cfg80211: prevent speculation on cfg80211_classify8021d() return

2019-02-11T14:50:56Z

It's possible that the caller of cfg80211_classify8021d() uses the value to index an array, like mac80211 in ieee80211_downgrade_queue(). Prevent speculation on the return value. Signed-off-by: Johannes Berg Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

cfg80211: pmsr: record netlink port ID

2019-02-11T14:50:56Z

Without recording the netlink port ID, we cannot return the results or complete messages to userspace, nor will we be able to abort if the socket is closed, so clearly we need to fill the value. Signed-off-by: Johannes Berg Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

nl80211: Fix FTM per burst maximum value

2019-02-11T14:50:56Z

Fix FTM per burst maximum value from 15 to 31 (The maximal bits that represents that number in the frame is 5 hence a maximal value of 31) Signed-off-by: Aviya Erenfeld Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

cfg80211: pmsr: fix abort locking

2019-02-06T09:38:00Z

When we destroy the interface we already hold the wdev->mtx while calling cfg80211_pmsr_wdev_down(), which assumes this isn't true and flushes the worker that takes the lock, thus leading to a deadlock. Fix this by refactoring the worker and calling its code in cfg80211_pmsr_wdev_down() directly. We still need to flush the work later to make sure it's not still running and will crash, but it will not do anything.

cfg80211: pmsr: fix MAC address setting

2019-02-06T09:37:42Z

When we *don't* have a MAC address attribute, we shouldn't try to use this - this was intended to copy the local MAC address instead, so fix it. Fixes: 9bb7e0f24e7e ("cfg80211: add peer measurement with FTM initiator API") Signed-off-by: Johannes Berg

cfg80211: call disconnect_wk when AP stops

2019-02-01T10:12:50Z

Since we now prevent regulatory restore during STA disconnect if concurrent AP interfaces are active, we need to reschedule this check when the AP state changes. This fixes never doing a restore when an AP is the last interface to stop. Or to put it another way: we need to re-check after anything we check here changes.

cfg80211: extend range deviation for DMG

2019-01-25T09:18:51Z

Recently, DMG frequency bands have been extended till 71GHz, so extend the range check till 20GHz (45-71GHZ), else some channels will be marked as disabled. Signed-off-by: Chaitanya Tata Signed-off-by: Johannes Berg

cfg80211: reg: remove warn_on for a normal case

2019-01-25T09:18:02Z

If there are simulatenous queries of regdb, then there might be a case where multiple queries can trigger request_firmware_no_wait and can have parallel callbacks being executed asynchronously. In this scenario we might hit the WARN_ON. So remove the warn_on, as the code already handles multiple callbacks gracefully. Signed-off-by: Chaitanya Tata Signed-off-by: Johannes Berg

nl80211: fix NLA_POLICY_NESTED() arguments

2019-01-25T08:26:32Z

syzbot reported an out-of-bounds read when passing certain malformed messages into nl80211. The specific place where this happened isn't interesting, the problem is that nested policy parsing was referring to the wrong maximum attribute and thus the policy wasn't long enough. Fix this by referring to the correct attribute. Since this is really not necessary, I'll come up with a separate patch to just pass the policy instead of both, in the common case we can infer the maxattr from the size of the policy array.
