Subject: [dpdk-dev] [PATCH v2 0/5] bpf: add support for BPF_ABS/BPF_IND instructions
Date: Wed, 27 May 2020 15:16:48 +0100 [thread overview]
Message-ID: <20200527141653.15576-1-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <20200518155245.11380-1-konstantin.ananyev@intel.com>
To fill the gap with linux kernel eBPF implementation,
add support for two non-generic instructions:
(BPF_ABS | <size> | BPF_LD) and (BPF_IND | <size> | BPF_LD)
which are used to access packet data in a safe manner.
Make necessary changes in BPF verifier, interpreter and x86 JIT code.
Konstantin Ananyev (5):
test/bpf: fix few small issues
bpf: fix add/sub min/max estimations
bpf: add support for packet data load instructions
test/bpf: add new test cases for mbuf load instructions
bpf: x86 JIT support for packet data load instructions
