zfs-linux (0.6.5.6-0ubuntu10) xenial; urgency=medium
* Sync with relevant upstream fixes (LP: #1594871)
- Fix user namespaces uid/gid mapping
As described in torvalds/linux@5f3a4a2 the &init_user_ns, and
not the current user_ns, should be passed to posix_acl_from_xattr()
and posix_acl_to_xattr(). Conveniently the init_user_ns is
available through the init credential (kcred).
(upstream commit 874bd959f4f15b3d4b007160ee7ad3f4111dd341)
ZFS #4177
- Fix ZPL miswrite of default POSIX ACL
Commit 4967a3e introduced a typo that caused the ZPL to store the
intended default ACL as an access ACL. Due to caching this problem
may not become visible until the filesystem is remounted or the inode
is evicted from the cache. Fix the typo.
(upstream commit 98f03691a4c08f38ca4538c468e9523f8e6b24be)
ZFS #4520
- Create unique partition labels
When partitioning a device a name may be specified for each partition.
Internally zfs doesn't use this partition name for anything so it
has always just been set to "zfs".
However this isn't optimal because udev will create symlinks using
this name in /dev/disk/by-partlabel/. If the name isn't unique
then all the links cannot be created.
Therefore a random 64-bit value has been added to the partition
label, i.e "zfs-1234567890abcdef". Additional information could
be encoded here but since partitions may be reused that might
result in confusion and it was decided against.
(upstream commit fbffa53a5cdb9b796de5afc9be8c1f79619253d4)
ZFS #4517
- Fix inverted logic on none elevator comparison
Commit d1d7e2689db9e03f1 ("cstyle: Resolve C style issues") inverted
the logic on the none elevator comparison. Fix this and make it
cstyle warning clean.
(upstream commit 60a4ea3f948f1596b92b666fc7dd21202544edbb)
ZFS #4507
- Remove wrong ASSERT in annotate_ecksum
When using large blocks like 1M, there will be more than UINT16_MAX
qwords in one block, so this ASSERT would go off. Also, it is possible
for the histogram to overflow. We cap them to UINT16_MAX to prevent this.
(upstream commit 21ea9460fa880bb072a9ca9d845aef740f9d3af6)
ZFS #4257
- Fix 'zpool import' blkid device names
When importing a pool using the blkid cache only the device
node path was added to the list of known paths for a device.
This results in 'zpool import' always using the sdX names
in preference to the 'path' name stored in the label.
To fix the issue the blkid import path has been updated to
add both the 'path', 'devid', and 'devname' names from the
label to the known paths. A sanity check is done to ensure
these paths do refer to the same device identified by blkid.
(upstream commit c9ca152fd1de1b0fd959e772b9a25d14a891952b)
ZFS #4523, #3043
- Use udev for partition detection
When ZFS partitions a block device it must wait for udev to create
both a device node and all the device symlinks. This process takes
a variable length of time and depends on factors such how many links
must be created, the complexity of the rules, etc. Complicating
the situation further it is not uncommon for udev to create and
then remove a link multiple times while processing the udev rules.
In order to address this the zpool_label_disk_wait() function
has been updated to use libudev. Until the registered system
device acknowledges that it in fully initialized the function
will wait. Once fully initialized all device links are checked
and allowed to settle for 50ms. This makes it far more likely
that all the device nodes will exist when the kernel modules
need to open them.
For systems without libudev an alternate zpool_label_disk_wait()
was updated to include a settle time. In addition, the kernel
modules were updated to include retry logic for this ENOENT case.
Due to the improved checks in the utilities it is unlikely this
logic will be invoked. However, if the rare event it is needed
it will prevent a failure.

* Fix ztest truncated cache file (LP: #1587686)
Commit efc412b updated spa_config_write() for Linux 4.2 kernels to
truncate and overwrite rather than rename the cache file. This is
the correct fix but it should have only been applied for the kernel
build. In user space rename(2) is needed because ztest depends on
the cache file.
