Date: Mon, 31 Dec 2012 14:59:40 +0100 From: Daniel Borkmann <dborkman@...hat.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org Subject: [PATCH net-next 0/8] Add complementary BPF conditional jump instructions This set adds adds jump operations for lt (<), le (<=), ne (!=) that compare A with K resp. X in order to facilitate filter programming with conditional jumps, as also available in McCanne et. al's BPF+ paper (``BPF+: Exploiting Global Data-flow Optimization in a Generalized Packet Filter Architecture''). Also, follow-up BPF JIT implementations for x86, Sparc and PowerPC are added in this set.
