synchronous freebsd print
Hi, I have a quick question, and I believe this will be a common requirement. I do a print of some data and then immediately in a next statement there is a crash. But the print is not complete, before it completes there is a crash, the print is about 6-9 lines . Is there anyway to get the complete print before executing the next instruction. like putting a delay before executing the next instruction.

Re: Security Flaw in Popular Disk Encryption Technologies
You might want to take a look at eNova (http://www.enovatech.net/) who are pointing at interesting hardware using their crypto technology. = the idea of closed-source hardware-based crypto disk drive may appeal to some, but i've seen too many similar things fail through stupidity, malice, etc. Compared to in-core keys which have to stay there while the device is mounted? Yeah. Great disadvantage. one probably wouldn't have to look hard for more examples of secure hardware that isn't secure. I guess you never did a formal evaluation of you security relevant subsystems anyway. there's just no way that hardware crypto can provide the peace of mind that open-source crypto does Let's put it that way: There is no open source solution that doesn't spill its beans too easily - key container and crypto engine should be brought together close enough to force complete destruction of the keys should anyone try to get access to them _or_ to the data path between them. Just take a look at Apple's last failure in this regard (the iPhone) and you'll see an example of not close enough. And no, I'm not talking about a mobile system, I'm more worried about the case of physical security not being strong enough (like in the case of governmental goons breaking down your doors or US customs and immigration staff seizing running machines [turn your machine on and prove to us that it isn't a bomb... Thank you, now it's ours.] as they have already done); emergency shutdown of all systems should reliably render your data inaccessible. The fact that British authorities lost four mobile computers with masses of sensitive data (like a complete list of their military reserve personnel including complete financial details) on their disks since October 2007 rather makes me laugh - they don't deserve crypto solutions but a good flogging with a bundle power cords. Anyway: I don't completely trust any system where keys have to travel across an unprotected bus. I'm still sad about TPMs not having made their way at least into 99% of the server mainboards. Just take a look at ISBN://978-0-7506-7960-2 (you just shouldn't completely hand over the device to your friendly OS vendor) and ISBN://0-387-23916-2 (which will prove your point - even IBM didn't follow the think before crypto rule). (or maybe my tin-foil hat is too tight). You got too close to Theo the Rat, that's all. I guess we should take this off (at least *this* list). And tell me if you want to read the books.

Re: synchronous freebsd print
This is a standard C question. Sorry, if this clarification is too simple, but I thought freeBSD kernel implemented its own print function. and the man for fflush says it is in the standard C-library. and the kernel source has no defn for fflush. I saw lots of kernel related questions asked in this list, so I posted my question here. Please correct me if I am wrong. and Yes in the kernel code I have a \n at the end of my print, still the print is not complete and the line next to it that causes the crash does not give the result I want. Is this a common scenario or am I doing something wrong. Sanjeev.

By default, read() will restart itself automatically, regardless
of whether the socket is blocking or not, as long as there is
data to be read in the socket receive buffer. You can change
this behavior by calling sigaction(). For example, the code
below will make SIGTERM interrupt system calls. They will return
an error code, usually -1, with the global errno set to EINTR.
If the socket is non-blocking and the socket receive buffer is
empty, then read() will also return an error, but with errno set
to EWOULDBLOCK.
#include signal.h
struct sigaction sigact;
sigact.sa_handler = sigterm_handler;
sigemptyset( sigact.sa_mask );
sigact.sa_flags = 0;
if ( sigaction( SIGTERM, sigact, NULL ) 0 )
{
perror( sigaction() );
exit( 1 );

I dont think you can rename tags using a single command. What you can do instead is create a new tag at the same point as the old tag, and then delete the old tag. eg - cvs rtag -r old-foo-1-2-3 new-foo-1-2-3 module_name cvs rtag -d old-foo-1-2-3 module_name Yes, I mentioned that above [*]. You can't do that with branch tags. You can use cvs admin -n or -N with branch tags. Anyway, I'm wondering if anyone has a script which iterates over existing tags and renames them to old_*. Maybe that will make it more clear what I'm looking for? ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

You don't really need a `script' to do this. Tags in CVS are not versioned, so you can force-tag the repo-copied files and move the tag to its new place. For example if you have two files: foo.c,v bar.c,v and bar.c,v is a repo-copy of foo.c,v then you move the tag only for the bar.c file by checking it out, and running: cvs tag -f -r 1.2 bar.c ^^^ you're missing the tag name in this example, but... This should force/move the tag to point revision 1.2. I don't want to move the tag... I want to invalidate old tags by renaming them to something else (like foo-1-2-3 - old_foo-1-2-3). Note that just using cvs to rename a tag (by tagging with the new name and then removing the former name) has issues when you try to do that with branch tags. Anyway, I'm pretty sure the FreeBSD cvs-meisters run something to invalidate tags after doing a repo copy. That's the information I was looking for.

Is it possible that modern wireless card only supports WPA and not WEP or this is a bug in the driver?
I have a Linksys PCI wireless card that is being attached by ral driver: ral0: Ralink Technology RT2561S mem 0xcffe8000-0xcffe irq 17 at device 10.0 on pci0 ral0: MAC/BBP RT2561C, RF RT2527 ral0: Ethernet address: 00:18:f8:2e:40:25 ral0: [ITHREAD] But when I do 'ifconfig ral0 list caps' it returns: ral0=2181e500IBSS,HOSTAP,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2,BGSCAN and WEP isn't there. This looks amazing since WEP is older and very widespread. So how can I tell if this card can't really support WEP or it's the driver that can't support it?

I see. I am sure anybody who doesn't know this will get confused and will have the same question. Isn't it better to have 2 separate flags in CAPS: for example WEP and WEPHW? WEP would mean that WEP is supported and WEPHW would mean that it's supported through hardware.

If you cannot use a feature you'll get an error when you try to use it. There simply are not enough capability bits around to waste on features that are always true. If I reorg this stuff (and I intend to to split crypto out into a separate features word because we are out of bits) then I can look into expanding the status. To be honest you're the first person that's even noticed you can list capabilities in the 3+ years that's been in place (or at least made public mention).

If I reorg this stuff (and I intend to to split crypto out into a separate features word because we are out of bits) then I can look into expanding the status. Exactly, I got errors while trying to use WEP with FreeBSD-based wireless access point. And I looked in four eyes at all options and capabilities. And I first thought that WEP support is a problem. Basically AP with WEP encryption doesn't work with this card. Now I wonder if this software-based WEP support can be responsible for this failure. To be honest you're the first person that's even noticed you can list capabilities in the 3+ years that's been in place (or at least made public mention). Hardly seems like something that's constantly confused people. Ok I will correct myself: this is very confusing to people who look and notice. Though there are not too many obviously. But caps are mentioned in the handbook. And it particularly says there: ifconfig /ath0/ list caps skip This output displays the card capabilities skip Various supported ciphers are also mentioned: WEP, TKIP, WPA2, etc., these informations are important to know what security protocols could be set on the Access Point. So from this one can conclude that WEP isn't supported. I guess it's good to mention here that WEP is always supported no matter what WEP flag says.
