11663004bd When restoring a directory, allow symlinks to be followed. The full
logic here gets a little complex, but the net effect is that the
SECURE_SYMLINKS flag will prevent us from ever following a symlink.
Without it, we'll only follow symlinks to dirs.  bsdtar specifies
SECURE_SYMLINKS by default, suppresses it for -P.

I've also beefed up the write_disk_secure test to verify this
behavior.

32364a7ddb MfP4: set/unset tracking for atime, ctime, mtime, and size fields.
This generalizes the existing set/unset tracking for hardlink/symlink
fields and extends it to cover non-string fields.  Eventually, this
will be further extended to cover most fields.

In particular, this is needed to correctly detect when time fields
are missing (for example, reading ustar archives doesn't set atime or
ctime) for proper time restore and is helpful when trying to determine
whether to overwrite data when restoring hardlinks.

This commit updates the tests but not the docs.

d6742bfbd3 Add thread-specific caching for small size classes, based on magazines.
This caching allows for completely lock-free allocation/deallocation in the
steady state, at the expense of likely increased memory use and
fragmentation.

Reduce the default number of arenas to 2*ncpus, since thread-specific
caching typically reduces arena contention.

Modify size class spacing to include ranges of 2^n-spaced, quantum-spaced,
cacheline-spaced, and subpage-spaced size classes.  The advantages are:
fewer size classes, reduced false cacheline sharing, and reduced internal
fragmentation for allocations that are slightly over 512, 1024, etc.

Increase RUN_MAX_SMALL, in order to limit fragmentation for the
subpage-spaced size classes.

Add a size-->bin lookup table for small sizes to simplify translating sizes
to size classes.  Include a hard-coded constant table that is used unless
custom size class spacing is specified at run time.

Add the ability to disable tiny size classes at compile time via
MALLOC_TINY.

bc093719ca Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:

- Improved driver model:

  The old TTY layer has a driver model that is not abstract enough to
  make it friendly to use. A good example is the output path, where the
  device drivers directly access the output buffers. This means that an
  in-kernel PPP implementation must always convert network buffers into
  TTY buffers.

  If a PPP implementation would be built on top of the new TTY layer
  (still needs a hooks layer, though), it would allow the PPP
  implementation to directly hand the data to the TTY driver.

- Improved hotplugging:

  With the old TTY layer, it isn't entirely safe to destroy TTY's from
  the system. This implementation has a two-step destructing design,
  where the driver first abandons the TTY. After all threads have left
  the TTY, the TTY layer calls a routine in the driver, which can be
  used to free resources (unit numbers, etc).

  The pts(4) driver also implements this feature, which means
  posix_openpt() will now return PTY's that are created on the fly.

- Improved performance:

  One of the major improvements is the per-TTY mutex, which is expected
  to improve scalability when compared to the old Giant locking.
  Another change is the unbuffered copying to userspace, which is both
  used on TTY device nodes and PTY masters.

Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

136600fe59 Change bpf(4) to use the cdevpriv API.
Right now the bpf(4) driver uses the cloning API to generate /dev/bpf%u.
When an application such as tcpdump needs a BPF, it opens /dev/bpf0,
/dev/bpf1, etc. until it opens the first available device node. We used
this approach, because our devfs implementation didn't allow
per-descriptor data.

Now that we can, make it use devfs_get_cdevpriv() to obtain the private
data. To remain compatible with the existing implementation, add a
symlink from /dev/bpf0 to /dev/bpf. I've already changed libpcap to
compile with HAVE_CLONING_BPF, which makes it use /dev/bpf. There may be
other applications in the base system (dhclient) that use the loop to
obtain a valid bpf.

ad5e21e24b Use cpack() and the gcc extension __imag__ to implement cimag() and
conj() instead of using expressions like z * I. The latter is bad for
several reasons:

1. It is implemented using arithmetic, which is unnecessary, and can
   generate floating point exceptions, contrary to the requirements on
   these functions.

2. gcc implements complex multiplication using a formula that breaks
   down for infinities, e.g., it gives INFINITY * I == nan + inf I.

1192a80ed1 On i386, gcc truncates long double constants to double precision
at compile time regardless of the dynamic precision, and there's
no way to disable this misfeature at compile time. Hence, it's
impossible to generate the appropriate tables of constants for the
long double inverse trig functions in a straightforward way on i386;
this change hacks around the problem by encoding the underlying bits
in the table.

Note that these functions won't pass the regression test on i386,
even with the FPU set to extended precision, because the regression
test is similarly damaged by gcc. However, the tests all pass when
compiled with a modified version of gcc.

3522c38bbe Detect if the application has cleared the environ variable by setting
the first value (environ[0]) to NULL.  This is in addition to the
current detection of environ being replaced, which includes being set to
NULL.  Without this fix, the environment is not truly wiped, but appears
to be by getenv() until an *env() call is made to alter the enviroment.

This change is necessary to support those applications that use this
method for clearing environ such as Dovecot and Postfix.  Applications
such as Sendmail and the base system's env replace environ (already
detected).  While neither of these methods are defined by SUSv3, it is
best to support them due to historic reasons and in lieu of a clean,
defined method.

Add extra units tests for clearing environ using four different methods:
1. Set environ to NULL pointer.
2. Set environ[0] to NULL pointer.
3. Set environ to calloc()'d NULL-terminated array.
4. Set environ to static NULL-terminated array.

8862f666ad Fix some problems with asinf(), acosf(), atanf(), and atan2f():
- Adjust several constants for float precision. Some thresholds
  that were appropriate for double precision were never changed
  when these routines were converted to float precision. This
  has an impact on performance but not accuracy. (Submitted by bde.)

- Reduce the degrees of the polynomials used. A smaller degree
  suffices for float precision.

- In asinf(), use double arithmetic in part of the calculation to
  avoid a corner case and some complicated arithmetic involving a
  division and some buggy constants. This improves performance and
  accuracy.

Max error (ulps):
         asinf  acosf  atanf
before   0.925  0.782  0.852
after    0.743  0.804  0.852

As bde points out, it's cheaper for asin*() and acos*() to use
polynomials instead of rational functions, but that's a task for
another day.

e5abb5e698 Begin de-spaghettifying the code that handles positional arguments.
In particular, encapsulate the state of the type table in a struct,
and add inline functions to initialize, free, and manipulate that
state. This replaces some ugly macros that made proper error handling
impossible.

While here, remove an unneeded test for NULL and a variable that is
initialized (many times!) but never used. The compiler didn't catch
these because of rampant use of the same variable to mean different
things in different places.

This commit should not cause any changes in functionality.

4110421449 We should also save and restore the MXCSR as on amd64, but detecting

64c2e46650 Two FP-related setjmp/longjmp changes:
1. Save and restore the control part of the MXCSR in addition to the
   i387 control word to ensure that the two are consistent.

   Note that standards don't require longjmp to restore either control
   word, and none of Linux, MacOS X 10.3 and earlier, NetBSD, OpenBSD,
   or Solaris do it. However, it is historical FreeBSD behavior, and
   bde points out that it is needed to make longjmping out of a signal
   handler work properly, given the way FreeBSD clobbers the FPU state
   on signal handler entry.

2. Don't clobber the FPU exception flags in longjmp. C99 requires them
   to remain unchanged.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

7de1ecef2d Add two commands to _umtx_op system call to allow a simple mutex to be
locked and unlocked completely in userland. by locking and unlocking mutex
in userland, it reduces the total time a mutex is locked by a thread,
in some application code, a mutex only protects a small piece of code, the
code's execution time is less than a simple system call, if a lock contention
happens, however in current implemenation, the lock holder has to extend its
locking time and enter kernel to unlock it, the change avoids this disadvantage,
it first sets mutex to free state and then enters kernel and wake one waiter
up. This improves performance dramatically in some sysbench mutex tests.

c605eea952 Turn execvpe() into an internal libc routine.
Adding exevpe() has caused some ports to break. Even though execvpe() is
a useful routine, it does not conform to any standards.

This patch is a little bit different from the patch sent to the mailing
list. I forgot to remove execvpe from the Symbol.map (which does not
seem to miscompile libc, though).

80a6a0328a Refactor one of the ISO extraction tests: Move the reference
file into a separate file (instead of embedding it in the C code)
and use later timestamps (timestamps too close to the Epoch fail
predictably on systems that lack timegm(), whose mktime() doesn't
support dates before the Epoch and which are running in timezones
with negative offsets from GMT).  The goal here is to test the ISO
extraction, not the local platform's time support.

e3580e9d91 Don't export the unused __use_pts() routine.
The __use_pts() routine was once probably used by libutil to determine
if we are using BSD or UNIX98 style PTY device names. It doesn't seem to
be used outside grantpt.c, which means we can make it static and remove
it from the Symbol.map.
