There is no need to increment the module refcount again, its enough to obtain one reference per object, i.e. take a reference on object creation and put it on object destruction. Signed-off-by:

Since there is no way for list_for_each_entry_continue() to start interating in the middle of the list they can be replaced with a call to list_for_each_entry(). In preparation to limit the scope of the list iterator to the list traversal loop, the list iterator variable 'rule' should not be used past the loop. v1->v2: - also replace first usage of list_for_each_entry_continue() (Florian Westphal) Signed-off-by:

When hitting the recirculation limit, the kernel would currently log something like this: [ 58.586597] openvswitch: ovs-system: deferred action limit reached, drop recirc action Which isn't all that useful to debug as we only have the interface name to go on but can't track it down to a specific flow. With this change, we now instead get: [ 58.586597] openvswitch: ovs-system: deferred action limit reached, drop recirc action (recirc_id=0x9e) Which can now be correlated with the flow entries from OVS.

The rxrpc_call struct has a timer used to handle various timed events relating to a call. This timer can get started from the packet input routines that are run in softirq mode with just the RCU read lock held. Unfortunately, because only the RCU read lock is held - and neither ref or other lock is taken - the call can start getting destroyed at the same time a packet comes in addressed to that call. This causes the timer - which was already stopped - to get restarted. Later, the timer dispatch code may then oops if the timer got deallocated first. Fix this by trying to take a ref on the rxrpc_call struct and, if successful, passing that ref along to the timer. If the timer was already running, the ref is discarded. The timer completion routine can then pass the ref along to the call's work item when it queues it. If the timer or work item where already queued/running, the extra ref is discarded.

Jason A. Donenfeld says: ==================== wireguard patches for 5.18-rc1 Here's a small set of fixes for the next net push: 1) Pipacs reported a CFI violation in a cleanup routine, which he triggered using grsec's RAP. I haven't seen reports of this yet from the Android/CFI world yet, but it's only a matter of time there. 2) A small rng cleanup to the self test harness to make it initialize faster on 5.18. 3) Wang reported and fixed a skb leak for CONFIG_IPV6=n. 4) After Wang's fix for the direct leak, I investigated how that code path even could be hit, and found that the netlink layer still handles IPv6 endpoints, when it probably shouldn't. ==================== Link: https://lore.kernel.org/r/20220330013127.426620-1-Jason@zx2c4.comSigned-off-by:

The previous commit fixed a memory leak on the send path in the event that IPv6 is disabled at compile time, but how did a packet even arrive there to begin with? It turns out we have previously allowed IPv6 endpoints even when IPv6 support is disabled at compile time. This is awkward and inconsistent. Instead, let's just ignore all things IPv6, the same way we do other malformed endpoints, in the case where IPv6 is disabled. Fixes: e7096c13 ("net: WireGuard secure network tunnel") Signed-off-by:
