The reference to err_no was left around after a previous code refactor. We never use the value, and it doesn't seem to be used in side a hidden macro reference. Discovered via cppcheck.

This patch adds the __attribute__((packed)) indicator to some structures which are overlayed onto a TLV message. These structures must be packed as small as possible in order to correctly align when copied into the mailbox buffer. Without doing so, the receiving mailbox code incorrectly parses the values and we get invalid message responses from the switch manager software.

During initialization, the VF counts its rings by walking the TQDLOC registers. This works only if the TQMAP/RQMAP registers are set to map all of the out-of-bound rings back to the first one. This allows the VF to cleanly detect when it has run out of queues. Update the PF code so that it resets the empty TQMAP/RQMAP registers post-VFLR to prevent innocent VF drivers from triggering malicious driver events.

Currently, we don't notify the switch at all when the PF administratively sets a new VLAN or MAC address. This causes the old addresses to remain valid on the switch table. Since the PF is overriding any configuration done directly by the VF, we choose to simply re-create the LPORT for the VF. This does mean that all rules for the VF will be dropped when we set something directly via the PF, but it prevents some weird issues where the MAC/VLAN table retains some stale configuration.

This patch cleans up the use of dma_get_required_mask and uses the simpler dma_set_mask_and_coherent function instead of doing these as separate steps. I removed the dma_get_required_mask call because based on some minimal testing it appears that either (a) we're not doing the right thing with the call or (b) we don't need it anyways. If the value returned is <48bits, we'll end up trying with 48 bits anyways. If it's over 48bits, fm10k can't support that anyways, and we should try 48bits. If 48bits fails, we'll fallback to 32bits. This cleans up some very funky code. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

This prevents a memory leak in fm10k_set_ringparams. The leak occurs because we go down, change ring parameters, and then come up. However, fm10k_down on its own is not clearing the Rx rings. Since fm10k_up assumes the rings are clean we basically drop the buffers and leak a bunch of memory. Eventually we hit dirty page faults and reboot the system. This issue does not occur elsewhere because other flows that involve fm10k_down go through fm10k_close which immediately called fm10k_free_all_rx_resources which properly cleans the rings.

This patch resolves a bug in the ts_tx_enqueue code responsible for a NULL pointer dereference and invalid access of the skb list. We incorrectly freed the actual skb we found instead of our copy. Thus the skb queue is essentially invalidated. Resolve this by freeing our clone in the cases where we did not add it to the queue. This also avoids the skb memory leak caused by failure to free the clone.

skb_complete_tx_timestamp is intended for use by PHY drivers which implement a different method of returning timestamps. This method is intended to be used after a PHY driver accepts a cloned packet via its phy_driver.txtstamp function. It is not correct to use in the standard ethernet driver such as fm10k.

This change fixes an issue with adding an invalid multicast address using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2 tool and the kernel do not validate or filter the multicast addresses when adding them to the multicast list. Thus, when synchronizing this list with an invalid entry, the action will be aborted with an error since the fm10k driver currently validates the list. Consequently, multicast entries beyond the invalid one will not be processed and communicated with the switch via the mailbox. This change makes it so that invalid addresses will simply be skipped and allows synchronizing the full list to proceed.

Craig Gallek says: ==================== Socket destruction events via netlink sock_diag This series extends the netlink sock_diag interface to broadcast socket information as they are being destroyed. The current interface is poll based and can not be used to retreive information about sockets that are destroyed between poll intervals. Only inet sockets are broadcast in this implementation, but other families could easily be added as needed in the future.

This get_info handler will simply dispatch to the appropriate existing inet protocol handler. This patch also includes a new netlink attribute (INET_DIAG_PROTOCOL). This attribute is currently only used for multicast messages. Without this attribute, there is no way of knowing the IP protocol used by the socket information being broadcast. This attribute is not necessary in the 'dump' variant of this protocol (though it could easily be added) because dump requests are issued for specific family/protocol pairs.

This change adds a specific size attribute to the inet_diag_handler struct which defines these interfaces.

In the presence of a listener, rather than completely cleanup the socket, a unit of work will be added to a private work queue which will first broadcast information about the socket and then finish the cleanup operation.

This is an infrastructure step to attach all the QPs opened from the IB driver to a counter in order to collect VF stats from the PF using those counters. If the port's type is Ethernet, the counter policy demands two counters per port (one for RoCE and one for Ethernet). The port default counter (allocated in mlx4_core) is used for the Ethernet netdev QPs and we allocate another counter for RoCE. If the port's traffic is Infiniband, the counter policy demands one counter per port, so it can use the port's default counter. Also, Add 'allocated' flag for each counter in order to clean it at unload.

We need to delete from offload the device externally learnded fdbs when any one of these events happen: 1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL directly). 2) STP state change flushes fdbs on port. 3) User uses sysfs interface to flush fdbs from bridge or bridge port: echo 1 >/sys/class/net/BR_DEV/bridge/flush echo 1 >/sys/class/net/BR_PORT/brport/flush 4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry.
