If the hardware supports a disabled channel, it may in some cases be possible to use monitor mode (without any transmit) on it when it's otherwise disabled. Add a new channel flag IEEE80211_CHAN_CAN_MONITOR that makes it possible for a driver to indicate such a thing. Make it per channel so drivers could have a choice with it, perhaps it's only possible on some channels, perhaps some channels are not supported at all, but still there and marked disabled. In _nl80211_parse_chandef() simplify the code and check only for an unknown channel, _cfg80211_chandef_usable() will later check for IEEE80211_CHAN_DISABLED anyway. Signed-off-by:

This allows testing 160MHz channels with DFS concurrent. While at it, remove the TODO for adding a module param to enable NL80211_EXT_FEATURE_DFS_CONCURRENT. This is not really needed as mac80211_hwsim still needs to be loaded with custom regdom. Signed-off-by:

Currently, whenever AP link is brought down via ieee80211_stop_ap() function, all stations connected to the sdata are flushed. However, in case of MLO there is a requirement to flush only stations connected to that link and not all. For instance - Consider 2 GHz and 5 GHz are AP MLD. Now due to some reason 5 GHz link of this AP is going down (link removal or any other case). All stations connected, even legacy stations connected to 2 GHz link AP would also be flushed. Flushing of other link stations is not desirable. Fix this issue by passing self link ID to sta_flush() function. This would then only remove the stations which are still using the passed link ID as their link sta. Other stations will not be affected. Signed-off-by:

Whenever sta_flush() function is invoked, all STAs present in that interface are flushed. In case of MLO, it is desirable to only flush such STAs that are at least using a given link id as one of their links. Add support for this by making change in the __sta_info_flush API argument to accept a link ID. And then, only if the STA is using the given link as one of its links, it would be flushed.

Currently whenever NL80211_CMD_DEL_STATION command is called without any MAC address, all stations present on that interface are flushed. However with MLO there is a need to flush such stations only which are using at least a particular link from the AP MLD interface. For example - 2 GHz and 5 GHz are part of an AP MLD. To this interface, following stations are connected - 1. One non-EHT STA on 2 GHz link. 2. One non-EHT STA on 5 GHz link. 3. One Multi-Link STA having 2 GHz and 5 GHz as active links. Now if currently, NL80211_CMD_DEL_STATION is issued by the 2 GHz link without any MAC address, it would flush all station entries. However, flushing of station entry #2 at least is not desireable since it is connected to 5 GHz link alone. Hence, add an option to pass link ID as well in the command so that if link ID is passed, stations using that passed link ID alone would be flushed and others will not. So after this, station entries #1 and #3 alone would be flushed and #2 will remain as it is. Signed-off-by:

Since WiFi 7 is expected to support MLO, so we should enable MAC-0/1 and PHY-0/1. By default, set dbcc_en=true, change quota to DBCC mode, and set MLO mode to 2 + 0 that means we only use 2x2 connection on MAC/PHY-0 for now. Signed-off-by:

wifi: mwifiex: Refactor 1-element array into flexible array in struct mwifiex_ie_types_chan_list_param_set struct mwifiex_ie_types_chan_list_param_set::chan_scan_param is treated as a flexible array, so convert it into one so that it doesn't trip the array bounds sanitizer[1]. Only a few places were using sizeof() on the whole struct, so adjust those to follow the calculation pattern to avoid including the trailing single element. Examining binary output differences doesn't appear to show any literal size values changing, though it is obfuscated a bit by the compiler adjusting register usage and stack spill slots, etc. Link: https://github.com/KSPP/linux/issues/51 [1] Cc: Brian Norris <briannorris@chromium.org> Cc: Kalle Valo <kvalo@kernel.org> Cc: Dmitry Antipov <dmantipov@yandex.ru> Cc: Johannes Berg <johannes.berg@intel.com> Cc: zuoqilin <zuoqilin@yulong.com> Cc: Ruan Jinjie <ruanjinjie@huawei.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Cc: Gustavo A.

Document ATWILC1000/ATWILC3000 Baremetal Wi-Fi/BLE Link Controller Software Design Guide https://tinyurl.com/yer2xhyc says that bit 0 of the CRC7 code must always be a 1. I confirmed that today with a logic analyzer: setting bit 0 causes wilc1000 to accept a command with CRC7 enabled, whereas clearing bit 0 causes wilc1000 to reject the command with a CRC error.

During mac80211 reconfig, chanctx ops of multiple channels might not be called in order as normal cases. However, we expect the first active chanctx always to be put at our sub entity index 0. So, if it does not, we do a swap there. Besides, reconfig won't allocate a new chanctx object. So, we should reset the reference count when ops add chanctx. Signed-off-by:

After MLO, we will need to consider not only active chanctx but also active interfaces (roles) to decide entity things. So in advance, we move handling from chanctx_ops::add/remove to chanctx_ops::assign_vif/unassign_vif. Then, we can recalculate and aware active interfaces' changes. For now, behavior should not be really different, since active chanctx and active interface are one-to-one mapping before MLO. Signed-off-by:

Originally, we consider weight only based on how many chanctxs that mac80211 sets. However, we need to consider both active chanctxs and active interfaces to distinguish MCC (multiple channel concurrent) from impending MLO. Although the logic of handling is extended, for now, behavior might not be different under current condition. Signed-off-by:

Originally, we just declared two sub-entity, and according to rolling down mechanism, we ensured that index 0 contained sub-entity as long as there are sub-entity. So, we could use for-loop after deciding the last index. But, we are preparing to expand num of sub-entity for MLO. Then, there won't be just two sub-entity. And, there might be holes between two bits in the bitmap. So, we cannot simply do for-loop as before. Instead, we need to follow the set bits. Signed-off-by:

Originally, we replaced sub-entity of index 0 with another one in some cases. However, we will need a swap here in following implementations. So, we introduce it ahead and change code from replacing to swapping. Signed-off-by:

Some of our calculation during concurrent mode depend on last beacon TSF. Originally, we just set IEEE80211_HW_TIMING_BEACON_ONLY and get what we want from mac80211. But, IEEE80211_HW_TIMING_BEACON_ONLY will be restricted once we declare MLO. Since we are about to consider the MLO stuffs, so sync beacon TSF by ourselves now and unset IEEE80211_HW_TIMING_BEACON_ONLY. Signed-off-by:

WILC driver currently applies some default configuration whenever the firmware is initialized, and sets the default preamble size to short. However, despite this passed option, firmware is also able to successfully connect to access points only using long preamble, so this setting does not really enforce short preambles and is misleading regarding applied configuration. Update default configuration and make it match the firmware behavior by passing the existing WILC_FW_PREAMBLE_AUTO value (2 instead of 0). The updated setting does not really alter firmware behavior since it is still capable to connect to both short preamble and long preamble access points, but at list the setting now expresses for real the corresponding firmware behavior. More info: it has been implemented to address the transmission (Tx) blackout issue observed in the 802.11b mode. The modification has no impact on the other modes, which will continue to work as they did in the previous implementation. This change will allow the 802.11b transmission (2, 5.5, 11Mbps) to use long preamble. Signed-off-by:

The firmware (later) actually uses the values even for keys that are invalid as far as the host is concerned, later in rekeying, and then only sets the low 48 bits since the PNs are only 48 bits over the air. It does, however, compare the full 64 bits later, obviously causing problems. Remove the memset and use kzalloc instead to avoid any old heap data leaking to the firmware. We already init all the other fields in the struct anyway. This leaves the data set to zero for any unused fields, so the firmware can look at them safely even if they're not used right now.
