[bpf-next, v4 0/5] Introduce eBPF flow dissector

2018-09-14 Thread Petar Penkov
From: Petar Penkov This patch series hardens the RX stack by allowing flow dissection in BPF, as previously discussed [1]. Because of the rigorous checks of the BPF verifier, this provides significant security guarantees. In particular, the BPF flow dissector cannot get inside of an infinite loop
