2019-08-29 14:42:47 Nicolas Dichtel description 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. [SRU Justification] == Impact == IPv6 packets may be dropped during the neighbor resolution when a userspace program uses IPv6 raw sockets. 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.
