You have been subscribed to a public bug: Kernel version 3.19, currently being used as the vivid LTS kernel, includes support for ipvlan. But at its current state it is unusable as simply removing an interface with an ip address attached will cause a kernel crash. The fix is already upstream:
https://github.com/torvalds/linux/commit/27705f7085ce2e124fac4c280ce824962cc90bb6 Reproducing this is easy (requires a recent version of iproute2, with support for ipvlan, such as the one in debian/experimental): ip netns add ns0 ip link add link eth0 ipvl0 type ipvlan mode L3 ip link set dev ipvl0 netns ns0 ip netns exec ns0 bash ip link set dev ipvl0 up ip -4 addr add 192.168.0.10/24 dev ipvl0 ip link del dev ipvl0 The last line will cause a kernel crash, with a calltrace that looks like this: https://gist.github.com/fabiokung/b360cb2f3bdf2fb36c8b Can we get the fixes backported to the 3.19 LTS kernel from vivid? Ideally we would like to have the whole patchset backported: https://github.com/torvalds/linux/commit/d91e9015c78af1dc1f8ac4fdcf6118dbc2401668 and https://github.com/torvalds/linux/commit/8172ba51e257fdd353010cd7caaa37c8bc9eb44a ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- ipvlan module causes kernel crashes (backport fixes from upstream) https://bugs.launchpad.net/bugs/1475434 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
