| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MINIDUMP_MISC_INFO_N structure. Added the necessary code for swapping and string conversion from UTF-16. Found and fixed a bug in MinidumpAssertion::Read where the max string length passed to UTF16codeunits was in bytes instead of UTF-16 chars. Tested with a minidump containing a version 3 structure to validate the string conversion routines. Interestingly enough the time_zone names does not appear to be abbreviation as the documentation was suggesting but full names, e.g. Eastern Standard Time: MDRawMiscInfo size_of_info = 232 flags1 = 0xf7 process_id = 0x54c4 process_create_time = 0x51a9323c process_user_time = 0x1 process_kernel_time = 0x0 processor_max_mhz = 3100 processor_current_mhz = 1891 processor_mhz_limit = 3100 processor_max_idle_state = 0x1 processor_current_idle_state = 0x1 The new fileds follow: process_integrity_level = 0x1000 process_execute_flags = 0x4d protected_process = 0 time_zone_id = 2 time_zone.bias = 300 time_zone.standard_name = Eastern Standard Time time_zone.daylight_name = Eastern Daylight Time Review URL: https://breakpad.appspot.com/617002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1204 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | errors and use the good data if possible. More specifically: - Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report. - Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen. - In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates. - Added and updated unittests. Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this: ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | doesn't see the correct thread stack memory. Instead, it loads garbage (from offset 0 of the minidump file - well that's not garbage, but it is not the stack memory region either) and attempts to walk it. A typical symptom of this issue is when you get a single stack frame after processing - the context frame - for which you don't need stack memory. This issue is caused by an invalid RVA in the memory descriptor stored inside the MINIDUMP_THREAD structure for the thread. Luckily, the invalid RVA is 0, and the start_of_memory_region appears to be correct, so this issue can be easily detected and the correct memory region can be loaded using an RVA specified in the MinidumpMemoryList. I couldn't find a reasonable description on MSDN regarding MINIDUMP_MEMORY_DESCRIPTOR.MINIDUMP_LOCATION_DESCRIPTOR having RVA of 0 except maybe for full dumps where the 64-bit version of the structure (MINIDUMP_MEMORY_DESCRIPTOR64) is used and it has no RVA at all. It has a 64-bit DataSize which if interpreted as the 32-bit structure will very likely result in 0 for the RVA: http://msdn.microsoft.com/en-us/library/windows/desktop/ms680384(v=vs.85).aspx Anyways, the dump that I looked at was not a full dump so 0 for RVA is a bit puzzling (at least easily detectable): ...

| | | | | | | | | | | | | (or not in a known module). This is achieved by: 1. Extending the span of the scan for return address in the conext frame. Initially, I wanted to extend the span of the scan for all frames but then I noticed that there is code for ARM already that is extending the search only for the context frame. This kind of makes sense so I decided to reuse the same idea everywhere. 2. Attempting to restore the EBP chain after a successful scan for return address so that the stackwalker can switch back to FRAME_TRUST_CFI for the rest of the frames when possible. I also fixed the lint errors in the files touched.

* Breakpad: Support DWARF CFI-driven stack walking on ARM.jimblandy2010-03-161-11/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the Breakpad minidump processor to use data from STACK CFI records to generate stack traces for the ARM processor. In the symbol dumper, we need a table mapping DWARF CFI register numbers to their names: STACK CFI records refer to registers by name. In the processor, we expand StackwalkerARM::GetCallerFrame to see if there are STACK CFI records covering the callee, and then use those to recover the caller's register values. There's no good reason the ARM walker couldn't use the SimpleCFIWalker interface declared in cfi_frame_info.h. Unfortunately, that interface assumes that one can map register names to member pointers of the raw context type, while MDRawContextARM uses an array to hold the registers' values: C++ pointer-to-member types can't refer to elements of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters in StackwalkerARM::GetCallerFrame. We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for convenience in referring to certain ARM registers with dedicated purposes, like the stack pointer and the PC. We define validity flags in StackFrameARM for all the registers, since CFI could theoretically recover any of them. In the same vein, we expand minidump_stackwalk.cc to print the values of all valid callee-saves registers in the context --- and use the proper names for special-purpose registers. We provide unit tests that give full code and branch coverage (with minor exceptions). We add a testing interface to StackwalkerARM that allows us to create context frames that lack some register values. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@553 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy2010-03-163-12/+28
| | | | | | | | | | | | | | | | | | | | | | | | Add a CFIFrameInfo class (named for symmetry with WindowsFrameInfo) to represent the set of STACK CFI rules in effect at a given instruction, and apply them to a set of register values. Provide a SimpleCFIWalker class template, to allow the essential CFI code to be shared amongst the different architectures. Teach BasicSourceLineResolver to partially parse 'STACK CFI' records, and produce the set of rules in effect at a given instruction on demand, by combining the initial rule set and the appropriate rule deltas in a CFIFrameInfo object. Adapt StackwalkerX86 and StackFrameX86 to retrieve, store, and apply CFI stack walking information. Add validity flags for all the general-purpose registers to StackFrameX86::ContextValidity. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@549 4c0a9323-5329-0410-9bdc-e9ce6186880e
