From: Steffen Klassert [ Upstream commit 62cf27e52b8c9a39066172ca6b6134cb5eaa9450 ] A recent patch removed the dst_free() on the allocated dst_entry in ipv6_blackhole_route(). The dst_free() marked the dst_entry as dead and added it to the gc list. I.e. it was setup for a one time usage. As a result we may now have a blackhole route cached at a socket on some IPsec scenarios. This makes the connection unusable. Fix this by marking the dst_entry directly at allocation time as 'dead', so it is used only once. Fixes: 587fea741134 ("ipv6: mark DST_NOGC and remove the operation of dst_free()") Reported-by: Tobias Brunner Signed-off-by: Steffen Klassert Signed-off-by: David S.
