This patchset brings JIT support to seccomp filters for x86_64 and ARM. It is against the net-next tree.
The current BPF JIT interface only accepts sk_filter, not seccomp_filter. Patch 1/6 refactors the interface to make it more general. With the refactored interface, patches 2/6 and 3/6 implement the seccomp BPF_S_ANC_SECCOMP_LD_W instruction in x86 & ARM JIT. Status: * x86_64 & ARM: JIT tested with seccomp examples. * powerpc [4/6]: no seccomp change - compile checked. * sparc [5/6] & s390 [6/6]: no seccomp change - untested. Sorry I have no sparc or s390 build environment here. Can someone help check 5/6 and 6/6? Thanks.
