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.
   ...
   < Unknown Type
   < Header and Data:
   ...
   > Firmware Inventory Information
   > Firmware Component Name: BMC Firmware
   ...
   < Type: <OUT OF SPEC>
   ---
   > Type: DDR5
   ...
   < Upgrade: <OUT OF SPEC>
   ---
   > Upgrade: Socket LGA4677
   ...
   < Unknown Type
   < Header and Data:
   ...
   > Firmware Inventory Information
   > Firmware Component Name: BIOS Firmware

[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.

[Original Description]

Backport the support for SMBIOS 3.4 and 3.5 specifications
in Ubuntu Kinetic (dmidecode 3.4) to Jammy (dmidecode 3.3)
to enable new hardware in the LTS release per SRU policy [1].

[Patchset Details]

Patches 1-8,10-11 are for SMBIOS 3.4;
Patches 9,12-14 are for SMBIOS 3.5;
Patch 15 updates supported version.

01: SMBIOS 3.4: add new codes/strings for memory device type
02: SMBIOS 3.4: add new codes/strings for processor socket
03: SMBIOS 3.4: add new codes/strings for slot characteristics
04: SMBIOS 3.4: add new codes/strings for memory device speed [string backward-compatible changes]
05: SMBIOS 3.4: add new codes/strings for slot types [changes append '(U.2)' to 'PCI Express {2,3} SFF-8639' per spec]
06: SMBIOS 3.4: add new codes/strings for processor characteristics
07: SMBIOS 3.4: fix for patches 5-6
08: SMBIOS 3.4: add support for ARM64 Processor ID field based on arch call [string backward-compatible changes]

09: SMBIOS 3.5: add new codes/strings for processor socket
10: SMBIOS 3.4* prep for patch 11 [string backward-compatible changes]
11: SMBIOS 3.4* add new codes/strings for slot types [string backward-compatible changes]
12: SMBIOS 3.5: add new codes/strings for manufacturing mode, pointing devices, onboard devices; introduce slot height
13: SMBIOS 3.5: introduce firmware inventory information (characteristics, state, components
14: SMBIOS 3.5: add new codes/strings for dmi types
15: SMBIOS 3.5: set suppported smbios version to 3.5 (straight from 3.3)

Hello Mauricio, or anyone else affected,

Accepted dmidecode into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/dmidecode/3.3-3ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Verification done on jammy-proposed.

1) a system/hardware vendor tested and confirmed that:
   - systems with SMBIOS 3.5 report the new fields as expected;
   - systems with SMBIOS < 3.4 keep the old fields as expected.

2) I tested on several physical and virtual machines, and:
   - systems with SMBIOS < 3.4 keep the old fields as expected.
     (see details below and in next comment.)

Physical machines:
- Supermicro AS -2024US-TRT
- Dell PowerEdge R730xd
