2023-10-23wifi: iwlwifi: mvm: remove set_tim callback for MLD opsJohannes Berg1-2/+0
In new firmware, we don't need this any more and it won't be called any more by mac80211, since powersave handling is all done by firmware. Remove it from the MLD ops.

2023-10-23wifi: iwlwifi: make time_events MLO awareMiri Korenblit1-1/+2
As session protection API is moving to be per link instead of per mac, move the time events to be per link too. Since there is only one concurrent time event per mac, it feels unnecessary to have the time_event as a member of iwl_mvm_link_info. (That way we will have to iterate over all links each time we want to clear a time event, and also we will need mac80211 to tell us the link id when mgd_tx_complete() is called.) So leave this as a member of iwl_mvm_vif, but add the link id to the time_event structure. The link id in time_event will only be maintained and used for: 1. When SESSION_PROTECTION_CMD is supported (before it, we don't have MLO) 2. For time_events of types SESSION_PROTECT_CONF_ASSOC, SESSION_PROTECT_CONF_P2P_DEVICE_DISCOV, and SESSION_PROTECT_CONF_P2P_GO_NEGOTIATION (not for aux roc/ Hot Spot time_events). For P2P, non-MLO connections, and pre-MLD API, deflink id, meaning 0, will be used Signed-off-by: Miri Korenblit <[email protected]> Signed-off-by: Gregory Greenman <[email protected]> Link: https://lore.kernel.org/r/20231017115047.21496bcacb18.I79d037325b4fae4c12a22d9477e53fc9c537ad46@changeid Signed-off-by: Johannes Berg <[email protected]>
2023-10-23wifi: iwlwifi: mvm: change iwl_mvm_flush_sta() APIJohannes Berg1-1/+1
This API is type unsafe and needs an extra parameter to know what kind of station was passed, so it has two, but really it only needs two values. Just pass the values instead of doing this type-unsafe dance, which will also make it better to use for multi-link.

2023-10-23wifi: iwlwifi: mvm: cleanup MLO and non-MLO unification codeMiri Korenblit1-35/+4
bss_info_changed() callback of mac80211 was originally in both MLD and non-MLD API. Therefore, we extracted the common part to a function which receives a callback structure with the mode-specific (non-MLO\MLO) ops. Eventually, for MLO API, bss_info_changed() callback was split into 2 callbacks: link_info_changed() and vif_cfg_changed() so it is no longer in use for MLO, only for non-MLO. Remove the code that uses the mode-specific callback structure.

2023-10-23wifi: iwlwifi: mvm: Add basic link selection logicIlan Peer1-0/+2
Add simple logic that would allow using EMLSR in case there are multiple valid links: - In case the connection establishment has just been completed try to find a valid link pair for EMLSR functionality where one of the links in the pair is the current active link. - In case the valid links changed after connection was already established, try to find a valid link pair for EMLSR functionality, in case the EMSLR is not active yet. If a valid link pair is found call mac80211 to asynchronously set the new link pair, otherwise continue using the current active links.

2023-10-23wifi: iwlwifi: mvm: add a per-link debugfsMiri Korenblit1-0/+4
Add a per-link debugfs entry in iwlmvm level so we can read/write link related parameters. Do it by implementing the link_add_debugfs API introduced by mac80211. Each entry will have a path like this: .../netdev:wlan0/link-X/iwlmvm/<file_name> for each link X. For non-MLD vifs this callback is called when the original vif debugfs dir is also created, so handle that case by not creating the 'iwlmvm' directory again. Note that we don't have to worry about the cleaning the iwlmvm/* directory as it is already done by mac80211 when removing the link (or netdev).

2023-10-23wifi: iwlwifi: mvm: rework debugfs handlingJohannes Berg1-4/+5
mac80211 added a new callback to add a vif debugfs. Implement it instead of adding the debugfs directly, which will make it properly preserved over switching the vif from non-MLD/MLD and back.

2023-09-25wifi: iwlwifi: mvm: support set_antenna()Emmanuel Grumbach1-6/+23
set_antenna() is supported only when the device is not started in mac80211 which translates to the firmware not being loaded in iwlwifi. The tricky part is that iwlwifi populates the sband data during its boot and doesn't touch this data afterwards, but if the antenna settings forbid MIMO, we need to update the sband data. Rework the nvm parsing code to allow to get an existing nvm_data and modify the sband with additional constraints (tx / rx chains masks).

2023-09-13wifi: iwlwifi: mvm: enable FILS DF Tx on non-PSC channelShaul Triebitz1-0/+2
If the channel bandwidth is greater or equal than 80MHz, enable FILS DF transmittion, even if the control channel is non-PSC. That's because that in 80MHz there must be a sub 20MHz PSC channel, and since the FILS DF is duplicated on all sub 20MHz channels, within the 80MHz (hence it will be sent on a PSC channel). Also, if FILS DF Tx is enabled, always configure the firmware with the actual channel bandwidth, even before there is a connected client (rather than the minimum bandwidth e.g. 20MHz), since FILS DF transmission on a PSC channel take presedent over power consumption.

2023-07-11wifi: iwlwifi: remove 'use_tfh' config to fix crashJohannes Berg1-1/+1
This is equivalent to 'gen2', and it was always confusing to have two identical config entries. The split config patch actually had been originally developed after removing 'use_tfh" and didn't add the use_tfh in the new configs as they'd later been copied to the new files. Thus the easiest way to fix the init crash here now is to just remove use_tfh (which is erroneously unset in most of the configs now) and use 'gen2' in the code instead. There's possibly still an unwind error in iwl_txq_gen2_init() as it crashes if TXQ 0 fails to initialize, but we can deal with it later since the original failure is due to the use_tfh confusion.

2023-04-20wifi: iwlwifi: modify scan request and results when in link protectionAvraham Stern1-0/+25
When CSME is connected and has link protection set, the driver must connect to the same AP CSME is connected to. When in link protection, modify scan request parameters to include only the channel of the AP CSME is connected to and scan for the same SSID. In addition, filter the scan results to include only results from the same AP. This will make sure the driver will connect to the same AP and will do it fast enough to keep the session alive.

2023-04-14wifi: iwlwifi: mvm: Fix setting the rate for non station casesIlan Peer1-0/+3
The setting of the rate used for non station cases did not take into consideration the interface type etc., thus when probe responses are transmitted on P2P Device interface etc. CCK rates were used which is not allowed. Modify the code so the non station case would consider the interface type etc. For HWs/FWs that do not support rate control, preserve the previous behavior, i.e., take the rate from the skb metadata and adjust as needed.

Instead of relying on the AP STA ID and dereferencing our firmware -> mac80211 STA array when we really only need the STA, not the per-link information (and might not have it, e.g. for a pairwise key installation where this is relevant), keep track of the AP STA as a pointer to the mac80211 STA, protected by the mutex. Then use it here in the key code instead.

Add a fw_id_to_link_sta array in mvm to track the link STA for each firmware station ID, and then use that to report the link a frame was received on (since we know the station ID from firmware). Notably, this fixes beacon tracking for the correct link since mac80211 now queues and processes those on the one link identified by the link ID only.
