* Suspend/resume zvol for recv and rollbackChunwei Chen2017-01-194-42/+168
| | | | | | | | | | | | | | | | When doing recv and rollback, dsl_dataset_clone_swap_sync_impl will be called to swap out the ds_objset and do dmu_objset_evict on the old one. However, currently zv->zv_objset will not be swapped out accordingly, so if anyone currently holds a fd on the zvol, we risk hitting a use-after-free. We fix this by introducing the suspend and resume mechanism of zsb to zv. Before recv or rollback, we use zvol_suspend to block all access to zv_objset and shut it down. After the recv or rollback, we use zvol_resume to swap in zv_objset with the new ds_objset and unblock the access.

This appears to be because the logic that would have done so, in spa_sync_config_object(), is not reached under normal operation. It is only reached if spa_config_dirty_list is non-empty. The fix is to add another `AVZ_ACTION_` enum that will allow this code to be reached when we detect that we're loading an old pool, even when there are no dirty configs.

* Use a dedicated taskq for vdev_fileChunwei Chen2016-12-213-2/+24
| | | | | | | | | | | | | | | | | The introduction of parallel zvol prefetch causes deadlock when using vdev_file. spa_async->(spa_namespace_lock)->txg_wait_synced->(wait for txg_sync) txg_sync->zio_wait->(wait for vdev_file_io_fsync on system_taskq) zvol_prefetch_minors_impl (on system_taskq)->spa_open_common->(wait for spa_namespace_lock) We fix this by using dedicated taskq for vdev_file. This same change was originally made in commit bc25c93 but reverted in commit aa9af22 when dynamic taskqs were added.

* Fix dsl_props_set_sync_impl to work with nested nvlistLOLi2016-12-204-7/+134
| | | | | | | | | | | | | | | When iterating over the input nvlist in dsl_props_set_sync_impl() when we don't preserve the nvpair name before looking up ZPROP_VALUE, so when we later go to process it nvpair_name() is always "value" and not the actual property name. This fixes a couple of bugs in zfs_ioc_recv(): * Received properties were not restored correctly when failing to receive an incremental send stream * Received properties were not completely replaced by the new ones when successfully receiving an incremental send stream Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: loli10K <[email protected]> Closes #5497

| | | | | | | | | | | | | | | | The fchange in zpl_ioctl_setflags was for detecting flag change. However it was incorrect and would always fail to detect a flag change from set to unset, causing users without CAP_LINUX_IMMUTABLE to be able to unset flags.
