3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Benc <jbenc@xxxxxxxxxx>
[ Upstream commit 0a7e22609067ff524fc7bbd45c6951dd08561667 ]
When sending out multicast messages, the source address in inet->mc_addr is
ignored and rewritten by an autoselected one. This is caused by a typo in
commit 813b3b5db831 ("ipv4: Use caller's on-stack flowi as-is in output
route lookups").
