portupgrade O(n^m)?
I have 734 ports installed on my laptop right now. I'm pretty sure, at times, I've had over 1000 ports on my laptop. On machine with moderate numbers of ports (most servers seem to have 50 to 200 ports), portupgrade takes a moderate amount of time to start work. On machines like my laptop, portupgrade seems to take much more time to run. I assume it's solving the dependency graph before it decides what to upgrade first, but is this truly a O(n^2) problem? It seems like the implemented algorithm is O(n^2).

4th loading a module.
I'm no forth expert --- but I have a basic understanding on how it goes together. I can also follow expamples. What I want to do is load a module (if_iwiNG or snd_ich) based on a menu choice at the beastie menu. I have successfully added the manu item and a variable --- following the example. I tried adding: dup bootwifikey @ = if s YES s if_iwiNG_load setenv 0 boot then to the end, but it doesn't work. load_modules has already been called. I tried (out of the blue) s if_iwiNG load_module ... but that's not the correct recipe (at least... 4th crashes if I load that code). I don't see any other examples of loading a single module by command. I'd appreciate it if someone could provide the requisite magic incantation.

dump reads more than restore writes?
I've got a command line like the following: dump -0af - /dev/ad1s1g | restore -rf - ... and I'm watching gstat. ad1s1g is not mounted. The disk on which the restore is running is also quiet (nobody using the disk). And gstat says that ad1 is consistently reading 31 to 37 megabytes per second and ad2 (the restore disk) is consistently writing 10 to 13 megabytes per second. This is over hours --- the figures never catch up. So... is gstat wrong? Is dump reading substantially more than restore is writing?

Dan == Dan Nelson [EMAIL PROTECTED] writes: Dan If you have a lot of small files, dump may be rereading directory Dan information. Dump has a cache option that can help, but make Dan sure you also dump a snapshot (i.e. always use -L when using -C). Several people have suggested this, but actually it has the same behaviour when using -C (I often use -C 32). This filesystem is not mounted, so -L is not required, but I do use -L when required. But the filesystem is 95% full (aren't they all) and the vast majority of the files on it are media files --- ie: movies, mp3's, ISOs, etc. Very few files under a meg. Probably not too many files over 100 meg as most of the files on the disk are in rar format. ... now Azurus (used to obtain most of the files) writes holey files. One chunk at a time (512k-ish to 4meg-ish). Those could end up being not-very-contiguous, but I'd expect them to consist (by majority) of full filesystem blocks. The amazing part (to me) is how consistent it is. If this is not a reporting error of gstat, it makes dump look _very_ wasteful. If the numbers are being reported correctly, it means that dump is reading 600 gig to copy a 200 gig disk. !?!

Detecting buffer space with UDP.
I'm using kqueue() with a EVFILT_WRITE to send udp packets over a gigabit interface (the job here is to stress test DNS servers).

dhclient-script impotence.
According to the documentation, dhclient calls dhclient-script for every action. It does not. It appears that dhclient only calls dhclient-script (now) to set the media. At the very least, the documentation is wrong. But the functionality that was dhclient-script was useful in many ways... not the least of which is situations where adding a default route is not the right activity. I have also noticed that dhclient (the new one) doesn't appear to correctly notice atheros wireless state changes. It doesn't appear to try to reacquire ip addresses when you roam into a new open access point network.

There are systemic things like the fact they want to ignore lo0 destined routes (although I know how to patch that), but there are less obvious things that I havn't figured out.

I've got an OnTrak ADU208. It's a USB device that has 8 relays and 8 ttl inputs. The documentation says it uses two interupt endpoints ... one input and one output. It seems to expect small text commands. Now... firstly, uhid is probing it as uhid0: uhid0: www.ontrak.net ADU208 USB Relay I/O Interface, rev 1.10/0.00, addr 4, iclass 3/0 ... I don't know if this is hindering me. The usbhid* commands aren't particularly helpful. The port udesc_dump seems only to work on ugen devices ... and ugen doesn't pop up for this device.

Here is an odd situation. If I start quagga ospfd after creating gre, tun, or gif devices, ospfd recognises them as point-to-point interfaces and everything works. However, if I start quagga and then create interfaces afterwards, the interfaces are not recognised as point-to-point interfaces and OSPF packets only travel in one direction (into the box). I'm not sure if the problem lies solely with quagga or FreeBSD or a little of both. For one, does the GRE device not have the POINTOPOINT flag set immediately?

Odd geom behaviour.
I have a set of 12 disks. 2x9G and 10x4.5G. I have a setup whereby I run a gmirror on each pair of disks and then a gconcat on the mirrors. Attached is a copy of the gmirror and gconcat lists. Now... I shutdown -r this machine (which happens to be an alpha) and it shuts down happily. However, _every_ time it reboots, it wishes to rebuild the mirrors: GEOM_MIRROR: Device m1 created (id=4055141955). GEOM_MIRROR: Device m1: provider da1 detected. GEOM_MIRROR: Device m1: provider da2 detected. GEOM_MIRROR: Device m1: provider da2 activated. GEOM_MIRROR: Device m1: provider mirror/m1 launched. GEOM_MIRROR: Device m1: rebuilding provider da1. (x5 more for the other mirrors). Now this isn't particularly bad, I suppose, except that the machine is occupied for some number of minutes after boot with this activity. No fsck ... the filesystem is happy. The machine is available for testing should someone want to look at it. In fact, the machine is part of my retrocluster of hardware running FreeBSD and NetBSD (if someone needs hardware with serial consoles to debug, this is the purpose of the retrocluster).

Hardware Serial Numbers under FreeBSD

Certainly the canonical way to get a serial number is the ethernet hardware address. On some cards, you can change it, but many copy protection systems work on MAC addresses. Now, most cards reset to their default MAC address on boot, so if you run early enough, you should be fairly immune from tomjiggery. ifconfig prints it out, among other commands. The reason this is doubly good now is that most motherboards have ethernet built in... so you could consider it (for the purposes of inventory) a motherboard serial number.

GCC include files conundrum.

I started investigating this and found that this was all due to some differences in C++ over the years. The error on bento comes down to bento not having strstream.h. I have that file as: /usr/include/c++/3.3/backward/strstream.h /usr/include/g++/backward/strstream.h on my -CURRENT (as of a week or two ago) laptop. bento does appear to have /usr/include/c++/3.3/backward/iostream.h ... but not strstream.h. Why? I realize that my source upgrading may have left around a few old files, but I don't see a replacement strstream.h. The C++ FAQ referred to by iostream (not iostream.h) seems to imply that you should use iostream and sstream (no .h)... but including those files imposes a very different standard that this port is not ready to accept. It appears that (among other things that I havn't found yet) all 'istream' must be written 'std::istream' ... etc. So what's the solution?

Large arrays that we run tend to have multiple system images (for diskless or semi-diskless operation) and many more thousands of users ... all with their usual complement of small files. It strikes me that driving the block size up (as far as 1M) and having a 256 (or so) fragments might become appropriate. We probably also need to address disks with larger block sizes soon, but that's another issue alltogether.

wi0 still not being a good hostap.
Well... I was wrong. Interrups under 5.1-CURRENT still cause the wi0 running in hostap mode to shed it's clients. I'm not familiar with what 802.11b does to authenticate et. al., so I'm posting this ifconfig debug output from both the server and the client in hopes someone else knows what's happening. This particular system has two clients. It's worth noting that when I had a normal access point, I had no problems. This appears to be a problem with the wi0 in hostap mode. The server says: wi0: sending assoc_resp to 00:40:05:ae:b1:bf on channel 11 wi0: station newly 00:40:05:ae:b1:bf associated wi0: received disassoc from 00:40:05:ae:b1:bf rssi 42 wi0: station 00:40:05:ae:b1:bf disassociated by peer (reason 8) wi0: received auth from 00:40:05:ae:b1:bf rssi 41 wi0: sending auth to 00:40:05:ae:b1:bf on channel 11 wi0: station already 00:40:05:ae:b1:bf authenticated wi0: received assoc_req from 00:40:05:ae:b1:bf rssi 39 wi0: received auth from 00:40:05:ae:b1:bf rssi 42 wi0: sending auth to 00:40:05:ae:b1:bf on channel 11 wi0: station already 00:40:05:ae:b1:bf authenticated wi0: received assoc_req from 00:40:05:ae:b1:bf rssi 42 wi0: sending assoc_resp to 00:40:05:ae:b1:bf on channel 11 wi0: station newly 00:40:05:ae:b1:bf associated wi0: station 05:ae:05:ae:b1:bf deauthenticate (reason 6) wi0: sending deauth to 05:ae:05:ae:b1:bf on channel 11 wi0: received auth from 00:04:e2:1e:11:d7 rssi 35 wi0: sending auth to 00:04:e2:1e:11:d7 on channel 11 wi0: station already 00:04:e2:1e:11:d7 authenticated wi0: received assoc_req from 00:04:e2:1e:11:d7 rssi 33 wi0: sending assoc_resp to 00:04:e2:1e:11:d7 on channel 11 wi0: station already 00:04:e2:1e:11:d7 associated wi0: received auth from 00:40:05:ae:b1:bf rssi 40 wi0: sending auth to 00:40:05:ae:b1:bf on channel 11 wi0: station already 00:40:05:ae:b1:bf authenticated wi0: received deauth from 00:40:05:ae:b1:bf rssi 40 wi0: station 00:40:05:ae:b1:bf deauthenticated by peer (reason 3) wi0: received assoc_req from 00:40:05:ae:b1:bf rssi 38 wi0: station 00:40:05:ae:b1:bf deauthenticate (reason 9) wi0: sending deauth to 00:40:05:ae:b1:bf on channel 11 wi0: received auth from 00:40:05:ae:b1:bf rssi 37 wi0: sending auth to 00:40:05:ae:b1:bf on channel 11 wi0: station newly 00:40:05:ae:b1:bf authenticated wi0: received assoc_req from 00:40:05:ae:b1:bf rssi 40 wi0: sending assoc_resp to 00:40:05:ae:b1:bf on channel 11 wi0: station newly 00:40:05:ae:b1:bf associated wi0: station 00:40:05:ae:00:05 deauthenticate (reason 6) wi0: sending deauth to 00:40:05:ae:00:05 on channel 11 wi0: receive packet with wrong version: d5 wi0: receive packet with wrong version: d5 The client says (not nearly so long a sample): wi0: D Link DWL-650 11Mbps WLAN Card at port 0x100-0x13f irq 11 function 0 config 1 on pccard0 wi0: 802.11 address: 00:40:05:ae:b1:bf wi0: using RF:PRISM2.5 MAC:ISL3873 wi0: Intersil Firmware: Primary (1.0.7), Station (1.3.5) wi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 disassociate (reason 8) wi0: sending disassoc to 00:05:5d:ee:e6:e7 on channel 11 wi0: station 00:05:5d:ee:e6:e7 deauthenticate (reason 3) wi0: sending deauth to 00:05:5d:ee:e6:e7 on channel 11 Dave. -- |David Gilbert, Independent Contractor. | Two things can only be | |Mail: [EMAIL PROTECTED]| equal if and only if they | |http://daveg.ca | are precisely opposite. | =GLO ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Upgrade to 5.1 fixes wi0 accesspoint mode fubar.
For various reasons, I upgraded my firewall from 4.8-STABLE to 5.1-CURRENT. Recently, I complained that the wireless clients of the wi0 PCI card running in hostap mode would loose sync. It was repeatable that they clients would loose sync when the server was serving more interrupts. One of the most obvious expamples was playing xmms on the server would cause disassociations of the clients. Upgrading the server to 5.1-CURRENT seems to have fixed the problem. Just a report. 4.8-STABLE is still broken... but it's less convenient for me to attempt any tests now.

Simply impossible to format disk under current.
I ran into an interesting problem last night ... that was very frustrating. I was recycling SCSI drives from some NetBSD machines (that were client boxes) to add to a RAID server running FreeBSD-5.0-RELEASE. It's simply impossible to format NetBSD drives under current. Let me expand on that. /dev/da2 exists, but you can't say 'fdisk -I da2' ... fdisk says that /dev/da2 doesn't exist. /dev/da2 (and /dev/da2c) isn't writable, so I can't blank the first few sectors. I even tried this in single user mode. The problem appears to be that the FreeBSD-5.0 system sees the NetBSD label ... so things like da2s1 don't exist. da2a, da2b, da2c and da2g do. These are the NetBSD partitions. Writing to them is verboten. I was hoping that da2c would allow me to blank the boot sector, but it doesn't allow me to write. ... under FreeBSD-5.0, fdisk won't write to the disk and disklabel won't change the NetBSD label, either. I had to boot with my FreeBSD-4.7 recovery CD ... which would fdisk and disklabel the disk (note that fdisking wasn't enough ... FreeBSD still accepted the NetBSD label over the fdisk data) just fine. ... although I then ran into the issue that disklabel -e had /mnt2/stand/vi hardcoded into it ... which is wrong.

Re: [hackers] Re: Netgraph could be a router also.
Terry == Terry Lambert [EMAIL PROTECTED] writes: Terry These stats are moderately meaningless.

Terry And is that a unidirectional or bidirectional rate? UDP? Terry I guess I could guess with 200kpps: Terry 100mbit/s / 200kp/s = 500 bytes per packet Terry ...and that an absolute top end. Somehow, I think the packets Terry are smaller. Bidirectionally, not FDX, we're talking 250 bytes Terry per packet maximum theoretical throughput. Well... I have all those stats, but I wasn't wanting to type that much. IIRC, we normally test with 80 byte packets ... they can be UDP or TCP ... we're testing the routing. The box has two interfaces and we measure the number of PPS that get to the box on the other side. Without polling patches, the single processor box definately experiences live lock. Interestingly, the degree of livelock is fairly motherboard dependant. We have tested many cards and so far fxp's are our best performers. One of the largest problems we've found with GigE adapters on FreeBSD is that their pps ability (never mind the volume of data) is less than half that of the fxp driver. Terry I've never found this to be the case, using the right hardware, Terry and a combination of hard and soft interrupt coelescing. You'd Terry have to tell me what hardware you are using for me to be able Terry to stare at the driver. My personal hardware recommendation in Terry this regard would be the Tigon III, assuming that the packet Terry size was 1/3 to 1/6th the MTU, as you implied by your numbers. we were using the intel, which aparently was a mistake. We had a couple of others, too, but they were dissapointing. I can get their driver name later. Terry Personnally, I would *NOT* use polling, particularly if you Terry were using user space processing with Zebra, since any load at Terry all would push you to the point of starving the user space Terry process for CPU time; it's not really worth it (IMO) to do the Terry work necessary to go to weighted fair share queueing for Terry scheduling, if it came to that. The polling patches made zebra happy, actually. Under livelock, zebra would stop sending bgp hello packets. Under polling, we could pass the 150k+ packets and still have user time to run bgp. But we havn't tested every driver. The Intel GigE cards were especially disapointing. Terry Have you tried the Tigon III, with Bill Paul's driver? Terry If so, did you include the polling patches that I made against Terry the if_ti driver, and posted to -net, when you tested it? Terry Do you have enough control over the load clients that you can Terry ramp the load up until *just before* the performance starts to Terry tank? If so, what's the high point of the curve on the Terry Gigabit, before it tanks (and it will)? We need new switches, actually, but we'll be testing this soon. Terry If you are willing to significantly modify FreeBSD, and address Terry all of the latency issues, a multiport Gigabit router is Terry doable, but you haven't even mentioned the most important Terry aspect of any high speed networking system, so it's not likely Terry that you're going to be able to do this effectively, just Terry approaching it blind. We've been looking at the click stuff... and it seems interesting. I like some aspects of the netgraph interface better and may be paying for an ng_route to be created shortly. Terry Frankly, I am not significantly impressed by the Click and Terry other code. If all you are doing is routing, and everything Terry runds in a fixed amount of time at interrupt, it's fine, but it Terry quickly gets less fine, as you move away from that setup.

Terry If you are willing to significantly modify FreeBSD, and address Terry all of the latency issues, a multiport Gigabit router is Terry doable, but you haven't even mentioned the most important Terry aspect of any high speed networking system, so it's not likely Terry that you're going to be able to do this effectively, just Terry approaching it blind. We've been looking at the click stuff... and it seems interesting. I like some aspects of the netgraph interface better and may be paying for an ng_route to be created shortly.

Richard == Richard Sharpe [EMAIL PROTECTED] writes: Richard However, given that they were full 1500B frames (99%), at Richard least in one direction, perhaps that does not count. That's exactly the point. With large frames, you can get high rates of traffic. With smaller frames, rates drop quickly. We're using FreeBSD (with Zebra) as core routers for about 80Mbit of traffic to 3 main providers and about 25 local peers. We're facing the point where we have to decide to invest a little in the platform or ditch it for some name-brand gear. Much of the recent hacking on FreeBSD has been done in house and we recently hired another coder with kernel expertise to hack on the code. Of particular embarrasment is that FreeBSD produces source quench packets when acting as a router. Aparently an RFC made this a bad thing(tm) some time ago. Anyways... the average packet size at the core router is much smaller than 1500 with much of the traffic being in the tiny 100 byte category.

forwarded message on Source Quench Packets.
I normally wouldn't forward something to such a big list, but this has real implications (and was part of a nast DOS against dsl.ca last week). The patch for FreeBSD (netbsd code is quoted) is trivial: --- /sys/netinet/ip_input.c Thu Oct 17 08:29:53 2002 +++ ip_input.c Mon Nov 11 15:15:31 2002 @@ -1822,9 +1822,7 @@ break; case ENOBUFS: - type = ICMP_SOURCEQUENCH; - code = 0; - break; + return; case EACCES:/* ipfw denied packet */ m_freem(mcopy); I'm submitting a PR now. For discussion: source quenches probably shouldn't be generated anyways, but this patch also doesn't generate the source quench if we're the target machine. It's probably good to go straight ahead with this. IIRC, tcp_input.c also can generate a source quench ... ---BeginMessage--- On Mon, Nov 11, 2002 at 02:11:42PM -0400, richard's all...

As specified in Section [4.3.2], a router that does originate Source Quench messages MUST be able to limit the rate at which they are generated. DISCUSSION Research seems to suggest that Source Quench consumes network bandwidth but is an ineffective (and unfair) antidote to congestion. See, for example, [INTERNET:9] and [INTERNET:10]. Section [5.3.6] discusses the current thinking on how routers ought to deal with overload and network congestion. A router MAY ignore any ICMP Source Quench messages it receives. DISCUSSION A router itself may receive a Source Quench as the result of originating a packet sent to another router or host. Such datagrams might be, e.g., an EGP update sent to another router, or a telnet stream sent to a host. A mechanism has been proposed ([INTERNET:11], [INTERNET:12]) to make the IP layer respond directly to Source Quench by controlling the rate at which packets are sent, however, this proposal is currently experimental and not currently recommended.
