[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

Mantic and Jammy built successfully in all supported architectures.
(riscv64 fails, but it also fails on mantic/jammy-release; it's OK.)

Uploaded! 
Thanks

Bug description:
  [Impact]
  Linux kernel 6.2 includes patches with structural changes that may render the 
crash utility in Mantic (release kernel 6.5) and Jammy (HWE kernel 6.5) unable
  to parse the dump file. For example (there are more, in other areas):
  ==
  d122019bf061 mm: Split slab into its own type
  401fb12c68c2 mm: Differentiate struct slab fields by sl*b implementations
  07f910f9b729 mm: Remove slab from struct page
  0d9b1ffefabe arm64: mm: make vabits_actual a build time constant if possible
  e36ce448a08d mm/slab: use kmalloc_node() for off slab freelist_idx_t array 
allocation
  130d4df57390 mm/sl[au]b: rearrange struct slab fields to allow larger rcu_head
  ac3b43283923 module: replace module_layout with module_memory
  b69f0aeb0689 pid: Replace struct pid 1-element array with flex-array
  ==

  [Fix]
  It is advisable to adopt commits that address the structural changes:
  - 10 patches from crash 8.0.1 into Jammy
  - 02 patches from crash 8.0.2 into Jammy
  - 12 patches from crash 8.0.3 into Jammy/Mantic
  - 12 patches from crash 8.0.4 into Jammy/Mantic

  [Test Plan]

  On Jammy (LTS), which provides HWE (6.5) and release/GA (5.15) kernels,
  perform testing on both HWE (verify fixes) and GA (verify no regressions).

  There are detailed/per-commit test plans in the attachments:
  `crash_jammy_test_plan.txt.txt` and `crash_lunar_test_plan.txt`.

  A. Test the live mode (live-system form; without a dumpfile), and
  B. Test the dump mode (dumpfile form: sysrq-trigger/makedumpfile/crash):

  1. Install the required packages and then proceed to reboot the machine.
  # sudo apt install crash linux-crashdump -y
  # reboot
  2. To check the status of kdump, use the `kdump-config show` command.
  # kdump-config show
  DUMP_MODE:kdump
  USE_KDUMP:1
  KDUMP_COREDIR:/var/crash
  crashkernel addr: 0x6400

  kexec command:

reset_devices systemd.unit=kdump-tools-dump.service nr_cpus=1 irqpoll 
usbcore.nousb" --initrd=/var/lib/kdump/initrd.img /var/lib/kdump/vmlinuz
  3. To trigger a crash dump forcefully, execute the `echo c | sudo tee 
/proc/sysrq-trigger` command.
  4. Download the kernel .ddeb file, which will be used for analyzing the dump 
file.
  # sudo -i
  # cd /var/crash
  # pull-lp-ddebs linux-image-unsigned-$(uname -r)
  # dpkg-deb -x linux-image-unsigned-$(uname -r)-*.ddeb dbgsym-$(uname -r)
  5. Utilize the "crash" utility to parse and analyze the dump file.

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

Partial review of the Jammy debdiff.
(Still in progress.)

Started with Jammy's patches 0012-0036, which are Mantic's patches 0001-0024 
(already reviewed).
Most patches are identical, and some have context-line changes, as expected 
(8.0.2/8.0.0 delta).
Just had a few changes.

$ for ((i=1; i<=24; i++)); do 
echo "PATCH $i"
echo
diff -U0 \
  mantic/crash-8.0.2/debian/patches/lp2038249-$(printf '%04d' $i)-*.patch \
  jammy/crash-8.0.0/debian/patches/lp2038249-$(printf '%04d' 
$((i+12)))-*.patch
echo
  done 2>&1 | less

patch 13
actually a backport, context line changes

patch 4
likewise

patch 8
augment backport notes

patch 11
actually a backport, context line changes, more
indentation issue, fixed

patch 36 (same note as patch 24/mantic)

Today, I tackled the Mantic debdiff (made only a few changes; below).

It's now currently building in a PPA for all supported architectures,
(ppa:mfo/lp2038249) and if all goes well I will upload it to Mantic.

Thanks!

changelog OK
DEP3 tags OK

I reviewed each commit, with the exception of the big code additions
(patches 8,16: for maple tree and module memory layout): all look OK.

I fixed up patch 24, which is originally 2 trivial and short changes,
but had like ~3800 lines of indentation/formatting changes included
(certainly this wasn't intented, and mistakes happen; so I fixed it).

debian/patches/lp2038249-0024-Fix-compilation-error-and-warning-with-gcc-4.8.5.patch

We can all learn from this -- I will check .patch files with diffstat!

I also just augmented backport notes (thanks for those) to indicate
which functions/hunks had context lines modified/adjusted/refreshed,
since the patch is big (patch 15), and clarify variables (not) used.

-+[chengen - modify x86_64.c context]
++[chengen - modify context in x86_64.c: x86_64_ORC_init() and 
x86_64_get_framesize()]

-+[chengen - initialize init_tss to zero in xen_hyper.c]
++[chengen - initialize only init_tss to zero in xen_hyper.c (there is 
no stack_base yet)]

Very importantly, the detailed test plan will be key to validate the
changes are working correctly, considering their number and size.
Thanks again for it!

  [Test Plan]

  On Jammy (LTS), which provides HWE (6.5) and GA (5.15) kernels,
  perform testing on both HWE (verify fixes) and GA (verify no regressions).

  There are detailed/per-commit test plans in the attachments:
  `crash_jammy_test_plan.txt.txt` and `crash_lunar_test_plan.txt`.

  And the general sysrq-trigger/makedumpfile/crash test:

  1. Install the required packages and then proceed to reboot the machine.
  # sudo apt install crash linux-crashdump -y
  # reboot
  2. To check the status of kdump, use the `kdump-config show` command.
  # kdump-config show

  [Test Plan]

  
  There are detailed/per-commit test plans in the attachments:
  `crash_jammy_test_plan.txt.txt` and `crash_lunar_test_plan.txt`.

  And the general sysrq-trigger/makedumpfile/crash test:

  1. Install the required packages and then proceed to reboot the machine.
  # sudo apt install crash linux-crashdump -y
  # reboot
  2. To check the status of kdump, use the `kdump-config show` command.
  # kdump-config show
  DUMP_MODE:kdump
  USE_KDUMP:1

reset_devices systemd.unit=kdump-tools-dump.service nr_cpus=1 irqpoll 
usbcore.nousb" --initrd=/var/lib/kdump/initrd.img /var/lib/kdump/vmlinuz
  3. To trigger a crash dump forcefully, execute the `echo c | sudo tee 
/proc/sysrq-trigger` command.
  4. Download the kernel .ddeb file, which will be used for analyzing the dump 
file.
  # sudo -i
  # cd /var/crash
  # pull-lp-ddebs linux-image-unsigned-$(uname -r)
  # dpkg-deb -x linux-image-unsigned-$(uname -r)-*.ddeb dbgsym-$(uname -r)
  5. Utilize the "crash" utility to parse and analyze the dump file.

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

The crash 8.0.4 merge in bug 2047861 looks good, it passed
autopkgtests/manual tests, and is now waiting on review/sponsoring for
Noble.

Once accepted/released to Noble, this should unblock the SRUs (which have 
patches from 8.0.4).
I'll continue the SRU debdiff reviews for now.

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

Hi Chengen!

Thank you very much for the detailed test plan! It's really good.

Apologies for the extended delay in getting back to your changes.

There are some points to address in the debdiffs. In order of
importance:

1) The debdiff for Lunar and Jammy (equivalent) are for kernel 6.2, but
Jammy now has the 6.5 HWE kernel [1] too.

I suspect that the users/original reporter that looked for HWE kernel
support back at 6.2 would likely switch to 6.5 too, so it would be
beneficial and time saving to incorporate the 6.5 patches now, since you
already have them in the Mantic debdiff [2]. What do you think?

2) There are 12 patches from crash 8.0.4 [3] in the Mantic debdiff, but
these are not yet in Ubuntu (not even in Noble, the development
release), which has 8.0.3.

I will provide another Merge from Debian to crash, since upstream has now 
released 8.0.4 and Debian pulled it in. 
But for the future it's important to keep this in mind, as it may save the time 
of a review round trip, and more debdiff/build/test work.

3) The version numbers are incorrect for stable releases.

Please see [4].

In general, you should increment by 'ubuntu0.1' in stable releases (and
'ubuntu1' in the development release), and if multiple stable releases
have the same package version, increment by 'ubuntu0.YY.MM.1' to
differentiate among them.

i.e.,

$ rmadison -a source crash
...
 crash | 8.0.0-1ubuntu1 | jammy  | source
 crash | 8.0.0-1ubuntu1 | lunar  | source
 crash | 8.0.2-1ubuntu1 | mantic | source
 crash | 8.0.3+ds1-3ubuntu1 | noble  | source

debdiffs:

$ grep -o '.crash (.*)' *.debdiff
lp2038249-crash-jammy.debdiff:+crash (8.0.0-1ubuntu2)
lp2038249-crash-jammy.debdiff: crash (8.0.0-1ubuntu1)
lp2038249-crash-lunar.debdiff:+crash (8.0.0-1ubuntu2)
lp2038249-crash-lunar.debdiff: crash (8.0.0-1ubuntu1)
lp2038249-crash-mantic.debdiff:+crash (8.0.2-1ubuntu2)
lp2038249-crash-mantic.debdiff: crash (8.0.2-1ubuntu1)

per [4]:

jammy: 8.0.0-1ubuntu1.22.04.1
lunar: 8.0.0-1ubuntu1.23.04.1
mantic: 8.0.2-1ubuntu1.1

4) The changes to 'debian/Makefile.ori' are not listed or explained
in the changelog.

If this is unintended (i.e., post-build noise in debian/, it should
be removed), but if it's intended/required, then it should be listed
and slightly documented, please.

5) The itemization in changelog is a bit weird.

This is a style/cosmetic suggestion, not a requirement, but in practice,
when you have multiple patches, the first item is the description with
the LP bug number, and the sub items are the patches; e.g.,

  +  * Fix the dump file parsing issue arises from structural changes in Linux
  +kernel 6.5 (LP: #2038249)
  +- d/p/lp2038249-arm64-handle-vabits_actual-symbol-missing-case.patch
  +- 
d/p/lp2038249-x86_64-Fix-for-move-of-per-cpu-variables-into-struct.patch
  +- ... more patches

6) The patches are not numbered

Again, a style/cosmetic suggestion; but it does help with parsing/organization
over time for longer patch series like this one.

You can use 'quilt rename' and a shell loop to easily adjust this, of course.
Please let me know if you would like some help (I don't think so, but just in 
case!).

7) Special thanks for paying attention to 'upstream/backport' keyword in
the 'Origin:' DEP-3 header!

$ grep -ho 'Origin: [^ ]*' *.debdiff | sort | uniq -c
 12 Origin: backport,
 66 Origin: upstream,

...

So, for now, if you have a chance, please feel free to adjust the debdiffs,
and I'll work on merging 8.0.4 in Noble, to unblock the needed 12 patches.

Thanks again,
Mauricio

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Chengen Du]

Hi, I'm focusing on resolving all issues caused by structural changes
rather than solely ensuring the crash utility functions across different
kernel versions. The patch set will be extensive and require additional
time for backporting and testing. I'll provide the new patch as soon as
possible.

Crash 8.0.3 should soon be available in Debian, and we can merge it into Noble
with a few more recent fixes for the 6.x kernels (Noble is 6.5+), which we'll
need to SRU in older releases too (Mantic is 6.5, Lunar is 6.2, Jammy HWE is 
6.2 now, will be 6.5).

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

Hi Chengen,

Thanks for the great work for these SRUs.

I'd like to suggest an update/improvement to the Test Plan section.
Even though crash is so broken that it can't even open a file,
once it starts working at all, it would be important to check
that it is working _correctly_.

So, please, could you add verifications for basic correctness
of the commands being addressed per patch (for GA and HWE)?
e.g., kmem -s|-S, module memory layout, etc.

And I had questions on 2 patches:

Patch 3:
---

 31 +* commit e36ce448a08d removed kmem_cache.freelist_cache in 6.1,
 32 +* so use freelist_size instead.
 33  */
 34 -   if (MEMBER_EXISTS("kmem_cache", "freelist_cache")) {
 35 +   if (MEMBER_EXISTS("kmem_cache", "freelist_size")) {

This is an inconditional change before/after 6.1, which thus could
impact Jammy, as it ships both 5.15 and 6.2 kernels.

However, it seems the (new value) attribute 'freelist_size' already
exists, so it should be fine in Jammy _if_ 5.15 has it too.

Could you please confirm?

Patch 5:
---

Some of this backport's context update is because this patch is not included,
and it would also fit the 6.2 criteria (changes in 6.1). It seems only code
adds though, not sure how it changes any behavior (or more patches needed).

Can you clarify if it's not really needed for 6.5? 
(I haven't followed the maple tree closely, but the commit message suggests 
it's important.)

If it's not needed _right_ now, i.e., if this SRU is priority, and crash
at least _works_ (which is a good improvement), I think it would be fine
to add it later.

commit 872cad2d63b3a07f65323fe80a7abb29ea276b44
Author: Tao Liu 
Date:   Tue Jan 10 14:56:27 2023 +0800

Port the maple tree data structures and functions

There have been two ways to iterate vm_area_struct until Linux 6.0:
 1) by rbtree, aka vma.vm_rb;
 2) by linked list, aka vma.vm_{next,prev}.
However with the maple tree patches[1][2] in Linux 6.1, vm_rb and
vm_{next,prev} are removed from vm_area_struct. The vm_area_dump()
in crash mainly uses the linked list for vma iteration, which will
not work for this case. So the maple tree iteration needs to be
ported to crash.

This patch 5 is also big, adding a lot, anyway, but it goes to gdb-10.2.patch,
which only changed context lines for the backport, indeed.

A pure-code review against upstream seems a big effort (~2000 lines, I managed
up to ~1000, and it seems to match upstream).

I guess this patch will be reasonably verified if the crash commands to show 
module memory layout on kernel 6.4+ (6.5 in our case) run correctly.

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Mauricio Faria de Oliveira]

The version in Noble is still the same as in Mantic, and Debian does not
have a newer version either to sync/merge [1], so it apparently will not
change soon.

Let's proceed with the Mantic debdiff plus changes for Noble.

Changes:
- Modified d/changelog style to '* Description (LP: #)' entry with '- 
d/p/.patch' sub-entries (more common).
- Numbered the patches (1-7).

Great work on DEP-3 headers, thank you! (Bug-Ubuntu, Origin, and
backport notes; all matching.)

I checked there have been no changes from these patches upstream (i.e.,
fix-up commits to add; except for patch 5 mentioned later, with another
strategy).

I'll attach the updated debdiff for now (keeping your name in signature
line, if you don't mind, as I haven't done serious changes).

Submitted bug [1] (wishlist) to Debian maintainer to update crash from
8.0.2 to 8.0.3 (released April/2023) in sid/unstable.

With this we could merge a smaller set of changes later on.

[Paride Legovini]

Hi, so AIUI then plan here is the following:

- Wait for Noble to be open for development;
- You'll prepare a Noble debdiff to be sponsored;
- Once fixed in Noble, we'll move to review/sponsor the SRUs.

Given that Noble is still frozen, and no Noble debdiff is present, I
take there is nothing to sponsor here for now.

[Kernel-packages] [Bug 2038249] Re: The dump file parsing issue arises from structural changes in Linux kernel 6.2

[Heitor Alves de Siqueira]

As this will need fixing in the development release, I'll re-subscribe
the ubuntu-sponsors team. After this has been fixed there, we can take a
look at the SRU for the other stable releases.

Thanks, Chengen!

  401fb12c68c2 mm: Differentiate struct slab fields by sl*b implementations
  07f910f9b729 mm: Remove slab from struct page
  0d9b1ffefabe arm64: mm: make vabits_actual a build time constant if possible
  e36ce448a08d mm/slab: use kmalloc_node() for off slab freelist_idx_t array 
allocation
  130d4df57390 mm/sl[au]b: rearrange struct slab fields to allow larger rcu_head
  ac3b43283923 module: replace module_layout with module_memory

  [Test Plan]
  1. Install the required packages and then proceed to reboot the machine.
  # sudo apt install crash linux-crashdump -y
  # reboot
  2. To check the status of kdump, use the `kdump-config show` command.
  # kdump-config show
