2018-03-28iwlwifi: mvm: check if mac80211_queue is valid in iwl_mvm_disable_txqLuca Coelho
Sometimes iwl_mvm_disable_txq() may be called with mac80211_queue == IEEE80211_INVAL_HW_QUEUE, and this would cause us to use BIT(0xFF) which is way too large for the u16 we used to store it in hw_queue_to_mac820211. If this happens the following UBSAN warning will be generated: [ 167.185167] UBSAN: Undefined behaviour in drivers/net/wireless/intel/iwlwifi/mvm/utils.c:838:5 [ 167.185171] shift exponent 255 is too large for 64-bit type 'long unsigned int' Fix that by checking that it is not IEEE80211_INVAL_HW_QUEUE and, while at it, add a warning if the queue number is larger than IEEE80211_MAX_QUEUES.

2018-03-28drm/i915/gvt: Make MI_USER_INTERRUPT nop in cmd parserZhipeng Gong
GVT-g dispatches request to host i915 and depends on i915 notify ring interrupt mechanism to check completion of request. For now MI_USER_INTERRUPT in guest requests is passed through in GVT-g cmd parser and i915 does not use it, which causes unnecessary interrupt handling in i915. On the other hand, if several requests from guest are combined into one request in and contain MI_USER_INTERRUPT in the middle of combined request. GVT-g still has to wait on the whole request to complete to inject user interrupts to guest. This patch makes all the MI_USER_INTERRUPT nop to save some interrupt handling. Here is test result to run glmark2 on guest for 10 seconds: host master interrupts number is reduced from 16021 to 11162 host user interrupts number is reduced from 7936 to 3536 v2: - revise commit message.

2018-03-27rpmsg: smd: Use announce_create to process any receive workBjorn Andersson
It is possible that incoming data arrives before the client driver has reached a point in the probe method where adequate context for handling the incoming message has been established. In the event that the client's callback function returns an error the message will be left on the FIFO and by invoking the receive handler after the device has been probed the message will be picked off the FIFO and the callback invoked again.

2018-03-27net/mlx5e: Recover Send Queue (SQ) from error stateEran Ben Elisha
An error TX completion (CQE) which arrived on a specific SQ indicates that this SQ got moved by the hardware to error state, which means all pending and incoming TX requests are dropped or will be dropped and no further "Good" CQEs will be generated for that SQ. Before this patch TX completions (CQEs) were not monitored and were handled as a regular CQE. This caused the SQ to stay in an error state, making it useless for xmiting new packets. Mitigation plan: In case of an error completion, schedule a recovery work which would do the following: - Mark the TXQ as DRV_XOFF to disable new packets to arrive from the stack - NAPI to flush all pending SQ WQEs (via flush_in_error_en bit) to release SW and HW resources(SKB, DMA, etc) and have the SQ and CQ consumer/producer indices synced. - Modify the SQ state ERR -> RST -> RDY (restart the SQ). - Reactivate the SQ and reset SQ cc and pc If we identify two consecutive requests for SQ recover in less than 500 msecs, drop the recover request to avoid CPU overload, as this scenario most likely happened due to a severe repeated bug. In addition, add SQ recover SW counter to monitor successful recoveries. Signed-off-by: Eran Ben Elisha <eranbe@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
