In the past, CMU's PDL (and possibly others) have provided FreeBSD cross-reference web pages, but I was unable to find one once that site went down. As such, I've experimentally set up the LXR software with access to several branches of the FreeBSD source code, as well as 2.4 and 2.6 Linux kernels at: http://fxr.watson.org/ Thank you very very much! ;-) Atlast, someone got to it. I have been wanting to setup LXR for DragonFly for quite some time now, but did not have enough time on my hands to mess with it. Does it require any sort of patching for it to work on FreeBSD ?

This brings up something I've been wondering about, which you might want
to investigate:
From tcp_output:
if (error == ENOBUFS) {
if (!callout_active(tp-tt_rexmt)
!callout_active(tp-tt_persist))
callout_reset(tp-tt_rexmt, tp-t_rxtcur,
tcp_timer_rexmt, tp);
tcp_quench(tp-t_inpcb, 0);
return (0);
}
That tcp_quench knocks the window size back to one packet, if I'm not
mistaken. You might want to put a counter there and see if that's
happening frequently to you; if so, it might explain some loss of
performance.
Maybe something like this:

pmap_wired_count() macro?
Hi Gang. Can someone enlighten me as to where I can find the pmap_wired_count() macro? I have tried a quick grep through sys but I am not able to find where it is. I ask this because I was browsing through our mlock() implementation and the 'ifndef pmap_wired_count' and was wondering what it did. I do have an idea what this macro would do, but I just failed to find it in our src tree.

I don't know how find-sb compares to the program you're talking about, but they sound kind of similar. Scan_ffs can print the lost disklabel for use with disklabel(8). Find-sb, that version from cvs, seems only to print info about the superblocks of each file system and you have to rebuild the lost disklabel for your self. I was on the search for a simple tool for everybody, and found scan_ffs several months ago in the OpenBSD distribution (so it seems find-sb was like reinventing the wheel) and Robert Watson suggested in a posting december last year to adopt scan_ffs for UFS2. IMHO we should reuse a already written program with existing man pages, so we have the same sounding tools for the same tasks. I don't know what find-sb could do with your patches applied. If it's superior to scan_ffs, we can forget scan_ffs. FWIW, I did make scan_ffs work with UFS2 at one point in time, but I lost my stuff in a disk crash. It's a pretty good utility with good documentation. The only thing you need to worry about in the scan_ffs code is the opendisk() routine, or something like that, but it shouldn't be hard. -- Hiten Pandya ([EMAIL PROTECTED], [EMAIL PROTECTED]) http://www.unixdaemons.com/~hiten/ To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Re: FEC doesn't build on 5.0
Hello
Heither of the original (http://people.freebsd.org/~wpaul/FEC/) not
the in tree FEC implementations build.
Hi there. The reason it doesn't build is because, the ng_fec was
somehow left out when Sam Leffler was making changes to the
ether_if{de,at}tach() and bpf interfaces. Anyway, a complete fix, which
should be committed is attached with this mail.
Also, I believe you have used the implementation from wpaul's website.
Could you try using the `in-tree' version of the FEC Netgraph driver,
because many of the ifnet_addrs* related problems have been resolved in
it by julian@.

System-wide totals via sysctl (struct vmtotal)
Hello Gang!
Currently, people, the vm.vmmeter sysctl is bogus and misleading. It
refers to struct vmtotal, which gives us the system wide totals, and
does not relate/refer to struct vmmeter in _any_ way.
It is silently skipped by sysctl -a listing, because there is no handler
for it:
# sysctl vm.vmmeter # nothing returned...
# sysctl -ao vm.vmmeter
vm.vmmeter: Format:S,vmtotal Length:48 Dump:
It has been this from the days of 3.0-CURRENT, and earlier, I think. PR
kern/5689 addressed this problem. Johan Karlsson assigned this PR to
phk@ in 2000 (submitted: 1998), but no action was taken by anyone anyway,
and eventually, patch was left to rot.
Well, I have updated the patch for 3.0-CURRENT, for our latest -current,
and also made one more change vmmeter-vmtotal, as requested in the PR.
The patches are attached with this mail. I would be very grateful is
someone can commit (and review) them for me.
Cheers.

It's been around on the list for a while, but if it's working for the people involved, they are not saying anything. Last I heard, the person who had the problem had tried the Intel Gigabit card, but not the Tigon III, but was looking for a Gigabit card recommendation. I suppose I could make the same patch for the Intel card. The problem is that DEVICE_POLLING is an all-or-nothing thing, you can't control it on a card-by-card basis, even with a sysctl, because it fills out an entry point that's statically, rather than procedurally initialized. Basically, that means that the worst case, you could not turn it on for cards that are known to work, if the patch fails to work for the Tigon III. If someone with a Tigon III card could try the patch with the DEVICE_POLLING option enabled, and device polling turned on, and let us know that the card keeps functioning, rather than them getting a panic, then that would be enough, I think, to say commit it. I think the Device Polling sysctls will need tuning, if I am thinking straightly.

It has a pretty good interrupt reducer in it by itself. Just tune the 2 rx and the 2 tx parameters and you get a constant interrupt rate with good latency for any packet rate. This is hardware interrupt coelescing. It is a totally seperate thing. The point of DEVICE_POLLING is to avoid the receiver livelock case, when you are under extreme load. What this probably means is that you haven't put enough load on the hardware to see the livelock case. Actually I have pushed it to the livelock case. I'm shocked at how easy this is to do with BSD (I'm used to system like vxworks with much lower over head interrupt processing). I found that for a 2x XEON @ 2GHz that I can achieve this @ ~100Mbps of minimal size UDP fragments. Tuning the driver dramatically improved the situation. Reducing the size of its receive ring to the proper amount also helps since it will then run out of buffers and drop packets. This isn't extreme load, it isn't really particularly heavy load, its only like ~200Kpps. I suspect the defragmenting is the issue, so I tried it again with ARP's. This helped a lot. I'm still not clear on how the receiver polling helps me, it also makes a constant rate consumption of packets. If I set the bds to the max, then I will only be interrupted @ constant rate by the device. Thanks to Luigi for writing a nice manual page on Device Polling operation. It explains most of the things clearly. There is also something about tuning the HZ kernel configuration option. FYI, the manual page is polling(4).

Fixing issues with the MSDOSFS code. [w/ PATCH(es)]
Hello all.
OK. I am going to get straight to the point. I was going through the
PR database yesterday, and I saw that there are three PRs submitted on
one same MSDOSFS issue.
As we know, that there is no MSDOSFS maintainer; I have taken the
courage to gather the patches, which, have know to work, and are still
applicable to date. Below is my research: :-)
I am submitting this, in the hopes, that a committer will pick them up,

The problem as submitted by the author (kern/24393) is:
There are sometimes a FAT filesystems not handled correctly by msdosfs
driver, but handled by mtools and other OSes. The problem is that
msdosfs assume . entry in directory have cluster number set to real
directory cluster number. But sometimes cluster number for . entry is
set to 0, and msdosfs behaves wrong with such filesystems.

SysV IPC related question
Hi all.
I was wondering why we have a struct mymsg in sys/msg.h, when many
utilities defined their own version of it. I am curious about this
because our stock version of struct mymsg:
struct mymsg {
long mtype; /* message type */
char mtext[1];/* message body */
};
Why do we have a value of [1] in the mtext array? Are we meant to
define a struct mymsg at all!?
Thanks.

This is the message contents. It is an overlay structure. The
[1] is the same thing that, in the current ANSI C standard, you
would define in terms of [0].
The point is that you have a structure that sonsists of a long
followed by an indeterminate number of bytes. You cast the
combination to a pointer to a structure of this type, and you
can reference the long as mymsgp-mtype, and the contents as
mymsgp-mtype.
Please leave it alone. 8-).
OK. One more question; so, is there any particular reason why our cousin
NetBSD doesnt use this overlay structure? Also, the NetBSD SysV Msg
regression tool defines its own struct mymsg; and doesnt have one standard
in the sys/msg.h header file.
Also, if possible, could you outline some situations where this would be
used? Help will be very appreicated.
Thanks.

This patch is located at: http://storm.uk.FreeBSD.org/~hiten/diffs/vfs_syscalls.diff.1 The second issue, is what I am not very sure about, but I had a little discussion about this with rwatson. The vfs_subr.c module contains a large #if 0'ed section, which basically contains some sysctls. I think it has been forgotten for removal, so I am submitting a delta which can be used to remove that #if 0'ed section.

Have you tried to use any of the sysctl(3) functions? Try doing the

The int= number is the fault that was triggered. Then, use a program to convert the hex dump at cs:eip to binary Which tool can be used for this task? Any available in the ports? and run that through ndisasm or ndisasm -U depending on if the code segment in cs is USE32 or not) to see what instruction it died on. You then look up that instruction in teh reference manual and see how the given fault can be triggered. Some faults are rather obvious just from the fault number and don't require you to look up the instruction. Sometimes it's not the actual instruction that's the problem, but instead you managed to hose the stack or some such in which case you just ahve to look at the register and stack dumps to try and figure out what went wrong.

about sysinstall(8) package managment
hi all, I was wondering that, the sysinstall(8) utility doesn't have package managment facilities designed for people to view even if they don't have some kind of connection to the media. Example: When you select the 'packages' option, it will ask you about your media type. If someone doesn't have any of the media, than, they wouldn't be able to know what packages are installed on their system. (Only by doing pkg_info, but not from sysinstall.. :) What I am suggesting is, that we can make a section in the sysinstall configure menu, where we can show all the currently installed packages, and we can link up the current pkg routines such as adding, removing, so that people can easily see what packages are installed, and they can also remove them from that menu.. let me know about your views on this.. thanks, regards, - Hiten - [EMAIL PROTECTED] = SSH Fingerprint: 1024 45:a5:9c:f2:fb:07:da:70:18:02:0b:f3:63:f1:7a:a6 [EMAIL PROTECTED] __ Do You Yahoo!?

Re: Instead of JFS, why not a whole new FS?
--- Dave Reyenga [EMAIL PROTECTED] wrote: How about writing a new filesystem based on UFS? This would save all of the hassle that JFS would bring: licensing, porting time, etc. Of course, it would likely bust any compatibility desired. hi, first of all, a project called UFS2 has been started by Kirk McKusick on improving the existing UFS file system and improving 'softupdates' and other stuff in this file system. What I'm thinking is a filesystem that takes the current UFS and improves upon it. It could support larger partitions, more partitions in a slice, and perhaps a Journal partition (like the current swap partition) among other new features. I dont know that this could be possible of having a 'Journal' partition, though I may be wrong. What do others have to say about this? Are there any major flaws in my idea? It just seems to me that this would cut a lot of hassle. One flaw in your idea is, that it would literally take longer to make this kind of file system on our current UFS source base. The reason is due to the code maturity level that UFS has reached of around 20 years. I think porting JFS will take less time than upgrading the current UFS, which as a matter of fact has already been started by Kirk McKusick himself. Regarding 'hassle', for me; nothing is a hassle as long as it can be acheived. If you are really interested in upgrading the current UFS, it would be good if you got in touch with Kirk McKusick himself. regards, =Hiten =[EMAIL PROTECTED] = =Hiten =[EMAIL PROTECTED] __ Do You Yahoo!?

Do you see the problem yet? Libstand (and hence the loader) could be extended to allow reading files from jfs without using any GPL'ed code. For example our loader can load modules from the FAT even though we do not have any M$ code. :) Alternatively, /boot could be placed on separate filesystem, which could be ufs or anything else supported by the loader. Patches appreciated. Note that if you do a read-only JFS, you are more than half way there to a n0n-GPL'ed implementation, so you might as well finish it off, instead of porting the IBM code. -- Terry = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k __ Do You Yahoo!?

Re: cable modem connection problem
what kind of mucking could cause such kind of behaviour?. this kind of problem did occur to me several times with NTL (http://ntl.com/) in UK... there were installing a Universal Shared Bandwith Router in their CO (Central Office), after they installed this piece of sh*t, the bandwith was throttled from 5.00pm evening to 5.00am morning, which was to slow down users from downloading large files i.e. Music Sharing and such but after 5.00am, it was all fine and back to 85.0KBps when before 5.00am and after 5.00pm was around 12.0KBps which is sad but was true for a while till users complained about it... (like me)... so that is a possibility, or it could be that the signal you are receiving (cable modem signal) is very weak thats a possibility too... =Hiten =mailto:[EMAIL PROTECTED] = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k __ Do You Yahoo!?

[SUGGESTION] - JFS for FreeBSD
hi all, this is a wild idea...suggestion... i wanted to ask if there were any _plans_ to port JFS (Journaled File System) to FreeBSD... as for JFS, it is developed by IBM for Linux and is licensed under GPL, so we could put this into src/gnu/ It is used on IBM MainFrames and Enterprise servers for high performance and maximum throughput... = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k __ Do You Yahoo!?

Re: [SUGGESTION] - JFS for FreeBSD
hi, the license issues dont really affect us... after all we have an src/gnu directory... thats what it is for... dumping GPL'ed stuff and talking about GPL, we can even publish the code as the GPL license states... after all we are an open Source Project, but if we were commercial... it would have affected us.. but thats not the case... the only other thing is, i am itermediatory C programmer and i have never ported a filesystem before. but.. that doesn't affect me a lot.. its experience which i will gain... After all the whole of the FreeBSD Team is on my back, so there is nothing to worry about... have already turned the Source code tree for JFS into DoxyGen Generated Pages... i have started to look into it... I am sure it is possible to port it to FreeBSD... though... it may be a bit trickier (not hard)... never say never :-) =Hiten =[EMAIL PROTECTED] --- Alfred Perlstein [EMAIL PROTECTED] wrote: * Matthew Emmerton [EMAIL PROTECTED] [011210 16:40] wrote: * Hiten Pandya [EMAIL PROTECTED] [011210 16:02] wrote: hi all, this is a wild idea...suggestion... i wanted to ask if there were any _plans_ to port JFS (Journaled File System) to FreeBSD... as for JFS, it is developed by IBM for Linux and is licensed under GPL, so we could put this into src/gnu/ It is used on IBM MainFrames and Enterprise servers for high performance and maximum throughput... I'm glad you took the time to read the marketting literature. The problem is that porting it is going to be a bit more complicated than just dumping it into src/gnu. Feel free to take a shot at porting it though, let us know when you're done. I'm gainfully employed by IBM (although not for FreeBSD pursuits), and have had this on my TODO list for a while. The licence issue is a real sticky point, especially since the GPL and BSD licences are like oil and water. Because of the GPL licence, JFS support can never become part of the GENERIC kernel, and any related support tools will have to exist as separate binaries (newfs.jfs, fsck.jfs), as is currently done with the EXT2FS filesystem. This is pretty much how they all work, on netbsd the LFS filesystem has its own suite of seperate utilities as well. Don't be discouraged, get hacking! :) = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k __ Do You Yahoo!?

Re: Tangent for discussion: FreeBSD performs worse that Linux
hi, does anyone need any special skills to manage the kind of branch you are talking about... example.. RELENG_4_4_BUGFIX what kind of skills and experience in FreeBSD would be needed for this kind of branch -Hiten I could maintain a not-FreeBSD-sanctioned site for patches of -CURRENT and -STABLE code applyable to previous releases, but that would only muddy the FreeBSD maintenance and distribution waters that I think work well for what they're intended to address, as well as open myself up to all sorts of support and maintenance headaches. i wouldn't mind helping :-) = -Hiten, Thank You, Yours Sincerely, Hiten Pandya, [EMAIL PROTECTED] http://www.geocities.com/hitmaster2k __ Do You Yahoo!?

RE: (no subject)
hi, i am butting in the argument half way but... although i am new to FreeBSD... what i am saying is... even if intel's driver is better... i dont care about that because... after all, thats their device... so.. of course they will make the device driver better ecause they were the ones who made the device in the first place... but in time.. the ng driver will become good as well... after all... we are quite far away from releasing 5.0... regards..
