9512 zfs remap poolname@snapname coredumps
Only filesystems and volumes are valid "zfs remap" parameters: when passed a snapshot name zfs_remap_indirects() does not handle the EINVAL returned from libzfs_core, which results in failing an assertion and consequently crashing. illumos/illumos-gate@0b2e8253986c5c761129b58cfdac46d204903de1 Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: John Wren Kennedy <john.kennedy@delphix.com> Reviewed by: Sara Hartse <sara.hartse@delphix.com> Approved by: Matt Ahrens <mahrens@delphix.com> Author: loli10K <ezomori.nozomu@gmail.com>
