After VPP-635 was merged, did one more pass. While the code was waiting
to be merged, a few changes were merged to master with the same issue.
This is a few additional changes addressing the same issue. See VPP-635.

In the CLI parsing, below is a common pattern:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;
while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
{
if (unformat (line_input, "x"))
x = 1;
:
else
return clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
}
unformat_free (line_input);
The 'else' returns if an unknown string is encountered. There a memory
leak because the 'unformat_free(line_input)' is not called. There is a
large number of instances of this pattern.
Replaced the previous pattern with:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;
while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
{
if (unformat (line_input, "x"))
x = 1;
:
else
{
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
goto done:
}
}
/* ...Remaining code... */
done:
unformat_free (line_input);
return error;
}
In multiple files, 'unformat_free (line_input);' was never called, so
there was a memory leak whether an invalid string was entered or not.
Also, there were multiple instance where:
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
used 'input' as the last parameter instead of 'line_input'. The result
is that output did not contain the substring in error, instead just an
empty string. Fixed all of those as well.
There are a lot of file, and very mind numbing work, so tried to keep
it to a pattern to avoid mistakes.
