wifi: mac80211: fix crash in beacon protection for P2P-device

2022-10-10T07:51:25+00:00

If beacon protection is active but the beacon cannot be decrypted or is otherwise malformed, we call the cfg80211 API to report this to userspace, but that uses a netdev pointer, which isn't present for P2P-Device. Fix this to call it only conditionally to ensure cfg80211 won't crash in the case of P2P-Device. This fixes CVE-2022-42722.

wifi: mac80211: fix decap offload for stations on AP_VLAN interfaces

2022-10-07T12:43:29+00:00

Since AP_VLAN interfaces are not passed to the driver, check offload_flags on the bss vif instead. Reported-by: Howard Hsu Fixes: 80a915ec4427 ("mac80211: add rx decapsulation offload support") Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

wifi: mac80211: do not drop packets smaller than the LLC-SNAP header on fast-rx

2022-10-07T12:38:58+00:00

Since STP TCN frames are only 7 bytes, the pskb_may_pull call returns an error. Instead of dropping those packets, bump them back to the slow path for proper processing.

Kalle Valo says: ==================== wireless-next patches for v6.1 Few stack changes and lots of driver changes in this round. brcmfmac has more activity as usual and it gets new hardware support. ath11k improves WCN6750 support and also other smaller features. And of course changes all over. Note: in early September wireless tree was merged to wireless-next to avoid some conflicts with mac80211 patches, this shouldn't cause any problems but wanted to mention anyway. Major changes: mac80211 - refactoring and preparation for Wi-Fi 7 Multi-Link Operation (MLO) feature continues brcmfmac - support CYW43439 SDIO chipset - support BCM4378 on Apple platforms - support CYW89459 PCIe chipset rtw89 - more work to get rtw8852c supported - P2P support - support for enabling and disabling MSDU aggregation via nl80211 mt76 - tx status reporting improvements ath11k - cold boot calibration support on WCN6750 - Target Wake Time (TWT) debugfs support for STA interface - support to connect to a non-transmit MBSSID AP profile - enable remain-on-channel support on WCN6750 - implement SRAM dump debugfs interface - enable threaded NAPI on all hardware - WoW support for WCN6750 - support to provide transmit power from firmware via nl80211 - support to get power save duration for each client - spectral scan support for 160 MHz wcn36xx - add SNR from a received frame as a source of system entropy * tag 'wireless-next-2022-09-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (231 commits) wifi: rtl8xxxu: Improve rtl8xxxu_queue_select wifi: rtl8xxxu: Fix AIFS written to REG_EDCA_*_PARAM wifi: rtl8xxxu: gen2: Enable 40 MHz channel width wifi: rtw89: 8852b: configure DLE mem wifi: rtw89: check DLE FIFO size with reserved size wifi: rtw89: mac: correct register of report IMR wifi: rtw89: pci: set power cut closed for 8852be wifi: rtw89: pci: add to do PCI auto calibration wifi: rtw89: 8852b: implement chip_ops::{enable,disable}_bb_rf wifi: rtw89: add DMA busy checking bits to chip info wifi: rtw89: mac: define DMA channel mask to avoid unsupported channels wifi: rtw89: pci: mask out unsupported TX channels iwlegacy: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper ipw2x00: Replace zero-length array with DECLARE_FLEX_ARRAY() helper wifi: iwlwifi: Track scan_cmd allocation size explicitly brcmfmac: Remove the call to "dtim_assoc" IOVAR brcmfmac: increase dcmd maximum buffer size brcmfmac: Support 89459 pcie brcmfmac: increase default max WOWL patterns to 16 cw1200: fix incorrect check to determine if no element is found in list ... ==================== Link: https://lore.kernel.org/r/20220930150413.A7984C433D6@smtp.kernel.org Signed-off-by: Jakub Kicinski

net-next: skbuff: refactor pskb_pull

2022-09-30T11:31:46+00:00

pskb_may_pull already contains all of the checks performed by pskb_pull. Use pskb_may_pull for validation in pskb_pull, eliminating the duplication and making __pskb_pull obsolete. Replace __pskb_pull with pskb_pull where applicable. Signed-off-by: Richard Gobert Signed-off-by: David S. Miller

wifi: mac80211: make smps_mode per-link

2022-09-06T08:11:44+00:00

The SMPS power save mode needs to be per-link rather than being shared for all links. As such, move it into struct ieee80211_link_sta. Signed-off-by: Benjamin Berg Signed-off-by: Johannes Berg

wifi: mac80211: use correct rx link_sta instead of default

wifi: mac80211: set link_sta in reorder timeout

2022-09-06T08:09:55+00:00

Now that we have a link_sta pointer in the rx struct we also need to fill it in all the cases. It didn't matter so much until now as we weren't using it, but the code should really be able to assume that if the rx.sta is set, so is rx.link_sta.
