zfs-linux (0.6.5.6-0ubuntu21) xenial; urgency=medium
* Add ZFS 0.7.0 compat fix for zvol_id (LP: #1763067)
The BLKZNAME ioctl msg size has changed in ZFS 0.7.0 so
add forwards compat handling for this ioctl by retrying
with this newer msg size if the first call fails

Title:
zvol_id throws ioctl_get_msg failed:Inappropriate ioctl for device
Status in zfs-linux package in Ubuntu:
Invalid
Status in zfs-linux source package in Xenial:
Fix Released
Status in zfs-linux source package in Artful:
Fix Released
Bug description:
== SRU Justification [XENIAL][ARTFUL] ==
Symlinks in /dev/zvol are not because /lib/udev/zvol_id exits with
ioctl_get_msg failed:Inappropriate ioctl for device. The core reason
is that the BLKZNAME with non-HWE userspace zfsutils is 1 char
different is size than the HWE kernel drivers.
== Fix ==
Change the userland zvol_id tool to use the V0.6.x ZFS_MAXNAMELEN size
and if that fails with ENOTTY retry with the V0.07.0 ZFS_MAXNAMELEN
size as a fallback compatibility call.
== Regression Potential ==
Very small, this changes zvol_id and keeps the original functionality
as well as adding V7 ZFS functionality as a fallback. At worse,
zvol_id will not work, but that's the same as the current broken
state.
== Testing ==
create a volume, e.g. zfs create -V 8M ${POOL}/testvol
run /lib/udev/zvol_id on /dev/zd0 on Xenial with a 4.15 Xenial HWE
kernel. Without the fix one gets an ENOTTY errno failure. With the
fix zvol_id returns the zvol id and symlinks in /dev/zvol work.
---
Symlinks in /dev/zvol are not created because /lib/udev/zvol_id
crashes with ioctl_get_msg failed:Inappropriate ioctl for device.
Description: Ubuntu 16.04.4 LTS

without error.
