Josh Bleecher Snyder 9d542e08e2 wgengine/magicsock: always run ReceiveIPv6 ... One of the consequences of the bind refactoring in 6f23087175 is that attempting to bind an IPv6 socket will always result in c.pconn6.pconn being non-nil. If the bind fails, it'll be set to a placeholder packet conn that blocks forever. As a result, we can always run ReceiveIPv6 and health check it. This removes IPv4/IPv6 asymmetry and also will allow health checks to detect any IPv6 receive func failures. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>		2021-04-28 11:07:14 -07:00
