ch_ktls: do not send snd_una update to TCB in middle

2021-04-15T23:55:49Z

snd_una update should not be done when the same skb is being sent out.chcr_short_record_handler() sends it again even though SND_UNA update is already sent for the skb in chcr_ktls_xmit(), which causes mismatch in un-acked TCP seq number, later causes problem in sending out complete record.

ch_ktls: tcb close causes tls connection failure

2021-04-15T23:55:49Z

HW doesn't need marking TCB closed. This TCB state change sometimes causes problem to the new connection which gets the same tid.

ch_ktls: fix device connection close

2021-04-15T23:55:49Z

When sge queue is full and chcr_ktls_xmit_wr_complete() returns failure, skb is not freed if it is not the last tls record in this skb, causes refcount never gets freed and tls_dev_del() never gets called on this connection.

ch_ktls: Fix kernel panic

2021-04-15T23:55:49Z

Taking page refcount is not ideal and causes kernel panic sometimes. It's better to take tx_ctx lock for the complete skb transmit, to avoid page cleanup if ACK received in middle.

i40e: fix the panic when running bpf in xdpdrv mode

2021-04-15T21:37:35Z

Fix this panic by adding more rules to calculate the value of @rss_size_max which could be used in allocating the queues when bpf is loaded, which, however, could cause the failure and then trigger the NULL pointer of vsi->rx_rings. Prio to this fix, the machine doesn't care about how many cpus are online and then allocates 256 queues on the machine with 32 cpus online actually. Once the load of bpf begins, the log will go like this "failed to get tracking for 256 queues for VSI 0 err -12" and this "setup of MAIN VSI failed". Thus, I attach the key information of the crash-log here.

net/mlx5e: fix ingress_ifindex check in mlx5e_flower_parse_meta

2021-04-14T23:13:00Z

In the nft_offload there is the mate flow_dissector with no ingress_ifindex but with ingress_iftype that only be used in the software. So if the mask of ingress_ifindex in meta is 0, this meta check should be bypass.

net/mlx5: Fix setting of devlink traps in switchdev mode

2021-04-14T23:12:54Z

Prevent setting of devlink traps on the uplink while in switchdev mode. In this mode, it is the SW switch responsibility to handle both packets with a mismatch in destination MAC or VLAN ID. Therefore, there are no flow steering tables to trap undesirable packets and driver crashes upon setting a trap.
