Bug description:
  [Impact]

   * Xenial with HWE kernel (matching new relesaes) and qemu without cloud
 archive (not matching new releases) could trigger hypercalls that are 
 not supported in xenials-qemu.

   * There is no "real" case other than kvm tests yet to trigger it yet, but 
 it is an easy and well contained fix, so we might fix proactively.

  [Test Case]

1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1 
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v

  [Regression Potential]

   * The changes are all upstream since a long time now (lowering the risk 
 of silly mistakes)
   * The changes are isolated to ppc, so in the worst case only this arch 
 should regress.
   * We implement new hcalls, so if anything there might be a regression if 
 software expected them to fail, but now breaks by them working (don't 
 think so given the nature of these hcalls).

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2018-02-08 Thread Brian Murray 
Hello Po-Hsu, or anyone else affected,

Accepted qemu into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/qemu/1:2.5+dfsg-
5ubuntu10.21 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Changed in: qemu (Ubuntu Xenial)
   Status: In Progress => Fix Committed

  [Impact]

   * Xenial with HWE kernel (matching new relesaes) and qemu without cloud
 archive (not matching new releases) could trigger hypercalls that are 
 not supported in xenials-qemu.

   * There is no "real" case other than kvm tests yet to trigger it yet, but 
 it is an easy and well contained fix, so we might fix proactively.

  [Test Case]

1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1 
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v

  [Regression Potential]

   * The changes are all upstream since a long time now (lowering the risk 
 of silly mistakes)
   * The changes are isolated to ppc, so in the worst case only this arch 
 should regress.
   * We implement new hcalls, so if anything there might be a regression if 
 software expected them to fail, but now breaks by them working (don't 
 think so given the nature of these hcalls).

Also passed all regression tests on ppc without a hickup.
Other than waiting for the security update to pass we are ready.

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2018-02-01 Thread ChristianEhrhardt 
Current is 1:2.5+dfsg-5ubuntu10.16, and while there is a security update
for 1:2.5+dfsg-5ubuntu10.17 incoming we can - as discussed - test from a
ppa.

To stay ahead of the soon to be expected 1:2.5+dfsg-5ubuntu10.17 I'll
call mine 1:2.5+dfsg-5ubuntu10.18~ppa1 (actually skipping 17 for now so
you stay ahead in testing).

@Yasmins - actually your email address to be correctly referred to in
headers/changelog would be nice - so far I go with (IBM) as an address
:-)

The proposed fix is now building in [1] and should be available in ~1h.
@Po-Hsu and Yasmins: please check this ppa build with your tests. If they are 
good and my regression tests pass as well we are as prepared as we can be to 
fix this when the security update is complete.

2018-01-31 Thread Yasmin Beatriz Alves da Silva 
One minor detail I should mention is that you're going to see 3 patches
on the file instead of 2. That is because h_page_init hypercall depends
on a function `is_ram_address` that didn't exist in v2.5. This patch has
been backported as well.

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2018-01-25 Thread ChristianEhrhardt 
Hi Yasmins,
you can either attach the patches as files here on the LP bug or point me to a 
git branch of yours that I can reach.
Unless you want to do the related packaging work as well that is all I need.
I can easily do the wrap up of the patches into the packaging for you.

TL;DR - I'm not going to block you by "restrictive workflow processes",
get the patches to me in any way and I'll make it work :-)

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2018-01-25 Thread ChristianEhrhardt 
The patch seems easy enough, only the second has some very minor noise when 
applying.
Let me know if I should do the backport or if you want to provide patches 
against 2.5 (patches against 2.5 as of the qemu git is fine).

In terms of SRU scheduling I think prio is low, but it is easy enough and seems 
right to do so.
But OTOH several qemu security updates are in flight.

My suggestion would be to:
1. backport (or get it from you)
2. provide a build in a ppa to have the solution verified
3. once spectre fixes have settled upload on top of that

Are you ok with that - and please choose what you prefer on #1

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2017-10-16 Thread Po-Hsu Lin 
Steps to reproduce:
1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1 
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v

>From here you will see it's using the elf file from kvm-unit-tests/powerpc and 
>failed with 3 tests:
 - spapr_hcall
 - emulator (bug 1723914)
 - sprs (1723904)

To run it with a newer qemu built from source:
1. wget http://download.qemu-project.org/qemu-2.10.0.tar.xz
2. tar -xf qemu-2.10.0.tar.xz
3. cd qemu-2.10.0
4. ./configure; make
5. cd ~/kvm-unit-tests
6. sudo su
7. export QEMU=/home/ubuntu/qemu-2.10.0/ppc64-softmmu/qemu-system-ppc64
8. ./run_test -v

2017-10-16 Thread ChristianEhrhardt 
Catched Po-Hsu on IRC.

He will outline the steps to get the test elf image and then we should
mirror to IBM so they can check which ppc changes would be needed. Based
on knowing that we can then decide to SRU or not.

[Kernel-packages] [Bug 1712803] Re: spapr_hcall from ubuntu_kvm_unit_test failed on ppc64el with Z-hwe kernel

2017-10-16 Thread ChristianEhrhardt 
Hi Po-Hsu,
what do you mean by "introduced by the old qemu version"?
I assume you are testing new kernels by the kernel-da-key tag?
So do you mean "the new (maybe HWE) kernel fails this test on xenial" - and 
your assumption is that it triggers there because qemu doesn't have the right 
fixes to be able to handle it?
If so we should mirror this bug to IBM so they can assist in picking the right 
ppc patches needed.

Bug description:
  kernel: 4.10.0-33.37~16.04.1

  I think this issue was introduced by the old qemu version (similar
  issue was spotted on Xenial before), will need to investigate this
  further.

  
  qemu-system-ppc64 -machine pseries,accel=kvm -bios powerpc/boot_rom.bin 
-display none -serial stdio -kernel powerpc/spapr_hcall.elf -smp 1
