Just checking, I did
Code:
emerge --sync

and
Code:
emerge --update wpa_supplicant


Is this enough for me to have the latest update with the fix for the famous Krack? https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=319c86d1f048618da77824081843a43f049eadb5

Elaman,

Maybe ... what version do you get?
2.6-r3 is fixed

Perfect.
Code:
emerge --info
returns just that:
Code:
wpa_supplicant-2.6-r3


Still, thanks for the confirmation!

I upgraded wpa_supplicant-2.6 to r3 and it broke my wifi. The wpa_supplicant daemon would load successfully with no errors. Ifconfig showed my wifi interface with no issues. But I could not scan in wpa_cli and dhcpcd <interface> would not really get lease me a ipaddress(even though it didn't complain). Also, wpa_gui would not load.

I rolled back to wpa_supplicant-2.6 and my wifi worked again.

Any suggestions?

wpa_cli won't scan when associated on some drivers.
dhcpcd should timeout if the carrier is not up. However, if the kernel thinks it's up but it's really not due to wpa_supplicant issue when dhcpcd will negoitate an IPv4LL address so this could be expected behaviour.

FWIW, I have several wpa_supplicant versions (although non Gentoo) and they still work fine (Debian derivative patched 2.4, NetBSD patched 2.6 and git head on a Debian derivative). I would look for errors in wpa_supplicant and see if you can spot the failure there.

If you can read c patchset with comments, you may find the culprit there:
https://gitweb.gentoo.org/repo/gentoo.git/commit/net-wireless/wpa_supplicant/files/2017-1?id=319c86d1f048618da77824081843a43f049eadb5

8 patches in total, I wonder if they can be applied individually. to identify which breaks the wifi. Just comment out patch(es) in ebuild.
