393d77ffad Bitch more loudly when someone botches changes to kinfo_proc
in the hopes that they will actually *read* the comment above
it and *follow* the instructions so as to cause all the rest
of us less a lot less grief.

5641ae5dc3 - Don't hold the proc lock across VREF and the fd* functions to avoid lock
order reversals.
- Add some preliminary locking in the !RF_PROC case.
- Protect p_estcpu with sched_lock.

f227364a17 - Release Giant a bit earlier on syscall exit.

  needed.

c65c565b44 Proc locking. Lock around psignal() and also ensure both an exclusive
proctree lock and the process lock are held when updating p_pptr and
p_oppid.  When we are just reaading p_pptr we only need the proc lock and
not a proctree lock as well.

628d2653d6 - Proc locking. Most of signal handling is now MP safe and doesn't require
Giant.  The only exception is the CANSIGNAL() macro.  Unlocking the proc
  lock around sendsig() in trapsignal() is also questionable.  Note that
  the functions sigexit(), psignal(), and issignal() must be called with
  the proc lock of the process in question held.  postsig() and
  trapsignal() should not be called with the proc lock held, but they
  also do not require Giant anymore either.
- Remove spl's that are now no longer needed as they are fully replaced.

1b43703b47 - Add an extra check in priority_propagation() for UP systems to ensure we
don't end up back at ourselves which would indicate deadlock.
- Add the proc lock to the witness dup_list as we may hold more than one
  process lock at a time.
- Don't assert a mutex is owned in _mtx_unlock_sleep() as that is too late.
  We do the checks in the macros instead.

6451855f6d - Use _PHOLD and move it before a PROC_UNLOCK to reduce the number of
mutex operations in kthread_create().
- Lock a kthread's proc before changing its parent via proc_reparent().
- Test P_KTHREAD not P_SYSTEM in kthread_suspend() and kthread_resume().
  P_SYSTEM just means that the process shouldn't be swapped and is used
  for vinum's daemon for example.
- Lock all the signal state used for suspending and resuming kthreads with
  the proc lock.

57934cd3c8 - Lock the forklist with an sx lock.
- Add proc locking to fork1().  Always lock the child procoess (new
  process) first when both processes need to be locked at the same
  time.
- Remove unneeded spl()'s as the data they protected is now locked.
- Ensure that the proctree is exclusively locked and the new process is
  locked when setting up the parent process pointer.
- Lock the check for P_KTHREAD in p_flag in fork_exit().

2aa33d2f1e Check to see if p_fd is NULL before derferencing it in checkdirs(). It's
possible for us to see a process in the early stages of fork before p_fd
has been initialized.  Ideally, we wouldn't stick a process on the allproc
list until it was fully created however.

c65437a326 - Call proc_reparent() when handing a process off to init in exit rather
than dinking around in the process lists explicitly.
- Hold both the proctree lock and proc lock of the child process when
  reparenting a process via proc_reparent.
- Lock processes while sending them signals.
- Miscellaenous proc locking.
- proc_reparent() now asserts that the child is locked in addition to an
  exclusive proctree lock.

c4a21abf00 - Include <sys/systm.h> for KASSERT().
- Move the _mtx_assert() prototype up to the top of the file with the rest
  of the function prototypes.
- Define all the mtx_foo() macros in terms of mtx_foo_flags().
- Add a KASSERT() to check for invalid options in mtx_lock_flags().
- Move the mtx_assert() to ensure a mutex is owned before releasing it
  in front of WITNESS_EXIT() in all the mtx_unlock_* macros.
- Change the MPASS* macros to be on #ifdef INVARIANTS, not just #ifdef
  MUTEX_DEBUG since most of them check to see that the mutex functions are
  called properly.  Define MPASS4() in terms of KASSERT() to do this.
- Define MPASS{,[23]} in terms of MPASS4() to simplify things and avoid
  code duplication.

0db10dac4b - In the locking key for struct proc, generalize the '+' symbol to mean
that write access to a member requires both locks and read access only
  requires one of the given locks.  Convert instances of '(c+)' to
  '(c + k)' as a result.
- Change p_pptr from (e) to (c + e).
- Change p_oppid from (c) to (c + e).
- Change p_args from (b?) to (c + k).
- Move the actual work of STOPEVENT, PHOLD, and PRELE to _STOPEVENT,
  _PHOLD, and _PRELE.  The new macros do not acquire the proc lock and
  simply assert that it is held.  The non _ prefixed macros acquire the
  proc lock and then call the _ prefixed macros.
- Add a PROC_LOCK_NOSWITCH() macro to be used when releasing the proc lock
  while already holding a spin lock (usually sched_lock).
- Add a PROC_LOCK_ASSERT() macro to be used to make assertions about the
  proc lock.  It takes the usual mtx_assert() macro arguments as its
  second argument.

7331c2a252 In order to avoid recursing on the backing mutex for sx locks in the
INVARIANTS case, define the actual KASSERT() in _SX_ASSERT_[SX]LOCKED
macros that are used in the sx code itself and convert the
SX_ASSERT_[SX]LOCKED macros to simple wrappers that grab the mutex for the
duration of the check.

5293465fef o Introduce filesystem-independent POSIX.1e ACL utility routines to
support implementations of ACLs in file systems.  Introduce the
  following new functions:

      vaccess_acl_posix1e()          vaccess() that accepts an ACL
      acl_posix1e_mode_to_perm()     Convert mode bits to ACL rights
      acl_posix1e_mode_to_entry()    Build ACL entry from mode/uid/gid
      acl_posix1e_perms_to_mode()    Generate file mode from ACL
      acl_posix1e_check()            Syntax verification for ACL

  These functions allow a file system to rely on central ACL evaluation
  and syntax checking, as well as providing useful utilities to
  allow ACL-based file systems to generate mode/owner/etc information
  to return via VOP_GETATTR(), and to support file systems that split
  their ACL information over their existing inode storage (mode, uid,
  gid) and extended ACL into extended attributes (additional users,
  groups, ACL mask).

o Add prototypes for exported functions to sys/acl.h, sys/vnode.h
