* [microdump] Add build fingerprint and product info metadata.primiano@chromium.org2015-05-156-50/+163
| | | | | | | | | | | | | | | | This is to add build fingerprint and product name/version to microdumps. Conversely to what happens in the case of minidumps with MIME fields, due to the nature of minidumps, extra metadata cannot be reliably injected after the dump is completed. This CL adds the plumbing to inject two optional fields plus the corresponding tests.

* Fix signal propagation logic for Linux/Android exception handler.primiano@chromium.org2015-04-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code is relying on info->si_pid to figure out whether the exception handler was triggered by a signal coming from the kernel (that will re-trigger until the cause that triggered the signal has been cleared) or from user-space e.g., kill -SIGNAL pid, which will NOT automatically re-trigger in the next signal handler in the chain. While the intentions are good (manually re-triggering user-space signals), the current implementation mistakenly looks at the si_pid field in siginfo_t, assuming that it is coming from the kernel if si_pid == 0. This is wrong. siginfo_t, in fact, is a union and si_pid is meaningful only for userspace signals. For signals originated by the kernel, instead, si_pid overlaps with si_addr (the faulting address). As a matter of facts, the current implementation is mistakenly re-triggering the signal using tgkill for most of the kernel-space signals (unless the fault address is exactly 0x0). This is not completelly correct for the case of SIGSEGV/SIGBUS. The next handler in the chain will stil see the signal, but the |siginfo| and the |context| arguments of the handler will be meaningless (retriggering a signal with tgkill doesn't preserve them). Therefore, if the next handler in the chain expects those arguments to be set, it will fail. Concretelly, this is causing problems to WebView. In some rare circumstances, the next handler in the chain is a user-space runtime which does SIGSEGV handling to implement speculative null pointer managed exceptions (see as an example http://www.mono-project.com/docs/advanced/runtime/docs/exception-handling/) The fix herein proposed consists in using the si_code (see SI_FROMUSER macros) to determine whether a signal is coming form the kernel (and therefore just re-establish the next signal handler) or from userspace (and use the tgkill logic). Repro case: This issue is visible in Chrome for Android with this simple repro case: - Add a non-null pointer dereference in the codebase: *((volatile int*)0xbeef) = 42 Without this change: the next handler (the libc trap) prints: F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x487 where 0x487 is actually the PID of the process (which is wrong). With this change: the next handler prints: F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0xbeef which is the correct answer.

| | | | | | | | | | | | | | | | | | | | | | | The current processor implementation is grepping for /google-breakpad( in the logcat lines, to filter out microdump lines, which by default look like this: W/google-breakpad( 3728): -----BEGIN BREAKPAD MICRODUMP----- Turns out that logcat format can vary, when passing optional arguments, and produce something like the following: 04-13 12:30:35.563 6531 6531 W google-breakpad: -----BEGIN ...

* Fix compatibility with Android NDK r10d.primiano@chromium.org2015-03-162-17/+20
| | | | | | | | | | | | | | | | 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).

* 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).

* Update breakpad to support Android NDK r10cprimiano@chromium.org2014-10-213-445/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
