From 341b3e7b7b89315c43d262da3199098bcf9bbe57 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Fri, 9 Nov 2018 13:03:26 +0000 Subject: bpf: call verify_insn from its callback in struct bpf_offload_dev We intend to remove the dev_ops in struct bpf_prog_offload, and to only keep the ops in struct bpf_offload_dev instead, which is accessible from more locations for passing function pointers. But dev_ops is used for calling the verify_insn hook. Switch to the newly added ops in struct bpf_prog_offload instead. To avoid table lookups for each eBPF instruction to verify, we remember the offdev attached to a netdev and modify bpf_offload_find_netdev() to avoid performing more than once a lookup for a given offload object.
