* android: truncate lower of two overlapping modulesJoshua Peraza2020-02-211-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | Previously, the processor truncated the upper of two overlapping module ranges to compensate for incorrect reporting of module ranges by the Breakpad client. Crashpad correctly reports module load ranges, so this truncation strategy is no longer necessary. However, when partitioned libraries are used, the base library may have a range which encompasses the other partitions. When this is combined with the truncate upper merge strategy, the base library's executable segment is truncated causing symbolization failures. This patch changes Android's merge strategy to truncate the lower range (which is still the base library, but this strategy truncates from the high end of the library's range, instead of its base).

* arm64: strip PACs from link register valuesJoshua Peraza2019-07-232-1/+33
| | | | | | | | | | | | | | | | | | | | | | Pointer authentication codes are used to validate pointers against accidental or malicious modification by storing a hash of the address and a secret value in the pointer's unused, upper bits. The exact bits used may vary by implementation and depend on the size of the virtual address space of the target system, and whether other tagged pointer features are in use. Apple has implemented PACs in the Apple A12. https://developer.apple.com/documentation/security/preparing_your_app_to_work_with_pointer_authentication The documented method of stripping PACs from a pointer is to call ptrauth_strip(), which ultimately emits an `xpaci` instruction, but this option isn't available to the Breakpad processor not running on the device. Instead, this patch selects likely address bits from link register values by examining the address range of loaded modules.

* Enable truncation of module rangesJoshua Peraza2019-06-1110-101/+480
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ELF modules are loaded in memory in several, possibly discontiguous, segments. If the holes between segments are large enough, other things, possibly other ELF modules may be mapped in that space. Crashpad records the range of modules as the base address of the lowest mapped segment to the high address of the highest mapped segment. This means that when one module is mapped into a hole in another, it appears to the Breakpad processor as overlapping modules. Module ranges are relevant to the Breakpad processor during stackwalking for identifying which module a particular program counter belongs to (i.e. mapping the address to a module's text segment). This patch addresses this issue of overlapping modules by truncating the range of the module with the lower base address. A typical module's text segment is the first loaded segment which would leave the text segment range unaffected. Module producers can restrict the size of holes in their ELF modules with the flag "-Wl,-z,max-page-size=4096", preventing other modules from being mapped in their address range. Properly contemplating ELF module address ranges would require extensions to the minidump format to encode any holes. crbug.com/crashpad/298 This patch also renames the concept of "shrinking down" (which truncated the upper of two overlapping ranges) to "truncate upper".

| | | | | | | | | | | | | | Certain minidumps for 32-bit crashes have the upper 32-bit of the crash address (which is a 64-bit value) set to non-zero values.

This patch masks out those bits when reading the raw minidump data to ensure this doesn't happen anymore.

* 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.

| | | | | | | | | | | | | | | The current stack output is one line byte string which is not easy for humans to parse. Extend the print mode to support a hexdump-like view and switch to that by default. Now we get something like: Stack 00000000 20 67 7b 53 94 7f 00 00 01 00 00 00 00 00 00 00 | g{S...........| 00000010 00 70 c4 44 9a 25 00 00 08 65 7a 53 94 7f 00 00 |.p.D.%...ezS...| BUG=chromium:598947 Change-Id: I868e1cf4faa435a14c5f1c35f94a5db4a49b6a6d Reviewed-on: https://chromium-review.googlesource.com/404008 Reviewed-by: Mark Mentovai <mark@chromium.org>
