+Topic:          ZFS data loss
+
+Category:       contrib
+Module:         zfs
+Announced:      2022-03-21
+Affects:        FreeBSD 13.0-p8
+Corrected:      2022-03-20 14:10:36 UTC (releng/13.0, 13.0-RELEASE-p9)
+
+For general information regarding FreeBSD Errata Notices and Security
+Advisories, including descriptions of the fields above, security
+branches, and the following sections, please visit
+<URL:https://security.FreeBSD.org/>.
+
+I.   Background
+
+ZFS is one of several filesystems available on FreeBSD.  ZFS supports
+many advanced features, including checksumming, transparent compression,
+and snapshots.
+
+II.  Problem Description
+
+Erratum FreeBSD-EN-22:11.zfs was addressed by a patch which modified a
+ZFS kernel function that determines whether the in-memory copy of a
+filesystem object is dirty with respect to its representation on stable
+storage.  The modification contained a bug which could cause the
+function to return false negatives.
+
+III. Impact
+
+Under heavy load, files written to a ZFS filesystem may not be correctly
+saved to disk.
+
+IV.  Workaround
+
+No workaround is available, but systems not using ZFS are not affected.
+
+V.   Solution
+
+Upgrade your system to a supported FreeBSD stable or release / security
+branch (releng) dated after the correction date and reboot.
+
+Perform one of the following:
+
+1) To update your system via a binary patch:
+
+Systems running a RELEASE version of FreeBSD on the amd64, i386, or
+(on FreeBSD 13 and later) arm64 platforms can be updated via the
+freebsd-update(8) utility:
+
+# freebsd-update fetch
+# freebsd-update install
+# shutdown -r +10min "Rebooting for an errata update"
+
+2) To update your system via a source code patch:
+
+The following patches have been verified to apply to the applicable
+FreeBSD release branches.
+
+a) Download the relevant patch from the location below, and verify the
+detached PGP signature using your PGP utility.
+
+# fetch https://security.FreeBSD.org/patches/EN-22:13/zfs.patch
+# fetch https://security.FreeBSD.org/patches/EN-22:13/zfs.patch.asc
+# gpg --verify zfs.patch.asc
+
+b) Apply the patch.  Execute the following commands as root:
+
+# cd /usr/src
+# patch < /path/to/patch
+
+c) Recompile your kernel as described in
+<URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the
+system.
+
+VI.  Correction details
+
+This issue is corrected by the corresponding Git commit hash or Subversion
+revision number in the following stable and release branches:
+
+Branch/path                             Hash                     Revision
+- -------------------------------------------------------------------------
+releng/13.0/                            b8ae329db949  releng/13.0-n244788
+- -------------------------------------------------------------------------
+
+For FreeBSD 13 and later:
+
+Run the following command to see which files were modified by a
+particular commit:
+
+# git show --stat NNNNNNNNNNNN
+
+Or visit the following URL, replacing NNNNNN with the hash:
+
+<URL:https://cgit.freebsd.org/src/commit/?id=NNNNNNNNNNNN>
+
+To determine the commit count in a working tree (for comparison against
+nNNNNNN in the table above), run:
+
+# git rev-list --count --first-parent HEAD
+
