Jeff Layton worked on this patch set with me.
patch 0001 and 0002 clean up process_krb5_upcall() by moving the two cases into
helper functions.
patch 0003 is the heart of this patch set.
commit f9cac65972da588d5218236de60a7be11247a8aa added the fork to
process_krb5_upcall so that the child assumes the uid of the principal
requesting service. This is good for the reasons listed in the commit.
When machine credentials are used, a gssd_k5_kt_princ entry is added to
a global list and used by future upcalls to note when valid machine credentials
have been obtained. When a child process performs this task, the entry to the
global list is lost upon exit, and all upcalls for machine credentials re-fetch
a TGT, even when a valid TGT is in the machine kerberos credential cache.
Since forking is not necessary when the principal has uid=0, solve the
gssd_k5_kt_princ_list issue by only forking when the uid != 0.
Please do more testing. Comments welcome.
