2020-02-14mac80211: allow setting queue_len for drivers not using wake_tx_queueJohn Crispin
Currently a mac80211 driver can only set the txq_limit when using wake_tx_queue. Not all drivers use wake_tx_queue. This patch adds a new element to wiphy allowing a driver to set a custom tx_queue_len and the code that will apply it in case it is set.

2020-02-14mac80211: Fix setting txpower to zeroBen Greear
With multiple VIFS ath10k, and probably others, tries to find the minimum txpower for all vifs and uses that when setting txpower in the firmware. If a second vif is added and starts to scan, it's txpower is not initialized yet and it set to zero. ath10k had a patch to ignore zero values, but then it is impossible to actually set txpower to zero. So, instead initialize the txpower to INT_MIN in mac80211, and let drivers know that means the power has not been set and so should be ignored.

2020-02-14mac80211: fix wrong 160/80+80 MHz settingShay Bar
Before this patch, STA's would set new width of 160/80+80 MHz based on AP capability only. This is wrong because STA may not support > 80MHz BW.

2020-02-07nl80211: add src and dst addr attributes for control port tx/rxMarkus Theil
When using control port over nl80211 in AP mode with pre-authentication, APs need to forward frames to other APs defined by their MAC address. Before this patch, pre-auth frames reaching user space over nl80211 control port have no longer any information about the dest attached, which can be used for forwarding to a controller or injecting the frame back to a ethernet interface over a AF_PACKET socket. Analog problems exist, when forwarding pre-auth frames from AP -> STA. This patch therefore adds the NL80211_ATTR_DST_MAC and NL80211_ATTR_SRC_MAC attributes to provide more context information when forwarding. The respective arguments are optional on tx and included on rx. Therefore unaware existing software is not affected. Software which wants to detect this feature, can do so by checking against: NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211_MAC_ADDRS Signed-off-by: Markus Theil <markus.theil@tu-ilmenau.de> Link: https://lore.kernel.org/r/20200115125522.3755-1-markus.theil@tu-ilmenau.de [split into separate cfg80211/mac80211 patches] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-02-07cfg80211/mac80211: Allow user space to register for station Rx authenticationIlan Peer
To support Pre Association Security Negotiation (PASN) while already associated to one AP, allow user space to register to Rx authentication frames, so that the user space logic would be able to receive/handle authentication frames from a different AP as part of PASN. Note that it is expected that user space would intelligently register for Rx authentication frames, i.e., only when PASN is used and configure a match filter only for PASN authentication algorithm, as otherwise the MLME functionality of mac80211 would be broken. Additionally, since some versions of the user space daemons wrongly register to all types of authentication frames (which might result in unexpected behavior) allow such registration if the request is for a specific authentication algorithm number.

2020-02-07mac80211: use more bits for ack_frame_idJohannes Berg
It turns out that this wasn't a good idea, I hit a test failure in hwsim due to this. That particular failure was easily worked around, but it raised questions: if an AP needs to, for example, send action frames to each connected station, the current limit is nowhere near enough (especially if those stations are sleeping and the frames are queued for a while.) Shuffle around some bits to make more room for ack_frame_id to allow up to 8192 queued up frames, that's enough for queueing 4 frames to each connected station, even at the maximum of 2007 stations on a single AP. We take the bits from band (which currently only 2 but I leave 3 in case we add another band) and from the hw_queue, which can only need 4 since it has a limit of 16 queues.

2020-01-15mac80211: add ieee80211_is_any_nullfunc()Thomas Pedersen
commit 08a5bdde3812 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED") Fixed a bug where we failed to take into account a nullfunc frame can be either non-QoS or QoS. It turns out there is at least one more bug in ieee80211_sta_tx_notify(), introduced in commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing"), where we forgot to check for the QoS variant and so assumed the QoS nullfunc frame never went out Fix this by adding a helper ieee80211_is_any_nullfunc() which consolidates the check for non-QoS and QoS nullfunc frames. Replace existing compound conditionals and add a couple more missing checks for QoS variant.

2020-01-15mac80211: add handling for BSS colorJohn Crispin
It is now possible to propagate BSS color settings into the subsystem. Lets make mac80211 also handle them so that we can send them further down the stack into the drivers. We drop the old bss_color field and change iwlwifi to use the new he_bss_color struct.

2020-01-15mac80211: Fix TKIP replay protection immediately after key setupJouni Malinen
TKIP replay protection was skipped for the very first frame received after a new key is configured. While this is potentially needed to avoid dropping a frame in some cases, this does leave a window for replay attacks with group-addressed frames at the station side. Any earlier frame sent by the AP using the same key would be accepted as a valid frame and the internal RSC would then be updated to the TSC from that frame. This would allow multiple previously transmitted group-addressed frames to be replayed until the next valid new group-addressed frame from the AP is received by the station. Fix this by limiting the no-replay-protection exception to apply only for the case where TSC=0, i.e., when this is for the very first frame protected using the new key, and the local RSC had not been set to a higher value when configuring the key (which may happen with GTK).

2020-01-15cfg80211: Fix radar event during another phy CACOrr Mazor
In case a radar event of CAC_FINISHED or RADAR_DETECTED happens during another phy is during CAC we might need to cancel that CAC. If we got a radar in a channel that another phy is now doing CAC on then the CAC should be canceled there. If, for example, 2 phys doing CAC on the same channels, or on comptable channels, once on of them will finish his CAC the other might need to cancel his CAC, since it is no longer relevant. To fix that the commit adds an callback and implement it in mac80211 to end CAC. This commit also adds a call to said callback if after a radar event we see the CAC is no longer relevant Signed-off-by: Orr Mazor <Orr.Mazor@tandemg.com> Reviewed-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com> Link: https://lore.kernel.org/r/20191222145449.15792-1-Orr.Mazor@tandemg.com [slightly reformat/reword commit message] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2020-01-14net: mac80211: use skb_list_walk_safe helper for gso segmentsJason A. Donenfeld
This is a conversion case for the new function, keeping the flow of the existing code as intact as possible. We also switch over to using skb_mark_not_on_list instead of a null write to skb->next. Finally, this code appeared to have a memory leak in the case where header building fails before the last gso segment. In that case, the remaining segments are not freed. So this commit also adds the proper kfree_skb_list call for the remainder of the skbs. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: David S. Miller <davem@davemloft.net>
