That's the value add a distro has :) > That is a valid fact, however, fixing broken 802.11w, a required part of the standard, feels like a valid bug fix to me. Especially since in 4.19.5 a patch to fix monitor mode was added for the same driver. Interestingly when I asked for the monitor mode patch to be ported it was initially refused and then just kind of happened a few weeks later. In this case I have a much stronger case, a required feature of the wifi driver is broken, and this is an LTS kernel. I also feel compelled to point out that this doesn't matter at all to me personally. I will be on 4.20 ten seconds after it comes out, but many many people use distros which run LTS kernels like 4.19 for years. Those people will be missing a required feature for wpa3, and APs with support (and certification) are already appearing. So I close by politely requesting that this bug gets fixed :-) -Zero > Regards, > Matthias > > > Just in case it helps to confirm what is needed, here is the error > > from wpa_supplicant when trying to connect to an 802.11w AP > > wlan0: WPA: Failed to configure IGTK to the driver > > wlan0: RSN: Failed to configure IGTK > > > > thanks, > > Zero > > > >> > >> Regards, > >> Lorenzo > >> > >>> > >>> Thanks, > >>> Zero > > > > _______________________________________________ > > Linux-mediatek mailing list > > Linux-mediatek@xxxxxxxxxxxxxxxxxxx > > http://lists.infradead.org/mailman/listinfo/linux-mediatek > >
