2025-11-12wifi: iwlwifi: mld: always take beacon ies in link gradingMiri Korenblit
One of the factors of a link's grade is the channel load, which is calculated from the AP's bss load element. The current code takes this element from the beacon for an active link, and from bss->ies for an inactive link. bss->ies is set to either the beacon's ies or to the probe response ones, with preference to the probe response (meaning that if there was even one probe response, the ies of it will be stored in bss->ies and won't be overiden by the beacon ies). The probe response can be very old, i.e. from the connection time, where a beacon is updated before each link selection (which is triggered only after a passive scan). In such case, the bss load element in the probe response will not include the channel load caused by the STA, where the beacon will. This will cause the inactive link to always have a lower channel load, and therefore an higher grade than the active link's one. This causes repeated link switches, causing the throughput to drop. Fix this by always taking the ies from the beacon, as those are for sure new.

2025-10-28wifi: iwlwifi: mld: reschedule check_tpt_wk also not in EMLSRMiri Korenblit
When the throughput count reaches the threshold, EMLSR is no longer blocked by throughput. This doesn't mean that EMLSR will be activated immediately, since there might be other reasons that block EMLSR. When the throughput blocker is not set, check_tpt_wk should run every 5 seconds and check if the throughput blocker should be set (if the throughtput counter dropped). If not, it should reschedule itself. In the current code, the worker will reschedule itself only if we are in EMLSR. This is wrong, since we might be in a case where the throughput blocker is not set but we are not in EMLSR, and then we will never check again the throughput counters (and block EMLSR if needed). Fix this by rescheduling the worker also when EMLSR is not active.

In suspend and resume flows, if we had any error we set the transport state to 'FW_ERROR' This was done to avoid sending commands when we shouldn't. In the mentioned flows, we can have a few types of errors: 1. logic errors 2. FW is in error state (can't send commands) 3. FW is misbehaving 4. D3 handshake error In the first, we can still talk to the firmware. In the second - the transport already knows about the FW error, no need to tell it. In the third - we need to treat it as any other FW misbehaviour. There is no reason to have a special handling here. So we only need it for the last type.

If iwl_trans_d3_resume succeeded but the hw requested a reset, this will be indicated to the opmode via the iwl_d3_status parameter while the return value will be 0. But the opmode doesn't really care if the resume failed or if a restart is required. It acts the same in both cases (beside different logs, but this can be done in iwl_trans_pcie_d3_resume) This complicates the code for no good reason. Change the iwl_trans_pcie_d3_resume to return an error value also in the case that everything went successfully but a restart is required, and add more logs so we can differentiate between the cases.

When beacon loss happens or the RSSI drops, trigger MLO scan only if not in EMLSR. The link switch was meant to be done when we are not in EMLSR and we can try to switch to a better link. If in EMLSR, we exit first and then trigger MLO scan.

2025-08-28wifi: iwlwifi: mld: don't check the cipher on resumeMiri Korenblit
On resume, we are iterating all the keys in order to update the PN. Currently we check the cipher of the key we are currently iterating on to decide whether the key is PTK, GTK, IGTK or BIGTK. But we can find the type of the key by the keyidx, and we anyway have to check the keyidx, so just remove the cipher switch case and check only the keyidx instead Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Miri Korenblit <miriam.rachel.korenblit@intel.com> Link: https://patch.msgid.link/20250826184046.8c4f9c30242c.Ie34c200f321aae60771476fa9907c333a8a99747@changeid
2025-08-26wifi: iwlwifi: mld: don't validate keys state on resumeMiri Korenblit
When resuming, we iterate over all the (installed) keys to update the PNs. If we find a key with an unexpected cipher we disconnect. But there is no reason for us to validate the internal key state specifically on resume, it should be the same as it was before the suspend. Remove the 'unhandled_cipher' from the iteration data. Also remove the num_keys indication as it is not really needed. If no keys were installed before the suspend, we will have num_of_gtk_rekeys = 0 and we will return early anyway.

2025-08-26wifi: iwlwifi: mld: don't consider old versions of PPAGMiri Korenblit
There is a utility function, iwl_fill_ppag_table, to fill the PPAG table according the version of the FW API and on of the BIOS table. But this function handles really old APIs that iwlmld will not support. Also, iwlmvm will no longer have new APIs of PPAG (because it is loaded on frozen devices only). So in the next versions we might introdue regressions to iwlmvm. Simply fill the PPAG table separately in iwlmld code, without using this utility.

2025-08-26wifi: iwlwifi: mld/mvm: set beacon protection capability in wowlan configMiri Korenblit
Although the FW knows if a BIGTK was installed and can conclude from that the beacon protection capability, the specific component of the FW that is responsible for rekeying while in wowlan, doesn't know what keys were installed. So we need to tell that the FW when we go to wowlan, otherwise it will ignore the BIGTK rekey, if such occurs. Set this bit when needed.

2025-08-26wifi: iwlwifi: mvm/mld: correctly retrieve the keyidx from the beaconMiri Korenblit
key->icv_len already includes the pn length and the keyidx length. In fact it is the size of the MMIE, so subtracting it from the overall length will actually bring us to the beggining of the MMIE and not of the keyidx inside it. Also, we also need to consider a 16 byte long MIC. Fix the code to correctly retrieve the keyidx.
