Subject: ipv4: Conditionally enable transparent flow flag when connecting
X-Git-Tag: v2.6.28-rc1~717^2~154
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=79876874ce20d37ecdc7f481ebf142466999152f;p=profile%2Fivi%2Fkernel-x86-ivi.git

ipv4: Conditionally enable transparent flow flag when connecting

Set FLOWI_FLAG_ANYSRC in flowi->flags if the socket has the
transparent socket option set. This way we selectively enable certain
connections with non-local source addresses to be routed.
