mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm

mmotm 2020-05-15-16-29 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-15-16-29 has been uploaded to

   http://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm

The above patch should have

#define __NR_process_madvise 443

not 442, in arch/arm64/include/asm/unistd32.h

and

 442    common  fsinfo                          sys_fsinfo
+443    common  process_madvise                 sys_process_madvise

The above patch should have

The above patch should have

#define __NR_process_madvise 443

not 442 in arch/arm64/include/asm/unistd32.h

mmotm 2020-05-19-21-47 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-19-21-47 has been uploaded to

   http://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm



This mmotm tree contains the following patches against 5.7-rc6:

mmotm 2020-05-21-20-42 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-21-20-42 has been uploaded to

   http://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

mmotm 2020-05-22-20-35 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-22-20-35 has been uploaded to

   http://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm

Randy,

I wasn't able to recreate this one.  If you can still do so, can you
share the .o file?

Actually, never mind... user error :-)  Will take a look.

Urgh, that's horrible code. That's got plain stac()/clac() calls on
instead of the regular uaccess APIs.

Anybody any clue about what the best way forward here is?

Also, I wonder how we get at memset() with AC set,..

Does it?  If this is from the code in linux-next, then the code does a
user_access_begin/end in csum_and_copy_{from,to}_user, then uses
unsafe_{get,put}_user inside those function itself.  But then they call
csum_partial_copy_generic with the __user casted away, but without any
comment on why this is safe.

Bah, clearly I was looking at the wrong tree. You're right, Al cleaned
it all up.

Let me try and figure out why objtool is unhappy with it.

*groan*, this is one of those CONFIG_PROFILE_ALL_BRANCHES builds. If I
disable that it goes away.

Still trying to untangle the mess it generated, but on first go it
looks like objtool is right, but I'm not sure what went wrong.

The problem is with the +0x113 branch, which is at 0x1d1.

That looks to be:

	if (!likely(user_access_begin(src, len)))
		goto out_err;

Except that the brach profiling stuff confused GCC enough to leak STAC
into the error path or something.

Reproduces for me with gcc-9 and gcc-10.

It looks to me like GCC is doing the right thing.  That likely()
translates to:

#  define likely(x)	(__branch_check__(x, 1, __builtin_constant_p(x)))

which becomes:

#define __branch_check__(x, expect, is_constant) ({			\
			long ______r;					\
			static struct ftrace_likely_data		\
				__aligned(4)				\
				__section(_ftrace_annotated_branch)	\
				______f = {				\
				.data.func = __func__,			\
				.data.file = __FILE__,			\
				.data.line = __LINE__,			\
			};						\
			______r = __builtin_expect(!!(x), expect);	\
			ftrace_likely_update(&______f, ______r,		\
					     expect, is_constant);	\
			______r;					\
		})

Here 'x' is the call to user_access_begin().  It evaluates 'x' -- and
thus calls user_access_begin() -- before the call to
ftrace_likely_update().

So it's working as designed, right?  The likely() just needs to be
changed to likely_notrace().

But if !x (ie we fail user_access_begin()), we should not pass STAC() on
the way to out_err. OTOH if x, we should not be jumping to out_err.

I'm most confused... must not stare at asm for a while.

Yeah, I saw that call to ftrace_likely_update() and got distracted.  I
forgot it's on the uaccess safe list.

From staring at the asm I think the generated code is correct, it's just
that the nested likelys with ftrace profiling cause GCC to converge the
error/success paths.  But objtool doesn't do register value tracking so
it's not smart enough to know that it's safe.

The nested likelys seem like overkill anyway -- user_access_begin() is
__always_inline and it already has unlikely(), which should be
propagated.

So just remove the outer likelys?

That fixes it. Ack!

[PATCH] x86/uaccess: Remove redundant likely/unlikely annotations

If there are no objections to the patch, I can add it to my objtool-core
branch unless anybody else wants to take it.  It only affects
linux-next.

From: Josh Poimboeuf <jpoimboe@redhat.com>
Subject: [PATCH] x86/uaccess: Remove redundant likely/unlikely annotations

Since user_access_begin() already has an unlikely() annotation for its
access_ok() check, "if (likely(user_access_begin))" results in nested
likely annotations.  When combined with CONFIG_TRACE_BRANCH_PROFILING,
GCC converges the error/success paths of the nested ifs, using a
register value to distinguish between them.

While the code is technically uaccess safe, it complicates the
branch-profiling generated code.  It also confuses objtool, because it
doesn't do register value tracking, resulting in the following warnings:

  arch/x86/lib/csum-wrappers_64.o: warning: objtool: csum_and_copy_from_user()+0x2a4: call to memset() with UACCESS enabled
  arch/x86/lib/csum-wrappers_64.o: warning: objtool: csum_and_copy_to_user()+0x243: return with UACCESS enabled

The outer likely annotations aren't actually needed anyway, since the
compiler propagates the error path coldness when it inlines
user_access_begin().

I'm surprised that gcc doesn't end up doing the obvious CSE and then
branch following and folding it all away in the end, but your patch is
obviously the right thing to do regardless, so ack on that.

Al - I think this had best go into your uaccess cleanup branch with
that csum-wrapper update, to avoid any unnecessary conflicts or
dependencies.

Sure, just let me verify that other branches don't introduce anything
of that sort...

... they don't.

OK, folded, rebuild #for-next, pushed both out...
