cfg80211: declare MODULE_FIRMWARE for regulatory.db

2022-06-09T08:26:26+00:00

commit 7bc7981eeebe1b8e603ad2ffc5e84f4df76920dd upstream.

Add MODULE_FIRMWARE declarations for regulatory.db and
regulatory.db.p7s such that userspace tooling can discover and include
these files.

nl80211: don't hold RTNL in color change request

2022-06-09T08:25:46+00:00

[ Upstream commit 1b550a0bebfc0b69d6ec08fe6eb58953a8aec48a ]

It's not necessary to hold the RTNL across color change
requests, since all the inner locking needs only the
wiphy mutex which we already hold as well.

nl80211: show SSID for P2P_GO interfaces

2022-06-09T08:25:39+00:00

[ Upstream commit a75971bc2b8453630e9f85e0beaa4da8db8277a3 ]

There's no real reason not to send the SSID to userspace
when it requests information about P2P_GO, it is, in that
respect, exactly the same as AP interfaces. Fix that.

nl80211: fix locking in nl80211_set_tx_bitrate_mask()

[ Upstream commit f971e1887fdb3ab500c9bebf4b98f62d49a20655 ]

This accesses the wdev's chandef etc., so cannot safely
be used without holding the lock.

cfg80211: retrieve S1G operating channel number

2022-05-25T07:59:13+00:00

[ Upstream commit e847ffe2d146cfd52980ca688d84358e024a6e70 ]

When retrieving the S1G channel number from IEs, we should retrieve
the operating channel instead of the primary channel. The S1G operation
element specifies the main channel of operation as the oper channel,
unlike for HT and HE which specify their main channel of operation as
the primary channel.

nl80211: correctly check NL80211_ATTR_REG_ALPHA2 size

2022-04-20T07:36:26+00:00

commit 6624bb34b4eb19f715db9908cca00122748765d7 upstream.

We need this to be at least two bytes, so we can access
alpha2[0] and alpha2[1]. It may be three in case some
userspace used NUL-termination since it was NLA_STRING
(and we also push it out with NUL-termination).

cfg80211: hold bss_lock while updating nontrans_list

2022-04-20T07:36:14+00:00

[ Upstream commit a5199b5626cd6913cf8776a835bc63d40e0686ad ]

Synchronize additions to nontrans_list of transmitting BSS with
bss_lock to avoid races. Also when cfg80211_add_nontrans_list() fails
__cfg80211_unlink_bss() needs bss_lock to be held (has lockdep assert
on bss_lock). So protect the whole block with bss_lock to avoid
races and warnings. Found during code review.

cfg80211: don't add non transmitted BSS to 6GHz scanned channels

2022-04-13T17:27:11+00:00

[ Upstream commit 5666ee154f4696c011dfa8544aaf5591b6b87515 ]

When adding 6GHz channels to scan request based on reported
co-located APs, don't add channels that have only APs with
"non-transmitted" BSSes if they only match the wildcard SSID since
they will be found by probing the "transmitted" BSS.

nl80211: Update bss channel on channel switch for P2P_CLIENT

2022-03-02T21:37:05+00:00

The wdev channel information is updated post channel switch only for
the station mode and not for the other modes. Due to this, the P2P client
still points to the old value though it moved to the new channel
when the channel change is induced from the P2P GO.

Update the bss channel after CSA channel switch completion for P2P client
interface as well.
