-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello all, [1.] One line summary of the problem: Commit 8dbb000ee73b in Linux 5.2 makes my wifi stop transferring packets under a certain load. [2.] Full description of the problem/report: This is on a Lenovo Thinkpad Yoga 12 with an Intel 7265D wifi card. Reverting the commit in 5.2.4 indeed fixes the issue for me. The following versions (non-exhaustive) cause my wifi to stop working: 5.2 5.2.2 5.2.3 5.2.4 5.3-rc1 The following versions work fine: 5.1 5.1.21 5.2.3 with 8dbb000ee73b reverted 5.2.4 with 8dbb000ee73b reverted - --- Reproduction Unfortunately I don't have a recipe for someone else to reproduce the problem. I can only say how I can evoke it. It seems timing related. Laptop connected to an 802.11ac access point, on either 2.4 GHz or 5 GHz. I've come to suspect it is much more likely to trigger on 5 GHz, but I didn't pay attention to it initially so I have too little data. Laptop runs OpenVPN Server that handles my daily backups runs the command: rsync -vrltH --delete -pgjo -D --numeric-ids -S --stats --itemize-changes --acls --xattrs --exclude-from=/srv/backup/dirvish/terrence/20190726-2110/exclude --link-dest=/srv/backup/dirvish/terrence/20190725-1937/tree terrence.guestwlan.lucas.digitalbrains.com:/root/backupmnt/ /srv/backup/dirvish/terrence/20190726-2110/tree This will rsync over SSH the latest data on the laptop's storage, using the data from the previous backup to avoid transferring existing data (--link-dest argument). Conventional hard disk in the server, SSD in the laptop. Laptop is full disk encrypted with LUKS, dm-crypt. This is the scenario that triggers the problem for me. Routing is asymmetric: while packets from laptop to backup server are over OpenVPN, packets from server to laptop are routed directly over the wireless interface. Connection is IPv6. A succesful backup would take about half an hour. Usually pretty quickly, but generally within the first backup, and once only on the second try, my wireless connection would just die. Nothing is logged, but all IP connections over wireless drop away. I think it's transmission that is failing, as I still see incoming packets in Wireshark. I didn't run Wireshark in the attached kernel log, though. I manage my network interfaces using Debian's ifupdown and wpa_action. Issuing # wpa_action wlp4s0 stop # ifup wlp4s0 brings it back to life. Debian's ifupdown calls the supplicant as: /sbin/wpa_supplicant -s -B -P /run/wpa_supplicant.wlp4s0.pid -i wlp4s0 -W -D nl80211,wext -c /etc/wpa_supplicant/wpa_supplicant.conf Attached is a dmesg trace for 5.2.4. I enabled: CONFIG_MAC80211_HT_DEBUG=y CONFIG_MAC80211_VERBOSE_PS_DEBUG=y CONFIG_MAC80211_VERBOSE_DEBUG=y The timeline is as follows: [Uptime in seconds]: [event] 92: Start backup 231: Wifi drops out 276: wpa_action wlp4s0 stop, ifup wlp4s0 (networking is restored) 380: Wifi drops out again 415: wpa_action wlp4s0 stop, ifup wlp4s0 (networking is restored) [3.] Keywords (i.e., modules, networking, kernel): networking, wireless, mac80211, iwlwifi [4.] Kernel information [4.1.] Kernel version (from /proc/version) Linux version 5.2.4 (peter@tweek) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1)) #1 SMP Sun Jul 28 10:37:15 CEST 2019 [4.2.] Kernel .config file: See attachment.
