This series follows up mostly with with some minor cleanups on top of 'Move ld_abs/ld_ind to native BPF' as well as implements better 32/64 bit immediate load into register and saves tail call init on cBPF for the arm64 JIT. Last but not least we add a couple of test cases. For details please see individual patches. Thanks!
v1 -> v2: - Minor fix in i64_i16_blocks() to remove 24 shift. - Added last two patches. - Added Acks from prior round. Daniel Borkmann (8): bpf, mips: remove unused function bpf, sparc: remove unused variable bpf, x64: clean up retpoline emission slightly bpf, arm32: save 4 bytes of unneeded stack space bpf, arm64: save 4 bytes of unneeded stack space bpf, arm64: optimize 32/64 immediate emission bpf, arm64: save 4 bytes in prologue when ebpf insns came from cbpf bpf: add ld64 imm test cases arch/arm/net/bpf_jit_32.c | 13 +--- arch/arm64/net/bpf_jit_comp.c | 115 +++++++++++++++++----------- arch/mips/net/ebpf_jit.c | 26 ------- arch/sparc/net/bpf_jit_comp_64.c | 1 - arch/x86/include/asm/nospec-branch.h | 29 ++++--- tools/testing/selftests/bpf/bpf_rand.h | 80 +++++++++++++++++++ tools/testing/selftests/bpf/test_verifier.c | 62 +++++++++++++++ 7 files changed, 228 insertions(+), 98 deletions(-) create mode 100644 tools/testing/selftests/bpf/bpf_rand.h -- 2.9.5
