The WARN_ON() in subject was actually seen only once, with 5.10.200 under syzkaller. It looks like a weird artifact of (ab?)using the syzkaller itself [1], and hopefully may be safely removed.

The ESS capability bit is reserved in frames transmitted by the client, so we shouldn't set it. Since we've set it for decades, keep that old behaviour unless we're connection to a new EHT AP. Signed-off-by:

When doing a channel switch, cfg80211_update_known_bss may be called with a BSS where both proberesp_ies and beacon_ies is set. If that happens, both need to be consumed. Signed-off-by:

The specification says that this information should not be explicitly included in the per-STA profile. However, we need this information readily available in the BSS for userspace and also internally when associating. As such, append the appropriate element before adding/updating the BSS.

There may be cases where puncturing isn't possible, and a connection needs to be downgraded. Add a hardware flag to support this. This is likely temporary: it seems we will need to move puncturing to the chandef/channel context. Signed-off-by:

Add support for setting the TID to link mapping for a non-AP MLD station. This is useful in cases user space needs to restrict the possible set of active links, e.g., since it got a BSS Transition Management request forcing to use only a subset of the valid links etc. Signed-off-by:

With the locking rework, more functions need to be called with the wiphy mutex held. Document that, and for that use the "Context" description that shows up more nicely in the generated documentation. Signed-off-by:

Johannes Berg authored
Sometimes there may be reasons for which a BSS that's actually found in scan cannot be used to connect to, for example a nonprimary link of an NSTR mobile AP MLD cannot be used for normal direct connections to it. Not indicating these to userspace as we do now of course avoids being able to connect to them, but it's better if they're shown to userspace and it can make an appropriate decision, without e.g. doing an additional ML probe. Thus add an indication of what a BSS can be used for, currently "normal" and "MLD link", including a reason bitmap for it being not usable. The latter can be extended later for certain BSSes if there are other reasons they cannot be used. Signed-off-by:

There's only one user of this code, which is STA unblock during sleep for uAPSD on really old devices. Instead of having this all through the API with calls up and down, just implemented a special-case CMD_BLOCK_TXQS flag for this, it's only needed in the old gen1 transport. While at it, fix a complain that lockdep would have, as we lock the cmd queue and then the TXQs in the reclaim by using spin_lock_nested(). We no longer need to disable BHs in iwl_trans_pcie_block_txq_ptrs() since it's called with them disabled already. Signed-off-by:

When there's not going to be any data in the data event, we don't need to add it at all (unlike the TX version, it has no data at all.) Also combine the tracing into a separate inline so we only call iwl_rx_trace_len() once, which also simplifies things, and lets us have a single place to later add other checks. Signed-off-by:

Current handling of del pmksa with SSID is limited to FILS security. In the current change the del pmksa support is extended to SAE/OWE security offloads as well. For OWE/SAE offloads, the PMK is generated and cached at driver/FW, so user app needs the capability to request cache deletion based on SSID for drivers supporting SAE/OWE offload. Signed-off-by:

To support the WBRF mechanism, Wifi adapters utilized in the system must register the frequencies in use (or unregister those frequencies no longer used) via the dedicated calls. So that, other drivers responding to the frequencies can take proper actions to mitigate possible interference. Co-developed-by:

Due to electrical and mechanical constraints in certain platform designs there may be likely interference of relatively high-powered harmonics of the (G-)DDR memory clocks with local radio module frequency bands used by Wifi 6/6e/7. To mitigate this, AMD has introduced a mechanism that devices can use to notify active use of particular frequencies so that other devices can make relative internal adjustments as necessary to avoid this resonance.

To diagnose the reason why firmware or hardware get abnormal, add to dump MAC registers related to counters and interrupt masks. With these values, people can classify problems and check if registers values are unexpected, and then correct them. However, it could possible false alarm because firmware triggers this SER event by wrong conditions that we should correct it at firmware or register settings. In field, SER might happen under special conditions, and very hard to happen again, so dump lots of registers to provide rich information to catch the problem. Signed-off-by:

RTL8922A FW supports CRASH_TRIGGER feature from v0.34.30.0. After it, debugfs fw_crash can accept type 1 on RTL8922A to trigger firmware crash and verify L2 recovery. Besides, RTL8922A sync address offset of reserved payload engine. And, SER (system error recovery) tweaks conversion from WCPU address to indirect access address for RTL8922A. The new conversion works for all supported chips. Signed-off-by:

In concurrent mode, when STA interface is scanning, it causes AP interface TX beacon on wrong channel. We modified it to scan with the operating channel when one of the interfaces is already connected. Additionally, STA interface need to stop scan when AP interface is starting to avoid TX beacon on wrong channel. Finally, AP interface need to stop TX beacon when STA interface is scanning and switching to non-OP channel,This prevent other device to get beacons on wrong channel. Signed-off-by:

We add a scanning check to avoid entering IPS after ROC (remain on channel) during scanning. Additionally, When P2P scanning, the flow is `1. p2p_listen step` and `2. configure filter` and `3. p2p_scan starts` in wpas, but in kernel, cfg80211 uses another workqueue to notify driver the filter change, so sometimes we see (1 > 3 > 2), that will cause Rx filter related to scan to be cleared. Therefore, we add a scanning check when configure filter to avoid scan results to be filtered. Finally, we cancel the ROC delayed workqueue before entering ROC to avoid entering twice, which might cause leaving ROC too early. Signed-off-by:
