I. Background The Unix File System (UFS) is one of several filesystems available on FreeBSD. UFS supports several optimization features, such as soft updates and journaling, both of which keep track of filesystem metadata to ensure a consistent state in the event of a crash or power failure. II. Problem Description When the root filesystem is configured with soft updates and journaling both enabled, which is the default for FreeBSD 10.1-RELEASE installations, the system may deadlock after a source-based or binary upgrade when the init(8) binary is replaced. The deadlock occurs when issuing reboot(8) or shutdown(8), after which the system becomes unresponsive when syncing the filesystem. III. Impact When the deadlock occurs, a hard system reset or power cycle may be required. IV. Workaround Systems that do not have soft updates and journaling enabled on a UFS root filesystem are unaffected. It is possible to work around the issue by waiting before issuing reboot(8) or shutdown(8) after upgrading the userland. It has been observed that deferring the reboot(8) for a period of 60 seconds to be sufficient. It is encouraged to issue several sync(8) commands during this period, to help ensure the filesystem writes have completed. Additionally, disabling soft update journaling on the root filesystem can also work around the issue. V. Solution Perform one of the following: 1) Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 2) To update your present system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 3) To update your present 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-15:05/ufs.patch # fetch https://security.FreeBSD.org/patches/EN-15:05/ufs.patch.asc # gpg --verify ufs.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.

I. Background The freebsd-update(8) utility is used to apply binary patches to FreeBSD systems installed from official release images, as an alternative to rebuilding from source. A freebsd-update(8) build server generates the signed update packages, consisting of an index of files and directories with checksums before the update, a set of binary patches, and an index of files and directories with checksums after the update. The client downloads the indexes, verifies the signatures and checksums, then downloads and applies the required patches. II. Problem Description Binary upgrades using the freebsd-update(8) utility consist of several invocations of the freebsd-update(8) utility itself. Each invocation performs a different task that depends on the previous invocation being successfully completed. If an upgrade is not thoroughly completed, it is possible for the freebsd-update(8) utility to download a subsequent patchset to a system with an inconsistent userland and/or kernel. In the case of such an incomplete upgrade, the freebsd-update(8) utility may incorrectly evaluate the running userland and/or kernel, which can cause binary patches to be incorrectly applied. In some situations, it is possible for patches to be applied for the incorrect FreeBSD version. III. Impact If incorrect patches are applied to the system as a result of a previous incomplete upgrade, it is possible that some system services may fail to start after rebooting the system, such as if the service is started by an executable that depends on a shared library that has been relocated as part of the upgrade. IV. Workaround No workaround is available, but systems that do not use FreeBSD-provided binary updates to upgrade are not affected. V. Solution Perform one of the following: 1) Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. 2) To update your present system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 3) To update your present 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.
