That seems wrong. This change was done because you might otherwise get stray SCAN_DONE signals when the scan is in progress -- we should still be getting a SCAN_DONE signal later from the supplicant when we get the scan results. The issue here is that the scan may not be done correctly on return from suspend, but I doubt that forcing a SCAN_DONE to look at the scan results again is the right way to go about fixing this.
Since the issue can be resolved by asking the driver to scan again (via wpa or via iw dev wlan0 scan) and only seems to apply for iwlwifi (as far as I've heard), it would probably really point to either a driver or a wpasupplicant bug. Tony, what are your thoughts on this? I know you recently spent a lot of time looking at the scanning/scan results logic? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1585863 Title: WiFi malfunction after suspend & resume stress Status in NetworkManager: New Status in OEM Priority Project: New Status in OEM Priority Project xenial series: New Status in network-manager package in Ubuntu: New Bug description: Description: Ubuntu Yakkety Yak (development branch) Release: 16.10 Packages: libnm-glib-vpn1:amd64 1.2.2-0ubuntu2 libnm-glib4:amd64 1.2.2-0ubuntu2 libnm-util2:amd64 1.2.2-0ubuntu2 libnm0:amd64 1.2.2-0ubuntu2 network-manager 1.2.2-0ubuntu2 Reproduce steps: 1. Install fwts by `sudo apt-get install fwts`. 2. Run the suspend & resume stress test. sudo fwts s3 --s3-multiple=30 --s3-min-delay=10 --s3-max-delay=10 --s3-delay-delta=5 Expected result: The WiFi still functioned. Actual result: The WiFi can not connect to any access point and we have to execute `sudo wpa_cli scan` manually to make it work again. P.S. Ubuntu 16.04 also has the same issue.
