Title:
Support SMBIOS 3.4 and 3.5 in Jammy for Hardware Enablement
Status in dmidecode package in Ubuntu:
In Progress
Status in dmidecode source package in Jammy:
Invalid
Status in dmidecode source package in Kinetic:
In Progress
Bug description:
[Impact]
* Support the SMBIOS 3.4 and 3.5 specifications in Jammy
to enable new hardware in LTS release per SRU policy [1].
* Backport of 15 relatively simple patches from dmidecode 3.4
in Kinetic to dmidecode 3.3 in Jammy (vs. 49 for full version).
* Patches are detailed below.
[Test Plan]
* Check no regressions on current systems with SMBIOS < 3.4,
i.e., no output changes in text and binary form.
$ sudo dmidecode > old.txt 2>&1
$ sudo dmidecode --dump-bin old.bin
$ apt install dmidecode # modified package
$ sudo dmidecode > new.txt 2>&1
$ sudo dmidecode --dump-bin new.bin
$ cmp old.txt new.txt; echo $?
0
$ cmp old.bin new.bin; echo $?
0
* Check for expected output on new systems with SMBIOS >= 3.4.
$ diff old.txt new.txt
...
< # SMBIOS implementations newer than version 3.3.0 are not
< # fully supported by this version of dmidecode.

* Possibly perform synthetic testing with crafted C structures.
[Where problems could occur]
* Mostly the patches add support for new bits/codes/strings,
so there's no changes expected for the old spec support,
but some patches lightly change things a little bit (but
only one should change a string, as far as I could tell).
* So, theoretically, parsers that expect a very precise
and constant format/string might have issues *in case*
the changes introduced any. (But such tools maybe are
already using the binary form anyway, for more detail.)
[Other info]
* No additional fixes upstream to the included patches.
(The git repo's commits have the 'Fixes:' tag usage.)
There's only 2 more commits after dmidecode-3-4 now.
