This splits the logic in the old parse_chap() function into a part that
parses the -iscsi options into the new driver-specific options, and
another part that actually applies those options (called apply_chap()
now).
Note that this means that username and password specified with -iscsi
only take effect when a URL is provided. This is intentional, -iscsi is
a legacy interface only supported for compatibility, new users should
use the proper driver-specific options.

Isn't more natural to let the local option take precedence over the global one?

I think this added password-secret is not the one looked up in
iscsi_parse_iscsi_option(), which is from -iscsi
(block/iscsi-opts.c:qemu_iscsi_opts). Is this intended? Or does it belong to a
different patch?

One would think so, but that's how the option work today, so we can't
change it without breaking compatibility. We can only newly define the
precedence of the new driver-specific options vs. the existing ones, and
there the local driver-specific ones do take precedence.

It is the one that it put into the QDict by iscsi_parse_iscsi_option(),
which is supposed to be the value from -iscsi.
Why do you think it's not the one? Maybe I'm missing something.

This was previously only available with -iscsi. Again, after this patch,
the -iscsi option only takes effect if an URL is given. New users are

This was previously only available with -iscsi. Again, after this patch,
the -iscsi option only takes effect if an URL is given. New users are
supposed to use the new driver-specific option.
All -iscsi options have a corresponding driver-specific option for the
iscsi block driver now.
