Subject: [PATCH net 0/3] sctp: a bunch of fixes by holding transport
Date: Fri, 28 Oct 2016 10:10:51 +0000 [thread overview]
Message-ID: <cover.1477649076.git.lucien.xin@gmail.com> (raw)
There are several places where it holds assoc after getting transport by
searching from transport rhashtable, it may cause use-after- free issue.
This patchset is to fix them by holding transport instead.
Xin Long (3):
sctp: hold transport instead of assoc in sctp_diag
sctp: return back transport in __sctp_rcv_init_lookup
sctp: hold transport instead of assoc when lookup assoc in rx path
