kernel/tools/testing/selftests/bpf/test_progs.h, branch linux-5.2.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.2.y2019-04-03T23:27:38Zselftests/bpf: add few verifier scale tests2019-04-03T23:27:38ZAlexei Starovoitovast@kernel.org2019-04-02T04:27:48Zurn:sha1:e5e7a8f2d858a91b79c4afc51a3f15edcbf9cb60
Add 3 basic tests that stress verifier scalability.
test_verif_scale1.c calls non-inlined jhash() function 90 times on
different position in the packet.
This test simulates network packet parsing.
jhash function is ~140 instructions and main program is ~1200 insns.
test_verif_scale2.c force inlines jhash() function 90 times.
This program is ~15k instructions long.
test_verif_scale3.c calls non-inlined jhash() function 90 times on
But this time jhash has to process 32-bytes from the packet
instead of 14-bytes in tests 1 and 2.
jhash function is ~230 insns and main program is ~1200 insns.
$ test_progs -s
can be used to see verifier stats.

Add new prog_tests directory where tests are supposed to land.
Each prog_tests/<filename>.c is expected to have a global function
with signature 'void test_<filename>(void)'. Makefile automatically
generates prog_tests/tests.h file with entry for each prog_tests file:
#ifdef DECLARE
extern void test_<filename>(void);
...
#endif
#ifdef CALL
test_<filename>();
...
#endif
prog_tests/tests.h is included in test_progs.c in two places with
appropriate defines. This scheme allows us to move each function with
a separate patch without breaking anything.
Compared to the recent verifier split, each separate file here is
a compilation unit and test_progs.[ch] is now used as a place to put
some common routines that might be used by multiple tests.
