* mac80211: print an error if wifi teardown failsBob Cantor2021-06-281-0/+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>
* mac80211: always call wireless_set_data (FS#3784)Bob Cantor2021-06-281-4/+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>
* mac80211: fix no_reload logic (FS#3902)Bob Cantor2021-06-281-0/+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>

The brcmf_driver_work workqueue was removed in brcmfmac with kernel 5.10.42, the asynchronous call was covered to a synchronous call. There is no need to wait any more.

* mac80211: split ath patch in dedicated subdirAnsuel Smith2021-06-0449-0/+8
| | | | | | | | | | The ath patch number is already large and adding other patch for ath11k will add more confusion with the patch numbering. Since the support of ath11k based device is imminent, prepare the mac80211 ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k (empty for now).

* 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.

| | | | | | | | | | 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.
