[linux-audio-dev] LSM: Linux 2.6 Kernel Capability LSM Module Local Privilege Elevation

by Frank Barknecht

Hi, careful with the linux security module: As reported on Bugtraq, there's a vulnerability when loading LSM as a module instead of compiling it into the kernel: "When POSIX Capability LSM module isn't compiled into kernel, after inserting Capability module into kernel, all existed normal users processes will have total Capability privileges of superuser (root)." Read on here: http://www.derkeiler.com/Mailing-Lists/securityfocus/bugtraq/2004-12/0390.h… Ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-dev] GUS Patch Documentation

by Stefan Westerfeld

Hi! Is there somewhere useful documentation explaining how GUS Patches should sound? I am currently implementing support for GUS Patches for BEAST, and the documentation from wotsit.org for instance only explains that there ways to specify envelopes, tremolo and vibrato in GUS Patches, but not how the values specified there actually should sound (i.e. whats the meaning of a tremolo sweep value of 25?). The only method for getting this right I've come up with so far is trying to understand the timidity code... Cu...

[linux-audio-dev] 2.6.10-rc2-mm3 Hang

by Spencer Russell

It would seem that perhaps my hangup problems in 2.6 aren't necessarily related to my US428. I got the 2.6.10-rc2 sources, and applied the mm3, rt2(Realtime LSM), Ingo's realtime-preempt, and usx2y 0.8.7.1 patches. The kernel patched and compiled fine, but it hangs after several minutes of normal web usage. I could still ssh into it(after a while that stopped working, too), and top showed several IRQ # processes running, which is abnormal. I'm not sure what else to look for, or what this means, exactly. Any ideas? should I be posting this to a different list? Thanks a lot, spencer

Re: [linux-audio-dev] Re: rosegarden, alsa_seq and usx2y

by Stefan Turner

Thanks Fons and Rui for replies, sorry this is so late, been off the net. The extra flags worked ok, but there's still problems which I guess are due to CCRMA using jack-audio-connection-kit instead of jack... but I can wait till the new usx2y is in alsa proper. (Thanks to all involved for this!) Out of interest, does anyone know how the performance compares to using the supplied drivers in Windows?

I bastardized the jackd-us2xy rpm to make a nice deb file, but jackd still says "unknown driver 'usx2y'".

[linux-audio-dev] SWH 0.4.12 and SC4 Mono

by Doug McLain

I was happy as all get out to find that swh 0.4.12 has a mono version of my favorite compressor, SC4. Unfortunately, ardour fails to load it with an unresolved symbol 'db-data'. It seems this plugin wasn't being statically linked to libdb.a during build, like the others. I did the following changes to the Makefile *after* ./configure, and all is well. Autotools are a complete mystery to me, so I have no idea what the corrrect fix is, but this works for now untill the release is corrected. SC4 Mono was a great suprise xmas present for me, thanks Steve n friends, and Happy Holidays!

[linux-audio-dev] Tascam US428 Continued hangups

by Spencer Russell

Sorry to cross-post, but i didn't get any response on LAU, and was hoping maybe there're some developers that might have a better idea of what's going on. A while ago I was having trouble with my US428 hanging my system, usually directly after I tried to start JACK. Then lots of school-type stuff came up, and I set it aside for a while, and just used the built-in soundcard. Now that finals are over, I'm looking at tryint to get it to work again. So I downloaded the 2.6.10-rc2 source, applied the mm3, usx2y-0.8.7, and rt2 patches, used make-kpkg to make a nice debian-friendly package, and installed the kernel and modules. I also got the realtime-lsm module, and the package that has the scripts to set it up all nice and easy. So I boot it up, and aside from my touchpad not working, everything looks good. So I tail -f /var/log/messages, and plug in my US428. It seems to load the firmware and start us428control the way it's supposed to, and I can even start jack and run the xmms-jack out plugin and listen to music through it. Seems to work great. But as soon as I start ardour, I get this: kernel: Sequence Error!(hcd_frame=1152ep=10out;wait=120,frame=124). kernel: Most propably some urb of usb-frame 120 is still missing. kernel: Cause could be too long delays in usb-hcd interrupt handling. and qjackctl up and disapears, and ardour gives an error about being booted by jack. but I'm pretty stoked at at least my computer didn't hang(as it used to), until I unplug the device, and do some other stuff, and then it hangs. So I guess I'm in a slightly better position than before, but I'm getting pretty close to selling this, and saving up for one of the RME pcmcia interfaces. thanks for any ideas, -spencer

I wonder why Simulink don't do that. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software
