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.

The commit that introduces this bug has not been identified, but it's here at least from Xenial (4.4). This was fixed in the requested backport (from 5.2). == Fix == Backport the requested patches to Disco (5.0), Bionic (4.15) and Xenial (4.4). == Risk of Regregression == The change slightly modifies the target IPv6 address in neighbor resolution engine. Risk should be low and limited to ipv6. --- With an IPv6 raw socket, packets may be dropped during the neighbour resolution. It is fixed upstream by these patches: 9b1c1ef13b35 ipv6: constify rt6_nexthop() 2c6b55f45d53 ipv6: fix neighbour resolution with raw socket https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=9b1c1ef13b35fa35051b635ca9fbda39fe6bbc70 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=2c6b55f45d53420d8310d41310e0e2cd41fe073f The detail of the bug is explained in the second patch.
