Bug#934282: zfs-dkms: fails to install for 5.2.0-2-amd64 due to GPL-only symbol 'alternatives_patched'

2019-08-09 Thread Craig Sanders 
I tested this on one of my ZFS testing VMs ('ztest') and can confirm that
zfs-dkms 0.8.1 compiles against 5.2.0-2-amd64 when the patch is applied to
/var/lib/dkms/zfs/0.8.1/source/include/linux/simd_x86.h

ztest:~# dkms status
zfs, 0.8.1, 4.19.0-3-amd64, x86_64: installed
zfs, 0.8.1, 4.19.0-5-amd64, x86_64: installed
zfs, 0.8.1, 5.2.0-2-amd64, x86_64: installed


The VM reboots successfuly and the zfs pool is working normally:

ztest:~# uname -a

Bug#934282: zfs-dkms: fails to install for 5.2.0-2-amd64 due to GPL-only symbol 'alternatives_patched'

2019-08-08 Thread Harry Sintonen 
Package: zfs-dkms
Version: 0.8.1-3
Severity: important
Tags: patch

Dear Maintainer,

The module fails to build against 5.2.0-2-amd64 due to use of GPL-only symbol:
"
  Building modules, stage 2.
  MODPOST 8 modules
FATAL: modpost: GPL-incompatible module zfs.ko uses GPL-only symbol 
'alternatives_patched'
make[6]: *** 
[/usr/src/linux-headers-5.2.0-2-common/scripts/Makefile.modpost:91: __modpost] 
Error 1
"

Apparently this is due to the kernel being built with CONFIG_X86_DEBUG_FPU=Y 
which results
in pulling the symbol. Patch fixing this issue is here:
