These are not the error message, just show the fd flags. The error is it should return -22 (-EINVAL) for this test case, but it returns 3 which indicates a successful openat2() calling. >>> not ok 102 openat2 with incompatible flags (O_PATH | O_LARGEFILE) >>> fails with -22 (Invalid argument) >>> >>>> >>>> Signed-off-by: Baolin Wang <baolin.wang@linux.alibaba.com> >> >> Could you apply this patch if no objection from your side?

The issue is that O_LARGEFILE is set to 0 by glibc because glibc appears to hide the nuts and bolts of largefile support from userspace. I couldn't find a nice way of doing a architecture-dependent includes of include/uapi from kselftests, so I just went with this instead -- but I agree that a proper include would be better if someone can figure out how to do it. > Christian, Aleksa, > > Can you review this patch and let me know if this approach looks right. Reviewed-by: Aleksa Sarai <cyphar@cyphar.com> It'd be nice to fix this for the other architectures I mention in the comment (mips, parisc, powerpc, sparc) -- which are the ones that I could find that had a custom O_LARGEFILE definition. > > > > --- > > > > tools/testing/selftests/openat2/openat2_test.c | 4 ++++ > > > > 1 file changed, 4 insertions(+) > > > > > > > > diff --git a/tools/testing/selftests/openat2/openat2_test.c b/tools/testing/selftests/openat2/openat2_test.c > > > > index d7ec1e7..1bddbe9 100644 > > > > --- a/tools/testing/selftests/openat2/openat2_test.c > > > > +++ b/tools/testing/selftests/openat2/openat2_test.c > > > > @@ -22,7 +22,11 @@ > > > > * XXX: This is wrong on {mips, parisc, powerpc, sparc}. > > > > */ > > > > #undef O_LARGEFILE > > > > +#ifdef __aarch64__ > > > > +#define O_LARGEFILE 0x20000 > > > > +#else > > > > #define O_LARGEFILE 0x8000 > > > > +#endif > > > > struct open_how_ext { > > > > struct open_how inner; > > > > > > > > thanks, > -- Shuah -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/> [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 228 bytes --] ^ permalink raw reply [flat|nested] 10+ messages in thread
