* linux, dump_syms: set module name from DT_SONAMEJoshua Peraza2019-10-243-1/+78
| | | | | | | | | | | | | The Breakpad and Crashpad clients will use an object's DT_SONAME as the name for a module if it exists. Previously, linux dump_syms would assume the basename of an input elf file matches that value, causing symbol lookups to fail if they were mismatched. This patch updates dump_syms to use DT_SONAME as the module name, if present.

* 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.

* Avoid skipping an initializer with a gotoBruce Dawson2017-10-261-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | C++ doesn't allow skipping initialization with a goto. This means that this code is illegal: void func(bool b) { if(b) goto END; int value = 0; //error C2362 with /permissive- //... value used here END: return; } Adding an extra scope makes the code legal. This problem is only detected with /permissive- but now that compiling with this switch is practical we might as well stay /permissive- clean: https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/ Note that compiling /permissive- clean only works with the 10.0.16299.0 SDK which currently has other issues...

* Rename src/common/memory.h to memory_allocator.h.Ted Mielczarek2017-10-176-9/+9
| | | | | | | | | | | | memory.h shadows a system header which normally isn't a problem because of the include paths in Breakpad, but the Firefox build system winds up with src/common in the include path so we've had a workaround for this for years. Renaming the file lets us get rid of that workaround and shouldn't hurt anything.

* android: Don’t compete with NDK API >= 21 over NDK structuresMark Mentovai2017-09-182-39/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chrome uses API 16 for 32-bit builds and API 21 for 64-bit builds. The NDK’s <link.h> provides r_debug and link_map structure definitions only at API 21 and above. Breakpad used a custom <link.h> to define these structures only during 64-bit builds, which worked for Chrome’s purposes. However, other consumers may wish to build Breakpad at arbitrary API levels without regard to bitness. This alters Breakpad’s custom <link.h> to correctly check the NDK API level rather than target CPU bitness. Likewise for <sys/user.h> on 32-bit x86, which provided a typedef for user_fpxregs_struct to user_fxsr_struct. API 21 and above, as well as the unified headers at any API level, always name the structure user_fpxregs_struct. Definitions for 64-bit ARM’s user_regs_struct and user_fpsimd_struct have been removed from Breakpad’s copy of <sys/user.h>. The header claims that these fallback definitions are only necessary with NDK r10, which should no longer be in use even by Chromium, which now uses NDK r12b. This removes the Chromium-specific ANDROID_NDK_MAJOR_VERSION macro from use entirely. Fixes https://stackoverflow.com/questions/44141159/ and b/65630828.

* Parse DWARF 4 line tables correctlyMark Mentovai2017-09-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Breakpad’s DWARF line table reader only understood line tables at the level of DWARF 2. This wasn’t a problem because LLVM only produced line tables at this level, even when generating DWARF 4. But LLVM would like to output DWARF 4 line tables when generating DWARF 4, and Breakpad needs to understand this format. (Meanwhile, it seems that GCC has used DWARF 4 line tables with DWARF 4 output since 4.5.0, 2010-04-14.) DWARF 3 line tables are fully compatible with DWARF 2 (assuming that nothing needs “prologue end,” “epilogue begin,” or “isa”, and opcodes related to these fields are properly skipped). DWARF 4 changes the line number program header slightly to include a “maximum operations per instruction” field. This field must be recognized, but can safely be ignored (and assumed to be always 1) if VLIW architectures are not supported (they aren’t). DWARF 4 also introduces a “discriminator”, whose opcode can also be skipped if these values are not needed (they shouldn’t be). This recognizes the “maximum operations per instruction” field when processing DWARF 4 line tables, but asserts that its value is 1 and otherwise ignores it. This is not compatible with VLIW architectures that set this field to a value other than 1. Such architectures are irrelevant to Breakpad, and mainline GCC and the proposed LLVM patch always set this field to 1. There are other things that could be extracted from DWARF 3 and 4 line tables that aren’t currently extracted (although these are currently irrelevant to Breakpad too).
