Subject: [PATCH v2 net-next 0/3] seccomp filter JIT
Date: Fri, 26 Apr 2013 22:17:24 -0400 [thread overview]
Message-ID: <1367029047-14830-1-git-send-email-xi.wang@gmail.com> (raw)
The first patch refactors bpf_jit_compile()/bpf_jit_free() to provide
a unified interface for both packet and seccomp filters.
The next two patches implement JIT for seccomp filters on x86 and ARM,
respectively.
Thanks to Heiko Carstens for testing the build on s390 and Eric Dumazet
for the comments on x86 JIT.
Changes:
make better patch splitting
remove arch at jit time in x86
add more comments in x86
Xi Wang (3):
filter: refactor BPF JIT for seccomp filters
x86: bpf_jit_comp: support BPF_S_ANC_SECCOMP_LD_W instruction
ARM: net: bpf_jit_32: support BPF_S_ANC_SECCOMP_LD_W instruction
