[PATCH 0/2] wait/ptrace: always assume __WALL if the child is traced

Show all headers | View raw

Damn. I simply do not know what should/can we do. From the change
log:

	And I can only hope that this won't break something.

yet this patch cc's -stable.


Please see the changelog, but in short: this is not a kernel bug
but unlikely we can fix all distributions, so I think we have to
change the kernel.

HOWEVER. With this change __WCLONE and __WALL have no effect for
debugger, do_wait() works as if __WALL is set if the child (natural
or not) is traced.


Jan, Pedro, could you please confirm this won't break gdb? I tried
to look into gdb-7.1, and at first glance gdb uses __WCLONE only
because __WALL doesn't work on older kernels, iow it seems to me
that gdb actually wants __WALL so this change should be fine.


Any other ideas?

Oleg.
