I decided to do this for every hardclock() call instead of lazily
in microtime(). The lazy method is simpler but has more overhead
if microtime() is called a lot.
CPU_THISTICKLEN() is now a no-op and should probably go away.
Previously it did nothing directly but had the side effect of
setting i586_last_tick for CPU_CLOCKUPDATE() and i586_avg_tick for
debugging. CPU_CLOCKUPDATE() now uses a better method and
i586_avg_tick is too much trouble to maintain.
Reduced nesting of #includes in the usual case.
Increased nesting of #includes when CLOCK_HAIR is defined. This
is a kludge to get typedefs for inline functions only when the
inline functions are used. Normally only kern_clock.c defines
this. kern_clock.c can't include the i386 headers directly.
Removed unused LOCORE support.
break when I remove LOCORE support from clock.h.
I586_CTR_MULTIPLIER_SHIFT = 32 from clock.h is actually still used, but
32 is so magic that it doesn't get used explicitly.
- Add support for memory mapped I/O.
- Use DMA to get SCBs down to the adapters.
- Remove old paging code.
- Be much smarter about how we allocate SCB space. The old, simple method
wasted almost half a page per SCB. Ooops.
- Make command complete interrupt processing more efficient.
- Break the monolithic ahc_intr into sub-routines. The sub-routines handle
rare, special case events so the function call is not a penalty and the
removal of the code from the main routine most likely improves performance
instruction prefech will work better and less code is pushed into the cache.
- Never, ever allow tagged queueing if a device has disconnection disabled.
- Clean up and simplify timeout code. Many of the changes are to handle the
new DMA scheme.
SCB paging is now handled almost entirely by the sequencer and also uses
DMA. This should make SCB paging at least an order of magnitude more
efficient and vastly simplifies the implementation.
Add a few space optimizations so this code still fits on aic7770 chips.
Update comments.
any maps that may have them. If the YP_SECURE key is present, ypserv
will only allow access to the map from clients on reserved ports.
If the YP_INTERDOMAIN key is present, the server will do DNS lookups
for hostnames that it can't find in hosts.byname or hosts.byaddr.
This is the same as the -d flag (which is retained for backwards
compatibility) but it can be set on a per-map/per-domain basis.
Also modified /var/yp/Makefile to add YP_INTERDOMAIN to the hosts.*
maps and YP_SECURE to master.passwd.* maps by default.
the main program, report them directly from the dynamic linker and die
there, rather than returning an error message to crt0.o. This enables
the printing of error messages even for old executables, whose version
of crt0.o is not able to print them.
This fix closes PR bin/1869.
The code in crt0.o for printing error messages from the dynamic linker
is no longer used, because of this change. But it must remain, for
backward compatibility with older dynamic linkers.
map databases. Also document said flags in the man page.
Adding YP_INTERDOMAIN to a map causes ypserv(8) to do a DNS lookup
when a yp_match() on the map fails. (This affects only the hosts.by*
maps; for all other maps it's ignored.) The YP_SECURE entry causes
ypserv(8) to restrict access to the map so that only clients making
requests from reserved ports can get at it.
Our ypserv doesn't currently support these features so they're silently
ignored for the moment, but this will change. :)

The sed script in /etc/rc.local that builds the host/kernel ID line
for the message of the day relies on the year not going past 1999.
When the year passes 1999, the ID line is malformed.

find two users with the same UID (i.e. root and toor), but yp_mkdb(8)
forbits duplicate keys, so only one of them will end up in the *.byuid
maps (probably toor, since it comes after root in the template file).
If I asked rpc.yppasswdd(8) to change toor's password, it would update
the *.byname maps correctly, but incorrectly modify root's entry in
the *.byuid maps since the only matching record with UID=0 in those
maps belongs to root.
To fix this, we check that both the name and UID are correct before trying
to write new entries to the maps.

I PROMISE I'll remove that as soon as I have the makefiles etc fixed as well.

after I installed the last SNAP :). Because of the way the 'use NIS
or local?' logic is set up here, it was possible to force the use
of the NIS password changer even though the specified user didn't exist
in NIS (i.e. # passwd foo, where foo is a local-only user). In this
case, we fall intp yp_passwd() without the corresponding yp_password
structure being filled in, which leads to an NULL pointer dereference.
Also fixed the logic like I just did with chpass so that if the user
is both in NIS and the local password database, the program makes a
more sensible guess as to which one to use (if NIS is turned on in
/etc/master.passwd, then use NIS, else default to local).
enabled in /etc/master.passwd & friends. This allows the 'USER_YP_AND_LOCAL'
case to make a more sensible guess (if NIS is enabled, default to NIS,
otherwise default to local -- this is better than defaulting to NIS
all the time).

Also, document and place in an opt_ file the #define's for overriding which
serial port is the system console.
