This results in a couple of bugs in the recv code: - received properties are not restored correctly when failing to receive an incremental send stream - received properties are not completely replaced by the new ones when successfully receiving an incremental send stream This was discovered on ZFS on Linux (fixed in https://github.com/zfsonlinux/zfs/commit/5f1346c29997dd4e02acf4c19c875d5484f33b1e) Reviewed by: Paul Dagnelie Reviewed by: Matthew Ahrens Approved by: Dan McDonald Author: loli10K Modified: stable/11/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c Directory Properties: stable/11/ (props changed) Modified: stable/11/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c ============================================================================== --- stable/11/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c Mon Apr 16 03:42:06 2018 (r332532) +++ stable/11/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c Mon Apr 16 03:42:47 2018 (r332533) @@ -856,11 +856,15 @@ dsl_props_set_sync_impl(dsl_dataset_t *ds, zprop_sourc while ((elem = nvlist_next_nvpair(props, elem)) != NULL) { nvpair_t *pair = elem; + const char *name = nvpair_name(pair); if (nvpair_type(pair) == DATA_TYPE_NVLIST) { /* - * dsl_prop_get_all_impl() returns properties in this - * format. + * This usually happens when we reuse the nvlist_t data + * returned by the counterpart dsl_prop_get_all_impl(). + * For instance we do this to restore the original + * received properties when an error occurs in the + * zfs_ioc_recv() codepath. */ nvlist_t *attrs = fnvpair_value_nvlist(pair); pair = fnvlist_lookup_nvpair(attrs, ZPROP_VALUE); @@ -868,14 +872,14 @@ dsl_props_set_sync_impl(dsl_dataset_t *ds, zprop_sourc if (nvpair_type(pair) == DATA_TYPE_STRING) { const char *value = fnvpair_value_string(pair); - dsl_prop_set_sync_impl(ds, nvpair_name(pair), + dsl_prop_set_sync_impl(ds, name, source, 1, strlen(value) + 1, value, tx); } else if (nvpair_type(pair) == DATA_TYPE_UINT64) { uint64_t intval = fnvpair_value_uint64(pair); - dsl_prop_set_sync_impl(ds, nvpair_name(pair), + dsl_prop_set_sync_impl(ds, name, source, sizeof (intval), 1, &intval, tx); } else if (nvpair_type(pair) == DATA_TYPE_BOOLEAN) { - dsl_prop_set_sync_impl(ds, nvpair_name(pair), + dsl_prop_set_sync_impl(ds, name, source, 0, 0, NULL, tx); } else { panic("invalid nvpair type");
