However, these l0 holes do not have the birth time property set; as a result, incremental sends will not send those holes. Fix is to modify the dbuf_read code to fill in birth time data.
* Fix NFS credentialChunwei Chen2016-06-213-12/+10
| | | | | | | | | | | | | | | | The commit f74b821 caused a regression where creating file through NFS will always create a file owned by root. This is because the patch enables the KSID code in zfs_acl_ids_create, which it would use euid and egid of the current process. However, on Linux, we should use fsuid and fsgid for file operations, which is the original behaviour. So we revert this part of code. The patch also enables secpolicy_vnode_*, since they are also used in file operations, we change them to use fsuid and fsgid.

* SIMD implementation of vdev_raidz generate and reconstruct routinesGvozden Neskovic2016-06-2131-161/+6811
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new implementation of RAIDZ1/2/3 routines using x86_64 scalar, SSE, and AVX2 instruction sets. Included are 3 parity generation routines (P, PQ, and PQR) and 7 reconstruction routines, for all RAIDZ level. On module load, a quick benchmark of supported routines will select the fastest for each operation and they will be used at runtime. Original implementation is still present and can be selected via module parameter. Patch contains: - specialized gen/rec routines for all RAIDZ levels, - new scalar raidz implementation (unrolled), - two x86_64 SIMD implementations (SSE and AVX2 instructions sets), - fastest routines selected on module load (benchmark). - cmd/raidz_test - verify and benchmark all implementations - added raidz_test to the ZFS Test Suite New zfs module parameters: - zfs_vdev_raidz_impl (str): selects the implementation to use. On module load, the parameter will only accept first 3 options, and the other implementations can be set once module is finished loading. Possible values for this option are: "fastest" - use the fastest math available "original" - use the original raidz code "scalar" - new scalar impl "sse" - new SSE impl if available "avx2" - new AVX2 impl if available See contents of `/sys/module/zfs/parameters/zfs_vdev_raidz_impl` to get the list of supported values. If an implementation is not supported on the system, it will not be shown. Currently selected option is enclosed in `[]`.

* Linux 4.6 compat: Fall back to d_prune_aliases() if necessaryTim Chase2016-06-171-2/+15
| | | | | | | | | | | | | | | As of 4.6, the icache and dcache LRUs are memcg aware insofar as the kernel's per-superblock shrinker is concerned. The effect is that dcache or icache entries added by a task in a non-root memcg won't be scanned by the shrinker in the context of the root (or NULL) memcg. This defeats the attempts by zfs_sb_prune() to unpin buffers and can allow metadata to grow uncontrollably. This patch reverts to the d_prune_aliaes() method in case the kernel's per-superblock shrinker is not able to free anything.

* Add `zfs allow` and `zfs unallow` supportBrian Behlendorf2016-06-0778-242/+759
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ZFS allows for specific permissions to be delegated to normal users with the `zfs allow` and `zfs unallow` commands. In addition, non- privileged users should be able to run all of the following commands: * zpool [list | iostat | status | get] * zfs [list | get] Historically this functionality was not available on Linux. In order to add it the secpolicy_* functions needed to be implemented and mapped to the equivalent Linux capability. Only then could the permissions on the `/dev/zfs` be relaxed and the internal ZFS permission checks used. Even with this change some limitations remain. Under Linux only the root user is allowed to modify the namespace (unless it's a private namespace). This means the mount, mountpoint, canmount, unmount, and remount delegations cannot be supported with the existing code. It may be possible to add this functionality in the future. This functionality was validated with the cli_user and delegation test cases from the ZFS Test Suite. These tests exhaustively verify each of the supported permissions which can be delegated and ensures only an authorized user can perform it. Two minor bug fixes were required for test-running.py. First, the Timer() object cannot be safely created in a `try:` block when there is an unconditional `finally` block which references it. Second, when running as a normal user also check for scripts using the both the .ksh and .sh suffixes. Finally, existing users who are simulating delegations by setting group permissions on the /dev/zfs device should revert that customization when updating to a version with this change.

* Fix self-healing IO prior to dsl_pool_init() completionGeLiXin2016-05-272-6/+23
| | | | | | | | | | | | | | | | | | | | | Async writes triggered by a self-healing IO may be issued before the pool finishes the process of initialization. This results in a NULL dereference of `spa->spa_dsl_pool` in vdev_queue_max_async_writes(). George Wilson recommended addressing this issue by initializing the passed `dsl_pool_t **` prior to dmu_objset_open_impl(). Since the caller is passing the `spa->spa_dsl_pool` this has the effect of ensuring it's initialized. However, since this depends on the caller knowing they must pass the `spa->spa_dsl_pool` an additional NULL check was added to vdev_queue_max_async_writes(). This guards against any future restructuring of the code which might result in dsl_pool_init() being called differently.

| | | | | | | | | | | | | | | | Add argument format to print_one_column(), and use it to call zfs_nicenum_format with, instead of just zfs_nicenum. Don't print "%" for fragmentation or capacity percent values. The calls to print_one_colum is made with ZFS_NICENUM_RAW if cb->cb_literal (zpool list called with -p), and ZFS_NICENUM_1024 if not. Also zpool_get_prop is modified to don't add "%" or "x" if literal.

* Use zfs range locks in ztestBoris Protopopov2016-05-173-55/+157
| | | | | | | | | | | | | The zfs range lock interface no longer tightly depends on a znode_t and therefore can be used in ztest. This allows the previous ztest specific implementation to be removed, and for additional test coverage of the shared version.

* Remove dummy znode from zvol_stateChunwei Chen2016-05-178-76/+105
| | | | | | | | | | | | | | | | | | | | | | struct zvol_state contains a dummy znode, which is around 1KB on x64, only for zfs_range_lock. But in reality, other than z_range_lock and z_range_avl, zfs_range_lock only need znode on regular file, which means we add 1KB on a structure and gain nothing. In this patch, we remove the dummy znode for zvol_state. In order to do that, we also need to refactor zfs_range_lock a bit. We move z_range_lock and z_range_avl pair out of znode_t to form zfs_rlock_t. This new struct replaces znode_t as the main handle inside the range lock functions. We also add pointers to z_size, z_blksz, and z_max_blksz so range lock code doesn't depend on znode_t. This allows non-ZPL consumers like Lustre to use the range locks with their equivalent znode_t structure.
