Re: src/games bikeshed time.
Below is my proposed patch to primes(6) and factor(6) which I plan
to commit in one go since the changes are somewhat inter-dependent.
Feedback is welcomed. I'm in the process of fixing the manual.
Merge changes from NetBSD and perform some cleaning up.
primes:
const-correctness and removal of wacky casting (from NetBSD);
move declarations of external tables into primes.h instead
of repeating them in primes.c and factor.c. Still limited to
ULONG_MAX though.
factor:
style fixes (#include ordering, ANSI functions, const-correctness,
staticisation -- all but the latter from NetBSD); remove bogus comment;
fix usage() exit value; and the biggie: if OpenSSL is available,
use bignums using clever code from NetBSD. I have cleaned the latter
up somewhat so that it supports FreeBSD's -h feature and doesn't
introduce regressions for N = 2^31 in the non-OpenSSL case.
Tony.

So how does it implement ETRN and ATRN? They're both sufficiently unimportant not to make it worth complicating the MTA to optimise them. Exim lets you specify a shell command that is run in order to implement these SMTP commands, so it's up to you whether this involves a queue run (with exim -R) or not. For example, you might route incoming mail to a dial-up host and use the appendfile transport to dump it in a directory with use_bsmtp, and cause ETRN commands to run over that directory. (Although the latter requires extra code.) I'm interested that you think ETRN is important, because to me it seems the wrong solution given POP with the *ENV extension, or decent IMAP.

Re: {a}sync updates (was Re: make install trick)
I have noticed similarly odd behaviour from softupdates during heavy IO load, where something is creating lots of little files or directories and not much else is happening. Using `vmstat 1` I can see that softupdates isn't very good at evening out the IO rate over time: there's a roughly sinusoidal back-and-forth between frantic disk thrashing (lots of TPS) and lots of syscall activity. Visible progress is correspondingly uneven. For example, the `vmstat 1` output while the script for i in `jot 256` do for j in `jot 256` do mkdir -p $i/$j done done is running is appended below. Behaviour is much smoother during an `rm -r *` of the resulting directory tree.

Re: NFS Patch #8 for current available - new TCP fixes
Matthew Dillon dil...@apollo.backplane.com wrote: (fanfair!) :-) NFS attempts to realign packet buffers and trods all over the underlying mbufs. For TCP connections, several RPC's may be present in an mbuf chain. The realignment of one of them may destroy the others. This does not occur with UDP because each UDP packet contains only a single rpc. Packet buffers may be unaligned for a number of reasons. The main reason is due to the 14 byte MAC header on the ethernet frame. This causes the remainder of the packet - the ip payload - to NOT be 4-byte aligned. We're planning to try replacing some Solaris web servers with FreeBSD machines in the near future. The documents are on a read-only NFS filestore connected to the web servers with CDDI.

booting systems with lots of memory
We have a Quad 400MHz Xeon on evaluation here and we're trying to get
a large memory configuration working. The machine is running a recent
3.1-STABLE with the kva patch from -CURRENT (appended below). When we
have a working system with 1GB of RAM we'll increase it to 3GB of RAM
and see how it runs.
The boot blocks are from 3.0-RELEASE and they will boot the old a.out
kernel via /boot/loader quite happily. We haven't yet managed to boot
an ELF kernel, though (but we haven't tried to boot an unpatched one).
It's also somewhat painful to debug because the machine is miles away
and its serial console is causing trouble.
Are there any obvious things we have missed? I assume the kernel load
address is read by /boot/loader from the kernel's ELF header, so that
a recent loader can cope. I also assume that the patch included below
tweaks all of the required knobs.
Tony.

(I'm reluctant to completely hose the machine...) AFAIK it should. Not sure myself to be honest :( Well, I took the plunge and booted with the new loader and the box came back fine, so I'm less worried about booting old kernels. Tomorrow we try it with 3GB of RAM :-) Also, w.r.t. the serial console problems, can I set the baud rate early in the boot sequence, and if so, how? The console works once getty puts up a login prompt but not before then, and I get a whole lot of garbage that I guess is baud barf (I wouldn't know for sure -- too much of a newbie). Don't know. I don't use serial console. Did you check http://www.freebsd.org/~msmith/FTL/bootstrap.txt for any info? I did, yes. Most of that is now in the loader(8) manual. I tried changing /boot.config to contain /boot/loader -h which improved matters. There's still some garbage but it's fine after FreeBSD BOOT @ 0x1: 634/15360 k of memory, serial console. We suspect a BIOS that's being too damn clever for its own good.

I just remembered that MNT_UNION occurs in another file which on
investigation turned out to be amongst the unionfs code that was
moved. It should be removed so that the code isn't run twice when
unionfs is enabled. Sorry for missing it the first time round! I also
tidied up the vfs_syscalls patch a bit.

I don't know for sure, but I suspect that this is the only case in which union mounts are designed to work. I was led to believe (last time I read the code) that any directory should be ok for a union mount I was led to believe the same by the manual: union Causes the namespace at the mount point to appear as the union of the mounted filesystem root and the existing di- rectory. Lookups will be done in the mounted filesystem first. If those operations fail due to a non-existent file the underlying directory is then accessed. All cre- ates are done in the mounted filesystem. I did a brief experiment on the 3.0-RELEASE machine as follows: # mount /dev/da0s1a on / (local, writes: sync 1163 async 18438) procfs on /proc (local) /dev/da0s1e on /usr (local, writes: sync 363 async 41653) /dev/da1s1e on /www/da1 (local, writes: sync 12 async 38) # ls da1/subdir this_is_da1 # mount -o union /dev/da2s1e da1/subdir # ls da1/subdir this_is_da1 this_is_da2 # So that machine is happy enough with union nounts on top of subdirectories.

The odd thing is that AFAICS no-one has made significant changes to
this code.
i just experienced the above today while trying diskless, and while
ls only seems to return the entries for the topmost directory, files
are accessible if you know the name. no idea if this is of any help.
This is exactly the right pointer, thanks! The problem appears to be
the change between revs 1.108 and 1.109 of sys/kern/vfs_syscalls.c. A
couple of (very similar) blocks of code related to `mount -o union`
seem to have been mixed up with some code related to `mount -t union`
and therefore removed. It's a shame that the two things get confused
so much. I originally missed vfs_syscalls.c because a `find
/usr/src/sys | xargs grep MNT_UNION` on 3.1 didn't show it. Replacing
the errant code fixes the problem. Here's a patch against 1.112.2.1.

mount -o union broken recently?
I have been experimenting with union mounts today with a recent -stable (cvsupped yesterday), and I haven't had much luck. Because cvsup likes to obliterate local changes, I thought it would be convenient to keep the altered files on a separate filesystem and use a union mount to overlay them on the upstream source when I compile things.

Re: adding DHCP client to src/contrib/
Mike Smith m...@smith.net.au wrote: I've got a machine on the DHCP required network with two NICs. Currently I'm only using one of them and thus don't have it listed in ``network_interfaces''. So it just happily sits there. IMHO we shouldn't try to dhcp configure it. It will just fill up logs as it continues to try to get a lease which it can't. In a situation like that, you would just tune the dhcp client not to ask for a lease on that interface. You know you've done something silly; there's a mechanism to stop it breaking things. What more could you ask for? POLA. Currently, an interface that isn't mentioned isn't configured at all. Changing that isn't kind. Perhaps having a variable in rc.conf that lists the interfaces to be configured with DHCP would be better? (As opposed to the statically configured interfaces.)

I'd suggest that there's a vast difference in the intended audience of the code containing the above comment and FreeBSD. Not to mention a 20+ year gap in time. Whilst the official codebase may be under the control of a select group of committers, the code should be capable of being understood by anyone who is reasonably proficient with C. If understanding the kernel requires that you be a guru-level expert in C, then people won't bother. FreeBSD will wind up being a small collection of people trying to outdo each other in obtuseness. Don't be silly. FreeBSD is much more complicated than V6 for a whole lot of reasons that are independent of who gets to read the code and who gets to change it. Just as a starting point, the kernel has about a million lines of code compared to V6's ten thousand lines; Lions' comment about 1 lines being a comfortable amount of code for one person to understand comes to mind. The x86 architecture is vastly more complicated and baroque than the PDP11. We now have paging and networking and SMP and a whole lot of other sophisticated stuff that were completely beyond V6. The magic of swtch() is written in assembler, not C. On the other hand, what we have that the early Unix community didn't have is the Internet. We can collaborate with email, we can browse the code history with CVS, and generally benefit from a far greater level of support.

This is a strawman. The original expression is perfectly fine (by my
rules). One could make a case for:
if ((t % u) - (n % u) d % u)
Am I a heretic for suggesting this?
if (t%u - n%u d%u)
Grouping without brackets!
