2021-07-02vmxnet3: fix cksum offload issues for tunnels with non-default udp portsRonak Doshi1-2/+20
Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload support") added support for encapsulation offload. However, the inner offload capability is to be restricted to UDP tunnels with default Vxlan and Geneve ports. This patch fixes the issue for tunnels with non-default ports using features check capability and filtering appropriate features for such tunnels.

2021-07-02nfp: flower-ct: remove callback delete deadlockLouis Peens1-13/+0
The current location of the callback delete can lead to a race condition where deleting the callback requires a write_lock on the nf_table, but at the same time another thread from netfilter could have taken a read lock on the table before trying to offload. Since the driver is taking a rtnl_lock this can lead into a deadlock situation, where the netfilter offload will wait for the cls_flower rtnl_lock to be released, but this cannot happen since this is waiting for the nf_table read_lock to be released before it can delete the callback. Solve this by completely removing the nf_flow_table_offload_del_cb call, as this will now be cleaned up by act_ct itself when cleaning up the specific nf_table.

2021-07-01ibmvnic: retry reset if there are no other resetsSukadev Bhattiprolu1-3/+19
Normally, if a reset fails due to failover or other communication error there is another reset (eg: FAILOVER) in the queue and we would process that reset. But if we are unable to communicate with PHYP or VIOS after H_FREE_CRQ, there would be no other resets in the queue and the adapter would be in an undefined state even though it was in the OPEN state earlier. While starting the reset we set the carrier to off state so we won't even get the timeout resets. If the last queued reset fails, retry it as a hard reset (after the usual 60 second settling time).

Cleans the next descriptor to watch (next_to_watch) when cleaning the TX ring. Failure to do so can cause invalid memory accesses. If igb_poll() runs while the controller is reset this can lead to the driver try to free a skb that was already freed. (The crash is harder to reproduce with the igb driver, but the same potential problem exists as the code is identical to igc) Fixes: 7cc6fd4c60f2 ("igb: Don't bother clearing Tx buffer_info in igb_clean_tx_ring") Signed-off-by: Vinicius Costa Gomes <[email protected]> Reported-by: Erez Geva <[email protected]> Tested-by: Tony Brelinski <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>
