wifi: cfg80211/mac80211: move puncturing into chandef

2024-02-08T14:00:39Z

Aloka originally suggested that puncturing should be part of the chandef, so that it's treated correctly. At the time, I disagreed and it ended up not part of the chandef, but I've now realized that this was wrong. Even for clients, the RX, and perhaps more importantly, CCA configuration needs to take puncturing into account. Move puncturing into the chandef, and adjust all the code accordingly. Also add a few tests for puncturing in chandef compatibility checking.

wifi: cfg80211: remove wdev mutex

2023-09-11T09:27:23Z

Since we're now protecting everything with the wiphy mutex (and were really using it for almost everything before), there's no longer any real reason to have a separate wdev mutex. It may feel better, but really has no value. Signed-off-by: Johannes Berg

wifi: cfg80211: include puncturing bitmap in channel switch events

wifi: cfg80211: Extend cfg80211_update_owe_info_event() for MLD AP

2023-02-14T11:00:25Z

Add support to offload OWE processing to user space for MLD AP when driver's SME in use. Add new parameters in struct cfg80211_update_owe_info to provide below information in cfg80211_update_owe_info_event() call: - MLO link ID of the AP, with which station requested (re)association. This is applicable for both MLO and non-MLO station connections when the AP affiliated with an MLD. - Station's MLD address if the connection is MLO capable.

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: Fix possible buffer overflow in qtnf_event_handle_external_auth

2021-04-22T14:40:12Z

Function qtnf_event_handle_external_auth calls memcpy without checking the length. A user could control that length and trigger a buffer overflow. Fix by checking the length is within the maximum allowed size. Signed-off-by: Lee Gibson Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20210419145842.345787-1-leegib@gmail.com

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: support WPA3 SAE in AP mode

Enable WPA3 SAE support in AP mode. Driver currently supports cards that offload SAE authentication to userspace. So allow userspace software to subscribe and to send AUTH frames. Besides, enable AP mode support in external_auth cfg80211 callback. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: cleanup alignment in firmware communication protocol

2020-02-12T16:16:46Z

Make sure that all elements in QLINK protocol message are aligned to 4 bytes. For this purpose add necessary amount of padding bytes to each message. Besides, add padding for non-aligned variable length fields, e.g. SSID, so that the first byte of the next variable length element is aligned. to 4 bytes. Finally, introduce TLV parsing helpers to reduce boilerplate TLV parsing code. Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo
