* Fix compilation with gcc --std=c++11ted.mielczarek@gmail.com2015-03-244-9/+9

* Fix compatibility with Android NDK r10d.primiano@chromium.org2015-03-161-15/+0
| | | | | | | | | | | | | | | | This is a reland of the previous CL (r1433). r1433 did not achieve what intended and failed the x86_64 build of Chrome with NDK r10c. The workaround logic in this CL is identical to r1433, but the #define magic is applied in a more appropriate proper place this time. Turns out Breakpad already has an Android compatibility layer, which is common/android/include. Piggybacking the fix there.

* Make breakpad compatible with Android NDK r10d.primiano@chromium.org2015-03-102-5/+16
| | | | | | | | | | | | | | | | | | | | | r1397 did introduce a workaround to deal with a typo in sys/user.h in the Android NDK. The typo has been fixed in [1]. However, breakpad cannot just switch to the fixed version as this would require atomic rolls of Breakpad and NDK in chromium, which would make reverts hard to handle. This change introduces an inelegant yet functional hack which makes breakpad compatible with both versions of the NDK, with and without the typo. It can be reverted once Chrome has stably rolled to NDK r10d.

* Microdump writer: stop using new/malloc in compromised contextprimiano@chromium.org2015-03-101-9/+13
| | | | | | | | | | | | | | | | A recent change in the client-side microdump write (r1404) ended up introducing a call to new() to instantiate the line buffer that microdump uses to dump its lines. new/malloc is a luxury we cannot afford in a compromised context. This change switches the line buffer to be backed by the dumper page allocator, which on Linux/Android ends up requesting pages via mmap. Also, the microdump write bails out without crashing if the page allocator failed (crash during severe OOM). BUG=640 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1432 4c0a9323-5329-0410-9bdc-e9ce6186880e
* 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.

* 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).

* 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.

* First cut at adding arm64 Linux / Android support to Breakpad.rmcilroy@chromium.org2014-04-026-11/+68
| | | | | | | | | | | | | | 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.

* fix races in CrashGenerator::CreateChildCrashvapier@chromium.org2014-04-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* disable unittests under ASAN that use memory crashesvapier@chromium.org2013-12-111-5/+14
| | | | | | | | | | | | | | | | | | | | | There are a bunch of tests that use invalid memory acesses (on purpose) to trigger a crash so that we can detect things are dumped correctly. When we run under ASAN, it catches those accesses and the breaks the testing flow. For now, use the existing ADDRESS_SANITIZER symbol to disable more tests. Ideally we'd use a compile-time attribute to disable ASAN on a few funcs, but that seems to be broken atm.

* Add MMX detection when getting registers in Linux.thestig@chromium.org2013-12-091-2/+11
| | | | | | | | | | | | | | | | For CPUs that don't support the MMX instruction set, such pre-Pentium III or industrial x86 embedded PCs, the minidump fails when it tries to retrieve MMX specific registers. This patch adds MMX detection for that call. Tested on Ubuntu 12.04 with i686, and on a custom Linux distro on a Vortex86DX microcontroller.

* Allow SIGABRT to abort the program.thestig@chromium.org2013-11-071-2/+3
| | | | | | | | | | | | | | | | | | | | SIGABRT can be generated internally, usually by calling abort(), or externally by another process. When the signal is generated by the kernel, info->si_pid is 0 and the signal is treated in the same way as an exception (SIGSEGV, etc.), but the assumption that the exception happens again upon return from the handler is wrong, so we must have a special case for this.
