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-
disco' to 'verification-done-disco'. If the problem still exists, change
the tag 'verification-needed-disco' to 'verification-failed-disco'.

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. Thank you!

Title:
  ipv4: enable route flushing in network namespaces

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Disco:
  Fix Committed

Bug description:
  SRU Justification

  Impact: Tools such as vpnc try to flush routes when run inside network 
namespaces by writing 1 into /proc/sys/net/ipv4/route/flush. This
  currently does not work because flush is not enabled in non-initial network 
namespaces. Users have complained about this at various times (cf. Link: 
https://github.com/lxc/lxd/issues/4257).

  Fix: Enable /proc/sys/net/ipv4/route/flush inside non-initial network
  namespaces.

  Regression Potential: None, since this didn't use to work before.
  Since routes are per network namespace it is safe to enable
  /proc/sys/net/ipv4/route/flush in there.

  Test Case: Tested with LXD on a kernel with the patch applied and by
  running vpnc successfully.

  Target Kernels: All LTS kernels starting from 4.15. Kernel 5.3 has the
  patchset upstream.
