* Allow minidump_dump to print module lists that would normally be rejectedTed Mielczarek2018-03-121-0/+3
| | | | | | | | | | | | | | | | | for being too long. We've seen some minidumps that fail to process because they contain a ridiculous number of modules (usually due to something leaking shm mappings, it looks like). They're annoying to investigate because even minidump_dump fails to load and print the module list. This patch makes minidump_dump effectively remove the limit on the number of modules it will load, so inspecting the dump by hand is possible.

* Handle very large stack tracesLeonard Mosescu2017-07-1212-78/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main motivation for this change is to handle very large stack traces, normally the result of infinite recursion. This part is actually fairly simple, relaxing a few self-imposed limits on how many frames we can unwind and the max size for stack memory. Relaxing these limits requires stricter and more consistent checks for stack unwinding. There are a number of unwinding invariants that apply to all the platforms: 1. stack pointer (and frame pointer) must be within the stack memory (frame pointer, if preset, must point to the right frame too) 2. unwinding must monotonically increase SP (except for the first frame unwind, this must be a strict increase) 3. Instruction pointer (return address) must point to a valid location 4. stack pointer (and frame pointer) must be appropriately aligned This change is focused on 2), which is enough to guarantee that the unwinding doesn't get stuck in an infinite loop. 1) is implicitly validated part of accessing the stack memory (explicit checks might be nice though). 4) is ABI specific and while it may be valuable in catching suspicious frames is not in the scope of this change. 3) is also an interesting check but thanks to just-in-time compilation it's more complex than just calling StackWalker::InstructionAddressSeemsValid() and we don't want to drop parts of the callstack due to an overly conservative check.

* Added classes to support reading unloaded module lists in minidumps.Joshua Peraza2016-12-164-1/+558
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementations of Module/UnloadedModule and ModuleList/UnloadedModuleList are very similar. They have been made separate classes because they operate on different structs, complicating factoring code into a base class and have sufficiently different implementation that templates would not be suitable. When unloaded modules have partially overlapping ranges, the module shrink down feature is used to move the start of the higher range to the end of the lower range. If two unloaded modules overlap identically, the second module will not be added to the range map and the failure ignored. Places where MinidumpUnloadedModule differs from MinidumpModule: code_identifier: the android/linux case is deleted since cv_records never exist. debug_file/debug_identifier/version: always return empty strings. Read: an expected size is provided as opposed to MD_MODULE_SIZE. A seek is used if there are extra, unused bytes. Places where MinidumpUnloadedModuleList differs from MinidumpModuleList: Read: entry and header size is provided in the header in addition to count. This changes the checks and handling of padding. Failures from StoreRange are ignored. GetMainModule: always returns NULL.
