SubjectRe: [PATCH 2/2] coredump: add a new elf note with siginfo fields of the signal
Date
I agree with Oleg.  If there is an NT_SIGINFO note, it should contain
exactly the siginfo_t layout and data that we otherwise expose to userland
already. That is, it must match what PTRACE_GETSIGINFO reports, which (I
think) also matches exactly what appears on the stack for a signal
delivery. Note also that compat_binfmt_elf must deliver the 32-bit version
of siginfo_t, i.e. as copy_siginfo_to_user32 does.


Thanks,
Roland
