Extends test_loader.c:test_loader__run_subtests() by allowing to
execute BPF_PROG_TEST_RUN bpf command for selected programs.
This is similar to functionality provided by test_verifier.
Adds the following new attributes controlling test_loader behavior:
__retval(...)
__retval_unpriv(...)
* If any of these attributes is present, the annotated program would
be executed using libbpf's bpf_prog_test_run_opts() function.
* If __retval is present, the test run would be done for program
loaded in privileged mode.
* If __retval_unpriv is present, the test run would be done for
program loaded in unprivileged mode.
* To mimic test_verifier behavior, the actual run is initiated in
privileged mode.
* The value returned by a test run is compared against retval
parameter.
The retval attribute takes one of the following parameters:
- a decimal number
- a hexadecimal number (must start from '0x')
- any of a three special literals (provided for compatibility with
test_verifier):
- INT_MIN
- POINTER_VALUE
- TEST_DATA_LEN
An example of the attribute usage:
SEC("socket")
__description("return 42")
__success __success_unpriv __retval(42)
__naked void the_42_test(void)
{
asm volatile (" \
r0 = 42; \
exit; \
" ::: __clobber_all);
}
