I can confirm the segfault error on my Belkin 3200 device with latest OpenWRT snapshot builds.

airend commented 1 year ago

It's caused by the recently added support for the port isolated flag (commit 978c1f9eed07504cc0b84f72ee7384aab722386a). Maybe it's missing a check in flow.c. Either way, it happens regardless of WED support (same crash on mt7621/mt7615). I just reverted that commit for now.

@jww-cw, @schuettecarsten, it's fixed in 8be8bb9df789b53a68f08298f610648ebded6063 (https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=83d3e255f1cc7ca59e51f02857cef2e004d946dc).

@airend yep, it's fixed.
