Package: src:linux Version: 3.16.39-1 Severity: important Tags: patch Dear Maintainer,
Under some circumstances, when an ipv6 peer addresse is removed, there is a refcnt problem: kernel:[ 9614.220549] unregister_netdevice: waiting for lo to become free. Usage count = 2 This bug has been fixed by the following upstream patch: f24062b07dda ipv6: fix a refcnt leak with peer addr You may also consider backporting thoses patches: e7478dfc4656 ipv6: use addrconf_get_prefix_route() to remove peer addr 8e3d5be73681 ipv6: Avoid double dst_free http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f24062b07dda http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e7478dfc4656f http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8e3d5be736810 Regards, Nicolas -- Package-specific info: ** Version: Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.39-1 (2016-12-30) ** Command line: BOOT_IMAGE=/boot/vmlinuz-3.16.0-4-amd64 root=/dev/mapper/6WIND-debian8 ro console=ttyS0,115200n8 quiet ** Not tainted ** Kernel log: [ 5.658529] systemd[1]: Starting Root Slice.
