2023-09-25wifi: cfg80211: split struct cfg80211_ap_settingsJohannes Berg
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 <johannes.berg@intel.com>

2022-10-11treewide: use get_random_u32() when possibleJason A. Donenfeld
The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-06-20wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg
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.

2021-01-22cfg80211: change netdev registration/unregistration semanticsJohannes Berg
We used to not require anything in terms of registering netdevs with cfg80211, using a netdev notifier instead. However, in the next patch reducing RTNL locking, this causes big problems, and the simplest way is to just require drivers to do things better. Change the registration/unregistration semantics to require the drivers to call cfg80211_(un)register_netdevice() when this is happening due to a cfg80211 request, i.e. add_virtual_intf() or del_virtual_intf() (or if it somehow has to happen in any other cfg80211 callback). Otherwise, in other contexts, drivers may continue to use the normal netdev (un)registration functions as usual. Internally, we still use the netdev notifier and track (by the new wdev->registered bool) if the wdev had already been added to cfg80211 or not. Link: https://lore.kernel.org/r/20210122161942.cf2f4b65e4e9.Ida8234e50da13eb675b557bac52a713ad4eddf71@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2020-04-24cfg80211: change internal management frame registration APIJohannes Berg
Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.

2020-03-12qtnfmac: assign each wiphy to its own virtual platform deviceSergey Matyukevich
Quantenna Pearl device exposes multiple (up to 3) radio interfaces under single PCIe function. So far all the wiphy devices were attached to the same pcie device. As a result, all different wireless network devices were reported under the same sysfs directory for pcie device, e.g.: $ ls /sys/class/net/wlan0/device/net/ wlan0 wlan1 It turns out that such behavior may confuse various users of wireless subsystem. For instance, it turned out to be the case for: - Linux init systems, e.g. for renaming based on parent device - OpenWRT configuration scripts Suggested solution is to add an intermediate virtual platform device for each radio interface.

2019-11-20qtnfmac: track broadcast domain of each interfaceIgor Mitsyanko
If firmware reports that it supports hardware switch capabilities, driver needs to track and notify device whenever broadcast domain of a particular network device changes (ie. whenever it's upper master device changes). Firmware needs a unique ID to tell broadcast domains from each other which is an opaque number otherwise. For that purpose we can use netspace:ifidx pair to uniquely identify each broadcast domain: - if netdev is not part of a bridge, then use it's own ifidx as a broadcast domain ID - if netdev is part of a bridge, then use bridge netdev ifidx as broadcast domain ID Firmware makes sure that packets are only forwarded between interfaces marked with the same broadcast domain ID.

2019-02-08qtnfmac: enable WPA3 SAE supportSergey Matyukevich
In the case of SAE AP, drivers offload authentication to user-space software, e.g. hostapd. For FullMAC drivers the procedure is as follows. If auth_type is SAE and user space indicates external authentication capability, then driver requests authentication offload to user-space software using cfg80211_external_auth_request call. From that point, auth frame exchange is performed transparently for driver: user-space software sends/receives mgmt frames using mgmt_tx/mgmt_frame_register cfg80211 callbacks. As soon as authenitcation is completed, user-space software notifies driver about its status using external_auth cfg80211 callback.

2018-05-30qtnfmac: fix invalid STA state on EAPOL failureSergey Matyukevich
Driver switches vif sta_state into QTNF_STA_CONNECTING when cfg80211 core initiates connect procedure. Further this state is changed either to QTNF_STA_CONNECTED or to QTNF_STA_DISCONNECTED by BSS_JOIN and BSS_LEAVE events from firmware. However it is possible that no such events will be sent by firmware, e.g. if EAPOL timed out. In this case vif sta_mode will remain in QTNF_STA_CONNECTING state and all subsequent connection attempts will fail with -EBUSY error code. Fix this by perfroming STA state transition from QTNF_STA_CONNECTING to QTNF_STA_DISCONNECTED in cfg80211 disconnect callback. No need to rely upon firmware events in this case.
