- It's int main(argc, argv), not void main(argc, argv), gosh darn it.
- If a child receives a SIGTERM, it will call the terminate() function
and end up doing the shutdown procedurs that should really only be
done by the parent. Set the SIGTERM behavior back to SIG_DLT in the
child after fork()ing.
- If the parent fails to read data back from the child because the
child has exited, it will call rpc_received() with bogus tdata that
can cause the parent to SEGV. Make handle_children() detect this
condition correctly and handle it sanely.

- Today I asked myself: "Self, you wrote this nifty async resolver
that does a great job handling delayed replies to clients using
the UDP transport, and the yplib code in libc always uses UDP
(except for yp_all()). But what if some dork makes a DNS lookup using
TCP?" Being the only dork on hand at the time, I tried it and was
enlightened. As I suspected, my transaction ID frobbing hacks cause
fireworks if called on a TCP transport handle (duh: the structures
are different). Fix: check the type of socket in xprt->xp_sock using
getsockopt() and don't use svcudp_get_xid() and svcudp_set_xid() for
anything except SOCK_DGRAM sockets. (Since accept() gives you a
new socket for each connection, the transaction ID munging isn't
needed for TCP anyway.)
- yp_dblookup.c: Create non-DB specific database access functions.
Using these allows access to the underlying database functions without
needing explicit knowledge of Berkeley DB. (These are used only
when DB_CACHE is #defined. Other programs that use the non-caching
functions (yp_mkdb, ypxfr, yppush, rpc.yppasswdd) shouldn't notice
the difference.)
- yp_dnslookup: Implement async DNS lookups. We send our own DNS
requests using UDP and put the request in a queue. When the response
arrives, we use the ID in the header to find the corresponsing queue
entry and then send the response to the client. We can go about our
business and handle other YP requests in the meantime. This way, we
can deal with time consuming DNS requests without blocking and without
forking.
- yp_server.c: Convert to using new non-DB-specific database access
functions. This simplifies the code a bit and removes the need for
this module to know anything about Berkeley DB. Also convert the
ypproc_match_2_svc() function to use the async DNS lookup routines.
- yp_main.c: tweak yp_svc_run() to add the resolver socket to the
set of descriptors monitored in the select() loop. Also add a
timeout to select(); we may get stale DNS requests stuck in the
queue which we want to invalidate after a while. If the timeout
hits, we decrement the ttl on all pending DNS requests and nuke
those requests that aren't handled before ttl hits zero.
- yp_extern.h: Add prototypes for new stuff.
- yp_svc_udp.c (new file): The async resolver code needs to be able
to rummage around inside the RPC UDP transport handle in order to
work correcty. There's basically one transport handle, and each time
a request comes in, the transaction ID in the handle is changed.
This means that if we queue a DNS request, then we handle some other
unrelated requests, we will be unable to send the DNS response because
the transaction ID and remote address of the client that made the DNS
request will have been lost. What we need to do is save the client
address and transaction ID in the queue entry for the DNS request,
then put the transaction ID and address back in the transport handle
when we're ready to reply. (And then we have to undo the change so
as not to confuse any other part of the server.) The trouble is that
the transaction ID is hidden in an opaque part of the transport handle,
and only the code in the svc_udp module in the RPC library knows how
to handle it. This file contains a couple of functions that let us
read and set the transaction ID in spite of this. This is really a
dirty trick and I should be taken out and shot for even thinking about
it, but there's no other way to get this stuff to work.

_without_ using fork().
The problem with YPPROC_ALL is that it transmits an entire map through
a TCP pipe as the result of a single RPC call. First of all, this requires
certain hackery in the XDR filter. Second, if the map being sent is
large, the server can end up spending lots of time in the XDR filter
sending to just the one client, while requests for other clients will
go unanswered.
My original solution for this was to fork() the request into a child
process which terminates after the map has been transmitted (or the
transfer is interrupted due to an error). This leaves the parent free
to handle other requests. But this solution is kind of lame: fork()
is relatively expensive, and we have to keep a cap on the number of
child processes to keep from swamping the system.
What we do now is grab control of the service transport handle and XDR
handle from the RPC library and send the records one at a time ourselves
instead of letting the RPC library do it. We send a record, then go
back to the svc_run() loop and select() on the socket. If select() says
we can still write data, we send the next record. Then we call
svc_getreqset() and handle other RPCs and loop around again. This way,
we can handle other RPCs between records.
We manage multiple YPPROC_ALL requests using a circular queue. When a
request is done, we dequeue it and destroy the handle. We also tag
each request with a ttl which is decremented whevever we run the queue
and a handle isn't serviced. This lets us nuke requests that have sat
idle for too long (if we didn't do this, we might run out of socket
descriptors.)
Now all I have to do is come up with an async resolver, and ypserv
won't need to fork() at all. :)

throrough shakedown before the final cutoff date.

Fenner was kind enough to point out the error of my ways. This incorporates
diffs from him which:
- Keep everything in network order.
- Log the booted ether & ip address, instead of my address on that net
- change several exit()'s to return()'s, so that rarpd continues running
even if it thinks it's in a weird state.
One small tweak by me: in rarp_bootable(), we have to make sure to
construct 'ipname' in host byte order (if we don't, we have to
specify /tftpboot/<remote IP in hex> with <remote IP in hex> in
network byte order, which is confusing).

- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results
were just confusing most of the time.
- The program no longer contains a pre-compiled list of timezones
(compiled by groveling through the tzdata source files for comments
starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file
supplied with current versions of the timezone data files, to determine
the list at run time. (It also requires the ISO 3166 table I
committed some months ago.)
AS A RESULT, this program will NOT work until the new timezone data files
are committed (should happen sometime soon).
This includes the following changes:
- Support for poking ARP entries into the local table is now built
in, so the arptab.c module I hacked together is no longer needed.
- rarp_process() and rarp_reply() now accept a len argument which is
passed down from rarp_loop() which tells rarp_reply() exactly how
long the original RARP frame was. (Usually, it's 60 bytes, which is
the minimum.) Previously, the length was calculated using the sum
of sizeof(struct ether_header) + sizeof(struct ether_arp) (plus the
ethernet frame header, I think). The result was a total packet
length of 42 bytes. Now, rarp_reply() sends out packets that are
the same size as those it recieves (60 bytes). This agrees with the
behavior of rarpd on SunOS (as observed with tcpdump). The unused
extra bytes are zeroed.

syslogd as well.
- if the child process exited early (eg: could not bind to the socket),
the boot process would hang for 30 seconds. The parent was not noticing
that the child had exited. (my fault)
- when writing to tty devices, instead of treating them like files that
need \r\n instead of \n, actually use ttymsg() which has specific code
intended to write to potentially blocking ttys safely. I had a machine
lock up last night because /dev/console on a serial port got flow control
blocked. Setting comcontrol drainwait fixed everything but syslogd which
was going into a spin trying to write to the console and completely
ignoreing everything else.

anybody knows how to get ``192.168.0.1:/swap.192.168.0.3'' instead,
please step forward!
This fixes the kernel panic when propagating userconfig changes to
arbitrary kernels.
Remove obsoleted `#include <tcl.h>' added a few <stdio.h> where
necessary.
Fix getting scsi bus information from an -incore kernel.
Turned on SAVE_USERCONFIG by default.
required. a core is not dumped at first connecting time and
dumped at second or third time. (patch I)
2. A routine for "show route" refers out of allocated space.
Values pointed by "lp" should be read as CHAR, I think.
there is also no free() for disallocation. (patch II)
Here is also a patch for an improvement: In current imprementation,
even if PPP connection is disconnected by time out, prompt of
interactive mode does not change from "PPP>" to "ppp>" to
indicate the disconnection on a terminal.
So I modified the code to do that. (patch III)

For me, more often than not, the backgrounded syslogd daemon is not
yet ready to process log messages before other things (such as named)
want to log a heap of them. It seems that it's the O_SYNC writes of
the stuff coming in from /dev/klog that's the slowdown.
Anyway, instead of using the libc daemon, roll a modified version. This
one has a timeout. The child will wait for either the timeout to expire
or the child process to signal it to let it know that it's "ready" and
the /dev/log socket is set up and active, so it's safe to continue the
boot. It adds a small fraction of a second pause to the boot time, but on
the other hand the overall boot time is *quicker* since the disk is not
being thrashed while the log messages are getting written out synchronously
one by one while other daemons are loading in parallel.
The timeout is in case the child segfaults or something before becoming
fully operational.
SLIP/PPP devices, putting them before the others in the network device

2. Change "Other" to "URL" so as not to conflict with the keyboard accellerator
for the "OK" button in FTP site selection menu.
3. Detect the NULL last symbol in the name list and initialize the other
members correctly.
First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):
% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").
