dd3cca2bda Actual firewall change.
1) Firewall is not subdivided on forwarding / blocking chains
   anymore.Actually only one chain left-it was the blocking one.
2) LKM support.ip_fwdef.c is function pointers definition and
goes into kernel along with all INET stuff.

5f4f867140 Firewall can be used as lkm module.To use it
firewall should *NOT* be compiled into kernel.
Then it can  be loaded.This is misc module but i'v
got no problemms with it,so shouldn't you i suppose..
BTW this is very stupid to have one module in CVS
for ALL lkm's...

44bbcce705 First round in syscons update. Several new features has been added:
No kernel config options anymore besides keyboard language layout.
Virtual consoles are now dynamically allocated, no NCONS anymore.
Software cursor blinking/nonblinking.
Visual bell for laptops (don't beep at meetings :-).
Cursor/bell default type setable via config "flags" instead of as defines.
Cursor/bell type setable via ioctl's.
New video modes 80x30 80x60 for some laptops, and those with multisync monitors.
Scroll-lock history (length currently fixed at 100 lines).
Lots of cleanups, some only commented out for now (will goaway soon).
Support for new features in vidcontrol/kbdcontrol.
Updated manpages.

0701af54e9 Finally implement support for the `lsdev' program. The controller is
now marked busy as long as it's being in non-reset state, and the
drives are busy as long as at least one instance is open.

Also reformat everything to fit into 80 columns again.

Changed my mind wrt. error reporting for a write-protected drive and
an open() with write intent; ENXIO has been too weird, now return EIO.
Some portions of the code need to be rewritten to use tprintf()
instead of simple printf()'s, so the messages will also appear on the
session terminal, however.

1707d41102 These changes embody the support of the fully coherent merged VM buffer cache,
much higher filesystem I/O performance, and much better paging performance. It
represents the culmination of over 6 months of R&D.

The majority of the merged VM/cache work is by John Dyson.

The following highlights the most significant changes. Additionally, there are
(mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to
support the new VM/buffer scheme.

vfs_bio.c:
Significant rewrite of most of vfs_bio to support the merged VM buffer cache
scheme.  The scheme is almost fully compatible with the old filesystem
interface.  Significant improvement in the number of opportunities for write
clustering.

vfs_cluster.c, vfs_subr.c
Upgrade and performance enhancements in vfs layer code to support merged
VM/buffer cache.  Fixup of vfs_cluster to eliminate the bogus pagemove stuff.

vm_object.c:
Yet more improvements in the collapse code.  Elimination of some windows that
can cause list corruption.

vm_pageout.c:
Fixed it, it really works better now.  Somehow in 2.0, some "enhancements"
broke the code.  This code has been reworked from the ground-up.

vm_fault.c, vm_page.c, pmap.c, vm_object.c
Support for small-block filesystems with merged VM/buffer cache scheme.

pmap.c vm_map.c
Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of
kernel PTs.

vm_glue.c
Much simpler and more effective swapping code.  No more gratuitous swapping.

proc.h
Fixed the problem that the p_lock flag was not being cleared on a fork.

swap_pager.c, vnode_pager.c
Removal of old vfs_bio cruft to support the past pseudo-coherency.  Now the
code doesn't need it anymore.

machdep.c
Changes to better support the parameter values for the merged VM/buffer cache
scheme.

machdep.c, kern_exec.c, vm_glue.c
Implemented a seperate submap for temporary exec string space and another one
to contain process upages. This eliminates all map fragmentation problems
that previously existed.

ffs_inode.c, ufs_inode.c, ufs_readwrite.c
Changes for merged VM/buffer cache.  Add "bypass" support for sneaking in on
busy buffers.

08cb0571ab Peter's work to work around one of the most annoying bugs in the
floppy driver (or in the hardware?).  It turned out to be caused by
spurious interrupts, right after an FDC reset.

Also major cleanup in the low-level structure, there are now functions
performing error-checks for the FDC I/O.

3d62a40d3f Add VNINACT flag. LFS has a habbit of skipping the ufs_inactive procedure.
It used to do this by setting a global <Yuck>.  Now we set th VNINACT
flag in the vnode to force a skip of ufs_inactive.

11cf69520c LFS stability patches. There is still a problem with directory update
ordering that can prove fatal during large batches of deletes, but this
is much better than it was.  I probably won't be putting much more time
into this until Seltzer releases her new version of LFS which has
fragment support.  This should be availible just before USENIX.
