Commit 428879dc91 adds a requirement for a new upcall for the
gssd(8). This patch adds that upcall.
Unfortunately, the old gssd.c would not build against the new
patched gssd.x.
This patch will fix the build.

This reverts commit c33509d49a.
It turns out that the long 27 second delay I saw in the
gss_acquire_cred() call was caused by a (mis)configured
DNS. Although I did not specify "dns" in /etc/nsswitch.conf,
I did have a /etc/resolv.conf file on the system (left
there by wpa_supplicant). As such, with no route, it was
somehow trying to contact the DNS server, although there was none.
Once I got rid of the /etc/resolv.conf file, it worked
as expected.
Since there is now a large 5 minute timeout on the
kernel to gssd(8) upcalls, the gssd(8) daemon will not
get terminated when this delay occurs and the only affect
is a 30 second delay during the mount.
Discussed with: bjk
If an NFS mount using "sec=krb5[ip],gssname=<name>" is
done, the gssd daemon fails. There is a long delay
(several seconds) in the gss_acquire_cred() call and then
it returns success, but the credentials returned are
junk.
I have no idea how long this has been broken, due to some
change in the Heimdal gssapi library call, but I suspect
it has been quite some time.
Anyhow, it turns out that replacing the "desired_name"
argument with GSS_C_NO_NAME fixes the problem.
Replacing the argument should not be a problem, since the
TGT for the host based initiator credential in the default
keytab file should be the only TGT in the gssd'd credential
cache (which is not the one for uid 0).
I will try and determine if FreeBSD13 and/or FreeBSD12
needs this same fix and will MFC if they need the fix.
This problem only affected Kerberized NFS mounts when the
"gssname" mount option was used. Other Kerberized NFS
mount cases already used GSS_C_NO_NAME and work ok.
A workaround if you do not have this patch is to do a
"kinit -k host/FQDN" as root on the machine, followed by
the Kerberized NFS mount without the "gssname" mount
option.

We've got some cases where the other end of gssd's AF_LOCAL socket gets
closed, resulting in an error (and SIGPIPE) when it tries to do I/O to it.
Closing without cleaning up means the next time nfsd starts up, it hangs,
unkillably; this allows gssd to handle that particular error.
* Limit the retry cound in gssd_syscall to 5.
The default is INT_MAX, which effectively means forever. And it's an
uninterruptable RPC call, so it will never stop.
The two changes mitigate the problem.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

When gssd exits it leaves the kernel state set by
gssd_syscall(). nfsd sees this and waits endlessly
in an unkillable state for gssd to come back. If you
had acidentally started gssd then stopped it, then
started nfsd you'd be in a bad way until you either
restarted gssd or rebooted the system. This change
fixes that by setting the kernel state to "" when
gssd exits.

This appears to be required for some non-FreeBSD servers to
get a kerberized NFS mount to work. Also, ignore some signals when daemonized,
which might fix the gssd from "disappearing" without leaving a core dump.
Given the tight timeframe for the FreeBSD9.2 release, I have
committed this while waiting for code review. I will commit
