This errata document for FreeBSD 12.2-RELEASE will be maintained until the release of FreeBSD 12.3-RELEASE.

This errata document contains "late-breaking news" about FreeBSD 12.2-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release.

[2020-10-27] A regression in ipfw(8) was discovered where packets are not properly forwarded with multiple IP addresses bound to the same interface.

This issue had been corrected in FreeBSD-EN-20:21.ipfw.

See PR 250434 for additional details.

[2020-10-27] A regression with zfs(8) send/recv was discovered where ZFS snapshots are not properly deleted under certain conditions.

An Errata Notice is planned for 12.2-RELEASE.

See PR 249438 for additional details.

[2020-10-27] A regression was discovered with the FreeBSD/armv7 BEAGLEBONE images where SD card I/O takes an excessive amount of time. As such, there are no BEAGLEBONE images for this release.

[2020-10-27] A very late issue was discovered with the x11/gdm package included on the amd64 and i386 DVD installer which causes GDM to fail to start properly.

Those installing GNOME as a new installation from the DVD should upgrade x11/gdm from the upstream pkg(8) mirrors after installation.

Those installing GNOME on a new installation from the upstream pkg(8) mirrors, or upgrading from a previous FreeBSD release should not experience any issues.

[2020-11-11] Due to slight changes to the ABI and KBI between FreeBSD 12.1 and FreeBSD 12.2, it is important to note that certain third-party kernel modules may need to be rebuilt locally, until FreeBSD 12.1 reaches end of life.

Of note, this includes, but is not limited to, graphics/*-kmod, net/*-kmod, and possibly others that are too extensive to list.
