wifi: cfg80211: do some rework towards MLO link APIs

2022-06-20T10:54:58+00:00

In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.

wifi: wilc1000: add IGTK support

2022-05-30T11:18:00+00:00

Add support to handle IGTK keys which are required for MFP to FW. Index ID 4 and 5 are used to store the IGTK key. Signed-off-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220524120606.9675-4-ajay.kathat@microchip.com

wifi: wilc1000: add WPA3 SAE support

2022-05-30T11:18:00+00:00

Enable SAE authentication for AP and STA mode. In STA mode, allow the driver to pass the auth frames which are received from firmware to userspace application(hostapd) so that SAE authentication is offloaded to userspace.

wifi: wilc1000: remove WEP security support

2022-05-30T11:18:00+00:00

Deprecated WEP security for WILC driver as well as in firmware from 15.6 FW release onwards. After WEP security removal, freeup some codespace which helped to add new features like WPA3 etc. Signed-off-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220524120606.9675-2-ajay.kathat@microchip.com

wifi: wilc1000: use correct sequence of RESET for chip Power-UP/Down

2022-05-30T11:18:00+00:00

For power-up sequence, WILC expects RESET set to high 5ms after making chip_en(enable) so corrected chip power-up sequence by making RESET high. For Power-Down sequence, the correct sequence make RESET and CHIP_EN low without any extra delay.

wilc1000: add valid vmm_entry check before fetching from TX queue

2022-05-11T05:25:34+00:00

'vmm_table' array contains the size of data buffer length including host header length. In 'vmm_table' array, the Zero value means the end of vmm_entries that needs to transfer to firmware which is calculated based on VMM free size in firmware. Use 'vmm_table' valid entry check before fetching the entry from TX queue to only copy valid number of entries to avoid possible NULL pointer exception observed sometimes during large file transfers.

wilc1000: fix crash observed in AP mode with cfg80211_register_netdevice()

2022-05-11T05:25:33+00:00

Monitor(mon.) interface is used for handling the AP mode and 'ieee80211_ptr' reference is not getting set for it. Like earlier implementation, use register_netdevice() instead of cfg80211_register_netdevice() which expects valid 'ieee80211_ptr' reference to avoid the possible crash.
