Entering '*' in the 'Src IP' or 'Dest IP' field of the ESP SA does not work as
expected.

The reason is that at the beginning of the function filter_address_match()
(packet-ipsec.c) the length of the filter is compared with the length of the ip
address, so it always returns false. 

I changed the condition such that it now matches the analogous condition in the
function filter_spi_match() (same file).

Attached you find a patch for packet-ipsec.c against trunk-1.8
