[release/7.0] Fix multiple dumps from being generated - #80708
Merged
Conversation
Issue: #78956 After a core dump is generated because of a unhandled managed exception abort() is called but a SIGSEGV is generated in libpthread.so which is caught by the runtime and a second core dump is generated. The fix is to uninstall/uninitialize all the signal handlers, not just SIGABORT.

Customer Impact
This issue affects both 1st and 3rd party customers.
The issue (#78956) is that in certain Linux Kubernetes container configurations, 2 core dumps are created: one from the unhandled managed exception and one incorrectly from a SIGSEGV during abort() during process shutdown.
This also fixes hang during unhandled exception processing on ARM64 docker containers (issue #66707).
The soluation is that all the signals that the runtime hooks need to be unregistered before calling the Linux abort() API in the unhandled exception/crash dump generation path.
Testing
Diagnostics/createdump tests ran locally.
Risk
Low. Affects only crash dump generation on Linux/MacOS.
