[LTP] [PATCH 2/4] net: Allow to overwrite libraries getopts handlers

[Petr Vorel]

Network libraries recently started to use TST_OPTS and TST_PARSE_ARGS:
89a83d8a0 ("net/ipsec_lib.sh: Process getopts parameters with TST_OPTS
and TST_PARSE_ARGS")
ce920a5a4 "network/virt_lib.sh: Process getopts parameters with TST_OPTS
and TST_PARSE_ARGS"
5f088c3f4 ("nfs/nfs_lib.sh: Fix wrong getopts parameter handling")

This allows to test using these libs customize getopts.

[LTP] [PATCH 3/4] net: Allow to skip additional getopts

[Petr Vorel]

Network libraries which use tst_test.sh allow to avoid setting their
additional getopts. With TST_NET_SKIP_PARSE_ARGS=1 only -6 from
tst_net.sh is handled (for both new and legacy API) and -h and -i from
tst_test.sh (for new API only).

[LTP] [PATCH 4/4] net/macsec0{1, 2}.sh: Use TST_NET_SKIP_PARSE_ARGS=1

[Petr Vorel]

These tests load ipsec_lib.sh and virt_lib.sh.
Currently tst_net.sh doesn't support being used by more libraries, so
when handling getopts the later one wins.
Disabling variables as they aren't used in the runtest file.

Alexey, do you use library variables for debugging?
Or would you prefer to be without this and to have at least one
libraries getopts?


Kind regards,
Petr

Hi Petr,

Perhaps, we need a prefix TST_.

Shouldn't the same patch remove the setting of 'ipver' in the tests?

Thanks,
Alexey

So, to customize these options we would need to implement the original
library options as well or you are going to pass the rest of the options
to the library ipsec_lib_parse_args handler?

I think TST_OPTS should include the library ones and the new options
from the test.

It would be better to show the usage somewhere, i.e. when it is
really needed.

I'm for keeping the IPsec options in macsec test, some of them are not
explicitly defined in the test, therefore can be changed.

For virt_lib.sh library the better fix would be to define the options
only for vxlan/geneve tests, because only those tests are currently
using them.

Thanks for comments, both makes sense. I wanted to do it after migrating everything to new
API, but probably better to do it before.

OK, I'll include this one in patchset, which migrate virt_lib.sh + ipsec_lib.sh into the
new API. I tried to introduce some changes before as the whole patch is going to be quite
big (due other bugs and the need to migrate virt_lib.sh and ipsec_lib.sh altogether.

My idea is if the test which uses any of virt_lib.sh or ipsec_lib.sh needs to change
getopts, it's it's responsibility to add these getopts.


Kind regards,
Petr
