* selftests/bpf: fix sendmsg6_prog on s390Ilya Leoshkevich2019-07-221-2/+1
| | | | | | | | | | | | | | "sendmsg6: rewrite IP & port (C)" fails on s390, because the code in sendmsg_v6_prog() assumes that (ctx->user_ip6[0] & 0xFFFF) refers to leading IPv6 address digits, which is not the case on big-endian machines. Since checking bitwise operations doesn't seem to be the point of the test, replace two short comparisons with a single int comparison.

There is just slight difference between test_progs/test_maps and test_verifier. test_verifier's verifier/*.c files are not really compilable C files (they are more of include headers), so they can't be specified as explicit dependencies of test_verifier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When directories are used as prerequisites in Makefiles, they can cause a lot of unnecessary rebuilds, because a directory is considered changed whenever a file in this directory is added, removed or modified. If the only thing a target is interested in is the existence of the directory it depends on, which is the case for selftests/bpf, this directory should be specified as an order-only prerequisite: it would still be created in case it does not exist, but it would not trigger a rebuild of a target in case it's considered changed.

| * selftests/bpf: make PT_REGS_* work in userspaceIlya Leoshkevich2019-07-121-20/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, on certain architectures, these macros are usable only with kernel headers. This patch makes it possible to use them with userspace headers and, as a consequence, not only in BPF samples, but also in BPF selftests. On s390, provide the forward declaration of struct pt_regs and cast it to user_pt_regs in PT_REGS_* macros. This is necessary, because instead of the full struct pt_regs, s390 exposes only its first member user_pt_regs to userspace, and bpf_helpers.h is used with both userspace (in selftests) and kernel (in samples) headers. It was added in commit 466698e654e8 ("s390/bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type"). Ditto on arm64. On x86, provide userspace versions of PT_REGS_* macros. Unlike s390 and arm64, x86 provides struct pt_regs to both userspace and kernel, however, with different member names.

| * selftests/bpf: do not ignore clang failuresIlya Leoshkevich2019-07-121-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compiling an eBPF prog fails, make still returns 0, because failing clang command's output is piped to llc and therefore its exit status is ignored. When clang fails, pipe the string "clang failed" to llc. This will make llc fail with an informative error message. This solution was chosen over using pipefail, having separate targets or getting rid of llc invocation due to its simplicity. In addition, pull Kbuild.include in order to get .DELETE_ON_ERROR target, which would cause partial .o files to be removed.

Revert to using a ".word" to express the signature as data instead. The choice of signature is a valid trap instruction on arm32 little endian, where both code and data are little endian. ARMv6+ big endian (BE8) generates mixed endianness code vs data: little-endian code and big-endian data. The data value of the signature needs to have its byte order reversed to generate the trap instruction. Prior to ARMv6, -mbig-endian generates big-endian code and data (which match), so the endianness of the data representation of the signature should not be reversed. However, the choice between BE32 and BE8 is done by the linker, so we cannot know whether code and data endianness will be mixed before the linker is invoked. So rather than try to play tricks with the linker, the rseq signature is simply data (not a trap instruction) prior to ARMv6 on big endian. This is why the signature is expressed as data (.word) rather than as instruction (.inst) in assembler. Because a ".word" is used to emit the signature, it will be interpreted as a literal pool by a disassembler, not as an actual instruction. Considering that the signature is not meant to be executed except in scenarios where the program execution is completely bogus, this should not be an issue.

I also replaced the conditional ($(srctree),.) because the next commit will allow an absolute path to be used for $(srctree) even when building in the source tree.
