Hello, I am looking for people to give feedback on a review I've opened to improve the locking in vlan(4). Anyone who's done a fair amount of destroying vlan interfaces on live systems has probably run into panics in if_vlan. This is because there is no real synchronization to prevent a vlan interface from being destroyed while there are mbufs in the network going through its functions. Isilon's customers have hit panics like this, so I've reworked the locking to make destroying vlans safe on live systems, and fixed every instance of unsafe access I could find.
If anyone has an interest in this work please review the revision: https://reviews.freebsd.org/D11370 Thanks, Matt Joras _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
