Nicolas Dichtel f15ca723c1 net: don't call update_pmtu unconditionally ... Some dst_ops (e.g. md_dst_ops)) doesn't set this handler. It may result to: "BUG: unable to handle kernel NULL pointer dereference at (null)" Let's add a helper to check if update_pmtu is available before calling it. Fixes: 52a589d51f ("geneve: update skb dst pmtu on tx path") Fixes: a93bf0ff44 ("vxlan: update skb dst pmtu on tx path") CC: Roman Kapl <code@rkapl.cz> CC: Xin Long <lucien.xin@gmail.com> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.
