* Cleanup Linux debug link file handling code.thestig@chromium.org2015-02-101-44/+74

* Fix overflow error in breakpad for linuxmark@chromium.org2015-02-051-4/+4
| | | | | | | | | | | | | | | A computation in the stack unwind algorithm could cause an overflow if a base pointer read from crashed process is sufficiently close to top of address space. This causes a memory read that causes the dump thread to crash, resulting in a failure to generate crash dump. Check fixed to properly detect that this pointer is greater than actual memory range of current stack.

* Handle failures of copying process data from a core file.benchan@chromium.org2015-02-026-16/+31
| | | | | | | | | | | | | | | | | | | | | | | | | When LinuxCoreDumper fails to copy process data from a core file, it fills the return buffer with a repeated sequence of a special marker. However, MinidumpWriter doesn't know about that and may incorrectly interpret the data. In many cases, MinidumpWriter simply copies the gibberish data to the minidump, which isn't too bad. However, the gibberish data may cause MinidumpWriter to behave badly in some other cases. For example, when MinidumpWriter tries to iterate through the linked list of all loaded DSOs via the r_map field of a r_debug struct, if the linked list is filed with the special marker, the code keeps iterating through the same address. This CL addresses the issue by having LinuxCoreDumper::CopyFromProcess() returns a Boolean value to indicate if the expected data is found from the core file. MinidumpWriter can then decide how to handle that. BUG=chromium:453484 TEST=Run core2md with the test data attached to chromium:453484.

* Breakpad: Fix build with new clang versions.mark@chromium.org2014-12-102-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc has a single exception setting for all languages. Saying -fno-exceptions in gcc disables exceptions and cleanups for cc files, but has no effect for mm files. In clang, -fno-exceptions only disables c++ exceptions, but keeps objective-c exceptions and cleanups enabled. http://llvm.org/viewvc/llvm-project?view=revision&revision=220714 changed __EXCEPTIONS to be defined for clang when cleanups are enabled, independent of if c++ exceptions are enabled. (This was necessary to have clang work with glibc which looks at __EXCEPTIONS to decide if cleanups are enabled.) Breakpad tried to use __EXCEPTIONS to figure out if c++ exceptions are enabled. In cc files, this works: -fno-exceptions will disable c++ exceptions and cleanups. But in mm files, -fno-exceptions will disable c++ exceptions and objective-c exceptions will still be enabled, and so cleanups must run and hence __EXCEPTIONS is defined. To make things work with both old and new compilers, do the try/catch hack in mm files either if __EXCEPTIONS is not defined (for old compilers) or if the compiler is clang and __has_feature(cxx_exceptions) isn't set (which will work for new clangs too, and which cleanly maps to if c++ exceptions are enabled).

* dump_syms: Fix handling of DW_FORM_ref_addr to work with DWARF 4mseaborn@chromium.org2014-12-031-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, dump_syms did not handle DW_FORM_ref_addr if it appeared in DWARF 4 debugging info. Also fix a DW_FORM_ref_addr case so that it doesn't fall through to the next switch case when assertions are disabled and the DWARF version isn't recognised. The following steps will reproduce the problem when using LLVM 3.4: cat <<END >example1.c int main() { return 0; } END cat <<END >example2.c void foo(int x) {} END clang -emit-llvm -g -c example1.c -o example1.bc clang -emit-llvm -g -c example2.c -o example2.bc llvm-link-3.4 example1.bc example2.bc -o combined.bc clang combined.bc -o executable ./google-breakpad/build/src/tools/linux/dump_syms/dump_syms executable When using LLVM bitcode linking in this way, LLVM's backend generates partially-merged DWARF debugging info in which some of the references to the "int" type go via "DW_FORM_ref_addr". Since PNaCl uses LLVM bitcode linking, this dump_syms failure occurs with nexes produced by the PNaCl toolchain.

* Introduce microdump writer class.primiano@chromium.org2014-10-287-21/+490
| | | | | | | | | | | | | | | | | | | Microdumps are a very lightweight variant of minidumps. They are meant to dump a minimal crash report on the system log (logcat on Android), containing only the state of the crashing thread. This is to deal with cases where the user has opted out from crash uploading but we still want to generate meaningful information on the device to pull a stacktrace for development purposes. Conversely to conventional stack traces (e.g. the one generated by Android's debuggerd or Chromium's base::stacktrace) microdumps do NOT require unwind tables to be present in the target binary. This allows to save precious binary size (~1.5 MB for Chrome on Arm, ~10 MB on arm64).

| | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to NDK r10c, Breakpad was privately backporting these system headers. This change is now unforking and removing those headers and using the ones from the NDK. Rationale: - They are finally available in the NDK, so there is no need to keep maintaining a fork (which was necessary up until recently to support arm64). - These forked headers, as they are today, are not compatible with the latest NDK (i.e. this change is required to roll NDK r10c). The forked ucontext.h, being removed by this CL, depends on some transitional features which are not compatible with the NDK release being targeted here. After this change, the NDK r10c is now required to build Breakpad on Android. Note that NDK releases are backwards compatible and contain all the previous API levels, so this change is NOT effectively enforcing to build against any particular Android SDK.

* Microdumps: refactor out common parts of minidump_writer.ccprimiano@chromium.org2014-10-0110-619/+993
| | | | | | | | | | | | | | | | | | | | This change is a pure refactoring of the common bits of minidump_writer.cc that will be shared soon with the upcoming microdump_writer.cc. In particular, this CL is extracting the following classes: - ThreadInfo: handles the state of the threads in the crashing process. - RawContextCPU: typedef for arch-specific CPU context structure. - UContextReader: Fills out a dump RawContextCPU structure from the ucontext struct provided by the kernel (arch-dependent). - SeccompUnwinder: cleans out the stack frames of the Seccomp sandbox on the supported architectures. - MappingInfo: handles information about mappings BUG=chromium:410294 R=mmandlis@chromium.org Review URL: https://breakpad.appspot.com/4684002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1388 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Extend mapping merge to include reserved but unused mappings.rmcilroy@chromium.org2014-09-191-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parsing /proc/pid/maps, current code merges adjacent entries that refer to the same library and where the start of the second is equal to the end of the first, for example: 40022000-40025000 r-xp 00000000 b3:11 827 /system/lib/liblog.so 40025000-40026000 r--p 00002000 b3:11 827 /system/lib/liblog.so 40026000-40027000 rw-p 00003000 b3:11 827 /system/lib/liblog.so When the system linker loads a library it first reserves all the address space required, from the smallest start to the largest end address, using an anonymous mapping, and then maps loaded segments inside that reservation. If the loaded segments do not fully occupy the reservation this leaves gaps, and these gaps prevent merges that should occur from occurring: 40417000-4044a000 r-xp 00000000 b3:11 820 /system/lib/libjpeg.so > 4044a000-4044b000 ---p 00000000 00:00 0 4044b000-4044c000 r--p 00033000 b3:11 820 /system/lib/libjpeg.so 4044c000-4044d000 rw-p 00034000 b3:11 820 /system/lib/libjpeg.so Where the segments that follow this gap do not contain executable code the failure to merge does not affect breakpad operation. However, where they do then the merge needs to occur. Packing relocations in a large library splits the executable segment into two, resulting in: 73b0c000-73b21000 r-xp 00000000 b3:19 786460 /data/.../libchrome.2160.0.so > 73b21000-73d12000 ---p 00000000 00:00 0 73d12000-75a90000 r-xp 00014000 b3:19 786460 /data/.../libchrome.2160.0.so 75a90000-75c0d000 rw-p 01d91000 b3:19 786460 /data/.../libchrome.2160.0.so Here the mapping at 73d12000-75a90000 must be merged into 73b0c000-73b21000 so that breakpad correctly calculates the base address for text. This change enables the full merge by also merging anonymous maps which result from unused reservation, identified as '---p' with offset 0, and which follow on from an executable mapping, into that executable mapping.
