wifi: cfg80211: annotate iftype_data pointer with sparse

2023-09-11T09:27:23Z

There were are a number of cases in mac80211 and iwlwifi (at least) that used the sband->iftype_data pointer directly, instead of using the accessors to find the right array entry to use. Make sparse warn when such a thing is done. To not have a lot of casts, add two helper functions/macros - ieee80211_set_sband_iftype_data() - for_each_sband_iftype_data() Signed-off-by: Johannes Berg

wifi: qtnfmac: use struct_size and size_sub for payload length

2023-03-13T13:44:29Z

Replace the calculations for the payload length in qtnf_cmd_band_fill_iftype with struct_size() and size_sub(). While the payload length does not get directly passed to an allocation function, the performed calculation is still calculating the size of a flexible array structure (minus the size of a header structure).

wifi: move from strlcpy with unused retval to strscpy

2022-09-02T08:47:22Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

wifi: cfg80211: Increase akm_suites array size in cfg80211_crypto_settings

2022-07-01T10:07:08Z

Increase akm_suites array size in struct cfg80211_crypto_settings to 10 and advertise the capability to userspace. This allows userspace to send more than two AKMs to driver in netlink commands such as NL80211_CMD_CONNECT. This capability is needed for implementing WPA3-Personal transition mode correctly with any driver that handles roaming internally. Currently, the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256, SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing the akm_suites array size to 10 should be reasonable for future usecases.

wifi: cfg80211: do some rework towards MLO link APIs

2022-06-20T10:54:58Z

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.

qtnfmac: remove meaningless goto statement and labels

qtnfmac: fix resource leaks on unsupported iftype error return path

Currently if an unsupported iftype is detected the error return path does not free the cmd_skb leading to a resource leak. Fix this by free'ing cmd_skb.

qtnfmac: support WPA3 OWE in AP mode

2020-03-12T13:38:56Z

Enable WPA3 OWE support in AP mode. Driver currently supports cards that offload OWE processing to userspace. This patch adds all the required tools for such offloading. Firmware requests OWE processing sending new UPDATE_OWE event to driver, which uses cfg80211_update_owe_info_event to notify userspace software. After OWE processing is completed, userspace sends calculated IEs to firmware using update_owe_info cfg80211 callback. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: drop unnecessary TLVs from scan command

2020-02-12T16:16:48Z

Most part of scan command data is always present, so no need to keep it in TLV. Simplify scan command processing moving most part of its parameters into a fixed part of qlink_cmd_scan message. Use fixed dwell time values for normal scan when device is not connected, and allow wireless card decide on dwell times by itself if it's operating as a STA and is connected. When connected, card can select dwell times dynamically based on traffic conditions to get best results. Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo
