Avoid copying to the output buffer in cmd_exec since this is done after the command is completed. Failure to do this may cause cases where the callback handler is called before the copy done by cmd_exec which then overwrites it. Reported-by:

Jon Maloy says: ==================== tipc: remove some unnecessary complexity The TIPC code is unnecessarily complex in some places, often because the conditions or assumptions that were the cause for the complexity are not valid anymore. In these three commits, we eliminate some cases of such redundant complexity. ==================== Signed-off-by: -

When a link is being established, the two endpoints advertise their respective interface MTU in the transmitted RESET and ACTIVATE messages. If there is any difference, the lower of the two MTUs will be selected for use by both endpoints. However, as a remnant of earlier attempts to introduce TIPC level routing. there also exists an MTU discovery mechanism. If an intermediate node has a lower MTU than the two endpoints, they will discover this through a bisectional approach, and finally adopt this MTU for common use. Since there is no TIPC level routing, and probably never will be, this mechanism doesn't make any sense, and only serves to make the link level protocol unecessarily complex. In this commit, we eliminate the MTU discovery algorithm,and fall back to the simple MTU advertising approach. This change is fully backwards compatible. Reviewed-by:

When a bearer is disabled manually, all its links have to be reset and deleted. However, if there is a remaining, parallel link ready to take over a deleted link's traffic, we currently delay the delete of the removed link until the failover procedure is finished. This is because the remaining link needs to access state from the reset link, such as the last received packet number, and any partially reassembled buffer, in order to perform a successful failover. In this commit, we do instead move the state data over to the new link, so that it can fulfill the procedure autonomously, without accessing any data on the old link. This means that we can now proceed and delete all pertaining links immediately when a bearer is disabled. This saves us from some unnecessary complexity in such situations. We also choose to change the confusing definitions CHANGEOVER_PROTOCOL, ORIGINAL_MSG and DUPLICATE_MSG to the more descriptive TUNNEL_PROTOCOL, FAILOVER_MSG and SYNCH_MSG respectively. Reviewed-by:

In commit 8b4ed863 ("tipc: eliminate race condition at dual link establishment") we introduced a parallel link synchronization mechanism that guarentees sequential delivery even for users switching from an old to a newly established link. The new mechanism makes it unnecessary to deliver the tunneled duplicate packets back to the old link, as we are currently doing. It is now sufficient to use the last tunneled packet's inner sequence number as synchronization point between the two parallel links, whereafter it can be dropped. In this commit, we drop the duplicate packets arriving on the new link, after updating the synchronization point at each new arrival. Although it would now have been sufficient for the other endpoint to only tunnel the last packet in its send queue, and not the entire queue, we must still do this to maintain compatibility with older nodes. This commit makes it possible to get rid if some complex interaction between the two parallel links. Reviewed-by:

Or Gerlitz says: ==================== Mellanox mlx4 driver updates The main feature added by this series are Ido's changes to support Granular QoS for VFs, where for the time being only max rate is supported. Muhammad added support for setting rx-fcs and rx-all through ethtool, and Ido did the interface identify work. Last, add Ido as a maintainer for the mlx4 Ethernet driver! Some of next week is the Passover holiday here and I will be mostly OOO. If needed (...) Ido or Amir will send V1 and such. Rebased against net-next commit 033f46b3 "crypto: algif - explicitly mark end of data". ==================== Signed-off-by:

Support granular QoS per VF, by implementing the ndo_set_vf_rate. Enforce a rate limit per VF when called, and enabled only for VFs in VST mode with user priority supported by the device. We don't enforce VFs to be in VST mode at the moment of configuration, but rather save the given rate limit and enforce it when the VF is moved to VST with user priority which is supported (currently 0). VST<->VGT or VST qos value state changes are disallowed when a rate limit is configured. Minimum BW share is not supported yet. Signed-off-by:

Granular QoS per VF feature introduce a new QP field, qos_vport. PF administrator can connect VF QPs to a certain QoS Vport, to inherit its proporties. Connecting QPs to the default QoS Vport (defined as 0) is always allowed, even when there are no allocated VPPs. At this point, only the default vport is connected to QPs. Signed-off-by:

Initialization of granular Qos per VF mechanism. Query the port availible VPPs and allocates those on all supported priorities in an equal share. Allocation is done only in SRIOV mode, when the feature is supported by the device and port type is Ethernet. Allocation currently is done only on the default priority 0. Signed-off-by:

Add the SET_VPORT_QOS device command, which is ntended for virtual granular QoS configuration per VF in SRIOV mode. The SET_VPORT_QOS command sets and queries QoS parameters of a VPort. Each priority allowed for a VPort is assigned with a share of the BW, and a BW limitation. QoS parameters can be modified at any time, but must be initialized before any QP is associated with the VPort. Signed-off-by:

Implements device ALLOCATE_VPP command, to be used for granular QoS configuration of VFs by the PF device. Defines and queries the amount of VPPs assigned to each port, and the amount of VPPs assigned to each priority of each port. Once the total VPPs are split between the priorities of a port, they may be assigned with a share of the BW or a rate limit. Split into two functions (get/set) whoch are supplied with mlx4_alloc_vpp_context and physical port number. Signed-off-by:

Enable RSS support for fragmented IP packets, when device supports it. Until now, fragmented IP packets were directed only to the default_qpn. Since IP fragments (datagram) have no upper protocols (L3 IP packets), hash is performed on 3-tuple - dst MAC, source IP and dest IP. The HW makes sure that this holds for the 1st fragment too, so all fragments go to the same QP. Signed-off-by:

In 'net' we added a READ_ONCE() to the socket cached RX route read, whilst in 'net-next' Eric Dumazet touched the surrounding code dealing with how mini sockets are handled. With USB, it's a case of the same bug fix first going into net-next and then I cherry picked it back into net. Signed-off-by: -
