* linux_core_dumper: add a fallback definition for NT_SIGINFOMike Frysinger2019-03-072-0/+6
| | | | | | | | | | When building on an old system with outdated headers, this define might not be available. Add a fallback to our existing elf header.

* linux_core_dumper: support NT_SIGINFO for reading crashing addressMike Frysinger2019-03-031-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | The current core dumper only parses NT_PRSTATUS notes. With signal details, this note only includes three fields: signo, code, and errno. We set exception_code to signo and exception_flag to code. The errno value isn't set by the kernel, so there's no need to save it. However, we never fill in exception_address which means all converted crashes look like they happen at address 0. This implies a NULL jump which is usually not the case, so it's just confusing. The prstatus structure doesn't offer anything directly that tracks this. Starting with linux-3.7, the kernel writes out the full siginfo structure in the NT_SIGINFO note. So lets support that to pull out si_addr which, for a bunch of common signals, is the value we want in exception_address. The size of the siginfo_t structure should be locked to 128 bytes at build time for all architectures, so this should hopefully be stable.

* Always emit a 32-bit crash address for 32-bit architecturesGabriele Svelto2019-01-303-8/+56
| | | | | | | | | | | | | | 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 caused a crash address with more than 32-bits to be printed out for minidumps of 32-bit architectures. This patch masks out those bits when reading the raw minidump data to ensure this doesn't happen anymore.
