mac80211: fix wrong 160/80+80 MHz setting

2020-02-14T08:54:12+00:00

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. Fix is to verify STA has 160/80+80 MHz capability before increasing its width to > 80MHz. The "support_80_80" and "support_160" setting is based on: "Table 9-272 — Setting of the Supported Channel Width Set subfield and Extended NSS BW Support subfield at a STA transmitting the VHT Capabilities Information field" From "Draft P802.11REVmd_D3.0.pdf" Signed-off-by: Aviad Brikman Signed-off-by: Shay Bar Link: https://lore.kernel.org/r/20200210130728.23674-1-shay.bar@celeno.com Signed-off-by: Johannes Berg

mac80211: consider more elements in parsing CRC

2020-02-07T10:44:02+00:00

We only use the parsing CRC for checking if a beacon changed, and elements with an ID > 63 cannot be represented in the filter. Thus, like we did before with WMM and Cisco vendor elements, just statically add these forgotten items to the CRC: - WLAN_EID_VHT_OPERATION - WLAN_EID_OPMODE_NOTIF I guess that in most cases when VHT/HE operation change, the HT operation also changed, and so the change was picked up, but we did notice that pure operating mode notification changes were ignored.

mac80211: fix quiet mode activation in action frames

2020-02-07T10:44:02+00:00

Previously I intended to ignore quiet mode in probe response, however I ended up ignoring it instead for action frames. As a matter of fact, this path isn't invoked for probe responses to start with. Just revert this patch.

mac80211: use more bits for ack_frame_id

2020-02-07T10:32:27+00:00

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.

mac80211: Fix TKIP replay protection immediately after key setup

2020-01-15T08:52:12+00:00

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).

cfg80211: Fix radar event during another phy CAC

2020-01-15T08:50:48+00:00

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 Reviewed-by: Sergey Matyukevich Link: https://lore.kernel.org/r/20191222145449.15792-1-Orr.Mazor@tandemg.com [slightly reformat/reword commit message] Signed-off-by: Johannes Berg

net: mac80211: use skb_list_walk_safe helper for gso segments

2020-01-14T19:48:41+00:00

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 Signed-off-by: David S. Miller
