Remove deduplicated send/receive code Deduplicated send streams (i.e. `zfs send -D` and `zfs receive` of such streams) are deprecated. Deduplicated send streams can be received by first converting them to non-deduplicated with the `zstream redup` command. This commit removes the code for sending and receiving deduplicated send streams. `zfs send -D` will now print a warning, ignore the `-D` flag, and generate a regular (non-deduplicated) send stream. `zfs receive` of a deduplicated send stream will print an error message and fail. The resulting code simplification (especially in the kernel's support for receiving dedup streams) should help enable future performance enhancements. Several new tests are added which leverage `zstream redup`.

Support custom URI schemes for the keylocation property Every platform has their own preferred methods for implementing URI schemes beyond the currently supported file scheme (e.g. 'https' on FreeBSD would likely use libfetch, while Linux distros and illumos would probably use libcurl, etc). It would be helpful if libzfs can be extended to support additional schemes in a simple manner. A table of (scheme, handler_function) pairs is added to libzfs_crypto.c, and the existing functions in libzfs_crypto.c so that when the key format is ZFS_KEYFORMAT_URI, the scheme from the URI string is extracted, and a matching handler it located in the aforementioned table (returning an error if no matching handler is found). The handler function is then invoked to retrieve the key material (in the format specified by the keyformat property) and the key is loaded or the handler can return an error to abort the key loading process.

Multi-modifier protection (MMP) Add multihost=on|off pool property to control MMP. When enabled a new thread writes uberblocks to the last slot in each label, at a set frequency, to indicate to other hosts the pool is actively imported. These uberblocks are the last synced uberblock with an updated timestamp. Property defaults to off. During tryimport, find the "best" uberblock (newest txg and timestamp) repeatedly, checking for change in the found uberblock. Include the results of the activity test in the config returned by tryimport. These results are reported to user in "zpool import". Allow the user to control the period between MMP writes, and the duration of the activity test on import, via a new module parameter zfs_multihost_interval. The period is specified in milliseconds. The activity test duration is calculated from this value, and from the mmp_delay in the "best" uberblock found initially. Add a kstat interface to export statistics about Multiple Modifier Protection (MMP) updates. Include the last synced txg number, the timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV label that received the last MMP update, and the VDEV path.

By default it is set to zero meaning that no MMP statistics are stored. When using ztest to generate activity, for automated tests of the MMP function, some test functions interfere with the test. For example, the pool is exported to run zdb and then imported again. Add a new ztest function, "-M", to alter ztest behavior to prevent this. Add new tests to verify the new functionality.

OpenZFS 7541 - zpool import/tryimport ioctl returns ENOMEM Authored by: Pavel Zakharov <pavel.zakharov@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Dan Kimmel <dan.kimmel@delphix.com> The refresh_config() calls into the kernel with ZFS_IOC_POOL_TRYIMPORT. This ioctl returns the config of the pool in a buffer pre-allocated in userland. The original estimate for the size is too conservative since it doesn't account for the large size of vdev stats that are added to the config before returning. This fix simply increases the size of the buffer passed. This results in a speed up of the zpool import process, and less spam in zfs_dbgmsg.

Add 'zfs rename -u' to rename without remounting Allow to rename file systems without remounting if it is possible. It is possible for file systems with 'mountpoint' property set to 'legacy' or 'none' - we don't have to change mount directory for them. Currently such file systems are unmounted on rename and not even mounted back. This introduces layering violation, as we need to update 'f_mntfromname' field in statfs structure related to mountpoint (for the dataset we are renaming and all its children). In my opinion it is worth it, as it allow to update FreeBSD in even cleaner way - in ZFS-only configuration root file system is ZFS file system with 'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs, we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs), update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs and rename it back to system/rootfs while it is mounted as /. Before it was not possible, because unmounting / was not possible.

mount: use the mount syscall directly Allow zfs datasets to be mounted on Linux without relying on the invocation of an external processes. This is the same behavior which is implemented for FreeBSD. Use of the libmount library was originally considered because it provides functionality to properly lock and update the /etc/mtab file. However, these days /etc/mtab is typically a symlink to /proc/self/mounts so there's nothing to updated. Therefore, we call mount(2) directly and avoid any additional dependencies. If required the legacy behavior can be enabled by setting the ZFS_MOUNT_HELPER environment variable. This may be needed in environments where SELinux in enabled and the zfs binary does not have mount permission.

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes. Add a missing call to fnvlist_free(nvl) in log_internal() that was added in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time (zfsonlinux/zfs@9e11c73) because it depended on future work.
