2023-10-23wifi: iwlwifi: mvm: Don't always bind/link the P2P Device interfaceIlan Peer6-189/+111
It is not necessary to keep the P2P Device bound/linked to a PHY context when there is no active ROC. Modify the P2P Device flows so the binding/linking would be done only while ROC is active. With this change the switch_phy_ctxt() is no longer needed so remove it.

2023-10-23wifi: iwlwifi: mvm: add start mac ctdp sum calculation debugfs handleriallouch1-1/+43
mac_ctdp_sum contains the power consumption, appears in power save report, and is used for debugging and collection of statistics. Add a debugfs handler to start this calculation, iff ctdp command is supported in the firmware. While on it, add an option to force start/stop this calculation, which is safe from the firmware API side.

2023-10-23wifi: iwlwifi: abort scan when rfkill on but device enabledMiri Korenblit1-1/+1
In RFKILL we first set the RFKILL bit, then we abort scan (if one exists) by waiting for the notification from FW and notifying mac80211. And then we stop the device. But in case we have a scan ongoing in the period of time between rfkill on and before the device is stopped - we will not wait for the FW notification because of the iwl_mvm_is_radio_killed() condition, and then the scan_status and uid_status are misconfigured, (scan_status is cleared but uid_status not) and when the notification suddenly arrives (before stopping the device) we will get into the assert about scan_status and uid_status mismatch. Fix this by waiting for FW notif when rfkill is on but the device isn't disabled yet.

2023-10-23wifi: iwlwifi: mvm: Add basic link selection logicIlan Peer4-0/+133
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 Korenblit4-0/+52
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).

There's a race when the device is unbound (maybe because the module is unloaded) while the opmode start hasn't finished yet. The complete(request_firmware_complete) after the opmode start was meant (and commented accordingly) to prevent this problem, but it's not sufficient when the opmode module is loaded after the firmware load already completed, which happens regularly now because firmware load doesn't require userspace, unlike module load.

There's a race with runtime PM getting enabled by userspace: - we rescan the PCI bus - this creates the new PCI device including its sysfs representation - udev sees the new device, and the (OS-specific?) scripting enables runtime PM by writing to power/control; this can happen _before_ the next step - this will runtime-suspend the device which saves the config space, including the BAR0 that wasn't assigned yet - the bus rescan assigns resources to the devices and writes them to the config space of the device (but not the runtime-pm saved copy) - the driver binds and this disallows runtime PM, so the device is resumed, restoring the (incomplete!) config space - the driver cannot work due to BAR0 not being configured Fixing the actual race is hard and deep in the PCI layer, though probably should be done for upstream as well; perhaps runtime PM should only be allowed after resource assignment, or some other TBD way. Work around this in the driver for now by simply (re-)assigning BAR0 when the driver initializes, if it's unset.

2023-09-25wifi: iwlwifi: mvm: support set_antenna()Emmanuel Grumbach9-27/+148
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).

2023-09-21wifi: ipw2x00: Annotate struct libipw_txb with __counted_byKees Cook1-1/+1
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct libipw_txb.

Transition to d3 is much faster if there is no power save during the transition.

2023-09-13wifi: iwlwifi: mvm: fix recovery flow in CSAEmmanuel Grumbach1-1/+6
If the firmware crashes in the de-activation / re-activation of the link during CSA, we will not have a valid phy_ctxt pointer in mvmvif. This is a legit case, but when mac80211 removes the station to cleanup our state during the re-configuration, we need to make sure we clear ap_sta otherwise we won't re-add the station after the firmware has been restarted. Later on, we'd activate the link, try to send a TLC command crash again on ASSERT 3508. Fix this by properly cleaning up our state.

2023-09-13wifi: iwlwifi: Use FW rate for non-data framesMiri Korenblit1-5/+9
Currently we are setting the rate in the tx cmd for mgmt frames (e.g. during connection establishment). This was problematic when sending mgmt frames in eSR mode, as we don't know what link this frame will be sent on (This is decided by the FW), so we don't know what is the lowest rate. Fix this by not setting the rate in tx cmd and rely on FW to choose the right one. Set rate only for injected frames with fixed rate, or when no sta is given. Also set for important frames (EAPOL etc.) the High Priority flag.

2023-09-13wifi: iwlwifi: mvm: enable FILS DF Tx on non-PSC channelShaul Triebitz3-6/+22
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.

2023-09-13wifi: iwlwifi: mvm: make "pldr_sync" mode effectiveJohannes Berg3-17/+18
If the device initialized with ME active, this would indeed work, since the NVM information would be obtained from ME. However, in the much more likely case that ME isn't active and the firmware takes actions requiring the sync, this was not working correctly when the firmware is only run at init to obtain NVM data, since mac80211 isn't even initialized. Fix this by moving the 'pldr_sync' handling to a different place.
