The FW does not allocate quota air time for the binding of a station MAC before iwlmvm indicates that it is associated. Currently iwlmvm indicates that the MAC is associated only after hearing a beacon from the AP. In case a deauthentication frame is sent before the MAC is associated, the frame might not be sent as the corresponding binding is not scheduled. To handle such cases, set IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP in the HW flags, requesting mac80211 to call the mgd_prepare_tx() callback before transmitting a deauthentication frame if associated but no beacon was heard from the AP. In addition, do not warn in iwl_mvm_mac_mgd_prepare_tx() when already associated as now the callback can be called also when associated. Signed-off-by:

Sometimes iwl_mvm_disable_txq() may be called with mac80211_queue == IEEE80211_INVAL_HW_QUEUE, and this would cause us to use BIT(0xFF) which is way too large for the u16 we used to store it in hw_queue_to_mac820211. If this happens the following UBSAN warning will be generated: [ 167.185167] UBSAN: Undefined behaviour in drivers/net/wireless/intel/iwlwifi/mvm/utils.c:838:5 [ 167.185171] shift exponent 255 is too large for 64-bit type 'long unsigned int' Fix that by checking that it is not IEEE80211_INVAL_HW_QUEUE and, while at it, add a warning if the queue number is larger than IEEE80211_MAX_QUEUES.

The brcms_ucode_init_buf() duplicates the ucode chunks via kmemdup() with GFP_ATOMIC as a precondition of wl->lock acquired. This caused allocation failures sometimes as reported in the bugzilla below. When looking at the the real usage, one can find that it's called solely from brcms_request_fw(), and it's obviously outside the lock. Hence we can use GFP_KERNEL there safely for avoiding such allocation errors. Bugzilla: http://bugzilla.suse.com/show_bug.cgi?id=1085174Signed-off-by:

The function brcmf_fw_alloc_request() takes a list of required files and allocated the struct brcmf_fw_request instance accordingly. The request can be modified by the caller before being passed to the brcmf_fw_request_firmwares() function. Reviewed-by:

Rework the driver so the wiphy instance holds the main driver information in its private buffer. Previously it held struct brcmf_cfg80211_info instance so a bit of reorg was needed. This was done so that the wiphy name or its parent device can be shown in debug output. Reviewed-by:

When logging the chip id/revision information make use of brcmf_chip_name() so it is always the same. Reviewed-by:
-
Arend Van Spriel authored
The chip id can either be four or five digits. For the chip name either the hexadecimal value needs to be taken (four digits) or the decimal value (five digits). The function brcmf_chip_name() does this conversion so use it to store the name in driver revision info. Reviewed-by:
