Jeff Xu, I apologize for this churn: I was forced to drop your
Reviewed-by and Tested-by tags from 2 of the 3 mseal patches, because
the __NR_mseal fix is completely different now.
Changes since v1:
a) Reworked the mseal fix to use the kernel's in-tree unistd*.h files,
instead of hacking in a __NR_mseal definition directly. (Thanks to David
Hildenbrand for pointing out that this needed to be done.)
b) Fixed the subject line of the kvm and mdwe patch.
c) Reordered the patches so as to group the mseal changes together.
d) ADDED an additional patch, 6/6, to remove various __NR_xx items and
checks from the mm selftests.
Cover letter, updated for v2:
Eventually, once the build succeeds on a sufficiently old distro, the
idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then
after that, from selftests/lib.mk and all of the other selftest builds.
For now, this series merely achieves a clean build of selftests/mm on a
not-so-old distro: Ubuntu 23.04. In other words, after this series is
applied, it is possible to delete $(KHDR_INCLUDES) from
selftests/mm/Makefile and the build will still succeed.
1. Add tools/uapi/asm/unistd_[32|x32|64].h files, which include
definitions of __NR_mseal, and include them (indirectly) from the files
that use __NR_mseal. The new files are copied from ./usr/include/asm,
which is how we have agreed to do this sort of thing, see [1].
2. Add fs.h, similarly created: it was copied directly from a snapshot
of ./usr/include/linux/fs.h after running "make headers".
3. Add a few selected prctl.h values that the ksm and mdwe tests require.
4. Factor out some common code from mseal_test.c and seal_elf.c, into a
new mseal_helpers.h file.
5. Remove local __NR_* definitions and checks.
