This patch set adds a number of new tests to the test_bpf.ko test suite. It also corrects a faulty test case for tail call limits that failed erronously on the x86-64 and i386 JITs. The tests are intended to verify the correctness of eBPF JITs. Changes since v3: * New patch 13 to fix faulty test cases for tail call error paths (13/14). * Fixed new tail call limit test accordingly (14/14). Changes since v2: * Fixed tail call test case to handle the case where a called function is outside the 32-bit range of the BPF immediate field. Such calls are now omitted in this test. (13/14) * Fixed typo in commit message.
