description |
The upstream commit 2f3ab6221e4c ("tuntap: correctly set SOCKWQ_ASYNC_NOSPACE") is missing.
Without this patch, userspace apps that use tuntap may be blocked.

[SRU Justification]
== Impact ==
1bd4978a88ac2 ("tun: honor IFF_UP in tun_get_user()") which is part of kernel v4.5 introduced an issue where userspace processes might not get notified if a link comes up after initially being down. 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.
