Several state changes occur during SMC socket closing. Currently state changes triggered locally occur in process context with lock_sock() taken while state changes triggered by peer occur in tasklet context with bh_lock_sock() taken. bh_lock_sock() does not wait till a lock_sock(() task in process context is finished. This may lead to races in socket state transitions resulting in dangling SMC-sockets, or it may lead to duplicate SMC socket freeing. This patch introduces a closing worker to run all state changes under lock_sock(). Signed-off-by:

If peer indicates write_blocked, the cursor state of the received data should be send to the peer immediately (in smc_tx_consumer_update()). Afterwards the write_blocked indicator is cleared. If there is no free slot for another write request, sending is postponed to worker smc_tx_work, and the write_blocked indicator is not cleared. Therefore another clearing check is needed in smc_tx_work(). Signed-off-by:

SMC requires an active ib port on the RoCE device. smc_pnet_find_roce_resource() determines the matching RoCE device port according to the configured PNET table. Do not return the found RoCE device port, if it is not flagged active. Signed-off-by:

The global event handler is created only, if the ib_device has already been used by at least one link group. It is guaranteed that there exists the corresponding entry in the smc_ib_devices list. Get rid of this superfluous check. Signed-off-by:

BPF helper functions access socket fields through skb->sk. This is not set in ingress cgroup and socket filters. The association is only made in skb_set_owner_r once the filter has accepted the packet. Sk is available as socket lookup has taken place. Temporarily set skb->sk to sk in these cases. Signed-off-by:

There's no need to have struct bpf_map_type_list since it just contains a list_head, the type, and the ops pointer. Since the types are densely packed and not actually dynamically registered, it's much easier and smaller to have an array of type->ops pointer. Also initialize this array statically to remove code needed to initialize it. In order to save duplicating the list, move it to the types header file added by the previous patch and include it in the same fashion. Signed-off-by:

There's no point in checking for duplicate sessions at the beginning of l2tp_nl_cmd_session_create(); the ->session_create() callbacks already return -EEXIST when the session already exists. Furthermore, even if l2tp_session_find() returns NULL, a new session might be created right after the test. So relying on ->session_create() to avoid duplicate session is the only sane behaviour.

Benjamin Herrenschmidt says: ==================== ftgmac100: Rework batch 3 - TX path This is version 2 of the third batch of updates to the ftgmac100 driver. This one tackles the TX path of the driver. This provides the bulk of the performance improvements by adding support for fragmented sends along with a bunch of cleanups. Version 2 fixes a patch splitting mistake and uses eth_skb_pad() (which uses skb_put_padto) to pad ethernet frames rather than skb_padto(), thus removing the need to also pad the packet headlen in a couple of places. Subsequent batches will add various features (ethtool functions, vlan offlan, ...) and cleanups. ==================== Signed-off-by:
