b57f9be4b7 Revert part of the last commit, remove {g|s}etflags from the libc
interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.

Additionally there were complications with the build/install-world
process.  It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.

There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).

It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

9742b65930 sync iruserok() extension API with other BSDs
Some of rcmd related function is need to be updated to
  support IPv6. Some of them are already updated as standard
  document. But there is also several de-facto functions and
  they are not listed in standard documents.
  They are,

    iruserok()  (used by rlogind, rshd)
    ruserok()   (used by kerberos, etc)

  KAME package updated those functions in original way.

    iruserok_af()
    ruserok_af()

  But recently there was discussion on IETF IPng mailing
  list about how to sync those API, and it is decided,

    -Those function is not standard and not documented.
    -But let BSDs sync their API as de-facto.

  And after some discussion, it is announced that

    -add update to iruserok() as iruserok_sa()
    -no ruserok() API change(it is only updated internaly)

So I sync those API before 4.0 is released.
The changes are,
   -prototype changes
   -ruserok() internal update (use iruserok_sa() inside)
   -removal of ruserok_af()
   -change iruserok_af() as static functioin, and also prefix the name with __.
   -add iruserok_sa() (Just call __iruserok_af() inside)
   -adding flag AI_ALL to getipnodebyaddr() called from __icheckhost().
    This is necessary to support IPv4 communication via AF_INET6 socket
    could be correctly authenticated via iruserok_sa()
   -irusreok_af() call is replaced to iruserok_sa() call
    in rlogind, and rshd.

4bff590782 When a threads package registers locking methods with dllockinit(),
figure out which shared object(s) contain the the locking methods
and fully bind those objects as if they had been loaded with
LD_BIND_NOW=1.  The goal is to keep the locking methods from
requiring any lazy binding.  Otherwise infinite recursion occurs
in _rtld_bind.

This fixes the infinite recursion problem in the linuxthreads port.

4baa442de2 Revamp the mechanism for enumerating and calling shared objects'
init and fini functions.  Now the code is very careful to hold no
locks when calling these functions.  Thus the dynamic linker cannot
be re-entered with a lock already held.

Remove the tolerance for recursive locking that I added in revision
1.2 of dllockinit.c.  Recursive locking shouldn't happen any more.

Mozilla and JDK users: I'd appreciate confirmation that things still
work right (or at least the same) with these changes.

363b7bd537 Work around an assert failure in the dynamic linker's default thread
locking functions.  If an application loads a shared object with
dlopen() and the shared object has an init function which requires
lazy binding, then _rtld_bind is called when the thread is already
inside the dynamic linker.  This leads to a recursive acquisition
of the lock, which I was not expecting -- hence the assert failure.

This work-around makes the default locking functions handle recursive
locking.  It is NOT the correct fix -- that should be implemented
at the generic locking level rather than in the default locking
functions.  I will implement the correct fix in a future commit.

Since the dllockinit() interface will likely need to change, warn
about that in both the man page and the header file.

52ec4df9e8 Add a new function dllockinit() for registering thread locking
functions to be used by the dynamic linker.  This can be called by
threads packages at start-up time.  I will add the call to libc_r
soon.

Also add a default locking method that is used up until dllockinit()
is called.  The default method works by blocking SIGVTALRM, SIGPROF,
and SIGALRM in critical sections.  It is based on the observation
that most user-space threads packages implement thread preemption
with one of these signals (usually SIGVTALRM).

The dynamic linker has never been reentrant, but it became less
reentrant in revision 1.34 of "src/libexec/rtld-elf/rtld.c".
Starting with that revision, multiple threads each doing lazy
binding could interfere with each other.  The usual symptom was
that a symbol was falsely reported as undefined at start-up time.
It was rare but not unseen.  This commit fixes it.

happened as it was working around problems elsewhere (ie: binutils/ld
not doing the right thing according to the ELF design).  libcrypt has
been adjusted to not need the runtime -lmd.  It's still not quite right
(ld is supposed to work damnit) but at least it doesn't impact all the

c0f970ba23 Make jdk-1.1.8 work again. It turns out that some code inside
libjava peeks into the dynamic linker's private Obj_Entry structures.
My recent changes introduced some new members near the front of
the structures, causing libjava to get the wrong fields.  This commit
moves the new members toward the end of the structure so that the
layout of the portion that is relevant to JDK remains the same as
before.

I will work with the JDK porting team to see if we can come up with
a less fragile way for them to do what they need to do.  I understand
the current approach was necessary in order to work around some
limitations of the dynamic linker.  Maybe it's not necessary any
more.

4382ccec34 Revamp the symbol lookup algorithm to cope better with objects
loaded separately by dlopen that have global symbols with identical
names.  Viewing each dlopened object as a DAG which is linked by its
DT_NEEDED entries in the dynamic table, the search order is as
follows:

  * If the referencing object was linked with -Bsymbolic, search it
    internally.
  * Search all dlopened DAGs containing the referencing object.
  * Search all objects loaded at program start up.
  * Search all objects which were dlopened() using the RTLD_GLOBAL
    flag (which is now supported too).

The search terminates as soon as a strong definition is found.
Lacking that, the first weak definition is used.

These rules match those of Solaris, as best I could determine them
from its vague manual pages and the results of experiments I performed.

2be78ea16b Fix a serious performance bug for large programs on the Alpha,
discovered by Hidetoshi Shimokawa.  Large programs need multiple
GOTs.  The lazy binding stub in the PLT can be reached from any of
these GOTs, but the dynamic linker only has enough information to
fix up the first GOT entry.  Thus calls through the other GOTs went
through the time-consuming lazy binding process on every call.

This fix rewrites the PLT entries themselves to bypass the lazy
binding.

Tested by Hidetoshi Shimokawa and Steve Price.

do it.  Note, this change is not enabled and it might never be

dynamic linker as an executable should make it start up faster,
because it won't have any relocations.  But in practice I suspect
the difference is negligible.

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.

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.

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.

bc60c8025e ELF preparation step 2:
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.

This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.

We are getting close to an ELF make world, but I'll let this
all settle for a week or two...

66c1e653c8 Back out "always UTC" fix since some people want visually identical 'ls'
output for local users. FTP protocol RFC also says that 'ls' output is
not machine-readable. "always UTC" still possible with TZ= in ftpd
environment by price of having UTC in log files too.

9ab1a03565 Do TZ= as first thing, since FTP protocol is unable to tell zone offset in
any case.

It makes no difference for anon account (since chroot already makes it GMT),
but if you do mirror with special non-anon login, in old variant
your mirror will be wholy retransmitted twice in the year due to
time zone changes (/etc/localtime plays bad role here)
