Subject: selinux: Fix check for xfrm selinux context algorithm
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8f82a6880d8d03961181d973388e1df2772a8b24;p=linux-beck.git

selinux: Fix check for xfrm selinux context algorithm

selinux_xfrm_sec_ctx_alloc accidentally checks the xfrm domain of
interpretation against the selinux context algorithm. This patch
fixes this by checking ctx_alg against the selinux context algorithm.
