This was fixed in the requested backport (from 4.17). == Fix == Backport the requested patch to Bionic (4.15). Xenial (4.4) is not affected and Disco and later already contain that fix. == Risk of Regregression == The change only slightly modifies a very specific protocol function. Risk should be low and limited to tuntap. --- The upstream commit 2f3ab6221e4c ("tuntap: correctly set SOCKWQ_ASYNC_NOSPACE") is missing. Without this patch, userspace apps that use tuntap may be blocked. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2f3ab6221e4c To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1830756/+subscriptions -- 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
