is called prior to sending a CCP configure request for a
given protocol. The default is to send the request, but
this is overridden for MPPE which checks to see if the lcp
negotiations agreed CHAP81, and if not fails.
Use the same function to decide if we should reject peer
requests for MPPE.
This should get rid of those boring messages about not being
able to initialise MPPE when we don't negotiate CHAP81.
except for setting it. Also remove count from aha and replace it with
optional.
Also add commented out pccard lines for all the old card drivers.
They have to be commented out until they are converted because it
causes problems in NEWCARD.
There are two 3rd party code chunks using this still - the IPv6 stuff and
i4b. Give them a private copy as an alternative to changing them too much.
XXX sys/kernel.h still has a #include <sys/module.h> in it. I will be
taking this out shortly - this affects a number of drivers.
by myself. It solves a serious vm_map corruption problem that can occur
with the buffer cache when block sizes > 64K are used. This code has been
heavily tested in -stable but only tested somewhat on -current. An MFC
will occur in a few days. My additions include the vm_map_simplify_entry()
and minor buffer cache boundry case fix.
Make the buffer cache use a system map for buffer cache KVM rather then a
normal map.
Ensure that VM objects are not allocated for system maps. There were cases
where a buffer map could wind up with a backing VM object -- normally
harmless, but this could also result in the buffer cache blocking in places
where it assumes no blocking will occur, possibly resulting in corrupted
maps.
Fix a minor boundry case in the buffer cache size limit is reached that
could result in non-optimal code.
Add vm_map_simplify_entry() calls to prevent 'creeping proliferation'
of vm_map_entry's in the buffer cache's vm_map. Previously only a simple
linear optimization was made. (The buffer vm_map typically has only a
handful of vm_map_entry's. This stabilizes it at that level permanently).

entry fits within its DIRBLKSIZ block. The surrounding code is
extremely fragile with respect to corruption of the directory entry
'd_reclen' field; if directory corruption occurs, it can blindly
scan forward beyond the end of the filesystem block. Usually this
results in a 'fault on nofault entry' panic.
Directory corruption is now much more likely to be detected, resulting
in a 'ufs_dirbad' panic. If the filesystem is read-only, it will
simply print a warning message, and skip the corrupted block.

CLOSE_NORMAL meanings. CLOSE_NORMAL doesn't change the currently
required state, the others do. This should stop ppp from entering
DATALINK_READY when LCP shutdown doesn't end up happening cleanly.
Bump our version number to reflect this change.
in ufs_dirbad(). The mnt_stat.f_flags field is only updated by the
syscalls *statfs and getfsstat, so mnt_flag should be used instead.
This only affects whether or not a panic is generated on detection of
certain types of directory corruption.

using it for auditing purposes.
