" It seems that this commit causes a crash in zfs(1) when e.g. 'zfs list' is executed and one of the filesystems has a user property set on it. The crash is in zfs_prune_proplist function at cddl/contrib/opensolaris/lib/libzfs/common/libzfs_dataset.c:4291. " The issue has been fixed in OpenSolaris onnv-gate revision 9396. An associated OpenSolaris bug-id cannot be determined. Solution: partial vendor import of OpenSolaris rev. 9396 (just the bugfix) References: http://src.opensolaris.org/source/diff/onnv/onnv-gate/usr/src/lib/libzfs/common/libzfs_dataset.c?r2=%252Fonnv%252Fonnv-gate%252Fusr%252Fsrc%252Flib%252Flibzfs%252Fcommon%252Flibzfs_dataset.c%409396%3Af41cf682d0d3&r1=%252Fonnv%252Fonnv-gate%252Fusr%252Fsrc%252Flib%252Flibzfs%252Fcommon%252Flibzfs_dataset.c%408845%3A91af0d9c0790 >How-To-Repeat: >Fix: @@ -4488,7 +3934,12 @@ zfs_prop_t zfs_prop = zfs_name_to_prop(nvpair_name(curr)); nvpair_t *next = nvlist_next_nvpair(zhp->zfs_props, curr); - if (props[zfs_prop] == B_FALSE) + /* + * We leave user:props in the nvlist, so there will be + * some ZPROP_INVAL.
