  [18.04][config] regression: nvme and nvme_core couldn't be built as
  modules starting 4.15-rc2

Status in linux package in Ubuntu:

Status in linux source package in Bionic:
  Fix Released

Bug description:
  Some regression was introduced into NVME-related kernel configuration
  by 32c662c58a9b9 into 4.15-rc2, which was pulled later into ubuntu-
  bionic.git

  In result, "nvme" and "nvme_core" drivers are built into the kernel,
  we can't build them as modules. It caused incompatibility of NMVe-OF
  target and initiator modules (nvmet, nvme-rdma) installed by Mellanox
  OFED with the inbox "nvme" driver.

  Root cause analysis.

  In the drivers/lightnvm/Kconfig file - kernel configuration for the 
OpenChannel SSDs (lightnvm) we have:
   
  menuconfig NVM
  bool "Open-Channel SSD target support"
  depends on BLOCK && HAS_DMA && PCI
  select BLK_DEV_NVME
  help
Say Y here to get to enable Open-channel SSDs.
  ...

  
  It means that BLK_DEV_NVME is selected to "y" when  NVM (CONFIG_NVM) is 
selected.
  NVM parameter is 2 state (on / off, i.e. "y" or "no"), it couldn't be built 
as a module.
  So that it triggers the change of BLK_DEV_NAME=y and NVME_CORE=y

  lightnvm: include NVM Express driver if OCSSD is selected for
  build

  Because NVM needs BLK_DEV_NVME, select it automatically if we mark NVM
  in config file before building kernel.  Also append PCI to depends as
  select doesn't automatically add dependencies.

[Kernel-packages] [Bug 1759893] Re: [18.04][config] regression: nvme and nvme_core couldn't be built as modules starting 4.15-rc2

2019-02-14 Thread Brad Figg

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!

[Kernel-packages] [Bug 1759893] Re: [18.04][config] regression: nvme and nvme_core couldn't be built as modules starting 4.15-rc2

2019-02-14 Thread Brad Figg

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!

Title:
  [18.04][config] regression: nvme and nvme_core couldn't be built as
  modules starting 4.15-rc2

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released

Bug description:
  Some regression was introduced into NVME-related kernel configuration
  by 32c662c58a9b9 into 4.15-rc2, which was pulled later into ubuntu-
  bionic.git

  In result, "nvme" and "nvme_core" drivers are built into the kernel,
  we can't build them as modules. It caused incompatibility of NMVe-OF
  target and initiator modules (nvmet, nvme-rdma) installed by Mellanox
  OFED with the inbox "nvme" driver.

  Root cause analysis.

  In the drivers/lightnvm/Kconfig file - kernel configuration for the 
OpenChannel SSDs (lightnvm) we have:
   
  menuconfig NVM
  bool "Open-Channel SSD target support"
  depends on BLOCK && HAS_DMA && PCI
  select BLK_DEV_NVME
  help
Say Y here to get to enable Open-channel SSDs.
  ...

  
  It means that BLK_DEV_NVME is selected to "y" when  NVM (CONFIG_NVM) is 
selected.
  NVM parameter is 2 state (on / off, i.e. "y" or "no"), it couldn't be built 
as a module.
  So that it triggers the change of BLK_DEV_NAME=y and NVME_CORE=y

  $ git blame drivers/lightnvm/Kconfig

  Author: Rakesh Pandit 
  Date:   Fri Oct 13 14:45:55 2017 +0200

  lightnvm: include NVM Express driver if OCSSD is selected for
  build

  Because NVM needs BLK_DEV_NVME, select it automatically if we mark NVM
  in config file before building kernel.  Also append PCI to depends as
  select doesn't automatically add dependencies.

[Kernel-packages] [Bug 1759893] Re: [18.04][config] regression: nvme and nvme_core couldn't be built as modules starting 4.15-rc2

2018-04-05 Thread Yurii Shestakov

Hi Seth,

No, I've not reported this issue to the upstream yet. I guess somebody
from our company, who works on NVMe-OF related code in the kernel,
should do this.

To be honest I'm not sure that my fix is technically correct and takes
into account all dependencies. So that I'm fine with reverting of
32c662c58a9b9d0c99e713a14ca323a9a91c73a0.

Thank you.

[Kernel-packages] [Bug 1759893] Re: [18.04][config] regression: nvme and nvme_core couldn't be built as modules starting 4.15-rc2

2018-04-05 Thread Seth Forshee

Have you reported this upstream?

It does look to me that this dependency is working the wrong way, that
CONFIG_BLK_DEV_NVME depends on CONFIG_NVME and not the other way around.
The driver enabled by CONFIG_BLK_DEV_NVME has no entry points other than
the struct pci_driver callbacks, but it does call into the code enabled
by CONFIG_NVME.

I'm not convinced that yours is the correct fix though. I suspect that
BLK_DEV_NVME should have a "depends on NVM" or "select NVM" instead.
What I will do though is revert 32c662c58a9b9d0c99e713a14ca323a9a91c73a0
and change BLK_DEV_NVME back to =m. You should probably follow up
upstream to get a fix in place there.

  Some regression was introduced into NVME-related kernel configuration

  In result, "nvme" and "nvme_core" drivers are built into the kernel,

2018-03-30 Thread Yurii Shestakov

>From the KConfig tutorial:
https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt

- reverse dependencies: "select"  ["if" ]
  While normal dependencies reduce the upper limit of a symbol (see
  below), reverse dependencies can be used to force a lower limit of
  another symbol. The value of the current menu symbol is used as the
  minimal value  can be set to. If  is selected multiple
  times, the limit is set to the largest selection.
  Reverse dependencies can only be used with boolean or tristate
  symbols.
  Note:
*select should be used with care.* select will force
a symbol to a value without visiting the dependencies.
By abusing select you are able to select a symbol FOO even
if FOO depends on BAR that is not set.
In general use select only for non-visible symbols
(no prompts anywhere) and for symbols with no dependencies.
That will limit the usefulness but on the other hand avoid
the illegal configurations all over.

** Description changed:

  Some regression was introduced into NVME-related kernel configuration by
  32c662c58a9b9 into 4.15-rc2, which was pulled later into ubuntu-
  bionic.git
  
  In result, "nvme" and "nvme_core" drivers are built into the kernel, we
  can't build them as modules. It caused incompatibility of NMVe-OF target
  and initiator modules (nvmet, nvme-rdma) installed by Mellanox OFED with
  the inbox "nvme" driver.
  
  Root cause analysis.
  
  In the drivers/lightnvm/Kconfig file - kernel configuration for the 
OpenChannel SSDs (lightnvm) we have:
   
  menuconfig NVM
  bool "Open-Channel SSD target support"
  depends on BLOCK && HAS_DMA && PCI
  select BLK_DEV_NVME
  help
Say Y here to get to enable Open-channel SSDs.
  ...
  
  
  It means that BLK_DEV_NVME is selected to "y" when  NVM (CONFIG_NVM) is 
selected.
  NVM parameter is 2 state (on / off, i.e. "y" or "no"), it couldn't be built 
as a module.
  So that it triggers the change of BLK_DEV_NAME=y and NVME_CORE=y

  lightnvm: include NVM Express driver if OCSSD is selected for build
  
  Because NVM needs BLK_DEV_NVME, select it automatically if we mark NVM
  in config file before building kernel.  Also append PCI to depends as
  select doesn't automatically add dependencies.
