[Thadeu Lima de Souza Cascardo]

That is failing with 4.17.0-9, the kernel is cosmic, as well. Does that
contain that same unprivileged-mknod change?

Thanks.

snapd will need that too, though it doesn't even support kexec yet,
which breaks systemctl kexec already.

[Bug 1783881] Re: ltp-syscalls: msgstress03 fails because systemd limits number of processes

[Thadeu Lima de Souza Cascardo]

The number of processes (in systemd, tasks).

The command below works for me.

Now, should we change the default on our test systems? Running under
systemd-run does not look like a good option.

# systemd-run -p TasksMax=100 ./testcases/bin/msgstress03

[Bug 1789436] [NEW] pmtu.sh fails on 4.18 kernel

[Thadeu Lima de Souza Cascardo]

Public bug reported:

pmtu.sh is a network selftest that was introduced on 4.17. It is
currently failing on 4.18. After revert of ccd740cbc6 "vti6: Add pmtu
handling to vti6_xmit.", it passes.

The fail is in the nature of holding netdevices refcounts, so some
network operations start hanging, including the loading and removal of
network modules.

[Bug 1788603] Re: libvirt fails with failure to open mount namespace

[Thadeu Lima de Souza Cascardo]

So, investigated this into an apparmor difference between 4.17 and 4.18.
This is due to commit 338d0be437ef10e247a35aed83dbab182cf406a2
("apparmor: fix ptrace read check").

libvirtd here is using only trace, and not read. The patch below for
libvirtd apparmor policy fixes it for me.

[Bug 1788603] [NEW] libvirt fails with failure to open mount namespace

[Thadeu Lima de Souza Cascardo]

Public bug reported:

$ virsh start cosmic-i386
error: Failed to start domain cosmic-i386
error: internal error: child reported: Kernel does not provide mount namespace: 
Permission denied


Happens with 4.18 only, 4.17 is fine.

27013 openat(AT_FDCWD, "/proc/27012/ns/mnt", O_RDONLY) = -1 EACCES
(Permission denied)

Opening a self or parent mount namespace works fine as tested with cat
/proc/self/ns/mnt and cat /proc/self/$$/mnt. Still investigating.

[Bug 1787972] [NEW] Cosmic update to 4.17.16 stable release

[Thadeu Lima de Souza Cascardo]

Public bug reported:


SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The 4.17.16 upstream stable
   patch set is now available. It should be included in the Ubuntu
   kernel as well.

   git://git.kernel.org/

TEST CASE: TBD

[Thadeu Lima de Souza Cascardo]

Just manually giving acpi_rsdp parameter to kexec will make it work, so
it should be automatically given despite the xloadflags not being
present in bzImage.

[Bug 1787596] [NEW] kexec can't give acpi_rsdp parameter to efi boot

[Thadeu Lima de Souza Cascardo]

Public bug reported:

When doing kexec on trusty, it will look for the xloadflags on the
bzImage, but won't find it on trusty kernels. That will break kexec on
EFI systems, requiring acpi_rsdp parameter to be given manually.

[Bug 1765660] Re: Ubuntu 18.04 [ briggs ]: "ipcs" command fails with error "invalid structure member offset" in crash prompt.

[Thadeu Lima de Souza Cascardo]

** Description changed:

  [Impact]
- Some analysis won't be possible on new kernels (hwe-edge on xenial, for 
example; or the standard bionic kernel).
+ Some analysis won't be possible on new kernels. In this case, ipcs command 
could not be used with the bionic GA kernel on ppc64le.
  
  [Test Case]
  The ipcs command has been run after the fix was applied to crash, on a live 
amd64 system, with success.
  
  [Regression Potential]
- Analysis of crashed kernels will require that the crash file be moved to a 
system where crash doesn't have the regression. The patch, however, should 
touch only the broken command, and has been tested.
+ New crash versions may have bugs and some commands not work with older 
kernels. The smoke test helps a little, but more testing may be desirable.
+ 
+ In case of regressions, analysis of kernel dumps will require that the
+ crash file be moved to a system where crash doesn't have the regression.
+ But live analysis won't be possible in that case.
+

[Bug 1785686] Re: makedumpfile not able to use compression in trusty kernel 3.13 (fallback to 'cp')

[Thadeu Lima de Souza Cascardo]

For the record, Guilherme and I concluded that when dumping a kexec
kernel, there may be leftover memory from the previous kernel which
causes the dump to be corrupted. That was after I ran some tests that
showed that when booting a 3.13.0-137, kexecing a 3.13.0-85, then
dumping, the dump would contain 3.13.0-137 versions. And Guilherme
confirmed that kexec was used to boot kernels once in a while during the
tests.

As the test results from Guilherme include boots with kexec and without
it, and the results were not consistent, the suggestion is that multiple
dumps be taken only when cold booting a 3.13 kernel, using makedumpfile
shipped from trusty-updates. And that those be verified with crash.

Cascardo.

This was about analyzing a 4.13 kernel on xenial, which meant a linux-
hwe kernel, now on version 4.15.0-30.32~16.04.1.

Can you verify the fix with a linux-hwe kernel?

[Bug 1785686] Re: makedumpfile not able to use compression in trusty kernel 3.13 (fallback to 'cp')

[Thadeu Lima de Souza Cascardo]

I managed to create successful compressed dumps with trusty makedumpfile
Version: 1.5.5-2ubuntu1.6, with both a linux-3.13.0-137 and a
linux-3.13.0-85. That was on an amd64 kvm system.

So, this tells me this is system dependent, and we need more information
on its configuration, and all the help and data we can gather to debug
this, as it's likely we won't be able to easily reproduce it.

[Bug 1765660] Re: Ubuntu 18.04 [ briggs ]: "ipcs" command fails with error "invalid structure member offset" in crash prompt.

[Thadeu Lima de Souza Cascardo]

Sorry about the lying in the regression potential. It probably referred
to a previous backport attempt, that only applied the respective patch.
As we discussed a few months ago, kexec/kdump/crash would be backported
because of their relationship with the linux package, and its siblings
linux-lts, linux-hwe, etc. That doesn't mean we shouldn't or can't test
the packages more thoroughly. That's why I introduced ADT support to
kdump, and would like to work on more testing for those packages. Right
now, I can do more manual testing for this, and add my results to the
bug.

Thanks for bringing this up.
Cascardo.

[Bug 1785211] [NEW] Cosmic update to 4.17.12 stable release

[Thadeu Lima de Souza Cascardo]

Public bug reported:


SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The 4.17.12 upstream stable
   patch set is now available. It should be included in the Ubuntu
   kernel as well.

   git://git.kernel.org/

TEST CASE: TBD

   The following patches from the 4.17.12 stable release shall be
applied:

[Bug 1783877] Re: ltp-syscalls: sgid inheritance for non-directories behavior changed

[Thadeu Lima de Souza Cascardo]

So, this won't be "fixed" in the kernel, as it has security
implications.

The ltp test has been fixed to ignore this specific behavior. It has
been committed already to ltp, so closing on the test side as well.

3c87ef2961dedb10d1f674c6a530e00dbab8ec1b ("open|creat: skip S_ISGID
check on files created by non-group members") is the ltp commit.

[Bug 1765660] Re: Ubuntu 18.04 [ briggs ]: "ipcs" command fails with error "invalid structure member offset" in crash prompt.

[Thadeu Lima de Souza Cascardo]

Okay, so Manoj was confused as he looked into a linux commit, while we
are talking about crash here. That explains the confusion. On the IBM
side, it seems to have been closed either because the fix has already
landed on cosmic, or because of the ppa test.

[Bug 1765660] Re: Ubuntu 18.04 [ briggs ]: "ipcs" command fails with error "invalid structure member offset" in crash prompt.

[Thadeu Lima de Souza Cascardo]

Yeah, this doesn't sound right. Bionic has 7.2.1-1, while the fix has
been applied to 7.2.2-1. The verification mentioned on comment #7 was
against a ppa.

We can't ask IBM to properly verify it on bionic until we get this
package on -proposed. Let me move the task back to In Progress.

Thanks.
Cascardo.

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state

[Thadeu Lima de Souza Cascardo]

Ah, I see what you meant about the PHB. The two new attached logs are
not at all similar to the original ones, maybe pointing to an unrelated
problem.

As for the sosreport, the /sys/ directory is missing almost everything
that I would need to debug this. So, I need any other form of collecting
/sys/. Maybe just tar czf lp1778844_sys.tar.gz /sys/.

Cascardo.

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state

[Thadeu Lima de Souza Cascardo]

Hi, Hari.

The sosreport should be enough. I sent that message without an updated
view of the bug, so did not notice the attachments. They came on the
same day I asked. Just realized now that they are present. Let me look
at them.

Now, if kdump works with MODULES=most, then the PHB initialization could
require a module that is not in the initramfs. I know some Intel systems
require their vmd module that adds a new PCI domain. Is there some new
pci host module these days on these new Power systems?

Regards.
Cascardo.

[Bug 1783881] [NEW] ltp-syscalls: msgstress03 fails because systemd limits number of processes

[Thadeu Lima de Souza Cascardo]

Public bug reported:

As systemd limits the number of processes, this test will fail because
it can't fork enough processes. That is limited to when the test is run
after logging as user 1000, then running sudo. I guess that logging as
root may not cause this to happen.

# ./testcases/bin/msgstress03 
Fork failed (may be OK if under stress)
Fork failed (may be OK if under stress)
msgstress031  TFAIL  :  msgstress03.c:157:  Fork failed (may be OK if under 
stress)

[Bug 1783877] [NEW] ltp-syscalls: sgid inheritance for non-directories behavior changed

[Thadeu Lima de Souza Cascardo]

Public bug reported:

ltp syscalls open10 and and creat08 try to create an sgid executable
file inside a sgid directory owned by a group whose members do not
include the process user.

That used to work up to commit 0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7
("Fix up non-directory creation in SGID directories").

This was backported to 4.17.9 and so affects the current kernel in
cosmic proposed, and breaks such ltp tests.

[Bug 1783880] [NEW] ltp-syscalls: fallocate05 fails with btrfs on ppc64el

[Thadeu Lima de Souza Cascardo]

Public bug reported:

This affects at least bionic and cosmic proposed kernels.

This affects only ppc64el. My guess is the reason is the page size. In
fact, changing the fallocate size to 64KiB, the test works.

[Bug 1783201] [NEW] Cosmic update to 4.17.9 stable release

[Thadeu Lima de Souza Cascardo]

Public bug reported:


SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The 4.17.9 upstream stable
   patch set is now available. It should be included in the Ubuntu
   kernel as well.

   git://git.kernel.org/

TEST CASE: TBD

   The following patches from the 4.17.9 stable release shall be
applied:

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state

[Thadeu Lima de Souza Cascardo]

I have managed to test kdump and initramfs with MODULES=dep on an
emulated nvme, using qemu. Both worked just fine. The sysfs tree seems
reasonable too, in respect to how initramfs finds the necessary modules.

So, I would really need the specific details on that failure case, that
is, the sysfs tree and all the rest I requested in the previous message.

Thank you.
Cascardo.

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state

[Thadeu Lima de Souza Cascardo]

As we use MODULES=dep for kdump initrd, that might fail to include the
proper modules. It would be a bug on initramfs-tools-core.

Can you change /etc/initramfs-tools/initramfs.conf to have MODULES=dep
instead of MODULES=most and run mkinitramfs -o /tmp/initrd.img `uname
-r`, then send me output?

Also, I need the data usually collected for kernel bugs. /sys/ at least
comes to mind, but also complete dmesg after normal boot and some other
important files to detect root mountpoint, like /etc/fstab,
/proc/cmdline and /proc/mounts.

Thank you.
Cascardo.

  == Comment from Hari Krishna Bathini ==
  
  There are quite a few commits (all available upstream) that are needed for
  crash tool to work fine. I think the right thing to do here would be to use
  the latest crash tool version 7.2.0 to go with the kernel update. Also, the
  below commit would be needed on top of 7.2.0 crash utility:
  
-   commit c8178eca9c74f81a7f803a58d339635cc152e8d9

[Bug 1776967] Re: glibc pkeys test fail on powerpc

[Thadeu Lima de Souza Cascardo]

Florian, thanks for the heads-up and for pursuing this. I read some of
the links pointed out in that bug, and I see there is much to improve
yet, and 4.17 might not have the best pkeys story for powerpc. Maybe we
should just disable that test in the meantime.

About the particular problem we saw here in our case:

FAIL: misc/tst-pkey
original exit status 1
error: ../sysdeps/unix/sysv/linux/tst-pkey.c:200: pkey_alloc: No space left on 
device
error: 1 test failures

Running this on a system I got hold onto, I got the same issue.

Likely, this is due to pkey_disabled from
arch/powerpc/include/asm/pkeys.h:mm_pkey_alloc, which would be the case
as in arch/powerpc/mm/pkeys.c:pkey_initialize:

if (!pkey_mmu_enabled() || radix_enabled() || !pkeys_total)
static_branch_enable(_disabled);
else
static_branch_disable(_disabled);

I don't think EINVAL should be returned instead. Returning ENOSPC in
such a case seems reasonable, and any pkey code should be able to handle
that case. So, one more thing to fixup in the tests expectations.

Cascardo.

[Bug 1772024] Re: linux 4.13.0-42.47 ADT test failure with linux 4.13.0-42.47 (nbd-smoke-test)

[Thadeu Lima de Souza Cascardo]

** Description changed:

+ [Impact]
+ nbd-server will crash when a client connects to it, if it was started without 
a server name. It may also leak fds if fork fails.
+ 
+ [Test Case]
+ Running the server with an empty config file and an image on the command 
line, and then starting a local client will crash the server. After the fix, it 
doesn't crash anymore, and a filesystem may be created and used after that.
+ 
+ [Regression Potential]
+ The fix also implies a small package change, to use quilt. It has built just 
fine and many tests have been run on top of those packages and no failure 
seemed to be the result of those userspace changes, but known failures in the 
kernel driver.

[Bug 1776967] [NEW] glibc pkeys test fail on powerpc

[Thadeu Lima de Souza Cascardo]

Public bug reported:

powerpc introduced protection keys support, now present on 4.17 kernel.

glibc has a tst-pkey that fails on powerpc, and that needs further
investigation.
