[opensuse-kernel] enable some hardening options?
by Marcus Meissner 02 Jul '13

02 Jul '13

Hi, Could you please enable some of the "newer" kernel hardening options: CONFIG_STRICT_DEVMEM CONFIG_PROC_KCORE CONFIG_SECURITY_DMESG_RESTRICT to restrict attack surfaces / kernel address leakage.

[opensuse-kernel] Music production - Low latency or real time kernel?
by Stephan Barth 02 Jul '13

02 Jul '13

Hi, I have read several comments about the necessity of a real time kernel for music creation and production. However, others say low latency should be sufficient and our kernel is supposed to provide "lower latency", but this doesn't satisfy all applications. So what would be the right kernel, settings or compile time options for making music on openSUSE?

Hi Jeff, > Dirk, I've been modifying the summary lines of your patches to be more > patches.arch/cubox-configuration.patch: Adjust > > isn't very useful when reading the commit log, so I replaced it with: > arm: cubox, use timer initialization directly in the machine descriptor Sounds good to me. Thanks for the feedback, I'll keep an eye on this in the future. Thanks!
