Random kernel panics when using a Blu-Ray drive
I installed a Blu-Ray drive into my OpenBSD desktop today (running May 13th amd64 snapshot) and have been playing around with it some. However, somewhat regularly running disklabel cd1 or mount /dev/cd1a /mnt causes a kernel panic. I've seen it happen with both DVDs and Blu-Rays, though I haven't yet seen any panics while accessing files on an already mounted disc. The most recent kernel panic output was: panic: kernel diagnostic assertion xa-state == ATA_S_SETUP failed: file ../../../../dev/pci/ahci.c, line 2354 Stopped at Debugger+0x5: leave RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!

Re: A codec with a BSD Licence
Rod Whitworth P?P8QP5Q: I saw news that told me that Google was opensourcing the VP8 codec and using it on Youtube. The good news is that the licence is a BSD style one, http://www.webmproject.org/license/software/ and they require contributors submitting code to agree to it being distributed with the same terms and for the author to grant free use with no patent fees etc (http://code.google.com/legal/individual-cla-v1.0.html) before code will be accepted by Google. So we should be able to use it and not have to worry about the flasher junk. Hopefully I will be able to watch OpenBSD devs' presentations at conferences that are out of reach for me, in better video. The slides are best for reference but the action shots and off-the-cuff comments are great and sometimes very funny. So, on the day of OpenBSD's latest release there comes a BSD licenced codec. http://x264dev.multimedia.cx/?p=377 R/ *** NOTE *** Please DO NOT CC me. I am subscribed to the list.

Re: Random kernel panics when using a Blu-Ray drive

With some luck, maybe it's of some use to someone with actual knowledge of how SCSI, AHCI, et al actually fit together. I've found the most reliable way to kernel panic is to insert a BD, and then run disklabel cd1 repeatedly while the drive initially scans the disc. (Simply running disklabel cd1 if the disc was already in at boot time doesn't seem to trigger it.) Immediately after running the last disklabel cd1 command before panic, in the kernel output I get: ahci0.3: ahci_ata_get_xfer got slot 17 ahci0.3: interrupt: 4001TFES,DHRS ahci0.3: error slot 17, TFD: 6851ERR, SERR: 0, DIAG: 0 (At this point xa-state is set to ATA_S_ERROR on line 1862 of ahci.c.) ahci0.3: slot 17 is complete (error) This error propagates back to scsi_xs_sync, which calls scsi_xs_error to interpret the error. This calls scsi_interpret_sense: cd1(ahci0:3:0): Check Condition (error 0x70) on opcode 0x0 SENSE KEY: Unit Attention and eventually falls through to calling scsi_delay on line 1473 of scsi_base.c, which returns ERESTART. Finally, scsi_xs_sync then loops calling scsi_xs_exec again with the same (now errored) xs it got from scsi_scsi_cmd, which eventually reaches ahci_ata_cmd and kernel panics because xa-status == ATA_S_ERROR. Anyway, that's where I'm stuck.
Re: How to work around this compiler bug
Hi,
I got another problem compiling some strange C++ code with gcc
3.5; still from opal:
std::string a(std::string(A::Class()));
results in:
error: cannot use `::' in parameter declaration
the actual code in opal looks like this:
#define OPAL_DEFINE_COMMAND(command, entity, func) \
class entity##_##command : public command \
{ \
public: virtual void Process(OpalPresentity presentity) {
dynamic_castentity (presentity).func(*this); } \
}; \

s_entity##_##command(PDefaultPFactoryKey(entity::Class())+typeid(command).name())
I have no clue what this is actually about. So I would be really
happy if someone could help me out in changing this piece of code
into something gcc 3.5 understands.

Resilient RAID
I need an inexpensive OpenBSD system that will survive a disk failure, to act as a firewall. My understanding from the on-line documentation and the list archives is that the new RAID system, softraid, does not support having the root partition on RAID meaning that if the system disk fails the machine crashes. Is this (still) correct? If so, the installation notes for 4.7 suggest against using RAIDframe (and even mis-spell the hyperlink!), which raises two further questions: What is the most recent OpenBSD release that does support and document installing on to RAID? Should I install that version or am I best off trying to adapt its installation instructions for 4.7? Thanks John

Hey, I could work around this issue. Thanks for you help so far!!
If you are interested see below.

There's no gcc 3.5.
ok, that's true, its 3.3.5 of course.
std::string a(std::string(A::Class()));
results in:
error: cannot use `::' in parameter declaration
gcc 3.3.5 can't understand chains of constructors relying on temporaries,
use intermediate variables.
I think I got that.
e.g.,
A::Class tmp;
std:string a(tmp);
Class() is a method of every class in ptlib/opal, which just
returns a string as identifier for that class. (See below for the
code)
So declaring A::Class tmp does not really make sense, does it?
(the double std::string is non-sensical, btw)
As I said, I tried to strip down the offending code as much as
possible to find out what the compiler is actually complaining
about. The original snippet of code looked like this:
SNIP ===
#define OPAL_DEFINE_COMMAND(command, entity, func) \
class entity##_##command : public command \
{ \
public: virtual void Process(OpalPresentity presentity) {
dynamic_castentity (presentity).func(*this); } \
}; \
static PFactoryOpalPresentityCommand::Workerentity##_##command \
s_entity##_##command(PDefaultPFactoryKey(entity::Class())+typeid(command).name())
SNIP ===
As I understand it now, the compiler would need to create a
temporary instance of 'entity' to make the call to ::Class(), but
gcc 3.3.5 is not able to do this?
I now tried to fix it this way:
SNIP ===
#define OPAL_DEFINE_COMMAND(command, entity, func) \
class entity##_##command : public command \
{ \
public: virtual void Process(OpalPresentity presentity) {
dynamic_castentity (presentity).func(*this); } \
}; \
entity tmp; \
static PFactoryOpalPresentityCommand::Workerentity##_##command \
s_entity##_##command(PDefaultPFactoryKey(tmp.Class())+typeid(command).name())
OPAL_DEFINE_COMMAND(OpalSetLocalPresenceCommand, OpalPresentity,
Internal_SendLocalPresence);
SNIP ===
this doesn't work because:
`OpalPresentity::OpalPresentity()' is protected
within this context cannot declare variable `tmp' to be of type
`OpalPresentity' because the following virtual functions are
abstract:
virtual bool OpalPresentity::Open()
virtual bool OpalPresentity::IsOpen() const
virtual bool OpalPresentity::Close()
I'm willing to help, but can you at least double check what you type ?
Now anyway this is where the ::Class() method is defined:
SNIP ===
#define PCLASSINFO(cls, par) \
public: \
typedef cls P_thisClass; \
static inline const char * Class() \
{ return #cls; } \
SNIP ===
Since PCLASSINFO gets called with the 'OpalPresenty' as parameter
for 'cls' I could just remove the 'entity::Class()' thingy and
replace it by '#entity':
SNIP ===
#define OPAL_DEFINE_COMMAND(command, entity, func) \
class entity##_##command : public command \
{ \
public: virtual void Process(OpalPresentity presentity) {
dynamic_castentity (presentity).func(*this); } \
}; \
static PFactoryOpalPresentityCommand::Workerentity##_##command \
s_entity##_##command(PDefaultPFactoryKey(#entity)+typeid(command).name())
SNIP ===
g, that was too easy. I tried to fix this for several days
now. Sometimes you just need to know where to look.
Anyway thank you very much for your inspiration ;)

Re: Resilient RAID
What is the most recent OpenBSD release that does support and document installing on to RAID? none. it's pointless anyway. use two machines and carp, et voila, resilent against a lot more things than just disk failures.

Re: Resilient RAID
If your firewall has to run in not so hostile conditions like sub-zero temperatures or large temp differences over short time (typically right under the roof), consider using flash memory (CF-ATA converters being available around 20 USD) instead of hard disk + eventually mfs for some logging or so. We're running and know about hundreds of settings like this without any serious problems and very minimal percentage of failures. 2010/5/20, Henning Brauer lists-open...@bsws.de: * John Rowe r...@excc.ex.ac.uk [2010-05-20 16:02]: I need an inexpensive OpenBSD system that will survive a disk failure, to act as a firewall. wrong approach, see below My understanding from the on-line documentation and the list archives is that the new RAID system, softraid, does not support having the root partition on RAID meaning that if the system disk fails the machine crashes. Is this (still) correct? yes. it'll change eventually.

One pseudo solution is to run a bridge instead of trunk on the 2 interfaces and use STP for fail-over; I find that too yucky to solve a problem that doesn't really exist (just buy a reliable switch with a redundant power supply or connect the single one to a good UPS) However, if you need to ask if you can run a trunk on top of a carp, do yourself a favor and use a single switch.

Trying to do the same all the way to the end hosts (i.e. without a routing protocol) is pretty difficult. i would never ever run any L3 on switches. Bad wording on my part, the routers run OSPF and the switches are dumb L2 devices. Still, without OSPF et al there would be no way to detect a crappy switch failing in funny ways, which was my point. As an extra note, if you do get a crappy switch, be very careful with its management interface. The cheapest ones have unbelievably slow CPUs that are easily overloaded by broadcasts making the whole thing stop responding. Even worse, the interrupt load seems to trigger some other bugs, like LACP mysteriously failing and disabling one port on a trunk and blackholing half of your traffic (this happened on a ZyXEL GS-4024, which has otherwise totally Just Worked as a L2 switch for years) or even the whole switch ASIC crashing after a broadcast storm and requiring a reboot (though the management CPU was still responding through the out of band ether and serial port after the storm was gone) Also, it's a very obvious DoS; a malicious person needs to send a rather small amount of BPDUs to overload the tiny CPU and the cheap switches obviously have no rate limiting for packets going to the CPU (only on all broadcasts). So, blocking BPDUs from non-trusted devices should be enabled (but that should probably be done anyway.) Even among trusted devices STP and LACP involve the shitty code running on the underpowered management CPU, and that is not the part that shines in the cheap switches. Static link aggregation works OK.

Re: HA: pair of firewalls, 2 switches and 1 server
I do this too. In addition to the previously mentioned problems with cheap switches losing their configs (and vlans) you should make sure the active interfaces are all on one switch so that the link between them isn't uselessly used; this will also avoid an unpleasant split brain event if that link ever happens to fail. But in this case you will also have to very carefully check the other switch stays properly configured so the backup interfaces will actually pass the traffic you want. Linux's bonding module has an arp monitor which solves some of these problems, but the implementation is so hackish (as usual there...) that I'd rather not use it in production. arping and ifstated might do the same on openbsd, but I'm not sure if that will work when the interfaces are trunk ports. I'll need to check this when I have time.

OpenBSD 4.7 as VPN Gateway for Road Warriors, Preferred Configuration
Hey guys: I'm looking for a little direction here, as the preferred method of setting up a VPN for these types of connections seems to have changed many times throughout the version history of OpenBSD and changes to IPSec, isakmpd, pf, etc.. So as you've probably gleaned from the subject, I want multiple clients to be able to connect to the OpenBSD 4.7 VPN Gateway. I'd also like to use DHCP over IPSec. I've found many examples via Google. Some are using isakmpd.conf, while others use the isakmpd -K switch and defer to ipsec.conf for configuration. In my situation with multiple Road Warriors, is one way more correct than the other..? Easier..? What's the preferred method in the day of OpenBSD 4.7? Thanks, don..

I'll need to check this when I have time. why not? trunk is just a normal ethernet interface. the linux bondage trick sounds hackish, but link detection protocols like udld or bfd should help here on the ethernet level. many managed switches support one of these protocols and i'd like to do this on the openbsd side at some point to alter the link state based on optional uni-/bidirectional link detection. reyk

It doesn't matter all that much since the above tells me the device is most likely usable in OpenBSD as is. Two of the three umodem(4) have serial ports attached (ucom(4)) so all you need to do is configure ppp(8) or pppd(8) to talk to one of those serial ports (/dev/cuaU?). You should probably read the umsm(4) for more info and an example chat script. A lot of similar EVDO/HSPA devices are built in the same way in the sense of providing more than one serial port, but only one of them is usable with ppp/pppd. The other supposed serial port speaks a proprietary protocol and is used for management purposes. Typically, the proprietary protocol is either Qualcomm QMI or Qualcomm DM. Due to various leaks (read: google android), portions of the proprietary protocol have been figured out by the linux camp, but it's still a work in progress.
