[LTP] [PATCH v5 0/3] networking/stress/icmp: add ip xfrm ipsec support

[Hangbin Liu]

As we know, most of the network stress tests have IPsec testing, and we use
setkey for configuration. But setkey[1] hasn't updated for a long time. And
some distros, RHEL7 for example, even don't have ipset-tools package. On
other hand, iproute2 is recommend for network configuration. And ip xfrm is
more powerful than setkey. So let's use ip xfrm for ipsec testing.

[1] http://ipsec-tools.sourceforge.net/

Change from V4:
1. minimise icmp-uni-basic, remove some useless comment.
2. use tst_exit instead of exit 0
3. Fix max message size and add comment in network_stress.icmp to describe how
   we calculate them.
4. fix some typo
TODO: For icmp-uni-basic test, we test each message size to make sure the
connectivity. In icmp-multi-diffip/nic test, we will do ping flood test with
multi ip/nic for stress testing since we have already make sure the connectivity.


Change from V3:
1. use message size array in tst_ping
2. add tst_ipsec_cleanup in ipsec_lib
3. use lhost/rhost naming in ipsec_lib
4. add icmp-uni-basic in the upper icmp directory
5. some other small fixs.

Change from V2:
1. remove c2x and use hexdump directly.
2. remove indent after "case".
3. remove useless export and old scripts like check_env.
4. remove tst_init_iface.
5. remove return value check after setup ipsec env.
6. remove addr config as Alexey said, we assume the address already added.

Change from V1:
1. update tst_ping() to use default iface and addr. make ping from local side.
2. remove unused variables. add -s option when use tst_rhost_run. Use ROD
   before normal commands.
3. change all "tst_resm TBROK && exit" to "tst_brkm TBROK"
3. still keep tst_init_iface in test icmp4-uni-basic01 because we will
   set_ipv4/6addr each time.

Hangbin Liu (3):
  lib/test_net.sh: add tst_ping() to check icmp connectivity
  network/stress: add ipsec lib
  network/stress/icmp: add icmp-uni-basic to implement all icmp basic
    stress test
