2024-08-14wifi: rtw89: pci: fix RX tag race condition resulting in wrong RX lengthPing-Ke Shih1-5/+8
[ Upstream commit 94298477f81a1701fc4e1b5a0ce9672acab5dcb2 ] Read 32 bits RX info to a local variable to fix race condition between reading RX length and RX tag. Another solution is to get RX tag at first statement, but adopted solution can save some memory read, and also save 15 bytes binary code. RX tag, a sequence number, is used to ensure that RX data has been DMA to memory completely, so driver must check sequence number is expected before reading other data. This potential problem happens only after enabling 36-bit DMA.

2024-08-14wifi: ath12k: fix race due to setting ATH12K_FLAG_EXT_IRQ_ENABLED too earlyBaochen Qiang1-2/+2
[ Upstream commit 0a993772e0f0934d730c0d451622c80e03a40ab1 ] Commit 5082b3e3027e ("wifi: ath11k: fix race due to setting ATH11K_FLAG_EXT_IRQ_ENABLED too early") fixes a race in ath11k driver. Since ath12k shares the same logic as ath11k, currently the race also exists in ath12k: in ath12k_pci_ext_irq_enable(), ATH12K_FLAG_EXT_IRQ_ENABLED is set before NAPI is enabled. In cases where only one MSI vector is allocated, this results in a race condition: after ATH12K_FLAG_EXT_IRQ_ENABLED is set but before NAPI enabled, CE interrupt breaks in. Since IRQ is shared by CE and data path, ath12k_pci_ext_interrupt_handler() is also called where we call disable_irq_nosync() to disable IRQ. Then napi_schedule() is called but it does nothing because NAPI is not enabled at that time, meaning that ath12k_pci_ext_grp_napi_poll() will never run, so we have no chance to call enable_irq() to enable IRQ back. Since IRQ is shared, all interrupts are disabled and we would finally get no response from target. So port ath11k fix here, this is done by setting ATH12K_FLAG_EXT_IRQ_ENABLED after all NAPI and IRQ work are done. With the fix, we are sure that by the time ATH12K_FLAG_EXT_IRQ_ENABLED is set, NAPI is enabled. Note that the fix above also introduce some side effects: if ath12k_pci_ext_interrupt_handler() breaks in after NAPI enabled but before ATH12K_FLAG_EXT_IRQ_ENABLED set, nothing will be done by the handler this time, the work will be postponed till the next time the IRQ fires. This is found during code review.

commit a47f3320bb4ba6714abe8dddb36399367b491358 upstream. The ext interrupts are enabled when the firmware has been started, but this may never happen, for example, if the board configuration file is missing. When the system is later suspended, the driver unconditionally tries to disable interrupts, which results in an irq disable imbalance and causes the driver to spin indefinitely in napi_synchronize(). Make sure that the interrupts have been enabled before attempting to disable them.

[ Upstream commit 253ec89c9013b0e61f5c54344df7c065d54934d1 ] The Current method for advertising the maximum MBSSID interface count assumes single radio per wiphy (multi wiphy model). However, this assumption is incorrect for multi radio per wiphy (single wiphy model). Therefore, populate the parameter for each radio present in the MAC abstraction layer (ah). This approach ensure scalability for both single wiphy and multi wiphy models.

2024-08-03wifi: rtw88: usb: Further limit the TX aggregationBitterblue Smith9-1/+20
commit d7dd13ea54af8496aca2762a758d817d6813e81c upstream. Currently the number of frames sent to the chip in a single USB Request Block is limited only by the size of the TX buffer, which is 20 KiB. Testing reveals that as many as 13 frames get aggregated. This is more than what any of the chips would like to receive. RTL8822CU, RTL8822BU, and RTL8821CU want at most 3 frames, and RTL8723DU wants only 1 frame per URB. RTL8723DU in particular reliably malfunctions during a speed test if it receives more than 1 frame per URB. All traffic seems to stop. Pinging the AP no longer works. Fix this problem by limiting the number of frames sent to the chip in a single URB according to what each chip likes. Also configure RTL8822CU, RTL8822BU, and RTL8821CU to expect 3 frames per URB. RTL8703B may or may not be found in USB devices. Declare that it wants only 1 frame per URB, just in case. Tested with RTL8723DU and RTL8811CU.

2024-08-03wifi: rtw88: usb: Fix disconnection after beacon lossBitterblue Smith1-0/+2
commit 28818b4d871bc93cc4f5c7c7d7c526a6a096c09c upstream. When there is beacon loss, for example due to unrelated Bluetooth devices transmitting music nearby, the wifi connection dies soon after the first beacon loss message: Apr 28 20:47:14 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:15 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:24 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:25 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:34 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:35 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 When the beacon loss happens, mac80211 makes rtw88 transmit a QOS NULL frame and asks to confirm the ACK status. Even though rtw88 confirms to mac80211 that the QOS NULL was transmitted successfully, the connection still dies. This is because rtw88 is handing the QOS NULL back to mac80211 with skb->data pointing to the headroom (the TX descriptor) instead of ieee80211_hdr. Fix the disconnection by moving skb->data to the correct position before ieee80211_tx_status_irqsafe(). The problem was observed with RTL8811AU (TP-Link Archer T2U Nano) and the potential future rtw88_8821au driver. Also tested with RTL8811CU (Tenda U9).

2024-08-03wifi: rtw89: fix HW scan not aborting properlyPo-Hao Huang2-2/+12
commit 669b692247d4516e252c898c0e7366a09d84d1be upstream. There is a length limit on the commands we send to firmware, so dividing to two commands is sometimes required when scanning. When aborting scan, we should not send second scan command to firmware after the first one is finished. This could cause some unexpected errors when we cannot receive firmware events (e.g. in suspend). Another case is scan happens before suspending, ieee80211_do_stop() is called to abort scan and driver indicate scan completion by ieee80211_scan_completed(), which queues event to scan work. But scan work might be late to execute after ieee80211_do_stop(). To correct this, driver indicates ieee80211_scan_completed() before returning, so that ieee80211_do_stop() can flush scan work properly.

commit a17b9f590f6ec2b9f1b12b1db3bf1d181de6b272 upstream. When changing the interface type we also need to update the bss_num, the driver private data is searched based on a unique (bss_type, bss_num) tuple, therefore every time bss_type changes, bss_num must also change. This fixes for example an issue in which, after the mode changed, a wireless scan on the changed interface would not finish, leading to repeated -EBUSY messages to userspace when other scan requests were sent.

[ Upstream commit b5d14b0c6716fad7f0c94ac6e1d6f60a49f985c7 ] When user issues a connection with a different SSID than the one virt_wifi has advertised, the __cfg80211_connect_result() will trigger the warning: WARN_ON(bss_not_found). The issue is because the connection code in virt_wifi does not check the SSID from user space (it only checks the BSSID), and virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS even if the SSID is different from the one virt_wifi has advertised. Eventually cfg80211 won't be able to find the cfg80211_bss and generate the warning. Fixed it by checking the SSID (from user space) in the connection code.

2024-08-03wifi: ath12k: fix peer metadata parsingKarthikeyan Periyasamy6-14/+72
[ Upstream commit 1eeafd64c7b455381b77c546e41bc267e13e2809 ] Currently, the Rx data path only supports parsing peer metadata of version zero. However, the QCN9274 platform configures the peer metadata version as V1B. When V1B peer metadata is parsed using the version zero logic, invalid data is populated, causing valid packets to be dropped. To address this issue, refactor the peer metadata version and add the version based parsing to populate the data from peer metadata correctly.

[ Upstream commit bd40215b19d255b433a91a8bb8088937e5db4284 ] When EMLSR gets unblocked, the current code checks if the last exit was due to an EXIT reason (as opposed to a BLOCKING one), and if so, it does nothing, as in this case a MLO scan was scheduled to run in 30 seconds. But the code doesn't consider the time that passed from the last exit, so if immediately after the exit a blocker occurred (e.g. non-BSS interface), and lasts for more than 30 seconds, then the MLO scan and the following link selection will decide not to enter EMLSR, and when the unblocking event finally happens, the reason is still set to the EXIT one, so it will do nothing, and we will not have the chance to re-enable EMLSR. Fix this by checking also the time that has passed since the last exit, only if it is less than 30 seconds, we can count on the scheduled MLO scan. Note that clearing the reason itself can't be done since it is needed for the EMLSR prevention mechanism.

2024-08-03wifi: ath11k: fix wrong handling of CCMP256 and GCMP ciphersBaochen Qiang3-6/+15
[ Upstream commit d2b0ca38d362ebf16ca79cd7f309d5bb8b581deb ] Currently for CCMP256, GCMP128 and GCMP256 ciphers, in ath11k_install_key() IEEE80211_KEY_FLAG_GENERATE_IV_MGMT is not set. And in ath11k_mac_mgmt_tx_wmi() a length of IEEE80211_CCMP_MIC_LEN is reserved for all ciphers. This results in unexpected management frame drop in case either of above 3 ciphers is used. The reason is, without IEEE80211_KEY_FLAG_GENERATE_IV_MGMT set, mac80211 will not generate CCMP/GCMP headers in frame for ath11k. Also MIC length reserved is wrong. Such frame is dropped later by hardware: ath11k_pci 0000:5a:00.0: mac tx mgmt frame, buf id 0 ath11k_pci 0000:5a:00.0: mgmt tx compl ev pdev_id 1, desc_id 0, status 1 From user point of view, we have observed very low throughput due to this issue: action frames are all dropped so ADDBA response from DUT never reaches AP. AP can not use aggregation thus throughput is low. Fix this by setting IEEE80211_KEY_FLAG_GENERATE_IV_MGMT flag and by reserving proper MIC length for those ciphers.

[ Upstream commit 8b2a12749b08726f006303814ecc1c37024d3617 ] Currently ACPI notification handler is installed when driver loads and only gets removed when driver unloads. During resume after firmware is reloaded, ath12k tries to install it by default. Since it is installed already, ACPI subsystem rejects it and returns an error: [ 83.094206] ath12k_pci 0000:03:00.0: failed to install DSM notify callback: 7 Fix it by removing that handler when going to suspend. This also avoid any possible ACPI call to firmware before firmware is reloaded/reinitialized.

[ Upstream commit a57ab7cced454f69b8ee8aa5f5019ea8de4674da ] When handling fragmented packets, the ath12k driver reassembles each fragment into a normal packet and then reinjects it into the HW ring. However, a firmware crash occurs during this reinjection process. The issue arises because the driver populates peer metadata in reo_ent_ring->queue_addr_lo, while the firmware expects the physical address obtained from the corresponding peer’s queue descriptor. Fix it by filling peer's queue descriptor's physical address in queue_addr_lo.

Given that arbitrary memory can be allocated to the skb buffer, knowledge about the data contained in the reinjected buffer is lacking. Consequently, there’s a risk of private information being leaked.

With some debug it is found that this is because: when system goes to suspend, ath12k_mac_op_stop() gets called where then in ath12k_mac_stop() ab->pdevs_active[ar->pdev_idx] is cleared. This results in ath12k_mac_get_ar_by_pdev_id() always returning a NULL ar, and thereby ath12k_mac_wait_tx_complete() never gets a chance to run. Fix it by retrieving ar directly from ab->pdevs[].ar instead of using ath12k_mac_get_ar_by_pdev_id(). Since ab->pdevs[].ar is set at boot time and won't get cleared when suspend, ath12k_mac_wait_tx_complete() won't be skipped. In addition, with ath12k_mac_get_ar_by_pdev_id() removed, rcu_read_lock()/unlock() are not needed any more, so remove them. This also fixes the warning above.

2024-08-03wifi: ath12k: Fix tx completion ring (WBM2SW) setup failureNithyanantham Paramasivam2-6/+14
[ Upstream commit 0ce9ab2785e4e9ca0752390d8e5ab65bd08f0e78 ] We observe intermittent ping failures from the access point (AP) to station (STA) in any mode (AP-STA or Mesh) configured. Specifically, the transmission completion status is not received at tx completion ring id 4 (WBM2SW ring4) for the packets transmitted via TCL DATA ring id 3. This prevents freeing up tx descriptors and leads to buffer exhaustion. Currently, during initialization of the WBM2SW ring, we are directly mapping the ring number to the ring mask to obtain the ring mask group index. This approach is causing setup failures for WBM2SW ring 4. Similarly, during runtime, when receiving incoming transmission completion status, the validation of the ring number by mapping the interrupted ring mask. This is resulting in validation failure. Thereby preventing entry into the completion handler ath12k_dp_tx_completion_handler(). The existing design assumed that the ring numbers would always be sequential and could be directly mapped with the ring mask. However, this assumption does not hold true for WBM2SW ring 4. Therefore, modify the design such that, instead of mapping the ring number, the ring ID is mapped with the ring mask. According to this design: 1. During initialization of the WBM2SW ring, mapping the ring ID to the ring mask will ensure obtaining the correct ring mask group ID. 2. During runtime, validating the interrupted ring mask group ID within the transmission completion group is sufficient. This approach allows the ring ID to be derived from the interrupted ring mask and enables entry into the completion handler.

NL80211_CMD_PROBE_CLIENT is used for this purpose. And the skb will be added to ack_status_frame - waiting for a completion via ieee80211_report_ack_skb(). But when the peer was already removed before the tx_complete arrives, the peer will be missing. And when using dev_kfree_skb_any (instead of going through mac80211), the entry will stay inside ack_status_frames thus not clean up related information in its internal data structures. This IDR will therefore run full after 8K request were generated for such clients. At this point, the access point will then just stall and not allow any new clients because idr_alloc() for ack_status_frame will fail. ieee80211_free_txskb() on the other hand will (when required) call ieee80211_report_ack_skb() and make sure that (when required) remove the entry from the ack_status_frame and clean up related information in its internal data structures.

2024-07-24thermal: core: Allow thermal zones to tell the core to ignore themRafael J. Wysocki1-1/+6
commit e528be3c87be953b73e7826a2d7e4b837cbad39d upstream. The iwlwifi wireless driver registers a thermal zone that is only needed when the network interface handled by it is up and it wants that thermal zone to be effectively ignored by the core otherwise. Before commit a8a261774466 ("thermal: core: Call monitor_thermal_zone() if zone temperature is invalid") that could be achieved by returning an error code from the thermal zone's .get_temp() callback because the core did not really handle errors returned by it almost at all. However, commit a8a261774466 made the core attempt to recover from the situation in which the temperature of a thermal zone cannot be determined due to errors returned by its .get_temp() and is always invalid from the core's perspective. That was done because there are thermal zones in which .get_temp() returns errors to start with due to some difficulties related to the initialization ordering, but then it will start to produce valid temperature values at one point. Unfortunately, the simple approach taken by commit a8a261774466, which is to poll the thermal zone periodically until its .get_temp() callback starts to return valid temperature values, is at odds with the special thermal zone in iwlwifi in which .get_temp() may always return an error because its network interface may always be down. If that happens, every attempt to invoke the thermal zone's .get_temp() callback resulting in an error causes the thermal core to print a dev_warn() message to the kernel log which is super-noisy. To address this problem, make the core handle the case in which .get_temp() returns 0, but the temperature value returned by it is not actually valid, in a special way. Namely, make the core completely ignore the invalid temperature value coming from .get_temp() in that case, which requires folding in update_temperature() into its caller and a few related changes. On the iwlwifi side, modify iwl_mvm_tzone_get_temp() to return 0 and put THERMAL_TEMP_INVALID into the temperature return memory location instead of returning an error when the firmware is not running or it is not of the right type. Also, to clearly separate the handling of invalid temperature values from the thermal zone initialization, introduce a special THERMAL_TEMP_INIT value specifically for the latter purpose.

2024-06-18wifi: wlcore: fix wlcore AP modeRussell King (Oracle)4-21/+16
Using wl183x devices in AP mode with various firmwares is not stable. The driver currently adds a station to firmware with basic rates when it is first known to the stack using the CMD_ADD_PEER command. Once the station has finished authorising, another CMD_ADD_PEER command is issued to update the firmware with the rates the station can use. However, after a random amount of time, the firmware ignores the power management nullfunc frames from the station, and tries to send packets while the station is asleep, resulting in lots of retries dropping down in rate due to no response. This restricts the available bandwidth. With this happening with several stations, the user visible effect is the latency of interactive connections increases significantly, packets get dropped, and in general the WiFi connections become unreliable and unstable. Eventually, the firmware transmit queue appears to get stuck - with packets and blocks allocated that never clear. TI have a couple of patches that address this, but they touch the mac80211 core to disable NL80211_FEATURE_FULL_AP_CLIENT_STATE for *all* wireless drivers, which has the effect of not adding the station to the stack until later when the rates are known. This is a sledge hammer approach to solving the problem. The solution implemented here has the same effect, but without impacting all drivers. We delay adding the station to firmware until it has been authorised in the driver, and correspondingly remove the station when unwinding from authorised state. Adding the station to firmware allocates a hlid, which will now happen later than the driver expects. Therefore, we need to track when this happens so that we transmit using the correct hlid. This patch is an equivalent fix to these two patches in TI's wilink8-wlan repository: https://git.ti.com/cgit/wilink8-wlan/build-utilites/tree/patches/kernel_patches/4.19.38/0004-mac80211-patch.patch?h=r8.9&id=a2ee50aa5190ed3b334373d6cd09b1bff56ffcf7 https://git.ti.com/cgit/wilink8-wlan/build-utilites/tree/patches/kernel_patches/4.19.38/0005-wlcore-patch.patch?h=r8.9&id=a2ee50aa5190ed3b334373d6cd09b1bff56ffcf7 Reported-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Co-developed-by: Johannes Berg <johannes.berg@intel.com> Tested-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/E1sClp4-00Evu7-8v@rmk-PC.armlinux.org.uk
