* Teach the ELF parser to handle multiple PT_NOTE phdrs.Peter Collingbourne2017-05-264-38/+76

* Fix race in ExceptionHandler::GenerateDump()Lars Volker2017-05-101-3/+9
| | | | | | | | | | | | | | | | | | | | | When writing a minidump on Linux, we called clone() in linux/handler/exception_handler.cc with the CLONE_FILES flag. If the parent process died while the child waited for the continuation signal, the write side of the pipe 'fdes' stayed open in the child. The child would not receive a SIGPIPE and would wait forever. To fix this, we clone without CLONE_FILES and then close the read-side of fdes in the master before the ptrace call. That way, if the master dies, the child will receive a SIGPIPE and will die, too. To test this I added a sleep() call before SendContinueSignalToChild() and then killed the master, manually observing that the child would die, too.

Relax this test so it correctly handles the case where the expected 256 bytes around the IP aren't at the start of the minidump memory region. Alternatively, that could be avoided by reserving the page before the page used for this test, in which case this test is degenerate with InstructionPointerMemoryMinBound and can be removed.

* Handle ntdll only emitting PUBLIC at func entryScott Graham2017-02-233-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This handles a case encountered in ntdll.dll symbols for Windows 7, where a PUBLIC would be emitted only for the entry point to the function. The body of the function, however, is split in a PGO-ish fashion to another remote location in the binary. Because of this, there were large gaps in the RVA space that would be attributed to the "last" function that happened to have an entry point before the gap. In practice, something like this: 0x100 Func1 0x110 Func2 0x120 Func3 0x130 Func4 ... 0x800 LaterFuncs The bodies of Func1/2/3 tend to be implemented as a fast-path check, followed by a jmp to somewhere in the range between 0x130 and 0x800. Because no symbols are emitted for this range, everything is attributed to Func4, causing crash misattribution. In this CL, the change is: after emitting the entry point symbol, also walk in the original OMAP entries through the untranslated binary, and for each block until we resolve to a new symbol (via the same mechanism as we found the entry point) emit another PUBLIC indicating that there's another block that belongs to that symbol. This effectively breaks up the "0x130 - 0x800" range above.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The address space of every Android Java process is approximately 50% mapped, which means that sanitization tends to be ineffective because most string fragments are plausibly pointers into some mapping. For example, the zygote on 32 bit devices has the following mappings made by dalvik and this covers all 4 byte strings starting with a character between 0x13 and 0x52 (which includes all uppercase characters up to and including 'R'). 12c00000-12d16000 12d16000-32c00000 32c00000-32c01000 32c01000-52c00000 In order to perform stack unwinding we only need pointers into the stack of the thread in question, and pointers to executable mappings. If we reduce the set of considered mappings to those mappings alone, then only ~2% of the address space is left unelided.

* There is no need to use the main queue just for perform selector.George Kola2017-02-131-34/+31
| | | | | | | | | | | | | | | | | | | | | | | | | We were using the main queue to queue up a perform selector and then the code [self sendStoredCrashReports] was immediately doing a dispatch_async. This unnecessary thread switching is not needed. We simplify the above logic and use dispatch_after to queue the block on the internal queue after a delay Note that main queue is typically more loaded and it is better for non-UI code to not use the main queue. This may also help improve crash log upload. This change also switches from @synchronized to dispatch_once as that is faster Reference: http://googlemac.blogspot.com/2006/10/synchronized-swimming.html BUG= Change-Id: I81035149cbbf13a3058ca3a11e6efd23980f19ad Reviewed-on: https://chromium-review.googlesource.com/441364 Reviewed-by: Joshua Peraza <jperaza@chromium.org>
* Appveyor CI for Windows MSVS buildJon Turney2017-02-131-0/+45
| | | | | | | | | | | | | | | | | | | | | | Add a .gyp file for building all windows tools, and add hook to run gyp to create corresponding .sln files. This doesn't try to build for platform:x64. This fails due to various errors caused by the assumption that size_t can be converted to an unsigned int without loss of information, which is not true on Windows x64 (LLP64), where size_t is 64 bits, but int is only 32 bits. There are test failures. client_tests failures are as described in [1]. dump_syms_unittest are as discussed in the description of [2].
