I was about to point that out, but then I noticed that this
doesn't actually fix 19e4e768064a8 ("ipv4: Fix raw socket lookup for
local traffic"), it's just related as it fixes the same issue in
another (very likely) path in the same function.

I think this should have been:
	Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

I *guess* for -stable purposes the effect is the same.
