strange behaviour with /sbin/init and serial console
Hello,
with the following patch on /sbin/init, I have two different behaviours
depending on the console type (on a i386/32 PC) :
- on a video console, I see the expected two messages,
- on a serial console, the messages are not displayed (init silently finishes
its job and gets to start /etc/rc and everything)
I assume that the writev system call is implemented in
src/sys/kern/tty_cons.c::cnwrite(), but I could not parse the code to find an
explanation.
any taker ?

Before then, and after 1.128, some cases worked as intended if not perfectly: - regular files: file systems still set va_blksize to their idea of the best i/o size (normally to the file system block size, which is normally larger than PAGE_SIZE and probably better in all cases) and this was used here. However, for regular files, the fs block size and the application's i/o size are almost irrelevant in most cases due to vfs clustering. Most large i/o's are done physically with the cluster size (which due to a related bug suite ends up being hard-coded to MAXPHYS (128K) at a minor cost when this is different from the best size). - disk files: non-broken device drivers set si_iosize_best to their idea of the best i/o size (normally to the max i/o size, which is normally better than PAGE_SIZE) and this was used here. The bogus default of BLKDEV_IOSIZE was used for broken drivers (this is bogus because it was for the buffer cache implementation for block devices which no longer exist and was too small for them anyway). - non-disk character-special files: the default of PAGE_SIZE was used. The comment about defaulting to PAGE_SIZE was added in 1.128 and is mainly for this case. Now the comment is nonsense since the value is fixed, not a default. - other file types (fifos, pipes, sockets, ...): these got the default of PAGE_SIZE too. In rev.1.1, st_blksize was set to va_blksize in all cases. So file systems were supposed to set va_blksize reasonably in all cases, but this is not easy and they did nothing good except for regular files. agreed, anyway the comment by phk about using ioctl(DIOCGSECTORSIZE) applies. Versions between 1.2 and 1.127 did weird things like defaulting to DFLTPHYS (64K) for most cdevs but using a small size like BLKDEV_IOSIZE (2K) for disks. This gave nonsense like 64K buffers for slow tty devices (keyboards) and 2K buffers for fast disks. At least for programs that trust st_blksize o be reasonable. Fortunately, st_blsize is rarely used... the net effect of this change is to decrease the block buffer size used in libc/stdio from 16 kbytes (derived from the underlying ufs partition) to PAGE_SIZE ==4 kbytes (fixed value), and consequently the I/O bandwidth is lowered (this is on a slow Flash). ... except it is used by stdio. (Another mess here is that stdio mostly doesn't use its own BUFSIZ. It trusts st_blksize if fstat() to determine This is indeed what I saw, meandering between the libc and the vfs part of the kernel. In fact, I was essentially wondering if st_blksize was used *elsewhere*, and bumping the value could break some memory allocation ... st_blksize works. Of course, the existence of BUFSIZ is a related historical mistake -- no fixed size can work best for all cases. But when BUFSIZ is used, it is an even worse default than PAGE_SIZE.) (as it is even smaller ?) It's interesting that you can see the difference. Clustering is especially good for hiding slowness on slow devices. Maybe you are using a configuration that makes clustering ineffective. Mounting the file system with -o sync or equivalently, doing a sync after every (too-small) write would do it. Otherwise, writes are normally delated until the next cluster boundary. My use case is for small (buffered) writes to a file between 4 kbytes and 16 16 kbytes. For example, writing a 16-kbyte file with a st_blksize of 4k is twice as slow as with 16k (220 ms compared to 110). The penalty is less for 8k-byte (105 ms vs 66). I have patched the kernel with a larger, fixed value (simply 4*PAGE_SIZE, to revert to the block size previoulsly used), and the kernel and world seem to be running fine. Seeing the XXX coment above, I'm a bit worried about keeping this new st_blksize value. are there any drawbacks with running with this bigger buffer size value ? Mostly it doesn't matter, since buffering (clustering) hides the differences. (as seen before, mostly) Without clustering, 16K is a much better default for disks than 4K, though not as good as the non-default va_blksize for regular files. Newer disks might prefer 32K or 64k, but then the fs block size should also be increased from 16K. Otherwise, increasing the block size usually reduces performance, by thrashing caches or increasing latencies. With modern cache sizes and disk

Keeping an eye on the text console while in X11 ?
Hello, [long message] I'm chasing strange freezes on my work PC, with a recent -Current (5.2-SNAP from 01/30). The machine is NEC PeeCee, using a Gigabyte MB, a SIS chipset and a P4-1,8GHz (dmesg to follow). The kernel is just GENERIC, with all debugging options commented out. sometimes (still, around once a day), when the machine starts swapping, it just freezes (it's possible sometimes to switch to a text virtual console and see the system messages), and it may unfreeze (or not). As the BIOS enables ACPI, it's even possible to shutdown gracefully from the power button. I have tried to start with all defensive options in /boot/loader.conf : hint.acpi.0.disabled=1 loader.acpi_disabled_by_user=1 hw.ata.ata_dma=0 hw.ata.atapi_dma=0 hw.ata.wc=0 hint.apic.0.disabled=1 and the freezes still happen. I will try to swap the disk (I did not see any ATA error message, like when the driver cannot read one disk sector - SMART is enabled on this disk, and the BIOS does not see any SMART error count) I have added a second (PCI) graphics card to the AGP board, and I'v setup the BIOS to use the PCI board as the console, the AGP board is only declared in /etc/X11/XF86Config. I wanted to see the vty0 messages while being under X11, but it seems as if the switch to X11 freezes the vty0, and the display is not refreshed (for example, if I leave a top in vty0, the display stays frozen with the last display). So [at long last] : is there a way to still have the display of vty0 refreshed on the PCI board, while X11 is displayed on the AGP board ? I suspect the keyboard is the blocking factor here (being exclusively attached to vty0 or X11) ? in the meantime, I'll try to keep an eye on xconsole, hoping all messages end up in the window.

strange 5.1 fxp behaviour [was Re: jumpstation configuration]
[I've seen your previous answer, but I still will describe my setup] [problems netbooting machines between fxp and em NICs] Hello, I am too seeing problems jumpstarting a machine (client) using a fxp NIC from a server (runnning 5.1-Rel) using an em NIC : the em NIC is wired down as 100baseTX full-duplex, but the 5.1-Release kernel seems unable to see it and tries to use a half-duplex setting (this surprisingly works when loading the install bits via ftp, with a rate of around 44kB/s, but fails completely when NFS is selected as install media). Everything works finer after switching virtual consoles on the client and ifconfig'ing the fxp1 as full-duplex, from the holographic shell. What is even more startling is that the same fxp1 is correctly set up as full duplex with the 4.8-RELEASE install kernel (from the same boot server, with the same setup for its NIC : I've installed two tftpboot directories so as to select which release is loaded via PXE). On monday , I'll try to wire the server em NIC as half-duplex to see wether the client fxp1 has a better throughput (afterwards, I'll try and look for differences in the 4.8 and 5.1 fxp drivers).

memory leak in libfetch ? (with patch)
hello, [this is using a 4.3-Release machine] I'm using libfetch for automated file transfers from a program (via ftp). The program is running for long periods of time, and seems to be leaking memory (at least it's SIZE in top(1) just grows and grows - the swap is also increasingly used). As there is no dynamically allocated memory in my program, one suspect could be libfetch(3). Indeed, there are 5 calls to malloc(3) in the source code of the lib : - in common.c, line 263, which should not cause a leak as the pointer is stored in buf, which is later saved, - in common.c, line 362, in a function which is not used in my app (the file name is known) - in fetch.c, line 377, in a function which is used only for http/https transfers, thus not in my app, - in http.c, line 517, in a function which is used only for http/https transfers, thus not in my app, - finally in ftp.c, line 434, in a suspicious manner : the io variable is located on the stack, thus visible only from this function, gets a pointer to a newly allocated ftpio struct and disappears after _ftp_setup() returns. The comparison between usr.bin/compress/zopen.c:zclose() and lib/libfetch/ftp.c:_ftp_close() shows a missing free(cookie) at the end of the function. the following patch seems to cure the memory leak : - --- ftp.c.ori Sat Apr 7 19:30:48 2001 +++ ftp.c Mon May 21 15:26:42 2001 @@ -422,7 +422,9 @@ io-err = 0; close(io-csd); io-csd = -1; -return io-err ? -1 : 0; +r = io-err ? -1 : 0; +free(io); +return (r); } static FILE * - TfH To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Re: Routing latency
Hello, the FreeBSD TCP/IP stack uses the "system tick timer" for some delay (maybe only for TCP). you may want to use a HZ=1000 option (see the LINT config file) in a recompiled kernel and see if things go better. (moreover, the dc(4) driver which is used for your NIC has some interesting performance improvements in the forthcoming 4.3-Release) TfH Mrten Wikstrm wrote: I've performed a routing test between a FreeBSD box and a Linux box. I measured the latency and the result was not what I had expected. Both systems had the peak at 100 us (microseconds), but whereas the Linux box had _no_ packet over 200 us, the FreeBSD box delayed some packets up to 2 ms! Looking at the time series, it seems that the packets are delayed at regular intervals, about every second. My guess is that some timer interrupt triggers every second and steals too much cpu. So my question is, how can I decrease this routing delay? Test info: I used two identical boxes, each equipped with a Pentium Pro 200Mhz and 64Mb mem. RedHat 7.0 with 2.4 kernel in one and FreeBSD 4.2-RELEASE in the other. I used two DEC 100Mbit ethernet cards (21140 I think). I measured the latency with a SmartBits instrument. Fastforwarding was disabled. Three UDP streams was sent from the SmartBits to one of the ethernet cards in the box, which routed the streams to the other interface, which in turn was connected back to the SmartBits. I had not made any changes to the standard kernel configuration. No other processes was running in the background, apart from those necessary to perform the test. The ARP table was set statically, so no ARP traffic would disturb. I would at least want to know what is causing the extra delays. /Mrten To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message -- Thierry Herbelot To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
scheduling frequency for threaded applications ?
Hello,
I'm developping a network benchmark application ("packet blaster").
The current version uses many processes, to send and receive packets,
and collate statistics.
when I look at top(1), I see most of the time taken is in the "system"
category. I assume this is due to the many context switches between the
collaborating processes.
If I want to get rid of this system overhead, one solution is to use
threads (all sharing the same address space, thus no more context
switching).
My question is : how otfen are the threads rescheduled ?
(all threads are mainly always blocked until an event arrives, either a
timeout with select() or a packet with recevmsg())
I've had a quick look a TFM, but I don't see anything applicable
(pthread_setschedparam(3) for example does not speak of scheduling
frequency)

You're incorrect. System means just about any time spent inside the
kernel (except interrupts), so basically syscalls count towards this
meaning that your application is driving the kernel pretty hard.
This is easy for a team of processes, but nearly impossible with
a thread based approach.
could you please elaborate ? (indeed, if you could also shed some light
on the first question : how frequently are threads rescheduled ?)
You don't want to use threads.

you can read a note by Alfred Perlstein on
http://people.freebsd.org/~alfred/pxe.html, the manpage for pxeboot,
the code in rc.diskless{1,2}, the configuration of the boot server with
dhcp and tftp/nfs (you may have to tweak /etc/fstab in order to mount a
root partition which was not used to load /kernel ?)
there is also somme documentation on Intel's web site

What to do if a box is just frozen
Hello,
I've got a little application at work which can "just freeze" a
4.2-Release : the purpose of the application is just a packet blaster
used for telecom equipement test (send as many UDP packets as ordered,
on as many interfaces as there are on a machine).
So, on my 4.2-R test box (no-thrills BX, P-III 700 intel box), I have
some tens (around 30 of them) of such processes sending their packets,
and after some time (I have to more precisely determine this "some
time"), the box simply locks.
I do not see any message on console.
I have connected a real keyboard (the box was connected to a KVM
switch), I have DDB enabled in the kernel, and the box is still freezing
(if it were at least panicing, this would be a good start) : I can't
jump with ctrl-alt-esc to DDB (even Ctrl-Alt-Del does not reboot the
machine).
The memory does not seem to be a problem, as there are around 50 free
megabytes (out of 128), if top is to be believed (the box does not run
anything else than the blaster). the kernel is compiled with 8192 Mbuf
clusters (runs of netstat -m give a use of around 400 out of the 8192
clusters)
the "freezing" happens when the blaster is run as root, and also happens
when run as a casual user.
the box has a reset button, but this obvioulsy erases any data in
memory.
Is there something I could do to debug this problem ? (is there any way
to force a crash dump, via a serial console perhaps ? what is really
depressing is the loss of control from the keyboard, not being able to
switch to DDB)
I will try to upgrade the boxes to a more recent -Stable, to see if the
problem still exists.
TIA for any idea

Are you sure it's not a hardware problem? Have you tried it with different
hardware?
positive : the box makes regularly the world or a kernel, and this is as
good a hardware test as can be (furthermore, the same programs, when run
in a smaller number, runs happyly)
I had a "just freeze" problem in FreeBSD 3.3, but I was able to duplicate
the behavior on other machines. They managed to whomp it for 3.4. Just
curious to see whether it has made it back for 4.2 ("It's BCK!!!").
I hope it isn't so : 4.x architecture is quite different when compared
to 3.x

Re: rpc.lockd and true NFS locks?
Hello,
I've recently seen in the NetBSD 1.5 release Notes that *they* claim to
have a fully functional rpc.lockd manager : "Server part of NFS locking
(implemented by rpc.lockd(8)) now works."
could someone have a look at what our cousins have done and perhaps
import it in -current ?

Re: Legacy ethernet cards in FreeBSD
"Koster, K.J." wrote: Dear All, Last night I cvsupped my trusty old Compaq Deskpro XL 6200 from 4.0-release to 4.2-beta. As part of that process, I seem to have lost support for the on-board NIC (lnc0: PCNet/PCI Ethernet Adapter, PC-net-32 VL-Bus). What is the newest version of FreeBSD that will propely support that card? If there are people who are cleaning up the support for older network cards in FreeBSD I'd like to help out by sending you my old NICs. It's not like they're any good to me without OS support. Please contact me off-list for any of the following cards: 3Com 3c503ISA should be ok with the ed driver, for correct values of irq and io range DEC EtherworksISA DEC DE205 ISA SMC EtherEZ ISA ditto RealTek "TP-Link" PCI As far as I've been able to determine, none of these work properly. In particular, the RealTek card gets detected and pretends to work, but loses the link after a bit (The link status LED goes out, and I need to reboot the box.) I'll be happy to try out patches for the lnc driver to fix the problem of the Deskpro, or to give remote access to it if you want to work on it.

1.2.3.197 fxp1
nat: 1.2.3.198
email:1.2.3.194
ns: 1.2.3.195
The problem I'm having is with my routing. Surprise. Here is
the routing table for the firewall:
default 1.2.3.193 fxp0
1.2.3.193 link#1 fxp0
1.2.3.192/29link#2 fxp1
1.2.3.196 lo0
1.2.3.197 lo0
The gateway_enable (net.inet.ip.forwarding) is also enabled on
the firewall.
with a *routing* firewall, like the one you are using, you must have two
different IP subnets, one for each physical interface (or else, the
kernel will not know which interface to use to send a packet).
In your case, you should use a "bridging" firewall, where ony one of the
ethernet interfaces has an IP address (you can then set up your firewall
in a "stealth" config, where it does not touch the TTL in the IP
packets)

Re: disappearing mount points after install
Hello [-mobile trimmed] Marwan Fayed wrote: Hello, I am a seasoned UNIX user but have been using freebsd for only about 6 months. I have posted this problem to freebsd-questions with no response so, figuring it must be a bug in the install program i'm going to try here. Oh, I would like to have traced the code to try to find the bug (if one exists) but being a senior year undergrad with a full course load and thesis, I have been left with little time... please forgive me. My problem is this. I am trying to install 3.3-R on an IBM Thinkpad 365XD (although I have received mail from a man in France who is having the same problem on a desktop). The installation runs completely smoothly but when I finish and reboot the machine reports no resident O.S. This may be due to a faulty BIOS : some BIOSes do not like at all not having a DOS partition at the beginning of the disk (I have some HP PCs with just 20 Megs of FAT at the start of the disk to keep them booting - from F2, which is FreeBSD) After trying many different things (including messing with the MBR, double and triple checking disk geometry, and using a Fixit disk to try to diagnose the problem), I booted from the install floppy to the main install menu. Rather than re-install all over again for the nth time I just entered the label editor. The partitions were still there but the mount points were lost. What appeared was this: none 40M // supposed to be root swap 84M // swap is obviously OK none 651M// supposed to be /usr The mount points for each partition are recorded in /etc/fstab : what you are seeing is completely normal, as sysinstall has not read the fstab file from the root partition of your disk. This is clearly not what I designated so I tried relabelling the mount points, writing the information using 'w' and exiting install only to have the BIOS report no O.S. yet again! Try and leave a small DOS partition at the beginning of your disk, as said above. The machine is a P100,40M ram,810HD, standard PCI (as far as I have been able to tell/test).
