* Add an optional root prefix to Linux dumpersDominik Laskowski2016-03-071-2/+3
| | | | | | | | | | | The Linux dumpers use absolute paths for shared libraries referenced by dumps, so they fail to locate them if the crash originated in a chroot. This CL enables callers to specify a root prefix, which is prepended to mapping paths before opening them. BUG=chromium:591792 TEST=make check Review URL: https://codereview.chromium.org/1761023002/
* [MIPS]: Use mcontext_t structure for MIPSrmcilroy@chromium.org2015-04-211-11/+16
| | | | | | | | | | | | | | This change removes user_regs_struct and user_fpregs_struct structures for mips and uses mcontext_t instead.

* Handle failures of copying process data from a core file.benchan@chromium.org2015-02-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Chrome on Android now supports loading the shared library directly from the ↵rmcilroy@chromium.org2014-07-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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).

* First cut at adding arm64 Linux / Android support to Breakpad.rmcilroy@chromium.org2014-04-021-1/+3
| | | | | | | | | | | | | | This is an initial attempt to add Arm64 (aarch64) support to Breakpad for Linux / Android platforms. This CL adds the Arm64 data structures, but does not yet implement the Android getcontext support or CPUFillFromThreadInfo / CPUFillFromUContext.

* Don't bail if a thread's stack pointer is invalidmkrebs@chromium.org2012-10-081-3/+2
| | | | | | | | | | | | | | Currently, if a thread's stack pointer is not within a valid memory page, the minidump writing will fail with an error. This change allows an invalid stack pointer by simply setting the memory size to zero in the minidump. The processing code already checks for the size being zero, although it currently just gives an error (see https://breakpad.appspot.com/413002/).

* Implement core dump to minidump conversion.benchan@chromium.org2012-01-191-0/+234
This patch is part of a bigger patch that helps merging the breakpad code with the modified version in Chromium OS. Specifically, this patch makes the following changes: 1. Turn the LinuxDumper class into a base class and move ptrace related code into a new derived class, LinuxPtraceDumper. 2. Add a LinuxCoreDumper class, which is derived from LinuxDumper, to extract information from a crashed process via a core dump file instead of ptrace. 3. Add a WriteMinidumpFromCore function to src/client/linux/minidump_writer/minidump_writer.h, which uses LinuxCoreDumper to extract information from a core dump file. 4. Add a core2md utility, which simply wraps WriteMinidumpFromCore, for converting a core dump to a minidump. BUG=455 TEST=Tested the following: 1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6. 2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock). 3. All unit tests pass. 4. Run Chromium OS tests to test core2md. Review URL: http://breakpad.appspot.com/343001 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@905 4c0a9323-5329-0410-9bdc-e9ce6186880e
