Subject: [PATCH] net sched: text ematch: zero out ts_state before using it
Date: Thu,  9 Oct 2014 09:05:21 -0700	[thread overview]
Message-ID: <1412870721-31061-1-git-send-email-osandov@osandov.com> (raw)

textsearch_find zeroes out the offset, but the control buffer (which may or may
not matter in this case) needs to be zeroed out as well.
