Created attachment 442014 [details] Skript reverting MODULE_ALIAS_CRYPTO back to MODULE_ALIAS. Dear kernel developers, after a kernel update from 3.10.66 to 3.10.67 (found by a bisection search), the wifi stopped working. I also tried latest kernels of version 3.12, 3.14, 3.18, 4.1, and 4.4 without success. After some investigation I have found out that a security patch introducing MODULE_ALIAS_CRYPTO instead of MODULE_ALIAS caused the problem. In the attachment you can find the script reverting this change (tested on kernel 3.10), however, it is probably not a good idea to apply it. I also tried to update udev and kmod packages, also without success. It is interesting that in the gentoo-based SystemRescueCd distribution the wifi works without patched kernel. Is it possible that it works only for the systemd init system? Or is initramfs required to have wifi working? I copied the kernel configuration from the aforementioned distribution to test whether there is not problem in the configuration, but it did not helped. Note that only the support for initramfs was disabled and the support for OpenRC system was enabled. The configuration of wpa_supplicant.conf was the same and the same modules were loaded. That is the error output obtained after a kernel update: Successfully initialized wpa_supplicant nl80211: Could not re-add multicast membership for vendor events: -2 (No such file or directory) wlan0: SME: Trying to authenticate with ...

Hovewer, this module is not necessary for the wifi to work.

It seems that the same problem also occurred in kernel 3.12, see http://www.spinics.net/lists/linux-crypto/msg13103.html. Based on clues provided in the link, I have found out that module arc4 has been blacklisted and it caused the problem. So apparently, the behaviour of module loading changed after replacing MODULE_ALIAS with MODULE_ALIAS_CRYPTO.
