3.6.11.7-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Neil Horman [ Upstream commit c5c7774d7eb4397891edca9ebdf750ba90977a69 ] In commit 2f94aabd9f6c925d77aecb3ff020f1cc12ed8f86 (refactor sctp_outq_teardown to insure proper re-initalization) we modified sctp_outq_teardown to use sctp_outq_init to fully re-initalize the outq structure. Steve West recently asked me why I removed the q->error = 0 initalization from sctp_outq_teardown. I did so because I was operating under the impression that sctp_outq_init would properly initalize that value for us, but it doesn't. sctp_outq_init operates under the assumption that the outq struct is all 0's (as it is when called from sctp_association_init), but using it in __sctp_outq_teardown violates that assumption. We should do a memset in sctp_outq_init to ensure that the entire structure is in a known state there instead.
