Add support to set SA/DA/BSSID in testmode. During mass production stage, some test scripts or test equipments need to set fixed addresses to detect or parse if a test is passed. Also, MAC setting is necessary for some tx/rx tests with rx filter, to make sure rx site only receives expected packets.

2021-12-16wcn36xx: Implement beacon filteringBryan O'Donoghue
The prima driver facilitates the direct programming of beacon filter tables via SMD commands. The purpose of beacon filters is quote: /* When beacon filtering is enabled, firmware will * analyze the selected beacons received during BMPS, * and monitor any changes in the IEs as listed below. * The format of the table is: * - EID * - Check for IE presence * - Byte offset * - Byte value * - Bit Mask * - Byte reference */ The default filter table looks something like this: tBeaconFilterIe gaBcnFilterTable[12] = { { WLAN_EID_DS_PARAMS, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_ERP_INFO, 0u, { 0u, 0u, 248u, 0u } }, { WLAN_EID_EDCA_PARAM_SET, 0u, { 0u, 0u, 240u, 0u } }, { WLAN_EID_QOS_CAPA, 0u, { 0u, 0u, 240u, 0u } }, { WLAN_EID_CHANNEL_SWITCH, 1u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_QUIET, 1u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 1u, 0u, 248u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 2u, 0u, 235u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 5u, 0u, 253u, 0u } }, { WLAN_EID_PWR_CONSTRAINT, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_OPMODE_NOTIF, 0u, { 0u, 0u, 0u, 0u } } }; Add in an equivalent filter set as present in the prima Linux driver. For now omit the beacon filter "rem" command as the driver does not have an explicit call to that SMD command. The filter mask should only count when we are inside BMPS anyway. Replicating the ability to program the filter table gives us scope to add and remove elements in future. For now though this patch makes the rote-copy of the downstream Linux beacon filter table, which we can tweak as desired from now on.

2021-12-16wilc1000: Improve WILC TX performance when power_save is offDavid Mosberger-Tang
The wakeup and sleep commands need to be sent to the WILC chip only when it is in power save mode (PSM, as controlled by "iw dev wlan0 set power_save on/off"). The commands are relatively costly, so it pays to skip them when possible. iperf3 without this patch (no significant different with PSM on/off): TX 0.00-120.01 sec 140 MBytes 9.82 Mbits/sec RX 0.00-120.69 sec 283 MBytes 19.6 Mbits/sec with this patch applied: PSM off (TX is 46% improved, RX slightly improved; may not be significant): TX 0.00-120.00 sec 206 MBytes 14.4 Mbits/sec RX 0.00-120.48 sec 322 MBytes 22.4 Mbits/sec PSM on (no significant change): TX 0.00-120.00 sec 140 MBytes 9.78 Mbits/sec RX 0.00-120.08 sec 257 MBytes 18.0 Mbits/sec Signed-off-by: David Mosberger-Tang <davidm@egauge.net> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20211210203016.3680425-2-davidm@egauge.net

This fix is similar to commit 77c91295ea53 ("wil6210: specify max. IE length"). Without the max IE length set, wpa_supplicant cannot operate using the nl80211 interface. This patch is a workaround - the number 512 is taken from the wlcore driver, but note that per Paul Fertser: there's no correct number because the driver will ignore the data passed in extra IEs.

2021-12-14wilc1000: Rename workqueue from "WILC_wq" to "NETDEV-wq"David Mosberger-Tang
This follows normal Linux convention and is more useful since the new name will make it apparent which network device the work-queue is for (e.g., the name will be "wlan0-wq" for network device "wlan0"). hif_workqueue allocation has to move from cfg80211.c:wilc_cfg80211_init() to netdev.c:wilc_netdev_ifc_init() because the network device name is not known until after the netdev is registered. The move also makes sense because netdev.c is already responsible for destroying the work queue when it is no longer needed.

2021-12-14wilc1000: Fix spurious "FW not responding" errorDavid Mosberger-Tang
When deinitializing the driver, one or more "FW not responding" error appears on the console. This appears to be due to wilc_wlan_stop() disabling host/WILC1000 communication, but then right afterwards, it tries to release the bus with chip-sleep enabled. The problem is enabling the chip-sleep cannot success once host/WILC1000 communication is disabled. Fix by only releasing the bus.

2021-12-14wilc1000: Remove misleading USE_SPI_DMA macroDavid Mosberger-Tang
The USE_SPI_DMA macro name suggests that it could be set to 1 to control whether or not SPI DMA should be used. However, that's not what it does. If set to 1, it'll set the SPI messages' "is_dma_mapped" flag to true, even though the tx/rx buffers aren't actually DMA mapped by the driver. In other words, setting this flag to 1 will break the driver. Best to clean up this confusion by removing the macro altogether. There is no need to explicitly initialize "is_dma_mapped" because the message is cleared to zero anyhow, so "is_dma_mapped" is set to false by default.

2021-12-14ath11k: Fix a NULL pointer dereference in ath11k_mac_op_hw_scan()Zhou Qingyang
In ath11k_mac_op_hw_scan(), the return value of kzalloc() is directly used in memcpy(), which may lead to a NULL pointer dereference on failure of kzalloc(). Fix this bug by adding a check of arg.extraie.ptr. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_ATH11K=m show no new warnings, and our static analyzer no longer warns about this code.

Update complete_and_exit to call kthread_exit instead of do_exit. Change the name to reflect this change in functionality. All of the users of complete_and_exit are causing the current kthread to exit so this change makes it clear what is happening. Move the implementation of kthread_complete_and_exit from kernel/exit.c to to kernel/kthread.c. As this function is kthread specific it makes most sense to live with the kthread functions.

As a result lockdep suspects that the task is trying to acquire the same lock (due to same key) while already holding it, and thus reports the DEADLOCK warning. However as they are different spinlock instances, the warning is false positive. On the other hand, even no dead lock indeed, this is a major issue for upstream regression testing as it disables lockdep functionality. Fix it by assigning separate lock class key for each srng->lock.
