After -Wstringop-overflow got enabled, the rtw89 driver produced two odd warnings with gcc-13: drivers/net/wireless/realtek/rtw89/coex.c: In function 'rtw89_btc_ntfy_scan_start': drivers/net/wireless/realtek/rtw89/coex.c:5362:50: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=] 5362 | wl->dbcc_info.scan_band[phy_idx] = band; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~ In file included from drivers/net/wireless/realtek/rtw89/coex.h:8, from drivers/net/wireless/realtek/rtw89/coex.c:5: drivers/net/wireless/realtek/rtw89/core.h:1441:12: note: at offset [64, 255] into destination object 'scan_band' of size 2 1441 | u8 scan_band[RTW89_PHY_MAX]; /* scan band in each phy */ | ^~~~~~~~~ drivers/net/wireless/realtek/rtw89/coex.c: In function 'rtw89_btc_ntfy_switch_band': drivers/net/wireless/realtek/rtw89/coex.c:5406:50: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=] 5406 | wl->dbcc_info.scan_band[phy_idx] = band; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~ drivers/net/wireless/realtek/rtw89/core.h:1441:12: note: at offset [64, 255] into destination object 'scan_band' of size 2 1441 | u8 scan_band[RTW89_PHY_MAX]; /* scan band in each phy */ | ^~~~~~~~~ I don't know what happened here, but adding an explicit range check shuts up the output.

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 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.

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:

When enter suspend/resume while in a connected state, the upper layer will trigger disconnection before entering suspend, and at the same time, it will trigger regd_notifier() and update CLC, causing the CLC event to not be received due to suspend, resulting in a command timeout. Therefore, the update of CLC is postponed until resume, to ensure data consistency and avoid the occurrence of command timeout.

Due to the increase in the number of power tables for 6Ghz on CLC, the variable nr_country is no longer sufficient to represent the total quantity.

We actually don't need the reserve the 512 entries for the MCU firmware download Rx queue because the queue was only used in the firmware download phase to save the most of space and the reduction can significantly help with reducing latency we spent by ~20% further in resetting the Rx queue as the device was waking up from deep sleep mode.

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.

The ieee80211_queue_work function queues work into the mac80211 local->workqueue, which is widely used for mac80211 internal work processes. In the mt76 driver, both the mt76-sido-status and mt76-sdio-net threads enqueue workers to the workqueue with this function. However, in some cases, when two workers are enqueued to the workqueue almost simultaneously, the second worker may not be scheduled immediately and may get stuck for a while. This can cause timing issues. To avoid these timing conflicts caused by worker scheduling, replace the worker with an independent thread.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert the three mt76 drivers from always returning zero in the remove callback to the void returning variant. Signed-off-by:
