From: Owen Hilyard <ohilyard@iol.unh.edu>

Fixes for a few memory leaks in the cmdline_autotest unit test.

All of the leaks were related to not freeing the commandline struct
after testing had completed.

Fixes: dbb860e03e ("cmdline: tests")

Hi Owen,

Thanks for fixing this test.
Some comments below.

This last cmdline_free() is not needed, because the test is (cl == NULL)

I would keep an empty line here, to highlight that the comment
only refers to cmdline_stdin_exit().

In this function test_cmdline_fns(), there is the same scheme than in
test_cmdline_socket_fns(), so I think you should apply the same kind
of modifications (even if a non-NULL return value should not happen):


   -	if (cmdline_new(NULL, prompt, 0, 0) != NULL)
   +	cl = cmdline_new(NULL, prompt, 0, 0);
   +	if (cl != NULL)

Maybe the 2 tested error cases that are expected to return NULL
should go before the correct one, so that it's not needed to have
another cl pointer variable.

The cmdline_free(cl) after a if (cl == NULL) is not needed.

After that change, you can add my ack in v4.

I took the liberty of doing the change when applying and added your ack.

It looks like an update to my IDE turn back on converting tabs to spaces on
save. Sorry about that.

From: Owen Hilyard <ohilyard@iol.unh.edu>

[ upstream commit ca7204b921c2f328ab1222772af40922970e7c4b ]

Fixes for a few memory leaks in the cmdline_autotest unit test.

All of the leaks were related to not freeing the commandline struct
after testing had completed.

Fixes: dbb860e03e ("cmdline: tests")
