Re: [Crash-utility] [PATCH v4] Use register value in elf note NT_PRSTATUS to do backtrace
----- Original Message -----
I also slightly modified the patches to get_netdump_regs_x86() and
get_netdump_regs_x86_64() to avoid the goto's, but with no functional
changes.
Queued for crash version 5.1.5.
Thanks,
Dave
One other thing -- out of sheer paranoia, I've also added this to the
end of read_dump_header():
dd->flags &= ~(DISKDUMP_LOCAL|KDUMP_CMPRS_LOCAL);
+ pc->flags2 &= ~ELF_NOTES;
return FALSE;
}
That will prevent any potential problems with your patch to
x86_64_get_dumpfile_stack_frame():
} else if (ELF_NOTES_VALID()) {
user_regs = bt->machdep;
ur_rip = ULONG(user_regs +
OFFSET(user_regs_struct_rip));
ur_rsp = ULONG(user_regs +
OFFSET(user_regs_struct_rsp));
}
All of the other places that you use ELF_NOTES_VALID(), you
also check DISKDUMP_DUMPFILE().
