wifi: fill in MODULE_DESCRIPTION()s for wilc1000

2024-01-31T16:32:33Z

W=1 builds now warn if module is built without a MODULE_DESCRIPTION(). Add descriptions to the Atmel WILC1000 SPI driver. Signed-off-by: Breno Leitao Signed-off-by: Kalle Valo Link: https://msgid.link/20240130104243.3025393-9-leitao@debian.org

wifi: wilc1000: simplify wilc_scan()

2023-11-08T18:07:55Z

Simplify 'wilc_scan()' assuming 'struct wilc_priv *' is the only data passed to '(*scan_result)()' callback and thus avoid typeless 'void *' pointers in related code, including 'struct wilc_user_scan_req'. Compile tested only. Signed-off-by: Dmitry Antipov Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20231031171330.70399-2-dmantipov@yandex.ru

wifi: wilc1000: cleanup struct wilc_conn_info

2023-11-08T18:07:55Z

Remove set but otherwise unused 'ch' member of 'struct wilc_conn_info' and avoid typeless 'void *' pointers in '(*conn_result)()' callback. Likewise for 'wilc_parse_join_bss_param()'.

wifi: wilc1000: always release SDIO host in wilc_sdio_cmd53()

2023-10-30T17:23:51Z

Ensure 'sdio_release_host()' is always issued on return from 'wilc_sdio_cmd53()'. Compile tested only. Signed-off-by: Dmitry Antipov Acked-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20231026141016.71407-2-dmantipov@yandex.ru

wifi: wilc1000: simplify remain on channel support

2023-10-30T17:23:51Z

For 'struct wilc_remain_ch', drop set but otherwise unused 'duration' field and adjust 'expired' callback assuming that the only data passed to it is 'struct wilc_vif *', thus making 'wilc_remain_on_channel()' a bit simpler as well.

wifi: wilc1000: use vmm_table as array in wilc struct

2023-10-19T07:30:34Z

Enabling KASAN and running some iperf tests raises some memory issues with vmm_table: BUG: KASAN: slab-out-of-bounds in wilc_wlan_handle_txq+0x6ac/0xdb4 Write of size 4 at addr c3a61540 by task wlan0-tx/95 KASAN detects that we are writing data beyond range allocated to vmm_table. There is indeed a mismatch between the size passed to allocator in wilc_wlan_init, and the range of possible indexes used later: allocation size is missing a multiplication by sizeof(u32) Fixes: 40b717bfcefa ("wifi: wilc1000: fix DMA on stack objects") Cc: stable@vger.kernel.org Signed-off-by: Ajay Singh Signed-off-by: Alexis Lothoré Reviewed-by: Michael Walle Reviewed-by: Jeff Johnson Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20231017-wilc1000_tx_oops-v3-1-b2155f1f7bee@bootlin.com

wifi: cfg80211: split struct cfg80211_ap_settings

2023-09-25T07:00:39Z

Using the full struct cfg80211_ap_settings for an update is misleading, since most settings cannot be updated. Split the update case off into a new struct cfg80211_ap_update. Change-Id: I3ba4dd9280938ab41252f145227a7005edf327e4 Signed-off-by: Johannes Berg

wifi: wilc1000: add back-off algorithm to balance tx queue packets

2023-09-21T06:30:11Z

Add an algorithm to backoff the Tx Task when low memory scenario is triggered at firmware. During high data transfer from host, the firmware runs out of VMM memory, which is used to hold the frames from the host. So, adding the flow control delays the transmit from host side when there is not enough space to accommodate frames in firmware side.

wifi: cfg80211: modify prototype for change_beacon

2023-09-13T10:34:01Z

Modify the prototype for change_beacon() in struct cfg80211_op to accept cfg80211_ap_settings instead of cfg80211_beacon_data so that it can process data in addition to beacons. Modify the prototypes of ieee80211_change_beacon() and driver specific functions accordingly.

Commit 8399918f3056 ("staging: wilc1000: use RCU list to maintain vif interfaces list") removed wilc_get_interface() but not its declaration. Commit 9bc061e88054 ("staging: wilc1000: added support to dynamically add/remove interfaces") declared but never implemented wilc_cfg_alloc() and wilc_netdev_interface().
