Summary (updated)
-----------------
5592 NULL pointer dereference in dsl_prop_notify_all_cb()
Bugs: 5592
https://www.illumos.org/projects/illumos-gate//issues/5592
Repository: illumos-gate
Description
-------
Follow on to /r/153.
uts/common/fs/zfs/dsl_dataset.c:
Close race in dsl_dataset_try_add_ref() where the dsl_dataset_t
still points to a valid bonus buffer, but that bonus buffer is
held by a new dsl_dataset_t instance for this dataset. Allow
the add_ref operation only if the passed in dsl_dataset_t owns
its referenced bonus buffer - the dbuf user for the bonus
buffer is this dsl_dataset_t.
