this might be old news already, but just in case...:
The 2.6.6-mm1 tree includes, among many other things, patches which add
two new /proc/sys variables. They are:
If this value is non-zero, it is interpreted as a group ID which
gives access to the the "huge pages" feature of the 2.6 VM.
This variable behaves similarly, but it controls access to the
mlock() system call (which locks memory into physical RAM) instead.
And continues with comments from Andrew:
The problem, it seems, is that there are no better solutions on the
horizon. Says Andrew Morton:
""Capabilities are broken and don't work. Nobody has a clue how to provide
the required services with SELinux and nobody has any code and we need the
feature *now* before vendors go shipping even more ghastly stuff. ""
This suggests that there is a good chance that realtime-lsm could be
accepted to the mainline kernel tree, if submitted!
Audio software for Linux!
