Additionally took the new crash version and installed it on s390x. I can
still load dumps produced before and also dumps done after updating
crash (just in case crash is in any way used to produce the dumps, which
I do not think is true).

I also verified that the current version fails to load the kdump kernel
with linux-azure (4.11.0-1009.9) and that the version in -proposed fixes
the problem. The version in -proposed also works as expected with the
4.4 xenial kernel running in azure and in kvm.

Hello Joshua, or anyone else affected,

Accepted crash into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/crash/7.1.4-1ubuntu4.2
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, details of your
testing will help us make a better decision.

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

** Description changed:

  [Impact]
  
  Currently it's not possible to use the kdump functionality in xenial
- when running the linux-azure kernel. The problem is actually caused but
+ when running the linux-azure kernel. The problem is actually caused by
  several factors:
  
  1. kexec fails to parse /proc/kcore and thus fails to load the crash
  kernel. That's similar to bug #1713940 and it's related to 4.10+
  kernels.
  
  2. When the crash kernel boots, a bug in KASLR causes it to crash in a
  very early stage. For the user, it seems the system just rebooted after
  the crash.
  
  3. Currently in azure, crashkernel=128G is not enough to boot and run
  the dump procedure with 4.11+ kernels. That value needs to be increased
  in order to kdump to succeed.
  
  4. After the vmcore is dumped, the current version of crash in xenial is
  not able to parse it. All the necessary fixes are already upstream and
  can be backported.
  
  [Test Case]
  
  1. Install the linux-azure kernel in an azure instance (although it's
  possible to run linux-azure in bare metal or kvm, the KASLR issue only
  is triggered in azure).
  
  2. Follow the instructions in https://help.ubuntu.com/lts/serverguide
  /kernel-crash-dump.html to setup kdump and manually trigger a crash
  using /proc/sysrq-trigger.
  
  The vmcore must be generated and it should be possible to inspect it
  using crash.
  
  [Regression Potential]
  
  Since both kexec-tools and crash are being changed to support 4.10+
  kernels, it's very important that they continue to handle 4.4 kernels
  properly.
  
  The same steps above can be used to test linux-generic for regressions.
  
  [Other Info]
  
  Original description:
  
  --8<--
  Because the linux-azure kernel is based on 4.11, kexec on 16.04 gives the 
following error:
  kdump-tools[1436]: ELF core (kcore) parse failed

I was able to make the xenial version of crash to work with both the
linux-generic and linux-azure kernels applying the following upstream
changes:

Commit: 7e0cb8b516788c7ba1ef9f32556df347ba0da187
Fix for Linux commit 0100301bfdf56a2a370c7157b5ab0fbf9313e1cd, which rewrote 
the X86_64 switch_to() code by embedding the __switch_to() call inside a new 
__switch_to_asm() assembly code ENTRY() function. Without the patch, the 
message "crash: cannot determine thread return address" gets displayed during 
initialization, and the "bt" command shows frame #0 starting at "schedule" 
instead of "__schedule". (ander...@redhat.com)

Fix for the "ps -t" option in 3.17 and later kernels that contain commit 
ccbf62d8a284cf181ac28c8e8407dd077d90dd4b, which changed the

Improvement of the accuracy of the allocated objects count for each kmem_cache

Commit: df08978f31ba39e94b3096804f4e0776373c8b53
Improvement of the "dev -d" option to display I/O statics for disks whose 
device driver uses the blk-mq interface.  Currently "dev -d" always displays 0 
in all fields for the blk-mq disk because blk-mq does not increment/decrement 
request_list.count[2] on I/O creation and I/O completion.  The following values 
are used in blk-mq in such situations:   - I/O creation:   
blk_mq_ctx.rq_dispatched[2]   - I/O completion: blk_mq_ctx.rq_completed[2] So, 
we can get the counter of in-progress I/Os as follows:   in progress I/Os == 
rq_dispatched - rq_completed This patch displays the result of above 
calculation for the disk. It determines whether the device driver uses blk-mq 
if the request_queue.mq_ops is not NULL.  The "DRV" field is displayed as 
"N/A(MQ)" if the value for in-flight in the device driver does not exist for 
blk-mq. (m.miz...@jp.fujitsu.com)

Commit: db552975315fec06a957c937803935d8fbddfd2d
Introduction of a new "bt -v" option that checks the kernel stack of all tasks 
for evidence of stack overflows.  It does so by verifying the thread_info.task 
address, ensuring the thread_info.cpu value is a valid cpu number, and checking 
the end of the stack for the STACK_END_MAGIC value. (ander...@redhat.com)

[Bug 1712867] Re: [Hyper-V] 16.04 kexec-tools doesn't match linux-azure

2017-09-08 Thread Marcelo Cerri 
I was able to properly dump a vmcore with the following steps:

1. kexec-tools patches with:
   - ed15ba1b9977 build_mem_phdrs(): check if p_paddr is invalid
   - 9f62cbfc kexec/arch/i386: Add support for KASLR memory randomization
   - dbb99d938810 kexec-tools/x86: get_kernel_vaddr_and_size off-by-one fix

2. crashkernel increased to 192M

3. linux-azure patched with:
   - da63b6b20077 x86/KASLR: Fix kexec kernel boot crash when KASLR 
randomization fails

4. Forced storvsc instead of ata_piix.

With those changes, I was able to consistently dump vmcore images
without any issues using several types of azure instances.

Besides that the utility crash also needs to be updated. Currently the
xenial version of crash is not able to parse a linux-azure vmcore but
the artful version is.

I'm running some tests with the artful crash utility and the linux-
generic kernel to check if it's viable to bring that version to xenial.

[Bug 1712867] Re: [Hyper-V] 16.04 kexec-tools doesn't match linux-azure

2017-09-01 Thread Marcelo Cerri 
Porting the artful kexec-tools from artful to xenial fixes the kcore
parse failure and doesn't cause any regressions when used with the
regular xenial kernel.

However, although "kdump-config load" doesn't fail anymore, the dump is
not generated when using linux-azure. The artful kexec-tools also
requires kdump-tools to be ported from artful. Because of that, I
backported the necessary fixes into the xenial kexec-tools in order to
keep the same kdump-tools version. The result was the same as using
artful kexec-tools/kdump-tools and the dump wasn't generated when using
linux-azure.

Further investigation is still necessary.
