3726033348 Fix Yet Another 16 byte stack alignment bug. Thankfully, this one is
solved by a simple 'make world'.  The signalcontext function was going
to the trouble of generating an even 16 byte alignment, but in fact it
needed to be odd aligned to simulate the 8-byte return address having
been pushed by the caller.  This fixes yet another group of crashes in
applications using libpthread.  And yet again, it was my fault all along.

While here, rename the duplicate internal ctx_wrapper() functions to
makectx_wrapper() and sigctx_wrapper() so that traces aren't ambiguous.

a03fd3b656 When a dynamic NSS module is built and linked against a thread
library, it may pull in that thread library at run time.  If the
process started out single-threaded, this could cause attempts to
release locks that do not exist.  Guard against this possibility by
checking __isthreaded before invoking thread primitives.

A similar problem remains if the process is linked against one thread
library, but the NSS module is linked against another.  This can only
be avoided by careful design of the NSS module.

44a3d34206 Many fixes:
* Disabled shared-library building, as some API breakage is
  still likely.  (I didn't realize it was turned on by default.)  If
  you have an existing /usr/lib/libarchive.so.2, I recommend deleting it.
* Pax interchange format now correctly stores and reads UTF8
  for extended attributes.  In particular, pax format can portably
  handle arbitrarily long pathnames containing arbitrary characters.
* Library compiles cleanly at -O2, -O3, and WARNS=6 on all
  FreeBSD-CURRENT platforms.
* Minor portability improvements inspired by Juergen Lock
  and Greg Lewis.  (Less reliance on stdint.h, isolating of
  various portability-challenged constructs.)
* archive_entry transparently converts multi-byte <-> wide character
  strings, allowing clients and format handlers to deal with either
  one, as appropriate.
* Support for reading 'L' and 'K' entries in standard tar archives
  for star compatibility.
* Recognize (but don't yet handle) ACL entries from Solaris tar.
* Pushed format-specific data for format readers down into
  format-specific storage and out of library-global storage.  This
  should make it easier to maintain individual formats without mucking
  with the core library management.
* Documentation updates to track the above changes.
* Updates to tar.5 to correct a few mistakes and add some additional
  information about GNU tar and Solaris tar formats.

Notes:
* The basic 'tar' reader is getting more general; there's not much
  point in keeping the 'gnutar' reader separate.  Merging the two
  would lose a bunch of duplicate code.
* The libc ACL support is looking increasingly inadequate for my needs
  here.  I might need to assemble some fairly significant code for
  parsing and building ACLs. <sigh>

Changes from the original patch include:
- Use d_addr_t rather than inventing a blkcnt type based on int64_t.
- Use strtoimax() rather than strtoull() to parse d_addr_t's from config
  files.
- Use intmax_t casts and %jd rather than %llu to printf d_addr_t values.

function to do it since the __sFILEX structure is private to libc).

cf5704e17b Recognize hardlinks when reading cpio files.
This doesn't yet address the issue of selective restore
of hardlinked files.  With cpio format, it's possible to correctly
restore any linked file; the API doesn't yet fully support this.
(There's no way for the library to inform a client whether or not
there's a file body associated with this entry.  The assumption
right now is that "hardlink" entries have no file body.)

a1f17de172 Minor API tweak: The format-specific write_header function now sets
the size in the archive_entry object to zero if that format doesn't
store a body for that file type.  This allows the client to determine
whether or not it should feed the file body to the archive.  In
particular, cpio stores the file body for hardlinks, tar and shar
don't.  With this change, bsdtar now correctly archives hardlinks in all
supported formats.

While I'm here, make shar output be more aggressive about creating directories.
Before this, commands such as:
    bsdtar -cv -F shar  some/explicit/path/to/a/file
wouldn't create the directory.  Some simple logic to remember the last
directory creation helps reduce unnecessary mkdirs here.

At this point, I think the only flaw in libarchive's cpio support is
the failure to recognize hardlinks when reading.

f9efe8694a Add a clean_environment call to libutil.
This function removes all environment variables except
the ones listed on a "whitelist."

The function accepts two whitelist arguments.
If the first is NULL, a built-in default list will be
used.  This allows callers to get a variety of behaviors:
  * Default screening: provide NULL for both lists
  * Custom screening: provide a custom list for the first argument
  * Modified default screening: provide NULL for first arg,
     list of additional variables to preserve in the second arg

5c3a55dea7 Backed out rev.1.6 and subsequent copying of it (bogus addition of
-static to CFLAGS).  It just turned rev.1.5 into an obfuscated no-op.
As explained in the log for rev.1.5, testing should be done in the
host environment but there is a problem in cross-compilation environments.
As not explained in the log for rev.1.6, there was apparently a practical
problem with cross-compiling (makeworld should have set -static in
LDFLAGS but apparently didn't).  Cross-compilation was especially
complicated because the relevant programs are test programs that were
run at beforeinstall time -- dynamic libraries might or might not exist
depending on the build options.  The complications became moot in
rev.1.8 when beforeinstall was renamed "test".

33dee81933 Make the resolver(3) and many associated interfaces much more reentrant.
The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now
with what should be totally reentrant, and h_errno values will now
be preserved correctly, but this does not affect interfaces such as
gethostbyname(3) which are still mostly non-reentrant.

In all of these relevant functions, the thread-safety has been pushed
down as far as it seems possible right now.  This means that operations
that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected
still under global locks that getaddrinfo(3) defines, but where possible
the locking is greatly reduced.  The most noticeable improvement is
that multiple DNS lookups can now be run at the same time, and this
shows major improvement in performance of DNS-lookup threaded programs,
and solves the "Mozilla tab serialization" problem.

No single-threaded applications need to be recompiled.  Multi-threaded
applications that reference "_res" to change resolver(3) options will
need to be recompiled, and ones which reference "h_errno" will also
if they desire the correct h_errno values.  If the applications already
understood that _res and h_errno were not thread-safe and had their own
locking, they will see no performance improvement but will not
actually break in any way.

Please note that when NSS modules are used, or when nsdispatch(3)
defaults to adding any lookups of its own to the individual libc
_nsdispatch() calls, those MUST be reentrant as well.

2710e4d1ef Initial import of libarchive.
What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.

bd224d495e Change libkse back to libpthread and make it the default
thread library for i386, amd64, and ia64.  For alpha
and sparc64 the library is not changed and remains libkse,
and links are installed so that libpthread -> libc_r.

The gcc -pthread option will be changed in a separate
commit so that it links to -lpthread instead of -lc_r.

1baa64733c I update the rwlock code in libthr to be more standards compliant and
what do I get for my troubles? libc breaks offcourse!

Reimplement a hack (in libthr) that allows libc to use
rwlocks without initializing them first. The hack was reimplemented
so that only a private libc version of the rwlock locking functions
initializes an uninitialized rwlock. The application version will
correctly fail.

98a11db62d When suspending a thread if the timeout was very short or
the system call got interrupted and the absolute timeout is
converted to a relative timeout, it may happen that we get a
negative number. In such a case, simply set the timeout to
zero so that if the event that the thread wants to wait for has
happened it can still return successfully, but if it hasn't
happened then the thread doesn't suspend indefinitely. This should
fix certain applications (including mozilla) that seem to hang
indefinitely sometimes.

94635227fd Fix an uninitialized variable bug that caused write_pmbr() to bogusly
return an error value that made Write_Disk() abort.  While on the
subject, improve the initialization of the error variable in read_gpt()
and update_gpt() even though nothing was broken there.

d15ff41778 - Added three new interfaces, NgAllocRecvMsg(), NgAllocRecvAsciiMsg(),
and NgAllocRecvData(), that dynamically allocate buffer for a binary
  message, an ascii message, and a data packet, respectively.  The size
  of the allocated buffer is equal to the socket's receive buffer size
  to guarantee that a message or a data packet is not truncated.

- Get rid of the static size buffer in NgSendAsciiMsg().
