* zfs userspace dumps core when used on ZVOLsloli10K2019-01-251-2/+12
| | | | | | | | | | | If you try to get the userspace, groupspace or projectspace on a ZVOL, the generated error results in passing EINVAL to zfs_standard_error_fmt() when we should return a specific error to inform the user that those properties aren't available on volumes.

* Disable 'zfs remap' commandBrian Behlendorf2019-01-151-1/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of 'zfs remap' has proven to be problematic since it modifies the objset (but not its logical contents) by dirtying metadata without owning it. The consequence of which is that dmu_objset_remap_indirects() is vulnerable to certain races. For example, if we are in the middle of receiving into the filesystem while it is being remapped. Then it is possible we could evict the objset when the receive completes (see dsl_dataset_clone_swap_sync_impl, or dmu_recv_end_sync), but dmu_objset_remap_indirects() may be still using the objset. The result of which would be a panic. Extended runs of ztest(8) have exposed other possible races which can occur when using 'zfs remap'. Several of these have been fixed but there may be others which have not yet been encountered and diagnosed. Furthermore, the ability to manually remap a filesystem is no longer particularly useful now that the removal code can map large chunks. Coupled with the fact that explaining what this command does and why it may be useful requires a detailed understanding of the internals of device removal. These are details users should not be bothered with. Therefore, the 'zfs remap' command is being disabled but not entirely removed. It may be removed in the future or potentially reworked to address the issues described above. Since 'zfs remap' has never been part of a tagged release its removal is expected to have minimal impact. The ZTS tests have been updated to continue to exercise the command to prevent atrophy, but it has been removed entirely from ztest(8).

* Add basic zfs ioc input nvpair validationDon Brady2018-09-021-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want newer versions of libzfs_core to run against an existing zfs kernel module (i.e. a deferred reboot or module reload after an update). Programmatically document, via a zfs_ioc_key_t, the valid arguments for the ioc commands that rely on nvpair input arguments (i.e. non legacy commands from libzfs_core). Automatically verify the expected pairs before dispatching a command. This initial phase focuses on the non-legacy ioctls. A follow-on change can address the legacy ioctl input from the zfs_cmd_t. The zfs_ioc_key_t for zfs_keys_channel_program looks like: static const zfs_ioc_key_t zfs_keys_channel_program[] = { {"program", DATA_TYPE_STRING, 0}, {"arg", DATA_TYPE_UNKNOWN, 0}, {"sync", DATA_TYPE_BOOLEAN_VALUE, ZK_OPTIONAL}, {"instrlimit", DATA_TYPE_UINT64, ZK_OPTIONAL}, {"memlimit", DATA_TYPE_UINT64, ZK_OPTIONAL}, }; Introduce four input errors to identify specific input failures (in addition to generic argument value errors like EINVAL, ERANGE, EBADF, and E2BIG).

* OpenZFS 7614, 9064 - zfs device evacuation/removalMatthew Ahrens2018-04-141-1/+24

This operation copies all allocated regions of the device to be removed onto other devices, recording the mapping from old to new location. After the removal is complete, read and free operations to the removed (now "indirect") vdev must be remapped and performed at the new location on disk. The indirect mapping table is kept in memory whenever the pool is loaded, so there is minimal performance overhead when doing operations on the indirect vdev. The size of the in-memory mapping table will be reduced when its entries become "obsolete" because they are no longer used by any block pointers in the pool. An entry becomes obsolete when all the blocks that use it are freed. An entry can also become obsolete when all the snapshots that reference it are deleted, and the block pointers that reference it have been "remapped" in all filesystems/zvols (and clones). Whenever an indirect block is written, all the block pointers in it will be "remapped" to their new (concrete) locations if possible. This process can be accelerated by using the "zfs remap" command to proactively rewrite all indirect blocks that reference indirect (removed) vdevs. Note that when a device is removed, we do not verify the checksum of the data that is copied. This makes the process much faster, but if it were used on redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy the wrong data, when we have the correct data on e.g. the other side of the mirror. At the moment, only mirrors and simple top-level vdevs can be removed and no removal is allowed if any of the top-level vdevs are raidz. Porting Notes: * Avoid zero-sized kmem_alloc() in vdev_compact_children(). The device evacuation code adds a dependency that vdev_compact_children() be able to properly empty the vdev_child array by setting it to NULL and zeroing vdev_children. Under Linux, kmem_alloc() and related functions return a sentinel pointer rather than NULL for zero-sized allocations. * Remove comment regarding "mpt" driver where zfs_remove_max_segment is initialized to SPA_MAXBLOCKSIZE. Change zfs_condense_indirect_commit_entry_delay_ticks to zfs_condense_indirect_commit_entry_delay_ms for consistency with most other tunables in which delays are specified in ms. * ZTS changes: Use set_tunable rather than mdb Use zpool sync as appropriate Use sync_pool instead of sync Kill jobs during test_removal_with_operation to allow unmount/export Don't add non-disk names such as "mirror" or "raidz" to $DISKS Use $TEST_BASE_DIR instead of /tmp Increase HZ from 100 to 1000 which is more common on Linux removal_multiple_indirection.ksh Reduce iterations in order to not time out on the code coverage builders. removal_resume_export: Functionally, the test case is correct but there exists a race where the kernel thread hasn't been fully started yet and is not visible. Wait for up to 1 second for the removal thread to be started before giving up on it. Also, increase the amount of data copied in order that the removal not finish before the export has a chance to fail. * MMP compatibility, the concept of concrete versus non-concrete devices has slightly changed the semantics of vdev_writeable(). Update mmp_random_leaf_impl() accordingly. * Updated dbuf_remap() to handle the org.zfsonlinux:large_dnode pool feature which is not supported by OpenZFS. * Added support for new vdev removal tracepoints. * Test cases removal_with_zdb and removal_condense_export have been intentionally disabled. When run manually they pass as intended, but when running in the automated test environment they produce unreliable results on the latest Fedora release. They may work better once the upstream pool import refectoring is merged into ZoL at which point they will be re-enabled.

This patch ports Joyent's JSON nvlist library from illumos to enable easy JSON printing of channel program output nvlist.

Similar as user/group quota, project quota is another dimension of system quota. It bases on the new object attribute - project ID. Project ID is a numerical value to indicate to which project an object belongs. An object only can belong to one project though you (the object owner or privileged user) can change the object project ID via 'chattr -p' or 'zfs project [-s] -p' explicitly. The object also can inherit the project ID from its parent when created if the parent has the project inherit flag (that can be set via 'chattr +P' or 'zfs project -s [-p]'). By accounting the spaces/objects belong to the same project, we can know how many spaces/objects used by the project. And if we set the upper limit then we can control the spaces/objects that are consumed by such project. It is useful when multiple groups and users cooperate for the same project, or a user/group needs to participate in multiple projects. Support the following commands and functionalities: zfs set projectquota@project zfs set projectobjquota@project zfs get projectquota@project zfs get projectobjquota@project zfs get projectused@project zfs get projectobjused@project zfs projectspace zfs allow projectquota zfs allow projectobjquota zfs allow projectused zfs allow projectobjused zfs unallow projectquota zfs unallow projectobjquota zfs unallow projectused zfs unallow projectobjused chattr +/-P chattr -p project_id lsattr -p This patch also supports tree quota based on the project quota via "zfs project" commands set as following: zfs project [-d|-r] <file|directory ...> zfs project -C [-k] [-r] <file|directory ...> zfs project -c [-0] [-d|-r] [-p id] <file|directory ...> zfs project [-p id] [-r] [-s] <file|directory ...> For "df [-i] $DIR" command, if we set INHERIT (project ID) flag on the $DIR, then the proejct [obj]quota and [obj]used values for the $DIR's project ID will be shown as the total/free (avail) resource.

This would greatly improve performance for channel programs that just gather information, as they won't have to wait for synching context anymore. === What is implemented?

(The -n option) - A new flag/option within the channel program ioctl which selects the context. - Appropriate error handling whenever we try a channel program in open-context that contains zfs.sync* expressions. - Documentation for the new feature in the manual pages. === How do we handle zfs.sync functions in open context? When such a function is found by the interpreter and we are running in open context we abort the script and we spit out a descriptive runtime error. For example, given the script below ... arg = ... fs = arg["argv"][1] err = zfs.sync.destroy(fs) msg = "destroying " .. fs .. " err=" .. err return msg if we run it in open context, we will get back the following error: Channel program execution failed: [string "channel program"]:3: running functions from the zfs.sync submodule requires passing sync=TRUE to lzc_channel_program() (i.e. do not specify the "-n" command line argument) stack traceback: [C]: in function 'destroy' [string "channel program"]:3: in main chunk === What about testing? We've introduced new wrappers for all channel program tests that run each channel program as both (startard & open-context) and expect the appropriate behavior depending on the program using the zfs.sync module.

* Encryption Stability and On-Disk Format FixesTom Caputi2018-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The on-disk format for encrypted datasets protects not only the encrypted and authenticated blocks themselves, but also the order and interpretation of these blocks. In order to make this work while maintaining the ability to do raw sends, the indirect bps maintain a secure checksum of all the MACs in the block below it along with a few other fields that determine how the data is interpreted. Unfortunately, the current on-disk format erroneously includes some fields which are not portable and thus cannot support raw sends. It is not possible to easily work around this issue due to a separate and much smaller bug which causes indirect blocks for encrypted dnodes to not be compressed, which conflicts with the previous bug. In addition, the current code generates incompatible on-disk formats on big endian and little endian systems due to an issue with how block pointers are authenticated. Finally, raw send streams do not currently include dn_maxblkid when sending both the metadnode and normal dnodes which are needed in order to ensure that we are correctly maintaining the portable objset MAC. This patch zero's out the offending fields when computing the bp MAC and ensures that these MACs are always calculated in little endian order (regardless of the host system's byte order). This patch also registers an errata for the old on-disk format, which we detect by adding a "version" field to newly created DSL Crypto Keys. We allow datasets without a version (version 0) to only be mounted for read so that they can easily be migrated. We also now include dn_maxblkid in raw send streams to ensure the MAC can be maintained correctly. This patch also contains minor bug fixes and cleanups.

* Native Encryption for ZFS on LinuxTom Caputi2017-08-141-8/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

* Add libtpool (thread pools)Brian Behlendorf2017-08-092-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenZFS provides a library called tpool which implements thread pools for user space applications. Porting this library means the zpool utility no longer needs to borrow the kernel mutex and taskq interfaces from libzpool. This code was updated to use the tpool library which behaves in a very similar fashion. Porting libtpool was relatively straight forward and minimal modifications were needed. The core changes were: * Fully convert the library to use pthreads. * Updated signal handling. * lmalloc/lfree converted to calloc/free * Implemented portable pthread_attr_clone() function. Finally, update the build system such that libzpool.so is no longer linked in to zfs(8), zpool(8), etc. All that is required is libzfs to which the zcommon soures were added (which is the way it always should have been). Removing the libzpool dependency resulted in several build issues which needed to be resolved. * Moved zfeature support to module/zcommon/zfeature_common.c * Moved ratelimiting to to module/zfs/zfs_ratelimit.c * Moved get_system_hostid() to lib/libspl/gethostid.c * Removed use of cmn_err() in zcommon source * Removed dprintf_setup() call from zpool_main.c and zfs_main.c * Removed highbit() and lowbit() * Removed unnecessary library dependencies from Makefiles * Removed fletcher-4 kstat in user space * Added sha2 support explicitly to libzfs * Added highbit64() and lowbit64() to zpool_util.c Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #6442

* OpenZFS 7742 - zfs send wrong error message with invalid long optsGeorge Melikov2017-01-311-4/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two cases: 1. if an invalid flag is passed, and 2. if a valid flag is not given a parameter. In the case of (1), the flag is either short or long. For short flags, optopt contains the character of the flag. For long, it contains zero, and we can access the long flag using argv and optind. In the case of (2), if the flag is short, optopt contains the character of the flag. If the flag is long, the value in the 4th column of the long_options table, for that flag, is returned. We could case over all those values, or we could simply use argv and optind again. Note that in the case of something like `--resume`, which is also `-t`, "t" will be returned if an argument is not provided; so the error message will say `'t': argument not provided` or similar. This could be fixed by making it so long and short options don't use the same character flag, and then combining them in the switch/case statement, but I didn't think the ugliness of the code would be worth the small usability enhancement.
