isp(4) WWNs / ISP2532
Cheers,
we have a Qlogic ISP 2532 PCI FC-AL Adapter here, on 9.0-RC1, which
seems to work fine with isp(4).
But: We had some trouble finding the WWNs -- per man page, there should
be sysctl entries like dev.isp.N.{wwnn,wwpn}, but they ain't here. dmesg
didn't show them either.
Booting verbose does print them.
Is the man page outdated, or a strange behaviour because this chip
isn't explicitly supported?
Thanks,
- D.

There's an ioctl you can use to do the same thing and some tools in
http://people.freebsd.org/~mjacob/isp_tools.tgz that can solve what you
need.

How are you setting CC and/or CFLAGS, precisely? Depending on how you
do it, the settings might not be propagated correctly to the build32
stage. Also, if you force CFLAGS to have -march=athlon64-sse3, I'm not
sure if the build32 stage can even work correctly. Just specify
CPUTYPE, that should be enough.
In any case, you can try out the attached patch, which should take care
of passing CC to the build32 stage correctly.
I would really like to have this in head, and even stable/9. It makes
it possible to just set CC in make.conf, without .ifdef trickery. Works
nicely for clang, too. :)

Shipped kernels have all assertions turned off. Yes, I'm aware of that, but many people compile their production kernels with INVARIANTS/INVARIANT_SUPPORT to fail early instead of eg. corrupting data. I'd be fine in moving this under DIAGNOSTIC or changing it into a printf, so it will be visible. No, the kernel is corrupting things in other places when this is true, so if you are running with INVARIANTS, we want to know about it. Specifically, in several places in TCP we assume that rcv_adv= rcv_nxt, and depend on being able to do 'rcv_adv - rcv_nxt'. In this case, it looks like the difference is consistently less than one frame. I suspect the other end of the connection is sending just beyond the end of the advertised window (it probably assumes it is better to send a full frame if it has that much pending data even though part of it is beyond the window edge vs sending a truncated packet that just fills the window) and that that frame is accepted ok in the header prediction case and it's ACK is delayed, but the next packet to arrive then trips over this assumption. Since 'win' is guaranteed to be non-negative and we explicitly cast 'rcv_adv - rcv_nxt' to (int) in the following line that the assert is checking for: tp-rcv_wnd = imax(win, (int)(tp-rcv_adv - tp-rcv_nxt)); I think we already handle this case ok and perhaps the assertion can just be removed? Not sure if others feel that it warrants a comment to note that this is the case being handled. I added debug to the places where rcv_adv and rcv_nxt are modified.

usbus seen as network devices
I've noticed that with 9.0-RC1, usbus[0-9] are seen as network interfaces. I figured this is need for usbdump to work. (This isuue has been raised before [1], but no helpful replies were given). I find this behavior rather annoying: 1) usbus0 is the default interface (in 8.2, my primary network interface was default) # tcpdump tcpdump: WARNING: usbus0: That device doesn't support promiscuous mode (BIOCPROMISC: Operation not supported) tcpdump: WARNING: usbus0: no IPv4 address assigned tcpdump: packet printing is not supported for link type USB: use -w 2) Various tools (netstat, tcpdump, wireshark, my network monotoring dockapp) now list 8 additional interfaces: # netstat -i NameMtu Network Address Ipkts Ierrs IdropOpkts Oerrs Coll usbus 0 Link#1 0 0 00 0 0 usbus 0 Link#2 0 0 00 0 0 ... 3) I can do rather silly things, that at best will do nothing: # ifconfig usbus0 10.0.0.1 # usbdump -i lo0 Some applications seem to check the link type, so that unsupported interfaces are not shown. But the behavior isn't even consistent in the base system: - ifconfig -a doesn't show usbus interfaces, but lets you happily configure them - tcpdump -D shows the interfaces, but bails out if you actually start capturing - netstat shows them - systat -ifstat only lists real interfaces Do all these applications need to be patched, or can this be fixed in a single place (in the kernel)? Is there a kernel option/sysctl/etc. to disable this behavior? I'm most likely not going to need usbdump in the foreseeable future.

FreeBSD 9.0 amd64 RC1 and KDE4

The KDE4 in FreeBSD 9.0 RC1 i386 is working satisfactorily , but for memory requirements , it is not an alternative . There are important usability differences between both architectures with respect to KDE4 execution . One alternative is mentioned as PC-BSD , but installation of PC-BSD is NOT possible : In PC-BSD 8.2 amd64 Release and following snapshot(s) , within 18 ( eighteen ) hours , only a small percent ( less than % 10 ) could be installed . Now , in PC-BSD 9.0 RC1 amd64 , I am still waiting : In 4 ( four ) hours it could come to Installing Meta Package : base-system . Such an installation structure is really unusable . I will discontinue it because it seems that complete install will require many days with that speed . I am continuously installing many other distributions which mostly they are consuming time around thirty minutes ( except upgrade during installation , if it is selected ) . Thirty minutes may be considered an acceptable duration for installation , let's say , time less than one hour as endurable . It should not be forgotten that , the task is copy of approximately 4 Giga Bytes to hard disk from a DVD-Rom with an additional decompressing of files .

In a message previously I mentioned the KDE4 problem for 8.2 amd64 Release , but that message even did not receive a single reply . Always I may help with pleasure , but I do not know how . I think the problem is not related to hardware because i386 KDE4 is working very well . On the same computer , there are four hard disks , and each disk has a different operating system , mostly 64 bit ones . All of them using KDE4 and working very well . If you consider useful , my ideas are following : During start-up of KDE4 , screen is painted with its wall paper only . Since X is already running , it is possible to open a window and display messages on it with possible saving to a text file . This file may be transmitted to experts for possible studies . At present , monitors are cheap . I want to install multiple monitors on the same computer to watch serial console output on a regular ( VGA ) monitor ( because in market , there is NO any serial console on sale in computer shops ( I am in Turkey )) . Really , I do not know how to implement a regular ( VGA ) computer instead of a serial console . A very good application in FreeBSD may be to allow such a multiple monitor definition during install and use them for virtual terminals simultaneously . Using a second computer for serial console is not very practical due to software and hardware problems . If you know my actual problem , you may understand me better . I am writing a multimedia information management system as continuation of my PhD thesis feasibility demonstration program . Due to health problems it is progressing very slowly . My primary aim is to base it on a free , permissive , open source operating system . My program , with a freely usable version , will be closed source ( for sale , if I can do ) . I need a permissive ( BSD like licensed ) operating system , because a data base without operating system support can not be secure in itself . Unfortunately , I am using Pascal only , Fortran for scientific programming and very rarely C , ( with a knowledge of other many programming languages ) . I want to start on working internal structure of an operating system . Linux is NOT usable due to GPL . Minix ( does not have a capable Pascal ) , Haiku , are not sufficiently mature . NetBSD , OpenBSD , DragonFlyBSD are not better than FreeBSD . OpenSolaris died , OpenIndiana is using copyright dependent parts . The most viable selection is FreeBSD for 64 bits ... In such an environment , usability of multiple terminals ( monitors ) simultaneously as distinct display areas with output direction possibility via parameter files would be very useful . Assume values are written into distinct files , where files are monitors . Not only for my own benefits , also for contribution to humanity ( My main hobby was to write mathematical analysis programs to support researches , with very hard work : Conclusion : My wife had divorced me with a complaint that I am studying very much , occupying home with computers , etc. ) , I always wish to make contributions to FreeBSD because of its very good license ( even commercial companies may use it freely which is a very good decision for me ) and its high quality . To test the KDE4 in FreeBSD 9.0 amd64 RC1 , you can do the following : Install X . Install KDE4 . Login to console . Without an .xinitrc file , and unmodified /etc/ttys file , execute startx . ( Do not start KDE4 directly . ) In right xterm window of X , execute /usr/local/kde4/bin/startkde ( /usr/local/kde4/bin is not in path definition ) . In that terminal , you will see a lot of messages . After display of messages , a form will appear to display KDE4 . Then , I do not know , but , even this will supply much information about what is going problematic .
