6210388a93 Make emacs work again. This is a workaround for the fact that the
emacs a.out file, self-generated by emacs's "unexec" function in
"unexsunos4.c", is invalid.  In particular, its "_end" symbol has
the wrong value.  The dynamic linker was using the value of that
symbol to initialize its sbrk break level.

The workaround is to peek at the executable's a.out header in
memory, and calculate what "_end" should be based on the segment
sizes.

I will work out a fix for emacs and send it to the FSF.  This
dynamic linker workaround is still worthwhile, if only to avoid
forcing all emacs users to build a new version.

Note: xemacs gives a bogus warning at startup, for related reasons.
The warning is harmless and can safely be ignored.  I will send a
patch to the xemacs maintainers to get rid of it, and meanwhile
add a patch file to our port.

08bdd3d27d Get rid of the dynamic linker's internal malloc package, and arrange
things so that it uses the same malloc as is used by the program
being executed.  This has several advantages, the big one being
that you can now debug core dumps from dynamically linked programs
and get useful information out of them.  Until now, that didn't
work.  The internal malloc package placed the tables describing
the loaded shared libraries in a mapped region of high memory that
was not written to core files.  Thus the debugger had no way of
determining what was loaded where in memory.  Now that the dynamic
linker uses the application's malloc package (normally, but not
necessarily, the system malloc), its tables end up in the regular
heap area where they will be included in core dumps.  The debugger
now works very well indeed, thank you very much.

Also ...

Bring the program a little closer to conformance with style(9).
There is still a long way to go.

Add minimal const correctness changes to get rid of compiler warnings
caused by the recent const changes in <dlfcn.h> and <link.h>.

Improve performance by eliminating redundant calculations of symbols'
hash values.

f05011e686 PR: bin/771 and bin/1037 are resolved by this change
This change changes the default handling of linemode so that older and/or
stupider telnet clients can still get wakeup characters like <ESC> and
<CTRL>D to work correctly multiple times on the same line, as in csh
"set filec" operations.   It also causes CR and LF characters to be read by
apps in certain terminal modes consistently, as opposed to returning
CR sometimes and LF sometimes, which broke existing apps.  The change
was shown to fix the problem demonstrated in the FreeBSD telnet client,
along with the telnet client in Solaris, SCO, Windows '95 & NT, DEC OSF,
NCSA, and others.

A similar change will be incorporated in the crypto version of telnetd.

This resolves bin/771 and bin/1037.

23677e98fe Putting records with zero-length keys into a Berkeley DB hash database
is asking for trouble (sequential database enumerations can get caught
in an infinite loop). The yp_mkdb(8) utility avoids putting such records
into a database, but ypxfr does not. Today I got bit by a NULL entry in
one of the amd maps on my network, which is served by a SunOS master.
The map was transfered successfully to my FreeBSD slave, but attempting
to dump it with ypcat(1) caused ypserv(8) to transmit the same record
over and over again, making the map appear to be infinitely large. I
finally noticed the problem while testing a new version of amd under
development at the Columbia CS department, which began gobbling up insane
amounts of memory while trying to swallow the map.

To deal with this problem, I'm modifying ypxfr to watch for records
with zero-length keys and turn them into something less destructive
before writing them to the database.

d030d2d2ae Many places in the code NULL is used in integer context, where
plain 0 should be used.  This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

9453d60b10 Fixed `make depend' and related bogons. LDFLAGS was used for
ld-specific flags.  LDFLAGS is really for ld-related flags for cc,
not for ld, and some flags, e.g., -Bshareable, mean completely
different things to cc and ld.  Having the wrong things in LDFLAGS
also broke the standard ${PROG} target.  This was kludged around
by using a special rule that depended on LDFLAGS being bogus.
Fixing `make depend' broke the special rule but fixed the standard
rule (except in the DESTDIR case, which was handled more strictly
here than elsewhere).

2 (RTLD_NOW).  I will add defines of these symbols to <dlfcn.h> as soon
as I've done a little more checking to make sure they won't cause
collisions or bootstrapping problems that would break "make world".

The "LD_*" environment variables which alter dynamic linker behavior are
now treated as unset if they are set to the empty string.  This agrees
with the standard SVR4 conventions for the dynamic linker.

Add a work-around for programs compiled with certain buggy versions of
crt0.o.  The buggy versions failed to set the "crt_ldso" member of the
interface structure.  This caused certain error messages from the
dynamic linker to begin with "(null)" instead of the pathname of the
dynamic linker.

ab6c6377b3 If errors occur during the loading of the shared libraries required by
the main program, report them directly from the dynamic linker and die
there, rather than returning an error message to crt0.o.  This enables
the printing of error messages even for old executables, whose version
of crt0.o is not able to print them.

This fix closes PR bin/1869.

The code in crt0.o for printing error messages from the dynamic linker
is no longer used, because of this change.  But it must remain, for
backward compatibility with older dynamic linkers.

5584286a91 Update to handle new version ld.so.hints and info in executable for
configurable fallback search paths, as well as new crt interface version.

Also:
 - even faster getenv(), get all environment variable settings in a single
   pass.
 - ldd printf-like format specifications
 - minor code cleanups, one vsprintf -> vsnprintf (harmless)

The library search sequence is a little more complete now. Before,
it'd search $LD_LIBRARY_PATH (by opendir/readdir/closedir), then read
the hints file, then read /usr/lib (again by scanning thr directory).  It
would then fail if there was no "found" library.

Now, it does LD_LIBRARY_PATH and the hints file the same, but then uses
a longer fallback path.  The -R path is fetched from the executable if
specified at build time, the ldconfig path is appended, and /usr/lib is
appended to that. Duplicates are suppressed.  This means that simply
placing a new library in /usr/local/lib will work (the same as it did in
/usr/lib) without needing ldconfig -m.  It will find it quicker if the
ldconfig is run though.

Similar changes have been made to the NetBSD ld.so, but ours is rather
different now due to John Polstra's speedups and fixes from a while back.

The ldd printf-like format support came direct from NetBSD.

b186571cf6 Update the backends to go with the top-level ld changes. The non-i386
changes are for completeness, I don't think they work.  There are changes
to deal with the new include files.

d0a184df5d Support for .weak (in addition to the N_INDR stab) for gcc/g++. Also deal
with the -R option and store the path in the dynamic header when specified.
The $LD_RUN_PATH environment variable is not checked yet.

While here, split up the code a bit more to enable more selective replacing
of GPL'ed components that are linked with ld.so with others.

Obtained from: NetBSD (mostly, the breakup is my fault)

	Add -s flag to tftpd.  This enables the so-called secure mode
of tftpd where it chroots to a given directory before allowing access
to the files.  In addition, it runs as nobody when in this mode.
Reviewed a long time ago by Bill and Garrett.  Apply my patch from the

eaa86f9d7f Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6.  Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

87d0dcafca Use `install -C' instead of lots of shell commands to install ld.so
as atomically as possible.

(Immutable targets can't be renamed without opening a window when
neither the source nor the target is immutable.  Perhaps there
should be a rename_immutable syscall to do this if unsetting the
immutable flags would work.)

680b396b51 Removed unused `-I.'s from CFLAGS.
"." means the object directory, so it is just confusing to use it
when nothing is included from the object directory unless the object
directory is also the source directory.  It is confusing for "."
not to mean the source directory anyway, so used `-I.'s should be
replaced by `-I${.OBJDIR}'.
