a39a98c45d Implement rquota RPC version 2, compatible with the linux implementation, 
as proposed on tech-userlevel on Dec 06 2002. This allows to retrieve
group quota informations from NFS servers.

1075c8325b Apply DoS fix as described by Crist J. Clark <crist.clark@attbi.com> 
on <security@freebsd.org>, and subsequently in FreeBSD's cvs repository
as libexec/ftpd/ftpd.c rev 1.133:

	The FTP daemon was vulnerable to a DoS where an attacker could bind()
	up port 20 for an extended period of time and thus lock out all other
	users from establishing PORT data connections. Don't hold on to the
	bind() while we loop around waiting to see if we can make our
	connection.

32adf030a4 ftpd was unable to service the pwd request once you entered a directory 
without search permission. This confused some ftp clients.

We fix this problem by maitaining a cached path when getcwd() does not work.
The symbolic links and ../ are resolved in the cached path, and it is finnally
checked for accuracy by comparing ./ and the cached path with stat (device
and inode comparison). If the comparison fails, pwd fails as it did before,
and if the comparison succeeds, the cached path is displayed.

If paths are too long, we should just compare ./ with a truncated path and
fail, thus making pwd displaying an error as it did before.

7a48cdb883 As seen on tech-userlevel... 
There are several optimizations here:

1) Objects on _rtld_list_main do not participate in the DAG structures
   at all.  This is okay because all symbols must be resolvable at
   link/load time, and _rtld_list_main is always searched first, so
   any references from those objects must necessarily be resolved to
   other objects on _rtld_list_main.

   (Making this work completely required setting obj->main a bit
   earlier; hence the RTLD_MAIN hack.)

2) Objects on _rtld_list_main are not put on _rtld_list_global,
   preventing an extra search.

3) A bit is used to keep track of whether an object is on
   _rtld_list_global, so we don't have to do a silly linear search.

4) A small attempt is made to prevent objects being put on the DAG
   lists multiple times (using a silly linear search).

The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.

Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.

09a0767aa9 Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and 
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.

The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

This is done by decoupling where a shlib is installed from how it
is located.  Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only.  SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.

The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.

a3c903f7cb Resolve the GOT before doing relocations. Then, when doing relocations, for 
symbols in the global part of the symbol table, use the updated GOT entry
rather than doing a lookup.  (This provides the same effect as `-z combreloc'
on other platforms -- at most one lookup is done per symbol.)

Unfortunately, it is necessary to turn off lazy binding on MIPS.  As the
comment says:

                         * XXX DANGER WILL ROBINSON!
                         * You might think this is stupid, as it intentionally
                         * defeats lazy binding -- and you'd be right.
                         * Unfortunately, for lazy binding to work right, we
                         * need to a way to force the GOT slots used for
                         * function pointers to be resolved immediately.  This
                         * is supposed to be done automatically by the linker,
                         * by not outputting a PLT slot and setting st_value
                         * to 0, but GNU ld does not do so reliably.

d1351c627c Um, a little bit of sanity here: 
l_addr is always supposed to be obj->relocbase -- or so says the GDB code that
uses it.  So, set it to this on all platforms.  It already was on VAX
explicitly, and on everything else except MIPS implicitly (because
mapbase==relocbase for all existing shlibs).  For some silly/stupid reason, a
new field was created that the MIPS GDB currently uses.
Another MD #ifdef bites it.

86103e2f0e Several small changes that shave 7-8% off the simple-exec-loop test: 
* Rename _rtld_find_library() to _rtld_load_library().  It now calls
  _rtld_load_object() if necessary to actually load the object, rather
  than having the caller do it.  To do this, it also takes the `mode'
  argument that gets passed to _rtld_load_object().

* On a related note, remove _rtld_check_library(), and instead call
  _rtld_load_object() to instead try actually loading the object.  We
  save two extra namei's and a bunch of redundant work (almost
  literally the same code) this way.

* In _rtld_map_object(), mmap(2) the first page read-only, rather than
  read(2)ing it.

* In _rtld_symlook_obj(), compare the *second* character of the symbol
  name before calling strcmp().  (This first character is too
  frequently `_', and turns out to not be helpful, in libc.)

* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
  -- this also allows removing the `in_plt' argument to
  _rtld_symlook_list() and _rtld_symlook_obj().

Also:

* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
  the each object, instead use obj->mapsize as the upper bound.

89b1e287f7 find_user() in process.c does an unbounded copy into a destination 
buffer that is smaller in size than the source buffer.

also, there is no guarantee that any of the string components of
the request packet are null terminated.

in some cases, not all elements of the response buffer are
explicitly set. specifically pad and addr. a talk client can spy to
see which host is talking to which host by sending out regular
packets, to which talkd responds without clearing the addr element.

38a05c7450 Use LOGIN_NAME_MAX instead of `10' for the size of the curname[] buffer. 
Allows /etc/ftpchroot to work correctly for usernames > 9 characters.

3cc5ae01bc Correct somewhere where, in rev 1.3, two new sentences had been dropped 
into the middle of an existing sentence, and put them after it instead.

735f9f38c0 Split the `self' case out of _rtld_relocate_nonplt_objects, into a new function 
_rtld_relocate_nonplt_self(), which is called from _rtld_start.
Now we're completely relocated before main() is called.
We also no longer need _GOT_END_, so junk the ld script.

This code assumes that ld.elf_so only contains RELATIVE relocs, but that's
supposed to be the case for -Bsymbolic anyway.

5d2f386289 Add a switch for easy enabling of single-byte 8-bit output. 
This is somewhat of a hack, but I find it better than having
to run env(1) from inetd(8), or changing the environment for
inetd(8) itself (and thus all daemons started by it).
