This patch adds '--timing' to test_progs. It tracks and print timing information for each tests, it also prints top 10 slowest tests in the summary.

In this patch - 1) Add a new prog "for_each_helper" which tests the basic functionality of the bpf_for_each helper. 2) Add pyperf600_foreach and strobemeta_foreach to test the performance of using bpf_for_each instead of a for loop The results of pyperf600 and strobemeta are as follows: ~strobemeta~ Baseline verification time 6808200 usec stack depth 496 processed 592132 insns (limit 1000000) max_states_per_insn 14 total_states 16018 peak_states 13684 mark_read 3132 #188 verif_scale_strobemeta:OK (unrolled loop) Using bpf_for_each verification time 31589 usec stack depth 96+408 processed 1630 insns (limit 1000000) max_states_per_insn 4 total_states 107 peak_states 107 mark_read 60 #189 verif_scale_strobemeta_foreach:OK ~pyperf600~ Baseline verification time 29702486 usec stack depth 368 processed 626838 insns (limit 1000000) max_states_per_insn 7 total_states 30368 peak_states 30279 mark_read 748 #182 verif_scale_pyperf600:OK (unrolled loop) Using bpf_for_each verification time 148488 usec stack depth 320+40 processed 10518 insns (limit 1000000) max_states_per_insn 10 total_states 705 peak_states 517 mark_read 38 #183 verif_scale_pyperf600_foreach:OK Using the bpf_for_each helper led to approximately a 100% decrease in the verification time and in the number of instructions.

This patch tests bpf_loop in pyperf and strobemeta, and measures the verifier performance of replacing the traditional for loop with bpf_loop. The results are as follows: ~strobemeta~ Baseline verification time 6808200 usec stack depth 496 processed 554252 insns (limit 1000000) max_states_per_insn 16 total_states 15878 peak_states 13489 mark_read 3110 #192 verif_scale_strobemeta:OK (unrolled loop) Using bpf_loop verification time 31589 usec stack depth 96+400 processed 1513 insns (limit 1000000) max_states_per_insn 2 total_states 106 peak_states 106 mark_read 60 #193 verif_scale_strobemeta_bpf_loop:OK ~pyperf600~ Baseline verification time 29702486 usec stack depth 368 processed 626838 insns (limit 1000000) max_states_per_insn 7 total_states 30368 peak_states 30279 mark_read 748 #182 verif_scale_pyperf600:OK (unrolled loop) Using bpf_loop verification time 148488 usec stack depth 320+40 processed 10518 insns (limit 1000000) max_states_per_insn 10 total_states 705 peak_states 517 mark_read 38 #183 verif_scale_pyperf600_bpf_loop:OK Using the bpf_loop helper led to approximately a 99% decrease in the verification time and in the number of instructions.

Add a big batch of selftest to extend test_progs with various tc link, attach ops and old-style tc BPF attachments via libbpf APIs. Also test multi-program attachments including mixing the various attach options: # ./test_progs -t tc_link #179 tc_link_base:OK #180 tc_link_detach:OK #181 tc_link_mix:OK #182 tc_link_opts:OK #183 tc_link_run_base:OK #184 tc_link_run_chain:OK Summary: 6/0 PASSED, 0 SKIPPED, 0 FAILED All new and existing test cases pass.

Attemting to do sock_lock on .recvmsg may cause a deadlock as shown bellow, so instead of using sock_sock this uses sk_receive_queue.lock on bt_sock_ioctl to avoid the UAF: INFO: task kworker/u9:1:121 blocked for more than 30 seconds.
