* mac80211: backport upstream fixes for FragAttacksFelix Fietkau2021-05-1223-7/+1466
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the patch series description: Several security issues in the 802.11 implementations were found by Mathy Vanhoef (New York University Abu Dhabi), who has published all the details at https://papers.mathyvanhoef.com/usenix2021.pdf Specifically, the following CVEs were assigned: * CVE-2020-24586 - Fragmentation cache not cleared on reconnection * CVE-2020-24587 - Reassembling fragments encrypted under different keys * CVE-2020-24588 - Accepting non-SPP A-MSDU frames, which leads to payload being parsed as an L2 frame under an A-MSDU bit toggling attack * CVE-2020-26139 - Forwarding EAPOL from unauthenticated sender * CVE-2020-26140 - Accepting plaintext data frames in protected networks * CVE-2020-26141 - Not verifying TKIP MIC of fragmented frames * CVE-2020-26142 - Processing fragmented frames as full frames * CVE-2020-26143 - Accepting fragmented plaintext frames in protected networks * CVE-2020-26144 - Always accepting unencrypted A-MSDU frames that start with RFC1042 header with EAPOL ethertype * CVE-2020-26145 - Accepting plaintext broadcast fragments as full frames * CVE-2020-26146 - Reassembling encrypted fragments with non-consecutive packet numbers * CVE-2020-26147 - Reassembling mixed encrypted/plaintext fragments In general, the scope of these attacks is that they may allow an attacker to * inject L2 frames that they can more or less control (depending on the vulnerability and attack method) into an otherwise protected network; * exfiltrate (some) network data under certain conditions, this is specific to the fragmentation issues. A subset of these issues is known to apply to the Linux IEEE 802.11 implementation (mac80211). Where it is affected, the attached patches fix the issues, even if not all of them reference the exact CVE IDs. In addition, driver and/or firmware updates may be necessary, as well as potentially more fixes to mac80211, depending on how drivers are using it. Specifically, for Intel devices, firmware needs to be updated to the most recently released versions (which was done without any reference to the security issues) to address some of the vulnerabilities. To have a single set of patches, I'm also including patches for the ath10k and ath11k drivers here. We currently don't have information about how other drivers are, if at all, affected.

* ath9k: fix transmitting to stations in dynamic SMPS modeFelix Fietkau2021-02-141-0/+49
| | | | | | | | | | When transmitting to a receiver in dynamic SMPS mode, all transmissions that use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to give the receiver's extra chains some time to wake up. This fixes the tx rate getting stuck at <= MCS7 for some clients, especially Intel ones, which make aggressive use of SMPS. Signed-off-by: Felix Fietkau <nbd@nbd.name>

| | | | | | | | | | | The removed patches were applied upstream. Remove the 300-mac80211-optimize-skb-resizing.patch. This patch was not applied upstream, but it conflicts with upstream changes and needs bigger changes. It was applied with Felix to remove this patch for now. It should be reworked and then send upstream later. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

* mac80211: rt2x00: save survey for every channel visitedMarkov Mikhail2020-10-211-0/+183
| | | | | | | | | | | | | | | rt2800 olny gives you survey for current channel. Survey-based ACS algorithms are failing to perform their job when working with rt2800. Make rt2800 save survey for every channel visited and be able to give away that information. There is a bug registred https://dev.archive.openwrt.org/ticket/19081 and this patch solves the issue.

* mac80211: fix memory leak on filtered powersave framesFelix Fietkau2020-10-171-0/+55
| | | | | | | | | | After the status rework, ieee80211_tx_status_ext is leaking un-acknowledged packets for stations in powersave mode. To fix this, move the code handling those packets from __ieee80211_tx_status into ieee80211_tx_status_ext Reported-by: Tobias Waldvogel <tobias.waldvogel@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* rt2x00: mt7620: differentiate based on SoC's CHIP_VERDaniel Golle2020-10-092-0/+547
| | | | | | | | | | | | | | | | | | | | | | | The vendor driver does things differently based on what it finds in the SoC's CHIP_VER register, which should tell whether this is MT7620N or MT7620A (PKG) and probably also the revision (VER) and most likely also something about the silicon implementer (ECO). Introduce codepaths just like the ones in the vendor driver to handle the different chips properly. Some of those paths are most likely dead code and left-overs from FPGA versions or early prototypes of the chip. It'd thus be great if people can post their kernel logs, at least the line telling the chip version and eco, so we know what's actually out there in the wild -- all I could find is [ 0.000000] SoC Type: Ralink MT7620A ver:2 eco:6 and [ 0.000000] SoC Type: Ralink MT7620N ver:2 eco:6 which would make things easier, as then we really just need to know whether it's MT7620N or MT7620A and not care about FPGA or prototypes with ver <= 1 and eco <= 2.
