Background ZFS is one of several filesystems available on FreeBSD. ZFS supports many advanced features, including checksumming, transparent compression, and snapshots. File "holes" are used by filesystems to limit the amount of storage space occupied by a file containing long runs of zero bytes. Rather than filling disk blocks with zeroes, file metadata can indicate the extent of such a run and the filesystem hides the distinction from user applications. II. Problem Description When a file containing holes is mapped using mmap(2), mapped regions of the file may be ignored by lseek(2) when SEEK_HOLE or SEEK_DATA are passed as the "whence" parameter. III. Impact The bug may cause application misbehavior; the precise effects depend on the nature of the application triggering the bug. 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-22:11/zfs.patch # fetch https://security.FreeBSD.org/patches/EN-22:11/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 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 - ------------------------------------------------------------------------- stable/13/ 3aa1cabca37d stable/13-n248633 releng/13.0/ 210991b1f28b releng/13.0-n244787 - ------------------------------------------------------------------------- Run the following command to see which files were modified by a particular commit: # git show --stat Or visit the following URL, replacing NNNNNN with the hash: 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 VII.
