2026-04-08wifi: ipw2x00: Use michael_mic() from cfg80211Eric Biggers-116/+5

2026-04-08wifi: ipw2x00: Rename michael_mic() to libipw_michael_mic()Eric Biggers-3/+3
Rename the driver-local michael_mic() function to libipw_michael_mic() to prevent a name conflict with the common michael_mic() function. Note that this code will be superseded later when libipw starts using the common michael_mic(). This commit just prevents a bisection hazard.

Do not latch these flags, they should be re-evaluated for each iteration of the loop. Concretely, rxq->free_count is incremented during the loop so the __GFP_NOWARN decision may be stale.

Fix 2 issues spotted by AI[0]: 1. Missing space after the full stop. 2. Wrong GFP flags are printed. And also switch to %pGg for the GFP flags.

2026-03-25wifi: iwlwifi: mld: update the TLC when we deactivate a linkEmmanuel Grumbach-1/+56
We hit a problem in the channel switch flow. We had link 0 using PHY 0, so the TLC object in the firmware is using PHY 0. Then we switched channel, so mac80211 / iwlmld: * deactivated link 0 * removed PHY 0 * added PHY 1 * modified link 0 to use PHY 1 * activated link 0. The TLC object was not updated and the firmware was unhappy that the TLC was still trying to use PHY 0. Fix that by letting the TLC know about the PHY context before the link activation. When we are de-activating a link, let the TLC know so that it'll send a TLC configuration command with an invalid PHY context to remove the relationship between the TLC object and the PHY that is going to be removed. That last part is not implemented yet in the firmware, so leave this as a TODO for now.

2026-03-25wifi: iwlwifi: mld: always assign a fw id to a vifMiri Korenblit-0/+5
We used to have a fw id assignment in iwl_mld_init_vif since all interface types that were added to the driver was immediately added to the FW as well. Since NAN was introduced, this is no longer the case - the NAN interface is not added to the fw until a local schedule is configured. For this vif we don't assign a fw id so it is 0 by default. But later, when the vif is removed from the driver, we think that it has a valid fw id (0) and we point fw_id_to_vif[0] to NULL. fw_id_to_vif[0] might actually point to another vif with a valid fw id 0. In this case, we end up messing fw_id_to_vif. Fix this by initializing a vif with a special invalid fw id, and by exiting iwl_mld_rm_vif early for NAN interfaces.

2026-03-25wifi: iwlwifi: mld: use the dedicated helper to extract a linkMiri Korenblit-6/+3
There is a helper, iwl_mld_fw_id_to_link_conf, that converts a fw link id into the bss_conf structure. Use it in two more places instead of retrieving the bss_conf directly from the fw-id-to-bss_conf mapping array. This required changing the loop bound in iwl_mld_process_per_link_stats() to ucode_capa.num_links, to avoid hitting a IWL_FW_CHECK for link ids > ucode_capa.num_links and < ARRAY_SIZE(fw_id_to_bss_conf), but this change makes sense anyway (there is no reason to iterate links that cannot be valid).

2026-03-25wifi: iwlwifi: uefi: open code the parsing of the WGDS tableEmmanuel Grumbach-7/+44
We will soon add support for UNII-9 band in the WGDS table. We need to decouple the UEFI code from the firmware runtime code. The firmware runtime is just a software object which will need to grow and UEFI objects need a new revision to grow. Existing systems will keep the same UEFI objects. Just like PPAG and SAR, stop using structures to parse the UEFI tables since the layout depends on the revision. The support for the new revision will be added in the next patch, for now, just do the ground work.

Those tables now have support for UNII-9 subband. Refactor iwl_uefi_set_sar_profile to get an array of values that makes it easier to use when the number of subbands can vary. Revamp a bit the code that fetches the tables to ask for the smaller table, then we can check the size of the object that we got and compare to the expected sizes to determine what revision to expect.
