Re: Real time programming in OpenBSD

What I'm looking for is simple way to take advantage of high quality and secure code base of OpenBSD to use in real time/embedded applications. If this trick can be achived, it is simple to use OpenBSD as platform when critical parts of software can run on own CPU core and rest of the software can developed conventional means. If this can be done, or this kind of feature may be noted and put to roadmap, I may have motivations to audit time requirements of library functions etc. and formally verify parts of the system. You can use this diff if you want, it adds support for nice(1) to do the binding, I use it to do MP tests. https://github.com/haesbaert/bitrig/commit/c0d5adb6ee5f3b77e17254c6eaf0e02333b30d8b

Re: Very slow I/O under OpenBSD i386 on qemu-kvm from RHEL7rc
On 16 June 2014 04:19, Mikolaj Kucharski miko...@kucharski.name wrote: Hi, Please CC me in any replies as I'm not subscribed to misc emails. My main question is, do you experience similar slow I/O on OpenBSD i386 on your Qemu/KVM installations? Are you aware of any problem with OpenBSD i386 under Qemu/KVM? Not sure should this report go to RedHat, KVM or to OpenBSD, but I've tested RHEL7rc with CentOS 6.5, NetBSD 6.1.4 installer and OpenBSD current bsd.rd and only OpenBSD i386 seems to have slow I/O problem under latest Enterprise Linux from RedHat. I've decided to report the issue here. I've tested OpenBSD guest with IDE, SCSI and VirtIO disk. SCSI disk currently don't seem to work at all with both amd64 and i386: The problem is the i386 ioapic/apic implementation and how OpenBSD uses the lapic_tpr to block incoming interrupts. Basically if you're using ioapic (and you are), OpenBSD maps the lapic_tpr to the special TPR register to block interrupts everytime you get an interrupt of raise it yourself by splraise()/spl* and so on. You don't suffer this on amd64 since the masking is done purely in software. You can also verify this statement by disabling mpbios on OpenBSD and falling back to the old pic controller, in this case you don't use ioapic, and the pic code does the mask in software, lapic_tpr is still the same variable being touched, but in this code path, it's not mapped to the cpu TPR. To have an ideia of the cost of touching the tpr: real hardware: ~25 cycles. kvm + flexpriority (cpu extension): ~2700 cycles. kvm without flextpriority: 100k+ cycles. So every interrupt you take needs to touch at least lapic_tpr twice, which before would cost ~50cycles, and now it's more than ~200kcycles. Of course these numbers are relevant to the machine I've tested, but you get an idea on how much slower it is.

Re: openbsd 5.2 amd64: high interrupts/low throughout problem: Intel 10GBE cards, dual xeon x5570 (dell r710)
On 13 June 2013 00:15, John Jasen jja...@realityfailure.org wrote: (We've seen this problem through a few OpenBSD releases. 5.2 is much improved over 4.8 in this regard. Using BIOS to disable multiple cores on each physical CPU also yielded greater throughput. Hyperthreading and virtualization BIOS extensions are off.) We have two Dell poweredge 710 systems in an active/passive carp failover configuration, acting as firewall systems, with another one currently being used for testing. Various tests show the system can handle close to 10GbE speeds in and out, but I've not been able to push much beyond that, hitting a wall at about 11-12Gb/s. That is more or less what you will get on OpenBSD. As I try to push the test system, interrupts climb above 12-15k/second (seen via systat), consuming more and more of the first CPU until after about 50% utilisation (according to top), it just hits a wall and refuses to spit out any more bandwidth. A coworker was able to drive it up to close to 60k interrupts/second, but was not able to get much more through it. Comparison tests, booting a Debian Squeeze live cd, and booting FreeBSD 9.x, indicate that out of the box, they can push 15-20Gb/s -- which, while lower than what I would expect, is an improvement. Here your test is probably botched, you're probably just stressing one queue from the card, which gives you more or less what you're seeing, you need to send multiple tcp/udp streams, then you can have an idea how much linux/freebsd can do. obs: we usually count forwarding rate, so when you say 15gbit/s, most people say 7.5gbit/s =) Are there tuning options that we've not seen yet? Googling, reading the ix(4) manpage have not exposed a clear go faster option, and I'm concerned about the load and interrupts concentrating on one CPU so heavily. OpenBSD kernel is single threaded so this is the expected behaviour. ifconfig (from test box, minux carp and vlan interfaces) and dmesg enclosed.

De : Maxime Villard rusty...@gmx.fr
Pour : t...@openbsd.org
Hi,
here are my small changes for pfctl.
1) There are cases where we could leak a file descriptor by
returning.
2) We don't need to check memory before freeing it, as
free() already does that.
3) Just replaced a snprintf() by strlcpy(), it's faster.
Ok/Comments ?

Re: Calomel.org
I feel this usually comes from folks with Linux background. You see, in BSD world, specially in OpenBSD, there is good and high quality documentation, which the developers put a lot of effort in providing it. I know, since I did it too in the past, that when you're using Linux, you're basically in the dark, so you go to google, and you try your luck. Everytime you follow a non official documentation, you waste your time and the developer's time, we're not cranky about calomel only, we're cranky about people following unofficial documentation, remember, our FAQ and manpages are accurate 99.99% of the time and they are pretty well written and complete. If you can't figure it out by reading the FAQ/manpages: you're either not ready for it, or we have a documentation bug.

Did you go into your phone settings and enabled USB Tethering ? it presents an ethernet-like interface, normally you would run dhclient on a computer to connect via the phone - the computer will then use the phone for internet access via whichever method it's connected, wifi/3g/gprs/etc). Howeverit's just a network interface, so I imagine that if you have access to change the phone's routing table (which will probably require the phone to be rooted) then I don't see why you couldn't change the default route on the phone...

OpenBSD web page: - It's small - It's simple, just basic HTML, some cgi, nothing fancy, all very easy to maintain. - You find anything in less than 1 minute. - It looks nice, since that is how webpages should look like (IMHO).

Actually, before a webserver, I'd recommend learning how to write a shell as it will have you deal with lots of concepts you would not see otherwise ... then network programming :-p Yep shell is a good example. One small task I used to pass to people wanting to learn C, is to implement a strtok-like function, they could design their own API. It is interesting because they need to deal with pointers, strings, and design an API as in: - should I pass a fixed array and alloc all tokens ? - should I return an alloced structure ? - should I modify the string in place as strtok ? should I copy. A lot of decisions have to be made, and it's interesting to see how they approach it.

Hello,
today I'm proud to release the first public version of portable cwm 5.1.
Portable cwm is a minor modification of the cwm version in OpenBSD CVS
with a portable Makefile and a few compatibility features. It has
been built successfully on OpenBSD, NetBSD and Linux.
This port requires pkg-config, Xft, Xinerama and Xrandr. The included
Makefile should work with both GNU make and BSD make.
This version actively tracks changes in the OpenBSD CVS repository.
Releases are roughly coordinated.

Thanks for the port, I had to tweak a bit to compile on an ancient

On 27 February 2012 16:38, Kaya Saman kayasa...@gmail.com wrote: Hi, this is my first posting here :-) I have currently only used OpenBSD as a test vector setup on VirtualBox and 2x Sun Fire V240's as a DNS server (master/slave) using Bind9. So basically in short am an OpenBSD newbee :-) Ok so here goes; I've been using FreeBSD for around 3+ years now and really enjoy it, in comparing OpenBSD to FreeBSD I first would like to get some user experience of the major advantages over it. From my reading it's meant to be more secure, from my (vastly) limited experience it's quite different to work with then FreeBSD. -Could anyone give me any summarized answers to compare the two? Now here comes the major project For the last past 4 years or so I've been hosting various OpenSource projects from home and have a setup similar to the OpenBSD rack pics on the openbsd.org site :-) To fill the role of router I have used till now, a Cisco 857, 877, and 1801 all of who's power I've managed to max out!! :-( As a qualified Cisco engineer but also budding UNIX engineer/enthusiast I've come to understand that Cisco boxes are underpowered and overpriced Graphing the Cisco's using SNMP and RRD tools using Cacti, the CPU's tend to max-out after the TCP/IP flows start reaching 1000+ and so goes the memory too. Then I loose all kind of connectivity as the router either crashes or becomes unstable. So I would like to build a router out of a Quad Core Xeon system. I've selected the hardware for it already and the software barring the base OS. You want the highest cache and highest frequency cpu you can find. MP will not help you with routing performance at all. The hardware will run a socket 1366 Xeon using a Supermicro system board. (I'm sure this will be 100% compatible with OpenBSD or FreeBSD whichever I chose) http://www.supermicro.nl/products/motherboard/Xeon3000/X58/X8SAX.cfm Additionally I would like to run a 5.25 LCD in the chassis front to monitor on the fly system output using Lcdproc - this is available on FreeBSD using ports but not sure about OpenBSD though I'm sure can be easily compiled if necessary. Something like the PicoLCD from Mini-Box or Matrix-Orbital displays or similar. --actually I think VFD's are kinda cool but need to find a 5.25 one :-) I also would like to know if anyone knows of any ADSL2+ Annex M standard PCI (/x/) based modem card that I can use to connect to my ISP with instead of using an external device? So far in my search I came across this: http://linitx.com/viewcategory.php?catid=47 Of which manufacturers seem to be: http://www.rocksolidelectronics.com/pages/products.php Are these going to be OpenBSD compatible or are there others??? Does anyone know of a VDSL2 solution like this also? For software I plan to use Quagga/Zebra which should be in the ports or compatible easily coupled with NAT, ACL's, Firewall using PF or so In OpenBSD there are actually usable routing daemons, OpenBGPD, OpenRIPD and OpenOSPFD. In this case comparing FreeBSD, what's OpenBSD's performance like for Firewall/IDS/IPS systems?? That's something only you can test, there are tons of variables in place here. Is OpenBSD compatible with Cisco VTP and STP to trunk VLANs to Cisco switches? I'm not familiar with VTP, the rest will be fine. I did discover this already: http://fengnet.com/book/icuna/ch05lev1sec5.html so it would seem so, however I do not know if link-aggregation would work?? As in Cisco Etherchannel to multiple ports on the router. Yep, trunk will work fine with a cisco. There are many more questions I have but will refrain from asking at this phase as most of them can be got round by researching; like Cisco IPSEC/GRE VPN compatibility et el. i think am just worried about the ADSL2 modem card mainly as most of the above can be got over with testing and trying things out :-) It's just a pain that a Cisco 2901 for example as claimed by Cisco can only route at 75Mbps (ok routing uses PPS but wirespeed is not available unless going carrier grade). Especially now that companies are slowly starting to release Residential Fiber networks upto 1Gbps... would render the Cisco's maxed-out power wise. With a decent hardware, I think you can reach 1mpps (that's million packets per second). I know there are a lot of questions here but am hoping that some of them can be answered or at least advise given pre-testing :-) Many thanks and best regards, Kaya Good luck

And what would be amd64, wow I had no idea such cpu was out already, I'm not sure if anyone ever tried running openbsd on such cpu. the benefit for having multi CPU sockets or cores??? Almost none for routing purposes, the kernel is big locked and all interrupts go to cpu0, so this basically means: You'll be routing packets on cpu0 *only*. But you'll get the benefit of of having the userland processes running on multiple cpus, so if you're basically routing/filtering with pf, MP won't make much difference. --I mean for an integrated Firewall/router yes one can offload processes and threads per core or socket Userland process will benefit from MP when running in userland, they'll get the biglock when doing a system call. You only have one process running in kernel land at-a-time. With this though I'm betting that a Core2Quad Q8400s CPU (which I currently run on a FreeBSD based Mini-NAS mainframe) will be more powerful then any Cisco SMB based router? - I can see it being more powerful then my 8xx or 18xx series in anycase! I don't know cisco, it's all about how much data you need to route. But if you were concerned about 75mbps, even my sun ultra 5 400mhz can do more than that. Do the math, I'd guess you can do *at least* 300mpps with any fairly modern cpu. Now do 300mpps * 1500bytes, that's your throughput for full sized packets. You may want to read this: http://www.undeadly.org/cgi?action=articlesid=2011101406 Most DIY/Linux router boxes all seem to run Mini-ITX hardware on Intel ATOMs or VIA processors or Vyatta running standard x86 Multi-core architecture for their appliances; how does this relate to the equation? Those are very weak processors, again, it's all about how much pps you need.

Some network cards support IP checksum offload. Packet headers for
such
interfaces erroneously indicate a bad checksum, since the checksum is
not
calculated until after tcpdump sees the packet.
so maybe related to your case
I think that is not the case here, by default we do not enable em(4)
checksumming offload.
Just to make sure, can you give me the output of 'if config

I think pf is not recalculating the checksum after nating, not sure if

You forgot the definition of answer{}
struct answer {
char name[2];
u_int16_t type;
u_int16_t class;
u_int32_t ttl;
u_int16_t rdlength; /* 12 */
char rdata; /* 12 + 16 */
} __attribute__((packed));
The thing is that GCC knows rdata is 1 byte long, you're doing the
magic here if I'm correct:
/* skip dns header, question name, qtype and qclass */
answer = (struct answer *)(reply[0] + sizeof(struct dns_header) +
q-hdr-namelen + 4);
You can remove the __attribute__((packed)) and turn rdata into char
rdata[].
Or just get a pointer past sizeof(answer).

Hi again,
Could you try the following diff ?
Please remember to undo the modifications of the previous diff.
The thing is in_proto_cksum_out() correctly escapes hw checksumming if
the interface is a member of a bridge, the same should be done for ip

You don't want a cheap NAND flash with JFS2 mounted rw. for the scenario i had in mind - servers in some data center - that is the one solution. Agreed. Many posts ago, BTW, so why do you still bring it up? I specifically differentiated between devices that store and devices that do. Data center servers which have baby sitters in an office nearby don't need automagic thingies. I don't buy the countless at all, we're really only talking embedded here, and for embedded style use cases you'll have to adopt. that is the special case and not the norm. Embedded systems with configurable settings are a special case? Where were you during the last 10 years? while i was mostly talking about a console and not fsck -y, i do believe that an automagic fsck -y is pretty damn stupid. Guess what your home router does, and what (if you have one) your cell phone does? Also your car and your TV set? None of these drop you into a console after the 3rd power outage and people would laugh you out the door if you tried to sell such a product. while we're really good in that and fsck almost always succeeds and fixes things up i have seen different. And most likely the problems were not caused by fsck but by faulty hardware creating the mess to begin with. No serial console can fix faulty RAM chips, itchy power supplies or loose SATA cables, so it wouldn't help the proud owner of a do device one bit. As I have written before: I don't care whether the default install of OBSD comes with fsck -p or fsck -y, but calling people who suggest fsck -y in certain situations cheapskates and stupid shows blatant ignorance.

I've started using OpenBSD in 4.2 and been upgrading since them. I *never* had an issue. There are a lot of people out there doing since much much much older releases. Insan: As for the original question, no, you should have no problems. We all run a bunch of amd64 machines and upgrade it constantly, if not daily. Please report back if you have any troubles.

Re: Packet drop because of invalid IP checksum on Soerkis / vr / ral
I think I've found the problem. when a packet comes from ral0 --- 10.0.0.1, the bridge changes the received interface to vr0, which has IFCAP_CSUM_IPv4. So when the icmp layer is about to test the checksum, it assumes the output interface is the same one which the packet came in (in our case, vr0, and not ral0). So the checksum does not get calculated. That's why it works when we remove the capabilities from vr0.
Re: Something similar to Soekris boards, for server applications
On 30 November 2011 14:27, Sime Ramov s...@ramov.com wrote: Hello, I am looking for something in the spirit of Soekris boards, but more suited for server applications, e.g. for hosting Django apps. Current net6501 is maxed out at 2 GB of RAM and 1.6 Ghz *single-core* (two threads) atom. The reason I am considering Soekris is because dedicated servers are often underused and idling. Few GB of memory, anemic processor and SSD gets one a surprisingly long way, especially with properly chosen stack and caching. So the general idea is: one Django app = one Soekris board. This is much better than virtualization (bare metal forever) or putting more apps on a big server. Some apps would run great on this, but a more powerful CPU and more memory would be needed for more demanding workloads. Any recommendations for similar, but a bit more powerful and versatile hardware (think one app = one hardware device)? Thanks. You may consider the new AMD E-350, the fusion ones, they're very low-power and might suit you. They're very, very cheap, I've never used them, but sounds a better alternative than the atom.

Re: Help setting up a PF NAT gateway

These are my first and only NAT rules. The other rules work fine and are just to allow SSH to my management interface and ICMP response from the external IP and from the internal gateway IP. Besides I've removed the block all so the other rules don't matter much now. match out on vic2 inet from 10.221.181.0/24 to any nat-to (vic2) round-robin pass inet from 10.221.181.0/24 to any flags S/SA keep state With tcpdump I can see packets going to vic3, but no further. With block all commented out I can fully test the network around and everything is working just fine, I can nc -kl 50.50.50.59 65535 and connect to that port from anywhere on the internet. I just can't connect out from the private network through the gateway. The systems in the private network have 10.221.181.10 as their default gateway. I even have the Book of PF 2nd edition here but it's of no use, the rules are mostly from there. Just for troubleshooting I can also nc -kl 10.221.181.10 65535 on the gateway and connect to that port from the private network machines without issues. So please tell me, what am I missing in this nat-to rule? Hi, can you paste your pf.conf ? The output of ifconfig would be good too.
Re: Help setting up a PF NAT gateway
On 10 October 2011 15:05, Stefan Midjich sweh...@gmail.com wrote: That was from the output of pfctl -vf /etc/pf.conf so it expands the rules and adds all that is implied, like keep state for example. I think that is not what you want: match in on vic3 inet from 10.221.181.0/24 to any label NATOut nat-to (vic2) round-robin You want to match packets going out your external interface, and then nat-to the external interface address, so try something like: match out on vic2 inet from 10.221/181.0/24 nat-to (vic2) Considering vic2 as your external interface.

I think sbchecklowmem() may be failing in uipc_socket2.c:403.

Re: Time interval based pf rule

So Time interval base rule means: user is only allowed to access specific application and destination based from the time interval. For example: Finance Department user is only allowed to access facebook website after office hour (after 6PM onwards) and only on friday. If I didn't add the time interval, they can spend their time for browsing and chatting on facebook instead of working. What do you mean by one-hit rules? Rules that get destroyed after a first match, but that's not what you want. anchors + crontab as Peter suggested is an easy alternative.

speakers, but still no sound.

Re: Laffs with Lennart
Lennart is a funny, funny man, go check the avahi code to see how nice it is. When working on Avahi I learned a lot about the complexities of safely and reliably running and maintaining system services, and about securing them as much as possible, which is particularly important for network facing services like Avahi. I implemented a lot of pretty nifty features in this area in Avahi. For example, Avahi is still pretty much the *only daemon* on a standard Linux install that chroot()s itself by default. -- Christiano Farina HAESBAERT Do NOT send me html mail.

Hi Christiano, you don't specify where the IPv4 host is (local network or outside), but I did some playing with faithd(8) in the past and think you may want to check it out. You just have to be careful not to let outside v6 traffic in to faithd as it could be used for proxying (good pf rules needed). When I used faithd it was to translate from a FreeBSD jail which only spoke v6 to a FreeBSD jail which only spoke v4, I remember being satisfied with the test results then, even though it was on FreeBSD. Cheers, -peter Great, but gif(4) will be enough, I changed some things, so now I only need the ip6-ip4 tunnel. Thanks a lot.
