3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Greg Kroah-Hartman <gre...@linuxfoundation.org>
This reverts commit c2f5b7507ac5d808f29287d77ee6148358d7fbfe which is
commit f6e80abeab928b7c47cc1fbf53df13b4398a2bec.
Michal writes:
Mainline commit f6e80abe was introduced in v3.7-rc2 as a
follow-up fix to commit
edfee033 sctp: check src addr when processing SACK to update
transport state
(from v3.7-rc1) which changed the interpretation of third
argument to sctp_cmd_process_sack() and sctp_outq_sack(). But as
commit edfee033 has never been backported to stable branches,
backport of commit f6e80abe actually breaks the code rather than
fixing it.
