FreeBSD 13.2R and OpenZFS bug #15933

REPOST -- OpenZFS bug number corrected -- David


freebsd-questions:


I have a FreeBSD with ZFS that I use as a CVS repository and Samba file 
server for my SOHO network.  I built it with ZFS-on-root on February 4, 
2020, using the FreeBSD installer:

     FreeBSD-12.1-RELEASE-amd64-memstick.img


I then added various packages via pkg(8), created a ZFS pool, migrated 
my data, and put the computer into service.  Over the years, I have used 
freebsd-update(8) and pkg(8) exclusively to install software, to update/ 
update the system, and to update/ upgrade the software packages.


I last successfully updated the system and packages on December 29, 
2023, prior to 12.4R EOL:

2023-12-29 20:46:54 toor@f3 ~
# freebsd-update fetch install
..
2023-12-29 20:48:42 toor@f3 ~
# pkg update
..
2023-12-29 20:49:45 toor@f3 ~
# pkg upgrade
..


This is the current system state:

2024-02-27 13:50:23 toor@f3 ~
# freebsd-version -kru
12.4-RELEASE-p9
12.4-RELEASE-p9
12.4-RELEASE-p9

2024-02-27 13:50:26 toor@f3 ~
# uname -a
FreeBSD f3.tracy.holgerdanske.com 12.4-RELEASE-p9 FreeBSD 
12.4-RELEASE-p9 GENERIC  amd64

# kldstat -m zfs
Id  Refs Name

Is there a way to determine the origin (e.g. Illumos, OpenZFS) and 
version of the ZFS code that is running in the kernel on the above 
computer other than downloading the source tarball and crawling the code?

I have been reading about OpenZFS data corruption bugs since November 
2023 and delaying upgrading this and my other FreeBSD computers.  I 
thought I had found an solution with FreeBSD 13.2R:

But, another OpenZFS data corruption bug report was opened yesterday for 
the current version of OpenZFS (2.2.3):

https://github.com/openzfs/zfs/issues/15933


Does this new OpenZFS bug #15933 affect FreeBSD 13.2R?
