IBM is requesting these nine patches to be SRU'd to Bionic. IBM found
that the current Bionic kernel contains a problem related to qla2xxx
driver which causes the following:

== Regression Potential ==
Medium. There are nine patches in this pull request. They are not specific
to a
paticular arch, but they are specific to qla2xxx.
== Test Case ==
A test kernel was built with these patches and tested by IBM.
IBM states the test kernel resolved the bug.

== Regression Potential ==
Medium. There are nine patches in this pull request. They are not specific
to a
paticular arch, but they are specific to qla2xxx.
== Test Case ==
A test kernel was built with these patches and tested by IBM.
IBM states the test kernel resolved the bug.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
--- Comment From dougm...@us.ibm.com 2018-05-25 07:47 EDT---
We have installed this kernel and verified that it is working. We are not
seeing the panics.
I'm not certain how to change the tag from this end, but I consider this
verified now.
Thanks.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

== SRU Justification ==
IBM is requesting these nine patches to be SRU'd to Bionic. IBM found
that the current Bionic kernel contains a problem related to qla2xxx
driver which causes the following:

== Regression Potential ==
Medium. There are nine patches in this pull request. They are not specific
to a
paticular arch, but they are specific to qla2xxx.
== Test Case ==
A test kernel was built with these patches and tested by IBM.
IBM states the test kernel resolved the bug.

Using kernel from http://kernel.ubuntu.com/~jsalisbury/lp1770003, I have
confirmed that the disks are discovered and I am running some scenarios now.
Doing portdisable/portenable from the FC switch occasionally, while running HTX
I/O load. No problems seen so far.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
Hello,
I'll build a test kernel with you're backports. They all apply to the
current Bionic kernel in the master-next branch: version 4.15.0-22.23.
The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1770003
Can you test this kernel and see if it resolves this bug?
Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the
linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the
linux-image-unsigned, linux-modules and linux-modules-extra .deb packages.
Thanks in advance!

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
Hi,
Since Manoj's kernel didn't work, I created a kernel with the fixes
above and it is working on ppc64el (on a 24 hours test).
These are the patches I added:
scsi: qla2xxx: Fixup locking for session deletion
scsi: qla2xxx: Fix double free bug after firmware timeout
scsi: qla2xxx: Prevent relogin trigger from sending too many commands
scsi: qla2xxx: Fix warning in qla2x00_async_iocb_timeout()
scsi: qla2xxx: Don't call dma_free_coherent with IRQ disabled.
scsi: qla2xxx: Serialize session free in qlt_free_session_done
scsi: qla2xxx: Serialize session deletion by using work_lock
scsi: qla2xxx: Remove unused argument from qlt_schedule_sess_for_deletion()
scsi: qla2xxx: Fix session cleanup for N2N
You can find the patches at
https://github.com/leitao/linux/commits/bionic
Is it possible to add these patches in this next SRU?

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
I also created a vimdiff of both logs, and I noted something that caused
the whole difference later:
On the OK kernel, I see:
[0001:03:00.0]-001d: : Found an ISP2532 irq 41 iobase 0xdb2a8857.
On the NOK kernel I see:
[0001:03:00.0]-001d: : Found an ISP2532 irq 41 iobase 0x6baeaf0e.
Later, The addresses are different again:
OK Kernel:
[0001:03:00.1]-001d: : Found an ISP2532 irq 42 iobase 0xc67eaba1
NOK Kernel:
[0001:03:00.1]-001d: : Found an ISP2532 irq 42 iobase 0x507ae35c
After that, the OK kernel follows with:
[0001:03:00.0]-580e:2: Asynchronous P2P MODE received
[0001:03:00.0]-18b9:2: Format 1: VP[0] enabled - status 0 - with port id

[0001:03:00.0]-5875:2: Format 1: Remote WWPN 20:05:00:05:1e:02:da:3e.
While the NOK kernel follows with:
[0001:03:00.0]-5809:2: LIP occurred (f700)
[0001:03:00.0]-580c:2: LIP reset occurred (f7f7).
Later, when the OK kernel seems to detect something, as:
[0001:03:00.0]-289f:2: Device wrap (030a00).
[0001:03:00.0]-28d8:2: qla24xx_fcport_handle_login 50:05:07:68:02:16:5e:37

The NOK kernel just prints:
[0001:03:00.0]-107ff:2: Async-gpnft hdl=2 FC4Type 8.

Manoj,
Do you have the git tree you used to build this kernel? I would like to
take a look if any backport was missing.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
Sorry, my apologies .. I misunderstood your requirement ..again.. I have
bumped the kernel version to 4.15.0-21 from 4.15.0-20. After you install
you should be able to choose between old and new kernel. It will take
approx 5hrs for the kernel to be published in the PPA.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
you could preseed your installer to install the kernel in the PPA. I
have not tested the instructions below.. but should give you an idea how
to preseed. From your comment above looks like you might not have a
booting system to be able to install the new kernel etc.
Assuming you are using a netboot install.
-- tell installer grub to use preseed --
Edit ubuntu-installer/ppc64el/grub/grub.cfg and add your preseed file. Like for
example:
menuentry 'Install' {
set background_color=black
linux /ubuntu-installer/ppc64el/linux auto=true priority=critical
url=http:///preseed/preseed.ppc64el --- quiet
initrd /ubuntu-installer/ppc64el/initrd.gz
}
-- preseed example --
You can use late-commands in your preseed file to install the PPA kernel like:
# Install kernel from PPA
d-i preseed/late_command string in-target add-apt-repository -y
ppa:ubuntu-power-triage/lp1770003
d-i preseed/late_command string in-target apt update
d-i preseed/late_command string in-target apt install -y

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
That is because the package I provided has the same version number as
the -proposed package, my bad, I should have accounted for -proposed
version. I will bump the version an update the package in the PPA.

I have this kernel built in a PPA: ppa:ubuntu-power-triage/lp1770003. This
kernel needs to be tested on the platform (bug does not say if this was found
in P8 or P9) where the issue was reported, and will also need to be tested on
Cavium (ARM64) to make sure there are no regressions.

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
Hi Joseph,
The original patchset just included 4 patches, they are:
d8630bb scsi: qla2xxx: Serialize session deletion by using work_lock
1ae634e scsi: qla2xxx: Serialize session free in qlt_free_session_done
9cd883f scsi: qla2xxx: Fix session cleanup for N2N
eaf75d1 scsi: qla2xxx: Fix double free bug after firmware timeout
The other three patches came as a requirement to backport these 4
patches.
On top of it, the commit id d8630bb95f46 had a regression which would
require the last patch:
1c6cacf scsi: qla2xxx: Fixup locking for session deletion

[Kernel-packages] [Bug 1770003] Re: qla2xxx: Fix page fault at kmem_cache_alloc_node()
If there are too many required patches, a bug fix would not pass the SRU
requirements[1]. The SRU process requires the least amount of changes
to implement the fix.
How did you go about identifying all of the required commits in the bug
description? Is that the minimum number of commits required to fix the
bug? Is it possible to "Reverse" bisect down to a fewer number of
commits?
Is there a specific commit that you know of that introduced this bug in
Bionic? One other option could be to find the offending commit and
revert it.
