1. get rid of the "$*" fetish.
2. more consistency (not complete .. yet) with RUMP_SERVER setting
3. white space (esp around pipe ('|') symbols.)
4. drop unnecessary \ line joining.
The test cases transfer data over TCP by using nc with IPsec just enabled
(no SA/SP is configured) and confirm the commit "Fix diagnostic assertion
failure in ipsec_init_policy" really fixes the issue.
- Check if setkey correctly handles algorithms for AH/ESP
- Check IPsec of transport mode with AH/ESP over IPv4/IPv6
- Check IPsec of tunnel mode with AH/ESP over IPv4/IPv6
ftp with rumphijack is unstable probably because ftp uses siglongjmp from
a signal hander. So stop using ftp and use nc instead. This fixes test
failures of t_mtudisc on some environments such as my development machine
(amd64) and anita on sparc64.
The common functions store socks of rump_servers, interfaces of rump_servers
and buses that intefaces connect and allow to destroy them with common
functions without specifying which socks, interfaces and buses we should
destroy.
This change reduces lots of similar setup/cleanup codes.
Introduce net_common.sh that is to share common functions used in tests
for networking. This commit commonizes extract_new_packets. Other duplicate
codes will be moved to the file in further commits.
