8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

8e60fa95cb libc/rpc: replace comma with semicolon when pertinent.
Uses of commas instead of a semicolons can easily go undetected. The comma
can serve as a statement separator but this shouldn't be abused when
statements are meant to be standalone.

Detected with devel/coccinelle following a hint from DragonFlyBSD.

5eff94ee56 RPC: populate local address for rendezvous transporter.
When accepting a connection on underlying tcp socket rpc vc
transporter fails to populate local address.  This change rectifies
this problem by modifying rendezvous_request() to fill out the xptr
structure member with appropriate information.

e2c83f74f4 Fix a bug in the userland rpc library, where it would use a
negative return value from write to update its position in
a buffer. The patch, courtesy of Andrey Simonenko, also simplifies
a conditional by removing the "i != cnt" clause, since it is
always true at this point in the code. The bug caused problems
for mountd, when it generated a large reply to an exports RPC
request.

ecc03b80f1 Don't call xdrrec_skiprecord in the non-blocking case. If
__xdrrec_getrec has returned TRUE, then we have a complete request in
the buffer - calling xdrrec_skiprecord is not necessary. In particular,
if there is another record already buffered on the stream,
xdrrec_skiprecord will discard both this request and the next
one, causing the call to xdr_callmsg to fail and the stream to be
closed.

aee2eba2d1 If AF_LOCAL is used, we need to use __msgread_withcred() instead of
just read() in non-blocking mode too. The reason is obvious. NetBSD
uses a complete different way to get the credentials so this patch
only applies to FreeBSD.

08760d5a57 Fix the credential handling code.
In NetBSD, Solaris, xprt->xp_p2 pointed directly to the credentials,
in FreeBSD xprt->xp_verf.oa_base was a pointer to a struct cmessage,
which is defined as follow:

struct cmessage {
        struct cmsghdr cmsg;
        struct cmsgcred cmcred;
};

The credentials were submitted the right way and xprt->xp_p2 pointed to them.
But cb_verf.oa_flavor was still empty. There was an assignment missing
in svc_recv() in svc_vc.c:

msg->rm_call.cb_verf.oa_flavor = AUTH_UNIX;

Also

+       if (addr.ss_family == AF_LOCAL) {
+               xprt->xp_raddr = *(struct sockaddr_in *)xprt->xp_rtaddr.buf;
+               xprt->xp_addrlen = sizeof (struct sockaddr_in);
+       }

was missing. But the first seems not to be needed:

I guess in rpc.yppasswdd there was a typo:

- transp>xp_verf.oa_flavor != AUTH_UNIX) {
+ rqstp->rq_cred.oa_flavor != AUTH_UNIX) {

This little fix does fix the breakage in rpc.yppasswdd :-)

+       if (msg.msg_controllen == 0 ||
+           (msg.msg_flags & MSG_CTRUNC) != 0)
+               return (-1);

We cannot set the cb_verf.oa_length in svc_recv() of svc_vc.c,
the credentials get overwritten then, and that's bad.

2bc21ed985 Hopefully improve control message passing over Unix domain sockets.
1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.

2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.

3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.

4) You can now send SCM_TIMESTAMP messages.

5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).

This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).

6) Fix userland programs to use CMSG_* macros too.

7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

8360efbd6c Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.
