* Add debug fission support.Yunlian Jiang2016-05-041-1/+2
| | | | | | | | | | | | | | | | | | | | | 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. (replace .debug with .dwp) BUG=chromium:604440 R=dehao@google.com, ivanpe@chromium.org Review URL: https://codereview.chromium.org/1884283002 .

* Added an option (-i) to have dump_syms output header information only.David Yen2016-04-082-18/+77
| | | | | | | | | | | | | | | | | 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 Mielczarek2016-04-054-129/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. This change keeps the debug ID in the `dump_syms` output the same to match. R=mark@chromium.org, thestig@chromium.org BUG= Review URL: https://codereview.chromium.org/1688743002 .

* Have dump_syms output the full symbol table.David Yen2016-03-231-18/+47
| | | | | | | | | | | | | | | | | | Some of the symbols in the stack trace are not found in the .dynsym section but were located in the full symbol table .symtab section instead. This was causing some of our stack traces to be incomplete or point to incorrect function names. Since we only output function names, there are actually not that many more symbols located in .symtab that aren't in .dynsym. It is better to simply output all symbols found so our stack traces are complete. R=mark@chromium.org, thestig@chromium.org BUG=561447 Review URL: https://codereview.chromium.org/1824063002 .

* Update breakpad for Android packed relocations.rmcilroy@chromium.org2015-06-191-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | Shared libraries containing Android packed relocations have a load bias that differs from the start address in /proc/$$/maps. Current breakpad assumes that the load bias and mapping start address are the same. Fixed by changing the client to detect the presence of Android packed relocations in the address space of a loaded library, and adjusting the stored mapping start address of any that are packed so that it contains the linker's load bias. For this to work properly, it is important that the non-packed library is symbolized for breakpad. Either packed or non-packed libraries may be run on the device; the client detects which has been loaded by the linker.

| | | | | | | | | | | | | | | | | | | | | | APK file. This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive): - Do not filter mappings which map an executable at a non-zero offset. - If such an executable is mapped look in the ELF information for the shared object name and use that name in the minidump. Note this change doesn't care about the archive format and isn't Android specific (though loading the shared library this way is currently only done on Android).

| | | | | | | | | | | | | | After r1299, the LinuxCoreDumperTest::VerifyDumpWithMultipleThreads and ElfCoreDumpTest::ValidCoreFile would both hang on Android.

This assumption isn't always true as the kernel skips filling the NT_FPREGSET / NT_PRXFPREG note of a thread if the FPU state isn't available. The kernel indicates the availability of NT_FPREGSET / NT_PRXFPREG via the pr_fpvalid field of the NT_PRSTATUS note.

* fix races in CrashGenerator::CreateChildCrashvapier@chromium.org2014-04-022-14/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current CreateChildCrash logic is racy when it comes to creating a crash dump for two reasons: The main thread that calls kill() on a different thread is guaranteed the signal will be *queued* when it returns, but not *delivered*. If the kernel doesn't automatically schedule the receiving thread, but instead lets the main thread run to the exit() call, then the signal never triggers a coredump and the whole process simply exits. The main thread is using kill() to try to deliver a signal to a specific thread, but that function is for sending signals to a process. That means the kernel is free to deliver the signal to any thread in the process and not just the one requested. This manifests itself as the pr_pid in the coredump not being the one expected. Instead, we must use tkill() with the tid (which we already took care of gathering) to deliver to a specific thread. These are a lot easier to see on a UMP system as contention is heavier.

Looking at p_offset for this isn't correct, and the first segment doesn't have p_offset == 0 here because NaCl can't map the ELF file headers as part of the first segment (which is for validatable code only).

* Improve ARM CPU info reporting.digit@chromium.org2013-04-243-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves several things for Linux/ARM: - Better detection of the number of CPUs on the target device. The content of /proc/cpuinfo only matches the number of "online" CPUs, which varies over time with recent Android devices. - Reconstruct the CPUID and ELF hwcaps values from /proc/cpuinfo, this is useful to better identify target devices in minidumps. - Make minidump_dump display the new information in useful ways. - Write a small helper class to parse /proc/cpuinfo and also use it for x86/64. - Write a small helper class to parse sysfds cpu lists. - Add a my_memchr() implementation. - Add unit tests. Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs) and a Nexus 4 (4 CPUs).
