Title:
[5.8] broadcom driver binaries do not contain a driver string
Status in linux package in Ubuntu:
Incomplete
Bug description:
Brodcom network drivers in 5.8 do not have a version string (even
though it is present in the source code) modinfo cannot return a
driver version.
In a vm I installed 20.04.1 and then installed
linux-image-generic-hwe-20.04-edge from the Groovy archive to get the 20.04.2
HWE image (5.8) since you said 20.10 fails.
So this gives me the 20.04 userspace with a working modinfo, and a 5.8 kernel
which you've noted has failed drivers.
I am able to easily recreate this issue:
bladernr@vm1:$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal
bladernr@vm1:/$ uname -r
5.4.0-47-generic
bladernr@vm1:$ for x in b44 bnx2 bnx2x bnxt_en cnic genet tg3; do echo "$x:
`modinfo -F version $x`"; done
b44: 2.0
bnx2: 2.2.6
bnx2x: 1.713.36-0
bnxt_en: 1.10.0
cnic: 2.5.22
genet:
tg3: 3.137
Next, I installed the 5.8 kernel on 20.04.1 and tried the same
experiment (did it this way to ensure I was using the same userspace
and version of kmod that does work with 5.4):
bladernr@vm1:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal
bladernr@vm1:~$ uname -r
5.8.0-20-generic
bladernr@vm1:~$ for x in b44 bnx2 bnx2x bnxt_en cnic genet tg3; do echo "$x:
`modinfo -F version $x`"; done
b44:
bnx2:
bnx2x:
bnxt_en:
cnic: 2.5.22
genet:
tg3:
Note that now none of the driver versions are returned when probing
with modinfo.
Just grabbing one at random, bnxt_en, notice that the test strings in the
compiled driver for 5.4 include a version string, which is absent in the 5.8
version:

And looking at the source for bnxt_hst.h in both Focal (5.4) and
Groovy (5.8), the version strings appear to exist:
