Subject: SELinux: indicate fatal error in compat netfilter code
X-Git-Url: https://bbs.cooldavid.org/git/?p=net-next-2.6.git;a=commitdiff_plain;h=2fe66ec242d3f76e3b0101f36419e7e5405bcff3;hp=04f6d70f6e64900a5d70a5fc199dd9d5fa787738

SELinux: indicate fatal error in compat netfilter code

The SELinux ip postroute code indicates when policy rejected a packet and
passes the error back up the stack.  The compat code does not.  This patch
sends the same kind of error back up the stack in the compat code.
