David Miller d7f58d5f2c sparc64: Make corrupted user stacks more debuggable. ... [ Upstream commit 5b4fc3882a649c9411dd0dcad2ddb78e911d340e ] Right now if we get a corrupted user stack frame we do a do_exit(SIGILL) which is not helpful. If under a debugger, this behavior causes the inferior process to exit. So the register and other state cannot be examined at the time of the event. Instead, conditionally log a rate limited kernel log message and then force a SIGSEGV. With bits and ideas borrowed (as usual) from powerpc. Signed-off-by: David S.
