* 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.

* Revert "Fix deprecatation warning when building for recent SDKs on iOS/OS X."Olivier Robin2016-01-212-62/+10
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | This works around a bug in M that prevents Breakpad from using ftruncate() in the renderer process. To do this, skip the calls to ftruncate() when allocating bigger minidump files and strictly depends on write() to append to the end. It might be less efficient but this is probably less of an issue on SD cards. It is much better than not getting crash reports.

* Increasing the Breakpad stack walker max scan limit from 30 to 40.Ivan Penkov2015-10-054-6/+6
| | | | | | | | | | | | | | | | | | | | | Chrome started hitting some crashes in v8 jitted code which happens to be non ABI compliant and debuggers (including WinDBG) are unable to produce meaningful stack traces. The Breakpad stack walker has some builtin heuristics to deal with such cases. More specifically, when unable to find a good parent frame, it scans the raw stack to find a suitable parent frame. The max scan size was set at 30 pointers which was (apparently) not enough to recover in this case. I'm increasing it to 40 pointers. I confirmed that at 34 pointers it was able to recover however I'm setting it to 40 in order to it some slack. I needed to update two unittests which were expecting the previous scan limit.

* Linux ExceptionHandler: don't allocate the CrashContext on the stackPrimiano Tucci2015-09-221-15/+27
| | | | | | | | | | | | | | | | | | | | | | | | | On Android the size of the alternate stack can be very small (8k). Even if breakpad uses sigaltstack to increase the size of the alternate stack during initialization, that call affects only the main thread. On Android, the libc's pthread initializer reset the sigaltstack to 8k. When entering a signal handler, the kernel typically pushes the context on the alternate stack. On arm64, sizeof(CrashContext) is ~5k, which leaves 3k of usable stack for breakpad. On top of that, breakpad allocates another struct CrashContext on the stack. In the case of Android arm64, then, breakpad ends up using 5k + 5k > 8k of stack, which causes a stack overflow. This got unnoticed in Android L, as the alternate stack didn't have red-zones between them, so breakpad was often happily overflowing onto the next thread's stack. This is not the case anymore [1]. This CL moves the CrashContext into a global variable. It should be safe as the ExceptionHandlers are serialized on a mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're working on building our Firefox Mac builds as a Linux cross-compile (https://bugzilla.mozilla.org/show_bug.cgi?id=921040) and we need symbol dumping to work. This change ports the Mac dump_syms tool to build and work on Linux. I've tested it and it produces identical output to running the tool on Mac. The bulk of the work here was converting src/common/mac/dump_syms.mm and src/tools/mac/dump_syms/dump_syms_tool.mm from ObjC++ to C++ and removing their use of Foundation classes in favor of standard C/C++. This won't compile out-of-the-box on Linux, it requires some Mac system headers that are not included in this patch. I have those tentatively in a separate patch to land in Gecko (http://hg.mozilla.org/users/tmielczarek_mozilla.com/mc/rev/5fb8da23c83c), but I wasn't sure if you'd be interested in having them in the Breakpad tree. We could almost certainly pare down the set of headers included there, I didn't spend too much time trying to minimize them (we primarily just need the Mach-O structs and a few associated bits). I just realized that this patch is missing updating the XCode project files (ugh). I'll fix that up in a bit.

| | | | | | | | | | | | | | | If a crash occurred as a result to a write to unwritable memory, it is reason to suggest exploitability. The processor checks for a bad write by disassembling the command that caused the crash by piping the raw bytes near the instruction pointer through objdump. This allows the processor to see if the instruction that caused the crash is a write to memory and where the target of the address is located.

* Remove obsolete seccomp_unwinder for legacy (pre-BPF) sandboxprimiano@chromium.org2015-08-184-214/+0
| | | | | | | | | | | | | | | | | | | | | The PopSeccompStackFrame was introduced to deal with stack frames originated in the legacy seccomp sandbox. The only user of that sandbox was Google Chrome, but the legacy sandbox has been deprecated in 2013 (crrev.com/1290643003) in favor of the new bpf sandbox. Removing this dead code as it has some small bound checking bug which causes occasional crashes in WebView (which are totally unrelated to the sandbox). Note: this will require a corresponding change in the chromium GYP/GN build files to roll.

* [microdump] Move microdump writes to the crash ring-buffer logprimiano@chromium.org2015-08-174-3/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the microdump_writer dumped the log in logcat using the default system log. This is simple to achieve but has some drawbacks: 1. Creates spam in the system log, pushing back other eventual useful messages. 2. There is a high chance that the microdump gets lost if some log spam storm happens immediately after a crash and before the log is collected by the feedback client. 3. Since Android L, the logger is smartly throttling messages (to reduce logcat spam). Throttling brekpad logs defeats the all point of microdumps. This change is conceptually very simple. Replace the use of __android_log_write() with __android_log_buf_write(), which takes an extra bufID argument. The main drawback is that the __android_log_buf_write is not exported in the NDK and needs to be dynamically looked up via dlsym. This choice has been discussed and advocated by Android owners. See the internal bug b/21753476.

* [microdump] Fix hw architecture indication in build fingerprint lineprimiano@chromium.org2015-08-172-15/+60
| | | | | | | | | | | | | | | | r1456 introduced the possibility to customize the OS-line of the microdump, enabling to replace, in the case of android, the generic uname() info with the Android build fingerprint. While doing that, it mistakenly removed the HW architecture indication from the format. See crbug.com/520075 for more details.
