* Use breakpad_getcontext on all Linux platforms missing getcontextMichael Forney2020-03-1614-87/+124
| | | | | | | | | | | | | | | | | | | | getcontext is also not available on musl libc, so generalize breakpad_getcontext so it can be used as a fallback for non-Android platforms as well. On x86_64 and i386, ucontext_t uses an Android-specific offset for storage of FP registers, since its sigset_t differs in size. So, make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET conditional on whether we are building for Android. On glibc and musl, signal.h and asm/sigcontext.h can't be included together, so in breakpad_context_unittest.cc, only compare the libc and kernel _fpstate when on Android.

* 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).

The only problem getting it to build with ndk-build is that the linux_syscall_support.h header is missing. Normally, this header would be downloaded by the depot_tools. But we cannot install depot_tools on our CI machines. So, we would like to include the header as a separate submodule in our repo. The only change we would need to make to breakpad to make that work is to add this optional variable to the C header search path. In the normal case, this variable will not be set and nothing will be different. But we can set the variable to allow us to build without installing depot_tools.

Having uploader.mm depend on GTMLogger causes pain to iOS projects that want to integrate both breakpad and google_toolbox_for_mac. Since the file uploader.mm mixed uses of fprintf and GTMLogger to log errors and warning, convert it to only use fprintf to stderr.

* Revert "Remove use of "register" keyword, deprecated in C++17"Mark Mentovai2019-11-011-1/+1
| | | | | | | | | | | | | | This reverts commit 07411862eaa9a9a38e84caed2e97e836e456656f. We were a bit overzealous in removing “register” here. Both clang and GCC correctly disallow “register” as a storage class specifier in C++17 mode by producing an error in ordinary use. However, they require “register” to be specified for explicit register variables, and do not produce an error in this case.

* linux, client: set module name from DT_SONAMEJoshua Peraza2019-10-302-24/+32
| | | | | | | | | | | | | | | | | | 3e56ef9d changed dump_syms to set the module name from DT_SONAME expecting that clients were already using DT_SONAME when it was present. The Breakpad client previously only used DT_SONAME as the name for a module if it detected that it was likely mapped from a zip file. This patch updates the Breakpad Linux client to always use the DT_SONAME in minidumps if it's present. Also included are changes to address comments that were missed from that review.

* linux, dump_syms: Filter module entries outside specified rangesChristopher Grant2019-10-294-0/+120
| | | | | | | | | | | | | | | | | | | | Partitioned libraries generated with lld and llvm-objcopy currently contain a superset of debug information, beyond what applies to the library itself. This is because objcopy cannot split up debug information by partition - instead, it places a copy of all debug information into each partition. In lieu of potential future support for lld or objcopy becoming able to split up debug information, let dump_syms do the next best thing: - Find the address ranges of all PT_LOAD segments in the lib. - Supply these to the Module being generated. - Filter additions to the Module based on these ranges.

* linux, dump_syms: set module name from DT_SONAMEJoshua Peraza2019-10-244-44/+78
| | | | | | | | | | | | | The Breakpad and Crashpad clients will use an object's DT_SONAME as the name for a module if it exists. Previously, linux dump_syms would assume the basename of an input elf file matches that value, causing symbol lookups to fail if they were mismatched. This patch updates dump_syms to use DT_SONAME as the module name, if present.

* Mac dump_syms: accept __DWARF segment without __debug_info sectionMark Mentovai2019-08-072-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | A .dSYM may validly contain a __DWARF segment without any __debug_info section. This can occur for Chromium Framework in a component build of Chromium, because in that case, all of the code is in other libraries that Chromium Framework depends on. This was previously tested by an assertion, but the assertion did not trigger in NDEBUG (release) builds. In NDEBUG builds, this condition would lead to an out-of-bounds read, detected by AddressSanitizer. Instead of an assertion, the check is now always done at runtime. Instead of being fatal, it's now just a warning, because it's been established that __DWARF without __debug_info can occur. (In the Chromium case, it remains pointless to run dump_syms via the "chrome_dump_syms" target on a component build, as it'll only attempt to symbolize Chromium Framework, and not any of the libraries that Chromium Framework depends on that actually contain the code.)
