Unfortunately, it would suggest the _opposite_ behavior: setsid() from a process run by an interactive shell should fail. Too bad you didn't provide a complete description of the system calls made by your program, or direct evidence (say, the output of ps -j) of the results of running it in the two cases. As is, my current guess is that you're misreading the 'ps' output and confusing the concepts of process-group leader and session leader. Philip Guenther

I've tried the same using GDBM_File from the perl in-tree.
Even if regress fails and something seems wrong it compiles... maybe
enough for someone else to get it working.
Other things not taken care of: gdbm.t uses Config.pm to check GDM_Files
existance which can't work as Config.pm gets setup with base perl.
I've worked around this patching the gdbm.t @INC with blib/lib but then
the tests fail with a hand full of unknown symbols...
And i don't know if this kind of Makefile is even accepted... may need
some more polishing.
Makefile attached,
good luck and regards

Thank you Jonathan for the link but I've already read this thread and
the bug report yesterday. It's apparently a different problem for me.
I don't know if I must initialize a bug report for my specific kernel
crash (panic: can't deal with not-all-lapics interrupt yet!). Some
changes have been made on /usr/src/sys/arch/i386/i386/mpbios.c since
3.9 was released, but it's only for the amd64 architecture.
Here an excerpt from mpbios.c:
[...]
if (entry->type == MPS_MCT_IOINT) {
sc = ioapic_find(id);
if (sc == NULL) {
printf("mpbios: can't find ioapic %d\n", id);
return;
}
mpi->ioapic = sc;
mpi->ioapic_pin = pin;
altmpi = sc->sc_pins[pin].ip_map;
if (altmpi != NULL) {
if ((altmpi->type != type) ||
(altmpi->flags != flags)) {
printf(
"%s: conflicting map entries for pin %d\n",

}
} else {

}
} else {

Strange 3.9 lock-up
Hi [EMAIL PROTECTED] As I have mentioned before my 3.9-box locks up in a strange way: 1. it is pingable 2. syn-scan gives out open ports 3. but those ports are not accessable(for ex. I can not drop in into this box via ssh or browse port 80) This is a second lock-up after upgrade, box stays up in max 10-12 days. Any ideas what is going on? Box was upgraded from 3.7 to 3.9 . It was stable with 3.7 . It is 3.9-stable (cvsup:ed and recompiled after first lock-up). I'v done complete clean up after upgrade, before compiling new ports. Box is Dell PowerEdge 1850 with 2Gb ECC RAM, 2GHz Xeon, 2x36 Gb SCSI. Here is a tcpdump (this box actually sending packates back! so it can't be a crach): 12:06:08.750761 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: SWE 4202843211:4202843211(0) win 16384 (DF) 12:06:08.769546 unixconn.com.ssh > blowfish.home.unixconn.com.17771: SE 2739826010:2739826010(0) ack 4202843212 win 16384 [tos 0x70] 12:06:08.769628 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: . ack 1 win 16384 (DF) (CTRL-C pushed) 12:11:09.309092 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: F 1:1(0) ack 1 win 16384 (DF) 12:11:10.806973 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:11:13.806975 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:11:19.806972 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:11:31.806987 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:11:55.806988 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:12:43.806989 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:13:47.806983 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:14:51.806986 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:15:55.806987 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:16:59.806984 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:18:03.957345 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF) 12:19:07.957346 blowfish.home.unixconn.com.17771 > unixconn.com.ssh: FW 1:1(0) ack 1 win 16384 (DF)

I was migrating 16GB of mailboxes to Cyrus using deliver, without limiting the number of lmtpd processes. This put a lot of stress on the box and it locked-up. The first time I tried the migration, the machine panicked with a "uvm_mapent_alloc: out of static map entries" message. I couldn't get a backtrace because it hadn't a serial console attached (now it has). But the subsequent ones it didn't crash, only showed the same behavior that has been described here. Connections dropped but responds to ping, no keyboard typping response. Finally i limited the number of lmtpd processes and I could complete the migration. This machine it's in a testing stage by now, and I can reproduce the problem in an hour or two Best regards, Samuel
strange kernel driver & application behaviour
Hello,
I'm trying since 3.8 release to figure out what's
wrong on my desktop computer. Now I'm running 3.9 and
I still have this strange behaviour (dmesg attached to
the end of this text block).
The issue is related to the sound applications. The
hardware is a VIA8233 AC97 + ICEnsemble ICE1232. I
started with 2 multimedia applications:
mplayer-1.0pre7p15
xmms-1.2.10p6 (xmms-mp3-1.2.10p6)
XMMS is playing almost ok, because some pitches and
chunks are audible. This issue was understandable when
I found out on the web that this hardware is locked on
a 48000 Hz rate, so you must use this sampling rate.
XMMS is not able to do this sampling, so I tested it
without this feature. The mp3 is played, but in the
moment I receive 'auvia0: codec invalid' in the
console, the volume jumps up. If I check the mixerctl
-a setting, I can see that outputs.master=255,255 and
inputs.dac=255,255 , even they were selected on the
average values before. If i turn them back, after a
while they jump again on the maximum values.
MPlayer has the option to do a sample rate on 48000
Hz. I use it, the sound in not a garbage, but the
behavior is the same like XMMS: the two mixerctl
settings are set to maximum at the first report of
'auvia0: codec invalid' - blue background text
reported in the console . At the second report of the
same text, the sound is gone. I checked and I saw
another two mixerctl setting modified:
outputs.master.mute=on (it was off) and
inputs.dac.mute=on (it was off, too).
On both applications, I set the mixerctl settings
back, but they are changed after a while , like I said
before.
I installed another well known decoder:
mpg123-0.59rp4
I started this command line application with sample
rate set to 48000 Hz and everything is ok. That text
message is not reported in the console, and the sound
is ok.
I found just 2 people complaining about this on the
web, but also many own this hardware and they don't
reports such behaviours. I even changed some values in
source code (TIMEOUT define in
/usr/src/sys/dev/pci/auvia.c ) but no luck. I don't
know what's wrong, maybe a BIOS PCI setting. There is
also a comment on the source code of OpenBSD related
to this error message, dated back in 3.2 release.
If anyone has a hint, please sent it to me. I'm not
sure if this is because of driver or the application.
Thanks

Result matches your description precisely (though this is likely not the only reason such a thing can happen). It isn't a crash, just a really nasty hang.

How to make fsck run faster?
Hello, I have a 3.8 machine with millions of files. The exact number of files varies a lot but it's always more than 5M. One day I had a power failure and I had to wait for fsck to complete on reboot. Fsck took more than two hours! At that time there were 8,8M files on the drive. Is there any way to make fsck go faster? The machine is AMD Athlon 1700+ with 200G Seagate Barracuda on SATA slot. Unfortunately I cannot get dmesg at this point but I don't think that's necessary. Kernel is 3.8 GENERIC and there is one large ffs partition on the SATA disc, roughly the size of 180G. Most of the files (approximately 90%) are hardlinks. Disc usage is somewhere between 30G and 170G. Any pointers will be appreciated, thanks in advance! Antti Harri

Wow, what an annoying set of coding conventions you use. The best
part is, the bug is in your use of one of them: use of unnamed bit
flags with particular flags being stored in _different_bits_ in
different parts of the code. (i.e., the "do setsid()" flag is 4 in
main but 2 in the above. Using the same values and defining symbolic
names would have kept this problem from occuring. Not trying to be
too clever would have helped too.
So, please consider the above code and then think _really_ hard about
the code that determines the value of 'f' in that call:
...
case 's' : f |= 2, f |= 4; break;
case 'p' : f |= 2, f &= ~4; break;
...
if (!r) r = do_sid(f & 6 >> 1);
That last line contains the bug, but the _source_ of the bug is either
the lack of symbolic constants or your decision to use bitflags at all
instead of just putting the flags in separate variables.

nope, you can still likely use multiple partitions. Break your backup
job into smaller chunks, put each chunk on its own partition. Or put
each machine on its own partition. Or ...
Quit "thinking big". Design your project right, it can work. And "What
happens when I trip over the power cord" is part of designing the
project right.
I wonder if using database as an extra layer
would help? I would need a wrapper but that
wouldn't be a problem.
oh, gee, let's make things more complicated. Thank you, no. ('course,
that's my general reaction when someone suggests using a database to
"improve" something... I have NO idea what you are suggesting, but I'm
pretty sure I won't like it.)
BTW: Yes, the dmesg could very well have helped. If your disks were not
being handled properly or you had insufficient RAM, you can have
HORRIBLE problems with fsck performance, adding to your fsck time by a
non-trivial multiple. Your times sound excessive to me, but then, I
don't think I have that many files on a single partition.
One idea which has been suggested is to use softupdates, and simply
"force" mounting of the volume at boot, and periodically, fsck the thing
on your schedule, to reclaim lost disk space. Yes, when you do run the
fsck, you will spend a lot of time waiting for it, but you will be able
to schedule it.
Keep in mind, partitions need not all be mounted in /etc/fstab, they can
be manually mounted "later" in rc.local. Why does your backup machine
have to boot "fast"? (I got one with way too little RAM, it needs to
use swap to fsck, but that's ok...I'm not in a hurry for this machine to
come up). Doing something else with it? Ok, just put the backup
partition as noauto in /etc/fstab, and fsck and mount (or just
force-mount) the partition in /etc/rc.local. Now, whatever it was that
was bothering you about booting so slowly is up quickly, and the backup
partition will get mounted in due time.

Restore the data into /home Is it really that easy to expand a partition? Have I missed something here? Is it a safer/simpler bit to wipe the disk and start again? no, that's basically it. Other "easy" alternatives would be to reassign your /home partition to be your /var partition, and copy on the fly, reset fstab, and reboot. If you wish to do this by remote, you will pretty much need to use this option, as when you unmount /var, you will probably piss off ssh and lose your connection to the box. If you don't want to use all of home for this, just delete home, make a new partition for /var, copy the data to it, reassign in fstab, reboot. Yes, you may end up "losing" your old /var, but its obviously a big disk, you probably won't miss it. Or you can use it for something else later. BTW: This is exactly the reason I keep saying, "Don't allocate all your disk unless you really need it!", being able to copy/grow into unused space is easier than moving/rebuilding. Safer/simpler to wipe/reload? Not if you have a good backup. If something goes wrong, you are prepared to do this anyway, might as well have some fun learning stuff. :) Nick.

Re: Boot panic with bsd.mp on a Compaq ProLiant 2500
I happened to read this as I was on my way out of the office for the
week (yay for vacation, and a paid one at that) I don't recall the exact
error, but on 3 different SMP slot 1 machines, bsd.mp under 3.9
complains about apic, and dies. PS shows swapper as the only thing
active. Will look more into it on Friday when I get back, and post what
I find. Although, the thought of going back a version or two seems like
it might work, as I know I've had 3.7 or 3.8 working on at least one of
my dual slot 1 machines...
Hope that helps at least a little bit,
Nick

I've got 3.9 running on a DL380 without trouble (GENERIC.MP), and that
should be the same mainboard as an ML370. Make sure you've got all
current firmware on the box, and try various "OS" settings until one
works properly (including "Other"). Incorrect settings will probably
result in a crash on boot, or only one CPU.
Today, I've try different "OS" settings in the BIOS like UnixWare,
Solaris, Windows (2000) and they all do a kernel panic with bsd.mp. I
have the "trace", "ps" and "show registers" for them if somebody want to
see the details.
"Unix with large disk geometry" and "Other" OS types only detect one
processor with the "Inspect" Compaq tool.
"Other" OS type does not panic the kernel with bsd.mp, but only one
processor is detected:

I've "googling" for some time now, but I can't find a definitive answer

Thank you Steve and Nick for your feedback.

Until you come up with a simple (let's say less than 10 lines) piece
of code to demonstrate the porblem you're seeing, my conclusion is the
bug is hiding in your code.

Another thing is to move to larger block and fragment sizes. Depending on the size distribution of your files, this will waste some space, though. I tested 1TB filesystems with varying block and fragment sizes, and it is really nice to see the speedup of newfs anf fsck. -Otto
