fba2e6106f Quick fix for non-unique inode numbers for hard links. We use the
byte offset of the directory entry for the inode number for all types
of files except directories, although this breaks hard links for
non-directories even if it doesn't cause overflow.  Just ignore this
broken inode number for stat() and readdir() and return a less broken
one (the block offset of the file), so that applications normally can't
see the brokenness.

This leaves at least the following brokenness:
- extra inodes, vnodes and caching for hard links.
- various overflow bugs.  cd9660 supports 64-bit block numbers, but we
  silently ignore the top 32 bits in isonum_733() and then drop another
  10 bits for our broken inode numbers.  We may also have sign extension
  bugs from storing 32-bit extents in ints and longs even if ints are
  32-bits.  These bugs affect DVDs.  mkisofs apparently limits them
  by writing directory entries first.

Inode numbers were broken mainly in 4.4BSD-Lite2.  FreeBSD-1.1.5 seems
to have a correct implementation modulo the overflow bugs.  We need
to look up directory entries from inodes for symlinks only.  FreeBSD-1.1.5
use separate fields (iso_parent_extent, iso_parent) to point to the
directory entry.  4.4BSD-Lite doesn't have these, and abuses i_ino to
point to the directory entry.  Correct pointers are impossible for
hard links, but symlinks can't be hard links.

243917fe3b Lock down a socket, milestone 1.
o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
  socket buffer. The mutex in the receive buffer also protects the data
  in struct socket.

o Determine the lock strategy for each members in struct socket.

o Lock down the following members:

  - so_count
  - so_options
  - so_linger
  - so_state

o Remove *_locked() socket APIs.  Make the following socket APIs
  touching the members above now require a locked socket:

 - sodisconnect()
 - soisconnected()
 - soisconnecting()
 - soisdisconnected()
 - soisdisconnecting()
 - sofree()
 - soref()
 - sorele()
 - sorwakeup()
 - sotryfree()
 - sowakeup()
 - sowwakeup()

f44d9e24fb Change p_can{debug,see,sched,signal}()'s first argument to be a thread
pointer instead of a proc pointer and require the process pointed to
by the second argument to be locked.  We now use the thread ucred reference
for the credential checks in p_can*() as a result.  p_canfoo() should now
no longer need Giant.

8eee3a3d58 Fix several bugs in devfs_lookupx(). When we check the nameiop to
make sure it's a correct operation for devfs, do it only in the
ISLASTCN case.  If we don't, we are assuming that the final file will
be in devfs, which is not true if another partition is mounted on top
of devfs or with special filenames (like /dev/net/../../foo).

a92e7c792a - Change procfs_control()'s first argument to be a thread pointer instead
of a process pointer.
- Move the p_candebug() at the start of procfs_control() a bit to make
  locking feasible.  We still perform the access check before doing
  anything, we just now perform it after acquiring locks.
- Don't lock the sched_lock for TRACE_WAIT_P() and when checking to see if
  p_stat is SSTOP.  We lock the process while setting p_stat to SSTOP
  so locking the process is sufficient to do a read to see if p_stat is
  SSTOP or not.

11257f4d1a Fixed assorted bugs in setting of timestamps in devfs_setattr().
Setting of timestamps on devices had no effect visible to userland
because timestamps for devices were set in places that are never used.
This broke:
- update of file change time after a change of an attribute
- setting of file access and modification times.

The VA_UTIMES_NULL case did not work.  Revs 1.31-1.32 were supposed to
fix this by copying correct bits from ufs, but had little or no effect
because the old checks were not removed.

Bruce Evans
32a95d83f9 Fixed a very old bug in setting timestamps using utimes(2) on msdosfs
files.  We didn't clear the update marks when we set the times, so
some of the settings were sometimes clobbered with the current time a
little later.  This caused cp -p even by root to almost always fail
to preserve any times despite not reporting any errors in attempting
to preserve them.

Don't forget to set the archive attribute when we set the read-only
attribute.  We should only set the archive attribute if we actually
change something, but we mostly don't bother avoiding setting it
elsewhere, so don't bother here yet.
