Subject: Re: [LTP] [PATCH] Added test for mmap() with MAP_SHARED_VALIDATE.
Date: Tue, 4 Apr 2023 13:07:51 +0200 [thread overview]
Message-ID: <20230404110751.GA1268429@pevik> (raw)
In-Reply-To: <20230328103951.GA755576@pevik>
Hi all,
FYI test fails on ppc64le: mmap() with MAP_SHARED_VALIDATE | (1 << 7) is
supposed to fail with EOPNOTSUPP, but on ppc64le it fails with EFAULT.
Obviously (1 << 7) being expected as invalid flag is not working well at least
on ppc64le. It might be something page size related or alignment. I was looking
into SYSCALL_DEFINE6(mmap, ...) implementations. Although ppc64le implementation
is not the same as most of implementations on other archs, in the end it also
calls ksys_mmap_pgoff(addr, len, prot, flags, fd, off >> shift) as the other
archs. Any idea what could be a problem?
Kind regards,
Petr
