Emmanuel Grumbach cac9544cec wifi: iwlwifi: mvm: replace CONFIG_PM by CONFIG_PM_SLEEP
Replace the ifdef CONFIG_PM by CONFIG_PM_SLEEP. CONFIG_PM was useful
when we had CONFIG_PM_RUNTIME but that was removed long ago.
Use PM_SLEEP consistently across the driver.

Miri Korenblit a032b5fc24 wifi: iwlwifi: mvm: properly set the rates in link cmd
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.

Emmanuel Grumbach 07fb53783b wifi: iwlwifi: mvm: tell the firmware about CSA with mode=1
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.

Daniel Gabay b2a7c91bf9 wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmware
Currently, the driver handles SMPS decisions by tracking AP
capabilities, BT coexistence changes, sending necessary SMPS
frames to the AP, and updating firmware with RX chain info
using the RLC_CONFIG_CMD.

Starting with version 3 of the RLC_CONFIG_CMD, the firmware
takes over this responsibility. It now tracks SMPS, sends
frames, and configures the RLC.

In this patch:
1. Stop sending RLC_CONFIG_CMD when firmware supports RLC
   offload (version 3), as rlc.rx_chain_info is not needed by
   firmware, and no other field in the cmd is used.
2. Prevent the driver from forwarding any SMPS requests to
   mac80211, i.e., the driver should not transmit SMPS frames
   to the AP as firmware handles that.
3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS
   conditionally based on RLC version.

The entries[] array needs to be cacheline aligned to avoid false
sharing between different queues, each queue has a set of entries
in it that it writes to.

While it is aligned in practice today given that each array entry
before it is aligned, it's still clearer to explicitly require it
to be aligned, so add the annotation for that.

Johannes Berg 8c62617295 wifi: mac80211: remove DEAUTH_NEED_MGD_TX_PREP
This flag is annoying because it puts a lot of logic into mac80211
that could just as well be in the driver (only iwlmvm uses it) and
the implementation is also broken for MLO.

Remove the flag in favour of calling drv_mgd_prepare_tx() without
any conditions even for the deauth-while-assoc case. The drivers
that implement it can take the appropriate actions, which for the
only user of DEAUTH_NEED_MGD_TX_PREP (iwlmvm) is a bit more tricky
than the implementation in mac80211 is anyway, and all others have
no need and can just exit if info->was_assoc is set.

Johannes Berg 67c638675d wifi: iwlwifi: mvm: rename 'pldr_sync'
PLDR (product level device reset) is a Windows term, and
is something the driver triggers there, AFAICT.

Really what 'pldr_sync' here wants to capture is whether
or not the firmware will/may do a product reset during
initialization, which makes the device drop off the bus,
requiring a rescan. If this is the case, obviously the
init will fail/time out, so we don't want to report all
kinds of errors etc., hence this tracking variable.

Rename it to 'fw_product_reset' to capture the meaning

Ilan Peer 2e194efa38 wifi: iwlwifi: mvm: Fix race in scan completion
The move of the scan complete notification handling to the wiphy worker
introduced a race between scan complete notification and scan abort:

- The wiphy lock is held, e.g., for rfkill handling etc.
- Scan complete notification is received but not handled yet.
- Scan abort is triggered, and scan abort is sent to the FW. Once the
  scan abort command is sent successfully, the flow synchronously waits
  for the scan complete notification. However, as the scan complete
  notification was already received but not processed yet, this hangs for
  a second and continues leaving the scan status in an inconsistent
  state.
- Once scan complete handling is started (when the wiphy lock is not held)
  since the scan status is not an inconsistent state, a warning is issued
  and the scan complete notification is not handled.

To fix this issue, switch back the scan complete notification to be
asynchronously handling, and only move the link selection logic to
a worker (which was the original reason for the move to use wiphy lock).

While at it, refactor some prints to improve debug data.

Yedidya Benshimol a1efeb8230 wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is active
When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR

Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.

Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.

Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.

Miri Korenblit 72c19df24a wifi: iwlwifi: cleanup EMLSR when BT is active handling
BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it

checking if EMLSR is blocked or not for a specific vif.

Therefore, change the BT Coex bit to be an exit reason and not a

GHz link instead of checking that bit.
