The cited commit introduce new CONFIG_MLX5_CLS_ACT kconfig variable to control compilation of TC hardware offloads implementation. When this configuration is disabled the driver is still wrongly reports in ethtool that hw-tc-offload is supported. Fixed by reporting hw-tc-offload is supported only when CONFIG_MLX5_CLS_ACT is enabled. Fixes: d956873f ("net/mlx5e: Introduce kconfig var for TC support") Signed-off-by:

Pages for the host PF and ECPF were stored in the same tree, so the ECPF pages were being freed along with the host PF's when the host driver unloaded. Combine the function ID and ECPF flag to use as an index into the x-array containing the trees to get a different tree for the host PF and ECPF.

When IPSEC offload isn't active, the number of stats is not zero, but the strings are not filled, leading to exposing stats with empty names.

rate_bytes_ps is a 64-bit field. It passed as 32-bit field to apply_police_params(). Due to this when police rate is higher than 4Gbps, 32-bit calculation ignores the carry.

This code ends up calling wiphy_apply_custom_regulatory(), for which we document that it should be called before wiphy_register(). This driver doesn't do that, but calls it from ndo_open() with the RTNL held, which caused deadlocks. Since the driver just registers static regdomain data and then the notifier applies the channel changes if any, there's no reason for it to call this in ndo_open(), move it earlier to fix the deadlock.

syzbot reported a crash that happened when changing the interface type around a lot, and while it might have been easy to fix just the symptom there, a little deeper investigation found that really the reason is that we allowed packets to be transmitted while in the middle of changing the interface type. Disallow TX by stopping the queues while changing the type.

Since cfg80211 doesn't implement commit, we never really cared about that code there (and it's configured out w/o CONFIG_WIRELESS_EXT). After all, since it has no commit, it shouldn't return -EIWCOMMIT to indicate commit is needed. However, EIWCOMMIT is actually an alias for EINPROGRESS, which _can_ happen if e.g. we try to change the frequency but we're already in the process of connecting to some network, and drivers could return that value (or even cfg80211 itself might). This then causes us to crash because dev->wireless_handlers is NULL but we try to check dev->wireless_handlers->standard[0]. Fix this by also checking dev->wireless_handlers. Also simplify the code a little bit.

In D3 resume flow, avoid the following race where sending packets before updating the sequence number (sequence number received from the wowlan status command response): Thread 1: __iwl_mvm_resume clears IWL_MVM_STATUS_IN_D3 and is cut by thread 2 before reaching iwl_mvm_query_wakeup_reasons. Thread 2: iwl_mvm_mac_itxq_xmit calls iwl_mvm_tx_skb since IWL_MVM_STATUS_IN_D3 is not set using a wrong sequence number. Thread 1: __iwl_mvm_resume continues and calls iwl_mvm_query_wakeup_reasons updating the sequence number received from the firmware. The next packet that will be sent now will cause sysassert 0x1096.

Having sta_id not set for aux_sta and snif_sta can potentially lead to a hard to debug issue in case remove station is called without an add. In this case sta_id 0, an unrelated regular station, will be removed. In fact, we do have a FW assert that occures rarely and from the debug data analysis it looks like sta_id 0 is removed by mistake, though it's hard to pinpoint the exact flow.

If we spin for a long time in memory reads that (for some reason in hardware) take a long time, then we'll eventually get messages such as watchdog: BUG: soft lockup - CPU#2 stuck for 24s! [kworker/2:2:272] This is because the reading really does take a very long time, and we don't schedule, so we're hogging the CPU with this task, at least if CONFIG_PREEMPT is not set, e.g. with CONFIG_PREEMPT_VOLUNTARY=y. Previously I misinterpreted the situation and thought that this was only going to happen if we had interrupts disabled, and then fixed this (which is good anyway, however), but that didn't always help; looking at it again now I realized that the spin unlock will only reschedule if CONFIG_PREEMPT is used. In order to avoid this issue, change the code to cond_resched() if we've been spinning for too long here. Signed-off-by:

There's no reason to use ktime_get() since we don't need any better precision than jiffies, and since we no longer disable interrupts around this code (when grabbing NIC access), jiffies will work fine. Use jiffies instead of ktime_get(). This cleanup is preparation for the following patch "iwlwifi: pcie: reschedule in long-running memory reads". The code gets simpler with the weird clock use etc. removed before we add cond_resched(). Signed-off-by:

I noticed that the flow that triggers an NMI on the firmware for old devices (tested on 7265) doesn't work. Apparently, the firmware / device is still in low power when we write the register that triggers the NMI. We call the "grab_nic_access" function to make sure the device is awake but that wasn't enough. I played with this and noticed that if we wait 1 ms after the device reports it is awake before we write to the NMI register, the device always sees our write and the firmware gets properly asserted. Triggering an NMI to the firmware can be done with the debugfs hook: echo 1 > /sys/kernel/debug/iwlwifi/0000\:00\:03.0/iwlmvm/fw_nmi What happened before is that the firmware would just stall without running its NMI routine. Because of that the driver wouldn't get the "firmware crashed" interrupt. After a while the driver would notice that the firmware is not responding to some command and it would read the error data from the firmware, but this data is populated in the NMI service routine in the firmware which was not called. So in the logs it looked like: iwlwifi 0000:00:03.0: Error sending REPLY_ERROR: time out after 2000ms. iwlwifi 0000:00:03.0: Current CMD queue read_ptr 33 write_ptr 34 iwlwifi 0000:00:03.0: Loaded firmware version: 29.09bd31e1.0 7265D-29.ucode iwlwifi 0000:00:03.0: 0x00000000 | ADVANCED_SYSASSERT iwlwifi 0000:00:03.0: 0x00000000 | trm_hw_status0 iwlwifi 0000:00:03.0: 0x00000000 | trm_hw_status1 iwlwifi 0000:00:03.0: 0x00000000 | branchlink2 iwlwifi 0000:00:03.0: 0x00000000 | interruptlink1 iwlwifi 0000:00:03.0: 0x00000000 | interruptlink2 iwlwifi 0000:00:03.0: 0x00000000 | data1 iwlwifi 0000:00:03.0: 0x00000000 | data2 iwlwifi 0000:00:03.0: 0x00000000 | data3 iwlwifi 0000:00:03.0: 0x00000000 | beacon time iwlwifi 0000:00:03.0: 0x00000000 | tsf low ...

In the new CSA flow, we remain associated during CSA, but still do a unbind-bind to the vif. However, sending the power command right after when vif is unbound but still associated causes FW to assert (0x3400) since it cannot tell the LMAC id. Just skip this command, we will send it again in a bit, when assigning the new context. Signed-off-by:

Upon receiving a cumulative ACK that changes the congestion state from Disorder to Open, the TLP timer is not set. If the sender is app-limited, it can only wait for the RTO timer to expire and retransmit. The reason for this is that the TLP timer is set before the congestion state changes in tcp_ack(), so we delay the time point of calling tcp_set_xmit_timer() until after tcp_fastretrans_alert() returns and remove the FLAG_SET_XMIT_TIMER from ack_flag when the RACK reorder timer is set. This commit has two additional benefits: 1) Make sure to reset RTO according to RFC6298 when receiving ACK, to avoid spurious RTO caused by RTO timer early expires. 2) Reduce the xmit timer reschedule once per ACK when the RACK reorder timer is set.

The TCP_USER_TIMEOUT is checked by the 0-window probe timer. As the timer has backoff with a max interval of about two minutes, the actual timeout for TCP_USER_TIMEOUT can be off by up to two minutes. In this patch the TCP_USER_TIMEOUT is made more accurate by taking it into account when computing the timer value for the 0-window probes. This patch is similar to and builds on top of the one that made TCP_USER_TIMEOUT accurate for RTOs in commit b701a99e ("tcp: Add tcp_clamp_rto_to_user_timeout() helper to improve accuracy"). Fixes: 9721e709 ("tcp: simplify window probe aborting on USER_TIMEOUT") Signed-off-by:
