2) xs->status was not set to zero during the initialization of a command.
Although I don't think this should be the client's (ie the driver's)
responsibility, it seems that it currently is, so it needs to be cleared.
Without this change, the upper level scsi code will attempt to interpret
the sense information on every command complete (since xs->status is
usually left at 2, "check sense"). This gives a slight performance
increase, as well as stops fooling /sbin/scsi into thinking there was
an error on the command.
3) Document that we support the aic7850 controllers in the aic7870.c

because the call to vget() wasn't checked for failure so the clean

didn't have (which could result in an in-use vnode being freed). The
problem would only be seen during an msync() of the mapped file or
when the file fell off the object cache (although this latter case is

- After a child broadcaster process dies or is killed, set its dom_pipe_fds
descriptors to -1 so that the 'READFD > 0' test in the select() loop
does the right thing.
Since descriptor values can be re-used, failure to do this can lead
to a situation where a descriptor for an RPC socket can be mistaken for
a pipe. If this happens, RPC sockets could be incorrectly handed off to
handle_children(), which would then clear the descriptor from the select()
descriptor mask and prevent svc_getreqset() from handling them. The end
result would be that some RPC events would go unserviced. Curiously,
the failures only happen intermittently.

- the major number wasn't checked, so accesses beyond the end of bdevsw[]

- Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV
(the interface is too braindamaged to say which). -1 was interpreted
as a size and resulted in the bogus error ENOSPC.
- it was possible to set the dumpdev for devices without a d_psize()

it confuses sysctl.

There is much confusion between PAGE_SIZE sized pages and NBPG sized

Not fixed:
- there is nothing to invalidate the dumpdev if the media goes away.
This reduces the benefits of the early calculation of dumplo. Bounds
checking in the dump routines is relied on to reduce the risk of
damage and little would be lost by relying on the dump routines to
calculate dumplo.

Fixes for the following annoyingly subtle bugs:
- ypbindproc_setdom_2 is supposed to be declared void *, not boot_t *,
and it fails to correctly signal failures back to the ypset(8) command:
we need to call one of the svcerr_*() functions (in this case,
svcerr_noprog() seems a logical choice -- we're really cheating
a bit here because nothing else quite fits) to tell ypset that the
attempt to set the binding for a domain failed. If we don't do this,
failed ypset attempts either appear (incorrectly) to succeed, or
they time out.
- The lock handling for child processes isn't quite right. The
child broadcaster processes have to release all locks on the
binding files and the ypbind.lock file.
- The parent ypbind process will SEGV if you do the following:
-- start ypbind with the -ypset or -ypsetme flag
-- type 'ypwhich -d random_unserved_domain'
-- type 'ypset -d random_unserved_domain anyhost'
-- type 'ypwhich -d random_unserved_domain' again
-- wait about 60 seconds
What happens is this: the ypwhich command causes ypbind to fork a
broadcaster process that searches for a server for random_unserved_domain.
If you then use ypset to force a binding while this process is still alive,
the state flags that tell the ypbind parent process that the child
is running will be cleared. The second ypwhich command then causes
a *second* child process to be forked for random_unserved_domain,
which is verbotten. When the first broadcaster exits and tells the
parent that it wasn't able to find a server for the domain, the parent
clobbers the entry for random_unserved_domain. Then the second broadcaster
exits and the same thing happens, only trying to clobber the entry
twice causes a SEGV.
The fix for this is a slight change in program structure: since we
can't have more than one broadcaster for a given domain at a time,
we save the pipe descriptors and pid for the child broadcaster in members
of the _dom_binding struct for the domain. (As a side effect, we
can get rid of the global child_fds variable.) So when rpc_received()
finds that it's been asked to do a ypset for a domain for which a
broadcaster process exists, it sends a SIGINT to the child to kill it
and closes the pipe to the now-dead child. This keeps everything in sync
and insures that we don't leak file descriptors.
- ping() should be using YPPROC_DOMAIN rather than YPPROC_DOMAIN_NONACK
when it does its clnt_call() to the server.
- Removed the check for client_handle == NULL in ping() and make
client_handle local to ping instead of a member of the _dom_binding
struct. This fixes another potential ypset problem: using ypset to
force a binding to a machine that has an NIS server but which *doesn't*
support the domain we're after can result in permanently bogus bindings.
- the 'server OK' message prints the wrong IP address.

The `howto' arg to boot() was not supplied, so it was stack garbage (actually
the return address in the boot program). I didn't use the submitted fix.
1) If a target initiated a sync negotiation with us and happened to chose a
value above 15, the old code inadvertantly truncated it with an "& 0x0f".
If the periferal picked something really bad like 0x32, you'd end up with
an offset of 2 which would hang the drive since it didn't expect to ever
get something so low. We now do a MIN(maxoffset, given_offset).
2) In the case of Wide cards, we were turning on sync transfers after a
sucessfull wide negotiation. Now we leave the offset alone in the per
target scratch space (which implies asyncronous transfers since we initialize
it that way) until a syncronous negotation occurs.
3) We were advertizing a max offset of 15 instead of 8 for wide devices.
4) If the upper level SCSI code sent down a "SCSI_RESET", it would hang the
system because we would end up sending a null command to the sequencer. Now
we handle SCSI_RESET correctly by having the sequencer interrupt us when it
is about to fill the message buffer so that we can fill it in ourselves.
The sequencer will also "simulate" a command complete for these "message only"
SCBs so that the kernel driver can finish up properly. The cdplay utility
will send a "SCSI_REST" to the cdplayer if you use the reset command.
5) The code that handles SCSIINTs was broken in that if more than one type
of error was true at once, we'd do outbs without the card being paused.
The else clause after the busfree case was also an accident waiting to
happen. I've now turned this into an if, else if, else type of thing, since
in most cases when we handle one type of error, it should be okay to ignore
the rest (ie if we have a SELTO, who cares if there was a parity error on
the transaction?), but the section should really be rewritten after 2.0.5.
This fix was the least obtrusive way to patch the problem.
6) Only tag either SDTR or WDTR negotiation on an SCB. The real problem is
that I don't account for the case when an SCB that is tagged to do a particular
type of negotiation completes or SELTOs (selection timeout) without the
negotiation taking place, so the accounting of sdtrpending and wdtrpending
gets screwed up. In the wide case, if we tag it to do both wdtr and sdtr,
it only performs wdtr (since wdtr must occur first and we spread out the
negotiation over two commands) so we always have sdtrpending set for that
target and we never do a real SDTR. I fill properly fix the accounting
after 2.0.5 goes out the door, but this works (as confirmed by Dan) on
wide targets.
Other stuff that is also included:
1) Don't do a bzero when recycling SCBs. The only thing that must explicitly
be set to zero is the scb control byte which is done in ahc_get_scb. We also
need to set the SG_list_pointer and SG_list_count to 0 for commands that do
not transfer data.
2) Mask the interrupt type printout for the aic7870 case. The bit we were
using to determine interrupt type is only valid for the aic7770.

with davidg about it, I hereby kill two undocumented misfeatures:
The code to skip a miniroot in the swapdev is not particular useful, and
if we need it we need it to be done properly, ie size the fs and skip all
of it not some hardcoded size, and subtract what we skip from the length
in the first place.
The SEQSWAP dies too. It's not the way to do it, it doesn't work, and
nobody have expressed any great desire for it to work. The way to
implement it correctly would be a second argument to swapon(2) to give
a priority/policy information. Low priority swapdevs can be made so
by adding them at a far offset (0x80000000 kind of thing), with almost no
modification to the strategy routine (in particular a offset per swapdev).
But until the need is obvious, it will not be done.

to access it. setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.
Call setdelayed() every (normal) clock tick to convert delayed

Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick. This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.

- Make the child process reaper signal-driven. (Previously, we called reaper()
once a second each time we went through the select() loop. This was
convenient, but inefficient.)
- Increase main select() timeout from 1 second to 60 seconds and use
this as the ping timer instead of using timestamps in the _dom_binding
structure. This nd the reaper() change noted above makes ypbind a little
less CPU-intensive.
- Don't flag EINTR's from select() as errors since they will happen as a
result of incoming SIGCHLD's interrupting select().
- Prevent possible resource hogging. Currently we malloc() memory
each time a user process asks us to establish a binding for a domain,
but we never free it. This could lead to serious memory leakage if a
'clever' user did something like ask ypwhich to check the bindings
for domains 0.0.0.0.0.0.0.0.0.0 through 9.9.9.9.9.9.9.9.9.9 inclusive.
(This would also make a mess out of the /var/yp/binding directory.)
We now avoid this silliness by a) limiting the maximum number of
simultaneous bindings we can manage to 200, and b) free()ing _dom_binding
structures of secondary domains whose servers have stopped responding.
We unlink the /var/yp/binding/domain.vers files for the free()ed
domains too.
(This is safe to do since a client can prod us into reestablishing the
binding, at which time we'll simply allocate a new _dom_binding structure
for it.)
We keep count of the total number of domains. If asked to
allocate more than the maximum, we return an error. I have yet to hear
of anybody needing 200 simultaneous NIS bindings, so this should be
enough. (I chose the number 200 arbitrarily. It can be increased if need
be.)
- Changed "server not responding"/"server OK" messages to display server
IP addresses again since it looks spiffier.
- Use daemon() to daemonify ourselves,
- Added a SIGTERM handler that removes all binding files and unregisters
the ypbind service from the portmapper when a SIGTERM in received.
- The comment 'blow away everything in BINDINGDIR' has no associated code.
Give it some: clean out /var/yp/binding at startup (if it exists).
This completes my ypbind wishlist. Barring bug fixes, I shouldn't need to
go poking around in here anymore. (Of course, this means I can start

the adapter's selections. Many fast periferals were getting upset when
the sequencer decided to rearbitrate after the device had already won
arbitration. This also forced the creation of a list threaded through
the SCBs (since we don't have enough space anywhere else) of commands that
are awaiting reselection. This list is run down before any new transactions
from the input queue are allowed. The list is appened to whenever we begin
a selection (simple case since the selecting device is always at the head)
and by the kernel driver whenever a request sense occurs. In the common
case, the list is only one element long, but when a reselection wins out
over a selection and that reselection generates a request sense, the
outstanding selection required for the retreval of the sense code grows
the list. On machines with many targets, this might cause the list to grow
large, so this solution, which will allow up to the maximum number of I/O
requests capible of the card elements in the list, was chosen. The list
manipulation is trivial and adds three sequencer instructions of overhead
to the selection phase.
This fixes the "target busy" errors from micropolis drives and the bursty
I/O problem when performing I/O between a Quantum Grand Prix and any other
device. I anticipate that this will correct many of the problems that

- Moved to a more client-driven model. We aggressively attempt to keep
the default domain bound (as before) but we give up on non-default
domains if we lose contact with a server and fail to get a response
after one round of broadcasting. This helps drastically reduce the
amount of network bandwitdh that ypbind consumes: if a client references
the secondary domain at some later point, this will prod ypbind into
establishing a new binding anyway, so continuously broadcasting without
need is pointless.
Note that we still actively seek out a binding for our default domain
even if no client program has queried us yet. I'm not exactly sure if
this matches SunOS's behavior or not, but I decided to do it this way
since we can get into all sorts of trouble if our default domain comes
unbound. Even so, we're still much quieter than we used to be.
- Removed a bunch of no-longer pertinent comments and a couple of
chunks of #ifdef 0'ed code that no longer fit in to the new layout.
- Theo deRaadt must have become frustrated with the callback mechanism
in clnt_broadcast(), because he shamelessly stole the clnt_broadcast()
code right out of the RPC library and hacked it up to suit his needs.
(Comments and all! :)
I can understand why: clnt_broadcast() blocks while awaiting replies.
Changing this behavior requires surgery. However, you can work around
this: fork the broadcast into a child process and relay the results
back to the parent via a pipe. (Careful obervation has shown that the
SunOS ypbind forks children for broadcasting too, though I can only
guess what sort of interprocess communication it uses. pipe() seems to
do the job well enough.)
This may seem like the long way around, but it's not really that
hard to implement, and I'd prefer to use documented RPC library functions
wherever possible. We're careful to limit the number of simultaneous
broadcasters to avoid swamping the system (the current limit is 5).
Each clnt_broadcast() call only sends out a small number of packets
at increasing intervals. We're also careful not to spawn more than one
bradcaster for a given domain.
- Used clntudp_bufcreate() and clnt_call() to implement a ping()
function for directly querying a particular server so that we can
check if it's still alive. This lets me completely remove the old
bradcasting code and use actual RPC library calls instead, at the
cost of more than a few handfulls of torn-out hair. (Make no mistake
folks: I *HATE* RPC.) Currently, the ping interval is one minute.
- Fixed another potential 'nfds too big for select()' bug: use
_rpc_dtablesize() instead of getdtablesize().
- Quieted gcc -Wall a bit.
- Probably a bunch of other stuff that I've forgotten.
ypbind.8:
- Updated man page to reflect modifications.
ypwhich.c:
- Small mind-o fix from last time: decode error results from
ypbind correctly (*groan*)
yplib.c:
- same as above
- Change behavior of _yp_dobind() a little: if we get back a 'Domain
not bound' error for a given domain, retry a few times before giving
up and passing the error back to the caller. We have to sleep for a
few seconds between tries since the 'Domain not bound' error comes
back immediately (by repeatedly looping, we end up pounding on ypbind).
We retry at most 20 times at 5 second intervals. This gives us a full
minute to get a response. This seems to deviate a bit from SunOS
behavior -- it appears to wait forever -- but I don't like the idea
of perpetually hanging inside a library call.
Note that this should fix the problems some people have with bindings
not being established fast enough at boot time; sometimes amd is started
in /etc/rc after ypbind has run but before it gets a binding set up. The
automounter gets annoyed at this and tends to exit. By pausing ther YP
calls until a binding is ready, we avoid this situation.
- Another _yp_dobind() change: if we determine that our binding files
are unlocked or nonexistent, jump directly to code that pokes ypbind
into restablishing the binding. Again, if it fails, we'll time out
eventually and return.

Change the interfaces of these functions to save space. The code
that takes the least amount of space is often the opposite to what

even when the constant is already in a register).
Rewrite getbootdev() to save 80 bytes of space and to make it less

simply push %edx and access only one byte in the callee. Instead,
it sometimes unnecessarily spills %edx; it always sign extends

if_tun_mod, etc...) from crashing the system. These modules are useful,
but because they don't yet have proper load()/unload() functions,
they can lead to panics: if, for example, you load the if_ppp module,
any user can panic the system by running modstat.
You can also hang the system outright if you try to unload the PPP
module too.
Changes are as follows:
- Save the name passed to us during the RESERVE stage for name matching
(we can't load if_ppp_mod twice: we've have two ppp0's and two ppp1's,
which is beyond strange). This makes the lkmexists() cheks somewhat
redundant, but there's no way around it that I can see.
- If we call the module entry point and find that we have no lkm_any
structure in our 'private' section, create a fake one. This keeps
modstat happy. We mark such modules as LM_UNKNOWN.
- Don't allow LM_UNLOAD modules to be unloaded: it just ain't
possible. (Unless someone wants to write a pppunattach() function. :( )
- In lkmunreserve(), mark private.lkm_any as NULL so we don't get
confused later. I think this is bogus, but I can't prove it.

the top level and have the build-package sequence of each port work

For the old behavior (i.e, just go ahead and blindly pack everything up,
regardless of the contents of work/), there is a new target "repackage".
Since "build" depends on "configure", which depends on "patch", etc.,
this shouldn't disrupt any Makefile that doesn't break the dependency
chain.
The old behavior was very annoying because when I did a "make -k",
it would still try to go configure and build even if the extraction
failed.
The first problem I found was that descriptor 0 was being closed.
This happens because the modem variable is set to 0 to indicate
that it is not valid but there are not enough tests for the modem
variable being 0. You can see where I have done this in the patch.
Code in OpenModem() dups the modem descriptor if it is < 3. Once
this happened the modem was always open and an incomming call would
have getty and ppp reading the modem.
Descriptor 1 is closed when the quit command was executed from a
telnet connection. The next modem open returns descriptor 1
and this gets duped leaving the modem always open again.
The modem was not being closed when the connection dropped or was
closed from the other end. The UUCP lock was also not removed if
the modem could not be opened.

one ypbind broadcast can yield several responses. This can lead to
some confusion: the syslog message from ypbind will indicate a rebinding
to the first server that responds, but we may subsequently change our
binding to another server when the other responses arrive. This results
in ypbind reporting 'server OK' to one address and ypwhich reporting a
binding to another.
The behavior of the rpc_received() function has been changed to prevent
this: subsequent responses received after a binding has already been
established are ignored. Rebinding gratuitously each time we get a
new response is silly anyway.

binding requests are supposed to be 'client-driven.' The _yp_dobind()

calls from client programs rather than having ypbind broadcasting
continously until a server responds. The current setup works okay in
normal operation, but we broadcast far too often than we should.)

The declaration for pentium_mhz is hidden inside an #ifdef I586_CPU,
but machdep.c refers to it whether I586_CPU is defined or not. This
temporary hack puts the offending code inside an #ifdef I586_CPU as
well so that a kernel without it will successfully compile.
I must emphasize the word 'temporary:' somebody needs to seriously
beat on the identifycpu() function with an #ifdef stick so that
I386_CPU, I486_CPU and I586_CPU will do the right things.

where one or more of the non-default domains are not yet bound.
If we make a YP request for a domain other than the default domain,
and there is no binding for the new domain yet, _yp_dobind() sees
that the /var/yp/binding/DOMAIN.VERS file for the unbound domain is
not locked (by ypbind) and from this it concludes that the NIS system
is dead, so it gives up.
This behavior has been changed: before giving up in this case, we now
make a second check to see if the binding file for the *default* domain
is also not locked. Only if the default domain binding file is also
unlocked to we now assume that ypbind has bought the farm and bail out.
(Note: this assumes that the user hasn't changed the default domain
while ypbind is running.)
With this change, _do_ypbind() is allowed to proceed into the next
section of code wherein it prods ypbind into establishing a binding
for the new domain. This first call times out after ten seconds,
after which it should retry and succeed. From then on, the binding
for the second domain should be handled normally.

it finds the required package(s) in the same directory as the package

2 remaining flaws:
1. pkg_add looks in one place (where you were when you loaded the primary
pkg) for depended packages. If you can come up with a search path scheme
that's not a total hack - be my guest!
2. Recursive dependency expansion can result in the name of a dep being
listed more than once. This doesn't bother pkg_add since it checks
for package existance with pkg_info and will skip already-loaded packages.

reevaluate its args. I used a hack controlled by

This has the advantage that the core of the functions is only

register ourselves as an NIS version 1 UDP server to pacify older SunOS 4
ypbinds that seem to insist on having one around. All this does is allow
ypserv to respond to DOMAIN_NONACK requests that are periodically

server in any other way.
Unlike the mainline code, which implements this as a compile-time
option, this feature can be turned on with the newly-added -k flag

select() returns EINVAL if you try to feed it a value of FD_SETSIZE greater
that 256. You can apparently adjust this by specifying a larger value of
FD_SETSIZE when configuring your kernel. However, if you set the maximum
number of open file descriptors per process to some value greater than
the FD_SETSIZE value that select() expects, many selects() within the RPC
library code will be botched because _rpc_dtablesize() will return
invalid numbers. This is to say that it will return the upper descriptor
table size limit which can be much higher than 256. Unless select() is
prepared to expect this 'unusually' high value, it will fail. (A good
example of this can be seen with NIS enabled: if you type 'unlimit' at
the shell prompt and then run any command that does NIS calls, you'll
be bombarded with errors from clnttcp_create().)
A temporary fix for this is to clamp the value returned by _rpc_dtablesize()
at FD_SETSIZE (as defined in <sys/types.h> (256)). I suppose the Right
Thing would be to provide some mechanism for select() to dynamically
adjust itself to handle FD_SETSIZE values larger than 256, but it's a
bit late in the game for that. Hopefully 256 file descriptors will be enough
to keep RPC happy for now.

Have you been plagued by long waits when your NIS server is rebooted?
READ ON!
Sun has a patch, but the README says:
********************* WARNING ******************************
This is a new version of ypbind that never uses the NIS
binding file to cache the servers binding. This will have
the effect of fixing the current symptom. However, it might
degrade the overall performance of the system when the
server is available. This is most likely to happen on an
overloaded server, which will cause the network to produce
a broadcast storm.
*************************************************************
Therefor, I have produced another fix.
o What goes wrong.
When the NIS server is rebooted, ypserv will obtain different ports
to listen for RPC requests. All clients will continue to use the old
binding they obtained earlier. The NIS server will send ICMP dst unreachable
messages for the RPC requests that arrive at the old port. These ICMPs
are dropped on the floor and the client code will continue sending the
requests until the timer has expired. The small fix at the end of this
message will pick up these ICMP messages and deliver them to the RPC layer.
o Before and after.
I've tested this on some machines and this is the result:
(kill and restart ypserv on the server)
original% time ypmatch user passwd
user:....
0.040u 0.090s 2:35.64 0.0% 0+126k 0+0io 0pf+0w (155 seconds elapsed time)
fixedhost% time ypmatch user passwd
user:....
0.050u 0.050s 0:10.20 0.9% 0+136k 0+0io 0pf+0w (10 seconds elapsed time)
Rebinding is almost instantaneous.
o Other benefits.
RPC calls that use UDP as transport will no longer time out but
will abort much sooner. (E.g., the remote host is unreachable or
111/udp is filtered by an intermediate router)
ypxfr can't easily be reduced down to one file like yppush because it
needs to do certain special things (such as binding to a specific

ypbind is supposed to create it but it doesn't. This is because when
it checks the return value for the attempted open() of
/var/yp/binding/DOMAIN.VERSION, it tests only for a value of -1. This
is bogus because open() doesn't return -1 in this case. Now it checks
for < 0 instead.
This should make life easier for many NIS-newbies who would otherwise
be left scratching their heads wondering why the NIS client stuff won't
work despite their best efforts. ("I set the domain name on my machine,
and /var/yp exists, but when I start ypbind and try a 'ypcat passwd,'
it says it can't bind to a server for this domain! Please help!")

to poll succesfully even if we are sharing the interrupt.

This commit makes the 294x PCI shared interrupt compliant. This has

- Report valid residual byte counts. We actually pause the sequencer
when the residual is non-zero. I thought about using DMA to do this,
bus sequencer program space is tight.
- Fix embarassing off by one error in the computation of a 2's
compliment variable. This was most likely the cause of the
many problems reported with the tagged queuing code.
- Handle "MAX_SYNC" as a special case (ie we are the ones starting
the sync negotiation sequence). This was done so that the target
scratch area can be initialed to 0 offset (asyncronous transfers)
safely. The initialization to 0 (was 15) is necessary since in
some cases a Wide negotiation could run into problems if SCSIRATE
was set wrong and we went into data(in/out).
- Trim the DMA routines a little by using some procedures. Net
effect is more functionality with 3 less instructions after this
update.
- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
last SG block. It has no effect in the 8bit bus configuration,
but in the Wide configuration ensures that the overlap byte is
held in the SCSI block if the transfer is odd so it will end
up in the next SG (the correct behavior).
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
of guessing the right type.
- Add pause variable to the ahc struct to better handle the different
interrupt types and pausing the sequencer.
- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
register in newer Adaptec documentation, so use their name for it.
- Report valid residual byte counts.
- Don't mess with the target scratch areas > id 8 on single, narrow,
channel devices. The BIOS does a checksum of this area and can
flip out if we zero it out.
- Initialize the sequencer FLAGS scratch ram variable in the single
channel devices to 0. This was the cause of the annoying warning
where we would get a cmdcmplt the first time we did any type of
transfer negotiation with no valid scb. It also fixes the problem
that looked like the INTSTAT register wasn't clearing fast enough.
This only showed up on 294x cards, not motherboard aic7870s.
- Add the AHC_AIC7870 type and use it as the superset of aic7870
based controllers.
- clear the sync offset section of the targ scratch area so that
we default to asyncronous transfers. This was only a problem
for wide controllers because there was a scenario where the
offset wouldn't get updated before a data(out/in) phase would
occur. This required some change in the sequencer code since we
were depending on this field to hold the rate to negotiate.
- allow sync and wide negotiated commands to be tagged (the sequencer
now handles this properly).

that ypxfr is supposed to log messages to /var/yp/ypxfr.log if it exists,

It is common case when modem hangs with carier on but don't
receive anything from another side.
This thing commonly healed with hangup and redialing.
Enhancements below allows to determine when such action
is needed and inform attach program with SIGURG signal.
There two ioctls set: outfill and keepalive, used from both
sides of connection. Outfill repeatedly sends FRAME_END with
specified timeout (i.e. 40 seconds). It is needed to get input on
other side even if no user activity on slip line currently.
Keepalive checks FRAME_ENDs from other side, and if no one
got in specified timeout (i.e. 60 seconds, max modem retrain time),
send SIGURG to attach program.
I plan to add code to slattach to handle this thing too.

changes to it based upon other outstanding bug reports and commits made
after his work.
Comments:
(a) sysconfig is still used to do all configuration. I was not going to
change that out from under you.... a user never need edit netstart
or rc* unless they're being very weird.
(b) rc.maint has been folded back into rc. It is just unworkable as
a separate chunk because of ordering bogosities
(c) netstart does what it says... it starts up enough of the network to
get up, it doesn't start every bloody daemon that might talk to a
socket... netstart ifconfig's the devices and sets up routing if
configured to do so.
(d) nfs disks are mounted immediately after netstart completes
(e) syslog is started as early as possible (right after nfs) so that error
messages can get logged to remote syslog servers properly
(f) named is started (there is an argument that says that named should be
started before syslogd because if you are the dns server for your domain,
you'd like named to resolve remote hosts in syslog.conf, but this is
a minority case and the trivial workarround is to put the syslog host
in /etc/hosts or use an /etc/resolv.conf -- why? because you want syslog
to catch named errors, which is a MUCH more important and likely occurance)
(g) NOW all of the rest of the network daemons such as the time stuff, RPC,
NIS, NFS, Kerberos and inetd are started
(h) the rest of the generic stuff is done (cron/printer/sendmail)
(i) shared libraries are set
(j) /etc/rc.i386 is run (this does FreeBSD/386 specific stuff like ibcs2,
xtend, and all of the syscons stuff
(this is actually started as /etc/rc.`uname -m`
(k) the syscons stuff has gotten a serious cleaning to make it consistent
with rc conventions
(l) rc.local has had the comments about syscons removed (they are not relevant
to this file now) and the full name of the kernel has been restored to

you to push the same host into its NFS export lists twice, but mountd
tries to do it anyway. This means that putting:
/some_file_system -ro host1 host1
in your /etc/exports file causes an error. This is bogus: mountd should be
smart enough to ignore the second instance of host1. This can be a problem
in some configurations that use netgroups. For example, each host in my
netgroups database is has two entries:
startide (startide,-,) (startide.ctr.columbia.edu,-,)
When mountd sees this, it tries to put startide.ctr.columbia.edu into the

screw up because mountd will try to resolve the netgroup 'startide' instead
of the hostname 'startide.'

remapping mechanism in the following manner: if given an entry +@foo
and there is no netgroup named 'foo,' try searching for a regular
user group called 'foo' and build the cache using the members of
group 'foo' instead. If both a netgroup 'foo' and a user group 'foo'
exist, the 'foo' netgroup takes precedence, since we're primarily
interested in netgroup matching anyway.
This allows access control schemes based on ordinary user groups
(which are also available via NIS) rather than netgroups, since
netgroups on some systems are limited in really brain-damaged ways.
Note: if you put +::0:0:::::: in /etc/master.passwd as your only NIS
entry, it will cause all NIS uids and gids to be remapped to zero. This
is *intentional*. That's the way it's supposed to work. Enabling NIS with
no remapping at all is done with +:::::::::, not +::0:0::::::. Similarly,
+:::::::::/bin/csh will remap the shells of all NIS users to /bin/csh.
Or, you could do +wpaul:::::::::/bin/csh to remap NIS user wpaul's shell
to /bin/csh but leave everyone else alone.

Today I discovered that rebuilding /usr/include completely from scratch
doesn't work, because the libss Makefile tries to install headers into
/usr/include/ss, which 'make includes' does not create. The result is that
the libss Makefile plants the header files in /usr/include as individual
files called 'ss,' with the second one overwriting the first, and the
third one overwriting the second. So instead of a directory called
/usr/include/ss, you end up with just one file called /usr/include/ss with
only the last header file in it. Check out /usr/include/ss on freefall
and you'll see what I mean.
I've modified the beforeinstall target in the libss Makefile to check
for the presence of the ${DESTDIR}/usr/include/lbss directory and to
create it if it isn't already there. Hopefully I did it right.

table; arptab.c is really a hacked up version of arp.c that only
supports adding temporary entries. (This stuff is nasty -- I wish I
knew what was so wrong with SIOCSARP/SIOCGARP/etc... that made the

client issuing the rarp is expected to be in the middle of booting
and would therefore be unable to answer arp queries from other machines
on the wire. Having rarpd stuff a temporary entry for the booting
host into the local arp table helps keep arp requests from going unanswered.

"Yes Virginia, there is a rarpd."
(Before anyone asks, this *not* the rarpd from NetBSD. It did come from
the same place as theirs, however.)
This is a port of the rarpd program included with the tcpdump-2.0
source code (which I finally unearthed after scrounging around
some of the darker corners of the Internet). It's as close to the
original as I could keep it except for the following changes:
- The original program was based on an older version of the Berkeley
Packet Filter which used different filter programming instructions.
Fortunately, an updated RARP packet filter is available right in the
BPF man page so this was easy to fix.
- The old code didn't know how to deal with variable length addresses
in ifreq buffers. This has been fixed.
- Some byte order weirdness had to be fixed. The sanity checks in
rarp_check() needed some htons()es, and the rarp_reply() function
needed to properly set the ether_type field in the ethernet header
to ETHERTYPE_REVARP before transmitting the packet, otherwise
the bytes in ether_type would wind up reversed. It is important to note
that using htons(ETHERTYPE_REVARP) will not work. This is odd, because
the NetBSD rarpd uses htons(ETHERTYPE_REVARP). (Praise be to tcpdump:
I would never have been able to track this silliness down without it.)
- The update_arptab() function has been castrated. It depends on
SIOCSARP which has been deprecated in 4.4BSD. The NetBSD people
don't seem to be using this function either. It wouldn't be too
hard to replace this with equivalent code from arp.c, but it
might not be necessary.
- I put together an ether_ntohost() support function that allows
both local (/etc/ethers) and NIS lookups. This stuff should go
in libc at some point, but nothing else seems to need it for now,
so it can wait a while.
As you may have guessed, you need to have the Berkeley Packet Filter in
your kernel in order to use this program. The good news is that together
with the recently added bootparamd, you can use finally use a FreeBSD
box to boot Sun boxes over the network. (This was my whole motivation
for getting this stuff to work: I have this one subnet that has a whole
bunch of Sun3 X-terminals on it with only two Sun4 workstations, both
of which are locked in peoples' offices. If those two machines crash
(and they do every so often) then none of the X-terms will boot. Now I
can use a spare PC that I have as a boot server. :)

This is an initial version of bootparamd for FreeBSD based on a public
domain rpc.bootparamd implementation by a gentleman named Klas Heggemann.
This program has apparently been around for a while. The README explicitly
lists the code as public domain, so I guess it's safe to use.
This program is needed for booting diskless SunOS and Solaris machines.
rarpd is also required, but that's in the works too.
I have made two changes to this code:
- Implemented NIS lookups. If /etc/bootparams contains a '+' then the
bootparams map is consulted.
- Allow 0.0.0.0 as a user-specified router address. The SunOS rpc.bootparamd
returns this value in many cases.

Since functions will come and go from libcompat as they are deprecated
it makes no sense to build a shared library out of it as it will change.
Based on freedback from Terry and Jonas on the mailing lists.
Slight change to reverse collapsing so that vm_object_deallocate doesn't
have to be called recursively.
Removed half of a previous fix - the renamed page during a collapse doesn't
need to be marked dirty because the pager backing store pointers are copied
- thus preserving the page's data. This assumes that pages without backing
store are always dirty (except perhaps for when they are first zeroed, but
this doesn't matter).
Switch order of two lines of code so that the correct pager is removed
from the hash list. The previous code bogusly passed a NULL pointer to
vm_object_remove(). The call to vm_object_remove() should be unnecessary
if named anonymous objects were being dealt with correctly. They are
currently marked as OBJ_INTERNAL, which really screws up things (such as
this).
requires complications to adjust the offsets to relative when a block
containing the label is read and back to absolute when such a block is
written. The adjustment is not made on the whole disk slice.
Don't allow setting the offset of partition C to nonzero in in-core labels.
This will cause some (nonstandard) disktab entries to fail. They will
need to be changed to have relative offsets (and no partitions outside
of the slice).
Don't write protect the (nonexistent) label on the whole disk slice.
Writing labels and bootstraps should work right now (except if there is
no DOSpartition table).

Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:
/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.
/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)

Support slice numbers in device names. The syntax is `<driver name>

The existing ypbind exhibits some truly anti-social behavior. After
initially establishing a binding with an NIS server, the following events
take place:
- ypbind waits for 60 seconds before trying to broadcast a ping again
- after the 60 seconds expires, ypbind sends out broadcasts every 5 seconds
come hell or high water.
These broadcasts travel far and wide, even to NIS servers in other domains
which dutifully log the packets even though they don't respond to them.
This leads to lots of unnecessary traffic and bloated log files.
This behavior has been fixed/changed. Here's what happens now:
- We still broadcast every 5 seconds at startup, just like before.
- Once bound, we send out packets once every 60 seconds to the server
we're bound to AND NO ONE ELSE.
- If we fail to receive a reply from our server within FAIL_THRESHOLD
seconds, we assume our server has croaked and go back to broadcasting
everywhere every 5 seconds again until somebody answers. FAIL_THRESHOLD
is currently set to 20 seconds.
Other fixes/improvements:
- ypbind now logs 'server not responding' and 'server OK' messages where
appropriate.

Christians README:
------------------
Hi Everybody!
This is version 1.5 of "fbsdboot", a program that allows you to boot a kernel
from a MS-DOS partition or a FreeBSD partition. This program runs using DOS.
It works with various memory managers (like EMM386, 386MAX) under certain
circumstances.
First, a FreeBSD kernel is always loaded to memory starting at 0x100000. To
assure that loading the kernel *does not* overwrite memory used by memory
managers, high memory for the kernel is allocated and after loading the kernel
it's moved to 0x100000.
Second, there are many ways to switch to protected mode which is necessary to
start the kernel. Each BIOS gives you the possibility to use INT15H (AH=89H)
to do that. But some memory-managers like 386max does not allow you to use
this method.
An other way to do the switch is to use DPMI services, but they do not
guarantee, that the protected mode application is executed with privilege
level 0. Therefore this method is *not* used.
VCPI services offer another way to switch to protected mode, and VCPI servers
are built into "emm386.exe", "386max" and "qemm". That's why, this method is
implemented in fbsdboot.exe.
Fbsdboot.exe tries to switch to protected mode using VCPI services. If they're
not available INT15H is used to do the switch. If that fails, it's not possible
for this version of fbsdboot.exe to boot a kernel :-(.
You can get commandline options of fbsdboot if you start it with "-?" as option!
I don't know, if fbsdboot works with QEMM, as I don't have the possibility to
test it.
Enjoy and have fun!
Christian.

We pretend we have one head with two megabyte worth of sectors per cylinder.
The code try to access another head in what it belives to the same
physical cylinder, because it belives that it would be faster than
waiting for the next free sector under this head to come around.
Most modern drives doesn't have a "classical" geometry, and thus
we end up fooling ourselves doing the above optimization. With this
change we will fill a cylinder sequentially if we can, and thus get
much more mileage from the track-buffer/cache built into the drives.
As a result a lot of seeks to the next or previous track should be
avoided by this.

as an NIS client. The pw_breakout_yp routines that are used to populate the
_pw_passwd structire only do anything if the bits in the pw_fields member
_pw_passwd are cleared. Unfortunately, we can get into a state where
pw_fields has garbage in it right before the YP lookup functions are
called, which causes the breakout functions to screw up in a big way.
Here's how to duplicate the problem:
- Configure FreeBSD as an NIS client
- Log in as a user who's password database records reside only in
the NIS passwd maps.
- Type ps -aux
Result: your processes appear to be owned by 'root' or 'deamon.'
/bin/ls can exhibit the same problem.
The reason this happens:
- When ps(1) needs to match a username to a UID, it calls getpwuid().
- root is in the local password file, so getpwuid() calls __hashpw()
and __hashpw() populates the _pw_passwd struct, including the pw_fields
member. This happens before NIS lookups take place because, by coincidence,
ps(1) tends to display processes owned by root before it happens upon
a proccess owned by you.
- When your UID comes up, __hashpw() fails to find your entry in the
local password database, so it bails out, BUT THE BITS IN THE pw_fields
STRUCTURE OF _pw_passwd ARE NEVER CLEARED AND STILL CONTAIN INFORMATION
FROM THE PREVIOUS CALL TO __hash_pw()!!
- If we have NIS enabled, the NIS lookup functions are called.
- The pw_breakout_yp routines see that the pw_fields bits are set and
decline to place the data retrieved from the NIS passwd maps into the
_pw_passwd structure.
- getpwuid() returns the results of the last __hashpw() lookup instead
of the valid NIS data.
- Hijinxs ensue when user_from_uid() caches this bogus information and
starts handing out the wrong usernames.
AAAARRRRRRRRRGGGGGGHHHHHHHHHH!!!
*Please* don't tell me I'm the only person to have noticed this.
Fixed by having __hashpw() check the state of pw_fields just before
bailing out on a failed lookup and clearing away any leftover garbage.

executes after it finishes updating the raw master.passwd file. The script
is just there to invoke /var/yp/Makefile to build new maps and yppush them.
We could have yppasswdd run /var/yp/Makefile directly, but this allws a bit
more flexibility: the user may decide to run some other commands too.
- FreeBSD's NIS server can supply a master.passwd map, which has
more fields in it than a standard passwd map, so we need a
_master_pw_breakout() fuction.
- When doing passwd map lookups, look for master.passwd.* by attempting
a _yp_first() on master.passwd.byname. If it exists, we're being served
by a FreeBSD NIS server and we should use this map.
- If we aren't the superuser, retrieve only the standard passwd maps.
If we're being served by a FreeBSD system, then the passwd map has
no passwords in it, and it won't serve us the master.passwd map unless
we're superuser anyway.
There's a small speed hit for the superuser inherent in the check for
the master.passwd map, but this lets us dynamically decide what to do
rather than rely on a non-standard config file somewhere. Since all
of this is bypassed for normal users, they shouldn't notice the
difference.
This is a ported/modified version of the yppush program from the
yps-0.21 package from the NYS project. This program is used to propagate
updated NIS maps from an NIS master to an NIS slave. It's normally invoked
by /var/yp/Makefile.
This version of yppush has been modified in the following ways:
- Cleared up several Linux/BSD incompatibilities, largely involving
header files.
- converted from GDBM to DB with extreme predjudice. (well, not really...)
- removed lots of ugly debugging code that really didn't do anyone any good.
- Fixed a couple of inaccurate/badly formatted error messages.
- Renamed some functions to avoid collisions with certain YP routines
hidden inside libc.
- Small signal handling kludge: Linux has different struct sigaction
that us.
- Incorporated some functions from the yps-0.21 library that yppush was
dependent on.
Like ypxfr, this works, but could use come cleaning up.
This is a ported/modified version of the ypxfr program from the yps-0.21
package from the NYS project. This program is normally invoked by ypserv
when it receives a yppush command from an NIS master. It can also be
run from the command line to grab copies of maps when initializing a
slave server.
This program has been hacked in the following ways:
- rpcgen'ed new yp_xdr.c, yp_svc.c and yp_clnt.c files. The old ones were
rather grody.
- Changed certain function names (prefended a _ to them) to avoid conflicts
with certain functions lurking within libc. One major problem here is
that ypxfr needs to bind to a YP master in order to work correctly,
but it can't use the _yp_bind function inside libc because that
function only lets you bind to a domain, not a specific host. Lots
of head scratching here.
- Converted from GDBM to DB at gunpoint.
- Removed lots of really nasty looking DEBUG code to try to reduce clutter.
- Incorporated some of the library code supplied with yps-0.21 on which
ypxfr was dependent.
This program still needs to be cleaned up just as a matter of principle:
I get all icky just looking at it sometimes.
This is a ported/modified version of yppasswd from the NYS yppasswd-0.5
package. This package has code in it from both Olaf Kirch and Theo
de Raadt. There are GPL references and BSD-style copyright all over the
place... hopefully I won't get flamed into oblivion for commiting this.
This program has been modified from the original in the following ways:
- Changed the ALLOW_CHFN and ALLOW_CHSH compile-time options into
run-time options.
- Demolished the password update functions and replaced them with
routines to handle FreeBSD-style passwordd databases. It is expected
that a seperate master.passwd file will be maintained for use with
the NIS maps. yppasswd will have to be told where it is:
% yppasswdd -m /var/yp/master.passwd
A /var/yp/passwd file will be generated from /var/yp/master.passwd by
/var/yp/Makefile. When yppasswdd has finished modifying the master.passwd
file, it will invoke /usr/libexec/yppwupdate, which is a script that
will run /var/yp/Makefile to generate new maps and push them.
Note that there are copies if pw_util.c and pw_copy.c here. This is
deliberate: they are *not* identical to the originals. Very similar, yes,
but not identical. *sigh*
This is a hacked-up port of the ypserv-0.11 server from the NYS project
written by Peter Eriksson.
The original package included some map creating and dumping tools and
was based on GDBM. This version has been modified in the following
ways:
- GDBM replaced with DB and many weird hacks made to the read_database()
function because of this.
- implimented the ypxfr service (using ypxfr from the yps-0.21 package,
aso from the NYS project)
- added code to check the TCP port from which NIS requests originate:
the server will refuse to serve the master.passwd.{byname|byuid} maps
if the request doesn't come from a privileged port. Normally, only the
superuser can issue such a request. Requests for the passwd.{bynam|byuid}
maps aren't affected. There will be a small change made to getpwent.c
in libc to complement this.
- added code to do DNS lookups via actual resolver queries instead of
relying on gethostbyname() and friends. The author noted in the original
documentation that a loop condition could arise where the server would
query itself for hostsname lookups. Using direct DNS lookups prevents
this from happening.
- added code to properly fork() the server into the background unless
invoked with the -debug flag.
- Added combined syslog/perror function.
- fixed a few bugs (which were probably introduced by all the other
changes)
- Created a bmake Makefile.
Note that this package can be linked against the tcp_wrapper package
to provide address-based authentication, but this isn't done by default
since the tcp_wrapper package isn't part of FreeBSD.
This program is used for both generating and dumping NIS maps. It's very
similar to the 'makedbm' command in SunOS. This program was ported from
the yps-0.21 package. It's close to the original except for the GDBM to
DB conversions. This was simple compared to the other YP components.
This is the first round of changes to incorporate YP server functionality
into FreeBSD. This particular change allows passwd to change either the
local or NIS password, as well as the NIS GECOS and shell information.
Essentially, I've taken passwd(1) and yppasswd from the yppasswd-0.5
distribution (which is part of the NYS project -- a project to provide
a GNU GPL'ed suite of NIS tools) and rammed them into each other
at high speed. I've tried my best to make this co-exist with the
Kerberos stuff, but since I don't run Kerberos I don't have an easy
way to verify that it all works. If you choose any Kerberos flags
then the YP checks should be bypassed, but that may not be enough.
I'll modify it some more if it turns out I broke something. For now,
support for localand NIS passwords is pretty solid:
- If you simply type 'passwd,' the program checks to see if you exist
in the local pwd.db database. If not, you get bounced to YP.
- If you try to force local functionality with the -l flag and you
don't exist locally, you get an error.
The -y flag can be used to force YP functionality. -f and -s let you
change your full name and shell (respectively). -f *and* -s let you
change all of your 'account information.'
ypchfn, ypchsh, yppasswd and ypchpass are all links to passwd.
You can now specify separate attributes for selected/not selected
cases individually for each field and also an attr for the form as
a whole so you can now have colored backgrounds for the form and
different coloured fields etc.
Update the example.
Change the copyright to a BSD style one.
Include bteasy, bootsd, sdboot and termcap entries using file2.c

Changed the name from ss_base to ss_sp.
It will read a file on stdin and write it as decimal integers on stdout,

date | file2c 'const char date[] = {' ',0};'

fix the problem.

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.

Use bcopyw() instead of move_up() and move_down(). bcopyw() handles
overlapped copies and should be faster. Actually use bcopy(). bcopy()

If nd->swap_nblks is zero in nfs_mountroot(), then the system

Print a useful message in npxattach() again (delete references to errors
and not the whole message). Don't print "387 emulator" if there is no
emulator in the kernel.
Use %p for pointers in error messages.
Don't clobber the FPU state when there is an FPU exception. Just clear
the exception flags (after saving the flags as before). This allows
debuggers and SIGFPE handlers to look at the full exception state.
SIGFPE handlers should normally return via longjmp(), which restores a
good FPU state (as before). Returning from a SIGFPE handler may leave
the FPU in the wrong state (as before).
Clear the busy latch _after_ clearing the exception flags so that there
is less chance of getting a bogus h/w interrupt for a control operation.
Clear the saved exception status word when the next FPU instruction is
excuted so that it doesn't stick around until the next exception.
Clear the busy latch after fnsave() in npxsave() in case it was set when
npxsave() was called.

- /sys/i386/i386/swapgeneric.c is just plain broke. But fear not, for I
have unbroken it. One thing that swapgeneric.c does is walk through the
list of configured devices searching for a boot device. The only easy
way to accomplish this in 2.0 is to use Garret Wollman's kern_devconf
stuff. *BUT*, the head of the kern_devconf linked list (dc_list) is declared
static in /sys/kern/kern_devconf.c. This means that swapgeneric.c can't
see it at link time. I had to remove the 'static' keyword to get around
this little problem. I hope this doesn't break anything anywhere.
*Furthermore,* there's a small matter of making the call to setconf()
in swapgeneric.c disappear when 'config kernel swap generic' isn't used.
You could change /sbin/config to create a dummy setconf() function in
swapkernel.c, but that seems messy somehow. (It's also someting of an
'it isn't broken, why are you fixing it' situation.) My solution was to
do what the NetBSD people did and put an #ifdef GENERIC around the call
to setconf(). If your kernel is called GENERIC or you define 'options
GENERIC,' then you can use 'config kernel swap generic' and it'll work.
That aside, the upshot is that: a) swapgeneric.c actually works, and
and b) the -a boot flag now works as well. If you boot with -a, as in
"Boot: wd(0,a)/kernel -a" you will be presented with a 'root device?'
prompt after the autoconfig phase, at which point you can specify what
device you want mounted as root. Regrettably, you can't specify an NFS
filesystem. Yet. Three files are affected: /sys/i386/i386/swapgeneric.c,
/sys/i386/i386/autoconf.c and /sys/kern/kern_devconf.c.

- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
has only 8K of shared memory. The only way to have it properly detected
is to zero and test a few bytes of memory just about the first 8K region.
If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.
I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).
- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
the last column, like it should. You don't really notice this unless you
use certain programs that write all the way out to, say, the 80th column,
like VMSmail. Along with a one-line fix for this are some changes to
implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your

However, printing of all segment registers is currently broken.
Don't print "last exception: " before the FPU opcode and pc, etc. The

This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950
SCSI driver for FreeBSD. I started from the 2.0R version and mostly
rewrote it. New features are:
1) New probe algorithm. Old driver read the BIOS region of the adapter
memory and find the copyright string. The problem was in the BIOS itself:
it conflicted with IDE disks. The solution was to unplug it and
make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
to of from the target. It was possible to make it faster,
but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
Some devices seem to be slower (CD-ROMS, some tape drives),
and some seem to be too fast (disks). The driver tests the REQ
deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
priority control.
6) Generic cleanup, after which the driver became much more readable
(at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.

- The -a flag now works just as it does in SunOS: '-a' is actually
handled like a wildcard for all interfaces. 'ifconfig -a' displays
the status of all interfaces, 'ifconfig -a netmask 0xffffff00' sets
the netmask of all interfaces, and so forth. I don't know if many
people really need to be able to set the netmasks of all interfaces
at once, but the SunOS ifconfig seems to allow this, so there you
have it.
- An 'ether_status' function has been added to display the ethernet
address of all ethernet interfaces. Again, as in SunOS, you must
be root in order for this to work. The ethernet address is read
from /dev/kmem using kvm_open() and kvm_read(), much in the same
was as it's done with netstat. If you choose to install ifconfig
set-gid kmem then normal users will be able to see the ethernet
address as well, though this may not be desireable. This feature
requires a small change to the ifconfig Makefile: you need to link
with -lkvm in order to use the kvm_*() functions.

ICRNL doesn't apply to cngetc(). cnputc() unconditionally does the
equivalent of ONLCR; perhaps cngetc() should unconditionally do the
equivalent of ICRNL. Ddb must be checking for CR. Userconfig only
checks for NL. Userconfig works with syscons because pccngetc()

1. The pageout daemon used to block under certain
circumstances, and we needed to add new functionality
that would cause the pageout daemon to block more often.
Now, the pageout daemon mostly just gets rid of pages
and kills processes when the system is out of swap.
The swapping, rss limiting and object cache trimming
have been folded into a new daemon called "vmdaemon".
This new daemon does things that need to be done for
the VM system, but can block. For example, if the
vmdaemon blocks for memory, the pageout daemon
can take care of it. If the pageout daemon had
blocked for memory, it was difficult to handle
the situation correctly (and in some cases, was
impossible).
2. The collapse problem has now been entirely fixed.
It now appears to be impossible to accumulate unnecessary
vm objects. The object collapsing now occurs when ref counts
drop to one (where it is more likely to be more simple anyway
because less pages would be out on disk.) The original
fixes were incomplete in that pathological circumstances
could still be contrived to cause uncontrolled growth
of swap. Also, the old code still, under steady state
conditions, used more swap space than necessary. When
using the new code, users will generally notice a
significant decrease in swap space usage, and theoretically,
the system should be leaving fewer unused pages around
competing for memory.

Subject: Mea culpa -- small fix for netboot fixes
In accordance with the unavoidable principle sof Murphy's Law, I discovered
that the fixes I recently contributed for the netboot code had some small
flaws in them. Two of them were just typos and had no effect on how the
program functioned. The other one was a missing line from the rootopts and
swapopts functions I created in bootmenu.c, which was supposed to initialize
the NFS sotype flag. It defaults to UDP, and you can change it to TCP with
the rootopts or swapopts commands, but then you can't change it back again.
I originally had a line at the top of each function to reinitialize this
flag, but somehow it got lost in the shuffle, probably because I don't
actually have a need for that flag yet.

printf() is inconsistent with the prototype for the library printf() and
gets declared if DIAGNOSTIC is defined because <vm/vm_page.h> includes
<sys/systm.h>.
Notice that the libgcc DOESN'T change number, because there are no
changes.
Also now the gnu2bmake stuff is synchronized again.
I commit this so that others can test too.
You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.
Thanks to Bruce for rounding up our changes to gcc.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.
scsiconf.c:
move the addition of the trailing NUL's out of a then clause, they are also
needed in the else clause for an unknown device.
Alphabetize.
Write all i/o functions in sleep so that we don't use anything from
NetBSD.
Restore the correct type of u_int for ports. This saves a whole cycle
per i/o on 486's.
Change `inline' back to __inline to avoid compiler warnings with
-Wreally-all.
Don't implement bdb() unless BDE_DEBUGGER is defined. Declare bdb_exists
outside the function to avoid hundreds of compiler warnings.
Let the compiler pick the register in asms if possible.
Implement ffs() using inline asm(). gcc provides a slightly different
one. It was broken in gcc-2.4.5 but works now. Declaring a correct
version inline ensures getting a correct version. FreeBSD-1.1.5 has
an slow inline version but FreeBSD-2.0 has a library version (which
probably never gets used).
Do inb() and outb() without using %edx for constant ports below 0x100.
Remove casts to the same type in queue functions.
Declare prototypes for everything implemented i386/*.s and also for
everything that is normally implemented as an inline here (I don't
like the current complete dependency on gcc). Ifdef out the prototypes
that are declared elsewhere. THere should be a separate header to
declare things implemented in i386/*.s, but then it would be harder
to override declarations with inlines.
${UII}
with the current default exception (un)mask. There should be no such
processes unless you change the mask. Someday the mask should be
changed to the IEEE default of everything masked. The npx state
gets saved so that it can be checked and this may have the side effect
of fixing a bug that was reported for 1.1.5. (npx exceptions may
sometimes leak across exits and clobber another process. I can't see
how this can happen.)
Get some missing/wrong declarations from headers now that the headers
have them.
I couldn't find a better way to avoid compiler warnings about
redundant and/or inconsistent declaration of ffs(). I'd like to
be able to declare prototypes in general headers without committing
to implementing them as `static inline' or `extern', but there
seems to be no way to do this with gcc-2.6.1. E.g.,
int foo(void);
static __inline int foo(void) { return 1; }
causes a warning about the linkage mismatch, while the opposite
order causes a warning about the redundant declaration.
the following.
Move declarations to and from <machine/segments.h>. Make segment stuff
static if possible.
Remove unused (although initialized) global variables _default_ldt,
currentldt, _gsel_tss (rename the latter to the auto variable
gtel_tss).
Use "correct" and consistent types for interrupt handlers.
Remove a mailing address from the code.
Fix type mismatches found by adding prototypes.
Partly support BDE_DEBUGGER. Still broken by conflict with APM. Does
nothing if BDE_DEBUGGER is not defined.
Clean up prototypes and data declarations. Declare most of the segment
functions that are implemented in support.s. Make data private in
machdep.c if possible.
Parenthesize expressions in macros properly!
${Uniformize idempotency ifdef}.
to avoid compiler warnings.
Clean up prototypes: alphabetize; don't use redundant `extern' or
meaningless `extern inline'.
Uniformize idempotency ifdef.
(These functions are implemented in assembler so the compiler can't
check the declarations.)
Clean up prototypes: restore CSRG's alphabetical order, arg names in
prototypes, formatting to fit in 80 columns
Declare a complete prototype for the function pointer *ifa_rtrequest.
radix.h:
Declare a complete prototype for the function pointer *rnh_walktree
and for the function rn_walktree.
Uniformize idempotency ifdef.
Disable the bogus declaration of pmap_bootstrap(). Since its arg list
is machine-dependent, it must be declared in a machine-dependent header.
vm_page.h:
Change `inline' to `__inline' and old-style function parameter lists for
inlined functions to new-style.
`inline' and old-style function parameter lists should never be used in
system headers, even in very machine-dependent ones, because they cause
warnings from gcc -Wreally-all.
$(DESTDIR)/$(LIBDIR) (I need SHLIBDIR. The / was a bug and the
$(...) style was inconsistent.)
Install ordinary libraries in ${DESTDIR}${LIBDIR} instead of in
$(DESTDIR)/$(LIBDIR).
Change remaining $(...) to ${...}.
Define SHLIBDIR?= ${LIBDIR} and install shared libraries in
${DESTDIR}${SHLIBDIR} instead of in ${DESTDIR}${LIBDIR}.
SHLIBDIR may be defined in /etc/make.conf to override the
default of /usr/lib (I use /lib). Other changes are required
for non-default shared library directories to actually work
(ld* and crtso have too many hard-coded paths).

more like binaries. This is hard to do using a general rules because
the natural `.sh:' rule has a null suffix and null suffixes are broken.
(With 1.1.5's make they sometimes work and sometimes cause core dumps.
2.0's make has a botched fixed and they never work.)
RANTOUCH may be defined in /etc/make.conf as
`${ECHO} skipping ${RANLIB} -t' to help stop `make install' from
changing the timestamps on unchanged libraries, thus making the
uninstalled binaries appear to be out of date... Other changes
are required to stop install from clobbering the timestamps.
Comment about missing libraries for LIBDES, LIBKDB, LIBKRB, LIBMP, LIBPC
and LIBPLOT.
Don't define LIBDBM since it was replaced by db in libc.
Remove duplication. ${DESTDIR}/usr/lib/... gives /usr/lib/... even when
DESTDIR is not defined.
get truncated to LONG_MAX. Don't lobotomize the merged library source.
Make all private data static.
Use int_parms for the i/o "address" since the "address" is really a number
and is represented as an int.
Add command `flags' to allow changing device flags.
Fix scrolling of device listing. Only scrolling of the current devtab
was controlled. Reprint the header after scrolling.
Rename commands and change strings to match their config(8) keywords:
io -> port
IOaddr -> port
mem -> iomem (abbreviation is io :-()
MemAddr -> iomem

Don't use NULL for ASCII NUL.
Call strtoul() with base 0 for both numbers and addresses so that input
is consistent and hex and octal can be used for numbers.
Fix entry of irq number. Check the range at no extra cost. It wasn't
possible to enter irq -1.
Format device listing better. Large numbers (such as 0xffffffff for the
GENERIC lpt0 port) messed up the formatting.
Show the unit number in the device listing. Comment about the fields
that aren't shown.
fault was at offset 0 in the object. This resulted in more overhead but
was othewise benign. Added incore() check in vnode_pager_has_page()
to work around a problem with LFS...other than slightly higher overhead,
this change has no affect on UFS.
put the stuff into the right "distribution". As default things end up
in "bindist".
Normal (ie: most) makefiles know naught of this.
More commits will follow, which will direct various parts of the tree

Some of the grief of being release-engineer is supposed to go away with this.

of the 1.1.5 driver, a recent version of the NetBSD driver, Andres'
transmission start threshold code, and all other relavent changes to the driver
since it was brought into 2.0. The multicast support from NetBSD has not be

robust enough to be included in the GENERIC kernel.

This attempts to make the installion a little less grating by not

It can't be set to "" all the time since then small dialogs appearing
