1e03bff7f2 In fts_build(), if we try to chdir and fail (e.g. due to lack of search
permission), try to continue in FTS_DONTCHDIR mode.  Of course this
won't work for long paths, but we can't descend more than one pathname
component beyond the directory anyway if we lack search permission.

Here is a transcript demonstrating the change, where oldls is ls(1)
linked with the old fts(3):

	das@VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
	das@VARK:~> oldls t
	a       b       c
	das@VARK:~> oldls -l t
	das@VARK:~> \ls t
	a       b       c
	das@VARK:~> \ls -l t
	ls: a: Permission denied
	ls: b: Permission denied

325d97d0d1 Set errno to EBADF on attempts to write to a stream that is not

The issue of whether this is the right errno for funopened streams is

no errno.

857b57eae1 Remove a trailing newline, to behave as documented in syslog(3):
"A trailing newline is added if none is present."

The code in syslogd, stderr, and console output always adds a newline
at the EOL.  However, the existing code never actually removed a
trailing newline, and apparently relied on syslogd to convert it
into a space character.  Thus, the existing newline was converted
to a trailing space at the EOL by syslogd, while stderr, and console
output resulted in an empty line.

99ca5b8804 The FTS_NOSTAT option is an optimisation that reduces the number
of stat(2) calls by keeping an eye of the number of links a directory
has. It assumes that each subdirectory will have a hard link to its
parent, to represent the ".." node, and stops calling stat(2) when
all links are accounted for in a given directory.

This assumption is really only valid for UNIX-like filesystems: A
concrete example is NTFS. The NTFS "i-node" does contain a link
count, but most/all directories have a link count between 0 and 2
inclusive. The end result is that find on an NTFS volume won't
actually traverse the entire hierarchy of the directories passed
to it. (Those with a link count of two are not traversed at all)

The fix checks the "UFSness" of the filesystem before enabling the
optimisation.

1cc11684ac MFdragonfly: resolver fix for timeouts on unqualified hostnames
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.

8074e24dce The previous commit changed the behavior of nsdispatch() in the
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.

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.

59fac1825f On 4.X it was possible for an application to initialise a local FILE

locking was introduced into libc.

This change makes most (relevant) stdio functions work again when the
_extra file in FILE isn't initialised (and can't be without a libc
function to do it since the __sFILEX structure is private to libc).

settles on it being OK.

of the fixes were NULL where ascii <nul> ('\0') was needed, and a

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.

7b7e350998 Merge vfprintf.c, v1.61 and 1.62. For compatibility with __hdtoa()
and to reduce diffs between vfprintf.c and vfwprintf.c, declare xdigs*
to be char arrays rather than wchar_t arrays.

307649e2f3 Use 'uint32_t' instead of 'long' when a 32-bit integer is intended.
This results in no functional change, aside from fixing a data
corruption bug on LP64 platforms.  The code here could still use a
significant amount of cleanup.
