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.

adjunct maps are used.  One symtom of this bug is sshd saying:

16fc3635f7 Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

5c70dac879 Modify the implementation of libc semaphores so that they can be
overridden by the threads library to provide a userland version
of non-pshared semaphores and cancellation points.  Also add
a sem_timedwait().

The libc version of semaphores always uses kernel semaphores
regardless of whether pshared is set or not.  When threads are
not present, it is difficult to get sem_wait() or sem_timedwait()
to do the right thing (since pthread_cond_timedwait() and
pthread_cond_wait() are stubs in libc and just return immediately).

89a26fd1fc Add a kluge suggested by Marcel to paper over the difference between
gethostname()'s old and new signatures without requiring a library
bump.  Note that programs which called gethostname() with a negative
argument were already broken, since the same type conversion was done
by the old implementation.  Add a note in the Makefile so that whoever
next bumps the libc revision will delete the kluge at the same time
(as it will no longer be necessary).  This is only operative on 64-bit
platforms.

effcb5eca3 Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEM
when the buffer is not long enough to hold the current host name.
POSIX does not standardize error returns for gethostname(), so it
doesn't matter which one we use, but ENAMETOOLONG is at least a little
more intuitive, and mi suggests the existence of prior art.  I've been
running with this change for a while on my home machine with no
effect.  At the same time, I've updated the prototype for
gethostname() to use the correct standard type (size_t) for the
namelen argument.

All of the in-tree callers fall into one of the following categories:
1) Call perror() or equivalent when gethostname() fails.
2) Ignore gethostname()'s return value entirely, potentially resulting
in data corruption if the buffer is too small.
3) Fall back to a (possibly sensible) default value if gethostname()
fails.

Many of the callers I examined shows signs of confusion about the
correct sizing of the host name buffer.  gethostname(3) now has more
information about this, as well as updated standards information.

0287aa1cee Revert to using yp_order() to probe for master.paswd.by* maps and
don't probe the server at all for passwd.by* maps. This fixes
interoperability with the Services For UNIX NIS server (which is
really a front end to Captive^WActiveDirectory). This server
incorrectly returns success for all YPPROC_MASTER requests,
even for maps that don't exist, which makes it impossible to
(ab)use it to probe for the existence of the master.passwd.by*
maps.

This is a little kludgey, but basically restores the original
behavior of getpwent.c as it is in -stable, and works around both
the lack of YPPROC_ORDER on NIS+ servers as well as the broken
YPPROC_MASTER on Services For UNIX servers.

5460b1abd2 ``Strong typing is a crutch for people with weak memories.''
Correct a bug that should have wreaked havoc everywhere, but for
some reason only bit unlucky people who use `-march' optimizations.
The compiler cannot assist one in distinguishing between the two
function calls below.

   int nsdispatch(void *, ...);
   void *discard;

   nsdispatch(&discard, ...);  /* correct .. no, really! */
   nsdispatch(discard, ...);   /* Boom                   */

4c3c0fecae Don't use `memset' to initialize a struct passwd. A module
may not fill in all fields, and in the case of string fields, this could
cause trouble for applications.  (The only likely example is `pw_class',
because this field is not used by all modules in all cases.)

Move initialization of struct passwd from module-specific code to the
dispatch code.

05f98035ee = Implement thread-safe versions of the getpwent(3) and getgrent(3)
family of functions using the new nsdispatch(3) core.  Remove

= Re-implement the traditional getpwent(3)/getgrent(3) functions on

= Update the on-disk format of the hashed version of the passwd(5)
  databases to allow for versioned entries.  The legacy version is
  `3'.  (Don't ask.)

= Add support for version `4' entries in the passwd(5) database.
  Entries in this format are identical to version 3 entries except
  that all integers are stored as 32-bit integers in network byte
  order (big endian).

= pwd_mkdb is updated to generate both version 3 and version 4

  signal ERANGE-type issues.

o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based

464ef179a0 In cgetmatch(3), return -1 if a NULL or 0-length name parameter is used.
This situation most notably arises in chkprintcap, when a /etc/printcap
entry has an empty rp= attribute. In that case, cgetmatch would enter
an infinite loop if any entry in the file has multiple names.

This causes lpd to hang at boot time on 5.0-DP2 when both conditions
are met (:rp=: and multiple names -- not necessarily on the same entry).

f51c1e897d Rework the sysconf(3) interaction with aio:
sysconf.c:
  Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0'
  return value from the kernel sysctl.

vfs_aio.c:
  Make aio reset its configuration parameters to -1 after unloading
  instead of 0.

posix4_mib.c:
  Initialize the aio configuration parameters to -1
  to indicate that it is not loaded.
  Add a facility (p31b_iscfg()) to determine if a posix4 facility has been
  initialized to avoid having to re-order the SYSINITs.
  Use p31b_iscfg() to determine if aio has had a chance to run yet which
  is likely if it is compiled into the kernel and avoid spamming its
  values.
  Introduce a macro P31B_VALID() instead of doing the same comparison over
  and over.

posix4.h:
  Prototype p31b_iscfg().

subsystems capabilities:

_SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX
_SC_AIO_MAX returns the default _POSIX_AIO_MAX
_SC_AIO_PRIO_DELTA_MAX returns the default of 0

Without these adjustments the values returned are -1 even when the
aio side of the kernel returns '0' for them which is incorrect.

What happened here is that the module first registered its "ident"
with openlog(3), then PAM library unloaded module with dlclose(3),
and the next call to syslog(3) resulted in SIGSEGV.

Use the correct constants directly from sysconf() rather than calling
sysctl() to tell us the (still compiled-in) value.  Leave the CTL_POSIX1B
stuff alone for now (but I'd like to see this replaced with a single
structure returning all of the relevant information).

0d3bcc2e80 Make the threatened fts(3) ABI fix. FTSENT now avoids the use of the struct
hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI.  FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about.  As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use.  All callers in the
tree are updated to use the correct prototype.

Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.

5965373e69 - Introduce a new struct xvfsconf, the userland version of struct vfsconf.
- Make getvfsbyname() take a struct xvfsconf *.
- Convert several consumers of getvfsbyname() to use struct xvfsconf.
- Correct the getvfsbyname.3 manpage.
- Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the
  kernel, and rewrite getvfsbyname() to use this instead of the weird
  existing API.
- Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist
  sysctl.
- Convert a vfsload() call in nfsiod.c to kldload() and remove the useless
  vfsisloadable() and endvfsent() calls.
- Add a warning printf() in vfs_sysctl() to tell people they are using
  an old userland.

After these changes, it's possible to modify struct vfsconf without
breaking the binary compatibility.  Please note that these changes don't
break this compatibility either.

When bp will have updated mount_smbfs(8) with the patch I sent him, there
will be no more consumers of the {set,get,end}vfsent(), vfsisloadable()

It's silly to call sysctl() to get the value of _PATH_STDPATH from

the implementation.  (This is also part of my grand scheme to get
rid of sysctl's `user' category, which should never have been created.)
