From: Abhishek Dubey <[email protected]> The first 2 patch enable support for instruction array. Now, the instruction offset map maintain the mapping: original inst -> xlated inst -> jited inst
The last two patch enable support for indirect jump. Any eligile register can store jump target address for control flow to jump. The features will be enabled on ppc32 in a separate series. All selftest related to instruction array and indirect jump are passing. ./test_progs-cpuv4 -n 20 #21/1?????? bpf_insn_array/one2one:OK #21/2?????? bpf_insn_array/simple:OK #21/3?????? bpf_insn_array/deletions:OK #21/4?????? bpf_insn_array/deletions-with-functions:OK #21/5?????? bpf_insn_array/blindness:OK #21/6?????? bpf_insn_array/incorrect-index:OK #21/7?????? bpf_insn_array/load-unfrozen-map:OK #21/8?????? bpf_insn_array/no-map-reuse:OK #21/9?????? bpf_insn_array/bpf-side-ops:OK #21?????????? bpf_insn_array:OK Summary: 1/9 PASSED, 0 SKIPPED, 0 FAILED ./test_progs-cpuv4 -n 21 #20/1?????? bpf_gotox/one-switch:OK #20/2?????? bpf_gotox/one-switch-non-zero-sec-offset:OK #20/3?????? bpf_gotox/two-switches:OK #20/4?????? bpf_gotox/big-jump-table:OK #20/5?????? bpf_gotox/static-global:OK #20/6?????? bpf_gotox/nonstatic-global:OK #20/7?????? bpf_gotox/other-sec:OK #20/8?????? bpf_gotox/static-global-other-sec:OK #20/9?????? bpf_gotox/nonstatic-global-other-sec:OK #20/10???? bpf_gotox/one-jump-two-maps:OK #20/11???? bpf_gotox/one-map-two-jumps:OK #20?????????? bpf_gotox:OK Summary: 1/11 PASSED, 0 SKIPPED, 0 FAILED Abhishek Dubey (4): powerpc64/bpf: Add support for instruction array selftest/bpf: Enable instruction array test for powerpc64 powerpc64/bpf: Add support for indirect jump selftest/bpf: Enable gotox tests for powerpc64 arch/powerpc/net/bpf_jit_comp.c | 6 ++++++ arch/powerpc/net/bpf_jit_comp64.c | 8 ++++++++ tools/testing/selftests/bpf/prog_tests/bpf_insn_array.c | 2 +- tools/testing/selftests/bpf/progs/verifier_gotox.c | 2 +- 4 files changed, 16 insertions(+), 2 deletions(-) -- 2.52.0
