52828c0e9c In preparation for a new malloc implementation:
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.

09c00166e4 Make tv_sec a time_t on all platforms but alpha. Brings us more in line with
POSIX.  This also makes the struct correct we ever implement an i386-time64
architecture.  Not that we need too.

0eb88f2029 Implement ELF symbol versioning using GNU semantics. This code aims
to be compatible with symbol versioning support as implemented by
GNU libc and documented by http://people.redhat.com/~drepper/symbol-versioning
and LSB 3.0.

Implement dlvsym() function to allow lookups for a specific version of
a given symbol.

757686b115 Make our ELF64 type definitions match standards. In particular this
means:
o  Remove Elf64_Quarter,
o  Redefine Elf64_Half to be 16-bit,
o  Redefine Elf64_Word to be 32-bit,
o  Add Elf64_Xword and Elf64_Sxword for 64-bit entities,
o  Use Elf_Size in MI code to abstract the difference between
   Elf32_Word and Elf64_Word.
o  Add Elf_Ssize as the signed counterpart of Elf_Size.

4d5fe96d68 Fix a bug in dlinfo(RTLD_DI_SERINFOSIZE) requests. For each search path
we included the length of the path in the returned size but not the length
of the associated Dl_serpath structure.  Without this fix, programs
attempting to allocate a structure to hold the search path information
would allocate too small of a buffer and rtld would overrun the buffer
while filling it via a subsequent RTLD_DI_SERINFO request.

3b4399f6a7 Clean out the leftovers from the i386_set_gsbase() TLS conversion.
Like on libthr, there is an i386_set_gsbase() stub implementation here
to avoid libc.so.5 issues.  This should likely be a weak symbol and I
expect this will be fixed soon.

method of executing commands remotely.  There are no rexec clients in
the FreeBSD tree, and the client function rexec(3) is present only in
libcompat.  It has been documented as "obsolete" since 4.3BSD, and its
use has been discouraged in the man page for over 10 years.

d4337d869f Fix the load64 and store64 macros, created to handle 8-byte unaligned
loads and stores (resp.) The ldq_u and stq_u instruction mask off the
lower 3 bits of the final address before loading from or storing to
the address, so as to avoid unaligned loads and stores. They do not
themselves allow loads from or stores to unaligned addresses. Replace
the macro definitions by a packed struct dereference.

0fcbbd7bea When PAM support was added to rexecd in revision 1.29 (just prior to
5.0-RELEASE), a visually elusive bug was introduced.  A comparison
operator was changed to assignment.  As a result, rexecd behaved
always as if the `-i' option had been specified.  It would allow root
logins.  This commit corrects the situation in the obvious way.

A separate bug was introduced at the same time.  The PAM library
functions are called between the invocation of getpwnam(3) and the use
of the returned static object.  Since many PAM library functions
result in additional getpwnam(3) calls, the contents of the returned
static object could be changed from under rexecd.  With this commit,
getpwnam_r(3) is used instead.

Other PAM-using applications should be reviewed for similar errors in
getpw* usage.

Security:	rexecd's documented default policy of disallowing root
		logins was not enforced.

8fe7df9b68 If "dangerous" environment variables (LD_PRELOAD, LD_LIBMAP,
LD_LIBMAP_DISABLE, LD_LIBRARY_PATH) are used, then make sure the
libraries being loaded aren't on a noexec-mounted filesystem.

This is a compromise position: I'm assuming that nobody will be silly
enough to set the noexec mount flag on part of the default library
path, in order to avoid adding extra overhead into the common case
(where those environment variables aren't used).
