2025-03-22wifi: iwlwifi: mvm: fix PNVM timeout for non-MSI-X platformsEmmanuel Grumbach
[ Upstream commit b8c8a03e9b7bfc06f366b75daf3d0812400e7123 ] When MSI-X is not enabled, we mask all the interrupts in the interrupt handler and re-enable them when the interrupt thread runs. If STATUS_INT_ENABLED is not set, we won't re-enable in the thread. In order to get the ALIVE interrupt, we allow the ALIVE interrupt itself, and RX as well in order to receive the ALIVE notification (which is received as an RX from the firmware. The problem is that STATUS_INT_ENABLED is clear until the op_mode calls trans_fw_alive which means that until trans_fw_alive is called, any notification from the firmware will not be received. This became a problem when we inserted the pnvm_load exactly between the ALIVE and trans_fw_alive. Fix that by calling trans_fw_alive before loading the PNVM. This will allow to get the notification from the firmware about PNVM load being complete and continue the flow normally. This didn't happen on MSI-X because we don't disable the interrupts in the ISR when MSI-X is available. The error in the log looks like this: iwlwifi 0000:00:03.0: Timeout waiting for PNVM load! iwlwifi 0000:00:03.0: Failed to start RT ucode: -110 iwlwifi 0000:00:03.0: WRT: Collecting data: ini trigger 13 fired (delay=0ms).

2025-03-13wifi: iwlwifi: pcie: Fix TSO preparationIlan Peer
commit bbb18f7e23a3f5f56d5c8b4ee0f78f00edb3b1b2 upstream. The allocation of the scatter gather data structure should be done based on the number of memory chunks that need to be mapped, and it is not dependent on the overall payload length. Fix it. In addition, as the skb_to_sgvec() function returns an 'int' do not assign it to an 'unsigned int' as otherwise the error check would be useless.

Since this reason is refcounted, we won't wake up the queues since we wake them up only once and the ref count will never reach 0. This led to blocked queues that prevented any activity (even disconnection wouldn't reset the queue state and the only way to recover would be to reload the kernel module.

2024-10-25wifi: iwlwifi: mvm: fix 6 GHz scan constructionJohannes Berg
If more than 255 colocated APs exist for the set of all APs found during 2.4/5 GHz scanning, then the 6 GHz scan construction will loop forever since the loop variable has type u8, which can never reach the number found when that's bigger than 255, and is stored in a u32 variable. Also move it into the loops to have a smaller scope. Using a u32 there is fine, we limit the number of APs in the scan list and each has a limit on the number of RNR entries due to the frame size. With a limit of 1000 scan results, a frame size upper bound of 4096 (really it's more like ~2300) and a TBTT entry size of at least 11, we get an upper bound for the number of ~372k, well in the bounds of a u32.

When starting the suspend flow, HOST_D3_START triggers an _async_ firmware dump collection for debugging purposes. The async worker may race with suspend flow and fail to get NIC access, resulting in the following warning: "Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff)" Fix this by switching to the sync version to ensure the dump completes before proceeding with the suspend flow, avoiding potential race issues.

Fix this by calling iwl_mvm_send_ap_tx_power_constraint_cmd before iwl_mvm_link_changed.

2024-09-03wifi: iwlwifi: mvm: properly set the rates in link cmdMiri Korenblit
When a channel ctx is assigned to a link, we set the LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now valid. But then we always take the rates of 2.4 GHz regardless of actual used band. This is because we are getting the band from bss_conf->chanctx_conf, but this is assigned only after drv_assign_vif_chanctx returns, so we take the bands of 2.4 GHz. Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead, as this has already assigned in this point.

The firmware will do that on its own if the CSA indication (beacon / action frame) was received on that same link, but with MLO, things got more complex and the firmware can't track cross link CSA. Tell the firmware if we de-activate a link because of CSA with mode=1 to prevent it from transmitting, even if it is only an NDP PM=1 frame that is part of the de-activation flow.

2024-08-27wifi: iwlwifi: mvm: drop wrong STA selection in TXJohannes Berg
This shouldn't happen at all, since in station mode all MMPDUs go through the TXQ for the STA, and not this function. There may or may not be a race in mac80211 through which this might happen for some frames while a station is being added, but in that case we can also just drop the frame and pretend the STA didn't exist yet. Also, the code is simply wrong since it uses deflink, and it's not easy to fix it since the mvmvif->ap_sta pointer cannot be used without the mutex, and perhaps the right link might not even be known. Just drop the frame at that point instead of trying to fix it up.
