This series adds various misc improvements to BPF: detection of BPF helper definition misconfiguration for mem/size argument pairs, csum_diff helper also for XDP, various test cases, removal of the recently added pure_initcall(), restriction of the jit sysctls to cap_sys_admin for initns, a minor size improvement for x86 jit in alu ops, output of complexity limit to verifier log and last but not least having the event output more flexible with moving to const_size_or_zero type.
Thanks! Daniel Borkmann (9): bpf, verifier: detect misconfigured mem,size argument pair bpf: add csum_diff helper to xdp as well bpf: add couple of test cases for signed extended imms bpf: add couple of test cases for div/mod by zero bpf: get rid of pure_initcall dependency to enable jits bpf: restrict access to core bpf sysctls bpf, x86: small optimization in alu ops with imm bpf: add upper complexity limit to verifier log bpf: move event_output to const_size_or_zero for xdp/skb as well arch/arm/net/bpf_jit_32.c | 2 - arch/arm64/net/bpf_jit_comp.c | 2 - arch/mips/net/bpf_jit.c | 2 - arch/mips/net/ebpf_jit.c | 2 - arch/powerpc/net/bpf_jit_comp.c | 2 - arch/powerpc/net/bpf_jit_comp64.c | 2 - arch/s390/net/bpf_jit_comp.c | 2 - arch/sparc/net/bpf_jit_comp_32.c | 2 - arch/sparc/net/bpf_jit_comp_64.c | 2 - arch/x86/net/bpf_jit_comp.c | 37 ++++++++-- kernel/bpf/core.c | 19 +++-- kernel/bpf/verifier.c | 82 +++++++++++++++------- lib/test_bpf.c | 104 ++++++++++++++++++++++++++++ net/core/filter.c | 6 +- net/core/sysctl_net_core.c | 60 ++++++++++++++-- net/socket.c | 9 --- tools/testing/selftests/bpf/test_verifier.c | 87 +++++++++++++++++++++++ 17 files changed, 347 insertions(+), 75 deletions(-) -- 2.9.5
