Subject: [PATCH v2 0/6] cleanups, fixes, and progress towards avoiding "make headers"

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.

header files")

Subject: [PATCH v2 2/6] selftests/mm: mseal, self_elf: factor out test macros and other duplicated items

Clean up and move some copy-pasted items into a new mseal_helpers.h.

1. The test macros can be made safer and simpler, by observing that they
are invariably called when about to return. This means that the macros
do not need an intrusive label to goto; they can simply return.

2. PKEY* items. We cannot, unfortunately use pkey-helpers.h. The best we
can do is to factor out these few items into mseal_helpers.h.

3. These tests still need their own definition of u64, so also move that
to the header file.

Subject: [PATCH v2 3/6] selftests/mm: mseal, self_elf: rename TEST_END_CHECK to REPORT_TEST_PASS

Now that the test macros are factored out into their final location, and
simplified, it's time to rename TEST_END_CHECK to something that
represents its new functionality: REPORT_TEST_PASS.

Subject: [PATCH v2 4/6] selftests/mm: fix vm_util.c build failures: add snapshot of fs.h

On Ubuntu 23.04, on a clean git tree, the selftests/mm build fails due
10 or 20 missing items, all of which are found in fs.h, which is created
via "make headers". However, as per [1], the idea is to stop requiring
"make headers", and instead, take a snapshot of the files and check them
in.

Here are a few of the build errors:

vm_util.c:34:21: error: variable has incomplete type 'struct pm_scan_arg'
struct pm_scan_arg arg;
...
vm_util.c:45:28: error: use of undeclared identifier 'PAGE_IS_WPALLOWED'
...
vm_util.c:55:21: error: variable has incomplete type 'struct page_region'
...
vm_util.c:105:20: error: use of undeclared identifier 'PAGE_IS_SOFT_DIRTY'

To fix this, add fs.h, taken from a snapshot of ./usr/include/linux/fs.h
after running "make headers".

header files")

Subject: [PATCH v2 1/6] selftests/mm: mseal, self_elf: fix missing __NR_mseal

The selftests/mm build isn't exactly "broken", according to the current
documentation, which still claims that one must run "make headers",
before building the kselftests. However, according to the new plan to
get rid of that requirement [1], they are future-broken: attempting to
build selftests/mm *without* first running "make headers" will fail due
to not finding __NR_mseal.

Therefore, add ./usr/include/asm/unistd_[32|x32|64].h (created via
"make headers") to tools/uapi/, and change the selftests/mm files that
require __NR_mseal to include from the correct location. The way to do
so is to include <linux/unistd.h> instead of just <unistd.h>.

[1] commit e076eaca5906 ("selftests: break the dependency upon local
header files")

Subject: [PATCH v2 5/6] selftests/mm: kvm, mdwe fixes to avoid requiring "make headers"

On Ubuntu 23.04, the kvm and mdwe selftests/mm build fails due to
missing a few items that are found in prctl.h. Here is an excerpt of the
build failures:

ksm_tests.c:252:13: error: use of undeclared identifier 'PR_SET_MEMORY_MERGE'
...
mdwe_test.c:26:18: error: use of undeclared identifier 'PR_SET_MDWE'
mdwe_test.c:38:18: error: use of undeclared identifier 'PR_GET_MDWE'

Fix these errors by adding the missing items to vm_util.h, and include
vm_util.h from mdwe_test.c.

Subject: [PATCH v2 6/6] selftests/mm: remove local __NR_* definitions

This continues the work on getting the selftests to build without
requiring people to first run "make headers" [1].

Now that the system call numbers are in the correct, checked-in
locations in the kernel tree (./tools/include/uapi/asm/unistd*.h),
make sure that the mm selftests include that file (indirectly).

Doing so provides guaranteed definitions at build time, so remove all of
the checks for "ifdef __NR_xxx" in the mm selftests, because they will
always be true (defined).

[1] commit e076eaca5906 ("selftests: break the dependency upon local
header files")

What's the reason we don't target "linux/prctl.h" here? :)

... thinking again, are some of these headers arch-specific (IOW,
generating them per-arch would result in something slightly different)?

In tools/include/uapi/asm-generic/unistd.h, we already do have
__NR_mseal ...

Oh wow, yes they are. I'm guilty of x86-centric thinking (again).

hmm, this is going to make it really a lot of trouble to do this
approach. But there's no point in turning back now, so I guess I'd
better fire up the cross-compilers and generate for all the arches.

Yes, but it doesn't get used in selftests/mm, with the way headers are
set up right now.

Very good point. This is the Old Way of fixing these up, and I overlooked
that even though I'm busy adding the New Way. :)

I'll change this to use a new tools/include/uapi/linux/prctl.h and post
a v3, thanks for pointing this out.
