bfd: fix buffer leak when cannot send periodic packets
When a periodic BFD packet cannot be sent because the interface is disabled, the allocated buffer needs to be freed. This currently will occur for IPv4 sessions. However, buffers will leak for IPv6 sessions as in this case, bfd_transport_control_frame() and bfd_transport_udp6() will not indicate failure. With this fix, stop always returning success in bfd_transport_udp6() and start returning the actual return value. Type: fix Change-Id: I5fa4d9206e32cccae3053ef24966d80e2022fc81 Signed-off-by: Alexander Chernavin <achernavin@netgate.com>
