[Bug 1830756] Re: tuntap: correctly set SOCKWQ_ASYNC_NOSPACE
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1830756] Re: tuntap: correctly set SOCKWQ_ASYNC_NOSPACE
** Description changed:
+ [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.
+
+ ---
+
The upstream commit 2f3ab6221e4c ("tuntap: correctly set
SOCKWQ_ASYNC_NOSPACE") is missing.
Without this patch, userspace apps that use tuntap may be blocked.
