selftests: forwarding: lib: Move here vlan_capture_{, un}install()

2018-06-01T18:11:01+00:00

Move vlan_capture_install() and vlan_capture_uninstall() from
mirror_vlan.sh test to lib.sh so that it can be reused in other tests.

selftests: forwarding: lib: Extract trap_{, un}install()

2018-05-25T02:26:19+00:00

A mirror-to-vlan test that's coming next needs to install the trap
unconditionally. Therefore extract from slow_path_trap_{,un}install()
a more generic functions trap_install() and trap_uninstall(), and covert
the former two to conditional wrappers around these.

selftests: forwarding: Use sysctl_set(), sysctl_restore()

2018-05-03T17:37:02+00:00

Instead of hand-managing the sysctl set and restore, use the wrappers
sysctl_set() and sysctl_restore() to do the bookkeeping automatically.

selftests: forwarding: lib: Add sysctl_set(), sysctl_restore()

2018-05-03T17:37:02+00:00

Add two helper functions: sysctl_set() to change the value of a given
sysctl setting, and sysctl_restore() to change it back to what it was.

selftests: forwarding: Allow running specific tests

2018-05-03T16:54:31+00:00

Similar to commit a511858c7536 ("selftests: fib_tests: Allow user to run
a specific test"), allow user to run only a subset of the tests using
the TESTS environment variable.

This is useful when not all the tests can pass on a given system.

Example:
# export TESTS="ping_ipv4 ping_ipv6"
# ./bridge_vlan_aware.sh
TEST: ping					[PASS]
TEST: ping6					[PASS]

selftests: forwarding: Add libs for gretap mirror testing

2018-04-27T18:57:49+00:00

To simplify implementation of mirror-to-gretap tests, extend lib.sh with
several new functions that might potentially be useful more
broadly (although right now the mirroring tests will be the only
client).

Also add mirror_lib.sh with code useful for mirroring tests,
mirror_gre_lib.sh with code specifically useful for mirror-to-gretap
tests, and mirror_gre_topo.sh that primes a given test with a good
baseline topology that the test can then tweak to its liking.

selftests: forwarding: Allow creation of interfaces without a config file

2018-03-12T02:44:24+00:00

Some users want to be able to run the tests without a configuration file
which is useful when one needs to test both virtual and physical
interfaces on the same machine.

Move the defines that set the type of interface to create and whether to
create it away from the optional configuration file to the library like
the rest of the defines.

selftests: forwarding: Exit with error when missing interfaces

2018-03-12T02:44:24+00:00

Returning 0 gives a false sense of success when the required modules did
not even manage to be initialized and register the required net devices.

selftests: forwarding: Exit with error when missing dependencies

2018-03-12T02:44:24+00:00

We already return an error when some dependencies (e.g., 'jq') are
missing so lets be consistent and do that for all.
