* mac80211: fix QCA9561 PA biasThibaut VARÈNE2022-04-191-0/+47
| | | | | | | | | | | | | | | This patch fixes an invalid TX PA DC bias level on QCA9561, which results in a very low output power and very low throughput as devices are further away from the AP (compared to other 2.4GHz APs), following a suggestion from nbd[1]. This patch has been submitted upstream[2].

* kernel: ath10k: provide a build variant for small RAM devicesNick Hainke2022-01-023-4/+82
| | | | | | | | | | | | | | | | | | | | | | | | Based on: 1ac627024de9 ("kernel: ath10k-ct: provide a build variant for small RAM devices") Like described in the ath10k-ct-smallbuffers version, oom-killer gets triggered frequently by devices with small RAM. That change is necessary for many community mesh networks which use ath10k based devices with too little RAM. The -ct driver has been proven unstable if used with 11s meshing and only wave2 chipsets are supporting 11s. Freifunk Berlin is nowadays assembling its firmware-based completely of vanilla OpenWRT with some package additions which are made through the imagebuilder. Therefore we cannot take the approach other freifunk communities have taken to maintain that patch downstream [1]. Other communities consider these devices as broken and that change would pretty much give those devices a second life [2].

* mac80211: print an error if wifi teardown failsBob Cantor2021-06-301-0/+4
| | | | | | | | | | drv_mac80211_teardown fails silently if the device to be torn down is not defined. This commit prints an error message. branches affected: trunk, 21.02 Signed-off-by: Bob Cantor <coxede6557@w3boats.com> (cherry-picked from commit 3933e29d1b87c713167cf4730b68e5f18af4f140)
* mac80211: always call wireless_set_data (FS#3784)Bob Cantor2021-06-301-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When wifi is turned off, drv_mac80211_teardown sometimes fails (silently) because the device to be torn down is not defined. This situation arises if drv_mac80211_setup was called twice when wifi was turned on. This commit ensures that the device to be torn down is always defined in drv_mac80211_teardown. Steps to reproduce: 1) Use /sbin/wifi to turn on wifi. uci set wireless.@wifi-iface[0].disabled=0 uci set wireless.@wifi-device[0].disabled=0 uci commit wifi 2) Use /sbin/wifi to turn off wifi. uci set wireless.@wifi-device[0].disabled=1 uci commit wifi 3) Observe that wifi is still up. branches affected: trunk, 21.02 Signed-off-by: Bob Cantor <coxede6557@w3boats.com> (cherry-picked from commit d515f6b6cde357bf480d32a7387f07ea40e85e52)
* mac80211: fix no_reload logic (FS#3902)Bob Cantor2021-06-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If drv_mac80211_setup is called twice with the same wifi configuration, then the second call returns early with error HOSTAPD_START_FAILED. (wifi works nevertheless, despite the fact that setup is incomplete. But "ubus call network.wireless status" erroneously reports that radio0 is down.) The relevant part of drv_mac80211_setup is, if [ "$no_reload" != "0" ]; then add_ap=1 ubus wait_for hostapd local hostapd_res="$(ubus call hostapd config_add "{\"iface\":\"$primary_ap\", \"config\":\"${hostapd_conf_file}\"}")" ret="$?" [ "$ret" != 0 -o -z "$hostapd_res" ] && { wireless_setup_failed HOSTAPD_START_FAILED return } wireless_add_process "$(jsonfilter -s "$hostapd_res" -l 1 -e @.pid)" "/usr/sbin/hostapd" 1 1 fi This commit sets no_reload = 0 during the second call of drv_mac80211_setup. It is perhaps worth providing a way to reproduce the situation where drv_mac80211_setup is called twice. When /sbin/wifi is used to turn on wifi, uci set wireless.@wifi-iface[0].disabled=0 uci set wireless.@wifi-device[0].disabled=0 uci commit wifi /sbin/wifi makes the following ubus calls, ubus call network reload ubus call network.wireless down ubus call network.wireless up The first and third ubus calls both call drv_mac80211_setup, while the second ubus call triggers wireless_device_setup_cancel. So the call sequence becomes, drv_mac80211_setup wireless_device_setup_cancel drv_mac80211_setup In contrast, when LuCI is used to turn on wifi only a single call is made to drv_mac80211_setup. branches affected: trunk, 21.02 Signed-off-by: Bob Cantor <coxede6557@w3boats.com> (cherry-picked from commit a29ab3b79affb62fda82e0825ed811eaf482dd3c)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
