Re: Dragonflybsd's pf concurrent instead of single-threaded
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 There is 0 chance this works on OpenBSD. The underlying concepts that not only make it possible on Dragonfly, but actually useful are not there. As Henning Brauer pointed out, this makes no sense if the underlying subsystems arent taken care of first. However it does seem to make a difference on boxes with say 32 cores and a reasonable amount of memory. Provided the underlying systems are taken care of. the lwkt infrastructure mechanisms used here, are non trivial things, and are really the essence of the reason for Dragonflys original fork to begin with. Lets see lwkt, lockmgr, critical sections, atomic adds, pretty much a lesson in using dragonfly specific locking in this section of code. not to mention this is a pretty old version of pf, and is in no way current, with the pf in openbsd. Uprading pf with our set of changes to support our locking mechanisms, is a seriously non trivial exercise. trying to port this to a architecture without the underlying primitives would be a massive task.

Resume connetions of urtwn(4) - from zzz resume
Hi,
urtwn0 is a usb wifi connnection which work perfectly after bootup,
which got its configuration from /etc/hostname.urtwn0. But every time
resuming from zzz, it gets offline and need to online (sh /etc/netstart)
manually. Tried using /etc/apm/resume or ifstated(8) to execute sh
/etc/netstart in order to bring urtwn0 online but it doesn't work.
Instead, through /etc/apm/resume, ifstated(8) is able to bring urtwn0
online.
1. ifstated
ifconfig urtwn0 down after ifstated started (through
/etc/rc.d/ifstated) works correctly. But after resume, it doesn't seems
to do anything. /var/log/messages /var/log/daemon didn't show anything
useful to me. A /etc/rc.d/ifstated reload fixes it and it then does
its job, bringing urtwn0 online. A possible bug in ifstated or I've
mis-configured ifstated?
2. /etc/apm/resume
After resume from zzz, the command sh /etc/netstart in /etc/apm/resume
doesn't seems get executed at all, or some error happens but didn't get
recorded in /var/log/messages or /var/log/daemon. Tried set -x (made
/etc/apm/resume as bourne shell script) but nothing useful shown in
those logfiles. Maybe I've done something wrong here?
3. With ifstated through /etc/apm/resume
By reloading ifstated in /etc/apm/resume, it works accordingly.
Although this achieve my purpose of bringing interface urtwn0 online
after resume, the extra step taken to bring urtwn0 online seems awkward.
What seems to be wrong in what I've done in ifstated or /etc/apm/resume
that it doesn't execute sh /etc/netstart?
Below are my configurations and logs I've noticed. Please do let me know
if more information is needed.

Edward.

The window of opportunity seems to be closing. A penny for Henning's thoughts on this... my thoughts are only worth pennies? :) It's a kind thing to say, I think. :) ok, first thought: where's your diff? Not directed at Franco specifically. See below. I don't owe anybody anything. OpenBSD hacking is supposed to be fun for me. That's true. I'm not saying otherwise. on a technical note - making pf MP is utterly useless if the underlaying subsystems aren't. pool isn't, mbuf isn't, network stack isn't - the list is long. Exactly, the underlying cause for this: a lot of complicated subsystems need to be adapted. Some people have this on their ``list of things to do'' as stated a while back, but when there isn't enough incentive to work on this, at least for OpenBSD, it's hard to get started from the outside. The perfect code for the perfect SMP needs to be written and that's not something ``a diff'' from non-developers could easily accomplish. None of this is bad. OpenBSD will always be OpenBSD, no matter what. And the possible pf MP gains are drasticly overrated anyway. I'm not sure. Maybe that's a stance that fits OpenBSD well, but in networking as a whole that's not applicable. There's a good market for 10G, 40G not so much but it exists (as in drivers make their way into BSDs). Hardware vendors get ready for 100G; I've seen one of those cards and it does reveal a good deal of bottlenecks inside modern kernels. Yes, this requires specific mainstream architectures and PCIe 3.0, which is a small subset of OpenBSD system coverage. I can see that it doesn't make much sense from this point of view. That's where FreeBSD and DragonFly are a better fit. So maybe all that needs to change is the perception of pf(4) ports in other BSDs to be ``very old versions that need to be brought up to date'', because doing so wouldn't solve the most pressing issues we are confronted with pf(4) outside of OpenBSD -- the code itself is stable and the features are well-defined as is. Cheers, Franco

athn(4) may start in no carrier state when a failover trunkport
When using this hostname.trunk0:
---
trunkproto failover trunkport alc0 trunkport athn0
-inet6
dhcp
---
If the master trunkport is active on initial state, either at boot or
upon resume from suspend, on occasion the athn0 NIC shows no carrier.
Upon initiation of failover while in this state, it does not recover.
If the athn0 NIC is used as egress and not part of a trunk, it is always
active and never enters the same state.
A scan corrects the state, so this ifstated.conf has been implemented as
an attempted circumvention.
---
wifi_up = athn0.link.up
state only {
init {
if ! $wifi_up
run ifconfig athn0 scan /dev/null
}
if ! $wifi_up
run ifconfig athn0 scan /dev/null
}

Any recommendatons for better problem identifaction/isolation steps would be
appreciated.

multiple SSIDs with a single Wlan interface and 801.11.n support
Hello, I started to play with OpenBSD wlan interfaces lately and I've got two questions so far that I couldn't solve by myself: 1. Is there a way to create two SSIDs using one physical interface ? I'd like to create a public and a private SSID with different subnets and pf rules. 2. Is 802.11n supported on certain devices ? my Wlan USB dongle is detected as a Ralink 802.11b/g device (ral0) but in fact it's a b/g/n device. Thanks for your help Romain

previously on this list Maurice McCarthy contributed: I used to use and liked x-cdroast but have had more success with tkdvd lately which shows you the commandline that it uses too. Thanks for the tip about tkdvd. I only once tried K3B, because of the glowing reports it had, but just did not like it. But that was a while ago. Thinking about it now I think a different burning port segfaulted and simply used tkdvd because I didn't want to run the xcd-roast setup as root and was in a rush. tkdvd has a nopad option for cds which is the only reason I wanted k3b (I think can't pad though!) in order to be able to checksum the cd device file (verify and a security check in one pass) at any time matching the iso checksum. Padding is to get around a bug in some old recorders and whilst I have some drives that can't boot rewritables I have never come across this hardware bug requiring padding that most burning programs annoyingly enforce. -- ___ 'Write programs that do one thing and do it well.

py-pip for python3 on OpenBSD 5.5
Hey, So I'm currently trying to install pip for Python 3 on a 5.5 system. The port devel/py-pip has a python3 flavor which would theoretically allow me to do this. However, one of its dependencies (py-setuptools) does not, which is why I cannot install py-pip with the python3 flavor. What would be the best way to pip for Python 3 on the 5.5 release? Thanks Henrik
Re: Dragonflybsd's pf concurrent instead of single-threaded
Hi, Posting such a topic in such a list might probably sound a bit aggressive, but this patch should not be misinterpreted. I think it's clear to everybody that it would be great to update pf in dragonfly, but that's a lot of work and nobody is working on this. This patch followed a complaint on the mailing list about the slowness of pf on dragonfly, and I guess that making it SMP was the faster way (one day of work) to solve this issue. I don't think that anybody ever claimed that pf had become faster or better on dfly than on openbsd, or that openBSD is lagging behind. That being said, i subscribed to this list to reply to your last assertion. it's so obvious... two things needing to access the same data structures cannot run in parallel. packet filters CAN profit from MP, but it is way less than people keep thinking. This is obvious indeed, that's why the goal of this patch is to avoid the need to access the same data structures. This is due to the design of the dragonfly network stack. Packets are hashed, for instance with tcp they are hashed using the two tuples (host, port) for destination and origin, and they are dispatched to a fixed cpu according to this hash. The packet is then handled by this cpu, and the thread is pinned to this cpu. Things are more complex in practice due to hardware hashes, forwarding and other things i'm not an expert on the topic, but basically, it reduce the amount of sharing needed. You can take advantage of this design to make a packet filtering almost lockless. Indeed, you only need to access the local state for a lot of rules, and since the state structure is owned by the current cpu, you don't need any lock. (for nat/rdr or stateful firewalling, things are a bit less easy). In practice, this work as a real impact on my router, hence I really think that's nice to have, even if obviously having an up to date pf or good ipv6 support is more important (and a lot harder to do).

issues with firefox
Firefox becomes non-responsive for a small amount of time when viewing large (wallpaper sized) jpg images. In OpenBSD 5.4 firefox would block for several seconds. In OpenBSD 5.5 the situation improved considerably but it's still not perfect. The lag persists for a very short but visible amount of time. This bug is specific to OpenBSD and not to the machine, as i have tested it across different machines. This issue does not appear with other BSDs or linux (without flash). Secondly, viewing html video (eg in youtube) continuously lags. The sound is perfect but every other video frame seems to stop for a second or two and then the video jumps to the correct frame. This makes streaming video playback virtually unwatchable. This bug is specific to OpenBSD again. I have tested this at different machines and the result are the same. Once again, this issue does not appear with other BSDs or linux (without flash). Those two problems are much less obvious in OpenBSD-current's firefox, but, especially the second, still exist. I just wanted to report these issues and not complain. It is obvious that there is improvement at every new release of OpenBSD.

Maybe tokyocabinet would be a better fit, it might be worse to setup and I'm guessing it's not in the kernel ATM. See what I want to add to the kernel is this easy to use style of messaging so that common programs can use it, immediately. Like syslog is easy. I think libmessage would be a good fit it just needs a better backend. I think this is sorely needed, as well. A lot of bug tracking becomes much easier - I have seen ktrace. It is much like ktrace, yet can be used for applications too. It's like an internal network for the kernel.

Hi. I'm the maintainer of Racket on OpenBSD. Racket is a general purpose functional programming language http://racket-lang.org/ . Recently I began to port Racket to non-x86 platforms. The process is pretty simple when you know where the C macros are. The problem is that Racket fails always at the same point on hppa and mips64el (tested by jturner@). Matthew Flatt (the main developer of Racket) is interested in to take a look to the problem but he hasn't access to one of these machines (and qemu doesn't work). Can someone give us a shell account on one mips64/mips64el/hppa/sparc64/ppc/alpha machine?. The only requirement is at least 512MB of memory.

Re: libmessage (New crazy sh*t)
What you are trying is not new, but crazy and sh*t seem pretty spot on. Your description, not mine. There's even a wikipedia article dedicated to how dumb this is! From http://en.wikipedia.org/wiki/Database-as-IPC: In computer programming, Database-as-IPC is an anti-pattern where a database is used as the message queue for routine interprocess communication in a situation where a lightweight IPC mechanism such as sockets would be more suitable. Using a database for this kind of message passing is extremely inefficient compared to other IPC methods and often introduces serious long-term maintenance issues, but this method enjoys a measure of popularity because the database operations are more widely understood than 'proper' IPC mechanisms.[1] On Tue, Jul 08, 2014 at 06:59:57PM +0200, Gustav Fransson Nyvell wrote: mmap seems very low-level and dangerous ...

Please stop. think libmessage would be a good fit it just needs a better backend. No, it needs to disappear, and this conversation needs to end. The system you are proposing is not at all the system you need, nor the system you'd want if you understood the problem better. I think this is sorely needed, as well. Some other people have agreed with you, which is why this problem has already been tackled (in ways MUCH better than you are proposing) by people who put actual thought into the design phase before writing the dozens of different messaging queue/bus systems out there. A lot of bug tracking becomes much easier - I have seen ktrace. It is much like ktrace, yet can be used for applications too. It's quite obvious that you have no idea what you're talking about. It's like an internal network for the kernel. First of all, this has nothing to do with networks. Second of all, this has nothing to do with the kernel. I know that message queues are frowned upon yet they are very UNIX, remember JMS is from Java which is from Sun, which you know... created Solaris, SunOS? UNIX is supposed to be big and slow. Good bye, troll.

Re: issues with firefox
Is GPU acceleration supposed to work in Firefox on OpenBSD? I'm just checking about:support and can see 0/1 in GPU Accelerated Windows. In the meanwhile, Chromium is fine (according to chrome://gpu). On a side note, smtube is a very nice solution to playing YouTube videos. Installing gecko-mediaplayer (http://www.lounge.se/wiki2/show/FlashOnOpenBSD) has also improved the performance of video in Firefox a little bit for me.

Re: crowding out bsd using systemd?
Please ian, I'm not crititsizing you, or your poject. Perhaps this is a bad quality, but I'm one of those people who don't like incomplete links (and that is what is I'm crititsizing.) I expect to click on a link and voila, there is the web page I'm looking for. Of course, I could look for the corect one, but I'm assuming that other people are far lazier then I and they may not want to go through the trouble (and so they need a complete link.) I thought that as it is your poject you'd have a book mark or similar availible at a moments notice. I originally tried a search but your name (ian kermlin) is on none of the projects (which is highly confusing.) Here, I'll post a link for you; is it: http://www.openbsdfoundation.org/gsoc2014.html#systemd ? Thanks, David PS: As you requested I've cloned the repo git://uglyman.kremlin.cc/git/systemd-utl.git I'll look over the code for you.PPS: I've not quoted your previous post as I suspect I caught you at a bad moment and this is a public and archived mailing list.

Is there any (proper and automatic) way to avoid that ? I know that kind of situation will not happens often but... Thanks again!

I find ifconfig(8) inconclusive; run your own tests and if that works, you have a built-in solution for keeping all the carp interfaces in sync. Then, use ifstated to manage the pppoe interfaces depending on ifstate of the relevant wan interface? You could set up a carp interface with no IP address bound, set it into the common if group and it would go up/down with the other carp ifs. Maybe. I haven't tried anything like that myself. -Adam I run some tests and this is working as expected! Only thing I see is that there will be no group failback if this is a virtual carp interface which goes down. To be clear if the parent interface of carp2 goes down the whole group will switch but not if carp2 goes down by itself (by an admin mistake for example): * initial states root@obsd1:~# sysctl -a|grep preem net.inet.carp.preempt=1 root@obsd1:~# ifconfig HA |grep status status: master status: master status: master status: master root@obsd2:~# sysctl -a|grep preem net.inet.carp.preempt=1 root@obsd2:~# ifconfig HA |grep status status: backup status: backup status: backup status: backup * states with carp2 down on obsd1 root@obsd1:~# ifconfig carp2 down root@obsd1:~# ifconfig HA |grep status status: master status: master status: invalid status: master root@obsd2:~# ifconfig HA |grep status status: backup status: backup status: master status: backup * also unfortunately when carp2 goes UP again on obsd1 it still remains on obsd2: root@obsd1:~# ifconfig carp2 up root@obsd1:~# ifconfig HA |grep status status: master status: master status: backup status: master root@obsd2:~# ifconfig HA |grep status status: backup status: backup status: master status: backup Anyway I think this is an acceptable risk. @Adam: I will now try to use ifstated to manage pppoe interfaces like you suggest. Thanks to everyone of you.

Actually GENERIC.MP performs better than GENERIC.SP. I have discovered through experience that the more powerfull a processor is, the less these problems appear (using GENERIC.MP). Trying to view a youtube video on an atom-based netbook is impossible, while doing the same on a i3 core computer is more or less ok.
