Earlier versions of FreeBSD don't support ACLs.
Note that the ACL support code in archive_entry is standalone code and
unaffected by this. (In particular, it should be possible to
manipulate archives containing ACLs even if the ACLs cannot be
restored on the current system.)
* Re-use a single buffer for shar output formatting rather
than hammering the heap. (archive_write_set_format_shar.c)
* Fix a handful of minor memory leaks and clean up some of the
memory-management code.
try to set ACLs even if fflag restore fails, first cut at reading
Solaris tar ACLs
Code improvement: merge gnu tar read support into main tar reader;
this eliminates a lot of duplicate code and generalizes the tar
reader to handle formats with GNU-like extensions.
Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
from archive_entry (this makes archive_entry more format-agnostic)
Thanks to: David Magda for providing Solaris tar test files
mode (where the forked thread is the one and only thread and
is marked as system scope), set the system scope flag before
initializing the signal mask. This prevents trying to use
internal locks that haven't yet been initialized.

* ACL storage is no longer erased before a group of entries are added.
* ACL text creation no longer tries to skip over non-existent text.
* UTF8 encoder no longer blows up on invalid wide characters.
* Fixed ACL state management for default ACLs.
Also, publicize function for obtaining text-format ACL in various

that allows you to select a variant format.

bit more work needed in this area.
Added 'write_open_fd' and 'read_open_fd' to simplify, e.g.,
tar's u and r modes. Eliminated old 'write_open_file_position'
as a bad idea. (It required closing/reopening files to
do updates, which led to unpleasant implications.)

case where an /etc/nsswitch.conf file was present, but could not
be opened (e.g. due to permissions). Previously, the open failure
condition was suppressed, and the built-in defaults were used. In
revision 1.11, however, propagated the open failure causing all
nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs
including getpwnam and gethostbyname unconditionally failed.
This commit restores the previous behavior.

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

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.
