* Handle very large stack tracesLeonard Mosescu2017-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Peraza2016-12-161-0/+390
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This is a fix for http://crbug/611824. I also found an use-after-free issue (bug in Minidump::SeekToStreamType). I disallowed the MinidumpStreamInfo copy and assign constructors and the compiler detected another similar issue in Minidump::Print. Then I disabled the copy and assign constructors for most classes in minidump.h (just in case). There are a couple of classes where I couldn't disallow them (since assign is used).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes MDCVInfoELF (which is currently unused, apparently a vestigal bit of code landed as part of Solaris support) into a supported CodeView format that simply contains a build id as raw bytes. Modern ELF toolchains support build ids nicely: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Developer_Guide/compiling-build-id.html It would be useful to have the original build ids of loaded modules in Linux minidumps, since tools like Fedora's darkserver allow querying by build id and the current Breakpad code truncates the build id to the size of a GUID, which loses information: https://darkserver.fedoraproject.org/ A follow-up patch will change the Linux minidump generation code to produce MDCVInfoELF in minidumps instead of MDCVInfoPDB70. This patch should be landed first to ensure that crash processors are able to handle this format before dumps are generated containing it. The full build id is exposed as the return value of Minidump::code_identifier(), which currently just returns "id" for modules in Linux dumps. For backwards-compatibility, Minidump::debug_identifier() continues to treat the build id as a GUID, so debug identifiers for existing modules will not change.

* Add support for Linux memory mapping stream and remove ELF header usageLiu.andrew.x@gmail.com2015-07-281-0/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | when checking exploitability rating. Linux minidumps do not support MD_MEMORY_INFO_LIST_STREAM, meaning the processor cannot retrieve its memory mappings. However, it has its own stream, MD_LINUX_MAPS, which contains memory mappings specific to Linux (it contains the contents of /proc/self/maps). This CL allows the minidump to gather information from the memory mappings for Linux minidumps. In addition, exploitability rating for Linux dumps now use memory mappings instead of checking the ELF headers of binaries. The basis for the change is that checking the ELF headers requires the minidumps to store the memory from the ELF headers, while the memory mapping data is already present, meaning the size of a minidump will be unchanged. As a result, of removing ELF header analysis, two unit tests have been removed. Arguably, the cases that those unit tests check do not merit a high exploitability rating and do not warrant a solid conclusion that was given earlier.

| | | | | | | | | | | | | | | | | | | | - Convert time_t values to UTC correctly. It is incorrect to cast a uint32_t* to time_t* because the two types may have different widths. This is the case on many 64-bit systems, where time_t is a 64-bit signed integer. Conversion is unified in a single function, and additional uses of time_t in minidump files not previously displayed in UTC are now displayed. - Interpret the IMAGE_DEBUG_MISC structure correctly. - When printing MINIDUMP_SYSTEM_INFO structures, always show the "x86" side of the union, and state whether it's expected to be valid. (Existing Breakpad-produced non-Windows minidumps for x86_64 use the "x86" side of union, but Windows minidumps for x86_64 use the "other" side, so I want to print both.)
