When a helper module is unloaded all conntracks refering to it have their helper pointer NULLed out, leading to lots of races. In most places this can be fixed by proper use of RCU (they do already check for != NULL, but in a racy way), additionally nf_conntrack_expect_related needs to bail out when no helper is present. Also remove two paranoid BUG_ONs in nf_conntrack_proto_gre that are racy and not worth fixing. Signed-off-by: Patrick McHarrdy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net> |
