From day one the various ZFS libraries should have been placed in their
own sub-packages. Primarily this allows for multiple major versions of
the libraries to be concurrently installed. It also facilitates a
smaller build environment by minimizing the required dependencies.
The specific changes required to split the libraries from the utilities
are as follows:
* libzpool2, libnvpair1, libuutil1, and libzfs2 packages were added
and contain the versioned shared libraries. The Fedora packaging
guidelines discourage providing static libraries so they are not
included in the packages.
http://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libraries
* The zfs-devel package was renamed libzfs2-devel and the new package
obsoletes the old zfs-devel package. This package includes all
the required headers for the libzpool2, libnvpair1, libuutil1, and
libzfs2 libraries and their respective unversioned shared libraries.
This package should eventually be split in to individual lib*-devel
packages but it will still take some work to cleanly separate them.
Therefore the libzfs2-devel package provides the expected lib*-devel
packages so the all proper dependencies can still be created.
http://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages
* Moved '/sbin/ldconfig' execution from the zfs packge to each of the
new library packages as described by the packaging guidelines.
http://fedoraproject.org/wiki/Packaging:Guidelines#Shared_Libraries
* The /usr/share/doc/ files were moved in to the libzfs2-devel package.
* Updated config/deb.am to be aware of the packaging changes. This
ensures that 'deb-utils' make target converts all the resulting
packages generated by the 'rpm-utils' target.

For small objects the Linux slab allocator has several advantages
over its counterpart in the SPL. These include:
1) It is more memory-efficient and packs objects more tightly.
2) It is continually tuned to maximize performance.
Therefore it makes sense to layer the SPLs slab allocator on top
of the Linux slab allocator. This allows us to leverage the
advantages above while preserving the Illumos semantics we depend
on. However, there are some things we need to be careful of:
1) The Linux slab allocator was never designed to work well with
large objects. Because the SPL slab must still handle this use
case a cut off limit was added to transition from Linux slab
backed objects to kmem or vmem backed slabs.
spl_kmem_cache_slab_limit - Objects less than or equal to this
size in bytes will be backed by the Linux slab. By default
this value is zero which disables the Linux slab functionality.
Reasonable values for this cut off limit are in the range of
4096-16386 bytes.
spl_kmem_cache_kmem_limit - Objects less than or equal to this
size in bytes will be backed by a kmem slab. Objects over this
size will be vmem backed instead. This value defaults to
1/8 a page, or 512 bytes on an x86_64 architecture.
2) Be aware that using the Linux slab may inadvertently introduce
new deadlocks. Care has been taken previously to ensure that
all allocations which occur in the write path use GFP_NOIO.
However, there may be internal allocations performed in the
Linux slab which do not honor these flags. If this is the case
a deadlock may occur.
The path forward is definitely to start relying on the Linux slab.
But for that to happen we need to start building confidence that
there aren't any unexpected surprises lurking for us. And ideally
need to move completely away from using the SPLs slab for large
memory allocations. This patch is a first step.
NOTES:
1) The KMC_NOMAGAZINE flag was leveraged to support the Linux slab
backed caches but it is not supported for kmem/vmem backed caches.
2) Regardless of the spl_kmem_cache_*_limit settings a cache may
be explicitly set to a given type by passed the KMC_KMEM,
KMC_VMEM, or KMC_SLAB flags during cache creation.
3) The constructors, destructors, and reclaim callbacks are all
functional and will be called regardless of the cache type.
4) KMC_SLAB caches will not appear in /proc/spl/kmem/slab due to
the issues involved in presenting correct object accounting.
Instead they will appear in /proc/slabinfo under the same names.
5) Several kmem SPLAT tests needed to be fixed because they relied
incorrectly on internal kmem slab accounting. With the updated
test cases all the SPLAT tests pass as expected.
6) An autoconf test was added to ensure that the __GFP_COMP flag
was correctly added to the default flags used when allocating
a slab. This is required to ensure all pages in higher order
slabs are properly refcounted, see ae16ed9.
7) When using the SLUB allocator there is no need to attempt to
set the __GFP_COMP flag. This has been the default behavior
for the SLUB since Linux 2.6.25.
8) When using the SLUB it may be desirable to set the slub_nomerge
kernel parameter to prevent caches from being merged.

zed supports a '-M' cmdline opt to lock all pages in memory via
mlockall(). The _POSIX_MEMLOCK define is checked to determine whether
this function is supported. The current test assumes mlockall()
is supported if _POSIX_MEMLOCK is non-zero. However, this test is
insufficient according to mlock(2) and sysconf(3). If _POSIX_MEMLOCK
is -1, mlockall() is not supported; but if _POSIX_MEMLOCK is 0,
availability must be checked at runtime.
This commit adds an autoconf check for mlockall() to user.m4. The zed
code block for mlockall() is now guarded with a test for HAVE_MLOCKALL.
If defined, mlockall() will be called and its runtime availability

GCC >+ 4.8's aggressive loop optimization breaks some of the iterators
over the dn_blkptr[] pseudo-array in dnode_phys. Since dn_blkptr[] is
defined as a single-element array, GCC believes an iterator can only
access index 0 and will unroll the loop into a single iteration.
One way to resolve the issue would be to cast the array to a pointer
and fix all the iterators that might break. The only loop where it
is known to cause a problem is this loop in dmu_objset_write_ready():
for (i = 0; i < dnp->dn_nblkptr; i++)
bp->blk_fill += dnp->dn_blkptr[i].blk_fill;
In the common case where dn_nblkptr is 3, the loop is only executed a
single time and "i" is equal to 1 following the loop.
The specific breakage caused by this problem is that the blk_fill of
root block pointers wouldn't be set properly when more than one blkptr
is in use (when no indrect blocks are needed).
The simple reproducing sequence is:
zpool create tank /tank.img
zdb -ddddd tank 0
Notice that "fill=31", however, there are two L0 indirect blocks with
"F=31" and "F=5". The fill count should be 36 rather than 31. This
problem causes an assert to be hit in a simple "zdb tank" when built
with --enable-debug.
However, this approach was not taken because we need to be absolutely
sure we catch all instances of this unwanted optimization. Therefore,
the build system has been updated to detect if GCC supports the
aggressive loop optimization. If it does the optimization will be
explicitly disabled using the -fno-aggressive-loop-optimization option.

Four new dataset properties have been added to support SELinux. They
are 'context', 'fscontext', 'defcontext' and 'rootcontext' which map
directly to the context options described in mount(8). When one of
these properties is set to something other than 'none'. That string
will be passed verbatim as a mount option for the given context when
the filesystem is mounted.
For example, if you wanted the rootcontext for a filesystem to be set
to 'system_u:object_r:fs_t' you would set the property as follows:
$ zfs set rootcontext="system_u:object_r:fs_t" storage-pool/media
This will ensure the filesystem is automatically mounted with that
rootcontext. It is equivalent to manually specifying the rootcontext
with the -o option like this:
$ zfs mount -o rootcontext=system_u:object_r:fs_t storage-pool/media
By default all four contexts are set to 'none'. Further information
on SELinux contexts is detailed in mount(8) and selinux(8) man pages.

Needed for Illumos #3582. This interface is supposed to support
a variable-resolution timeout with nanosecond granularity. This
implementation rounds up to microsecond resolution, as nanosecond-
precision timing is rarely needed for real-world performance
tuning and may incur unnecessary busy-waiting. usleep_range() is
used if available, otherwise udelay() or msleep() are used
depending on the length of the delay interval.
Add flags from sys/callo.h as these are used to control the behavior of
cv_timedwait_hires(). Specifically,
CALLOUT_FLAG_ABSOLUTE
Normally, the expiration passed to the timeout API functions is
an expiration interval. If this flag is specified, then it is
interpreted as the expiration time itself.
CALLOUT_FLAG_ROUNDUP
Roundup the expiration time to the next resolution boundary. If this
flag is not specified, the expiration time is rounded down.

This change adds support for Posix ACLs by storing them as an xattr
which is common practice for many Linux file systems. Since the
Posix ACL is stored as an xattr it will not overwrite any existing
ZFS/NFSv4 ACLs which may have been set. The Posix ACL will also
be non-functional on other platforms although it may be visible
as an xattr if that platform understands SA based xattrs.
By default Posix ACLs are disabled but they may be enabled with
the new 'aclmode=noacl|posixacl' property. Set the property to
'posixacl' to enable them. If ZFS/NFSv4 ACL support is ever added
an appropriate acltype will be added.
This change passes the POSIX Test Suite cleanly with the exception
of xacl/00.t test 45 which is incorrect for Linux (Ext4 fails too).

1. Make a 64MB file, which is the minimum size ZFS permits.
2. Make 4 fake uberblock entries to make libblkid's check succeed.
3. Return 0 upon success to make autotools use the success case.
4. Include stdlib.h to avoid implicit declration of free().
5. Check for "zfs_member", not "zfs"
6. Make --with-blkid disable autotools check (avoids Gentoo sandbox violation)
7. Pass '-lblkid' correctly using LIBS not LDFLAGS.
Second, we change the libblkid support to scan for "zfs_member", not
"zfs".

Commit torvalds/linux@2233f31aad
replaced ->readdir() with ->iterate() in struct file_operations.
All filesystems must now use the new ->iterate method.
To handle this the code was reworked to use the new ->iterate
interface. Care was taken to keep the majority of changes
confined to the ZPL layer which is already Linux specific.
However, minor changes were required to the common zfs_readdir()
function.
Compatibility with older kernels was accomplished by adding
versions of the trivial dir_emit* helper functions. Also the
various *_readdir() functions were reworked in to wrappers
which create a dir_context structure to pass to the new
*_iterate() functions.
Unfortunately, the new dir_emit* functions prevent us from
passing a private pointer to the filldir function. The xattr
directory code leveraged this ability through zfs_readdir()
to generate the list of xattr names. Since we can no longer
use zfs_readdir() a simplified zpl_xattr_readdir() function
was added to perform the same task.

The iterate_supers_type() function which was introduced in the
3.0 kernel was supposed to provide a safe way to call an arbitrary
function on all super blocks of a specific type. Unfortunately,
because a list_head was used a bug was introduced which made it
possible for iterate_supers_type() to get stuck spinning on a
super block which was just deactivated.
This can occur because when the list head is removed from the
fs_supers list it is reinitialized to point to itself. If the
iterate_supers_type() function happened to be processing the
removed list_head it will get stuck spinning on that list_head.
The bug was fixed in the 3.3 kernel by converting the list_head
to an hlist_node. However, to resolve the issue for existing
3.0 - 3.2 kernels we detect when a list_head is used. Then to
prevent the spinning from occurring the .next pointer is set to
the fs_supers list_head which ensures the iterate_supers_type()
function will always terminate.

Issue #111
When building from an arbitrary commit in the git tree it's useful
for the resulting packages to be uniquely identifiable. Therefore,
the build system has been updated to detect if your compiling in
git tree.
If you are building in a git tree, and there are commits after the
last annotated tag. Then the <id>-<hash> component of 'git describe'
will be used to overwrite the 'Release:' field in the META file.
The only tricky part is that to ensure the 'make dist' tarball is
built using the correct release. A dist-hook was added to the top
level make file to rewrite the META file using the correct release.
