Date: Wed, 20 Jan 2021 15:45:44 GMT From: Cy Schubert <cy@FreeBSD.org> To: src-committers@FreeBSD.org, dev-commits-src-all@FreeBSD.org, dev-commits-src-main@FreeBSD.org Subject: git: d70886d06316 - main - wpa_supplicant uses PF_ROUTE to return the routing table in order to determine the length of the routing table buffer. As of 81728a538d24 wpa_supplicant is started before the routing table has been populated resulting in the length of zero to be returned. This causes wpa_supplicant to loop endlessly. (The workaround is to kill and restart wpa_supplicant as by the time it is restarted the routing table is populated.) Message-ID: <202101201545.10KFjiYU097815@gitrepo.freebsd.org>

As of 81728a538d24 wpa_supplicant is started before the routing table has been populated resulting in the length of zero to be returned. This causes wpa_supplicant to loop endlessly. (The workaround is to kill and restart wpa_supplicant as by the time it is restarted the routing table is populated.) (Personally, I was not able to reproduce this unless wlan0 was a member of lagg0. However, others experienced this problem on standalone wlan0.)
