 works. See READMEwin-msys2.md for the mingw64 msys2 packages to install and the command(s) to do that in msys2. The tools listed there are also for msys2 meson and autotools/configure. The msys2 meson ninja install not only installs libdwarf-0.dll and dwarfdump.exe it updates the executables in the build tree linking to that dll so all such executables in the build tree work too. For example (all build environments): meson /tmp/libdwarf-0.4.2 ninja ninja install ninja test For a faster build, adding additional checks: export CFLAGS="-g -pipe" export CXXFLAGS="-g -pipe" meson /tmp/libdwarf-0.4.2 -Ddwarfexample=true ninja -j8 ninja install ninja test To build a libdwarf that does not refer to or link with decompression libraries zstd or zlib, add the meson option "-Ddecompression=false" ## BUILDING example showing simple builds: This checks for the existence critical executables such as cmake,meson,and ninja and only runs builds that could work. Useful in any supported environment. sh scripts/allsimplebuilds.sh ## BUILDING on linux from a git clone with configure/autotools Ignore this section if using meson (or cmake). This is not recommended as it requires you have more software installed. For Ubuntu configure, install additional packages: autoconf automake libtool pkg-config For FreeBSD configure, install additional packages: autoconf automake libtool pkgconf Here we assume the source is in a directory named /path/to/code For example, on Ubuntu 20.04 ``` sudo apt-get install autoconf libtool pkg-config ``` Note: if you get a build failure that mentions something about test/ and missing .Po object files add --disable-dependency-tracking to the configure command. Using the source/build directories from above as examples, do : # Standard Linux Build cd /path/to/code sh autogen.sh cd /tmp/build /path/to/code/configure make make check ## BUILDING on MacOS from a git clone configure /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" brew install autoconf automake libtool # Then use the Standard Linux Build lines above. ### Options to meson on Linux/Unix For the basic configuration options list , do: meson configure /path/to/code To set options and show the resulting actual options: # Here just setting one option. meson setup -Ddwarfexample=true . /home/davea/dwarf/code meson configure . The meson configure output is very wide (just letting you know). ### Options to configure/autotools on Linux/Unix For the full options list , do: /path/to/code/configure --help By default configure compiles and uses libdwarf.a. With `--enable-shared --disable-static" appended to the configure step, libdwarf.so is built and the runtimes built will reference libdwarf.so. As of version 0.9.1 the configure option "--disable-decompression" tells the build to compile libdwarf and dwarfdump with no reference to the zlib or zstd libraries. If you get a build failure that mentions something about test/ and missing .Po object files add --disable-dependency-tracking to the configure command. With that option do not assume you can alter source files and have make rebuild all necessary. See: https://www.gnu.org/savannah-checkouts/gnu/automake/history/automake-history.html#Dependency-Tracking-Evolution Other options of possible interest: --enable-wall to turn on compiler diagnostics --enable-dwarfexample to compile the example programs. configure -h shows the options available. Sanity checking: gcc has some checks that can be done at runtime. -fsanitize=undefined is turned on for configure by --enable-sanitize ### Options to meson on linux MacOS Windows (Msys2) As of 0.9.0 meson builds default to be shared-library builds. These options go on the meson setup command line. the default can be explicitly chosen with: --default-library shared A static libdwarf (archive) libdwarf.a can be built with --default-library static By default compiler warnings are errors. Add the following to let compilations continue: -Dwerror=false By default compiles look for C/C++ language issues. Add the following to add gcc -fsanitize checking in the build to catch various memory errors (the generated code is larger and slower than normal). -Dsanitize=true ### Options to configure on Windows (Msys2) All libdwarf builds are automatically shared object (dll) builds. No static libdwarf.a can be built. If you need static libdwarf.a use meson or cmake. Has the same meson setup reporting as on Linux (above). See READMEwin-msys2.md ### Distributing via configure/autotools When ready to create a new source distribution do a build and then make distcheck # INCOMPATIBILITIES. Changes to interfaces ### Comparing libdwarf-0.11.0 to libdwarf-0.9.1 Added dwarf_get_ranges_baseaddress() to the API. ### Comparing libdwarf-0.9.1 to libdwarf-0.9.0 Altered the type of the return value of dwarf_die_abbrev_code() and dwarf_get_section_count() from int to Dwarf_Unsigned for consistency (should always have been this way). ### Comparing libdwarf-0.9.0 to libdwarf-0.8.0 New interfaces allow full support for Mach-O (Apple) universal binaries: dwarf_init_path_a(), dwarf_init_path_dl_a(), and dwarf_get_universalbinary_count(). ### Comparing libdwarf-0.8.0 to libdwarf-0.7.0 The default build (with meson) is shared-library. to build with static (archive) libdwarf add --default-library static to the meson command line (applies to meson builds in Linux,Macos, and Windows-mingw). On Windows-mingw one can build static libdwarf when using cmake or meson (configure will not allow a static libdwarf to be built on Windows). See Options to meson on Windows (Msys2) above. ### Comparing libdwarf-0.7.0 to libdwarf-0.6.0 struct Dwarf\_Obj\_Access\_Methods\_a\_s changed for extended ELF so the library can handle section count values larger than 16bits. dwarf\_dnames\_abbrev\_by\_code() and dwarf\_dnames\_abbrev\_form\_by\_index() were removed from the API, better alternatives already existed. ### Comparing libdwarf-0.6.0 to libdwarf-0.5.0 The dealloc required by dwarf\_offset\_list() was wrong, use dwarf\_dealloc(dbg, offsetlistptr, DW_DLA_UARRAY). The function dwarf\_dietype\_offset() has a revised argument list so it can work correctly with DWARF4. dwarf\_get\_pubtypes() and similar changed to eliminate messy code duplication. Fixed memory leaks and treatment of DW\_FORM\_strx3 and DW\_FORM\_addrx3. ### Comparing libdwarf-0.5.0 to libdwarf-0.4.2 dwarf\_get\_globals() is compatible but it now returns data from .debug\_names in addition to .debug\_pubnames (either or both could be in an object file). New function dwarf\_global\_tag\_number() makes the data from .debug\_names a bit more useful (if a library user wants it). Three new functions were added to enable printing of the .debug_addr section independent of other sections and the new dwarfdump option --print-debug-addr prints that section. ### Comparing libdwarf-0.4.2 to libdwarf-0.4.1 No incompatibilities. ### Comparing libdwarf-0.4.1 to libdwarf-0.4.0 Added a new function dwarf\_suppress\_debuglink\_crc() which speeds up gnu debuglink (only use it if you are sure the debuglink name-check alone is sufficient). ### Comparing libdwarf-0.4.0 to libdwarf-0.3.4 A few dealloc() functions changed name to have a consistent pattern for all such. Access to the DWARF5 .debug\_names section is now fully implemented. See the Recent Changes section in libdwarf.pdf (in the release).

Or see (via download) the latest pdf html version [dwpdf]. Notice the table of contents at the right edge of the html page. ## Reading DWARF from memory If one has DWARF bytes in memory or in a kind of file system libdwarf cannot understand one should use dwarf_object_init_b() ...call libdwarf functions... dwarf_object_finish() and create source to provide functions and data for the three struct types: struct Dwarf_Obj_Access_Interface_a_s struct Dwarf_Obj_Access_Methods_a_s struct Dwarf_Obj_Access_Section_a_s These functions and structs now seem complete (unlike the earlier libdwarf versions), hence the name and content changes. For a worked out example of reading DWARF direct from memory with no file system involved see src/bin/dwarfexample/jitreader.c and see the html [dwhtml] (www.prevanders.net/libdwarfdoc/index.html). The latest pdf is [dwpdf] (www.prevanders.net/libdwarf.pdf) David Anderson. libdwarf-code-0.11.1/READMEcmake.md000066400000000000000000000046621472336503500165740ustar00rootroot00000000000000# Cmake on Unix/linux/MacOS/FreeBSD/OpenBSD Created 26 April 2019 Updated 19 December 2023 Consider switching entirely to meson for your build. Unless a shared library is specifically requested cmake builds a static library: libdwarf.a For cmake, ignore the autogen.sh script in the base source directory, autogen.sh is only for configure. By default cmake builds just libdwarf and dwarfdump and libdwarf is a static (archive) library. To switch to a shared library output with cmake add the following to the cmake command: -DBUILD_SHARED=YES -DBUILD_NON_SHARED=NO Lets assume the base directory of the the libdwarf source in a directory named 'code' inside the directory '/path/to/' Always arrange to issue the cmake command in an empty directory. If you are building a Shared Library you may need to install before running tests to allow the tests to work Use -DCMAKE_INSTALL_PREFIX=/some/path to chose the install path. You can install in any temporary directory or in system directories and the tests will work. # build the fast way mkdir /tmp/cmbld cd /tmp/cmbld cmake -G Ninja -DDO_TESTING:BOOL=TRUE /path/to/code ninja ninja test # slower build mkdir /tmp/cmbld cd /tmp/cmbld cmake -G "Unix Makefiles" -DDO_TESTING:BOOL=TRUE /path/to/code make ctest -R self It is best to specify -G explicitly since some versions of cmake seem to have a different default for -G than others. On Windows msys2 -DBUILD_SHARED=YES will build libdwarf.dll. To show all the available cmake options for 'code': cmake -L /path/to/code For dwarfexample: cmake -G Ninja -DBUILD_DWARFEXAMPLE=ON /path/to/code make or cmake -G "Unix Makefiles" -DDO_TESTING=ON /path/to/code make # To list the tests ctest -N # To run all the tests (their names start with # the letters 'self'). ctest -R self To turn off linking with or using zlib or zstd libraries or headers there is an option to cmake as of libdwarf 0.9.1: cmake -G Ninja -DENABLE_DECOMPRESSION=NO /path/to/code By default ctest just shows success or failure with no details. To debug a cmake test, for example if test 22 fails and you want to know what the test output is, use the following: ctest --verbose -I 22 In case one wishes to see the exact compilation/linking options passed at compile time when using -G "Unix Makefiles": make VERBOSE=1 With -G Ninja the generated build.ninja file shows the build details. libdwarf-code-0.11.1/READMEmacos.md000066400000000000000000000016651472336503500166160ustar00rootroot00000000000000## MacOS builds of libdwarf and dwarfdump Tested on up to date MacOS Ventura September 8, 2023 ## Getting set up Install Mac Command Line Tools from Apple if you do not have compilers installed. Point your browser to macports.org and install the port command by downloading a .pkg file, clicking on the downloaded package, and following the instructions. Close Terminal (if open). Open a terminal window (at this point the port program will be in your $PATH ). sudo port install zlib sudo port install zstd sudo port install meson sudo port select --set python3 python311 port commands install in subdirectories of /opt/local. ## Basic validation At this point normal configure/cmake/meson builds should work and 'make check' works too. From the source directory one can run: sh scripts/allsimplebuilds.sh The full libdwarf-regressiontests suite runs successfully. There is no reason for you to run that testsuite. libdwarf-code-0.11.1/READMEwin-msys2.md000066400000000000000000000123631472336503500173610ustar00rootroot00000000000000# USING MSYS2 (WINDOWS) CMAKE, MESON, CONFIGURE Created 7 October 2023 Updated 19 December 2023 msys2 provides an environment much like posix/unix/linux with programs precompiled for use on windows installed in its own set of locations. Do not use the -DWALL option to cmake or --enable-wall to configure or the meson equivalent as it causes a minor warning about I64u , from gcc (treated as an error). When using configure note that building a static library libdwarf.a is not supported. A static libdwarf.a can be built with meson or cmake. ### Shared library builds Libdwarf builds from configure and cmake are static (archive) library builds by default. Meson builds to a shared library by default. On msys2 with cmake one can generate a shared library build with: -DBUILD_SHARED=YES -DBUILD_NON_SHARED=NO With the following on the meson command line one can build libdwarf as an archive and dwarfdump and the programs built will use the static library. --default-library static The meson default is shared and can be explicitly chosen by: --default-library shared configure will only allow generation of shared library builds, while for cmake and meson one can choose whether to build a shared library or a static (archive) library (libdwarf.a). On msys2 with configure one gets a shared library build with: --enable-shared --disable-static ### NOTE on linking against libdwarf.a If you are are linking code against a static library libdwarf.a you must arrange to define the macro LIBDWARF_STATIC in compiling your code that does a #include "libdwarf.h". To pass LIBDWARF_STATIC to the preprocessor with Visual Studio: right click on a project name In the contextual menu, click on Properties at the very bottom In the new window, double click on C/C++ On the right, click on Preprocessor definitions The is a small down arrow on the right, click on it, then click on Modify Add LIBDWARF_STATIC to the values Click on OK to close the windows ### Building with Visual Studio on Windows While Windows Visual Studio is not a supported environment the following may be of interest to some. Building in Windows Visual Studio is fairly straightforward. We'll use the simplest possible setup (we hope). Using VS buttons and settings do: 1. Main Panel: Click Git. Subpanel: click Clone Repository In the subpanel fill in the clone source: https://github.com/davea42/libdwarf-code and the directory to place the clone. 2. Main Panel: Click Git. Options list: click Cmake Setup. A Folder View panel (should show up) Click on the top-level CMakeLists.txt file. 3. Main Panel: Click Build. Options list: click Build All Expect a few warnings because the source uses Posix rather than Windows-only calls where applicable. A way to eliminate such warnings using VS is to edit CMakeSettings_schema.json 1. Click on Project (top level menu) 2. Click on "CMake Settings for libdwarf" 3. In the settings panel click on "Edit JSON" 4. In the "buildCommandArgs" line 
   Change 
     "buildCommandArgs": ""
   to
     "buildCommandArgs": "-D_CRT_SECURE_NO_WARNINGS"
## Setting up msys2 on Windows We suggest you use meson for msys2 builds. Direct your browser to msys2.org Download a recent .exe from the downloads page. For example msys2-x86_64-20230718.exe Execute it and follow the instructions on msys2.org A straightforward way to use the tests etc in the source is to find the appropriate MSYS2 shell program and put a link to it on the desktop. The Windows list of applications will show MSYS2 and under that category there will be a list of candidates to use. The useful candidates on x86_64 are are MSYS2 MINGW64 The compiler is gcc MSYS2 CLANG64 The compiler is clang the following should get you sufficient files for building and testing all the build mechanisms: basics pacman -Suy pacman -S base-devel git autoconf automake libtool pacman -S mingw-w64-x86_64-python3 pacman -S mingw-w64-x86_64-toolchain pacman -S mingw-w64-x86_64-zlib pacman -S mingw-w64-x86_64-zstd pacman -S mingw-w64-x86_64-doxygen extras for meson/cmake pacman -S mingw-w64-x86_64-meson pacman -S mingw-w64-x86_64-cmake pacman -S mingw-w64-x86_64-python3-pip To create a distribution one needs xz: pacman -S mingw-w64-x86_64-xz to list packages pacman -Q to remove packages pacman -R ## Ninja speed cmake will generate ninja makefiles on mingw by default, add '-G "Unix Makefiles"' to the cmake command line to generate makefiles for gnu make, but we suggest you use "-G Ninja" for speed and clarity.. ## Basic Testing of libdwarf This checks for the existence critical executables such as cmake,meson,and ninja and only runs builds that could work. sh scripts/allsimplebuilds.sh ## Set a Prefix for test installs To get a usable set of executables set a prefix (for cmake, -DCMAKE_INSTALL_PREFIX=$HOME/bin presuming the bin directory is something in your $PATH in msys2. Set an appropriate prefix whichever build tool you use. ninja install cp src/bin/dwarfdump/dwarfdump.conf to $HOME # then dwarfdump.exe # which will give a short message about # No object file provided. In which case # dwarfdump is usable. libdwarf-code-0.11.1/SECURITY.md000066400000000000000000000014721472336503500161010ustar00rootroot00000000000000# Security Policy ## Supported Versions Fixes to vulnerabilities result in the project issuing a new release with the fixes. We do not patch and release an updated version of a previous release. We will fix any vulnerability from any release if and only if the vulnerability still exists in the latest release. | Version | Supported | | ------- | ------------------ | | 0.9.1 | :white_check_mark: | | < 0.9.1 | :white_check_mark: | ## Reporting a Vulnerability One way to report is to add a Issue on the issues page for the project. Another is to email to libdwarf at linuxmail dot org Normally we respond to a report within one day and provide fixes within a day or two. We can provide the new version of the affected source file as a diff or a copy of the fixed source file(s) when that seems appropriate. libdwarf-code-0.11.1/appveyor.yml000066400000000000000000000025401472336503500166750ustar00rootroot00000000000000environment: global: LIBELF_INSTALL_PREFIX: "C:/libelf" matrix: - platform: Win32 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015" CMAKE_OPTIONS: "" - platform: Win32 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015" CMAKE_OPTIONS: "-DBUILD_SHARED=ON" - platform: Win32 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015" CMAKE_OPTIONS: "-DBUILD_SHARED=ON -DBUILD_NON_SHARED=OFF" - platform: x64 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015 Win64" CMAKE_OPTIONS: "" - platform: x64 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015 Win64" CMAKE_OPTIONS: "-DBUILD_SHARED=ON" - platform: x64 CMAKE_GENERATOR_NAME: "Visual Studio 14 2015 Win64" CMAKE_OPTIONS: "-DBUILD_SHARED=ON -DBUILD_NON_SHARED=OFF" configuration: Release install: - git clone https://github.com/dvirtz/libelf.git - cd libelf - git checkout cmake - cmake . -B_build -G "%CMAKE_GENERATOR_NAME%" -DCMAKE_INSTALL_PREFIX=%LIBELF_INSTALL_PREFIX% - cmake --build _build --config %CONFIGURATION% - cmake --build _build --config %CONFIGURATION% --target INSTALL - cd .. build_script: - cmake . -B_build -G "%CMAKE_GENERATOR_NAME%" -DLIBELF_ROOT=%LIBELF_INSTALL_PREFIX% %OPTIONS% - cmake --build _build --config %CONFIGURATION% test_script: - cmake --build _build --config %CONFIGURATION% --target RUN_TESTS libdwarf-code-0.11.1/autogen.sh000066400000000000000000000006231472336503500163030ustar00rootroot00000000000000#!/bin/sh # Generates Makefiles and more. srcdir=`dirname $0` (autoconf --version) < /dev/null > /dev/null 2>&1 || { echo echo "You must have autoconf installed to compile $PROJECT." echo "Download the appropriate package for your distribution," echo "or get the source tarball at ftp://ftp.gnu.org/pub/gnu/" exit 1 } set -e -x autoreconf --warnings=all --install --verbose --force libdwarf-code-0.11.1/bugxml/000077500000000000000000000000001472336503500156025ustar00rootroot00000000000000libdwarf-code-0.11.1/bugxml/README000066400000000000000000000016451472336503500164700ustar00rootroot00000000000000 The files here are for maintaining a list of bugs fixed so html and xml can be posted to prevanders.net and CVE (see cert.org) issues can reference a public database. This is intended mainly for bugs that can result in application crashes as such can represent a vulnerability that can be exploited. Bugs that result simply in errors in output (but no crash) will typically not be mentioned. Bugs in dwarfdump are not vulnerabilities in the same way and at present these do not get CVE identifiers. To update the report with a new bug prepend a copy of data.template to data.txt. Then enter the data available for the new bug. To update the local web page to check it go to /home/davea/web4/gweb and do sh dwarfbugupdate.sh which will use ./readbugs.py here to update the relevant web pages. Carefully follow the existing formats, the parser is very very simple. David Anderson Created: 2016-05-03.

_dwarf_get_loclist_header_start() is not cautious about values in the header being absurdly large. Unclear as yet if this is the problem but it is a potential problem (fixed for next release). 
  Address Sanitizer in gcc reproduces the report.
  In _dwarf_read_loc_section() the simple calculation of
  loc_section_end was wrong, so end-of section was
  incorrect for the local reads.
  With that fixed we get DW_DLE_READ_LITTLEENDIAN_ERROR when
  libdwarf attempts to read off end of section.

 Bug report on sourceforge.net bug list for libdwarf.
 The bad pointer dereference is due to libdwarf
 not noticing that the DWARF in that file is corrupt.
 In addition
 The code was not noticing that it could dereference
 a pointer that pointed out of bounds in the end-sibling-list
 loop.
 
 The example from the bug report (DW201609-001-poc) has
 the same problem.
 dwarfdump now reports DW_DLE_SIBLING_LIST_IMPROPER
 on both test2.o and DW201609-001-poc.

Libdwarf Vulnerabilities

This page provides documentation of known vulnerabilities in libdwarf. We are concerned here with cases where corrupt (by accident or intention) DWARF can cause the library to get a fault (crash) which could expose the calling program to interception by malefactors. Dates (where known) are in ISO extended date format.

Some of the bugs reported here have a CVE assigned, for example CVE-2017-9052. These are reported on cve.org (or possibly the earlier cve.mitre.org). Search with "libdwarf" on cve.org for a list.

Git reference path names refer to object files in the libdwarf regression test base. The test files can be retrieved via anonymous access:
"git clone https://github.org/davea42/libdwarf-regressiontests"

A few bugs refer to https://bugzilla.redhat.com bug system entries and/or https://bugs.chromium.org in addition to showing the names of test files in the regression test base.

Now we do all the tests on the full Dwarf_Unsigned register number(s) and retain the value in the long form everywhere. Fixed 2023-04-15. Once that is fixed there is still a leak found by valgrind. Tht test code fuzz/fuzz_set_frame_all.c does a local malloc and in some cases returned without free-ing it locally. Now that local malloc has the necessary local free.

vulnerability: dereference null pointer

product: libdwarf

description: Crash in libdwarf on dwarf_srcfiles() call. A dereference off a null pointer due to corrupt file numbers not being noticed. Any such crash left an incomplete and misleading stack trace. The large numbers treated as Dwarf_Signed were part of the problem. Now in libdwarf we check Dwarf_Signed for negative values and issue an error if the value less than 0. So later casts to Dwarf_Unsigned work as intended. The libdwarf problems have been in the library for a very long time.

vulnerability: Denial of Service with fuzzed object.

product: libdwarf

description: The fuzzed testcase has at least four major errors which libdwarf did not catch, leading to unpredictable library behavior, possibly including crashing the calling program. Things not noticed before the fix (and now resulting in error being reported): A) The object has just 2 sections, too few to be real. at least 3 sections are needed to contain DWARF information of any kind. B) Section zero has non-zero contents, in violation of the Elf object specification. C) The header says section strings are in section zero (a violation of the Elf specification). D) Section 1 masquerades as .note.gnu.debug-id and the description size is gigantic (as is the section, which fits the description field length).

_dwarf_get_loclist_header_start() is not cautious about values in the header being absurdly large. Unclear as yet if this is the problem but it is a potential problem (fixed for next release). 

  Address Sanitizer in gcc reproduces the report.
  In _dwarf_read_loc_section() the simple calculation of
  loc_section_end was wrong, so end-of section was
  incorrect for the local reads.
  With that fixed we get DW_DLE_READ_LITTLEENDIAN_ERROR when
  libdwarf attempts to read off end of section.

 Bug report on sourceforge.net bug list for libdwarf.
 The bad pointer dereference is due to libdwarf
 not noticing that the DWARF in that file is corrupt.
 In addition
 The code was not noticing that it could dereference
 a pointer that pointed out of bounds in the end-sibling-list
 loop.
 

 The example from the bug report (DW201609-001-poc) has
 the same problem.
 dwarfdump now reports DW_DLE_SIBLING_LIST_IMPROPER
 on both test2.o and DW201609-001-poc.

vulnerability: A specially crafted DWARF section results in a duplicate free() in libdwarf and the calling application will crash.

product: libdwarf

description: In file dwarf_elf_access.c:1071 

 WRITE_UNALIGNED(dbg,target_section + offset,
     &outval,sizeof(outval),reloc_size);

A crafted ELF file may lead to a large offset value, which bigger than the size of target_section heap chunk, then this WRITE_UNALIGNED() function will write the value of &outval out of the heap chunk. offset is a 64bit unsigned int value, so this is more than a heap overflow bug, but also a Out-of-Bound write bug. So WRITE_UNALIGNED() need more strictly checking to prevent this.

In addition, the test code, fuzz/fuzz_die_cu_attrs_loclist.c, called dwarf_highpc_b() with a Dwarf_Die that is uninitialized local variable (hence contents unpredictable).

If a DWARF5 line table header has an invalid FORM for a pathname, the fi_file_name field may be null and printing it via %s can result in referencing memory at address 0, possibly generating segmentation violation or application crash. Now in case of null we provide a fixed string of <no file name> and for the form code we print the value and <unknown form> so there are no unpredictable effects.

_dwarf_get_loclist_header_start() is not cautious about values in the header being absurdly large. Unclear as yet if this is the problem but it is a potential problem (fixed for next release). 
  Address Sanitizer in gcc reproduces the report.
  In _dwarf_read_loc_section() the simple calculation of
  loc_section_end was wrong, so end-of section was
  incorrect for the local reads.
  With that fixed we get DW_DLE_READ_LITTLEENDIAN_ERROR when
  libdwarf attempts to read off end of section.

 Bug report on sourceforge.net bug list for libdwarf.
 The bad pointer dereference is due to libdwarf
 not noticing that the DWARF in that file is corrupt.
 In addition
 The code was not noticing that it could dereference
 a pointer that pointed out of bounds in the end-sibling-list
 loop.
 
 The example from the bug report (DW201609-001-poc) has
 the same problem.
 dwarfdump now reports DW_DLE_SIBLING_LIST_IMPROPER
 on both test2.o and DW201609-001-poc.

Libdwarf Vulnerabilities

This page provides documentation of known vulnerabilities in libdwarf. We are concerned here with cases where corrupt (by accident or intention) DWARF can cause the library to get a fault (crash) which could expose the calling program to interception by malefactors. Dates (where known) are in ISO extended date format.

Some of the bugs reported here have a CVE assigned, for example CVE-2017-9052. These are reported on cve.org (or possibly the earlier cve.mitre.org). Search with "libdwarf" on cve.org for a list.

Git reference path names refer to object files in the libdwarf regression test base. The test files can be retrieved via anonymous access:
"git clone https://github.org/davea42/libdwarf-regressiontests"

A few bugs refer to https://bugzilla.redhat.com bug system entries and/or https://bugs.chromium.org in addition to showing the names of test files in the regression test base.

vulnerability: A specially crafted DWARF section results in a duplicate free() in libdwarf and the calling application will crash.

product: libdwarf

description: In file dwarf_elf_access.c:1071 

 WRITE_UNALIGNED(dbg,target_section + offset,
     &outval,sizeof(outval),reloc_size);

A crafted ELF file may lead to a large offset value, which bigger than the size of target_section heap chunk, then this WRITE_UNALIGNED() function will write the value of &outval out of the heap chunk. offset is a 64bit unsigned int value, so this is more than a heap overflow bug, but also a Out-of-Bound write bug. So WRITE_UNALIGNED() need more strictly checking to prevent this.

 Bug report on sourceforge.net bug list for libdwarf.
 The bad pointer dereference is due to libdwarf
 not noticing that the DWARF in that file is corrupt.
 In addition
 The code was not noticing that it could dereference
 a pointer that pointed out of bounds in the end-sibling-list
 loop.
 

 The example from the bug report (DW201609-001-poc) has
 the same problem.
 dwarfdump now reports DW_DLE_SIBLING_LIST_IMPROPER

_dwarf_get_loclist_header_start() is not cautious about values in the header being absurdly large. Unclear as yet if this is the problem but it is a potential problem (fixed for next release). 

  Address Sanitizer in gcc reproduces the report.
  In _dwarf_read_loc_section() the simple calculation of
  loc_section_end was wrong, so end-of section was
  incorrect for the local reads.
  With that fixed we get DW_DLE_READ_LITTLEENDIAN_ERROR when
  libdwarf attempts to read off end of section.

vulnerability: A carefully corrupted line table can crash calling app

product: libdwarf

description: A carefully crafted object with an invalid line table could cause libdwarf to dereference a pointer reading a single byte outside of the intended .debug_line section and potentially outside of memory visible to the library. A segmentation fault is possible. The code testing for the error was coded incorrectly so an invalid dereference could occur. Now the test code is correct and the error is detected resulting in a normal error return. 

  This should be visible after redhat makes it public.

vulnerability: dwarfdump crashes if the nest of C scopes is too deep

product: dwarfdump

description: An object file where the DIEs depth of nesting exceeds the limit of 800 levels due to corruption or a compiler bug can result in exhausting the die stack array and writing past its end. A segmentation fault is possible. The code at the point of error was not adjusting the array index properly so an invalid dereference could occur. Now the test code is correct and the array overflow is detected resulting in a normal error return. Additional places where this could occur were identified and the proper test added.

vulnerability: Passing null to %s due to corrupt line table header.

product: libdwarf

description: If a DWARF5 line table header has an invalid FORM for a pathname, the fi_file_name field may be null and printing it via %s can result in referencing memory at address 0, possibly generating segmentation violation or application crash. Now in case of null we provide a fixed string of <no file name> and for the form code we print the value and <unknown form> so there are no unpredictable effects.

description: The fuzzed testcase has at least four major errors which libdwarf did not catch, leading to unpredictable library behavior, possibly including crashing the calling program. Things not noticed before the fix (and now resulting in error being reported): A) The object has just 2 sections, too few to be real. at least 3 sections are needed to contain DWARF information of any kind. B) Section zero has non-zero contents, in violation of the Elf object specification. C) The header says section strings are in section zero (a violation of the Elf specification). D) Section 1 masquerades as .note.gnu.debug-id and the description size is gigantic (as is the section, which fits the description field length).

vulnerability: Memory Leak reading experimental line table

product: libdwarf

description: A fuzzed line table in the non-standard (experimental) two-level line table format had several unchecked values and one was larger than made any sense, and detecting the error revealed a memory leak. Caused by the incomplete fix to DW202305-001 (yesterday). This is was a failure to run some crucial tests, which would have exposed the problem before DW202305-001 was completed. Incomplete testing.

description: A call to dwarf_set_frame_undefined_value() dwarf_set_frame_rule_initial_value() dwarf_set_frame_same_value() dwarf_set_frame_cfa_value() dwarf_set_frame_rule_table_size() with unusable values was not being caught. Now if the set of values violates the required relationships an error is returned on requesting actual frame data. The problem has existed for many years (fixed May 23). Once that is fixed valgrind shows leaks. That is because fuzz/fuzz_set_frame_all.c fails to call dwarf_finish() and, instead, simple exit()s at several places. Updated the test source to return from its functions and only exit() from main() after the dwarf_finish() call.

The bug was present when the function was created in 2021 Moreover, oss fuzz originally noted the bug on 02 March 2023 but I can find no trace of a notification of the bug arriving before 24 November 2023. Fixing this sort of thing for all functions, here is the last commit id... ef77596af000719c04bd3e40b97139247ff3efb4

vulnerability: Null dereference from dwarf_gnu_debuglink()

product: libdwarf

description: If the Dwarf_Debug was opened with dwarf_init_object_b() there is no pathname known to libdwarf and the library was dereferencing a null pointer as a result. With the library bug fixed the fuzz/fuzz_debuglink.c test case was violating the rules of use of the function resulting in memory leakage. The documentation has been improved on this function.

vulnerability: Reference memory outside of section.

product: libdwarf

description: The data pointer for DW_FORM_ref1 was not being validated as pointing into the section before being dereferenced. Here reading a corrupted DWARF section. A library crash is likely. This test failure happened to be on a DW_AT_abstract_origin attribute, but the problem applies in many other situations. Nearly the other forms had checks. This check has been missing for many years. Similarly the requisite check was missing from DW_FORM_block1 for many years and that too was fixed so all the FORMs have checks now.

vulnerability: crashes randomly on fuzzed object

product: libdwarf

description: In a multiply-corrupted DWARF object libdwarf may try to dealloc(free) an allocation twice. Results are unpredictable and various. This has been a possibility since we added code to prevent leaks when generating 'unattached' Dwarf_Error records (where there is no Dwarf_Debug available at the point of error). The problem was introduced in libdwarf-0.1.0 in 2021.

STRIP_FROM_PATH = # The STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of the # path mentioned in the documentation of a class, which tells the reader which # header file to include in order to use a class.

TAB_SIZE = 4 # This tag can be used to specify a number of aliases that act as commands in # the documentation. An alias has the form: # name=value # For example adding # "sideeffect=@par Side Effects:^^" # will allow you to put the command \sideeffect (or @sideeffect) in the # documentation, which will result in a user-defined paragraph with heading # "Side Effects:". Note that you cannot put \n's in the value part of an alias # to insert newlines (in the resulting output). You can put ^^ in the value part # of an alias to insert a newline as if a physical newline was in the original # file.

OPTIMIZE_OUTPUT_SLICE = NO # Doxygen selects the parser to use depending on the extension of the files it # parses. With this tag you can assign which parser to use for a given # extension. Doxygen has a built-in mapping, but you can override or extend it # using this tag. The format is ext=language, where ext is a file extension, and # language is one of the parsers supported by doxygen: IDL, Java, JavaScript, # Csharp (C#), C, C++, Lex, D, PHP, md (Markdown), Objective-C, Python, Slice, # VHDL, Fortran (fixed format Fortran: FortranFixed, free formatted Fortran: # FortranFree, unknown formatted Fortran: Fortran. In the later case the parser # tries to guess whether the code is fixed or free formatted code, this is the # default for Fortran type files). For instance to make doxygen treat .inc files # as Fortran files (default is PHP), and .f files as C (default is Fortran), # use: inc=Fortran f=C. # # Note: For files without extension you can use no_extension as a placeholder. # # Note that for custom extensions you also need to set FILE_PATTERNS otherwise # the files are not read by doxygen. When specifying no_extension you should add # * to the FILE_PATTERNS. # # Note see also the list of default file extension mappings. EXTENSION_MAPPING = # If the MARKDOWN_SUPPORT tag is enabled then doxygen pre-processes all comments # according to the Markdown format, which allows for more readable # documentation. See https://daringfireball.net/projects/markdown/ for details. # The output of markdown processing is further processed by doxygen, so you can # mix doxygen, HTML, and XML commands with Markdown formatting. Disable only in # case of backward compatibilities issues. # The default value is: YES. MARKDOWN_SUPPORT = YES # When the TOC_INCLUDE_HEADINGS tag is set to a non-zero value, all headings up # to that level are automatically included in the table of contents, even if # they do not have an id attribute. # Note: This feature currently applies only to Markdown headings. # Minimum value: 0, maximum value: 99, default value: 5. # This tag requires that the tag MARKDOWN_SUPPORT is set to YES. TOC_INCLUDE_HEADINGS = 5 # When enabled doxygen tries to link words that correspond to documented # classes, or namespaces to their corresponding documentation. Such a link can # be prevented in individual cases by putting a % sign in front of the word or # globally by setting AUTOLINK_SUPPORT to NO. # The default value is: YES. AUTOLINK_SUPPORT = YES # If you use STL classes (i.e. std::string, std::vector, etc.) but do not want # to include (a tag file for) the STL sources as input, then you should set this # tag to YES in order to let doxygen match functions declarations and # definitions whose arguments contain STL classes (e.g. func(std::string); # versus func(std::string) {}). This also make the inheritance and collaboration # diagrams that involve STL classes more complete and accurate. # The default value is: NO. BUILTIN_STL_SUPPORT = NO # If you use Microsoft's C++/CLI language, you should set this option to YES to # enable parsing support. # The default value is: NO. CPP_CLI_SUPPORT = NO # Set the SIP_SUPPORT tag to YES if your project consists of sip (see: # https://www.riverbankcomputing.com/software/sip/intro) sources only.

SIP_SUPPORT = NO # For Microsoft's IDL there are propget and propput attributes to indicate # getter and setter methods for a property. Setting this option to YES will make # doxygen to replace the get and set methods by a property in the documentation. # This will only work if the methods are indeed getting or setting a simple # type.

IDL_PROPERTY_SUPPORT = NO # If member grouping is used in the documentation and the DISTRIBUTE_GROUP_DOC # tag is set to YES then doxygen will reuse the documentation of the first # member in the group (if any) for the other members of the group.

SUBGROUPING = YES # When the INLINE_GROUPED_CLASSES tag is set to YES, classes, structs and unions # are shown inside the group in which they are included (e.g. using \ingroup) # instead of on a separate page (for HTML and Man pages) or section (for LaTeX # and RTF). # # Note that this feature does not work in combination with # SEPARATE_MEMBER_PAGES. # The default value is: NO. INLINE_GROUPED_CLASSES = NO # When the INLINE_SIMPLE_STRUCTS tag is set to YES, structs, classes, and unions # with only public data fields or simple typedef fields will be shown inline in # the documentation of the scope in which they are defined (i.e. file, # namespace, or group documentation), provided this scope is documented. If set # to NO, structs, classes, and unions are shown on a separate page (for HTML and # Man pages) or section (for LaTeX and RTF). # The default value is: NO. INLINE_SIMPLE_STRUCTS = NO # When TYPEDEF_HIDES_STRUCT tag is enabled, a typedef of a struct, union, or # enum is documented as struct, union, or enum with the name of the typedef. So # typedef struct TypeS {} TypeT, will appear in the documentation as a struct # with name TypeT. When disabled the typedef will appear as a member of a file, # namespace, or class. And the struct will be named TypeS. This can typically be # useful for C code in case the coding convention dictates that all compound # types are typedef'ed and only the typedef is referenced, never the tag name. # The default value is: NO. TYPEDEF_HIDES_STRUCT = NO # The size of the symbol lookup cache can be set using LOOKUP_CACHE_SIZE. This # cache is used to resolve symbols given their name and scope. Since this can be # an expensive process and often the same symbol appears multiple times in the # code, doxygen keeps a cache of pre-resolved symbols. If the cache is too small # doxygen will become slower. If the cache is too large, memory is wasted. The # cache size is given by this formula: 2^(16+LOOKUP_CACHE_SIZE). The valid range # is 0..9, the default is 0, corresponding to a cache size of 2^16=65536 # symbols. At the end of a run doxygen will report the cache usage and suggest # the optimal cache size from a speed point of view. # Minimum value: 0, maximum value: 9, default value: 0. LOOKUP_CACHE_SIZE = 0 # The NUM_PROC_THREADS specifies the number threads doxygen is allowed to use # during processing.
