wifi: cfg80211: add locked debugfs wrappers

2023-11-27T10:24:58Z

Add wrappers for debugfs files that should be called with the wiphy mutex held, while the file is also to be removed under the wiphy mutex. This could otherwise deadlock when a file is trying to acquire the wiphy mutex while the code removing it holds the mutex but waits for the removal. This actually works by pushing the execution of the read or write handler to a wiphy work that can be cancelled using the debugfs cancellation API. Signed-off-by: Johannes Berg

wifi: cfg80211: hold wiphy mutex for send_interface

2023-11-24T17:30:48Z

Given all the locking rework in mac80211, we pretty much need to get into the driver with the wiphy mutex held in all callbacks. This is already mostly the case, but as Johan reported, in the get_txpower it may not be true. Lock the wiphy mutex around nl80211_send_iface(), then is also around callers of nl80211_notify_iface(). This is easy to do, fixes the problem, and aligns the locking between various calls to it in different parts of the code of cfg80211.

wifi: cfg80211: fix CQM for non-range use

2023-11-24T17:29:35Z

My prior race fix here broke CQM when ranges aren't used, as the reporting worker now requires the cqm_config to be set in the wdev, but isn't set when there's no range configured. Rather than continuing to special-case the range version, set the cqm_config always and configure accordingly, also tracking if range was used or not to be able to clear the configuration appropriately with the same API, which was actually not right if both were implemented by a driver for some reason, as is the case with mac80211 (though there the implementations are equivalent so it doesn't matter.) Also, the original multiple-RSSI commit lost checking for the callback, so might have potentially crashed if a driver had neither implementation, and userspace tried to use it despite not being advertised as supported.

netlink: make range pointers in policies const

2023-10-26T23:24:09Z

struct nla_policy is usually constant itself, but unless we make the ranges inside constant we won't be able to make range structs const. The ranges are not modified by the core.

wifi: cfg80211: fix assoc response warning on failed links

2023-10-23T11:25:30Z

The warning here shouldn't be done before we even set the bss field (or should've used the input data). Move the assignment before the warning to fix it. We noticed this now because of Wen's bugfix, where the bug fixed there had previously hidden this other bug.

wifi: cfg80211: Allow AP/P2PGO to indicate port authorization to peer STA/P2PClient

2023-10-23T10:50:44Z

In 4way handshake offload, cfg80211_port_authorized enables driver to indicate successful 4way handshake to cfg80211 layer. Currently this path of port authorization is restricted to interface type NL80211_IFTYPE_STATION and NL80211_IFTYPE_P2P_CLIENT. This patch extends the support for NL80211_IFTYPE_AP and NL80211_IFTYPE_P2P_GO interfaces to authorize peer STA/P2P_CLIENT, whenever authentication is offloaded on the AP/P2P_GO interface.
