Subject: ipv6: fix exthdrs offload registration in out_rt path
X-Git-Tag: v4.3-rc1~96^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e41b0bedba0293b9e1e8d1e8ed553104b9693656;p=platform%2Fkernel%2Flinux-exynos.git

ipv6: fix exthdrs offload registration in out_rt path

We previously register IPPROTO_ROUTING offload under inet6_add_offload(),
but in error path, we try to unregister it with inet_del_offload(). This
doesn't seem correct, it should actually be inet6_del_offload(), also
ipv6_exthdrs_offload_exit() from that commit seems rather incorrect (it
also uses rthdr_offload twice), but it got removed entirely later on.

Fixes: 3336288a9fea ("ipv6: Switch to using new offload infrastructure.")
