* dump_syms: handle forward reference DWARF attributesMark Mentovai2019-12-022-13/+35
| | | | | | | | | | | | | | | | | | | | | | | DW_AT_specification and DW_AT_abstract_origin attributes carry references to other DIEs. Nothing prevents the DIEs referred to from appearing later in .debug_info than the DIE containing the referring attribute, but dump_syms incompletly implemented its handling of these references, and was only able to resolve them when they were back-references. This will fix the chronic warnings produced by dump_syms of the form: dump_syms: the DIE at offset <offset> has a {DW_AT_specification, DW_AT_abstract_origin} attribute referring to the die at offset <offset>, which either was not marked as {a declaration, an inline}, or comes later in the file Patch by Greg Clayton Bug: breakpad:441 Change-Id: I98957d64a234c22afb6d0153f1bdc09e6a600b1d Reviewed-on: https://chromium-review.googlesource.com/c/breakpad/breakpad/+/1946706 Reviewed-by: Mark Mentovai <mark@chromium.org>

| | | | | | | | | | | | | | | | | | 3e56ef9d changed dump_syms to set the module name from DT_SONAME expecting that clients were already using DT_SONAME when it was present. The Breakpad client previously only used DT_SONAME as the name for a module if it detected that it was likely mapped from a zip file. This patch updates the Breakpad Linux client to always use the DT_SONAME in minidumps if it's present. Also included are changes to address comments that were missed from that review.

* linux, dump_syms: Filter module entries outside specified rangesChristopher Grant2019-10-294-0/+120
| | | | | | | | | | | | | | | | | | | | Partitioned libraries generated with lld and llvm-objcopy currently contain a superset of debug information, beyond what applies to the library itself. This is because objcopy cannot split up debug information by partition - instead, it places a copy of all debug information into each partition. In lieu of potential future support for lld or objcopy becoming able to split up debug information, let dump_syms do the next best thing: - Find the address ranges of all PT_LOAD segments in the lib. - Supply these to the Module being generated. - Filter additions to the Module based on these ranges.

* Mac dump_syms: accept __DWARF segment without __debug_info sectionMark Mentovai2019-08-072-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | A .dSYM may validly contain a __DWARF segment without any __debug_info section. This can occur for Chromium Framework in a component build of Chromium, because in that case, all of the code is in other libraries that Chromium Framework depends on. This was previously tested by an assertion, but the assertion did not trigger in NDEBUG (release) builds. In NDEBUG builds, this condition would lead to an out-of-bounds read, detected by AddressSanitizer. Instead of an assertion, the check is now always done at runtime. Instead of being fatal, it's now just a warning, because it's been established that __DWARF without __debug_info can occur. (In the Chromium case, it remains pointless to run dump_syms via the "chrome_dump_syms" target on a component build, as it'll only attempt to symbolize Chromium Framework, and not any of the libraries that Chromium Framework depends on that actually contain the code.)

* string_conversion: fix pointer mathMike Frysinger2019-08-053-2/+67
| | | | | | | | | | | | | | | | | | | | | | | Since target_ptr is of type uint16_t* already, we don't need to scale the byte count as the language does that for us. If it were void*, we would need this code, but it's not. In practice it's probably not a big deal due to how we preallocated memory: when converting UTF8->UTF16, we'd reserve the same number of code units, and UTF8 takes more code units per codepoint than UTF16, so the UTF16 vector is always oversized. When converting UTF32->UTF16, we also reserve the same number of code units, but since one UTF32 code unit could require two UTF16 code units (for U+10000 codepoints and higher), we would probably corrupt memory in the process. The APIs in this module don't seem to take into account that range in general, so for now I'm only fixing the memory corruption.

* Make breakpad_unittests work with Chrome's test runner instead of gtest'sMark Mentovai2019-04-191-0/+6
| | | | | | | | | | | | | | | | | | | Chrome's test runner on Linux installs its own StackDumpSignalHandler which swallows signals and doesn't re-raise them. This is sloppy, but apparently there are reasons (https://crbug.com/551681). For breakpad_unittests, it causes problems where a test process expects (via waitpid()) to observe a child crash. Deal with those cases by explicitly restoring the default signal handler. In another case, Chrome's test runner seems to have been arriving at the conclusion that it was to expect output from a child. Transitioning from exit() to _exit() fixes this problem, and it's not necessarily a bad idea to do this in post-fork() children without an execve() anyway.

* mac dump_syms: Support .dSYMs > 4GB (partially)Mark Mentovai2019-03-282-10/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even 64-bit Mach-O (MH_MAGIC_64 = 0xfeedfacf) is not a fully 64-bit file format. File offsets in sections are stored in 32-bit fields, with Mach-O writers typically truncating offsets too large to fit to just their low 32 bits. When a section begins at a file offset >= 4GB, dump_syms would produce an error such as: Google Chrome Framework.dSYM/Contents/Resources/DWARF/Google Chrome Framework: the section '__apple_names' in segment '__DWARF' claims its contents lie outside the segment's contents As a workaround, this implements the strategy I first described in https://crbug.com/940823#c22. Segment file offsets are stored in 64-bit fields. Because segments contain sections and must load contiguously, it’s possible to infer a section’s actual offset by computing its load address relative to its containing segment’s load address, and treating this as an offset into the containing segment’s file offset. For safety, this is only done for 64-bit segments (LC_SEGMENT_64) where the 32-bit section offset stored in the Mach-O file is equal to the low (truncated) 32 bits of the section offset recomputed per the above strategy. Beware that this does not provide full “large file” support for 64-bit Mach-O files. There are other file offsets within Mach-O files aside from section file offsets that are stored in 32-bit fields even in the 64-bit format, including offsets to symbol table data (LC_SYMTAB and LC_DYSYMTAB). No attempt is made to recover correct file offsets for such data because, at present, such data is always stored by dsymutil near the beginning of .dSYM files, within the first 4GB. If it becomes necessary to address these other offsets, it should be possible to recover these offsets by reference to the __LINKEDIT segment that normally contains them, provided that __LINKEDIT doesn’t span more than 4GB, according to the strategy discussed at the bottom of https://crbug.com/940823#c22. Although this is sufficient to allow dump_syms to interpret Chromium .dSYM files that exceed 4GB, be warned that these Mach-O files are still technically malformed, and most other tools that consume Mach-O files will continue to have difficulties interpreting these large files. As further warning, note that should any individual DWARF section exceed 4GB, internal section offsets will be truncated irrecoverably, unless and until the toolchain implements support for DWARF64. https://bugs.llvm.org/show_bug.cgi?id=14969 With this change, dump_syms is able to correctly recover file offsets from and continue processing a .dSYM file with length 4530593528 (4321MB), whose largest section (__DWARF,__debug_info = .debug_info) has size 0x8d64c0b8 (2262MB), and which contains four sections (starting with __DWARF,__apple_names) beginning at file offsets >= 4GB.

All the code and tests that assumed functions to be contiguous entities has been updated to reflect the change. DW_AT_ranges attributes found in compilation units are parsed but no data is generated for them as it is not currently needed.

Fall back to that in when there is nothing else.

| | | | | | | | | | | | | | | | | | Adds an optional 'm' as the first field in FUNCTION and PUBLIC records to indicate that the address corresponds to more than one symbol. Controls this by a command line flag for now to give symbol file users a chance to update. Also reduces the number of IDiaSymbols retained in memory to one per address. This reduces memory consumption by 8% when processing chrome.dll.pdb. Updates the processor to parse the new optional field.
