76183f3453 Introduce a version field to `struct xucred' in place of one of the
spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being).  Accordingly, change users of
xucred to set and check this field as appropriate.  In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former.  This also has the pleasant sideaffect of removing some
duplicate code.

9a0b3389d5 This patch cleans up the ident stuff in inetd. The code which has
been patched so many times it was a bit of a mess. There are style,
code and man page cleanups. The following are the functional changes:

	The RFC only permits the returning of 4 possible error
	codes, make sure we only return these (PR 27636).

	Use MAXLOGNAME to determine the longest usernames.

	Add a -i flag, which returns the uid instead of the username
	(this is from a PR 25787, which also contained alot of the
	cleanups in this patch).

d0847e9377 Make dg_echo return up to the first 65536 bytes of a datagram.
The patch I used isn't quite the one Lars suggested, but the size
of the largest datagram you can recv isn't #defined anywhere, and
probably isn't even bounded for some protocols.

c0511d3b58 Switch to using a struct xucred instead of a struct xucred when not
actually in the kernel.  This structure is a different size than
what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there.  As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).

This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size.  This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

6fe761c783 Security fix: correctly set groups according to the user. Previously,
root's groups' permissions were being used, so a user could read up to
16 (excluding initial whitespace) bytes of e.g. a wheel-accessible file.

Also, don't allow blocking on the opening of ~/.fakeid, so replace a fopen()
with open() and fdopen().  I knew I'd be going to hell for using C file
streams instead of POSIX syscalls...

1078172a77 Fix a 64-bit'ism in the handling of the ident service. sysctlbyname() takes
a size_t as its 3rd argument, which is 64-bits on the alpha.  The 'len'
variable used was a int, which is only 32-bits.  Use size_t as the type
for 'len' to work-around this.

18338e9e0f Implement -g and -d options in my ident code. The -g flag uses a random
garbage value for the username (hex garbage, that is), and the -d flag
provides a default username for fallback purposes if the user cannot be
looked up.  That is very useful for the case where inetd auth is
running on a NAT box.

While I'm here updating the manpage, clean up an English error and a
few small nits.

6f426a27c5 Style nits:
* Bring memory allocation failure handling in line with that of
	the rest of the code.
      * Nestle block curlies between case statements correctly.

I've left the in-block declarations alone, since style(9) says we should
conform to the existing style within the code, and inetd already does
this. I've left the asprintf()'s in there because that's how Brian wants
it.
