Pulseaudio breaks with sysfs/debugfs restrictions + PaX Flag

Postby GBit » Fri Dec 14, 2012 4:17 am

So on Ubuntu 12.10 Pulseaudio runs but sound doesn't seem to work when sysfs/debugfs restrictions are enabled. Any way around this or is it just Pulseaudio's fault?

Another question about the behavior of pax flags. If I disable soft mode the entire system runs with PaX. But, is it possible to run the entire system with PaX and then still use paxctl/flags to disable features on a per-program basis?

CONFIG_GRKERNSEC_SYSFS_RESTRICT is not recommended for desktop environments -- it is only automatically enabled via a "server" configuration setting.

that's what paxctl/setfattr/RBAC are for ;).
