The netperf benchmark shows a 5.73% reduction in throughput for
small (64 byte) transfers by unconfined tasks.
DEFINE_AUDIT_SK() in aa_label_sk_perm() should not be performed
unconditionally, rather only when the label is confined.

This is a follow up message to the original "Abysmal Receive Performance"

Well, after poking around, I eventually narrowed the problem down to the
fact that the system BIOS did not enable PCI->RAM write posting. After I
enabled that

The computer in question is a dual Pentium 90 machine. The machine has

I'm working on a problem on alpha SMP on the
