Add puncturing bitmap in channel switch notifications and corresponding trace functions. Signed-off-by:

Aloka Dixit authored
- New feature flag, NL80211_EXT_FEATURE_PUNCT, to advertise driver support for preamble puncturing in AP mode. - New attribute, NL80211_ATTR_PUNCT_BITMAP, to receive a puncturing bitmap from the userspace during AP bring up (NL80211_CMD_START_AP) and channel switch (NL80211_CMD_CHANNEL_SWITCH) operations. Each bit corresponds to a 20 MHz channel in the operating bandwidth, lowest bit for the lowest channel. Bit set to 1 indicates that the channel is punctured. Higher 16 bits are reserved. - New members added to structures cfg80211_ap_settings and cfg80211_csa_settings to propagate the bitmap to the driver after validation. Signed-off-by:

- Move ieee80211_valid_disable_subchannel_bitmap() from mlme.c to chan.c, rename it as cfg80211_valid_disable_subchannel_bitmap() and export it. - Modify the prototype to include struct cfg80211_chan_def instead of only bandwidth to support a check which returns false if the primary channel is punctured.

It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming that hold port identifiers portid instead of pid. This change replicates following commit: commit 15e47304 ("netlink: Rename pid to portid to avoid confusion") Signed-off-by:

Userspace processes such as network daemons may wish to be informed when any AP interface is brought up on the system, for example to initiate a (re)configuration of IP settings or to start a DHCP server. Currently nl80211 does not broadcast any such event on its multicast groups, leaving userspace only two options: 1. the process must be the one that actually issued the NL80211_CMD_START_AP request, so that it can react on the response to that request; 2. the process must react to RTM_NEWLINK events indicating a change in carrier state, and may query for further information about the AP and react accordingly. Option (1) is robust, but it does not cover all scenarios. It is easy to imagine a situation where this is not the case (e.g. hostapd + systemd-networkd). Option (2) is not robust, because RTM_NEWLINK events may be silently discarded by the linkwatch logic (cf. linkwatch_fire_event()). Concretely, consider a scenario in which the carrier state flip-flops in the following way: ^ carrier state (high/low = carrier/no carrier) | | _______ _______ ... | | | | | ______| "foo" |____| "bar" (SSID in "quotes") | +-------A-------B----C---------> time If the time interval between (A) and (C) is less than 1 second, then linkwatch may emit only a single RTM_NEWLINK event indicating carrier gain. This is problematic because it is possible that the network configuration that should be applied is a function of the AP's properties such as SSID (cf. SSID= in systemd.network(5)). As illustrated in the above diagram, it may be that the AP with SSID "bar" ends up being configured as though it had SSID "foo". Address the above issue by having nl80211 emit an NL80211_CMD_START_AP message on the MLME nl80211 multicast group. This allows for arbitrary processes to be reliably informed. Signed-off-by:

Add support to offload OWE processing to user space for MLD AP when driver's SME in use. Add new parameters in struct cfg80211_update_owe_info to provide below information in cfg80211_update_owe_info_event() call: - MLO link ID of the AP, with which station requested (re)association. This is applicable for both MLO and non-MLO station connections when the AP affiliated with an MLD. - Station's MLD address if the connection is MLO capable. Signed-off-by:

Key information in wext.connect is not reset on (re)connect and can hold data from a previous connection.

Currently authentication request event interface doesn't have support to indicate the user space whether it should enable MLO or not during the authentication with the specified AP. But driver needs such capability since the connection is MLO or not decided by the driver in case of SME offload to the driver. Add support for driver to indicate MLD address of the AP in authentication offload request to inform user space to enable MLO during authentication process. Driver shall look at NL80211_ATTR_MLO_SUPPORT flag capability in NL80211_CMD_CONNECT to know whether the user space supports enabling MLO during the authentication offload. User space should enable MLO during the authentication only when it receives the AP MLD address in authentication offload request. User space shouldn't enable MLO if the authentication offload request doesn't indicate the AP MLD address even if the AP is MLO capable. When MLO is enabled, user space should use the MAC address of the interface (on which driver sent request) as self MLD address. User space and driver to use MLD addresses in RA, TA and BSSID fields of the frames between them, and driver translates the MLD addresses to/from link addresses based on the link chosen for the authentication.

If the chip can have an LED, register a struct led_classdev and enable hardware-controlled blinking. When the chip is not transmitting or receiving anything the LED is off. Otherwise the LED will blink faster or slower according to the throughput. The LED can be controlled from userspace by writing 0, 1, or 2 to /sys/class/leds/rtl8xxxu-usbX-Y/brightness: 0 - solid off. 1 - solid on. 2 - hardware-controlled blinking. In this patch none of the chips advertise having an LED. That will be added in the next patches. Signed-off-by:

For a packet with 1SS rate, it can also transmit via 2 antenna, called 2T mode. For 2T TX power offset, mask should be 2T as well. Fortunately, the mask of 2T and 1T are the same, so it can still work well without this fix. Signed-off-by:

In path of setting channel and setting TX power, the rtw89_chan instance to be used is controlled by top and passed down. The set_tx_shape_dfir() is in path of setting TX power, so it should use the passed rtw89_chan instead of querying it itself. Otherwise, it might encounter mismatch between parameters if multi-channel. For example, rtw89_8852ce 0000:04:00.0: set tx shape dfir by unknown ch: 155 on 2GHz Signed-off-by:

Driver can prepare pkt_list for firmware that only uses them to send out the packets in specific situations. To understand the usage of current status, and to check if there is leakage problem, dump bitmap and the indices used by certain function.

RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB. It will feedback an error when host does an invalid BUS operation. For example, * BUS master request without power/clock on. * host reads/writes/accesses an invalid address. They might lead to problems such as BUS timeout, platform hang, etc. So, once if RXI300 feedback an error, it notifies that driver need a L2 SER (system error recovery) to reset things. Previously, driver did not parse the error scenario for RXI300. We add it and assign a corresponding error code which will make SER flow do L2 reset. Signed-off-by:

Originally, rtw89_mac_port_tsf_sync() contains randomization logic internally. However, not all situation, we need the randomization. So, split out the generic part from it. And, make the full logic of original one contained in rtw89_mac_port_tsf_sync_rand(). It will still be used by its original caller as before. Then, the generic one will be used in MCC (multi-channel concurrency) management flow. MCC will implement its logic to decide the offset for TSF sync. Signed-off-by:
