  - Config.in: fixed Config.in dependences
  - zfs.hash: proper zfs.hash format
  - zfs.mk: added cpe for openzfs
  - zfs.mk: uclibc patch merged into upstream
  - zfs.mk: removed futile comments as "zfs needs"
  - zfs.mk: added comments about the kernel dependence
  - zfs.mk: removed autotools default arguments values
  - zfs.mk: added optional PAM dependence
  - zfs.mk: replaced inline conditionals by full explained blocks
  - zfs.mk: added comments about optionals systemd and sysv

[Buildroot] [PATCH v3] package/zfs: new package

Jos? Luis, All,

I did a few substancial changes:

  - fix test case on how to use a pre-built toolchain
  - reorder the test case config
  - add test case with glibc
  - drop superflous test timeout override
  - only select libtirpc when C library lacks native RPC
  - drop unused ZFS_MODULES variable
  - drop ZFS_CPE_ID_PREFIX and ZFS_AUTORECONF_OPTS which are defaults
  - drop NLS options, already set in a generic manner
  - drop incomplete/improper sysvinit support
  - some cosmetics

Applied to master with the above changes, thanks.

Regards,
Yann E. MORIN.

The test_zfs doesn't build in our gitlab CI:

https://gitlab.com/kubu93/buildroot/-/jobs/1522848483

zfs use the host compiler to check if it can build zfs modules for the target

checking kernel source directory...

checking kernel build directory...

checking whether modules can be built... no

The check pass if a newer host gcc is used (gcc 10.3 here).

Can you have a look ?

Re: [Buildroot] [PATCH v3] package/zfs: new package

[José Luis Salvador Rufo]

[-- Attachment #1.1: Type: text/plain, Size: 7737 bytes --]

Hello Romain,

I added Philippe Serbruyns to CC (from another related thread).

I'm on it. Currently we have two main issues with ZFS:

- AIO uClibc support for zfs 2.1.X and beyond:

This is the reason I didn't send the `zfs 2.1.x bump version` yet.

This commit added AIO in order to improve the speed importing volumes
parallely:
https://github.com/openzfs/zfs/commit/e50b5217e7a85f1466edf88d5f3ea5aed0c2fd22

But uClibc doesn't support `#include <aio.h>`. So I need to only import
this library when it is not uClibc. I don't figure out yet how (attached a
`poc.patch` for ZFS that does not work).

I'm trying to create a proper patch for upstream.



- Cross-platform-compilations and the `empty module` test:

This issue is very old, and everything is about environments and
cross-platform-compilations. The problem comes from here:
https://github.com/openzfs/zfs/blob/master/config/kernel.m4#L598

In this test, the `make` (modules) is from the host because (I think)
somewhere someone unset all environments. Some people include `export PATH`
in order to execute the `make` from the cross-compilation environment. I am
still thinking about a proper patch for upstream.

Here is my `build.log` from the referred `make`:

make[2]: Entering directory
'/home/jlsalvador/src/buildroot-rpi4-tmp/build/linux-custom'


  ERROR: Kernel configuration is invalid.

         include/generated/autoconf.h or include/config/auto.conf are

make[2]: Leaving directory

The `include/config/auto.conf` file exists:

$ file
/home/jlsalvador/src/buildroot-rpi4-tmp/build/linux-custom/include/config/auto.conf
/home/jlsalvador/src/buildroot-rpi4-tmp/build/linux-custom/include/config/auto.conf:
Linux make config build file, ASCII text


But because the `make` is from a x86, and the final platform is a Arm64,
the LINUX config is incorrect.

As you already saw, I need to figure out how to use the `make` from the
cross-compilation path instead of the host path for this test.


This is the current status. I'm trying to fix the second issue today. Any
help is more than welcome.

Greetings.
