selftests/bpf: add verifier cgroup storage tests
Add the following verifier tests to cover the cgroup storage
functionality:
1) valid access to the cgroup storage
2) invalid access: use regular hashmap instead of cgroup storage map
3) invalid access: use invalid map fd
4) invalid access: try access memory after the cgroup storage
5) invalid access: try access memory before the cgroup storage
6) invalid access: call get_local_storage() with non-zero flags
For tests 2)-6) check returned error strings.
Expected output:
$ ./test_verifier
#0/u add+sub+mul OK
#0/p add+sub+mul OK
#1/u DIV32 by 0, zero check 1 OK
...
#280/p valid cgroup storage access OK
#281/p invalid cgroup storage access 1 OK
#282/p invalid cgroup storage access 2 OK
#283/p invalid per-cgroup storage access 3 OK
#284/p invalid cgroup storage access 4 OK
#285/p invalid cgroup storage access 5 OK
...
#649/p pass modified ctx pointer to helper, 2 OK
#650/p pass modified ctx pointer to helper, 3 OK
Summary: 901 PASSED, 0 SKIPPED, 0 FAILED
