2022-05-11wfx: use container_of() to get vifJaehee Park
Currently, upon virtual interface creation, wfx_add_interface() stores a reference to the corresponding struct ieee80211_vif in private data, for later usage. This is not needed when using the container_of construct. This construct already has all the info it needs to retrieve the reference to the corresponding struct from the offset that is already available, inherent in container_of(), between its type and member inputs (struct ieee80211_vif and drv_priv, respectively). Remove vif (which was previously storing the reference to the struct ieee80211_vif) from the struct wfx_vif, define a function wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with the newly defined container_of construct.

'vmm_table' array contains the size of data buffer length including host header length.

2022-05-06wl1251: dynamically allocate memory used for DMAH. Nikolaus Schaller
With introduction of vmap'ed stacks, stack parameters can no longer be used for DMA and now leads to kernel panic. It happens at several places for the wl1251 (e.g. when accessed through SDIO) making it unuseable on e.g. the OpenPandora. We solve this by allocating temporary buffers or use wl1251_read32(). Tested on v5.18-rc5 with OpenPandora. Fixes: a1c510d0adc6 ("ARM: implement support for vmap'ed stacks") Signed-off-by: H.

In client mode, we can't connect to hidden SSID APs or SSIDs not advertised in beacons on DFS channels, since we're forced to passive scan. Fix this by sending out a probe request immediately after the first beacon, if active scan was requested by the user.

2022-05-04nl80211: rework internal_flags usageJohannes Berg
Since internal_flags is only 8 bits, we can only have one more internal flag. However, we can obviously never use all of possible the combinations, in fact, we only use 14 of them (including no flags). Since we want more flags for MLO (multi-link operation) in the future, refactor the code to use a flags selector, so wrap all of the .internal_flags assignments in a IFLAGS() macro which selects the combination according to the pre- defined list of combinations. When we need a new combination, we'll have to add it, but again we will never use all possible combinations.
