FreeBSD 14.3-RELEASE Errata

Abstract

This document lists errata items for FreeBSD 14.3-RELEASE, containing significant information discovered after the release or too late in the release cycle to be otherwise included in the release documentation. This information includes security advisories, as well as news relating to the software or documentation that could affect its operation or usability. An up-to-date version of this document should always be consulted before installing this version of FreeBSD.

This errata document for FreeBSD 14.3-RELEASE will be maintained until the release of FreeBSD 14.4-RELEASE.

Introduction

This errata document contains "late-breaking news" about FreeBSD 14.3-RELEASE. Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release. These other copies of the errata are located at https://www.nsoiwdjgsld.gq/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 14-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

For a list of all FreeBSD CERT security advisories, see https://www.nsoiwdjgsld.gq/security/.

Open Issues

  • When "restarting" the FreeBSD installation process, some values are remembered and not re-prompted.

  • The installer produces a non-booting system in the (non-default) combination of MBR and ZFS.

  • SCTP can use deprecated addresses even when net.inet6.ip6.use_deprecated is set to zero (non-default).

  • Unloading the snd_dummy kernel module can cause a kernel panic.

  • Some wifi drivers fail to connect to networks using the (long-deprecated) TKIP protocol.

Late-Breaking News

The ZFS raw virtual machine image for AMD64 is prone to kernel panics (bug 287482). FreeBSD-14.3-RELEASE-amd64-zfs.raw.xz has been removed from download.freebsd.org but remains available for reference on archive.freebsd.org. Torrents of the file should be avoided.
