FreeBSD 15.0-RELEASE Errata

Abstract

This document lists errata items for FreeBSD 15.0-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 15.0-RELEASE will be maintained until the release of FreeBSD 15.1-RELEASE.

Introduction

This errata document contains "late-breaking news" about FreeBSD 15.0-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release.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.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 15-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.FreeBSD.org/security/.

Open Issues

  1. ipfw(8) denies networking when booting a 15.0 kernel with 14.3 userland
    Workaround: disable ipfw(8) or upgrade completely before rebooting ipfw(8) systems
    State: open - https://bugs.freebsd.org/291562

  2. devinfo(8) output format accidentally changed
    Workaround: users parsing devinfo(8) must build it from a newer source
    State: reverted in FreeBSD 15.0-RELEASE-p2 - https://www.FreeBSD.org/security/advisories/FreeBSD-EN-26:01.devinfo.asc

  3. pkgbase(7) system upgrading from 14.3 to 15.0 is not supported
    Workaround: systems installed with pkgbase(7) must backup and reinstall
    State: works as intended, pkgbase(7) is an experimental preview

  4. FreeBSD/powerpc images do not boot on Apple G5 systems
    Workaround: do not install this release on Apple G5 systems
    State: fixed in main - https://bugs.freebsd.org/292341

  5. loader.efi(8) has a regression preventing boot on some systems with remote serial console facilities including HPE systems
    Workaround: unset hw.uart.console at the loader(8) prompt if it hangs and/or instant reboots when loading the kernel
    State: fixed in main - https://bugs.freebsd.org/291461
