| H A D | udp.h | diff 64f0f5d18a47c703c85576375cc010e83dac6a48 Fri Aug 25 14:31:01 CEST 2017 Paolo Abeni <pabeni@redhat.com> udp6: set rx_dst_cookie on rx_dst updates
Currently, in the udp6 code, the dst cookie is not initialized/updated
concurrently with the RX dst used by early demux.
As a result, the dst_check() in the early_demux path always fails,
the rx dst cache is always invalidated, and we can't really
leverage significant gain from the demux lookup.
Fix it adding udp6 specific variant of sk_rx_dst_set() and use it
to set the dst cookie when the dst entry is really changed.
The issue is there since the introduction of early demux for ipv6.
Fixes: 5425077d73e0 ("net: ipv6: Add early demux handler for UDP unicast")
