Description Xin LI freebsd_committer 2020-04-24 19:01:24 UTC 
As of r304321, boot loader gained support of SHA512 and Skein; setting checksum=skein should be allowed for boot filesystems.

Same as https://www.illumos.org/issues/8906 .  Illumos change https://github.com/illumos/illumos-gate/commit/0dd498c0020c4a0dd34d350b07f97399a475d102 should be applied on FreeBSD too.

Comment 2 Kubilay Kocak freebsd_committer freebsd_triage 2020-06-20 02:47:43 UTC 
^Triage: Has this been merged to stable/11 already (mfc-stable +), or is it pending? base r362396 did't have an MFC flag, so unsure.

If its already been merged, please add a "base rXXXXX" to autolink to the merge commit in a comment and set mfc-stable12 to + again, otherwise please reference this PR: in a subsequent merge and set it to + after the merge is complete

Comment 4 VVD 2020-07-27 07:11:34 UTC 
Sorry for noise, maybe I misunderstand…
In man page of this patch (cddl/contrib/opensolaris/cmd/zfs/zfs.8) "The salted checksum algorithm is currently not supported on FreeBSD.", but in "sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_ioctl.c" if section "Salted checksums are not supported on root pools." was removed.
So are salted checksums supported on FreeBSD or not? And on root/boot pools?
Comment 5 Allan Jude freebsd_committer 2020-07-28 02:15:28 UTC 
Skein is supported, for root/boot

Edon-r is not supported at all (not even to mount the filesystem)
