A typical * use-case is with a delegated dataset where the administrator wants to ensure * that a user within the zone is not creating too many additional filesystems * or snapshots, even though they're not exceeding their space quota. * * The filesystem and snapshot counts are stored as extensible properties. This * capability is controlled by a feature flag and must be enabled to be used. * Once enabled, the feature is not active until the first limit is set. At * that point, future operations to create/destroy filesystems or snapshots * will validate and update the counts. * * Because the count properties will not exist before the feature is active, * the counts are updated when a limit is first set on an uninitialized * dsl_dir node in the tree (The filesystem/snapshot count on a node includes * all of the nested filesystems/snapshots. Thus, a new leaf node has a * filesystem count of 0 and a snapshot count of 0. Non-existent filesystem and * snapshot count properties on a node indicate uninitialized counts on that * node.) When first setting a limit on an uninitialized node, the code starts * at the filesystem with the new limit and descends into all sub-filesystems * to add the count properties. * * In practice this is lightweight since a limit is typically set when the * filesystem is created and thus has no children. Once valid, changing the * limit value won't require a re-traversal since the counts are already valid. * When recursively fixing the counts, if a node with a limit is encountered * during the descent, the counts are known to be valid and there is no need to * descend into that filesystem's children. The counts on filesystems above the * one with the new limit will still be uninitialized, unless a limit is * eventually set on one of those filesystems. The counts are always recursively * updated when a limit is set on a dataset, unless there is already a limit. * When a new limit value is set on a filesystem with an existing limit, it is * possible for the new limit to be less than the current count at that level * since a user who can change the limit is also allowed to exceed the limit. * * Once the feature is active, then whenever a filesystem or snapshot is * created, the code recurses up the tree, validating the new count against the * limit at each initialized level. In practice, most levels will not have a * limit set. If there is a limit at any initialized level up the tree, the * check must pass or the creation will fail. Likewise, when a filesystem or * snapshot is destroyed, the counts are recursively adjusted all the way up * the initialized nodes in the tree. Renaming a filesystem into different point * in the tree will first validate, then update the counts on each branch up to * the common ancestor. A receive will also validate the counts and then update * them. * * An exception to the above behavior is that the limit is not enforced if the * user has permission to modify the limit. This is primarily so that * recursive snapshots in the global zone always work. We want to prevent a * denial-of-service in which a lower level delegated dataset could max out its * limit and thus block recursive snapshots from being taken in the global zone. * Because of this, it is possible for the snapshot count to be over the limit * and snapshots taken in the global zone could cause a lower level dataset to * hit or exceed its limit. The administrator taking the global zone recursive * snapshot should be aware of this side-effect and behave accordingly. * For consistency, the filesystem limit is also not enforced if the user can * modify the limit. * * The filesystem and snapshot limits are validated by dsl_fs_ss_limit_check() * and updated by dsl_fs_ss_count_adjust(). A new limit value is setup in * dsl_dir_activate_fs_ss_limit() and the counts are adjusted, if necessary, by * dsl_dir_init_fs_ss_count(). - * - * There is a special case when we receive a filesystem that already exists. In - * this case a temporary clone name of %X is created (see dmu_recv_begin). We - * never update the filesystem counts for temporary clones. - * - * Likewise, we do not update the snapshot counts for temporary snapshots, - * such as those created by zfs diff. */ extern inline dsl_dir_phys_t *dsl_dir_phys(dsl_dir_t *dd); static uint64_t dsl_dir_space_towrite(dsl_dir_t *dd); typedef struct ddulrt_arg { dsl_dir_t *ddulrta_dd; uint64_t ddlrta_txg; } ddulrt_arg_t; static void dsl_dir_evict_async(void *dbu) { dsl_dir_t *dd = dbu; int t; dsl_pool_t *dp __maybe_unused = dd->dd_pool; dd->dd_dbuf = NULL; for (t = 0; t < TXG_SIZE; t++) { ASSERT(!txg_list_member(&dp->dp_dirty_dirs, dd, t)); ASSERT(dd->dd_tempreserved[t] == 0); ASSERT(dd->dd_space_towrite[t] == 0); } if (dd->dd_parent) dsl_dir_async_rele(dd->dd_parent, dd); spa_async_close(dd->dd_pool->dp_spa, dd); if (dsl_deadlist_is_open(&dd->dd_livelist)) dsl_dir_livelist_close(dd); dsl_prop_fini(dd); cv_destroy(&dd->dd_activity_cv); mutex_destroy(&dd->dd_activity_lock); mutex_destroy(&dd->dd_lock); kmem_free(dd, sizeof (dsl_dir_t)); } int dsl_dir_hold_obj(dsl_pool_t *dp, uint64_t ddobj, const char *tail, void *tag, dsl_dir_t **ddp) { dmu_buf_t *dbuf; dsl_dir_t *dd; dmu_object_info_t doi; int err; ASSERT(dsl_pool_config_held(dp)); err = dmu_bonus_hold(dp->dp_meta_objset, ddobj, tag, &dbuf); if (err != 0) return (err); dd = dmu_buf_get_user(dbuf); dmu_object_info_from_db(dbuf, &doi); ASSERT3U(doi.doi_bonus_type, ==, DMU_OT_DSL_DIR); ASSERT3U(doi.doi_bonus_size, >=, sizeof (dsl_dir_phys_t)); if (dd == NULL) { dsl_dir_t *winner; dd = kmem_zalloc(sizeof (dsl_dir_t), KM_SLEEP); dd->dd_object = ddobj; dd->dd_dbuf = dbuf; dd->dd_pool = dp; mutex_init(&dd->dd_lock, NULL, MUTEX_DEFAULT, NULL); mutex_init(&dd->dd_activity_lock, NULL, MUTEX_DEFAULT, NULL); cv_init(&dd->dd_activity_cv, NULL, CV_DEFAULT, NULL); dsl_prop_init(dd); if (dsl_dir_is_zapified(dd)) { err = zap_lookup(dp->dp_meta_objset, ddobj, DD_FIELD_CRYPTO_KEY_OBJ, sizeof (uint64_t), 1, &dd->dd_crypto_obj); if (err == 0) { /* check for on-disk format errata */ if (dsl_dir_incompatible_encryption_version( dd)) { dp->dp_spa->spa_errata = ZPOOL_ERRATA_ZOL_6845_ENCRYPTION; } } else if (err != ENOENT) { goto errout; } } dsl_dir_snap_cmtime_update(dd); if (dsl_dir_phys(dd)->dd_parent_obj) { err = dsl_dir_hold_obj(dp, dsl_dir_phys(dd)->dd_parent_obj, NULL, dd, &dd->dd_parent); if (err != 0) goto errout; if (tail) { #ifdef ZFS_DEBUG uint64_t foundobj; err = zap_lookup(dp->dp_meta_objset, dsl_dir_phys(dd->dd_parent)-> dd_child_dir_zapobj, tail, sizeof (foundobj), 1, &foundobj); ASSERT(err || foundobj == ddobj); #endif (void) strlcpy(dd->dd_myname, tail, sizeof (dd->dd_myname)); } else { err = zap_value_search(dp->dp_meta_objset, dsl_dir_phys(dd->dd_parent)-> dd_child_dir_zapobj, ddobj, 0, dd->dd_myname); } if (err != 0) goto errout; } else { (void) strlcpy(dd->dd_myname, spa_name(dp->dp_spa), sizeof (dd->dd_myname)); } if (dsl_dir_is_clone(dd)) { dmu_buf_t *origin_bonus; dsl_dataset_phys_t *origin_phys; /* * We can't open the origin dataset, because * that would require opening this dsl_dir. * Just look at its phys directly instead. */ err = dmu_bonus_hold(dp->dp_meta_objset, dsl_dir_phys(dd)->dd_origin_obj, FTAG, &origin_bonus); if (err != 0) goto errout; origin_phys = origin_bonus->db_data; dd->dd_origin_txg = origin_phys->ds_creation_txg; dmu_buf_rele(origin_bonus, FTAG); if (dsl_dir_is_zapified(dd)) { uint64_t obj; err = zap_lookup(dp->dp_meta_objset, dd->dd_object, DD_FIELD_LIVELIST, sizeof (uint64_t), 1, &obj); if (err == 0) dsl_dir_livelist_open(dd, obj); else if (err != ENOENT) goto errout; } } dmu_buf_init_user(&dd->dd_dbu, NULL, dsl_dir_evict_async, &dd->dd_dbuf); winner = dmu_buf_set_user_ie(dbuf, &dd->dd_dbu); if (winner != NULL) { if (dd->dd_parent) dsl_dir_rele(dd->dd_parent, dd); if (dsl_deadlist_is_open(&dd->dd_livelist)) dsl_dir_livelist_close(dd); dsl_prop_fini(dd); cv_destroy(&dd->dd_activity_cv); mutex_destroy(&dd->dd_activity_lock); mutex_destroy(&dd->dd_lock); kmem_free(dd, sizeof (dsl_dir_t)); dd = winner; } else { spa_open_ref(dp->dp_spa, dd); } } /* * The dsl_dir_t has both open-to-close and instantiate-to-evict * holds on the spa.
