Re: [patch 1/8] signal: Prevent exec() race

[Oleg Nesterov]

Thomas, I can't read this series today, will try on Weekend.

But you didn't reply to
https://lore.kernel.org/all/apgHJj0qH7HlAXKO@xxxxxxxxxx/
Let me quote that email here:

	OK... lets suppose the exiting task T passes exit_signals().

	Suppose we have an "ignored" timer tmr. Another sub-thread calls
	do_sigaction() -> posixtimer_sig_unignore() and finds that tmr
	in ->ignored_posix_timers list.

	But posixtimer_queue_sigqueue() doesn't check PF_EXITING, I guess
	it should check it too?

	Or perhaps it makes more sense to check PF_EXITING in
	posixtimer_get_target() ?

and at first glance it seems that this version doesn't differ in this respect?

Sorry if I missed something (again ;) but I'd better ask just in case.

Oleg.
