From: Eric Paris Date: Tue, 23 Nov 2010 06:28:08 +0000 (+0000) Subject: SELinux: indicate fatal error in compat netfilter code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2fe66ec242d3f76e3b0101f36419e7e5405bcff3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
