* Add debug fission support.Yunlian Jiang2016-05-0410-105/+2183
| | | | | | | | | | | | | | | | | | | | | This added debug fission support. It tries to find the dwp file from the debug dir /usr/lib/debug/*/debug and read symbols from them. Most of this patch comes from https://critique.corp.google.com/#review/52048295 and some fixes after that. The elf_reader.cc comes from TOT google code. I just removed some google dependency. Current problems from this patch 1: Some type mismatch: from uint8_t * to char *. 2: Some hack to find the .dwp file.

* Write adjusted range back to moduleTao Bai2016-05-032-0/+13
| | | | | | | | | | | | | | | | | In Android, the mmap could be overlapped by /dev/ashmem, we adjusted the range in https://breakpad.appspot.com/9744002/, but adjusted range isn't written back to module, this caused the corresponding module be dropped in BasicCodeModules copy constructor.

* Revert of Extend mapping merge to include reserved but unused mappings. ↵Primiano Tucci2016-04-281-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (https://breakpad.appspot.com/7714003) Reason for revert: It is causing breakpad crash reports to be invalid (see the associated bug). Merging empty holes in r-x mappings was originally introduced in https://breakpad.appspot.com/7714003 to deal with the first generation of relro packing, which could introduce holes within a .so mapping: [libchrome.so] [guard region] [libchrome.so] However, the logic is broken for the case of two *different* adjacent .so mappings with a guard region in the middle: [libfoo.so] [guard region] [libchrome.so] In this case the guard region is mistakenly associated with libfoo.so, but that is not the right thing to do. In fact, the second generation of rerlo packing added the guard region to prevent mmaps from overlapping and to give room for the non-zero vaddr of relro-packed libraries, which require an anticipated load bias. As the first generation of relro packing is not used anymore, there is no reason to keep this buggy code, which causes failures in decoding crashes where an arbitrary library is mapped immediately before a rerlo packed library.

* Make x86-64 frame pointer unwinding stricterTed Mielczarek2016-04-192-51/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The x86-64 frame pointer-based unwind method will accept values that aren't valid for the frame pointer register and the return address. This fixes it to reject non-8-byte-aligned frame pointers, as well as non-canonical addresses for the return address it finds. A colleague of mine asked me why Breakpad gave a bad stack for a crash in our crash-stats system: https://crash-stats.mozilla.com/report/index/a472c842-2c7b-4ca7-a267-478cf2160405 Digging in, it turns out that the function in frame 0 is a leaf function, so MSVC doesn't generate an entry in the unwind table for it, so dump_syms doesn't produce a STACK CFI entry for it in the symbol file. The stackwalker tries frame pointer unwinding, and %rbp is set to a value that sort-of works, so it produces a garbage frame 1 and then is lost. Either of the two checks in this patch would have stopped the stackwalker from using the frame pointer. It's possible we could do something smarter on the dump_syms side, like enumerating all functions and outputing some default STACK CFI rule for those that don't have unwind info, but that wouldn't fix crashes from existing builds without re-dumping symbols for them. In any event, these checks should always pass for valid frame pointer-using functions.

* Fix DWARF handling of inlined functions in namespacesTed Mielczarek2016-04-142-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently an inlined function in a namespace in DWARF will be given a name comprised of just `namespace::`. This is due to a logic error in ComputeQualifiedName, where it doesn't handle an empty `unqualified_name` properly. We apparently have a fair number of these in our Mac builds, an example of the DWARF that's being mishandled looks like: 0x117eda40: TAG_namespace [5] * AT_name( "js" ) AT_decl_file( "../../dist/include/js/Utility.h" ) AT_decl_line( 35 ) 0x11808500: TAG_subprogram [251] * AT_low_pc( 0x0000000002f12110 ) AT_high_pc( 0x0000000002f1216b ) AT_APPLE_omit_frame_ptr( 0x01 ) AT_frame_base( rsp ) AT_abstract_origin( {0x0000000011800a4f}"_ZN2js40TraceManuallyBarrieredGenericPointerEdgeEP8JSTracerPPNS_2gc4CellEPKc" ) AT_MIPS_linkage_name( "_ZN2js40TraceManuallyBarrieredGenericPointerEdgeEP8JSTracerPPNS_2gc4CellEPKc" ) AT_name( "TraceManuallyBarrieredGenericPointerEdge" ) AT_decl_file( "/builds/slave/rel-m-rel-m64_bld-000000000000/build/js/src/gc/Marking.cpp" ) AT_decl_line( 547 ) AT_external( 0x01 ) AT_APPLE_optimized( 0x01 ) AT_inline( DW_INL_inlined ) This turned a few instances of this in the file I was testing on into `<name omitted>`, which seems to just be a symptom of the "DW_AT_abstract_origin comes later in the file" issue. (Which is probably also worth fixing given that it occurs some 29k times when dumping symbols from Firefox's XUL binary, but it's a separate issue.)

* Add some new stream types to MDStreamTypeTed Mielczarek2016-04-132-0/+12
| | | | | | | | | | | | | | I ran minidump_dump on a dump from Firefox on my Windows 10 machine and noticed some streams that Breakpad didn't have names for. Looking in minidumpapiset.h in the Windows 10 SDK finds these values in MINIDUMP_STREAM_TYPE. There are also struct definitions for the stream data for some of them (all but JavaScriptData), but I don't have a particular need for those currently.

* Added an option (-i) to have dump_syms output header information only.David Yen2016-04-086-83/+188
| | | | | | | | | | | | | | | | | It is often helpful to check if a particular symbol file dumped by dump_syms actually matches a version of a binary file we have. The symbol output contains an ID which can be used to see if it matches the binary file. Unfortunately, this ID is internally calculated and not a standard hash of the binary file. Being able to output the header information only will allow users to determine whether their symbol file is up to date or not.

* Switch the Linux minidump writer to use MDCVInfoELF for CV data.Ted Mielczarek2016-04-0514-224/+452
| | | | | | | | | | | | | | | | | | | | | | | | | | This preserves full build ids in minidumps, which are useful for tracking down the right version of system libraries from Linux distributions. The default build id produced by GNU binutils' ld is a 160-bit SHA-1 hash of some parts of the binary, which is exactly 20 bytes: https://sourceware.org/binutils/docs-2.26/ld/Options.html#index-g_t_002d_002dbuild_002did-292 The bulk of the changes here are to change the signatures of the FileID methods to use a wasteful_vector instead of raw pointers, since build ids can be of arbitrary length. The previous change that added support for this in the processor code preserved the return value of `Minidump::debug_identifier()` as the current `GUID+age` treatment for backwards-compatibility, and exposed the full build id from `Minidump::code_identifier()`, which was previously stubbed out for Linux dumps.

| | | | | | | | | | | | | | | | | | | | | Currently EXC_BAD_ACCESS doesn't support EXC_I386_GPFLT as exception_flags for pretty-printing in the processor, but this happens for a lot of things: http://opensource.apple.com/source/xnu/xnu-2050.24.15/osfmk/i386/trap.c (search for EXC_I386_GPFLT).

This was causing some of our stack traces to be incomplete or point to incorrect function names.

* Explicitly call non-sized delete on dynamically sized memory for correct ↵Ivan Penkov2016-03-111-1/+1
| | | | | | | | | | | | | | | | behavior under sized-delete. The code as it stands allocates a chunk of memory of arbitrary size and places an object into it. It stores a pointer to that object and memory into a list telling the compiler that it is a pointer to a char. When the compiler deletes the objects in the list it thinks that the list contains pointers to chars - not pointers to arbitrarily sized regions of memory. This is fixing an issue that will reproduces when the following optimization (C++ sized dealocation) is enabled: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2013/n3536.html The fix is to explicitly call the non-sized delete operator, and the library code that supports malloc/free/new/delete will figure out the size of the block of memory from the pointer being passed in.

| | | | | | | | | | | | | | | | If the Linux minidump writer crashes while writing a dump, the dump might contain some useful information, but the header will be empty because TypedMDRVA's destructor flushes the data, and the header var doesn't go out of scope until the end of the `Dump` method. This fixes that problem by putting the header in a shorter block scope.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes MDCVInfoELF (which is currently unused, apparently a vestigal bit of code landed as part of Solaris support) into a supported CodeView format that simply contains a build id as raw bytes. Modern ELF toolchains support build ids nicely: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Developer_Guide/compiling-build-id.html It would be useful to have the original build ids of loaded modules in Linux minidumps, since tools like Fedora's darkserver allow querying by build id and the current Breakpad code truncates the build id to the size of a GUID, which loses information: https://darkserver.fedoraproject.org/ A follow-up patch will change the Linux minidump generation code to produce MDCVInfoELF in minidumps instead of MDCVInfoPDB70. This patch should be landed first to ensure that crash processors are able to handle this format before dumps are generated containing it. The full build id is exposed as the return value of Minidump::code_identifier(), which currently just returns "id" for modules in Linux dumps. For backwards-compatibility, Minidump::debug_identifier() continues to treat the build id as a GUID, so debug identifiers for existing modules will not change.

* Improvements to GYP buildPavel Labath2016-01-293-3/+10
| | | | | | | | | | | | | | | | | | | | | | This updates the GYP build for the processor component (on windows). - adds/removes references to files which were added or removed from the repository - includes build/common.gypi in the gyp files: needed to correctly detect the OS (I think, the generated MSVC solutions were broken without it) - conditionally compiles code platform-specific code for the given platform After this minidump processor nearly compiles with VS2013: the generated project is correct, but some files still have compilation errors. Disclaimer: I have not tested the GYP changes on non-windows platform, as there does not seem to be anyone using it there.

* convert to uint8_t* for binary data to fix -Wnarrowing build errorsMike Frysinger2016-01-2616-173/+219
| | | | | | | | | | | | | | | Newer gcc versions default to -Werror=narrowing when using newer C++ standards (which we do). This causes issues when we try to stuff a value like 0xea into a char -- the value is out of range for signed char bytes.

| | | | | | | | | | | | | | | | | | | | This reverts CL https://codereview.chromium.org/1563223004/ This reverts commit 7cc0d8562bf8b20b88cc941ba72593cb7230ecf6. CL 1563223004 introduces two bugs on iOS. - Encoding the minidump name with extra percent causing crash server to fail processing the file. - Using a released pointer causing random crashes on upload. The data, resp, err pointers returned in the NSURLSession completion handler is released at the end of the block. When used later (to get the crash ID), it causes a crash.
