2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-11-07wifi: iwlwifi: mvm: tell iwlmei when we finished suspendingEmmanuel Grumbach
Since we no longer shut down the device in suspend, we also no longer call iwl_mvm_mei_device_state() and this is a problem because iwlmei expects this to be called when it runs its own suspend sequence. It checks mei->device_down in iwl_mei_remove() which is called upon suspend. Fix this by telling iwlmei when we're done accessing the device. When we'll wake up, the device should be untouched if CSME didn't use it during the suspend time. If CSME used it, we'll notice it through the CSR_FUNC_SCRATCH register.

2024-10-25wifi: iwlwifi: mvm: fix 6 GHz scan constructionJohannes Berg
If more than 255 colocated APs exist for the set of all APs found during 2.4/5 GHz scanning, then the 6 GHz scan construction will loop forever since the loop variable has type u8, which can never reach the number found when that's bigger than 255, and is stored in a u32 variable. Also move it into the loops to have a smaller scope. Using a u32 there is fine, we limit the number of APs in the scan list and each has a limit on the number of RNR entries due to the frame size. With a limit of 1000 scan results, a frame size upper bound of 4096 (really it's more like ~2300) and a TBTT entry size of at least 11, we get an upper bound for the number of ~372k, well in the bounds of a u32.

Revert commit dfdfe4be183b ("wifi: iwlwifi: remove retry loops in start"), it turns out that there's an issue with the PNVM load notification from firmware not getting processed, that this patch has been somewhat successfully papering over.

We will later at least clean this up to only attempt to retry if there was a timeout, but currently we don't even bubble up the failure reason to the correct layer, only returning NULL.

We take care of this but if link 0 is a valid MLO link, then we will re-create a default link on mvmvif->link[0] and we'll loose the real link we had there. In non-MLO, we need to re-create the default link upon the interface creation, this is fine. In MLO, we'll just wait for change_vif_links() to re-build the links.

2024-10-23wifi: mac80211: re-order assigning channel in activate linksAditya Kumar Singh
The current flow in _ieee80211_set_active_links() does not align with the operational requirements of drivers that groups multiple hardware under a single wiphy. These drivers (e.g ath12k) rely on channel assignment to determine the appropriate hardware for each link. Without this, the drivers cannot correctly establish the link interface. Currently in _ieee80211_set_active_links(), after calling drv_change_vif_links() on the driver, the state of all connected stations is updated via drv_change_sta_links(). This is followed by handling keys in the links, and finally, assigning the channel to the links. Consequently, drv_change_sta_links() prompts drivers to create the station entry at their level and within their firmware. However, since channels have not yet been assigned to links at this stage, drivers have not created the necessary link interface for establishing link stations, leading to failures in activating the links. Therefore, re-order the logic so that after drv_change_vif_links() and removing the old links, channels are assigned to newly added links. Following this, the flow proceeds to station handling.

2024-09-27[tree-wide] finally take no_llseek outAl Viro
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

2024-09-03wifi: iwlwifi: mvm: properly set the rates in link cmdMiri Korenblit
When a channel ctx is assigned to a link, we set the LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now valid. But then we always take the rates of 2.4 GHz regardless of actual used band. This is because we are getting the band from bss_conf->chanctx_conf, but this is assigned only after drv_assign_vif_chanctx returns, so we take the bands of 2.4 GHz. Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead, as this has already assigned in this point.

2024-09-03wifi: iwlwifi: mvm: tell the firmware about CSA with mode=1Emmanuel Grumbach
When we de-activate a link because it started a CSA with mode=1, we want to tell the firmware it can no longer transmit any frame for that link. The firmware will do that on its own if the CSA indication (beacon / action frame) was received on that same link, but with MLO, things got more complex and the firmware can't track cross link CSA. Tell the firmware if we de-activate a link because of CSA with mode=1 to prevent it from transmitting, even if it is only an NDP PM=1 frame that is part of the de-activation flow.
