[PATCH 0/6] linux-yocto: consolidated pull request (5.0 kernel intro)

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Hi all,

The -rc8 of the kernel pushed this out a week longer than I would
have liked, but luckily the -dev kernel has been running 5.0 for
quite a while, so most of the issues had been worked out already.

In this series we have the bump of the libc-headers to 5.0, I've
built all arches for both musl and glibc, with no issues popping
up due to the headers bump. A few patches were dropped, since they
are now upstream.

I've also introduce the 5.0 versioned recipe in this series and
adjusted the two machines that still have a preferred version to
use it. Again, this was built and booted on all arches and over
several image types (minimal, sato, kernel-dev).

As usual lttng was tweaked to work with 5.0, but I was able to
keep it on the same 2.10 stable branch and only pull in a few
pending patches that haven't been formally released yet.

Once we get the h/w reference boards, and reference distros moved
to 4.19 and 5.0, I'll send a follow up patch to remove 4.18
from master.

I'll send follow up patches to the yocto-bsps and poky as
appropriate, but until the last few issues are resolved, they can
stay out of tree.

I captured as many details as possible in the commit messages of
the individual patches.

Cheers,

Bruce

[PATCH 1/6] kernel-yocto: allow kernel-meta repositories to be patched

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

For testing purposes, it is often easier to patch a fragment
in a kernel-meta repository versus needing to make a copy or
modify the source repository.

We can allow this sort of patching when a patchdir of kernel-meta
is passed (to indicate the nested kernel-meta repository).

Also note that we must patch the meta data before they are
processed/gathered, since migrated copies to the kernel source
directory will be used later.

Did you mean 'if subdir:' here?

I'm seeing duplicate attempts to apply a patch listed on SRC_URI in the 
linux-raspberrypi_4.14.bb recipe from meta-raspberrypi. The first 
attempt is in do_kernel_metadata and this succeeds, the second is in 
do_patch and this fails as the patch has already been applied.

In this case, patchdir = '' as there is no patchdir set for this in the 
recipe. The patch is still picked up when find_patches() is called with 
subdir='kernel-meta' since the test here is false and the comparison 
below is not performed.

Nope. I did mean if patchdir: here, that doesn't mean it is working perfectly,
but I did definitely mean patchdir.

Hmm. The only thing that should be patchable in the meta data
gathering is the meta data. Not the kernel source tree. It is just
there as a rough debug / devel trigger. kernel-meta is a separate
repo, so patches are only applied there.

Something that triggers in do_patch can't be patching that same
repo, since the kernel tree is separate ..

Is the raspberrypi recipe using the upstream kernel-cache repo
or is it doing something else ?

Is it also using patches with patchdir specified in the src_uri ?
If it isn't, I can't see how any of this is triggering.

I'm out of the office this week, but this is something I can sort
out .. can you send me the exact set of layers (and any
local.conf I'd need) to trigger this ? I'll have some time tomorrow
night to poke at it a bit.

I just did a build with meta-raspberrypi and did recreate the issue,
I'll have a look at see what I can do. I'll need to test some other
use cases against any changes I make, so it'll be a bit touchy :P

On a closer look, yes, it is safer to just have the test on subdir versus
some other compound conditions that I was using.

That being said, even with that fixed, I'm not able to complete the
patch process for the linux-raspberrypi kernel, I'm seeing and error
in do_patch itself, and it doesn't look related to the change in
question.

Are you seeing something similar ?

Never mind. I was carrying a local patch that was causing an issue
.. this is why you shouldn't try and work quickly while in a non-optimimal
environment.

I have the kernel patching here. For now, I'll send patch that follows your
original suggestion and I'll revisit the other workflows later.

[PATCH 2/6] linux-libc-headers: update to 5.x headers

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Updating the linux-libc-headers to the 5.x kernel variant to match
the latest reference kernel in the 2.7 release.

We have two patches refreshed for context changes, and three patches
dropped since they have been merged to the mainline kernel and are
no longer necessary.

-Subject: [PATCH 2/3] arm64/sve: ptrace: Fix SVE_PT_REGS_OFFSET definition
-
-SVE_PT_REGS_OFFSET is supposed to indicate the offset for skipping
-over the ptrace NT_ARM_SVE header (struct user_sve_header) to the
-start of the SVE register data proper.
-
-However, currently SVE_PT_REGS_OFFSET is defined in terms of struct
-sve_context, which is wrong: that structure describes the SVE
-header in the signal frame, not in the ptrace regset.
-
-This patch fixes the definition to use the ptrace header structure
-struct user_sve_header instead.
-
-By good fortune, the to structures are the same size anyway, so
-there is no functional or ABI change.

-From: Dave Martin <Dave.Martin@arm.com>
-Date: Tue, 11 Dec 2018 19:26:47 +0000
-Subject: [PATCH 3/3] arm64/sve: Disentangle <uapi/asm/ptrace.h> from
- <uapi/asm/sigcontext.h>
-
-Currently, <uapi/asm/sigcontext.h> provides common definitions for
-describing SVE context structures that are also used by the ptrace
-definitions in <uapi/asm/ptrace.h>.
-
-For this reason, a #include of <asm/sigcontext.h> was added in
-ptrace.h, but it this turns out that this can interact badly with
-userspace code that tries to include ptrace.h on top of the libc
-headers (which may provide their own shadow definitions for
-sigcontext.h).
-
-To make the headers easier for userspace to consume, this patch
-bounces the common definitions into an __SVE_* namespace and moves
-them to a backend header <uapi/asm/sve_context.h> that can be
-included by the other headers as appropriate.  This should allow
-ptrace.h to be used alongside libc's sigcontext.h (if any) without
-ill effects.
-
-This should make the situation unambiguous: <asm/sigcontext.h> is
-the header to include for the sigframe-specific definitions, while
-<asm/ptrace.h> is the header to include for ptrace-specific
-definitions.
-
-To avoid conflicting with existing usage, <asm/sigcontext.h>
-remains the canonical way to get the common definitions for
-SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
-kernel: relying on these being defined as a side effect of
-including just <asm/ptrace.h> was never intended to be safe.

https://errors.yoctoproject.org/Errors/Details/231923/

seems to be due to this. seems we need to get this define from
elsewhere have you encountered this?

> -Currently, <uapi/asm/sigcontext.h> provides common definitions for
> -describing SVE context structures that are also used by the ptrace
> -definitions in <uapi/asm/ptrace.h>.
> -
> -For this reason, a #include of <asm/sigcontext.h> was added in
> -ptrace.h, but it this turns out that this can interact badly with
> -userspace code that tries to include ptrace.h on top of the libc
> -headers (which may provide their own shadow definitions for
> -sigcontext.h).
> -
> -To make the headers easier for userspace to consume, this patch
> -bounces the common definitions into an __SVE_* namespace and moves
> -them to a backend header <uapi/asm/sve_context.h> that can be
> -included by the other headers as appropriate.  This should allow
> -ptrace.h to be used alongside libc's sigcontext.h (if any) without
> -ill effects.
> -
> -This should make the situation unambiguous: <asm/sigcontext.h> is
> -the header to include for the sigframe-specific definitions, while
> -<asm/ptrace.h> is the header to include for ptrace-specific
> -definitions.
> -
> -To avoid conflicting with existing usage, <asm/sigcontext.h>
> -remains the canonical way to get the common definitions for
> -SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
> -kernel: relying on these being defined as a side effect of
> -including just <asm/ptrace.h> was never intended to be safe.

> > - <uapi/asm/sigcontext.h>
> > -
> > -Currently, <uapi/asm/sigcontext.h> provides common definitions for
> > -describing SVE context structures that are also used by the ptrace
> > -definitions in <uapi/asm/ptrace.h>.
> > -
> > -For this reason, a #include of <asm/sigcontext.h> was added in
> > -ptrace.h, but it this turns out that this can interact badly with
> > -userspace code that tries to include ptrace.h on top of the libc
> > -headers (which may provide their own shadow definitions for
> > -sigcontext.h).
> > -
> > -To make the headers easier for userspace to consume, this patch
> > -bounces the common definitions into an __SVE_* namespace and moves
> > -them to a backend header <uapi/asm/sve_context.h> that can be
> > -included by the other headers as appropriate.  This should allow
> > -ptrace.h to be used alongside libc's sigcontext.h (if any) without
> > -ill effects.
> > -
> > -This should make the situation unambiguous: <asm/sigcontext.h> is
> > -the header to include for the sigframe-specific definitions, while
> > -<asm/ptrace.h> is the header to include for ptrace-specific
> > -definitions.
> > -
> > -To avoid conflicting with existing usage, <asm/sigcontext.h>
> > -remains the canonical way to get the common definitions for
> > -SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
> > -kernel: relying on these being defined as a side effect of
> > -including just <asm/ptrace.h> was never intended to be safe.

[PATCH 3/6] linux-yocto: introduce 5.0 versioned recipe

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Introducing the 5.0 linux-yocto reference kernel, which will become
the "latest" kernel as part of the spring yocto release.

qemu* has been built and sanity tested against this kernel, and it
is suitable to become the default build for the emulated references.

Some minor configuration cleanup was performed, but otherwise, things
are very similar to the 4.19 kernel config:

  7fdb966db86 (HEAD -> yocto-5.0) aufs4: kbuild patch
  c76b027a8b2 iosched: remove configs for removed legacy io schedules
  5d1f8102244 netfilter: drop removed config options
  8ff16f508f5 kernel-yocto: 5.0 kernel prep

Feature wise, this is a match for 4.19, with yaffs2 and aufs4 being
kept around for another release. Aufs is scheduled for removal in
the fall release.

[PATCH 4/6] lttng: add 5.x fixup patches to 2.10.8 release

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

lttng hasn't released 2.10.9, but the stable/2.10 branch
contains changes that we need to build against the 5.0
kernel.

We add them here as patches, and we can drop them in the
future when lttng is updated.

+Subject: [PATCH 1/9] Fix: signal: Distinguish between kernel_siginfo and
+ siginfo (v4.20)
+
+See upstream commit :
+
+  commit ae7795bc6187a15ec51cf258abae656a625f9980
+  Author: Eric W. Biederman <ebiederm@xmission.com>
+  Date:   Tue Sep 25 11:27:20 2018 +0200
+
+    signal: Distinguish between kernel_siginfo and siginfo
+
+    Linus recently observed that if we did not worry about the padding
+    member in struct siginfo it is only about 48 bytes, and 48 bytes is
+    much nicer than 128 bytes for allocating on the stack and copying
+    around in the kernel.
+
+    The obvious thing of only adding the padding when userspace is
+    including siginfo.h won't work as there are sigframe definitions in
+    the kernel that embed struct siginfo.
+
+    So split siginfo in two; kernel_siginfo and siginfo.  Keeping the
+    traditional name for the userspace definition.  While the version that
+    is used internally to the kernel and ultimately will not be padded to
+    128 bytes is called kernel_siginfo.
+
+    The definition of struct kernel_siginfo I have put in include/signal_types.h
+
+    A set of buildtime checks has been added to verify the two structures have
+    the same field offsets.
+
+    To make it easy to verify the change kernel_siginfo retains the same
+    size as siginfo.  The reduction in size comes in a following change.

+
+    signal: Remove SEND_SIG_FORCED
+
+    There are no more users of SEND_SIG_FORCED so it may be safely removed.
+
+    Remove the definition of SEND_SIG_FORCED, it's use in is_si_special,
+    it's use in TP_STORE_SIGINFO, and it's use in __send_signal as without
+    any users the uses of SEND_SIG_FORCED are now unncessary.
+
+    This makes the code simpler, easier to understand and use.  Users of
+    signal sending functions now no longer need to ask themselves do I
+    need to use SEND_SIG_FORCED.

+Subject: [PATCH 3/9] Fix: ext4: adjust reserved cluster count when removing
+ extents (v4.20)
+
+See upstream commit :
+
+  commit 9fe671496b6c286f9033aedfc1718d67721da0ae
+  Author: Eric Whitney <enwlinux@gmail.com>
+  Date:   Mon Oct 1 14:25:08 2018 -0400
+
+    ext4: adjust reserved cluster count when removing extents
+
+    Modify ext4_ext_remove_space() and the code it calls to correct the
+    reserved cluster count for pending reservations (delayed allocated
+    clusters shared with allocated blocks) when a block range is removed
+    from the extent tree.  Pending reservations may be found for the clusters
+    at the ends of written or unwritten extents when a block range is removed.
+    If a physical cluster at the end of an extent is freed, it's necessary
+    to increment the reserved cluster count to maintain correct accounting
+    if the corresponding logical cluster is shared with at least one
+    delayed and unwritten extent as found in the extents status tree.
+
+    Add a new function, ext4_rereserve_cluster(), to reapply a reservation
+    on a delayed allocated cluster sharing blocks with a freed allocated
+    cluster.  To avoid ENOSPC on reservation, a flag is applied to
+    ext4_free_blocks() to briefly defer updating the freeclusters counter
+    when an allocated cluster is freed.  This prevents another thread
+    from allocating the freed block before the reservation can be reapplied.
+
+    Redefine the partial cluster object as a struct to carry more state
+    information and to clarify the code using it.
+
+    Adjust the conditional code structure in ext4_ext_remove_space to
+    reduce the indentation level in the main body of the code to improve
+    readability.

+Subject: [PATCH 5/9] Fix: Remove 'type' argument from access_ok() function
+ (v5.0)
+
+See upstream commit :
+
+  commit 96d4f267e40f9509e8a66e2b39e8b95655617693
+  Author: Linus Torvalds <torvalds@linux-foundation.org>
+  Date:   Thu Jan 3 18:57:57 2019 -0800
+
+    Remove 'type' argument from access_ok() function
+
+    Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
+    of the user address range verification function since we got rid of the
+    old racy i386-only code to walk page tables by hand.
+
+    It existed because the original 80386 would not honor the write protect
+    bit when in kernel mode, so you had to do COW by hand before doing any
+    user access.  But we haven't supported that in a long time, and these
+    days the 'type' argument is a purely historical artifact.
+
+    A discussion about extending 'user_access_begin()' to do the range
+    checking resulted this patch, because there is no way we're going to
+    move the old VERIFY_xyz interface to that model.  And it's best done at
+    the end of the merge window when I've done most of my merges, so let's
+    just get this done once and for all.
+
+    This patch was mostly done with a sed-script, with manual fix-ups for
+    the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
+
+    There were a couple of notable cases:
+
+     - csky still had the old "verify_area()" name as an alias.
+
+     - the iter_iov code had magical hardcoded knowledge of the actual
+       values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
+       really used it)
+
+     - microblaze used the type argument for a debug printout
+
+    but other than those oddities this should be a total no-op patch.
+
+    I tried to fix up all architectures, did fairly extensive grepping for
+    access_ok() uses, and the changes are trivial, but I may have missed
+    something.  Any missed conversion should be trivially fixable, though.

+
+    btrfs: Remove fsid/metadata_fsid fields from btrfs_info
+
+    Currently btrfs_fs_info structure contains a copy of the
+    fsid/metadata_uuid fields. Same values are also contained in the
+    btrfs_fs_devices structure which fs_info has a reference to. Let's
+    reduce duplication by removing the fields from fs_info and always refer
+    to the ones in fs_devices. No functional changes.

Thanks Bruce!

Just to summarise where we're at:

a) The runtime stap tests fail everywhere, we probably need systemtap 
   patches.
b) Issue with KMACHINE_qemuarm = "qemuarma15" not working, blocks 
   qemuarm armv7 switch
c) qemumips and qemuppc:

I did notice that the AB log seems to show 4.19 being built for this,
is that just a red herring ?

Yes, well spotted, perf is failing to build with the 4.19 kernel.

Thanks for the other fixes, they improve things a lot. This brings us
down to the above perf issue with 4.19 and:

a) KMACHINE_qemuarm = "qemuarma15" not working?

b) qemuarm64 graphics not working with 5.0

Getting there! :)

Cheers,

Richard

I mentioned on IRC that the kernel parts are working for me, and
by that, the mapping to the qemuarma15 bsp definition and hence
configs is correct.

I seem to be missing some machine definition parts to get a valid
userspace to work against that new kernel .. is there a series of
patches that I'm missing ?

I don't think I've ever had this working, but I'll have a look at it as well.
But more eyes on something like this, will definitely help.

There has been some confusion/mixup. What I want to do is add a
qemuarmv5 which is the current qemuarm and then switch qemuarm to be
the a15 based one.

Something like:

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/t222&id=981788cde4ddae41b5dac7d2aab771939cf2a28f

I put KMACHINE mappings in the machine definitions, this patch isn't
well tested as yet and builds on the qemuarma14 patch in -next.

Jon won't get to that until Monday and I'm travelling so will be a bit
disrupted. I'm testing what I can before I leave.

qemumarm64 graphics works with the 4.19 kernel but not 5.0.

The only other issue I'm aware of is stap failing on qemuarm (old v5
version).
