85986016ae Increase initially dropped bytes from 512 to 768 (768 is also 
suggested in the Ilya Mironov's article). 768 taken from another
research where it treats as default for RC4-drop(768):
http://www.users.zetnet.co.uk/hopwood/crypto/scan/cs.html#RC4-drop

Minor style tweak.

df9cf830d1 Trying to fix compilation bustage: 
- removing 'const' qualifier from an input parameter to conform to the type
  required by rw_assert();
- using in_addr->s_addr to retrive 32 bits address value.

09400d5abe - Disallow XFS mounting in write mode. The write support never worked really 
and there is no need to maintain it.
- Fix vn_get() in order to let it call vget(9) with a valid locking
  request.  vget(9) returns the vnode locked in order to prevent recycling,
  but in this case internal XFS locks alredy prevent it from happening, so
  it is safe to drop the vnode lock before to return by vn_get().
- Add a VNASSERT() in vget(9) in order to catch malformed locking requests.

a08f5d95ec 1) Use __packed attr on rdat structure to make it exact 128 bytes. 
2) Use gettimeofday() and getpid() only if reading from /dev/urandom
fails or impossible.
3) Discard N bytes on very first initialization only (i.e. don't
discard on re-stir).
4) Reduce N from 1024 to 512 as really suggested in the
"(Not So) Random Shuffles of RC4" paper:

847bd80810 Allocate a single CCB at the start of the main loop of the RAID monitoring 
kthread of the mpt(4) driver that hangs around for the entire lifetime of
the thread.  Previously the driver would allocate a new CCB using M_WAITOK
with a lock held each time it updated its state.  While here, use the
CAM API for allocating a CCB rather than raw malloc(9).

This MAY be combined by a clever person with the 'key' code recently
added, however a cursary glance suggest that it would be safer to just keep
the patches as it is unlikely that the two modes would be used together
and the separate patch has been extensively tested.

6ae8b92a79 tcsh: fix abort in cleanup_until(), caused by internal xgetpass() 
The xgetpass() function pushes a cleanup entry for &osa, but then
attempts to flush the stack until an entry matching &sa.  The two
object pointers do not match, so the stack is popped too much,
and then cleanup_until calls abort() when it unexpectedly hits
the bottom of the cleanup stack.
