Subject: [PATCH 0/1] exec: do not sleep in TASK_TRACED under ->cred_guard_mutex
Date: Thu, 3 Sep 2009 18:05:10 +0200	[thread overview]
Message-ID: <20090903160510.GA23638@redhat.com> (raw)

I cc'ed Linus and stable, but I don't know how to really test this patch
and I don't really understand the new creds management.

Please review.


load_flat_shared_library() does something strange (but hopefully this
patch doesn't break it). I do not understand why does it create the
new bprm. Afaics, it could reuse bprm pointer which comes as an argument
of ->load_binary(), all we need is to temporary change/restore bprm->file
for load_flat_file().

Oleg.
