*printf() and *scanf(). Currently, this reduces the size of libc.so
by 9K on i386. But the real savings are for static binaries that use
*printf() or *scanf() but not strtod(); with an FP-disabled libc,
these binaries will not depend on the gdtoa routines, making each
binary about 22K smaller.
floating-point support, remove default definition of FLOATING_POINT
from the source, and change the compile-time option to
NO_FLOATING_POINT.
- Remove the HEXFLOAT option. It saves an insignificant amount of
space (<0.1% of the size of libc on i386) and complicates vfprintf()
and checkfmt().
-U flag to bsdtar. Essentially, this option breaks existing hard
links. According to SUSv2, tar is supposed to overwrite existing
files on extract by default which, in particular, preserves
existing hard links. Note that this is yet another bug in gtar; it
appears to always break existing links. (Maybe gtar's -U is broken?)
I'm unsure about how to handle this for other file types; the current
code always unlinks first unless the NO_OVERWRITE flag is specified.
I've commented this issue liberally and will come back to it later.
archive formats supported by libarchive, with some information about
the relative strengths and weaknesses of each format and notes about
issues with libarchive's support for those formats.
This page should make it unnecessary to list all of the libarchive
formats in the manpage of each program that uses libarchive.
Such programs can simply refer to libarchive-formats(5).
* little-endian old-style binary cpio archives
* big-endian old-style binary cpio archives
* SVR4 portable archives without CRC
* SVR4 portable archives with CRC
Note that I don't yet verify the CRC for the last one, and I'm
not quite certain I'm correctly parsing device numbers.
MS-CHAPv1 MPPE-keys).
- Added rad_demangle_mppe_key() for demangling mppe-keys (needed
for MPPE-keys).
- Added some typecasts for avoiding compiler warnings.
- Fix: better handle wrong usage of the lib (if the programmer
has not called rad_create_request() but rad_put_*(), then a
weird error message was returned).
- Added a new function for putting the Message-Authenticator.
- Verify the Message-Authenticator, if it was found inside a
response packet and silently drop the packet, if the validation
failed.
- Implicitly put the Message-Authenticator, if the EAP-Message
attribute was added.
- Added some missing defines.

The new fflags support in archive_entry supports Linux and FreeBSD
file flags and is a bit more gracious about unrecognized flag names
than strtofflags(3). This involves some minor API breakage.
The default tar format ("restricted pax") now enables pax extensions
when archiving files that have flags. In particular, copying dir
heirarchies with 'bsdtar cf - -C src . | bsdtar xpf - -C dest' now
preserves file flags. (Note the "p" on extract!)
While I'm here, fill in some additional explanation in the
archive_entry.3 manpage, fill in some missing MLINKS, mark some
overlooked internal functions 'static', and make a few minor style
fixes.
namespaces are visible. Previously, math.h failed to hide some C99-,
XSI-, and BSD-specific symbols in certain compilation environments.
The referenced PR has a nice listing of the appropriate conditions for
making symbols visible in math.h. The only non-stylistic difference
between the patch in the PR and this commit is that I superfluously
test for __BSD_VISIBLE in a few places to be more explicit about which
symbols have historically been part of the FreeBSD environment.

makeing sure the spinlock isn't already in use might be a nice feature to
have in theory, it's hard to implement in practice since the passed in
pointer may not be NULL, but still be an invalid value (i.e. 1..2..3.. etc).
The original might have pointers to user-specified strings;
copying the string (instead of just the pointer) protects against
the client re-using their own buffers.
I'm trying hard to avoid dumping all of the 'set' string functions
in favor of slower, but more predictable 'copy' semantics.

This fixes problems that occurred when using positional arguments in
format strings, particularly with more than STATIC_ARG_TBL_SIZE (8)
of them.

adjunct maps are used. One symtom of this bug is sshd saying:
login_get_lastlog: Cannot find account for uid X
when logging in. The problem here is caused by an incorrect reuse of the rv
variable when previous values are needed later.
High-resolution mtime/ctime/atime is not POSIX-standard, so hide
set/get of high-resolution time fields behind easily-mutable macros.
That makes it easier to change how those fields are accessed.
res_search only incremented got_servfail for h_errno == TRY_AGAIN *AND*
hp->rcode == SERVFAIL. However, there are cases such as timeouts where
rcode is not always set to SERVFAIL. This leads to inconsistent nameserver
operation during multi-domain and truncated dot searches, especially during
booting when portions of the network are being brought up simultanious with
dns lookups.
This patch attempts to correct the problem by unconditionally terminating
the search if TRY_AGAIN is returned (after res_query has gone through all
retries and name servers) instead of trying other domain elements in the
domain seach path.
This patch should fix reported problems (which I can reproduce) with some
NFS mounts failing during boot. This occured because mount_nfs thought the
host name lookup returned a definitive failure using a non-dotted host name
when, in fact, it timed out on the first part (host.search.domain.name) and
got a definitive host-not-found response on the second part (host.).
Generally speaking, search path name server timeouts can exceed 60 seconds
per element and most machines which consistently timeout on earlier portions
of a search path are effectively non-operational due to the imposed delays.
It is more important for DNS lookups to return the proper error code then
to be able to recover a valid lookup in later portions of the search path
in these situations.

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)
