35f19cdc6c - Add a 'flags' parameter to VFS_ROOT(). This is intended to allow
lookup to do shared locks on the root.  Filesystems are free to ignore
   flags and instead acquire an exclusive lock if they do not support
   shared locks.

c167961e27 - If vput() is called with a shared lock it must upgrade to an exclusive
before it can call VOP_INACTIVE().  This must use the EXCLUPGRADE path
   because we may violate some lock order with another locked vnode if
   we drop and reacquire the lock.  If EXCLUPGRADE fails, we mark the
   vnode with VI_OWEINACT.  This case should be very rare.
 - Clear VI_OWEINACT in vinactive() and vbusy().
 - If VI_OWEINACT is set in vgone() do the VOP_INACTIVE call here as well.

3e6bcad375 - Remove some long dead LOOKUP_SHARED code that tracked the lock state.
- Always pass LOCKSHARED and rely on namei() to ignore it when
   LOOKUP_SHARED is not set.

ae88db8a72 - Remove the #ifdef LOOKUP_SHARED from some calls to NDINIT. The
LOCKSHARED flag is simply ignored in namei() if LOOKUP_SHARED is not
   enabled.

ad09e57f41 - Clear LOCKSHARED if LOOKUP_SHARED is not enabled. This is not strictly
necessary since we disable the shared locks in vfs_cache, but it is
   prefered that the option not leak out into filesystems when it is
   disabled.

fdd6a3ff3c - All of the bugs which lead to the complication of the LOOKUP_SHARED
config option have now been fixed.  All filesystems are properly locked
   and checked via DEBUG_VFS_LOCKS.  Remove the workaround code.

cae2d2c61f - The NFS client was incorrectly masking SIGSTOP (which is
non-maskable).
- The NFS client needs to guard against spurious wakeups
  while waiting for the response. ltrace causes the process
  under question to wakeup (possibly from ptrace()), which
  causes NFS to wakeup from tsleep without the response being
  delivered.

df8f908079 Restore queue depth settings across tag disable events. The system often
disables tag queuing temporarily in order to allow controllers a window
to safely perform transfer negotiation with non-compliant devices.  Before
this change, CAM would restore the queue depth to the controller specified
maximum or device quirk level rather than any depth determined by reactions
to QUEUE FULL/BUSY events or an explicit user setting.

During device probe, initialize the flags field for XPT_SCAN_BUS.
The uninitialized value often confused CAM into not bothering to
issue an AC_FOUND_DEVICE async event for new devices.  The reason
this bug wasn't reported earlier is that CAM manually announces
devices after the initial system bus scans.

a3e1ec194d Bounds check the user-supplied length used in a copyout() in
svr4_do_getmsg().  In principle this bug could disclose data from
kernel memory, but in practice, the SVR4 emulation layer is probably
not functional enough to cause the relevant code path to be executed.
In any case, the emulator has been disconnected from the build since
5.0-RELEASE.

8a4d2b06c7 Bounds check the length parameter to i386_set_ldt() before passing it

affects 6-CURRENT on or after 2005-01-26.

aa675b572f Reject packets larger than IP_MAXPACKET in linux_sendto() for sockets
with the IP_HDRINCL option set.  Without this change, a Linux process
with access to a raw socket could cause a kernel panic.  Raw sockets
must be created by root, and are generally not consigned to untrusted
applications; hence, the security implications of this bug are
minimal.  I believe this only affects 6-CURRENT on or after 2005-01-30.

f2c7668eb1 Make ps_nargvstr and ps_nenvstr unsigned. This fixes an input
validation error in procfs/linprocfs that can be exploited by local
users to cause a kernel panic.  All versions of FreeBSD with the patch
referenced in SA-04:17.procfs have this bug, but versions without that
patch have a more serious bug instead.  This problem only affects
systems on which procfs or linprocfs is mounted.

- Pass only pointer to struct ip to ng_netflow_flow_add(). Any TCP/UDP
