We recently discovered a bug in the firmware in which a field's length in one of the registers was incorrectly set. This caused the firmware to access garbage data that wasn't initialized by the driver and therefore emit error messages. While the bug is already fixed and the driver usually zeros the buffers passed to the firmware, there are a handful of cases where this isn't done. Zero the buffer in these cases and prevent similar bugs from recurring, as they tend to be hard to debug. Fixes: 52581961 ("mlxsw: core: Implement fan control using hwmon") Signed-off-by:

The maximum unicast datagram size /without/ link fragmentation is 4096 - 4 = 4092 (max IEEE 1394 async payload size at >= S800 bus speed, minus unfragmented encapssulation header). Max broadcast datagram size without fragmentation is 8 bytes less than that (due to GASP header). The maximum datagram size /with/ link fragmentation is 0xfff = 4095 for unicast and broadcast. This is because the RFC 2734 fragment encapsulation header field for datagram size is only 12 bits wide. Fixes: 5d48f00d('firewire: net: fix maximum possible MTU') Signed-off-by:

Driver allocates a shadow array for transmitted SKBs with X entries; That means valid indices are {0,...,X - 1}. [X == 8191] Problem is the driver also uses X as a mask for a producer/consumer in order to choose the right entry in the array which allows access to entry X which is out of bounds. To fix this, simply allocate X + 1 entries in the shadow array. Signed-off-by:Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by:

When MTU is changed from 9000 to 1500 while there is burst of inbound 9000 bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes buffers. This causes memory corruption and sometimes crash. This is because of a race condition in adaptor between "RQ disable" clearing descriptor mini-cache and mini-cache valid bit being set by completion of descriptor fetch. This can result in stale RQ desc being cached and used when packets arrive. In this case, the stale descriptor have old MTU value. Solution is to write RQ->disable twice. The first write will stop any further desc fetches, allowing the second disable to clear the mini-cache valid bit without danger of a race. Also, the check for rq->running becoming 0 after writing rq->enable to 0 is not done properly. When incoming packets are flooding the interface, rq->running will pulse high for each dropped packet. Since the driver was waiting for 10us between each poll, it is possible to see rq->running = 1 1000 times in a row, even though it is not actually stuck running. This results in false failure of vnic_rq_disable(). Fix is to try more than 1000 time without delay between polls to ensure we do not miss when running goes low. In old adaptors rq->enable needs to be re-written to 0 when posted_index is reset in vnic_rq_clean() in order to keep rq->prefetch_index in sync. Signed-off-by:

In commit 2d18ac4b ("tipc: extend broadcast link initialization criteria") we tried to fix a problem with the initial synchronization of broadcast link acknowledge values. Unfortunately that solution is not sufficient to solve the issue. We have seen it happen that LINK_PROTOCOL/STATE packets with a valid non-zero unicast acknowledge number may bypass BCAST_PROTOCOL initialization, NAME_DISTRIBUTOR and other STATE packets with invalid broadcast acknowledge numbers, leading to premature opening of the broadcast link. When the bypassed packets finally arrive, they are inadvertently accepted, and the already correctly initialized acknowledge number in the broadcast receive link is overwritten by the invalid (zero) value of the said packets. After this the broadcast link goes stale. We now fix this by marking the packets where we know the acknowledge value is or may be invalid, and then ignoring the acks from those. To this purpose, we claim an unused bit in the header to indicate that the value is invalid. We set the bit to 1 in the initial BCAST_PROTOCOL synchronization packet and all initial ("bulk") NAME_DISTRIBUTOR packets, plus those LINK_PROTOCOL packets sent out before the broadcast links are fully synchronized. This minor protocol update is fully backwards compatible. Reported-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-10-27 This series contains fixes to ixgbe and i40e. Emil fixes a NULL pointer dereference when a macvlan interface is brought up while the PF is still down. David root caused the original panic that was fixed by commit id (a036244c "i40e: Fix kernel panic on enable/disable LLDP") and the fix was not quite correct, so removed the get_default_tc() and replaced it with a #define since there is only one TC supported as a default. Guilherme Piccoli fixes an issue where if we modprobe the driver module without enough MSI-X interrupts, then unload the module and reload it again, the kernel would crash. So if we fail to allocate enough MSI-X interrupts, we should disable them since they were previously enabled. Huaibin Wang found that the order of the arguments for ndo_dflt_bridge_getlink() were in the correct order, so fix the order. ==================== Signed-off-by:

Jack Morgenstein authored
mlx4_en_DUMP_ETH_STATS took the *counter mutex* and then called the FW command, with WRAPPED attribute. As a result, the fw command is wrapped on the Hypervisor when it calls mlx4_en_DUMP_ETH_STATS. The FW command wrapper flow on the hypervisor takes the *slave_cmd_mutex* during processing. At the same time, a VF could be in the process of coming up, and could call mlx4_QUERY_FUNC_CAP. On the hypervisor, the command flow takes the *slave_cmd_mutex*, then executes mlx4_QUERY_FUNC_CAP_wrapper. mlx4_QUERY_FUNC_CAP wrapper calls mlx4_get_default_counter_index(), which takes the *counter mutex*. DEADLOCK. The fix is that the DUMP_ETH_STATS fw command should be called with the NATIVE attribute, so that on the hypervisor, this command does not enter the wrapper flow. Since the Hypervisor no longer goes through the wrapper code, we also simply return 0 in mlx4_DUMP_ETH_STATS_wrapper (i.e.the function succeeds, but the returned data will be all zeroes). No need to test if it is the Hypervisor going through the wrapper. Fixes: f9baff50 ("mlx4_core: Add "native" argument to mlx4_cmd ...") Signed-off-by:

In the Hypervisor, there are several FW commands which are invoked before the comm channel is initialized (in mlx4_multi_func_init). These include MOD_STAT_CONFIG, QUERY_DEV_CAP, INIT_HCA, and others. If any of these commands fails, say with a timeout, the Hypervisor driver enters the internal error reset flow. In this flow, the driver attempts to notify all slaves via the comm channel that an internal error has occurred. Since the comm channel has not yet been initialized (i.e., mapped via ioremap), this will cause dereferencing a NULL pointer. To fix this, do not access the comm channel in the internal error flow if it has not yet been initialized.

Currently there is a race between incoming traffic and initialization flow. HW is able to receive the packets after INIT_PORT is done and unicast steering is configured. Before we set priv->port_up NAPI is not scheduled and receive queues become full. Therefore we never get new interrupts about the completions. This issue could happen if running heavy traffic during bringing port up. The resolution is to schedule NAPI once port_up is set. If receive queues were full this will process all cqes and release them. Fixes: c27a02cd ("mlx4_en: Add driver for Mellanox ConnectX 10GbE NIC") Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-10-28 This series contains updates to i40e and i40evf only. Carolyn provides a couple of fixes, first resolving a problem in the client interface that was causing random stack traces in the RDMA driver which was due to a timing related NULL pointer dereference. Fixed a problem where it could take a very long time to print the link down notification, by changing how often we update link info from firmware. Alex provides a number of changes, first is a re-write of the bust wait loop in the Flow Director transmit function to reduce code size. Cleans up unused code in favor of the same functionality which can be inlined. Dropped the functionality for SCTP since we cannot currently support it. Cleans up redundant code in the receive clean-up path. Finally cleaned up the convoluted configuration for how the driver handled the debug flags contained in msg_level. Filip fixes an incorrect bit mask which was being used for testing the "get link status". Cleaned up a workaround that is no longer needed for production NICs and was causing frames to pass while disregarding the VLAN tagging. Mitch brings another fix for the client interface supporting the VF RDMA driver to allow clients to recover from reset by re-opening existing clients. Alan fixes a bug in which a "perfect storm" can occur and cause interrupts to fail to be correctly affinitized. Lihong fixes a confusing dmesg reported when users were using ethtool -L option. ==================== Signed-off-by: -
