Abstract

This document lists errata items for FreeBSD 13.0-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.

Introduction

This errata document contains "late-breaking news" about FreeBSD 13.0-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release.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 13-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

Late-Breaking News

[2021-04-05] A very late issue was discovered in the /usr/bin/dc program. The "P" command does not correctly pop the top of stack value and this will break complex scripts that continue after printing a result. The /usr/bin/bc program is not affected, since it does not depend on dc as its execution engine.

[2021-04-14] An issue was discovered where during an upgrade, when the kernel is new but /sbin/ifconfig is still the previous version, VLAN interfaces are configured with an invalid ethernet protocol type. This causes the VLAN interfaces to send invalid traffic, resulting in non-functional networking. Once the updated /sbin/ifconfig binary is installed, VLANs are created correctly. When depending on network access via VLANs during the upgrade, it is suggested to install the new world (run the second freebsd-update install) before rebooting.
