d352c94070 If somebody does an execv("foo", NULL) (which theoretically is an error),
avoid crashing inside rtld (since it's easy) since everything else handles
it.  Of course, if the target program checks argv[], it'll fall over.

df68fc891e Add an 'al' (autologin username) capability to getty/gettytab. This is a
damn useful thing for using with serial consoles in clusters etc or secure
console locations.  Using a custom gettytab entry for console with
an entry like 'al=root' means that there is *always* a root login ready on
the console.  This should replace hacks like those which go with conserver
etc.  (This is a loaded gun, watch out for those feet!)

ae5a3098bc Ignore empty usernames, and repeat the login: prompt in this case.
There's not much point in having uucpd behave differently than
login(1) for this, and now uucpd is compatible to the default chat
script of Taylor UUCP which sends a single \r at first.

While i was at it, added a few strategic ``errno = 0;''s, so at least
an `Undefined error 0' will be returned for things like a closed
connection while reading the login ID or password, as opposed to an
even more bogus thing like `No such file or directory'.

b811a3806f As previously threatened, clean up the rshd -a option and make it default
on rshd and rlogind.  However, note that:
1: rshd used to drop a connection with -a if the hostname != ip address.
   This is unneeded, because iruserok() does it's own checking.
   It was also wrong if .rhosts had an explicit IP address in it,
   connections would be dropped from that host solely because the DNS was
   mismatched even though it was explicitly intended to work by IP address.
2: rlogind and rshd check the hostname mappings by default now because that
   is what goes into the utmp/wtmp and logs.  If the hostname != ip address,
   then it uses the IP address for logging/utmp/wtmp purposes.  There isn't
   much point logging ficticious hostnames.
3: rshd -a is now accepted (but ignored) for compatability.  If you really
   want to make life miserable for people with bad reverse DNS, use tcpd in
   paranoid mode (which is questionable anyway, given DNS ttl tweaking).

65a1e124be Fix a bug in the handling of minor version numbers. Formerly, the
rtld would accept the first shared library it found with the right
major version number, even if the minor version number was too low.
If a different version of the shared library with an adequate minor
version number appeared later in the search path, it would not be
found.

Now the rtld searches all locations first looking for a library
with a minor version that is high enough.  Only if such a library
is not found will it fall back to accepting a minor version number
that is too low.  As before, a warning comes out in that case.

This solves some problems encountered when building an older world
on a -current system.

7bf4199b5f Fix a bug that showed up when debugging dynamically linked programs.
References from GDB to "printf" and various other functions would
find the versions in the dynamic linker itself, rather than the
versions in the program's libc.  This fix moves the GDB link map
entry for the dynamic linker to the end of the search list, where
its symbols will be found only if they are not found anywhere else.
It was suggested by Doug Rabson, though I implemented it a little
differently.

I personally would prefer to leave the dynamic linker's entry out
of the GDB search list altogether.  But Doug argues that it is
handy there for such things as setting breakpoints on dlopen().
So it stays for now, at least.

Note, if we ever integrate the dynamic linker with libc (which has
several important benefits to recommend it), this whole problem
goes away.

2b7c06f6c8 Don't recognize a file as an a.out shared library unless it has at
least 2 version numbers.  This fixes the bug where the dynamic
linker would try to load an ELF shared library if it found one.

Note, this change also fixes the same thing in "ld", because the
code is shared.

For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name.  I haven't decided what, if anything, to
do about that.

6c76bd6d54 Implement ldconfig functionality for ELF. The hints are stored in
a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints".
These hints consist only of the directory search path.  There is
no hash table as in the a.out hints, because ELF doesn't have to
search for the file with the highest minor version number.  (It
doesn't have minor version numbers at all.)

A single run of ldconfig updates either the a.out hints or the ELF
hints, but not both.  The set of hints to process is selected in
the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout"
or "-elf" command line option.  The rationale is that you probably
want to search different directories for ELF than for a.out.

"ldconfig -r" is faked up to produce output like we are used to,
except that for ELF there are no minor version numbers.  This should
enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports
even for ELF.

I implemented the ELF functionality in a new source file, with an
eye toward eliminating the a.out code entirely at some point in
the future.

446517db81 Since I got no objections to this patch, and no one has offered any
alternative, I present .. ta! da! .. the __error() hack.

This patch to the a.out dynamic loader provides old a.out binaries
with __error() if they are linked with an older libc that lacks it,
but are also linked against a library that needs it.

There is a smaller, tricker hack that takes advantage of the fact
that ld.so has __error() too, courtesy of the new libc, but this
hack is the straightforward version.
