In its attempt to run only the minimal amount of tear down steps, qeth_l2_stop_card() fails to reset the "is dev_addr registered?" flag in some rare scenarios. But a future change to the tear down sequence would cause us to _always_ hit this issue, so patch it up before that code lands. Fix it by unconditionally clearing the flag bit. This also allows us to remove the additional cleanup step in qeth_dev_layer2_store(). Signed-off-by:

When setting a L2 qeth device online, enable the HW trap as soon as the control plane is available. This allows us to catch any error that occurs during the very first commands. In the same spirit, the offline code should disable the HW trap as the very first step of its processing. Signed-off-by:

The offline code uses a specific RECOVER state to indicate that the interface should be brought up when a qeth device is set online again. Rather than having a specific card-state for this, just put it in an internal flag bit and set the state to DOWN. When working with the card's state transitions, this reduces the complexity quite a bit. Signed-off-by:

Without hardware pnetid support there must currently be a pnet table configured to determine the IB device port to be used for SMC RDMA traffic. This patch enables a setup without pnet table, if the used handshake interface belongs already to a RoCE port. Signed-off-by:

As per RFC 8033, it is sufficient for the drop probability decay factor to have a value of (1 - 1/64) instead of 98%. This avoids the need to do slow division. Suggested-by:

GRO is done by cxgb4/cxgb4vf. Hence set NETIF_F_GRO flag for both cxgb4/cxgb4vf. Cleaned up VLAN netdev features in cxgb4vf. Also fixed NETIF_F_HIGHDMA being set unconditionally for vlan netdev features. Signed-off-by:

The csum calculation is different for IPv4/6. For VLAN packets, tc_skb_protocol returns the VLAN protocol rather than the packet's one (e.g. IPv4/6), so csum is not calculated. Furthermore, VLAN may not be stripped so csum is not calculated in this case too. Calculate the csum for those cases. Fixes: d8b9605d ("net: sched: fix skb->protocol use in case of accelerated vlan path") Signed-off-by:

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(struct boo) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

Maxime Chevallier says: ==================== net: phy: marvell10g: Clean .get_features by using C45 helpers Recent work on C45 helpers by Heiner made the genphy_c45_pma_read_abilities function generic enough to use as a default .get_featutes implementation. This series removes the remaining redundant code in mv3310_get_features(), and makes the 2110 PHY use genphy_c45_pma_read_abilities() directly, since it doesn't have the issue with the wrong abilities being reported. ==================== Signed-off-by: -

Contrary to the 3310, the 2110 PHY correctly reports it's 2.5G/5G abilities. We can therefore use the genphy_c45_pma_read_abilities helper to build the list of features. Signed-off-by:

The genphy_c45_pma_read_abilities helper now sets the Autoneg ability in phydev->supported according to what the AN MMD reports. We therefore don't need to manually do that in mv3310_get_features(). Signed-off-by:

Tunnel key action params->tcft_enc_metadata is only set when action is TCA_TUNNEL_KEY_ACT_SET. However, metadata pointer is incorrectly dereferenced during tunnel key init and release without verifying that action is if correct type, which causes NULL pointer dereference. Metadata tunnel dst_cache is also leaked on action overwrite. Fix metadata handling: - Verify that metadata pointer is not NULL before dereferencing it in tunnel_key_init error handling code. - Move dst_cache destroy code into tunnel_key_release_params() function that is called in both action overwrite and release cases (fixes resource leak) and verifies that actions has correct type before dereferencing metadata pointer (fixes NULL pointer dereference).

Current fib_multipath_hash_policy can make hash based on the L3 or L4. But it only work on the outer IP. So a specific tunnel always has the same hash value. But a specific tunnel may contain so many inner connections. This patch provide a generic multipath_hash in floi_common. It can make a user-define hash which can mix with L3 or L4 hash.

Florian Fainelli says: ==================== net: Remove switchdev_ops This patch series completes the removal of the switchdev_ops by converting switchdev_port_attr_set() to use either the blocking (process) or non-blocking (atomic) notifier since we typically need to deal with both depending on where in the bridge code we get called from. This was tested with the forwarding selftests and DSA hardware. Ido, hopefully this captures your comments done on v1, if not, can you illustrate with some pseudo-code what you had in mind if that's okay? Changes in v3: - added Reviewed-by tags from Ido where relevant - added missing notifier_to_errno() in net/bridge/br_switchdev.c when calling the atomic notifier for PRE_BRIDGE_FLAGS - kept mlxsw_sp_switchdev_init() in mlxsw/ Changes in v2: - do not check for SWITCHDEV_F_DEFER when calling the blocking notifier and instead directly call the atomic notifier from the single location where this is required ==================== Signed-off-by: -

Drop switchdev_ops.switchdev_port_attr_set. Drop the uses of this field from all clients, which were migrated to use switchdev notification in the previous patches. Add a new function switchdev_port_attr_notify() that sends the switchdev notifications SWITCHDEV_PORT_ATTR_SET and calls the blocking (process) notifier chain. We have one odd case within net/bridge/br_switchdev.c with the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier that requires executing from atomic context, we deal with that one specifically. Drop __switchdev_port_attr_set() and update switchdev_port_attr_set() likewise. Signed-off-by:

Following patches will change the way we communicate setting a port's attribute and use notifiers to perform those tasks. Ocelot does not currently have an atomic notifier registered for switchdev events, so we need to register one in order to deal with atomic context SWITCHDEV_PORT_ATTR_SET events. Signed-off-by:

This reverts commit 31a99848 ("net: sched: fw: don't set arg->stop in fw_walk() when empty") Cls API function tcf_proto_is_empty() was changed in commit 6676d5e4 ("net: sched: set dedicated tcf_walker flag when tp is empty") to no longer depend on arg->stop to determine that classifier instance is empty. Instead, it adds dedicated arg->nonempty field, which makes the fix in fw classifier no longer necessary. Signed-off-by:
