Systemd fails to rename VF interface: kernel: mlx4_core 0002:00:02.0 eth2: joined to eth1 kernel: hv_netvsc 33b7a6f9-6736-451f-8fce-b382eaa50bee eth1: VF registering: eth2 kernel: hv_netvsc 33b7a6f9-6736-451f-8fce-b382eaa50bee eth1: Data path switched to VF: eth2 kernel: mlx4_en: eth2: Link Up NetworkManager[750]: <info> [1502200557.0821] device (eth2): link connected NetworkManager[750]: <info> [1502200557.1004] manager: (eth2): new Ethernet device (/org/freedesktop/NetworkManager/Devices/6) systemd-udevd[6942]: Error changing net interface name 'eth2' to 'enP2p0s2': Device or resource busy systemd-udevd[6942]: could not rename interface '6' from 'eth2' to 'enP2p0s2': Device or resource busy With some debug added I figured out what's wrong: __netvsc_vf_setup() does dev_open() which sets IFF_UP flag on the interface. When systemd tries to rename the interface we get into dev_change_name() and this fails with -EBUSY when (dev->flags & IFF_UP). The issue is of less importance as we're not supposed to configure VF interface now. However, we may still want to get a stable name for it. Any idea how this can be fixed? -- Vitaly _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
