[PATCH 0/3] Various gssd fixes including machine-credential issue.

[Neil Brown <neilb@suse.de>]

As you probably know, since 3.7 (I think) Linux NFS has explicitly
asked for machine credentials for certain requests rather than asking
for root credentials as is previously did.
This causes a regression for people who don't have any machine
credentials configured and use "gssd -n".

I gather this was discussed on the mailing list earlier this year but
not resolved.

I would like to re-awaken the issue and offer a resolution (which has
been tested and found effective by a customer).

Hence these three patches.  The first two are minor issues that I
stumbled over while trying to understand the problem and are not
critical but probably should be fixed.

The third addresses the above mentioned issue.  It introduces a
variable "machine_uses_root_credentials" which is similar to the
current "root_uses_machine_credentials".  It also adds a "-N" flag to
set this variable.

I'm not certain what the defaults should be.  For backward
compatibility it would be best if '-n' set the this new variable as
well as clearing the old one, but then I'm not sure what exactly -N
should do.

Comments welcome.

Thanks,
NeilBrown
