Dialogic ISDN card vendor-driver kernel-module fails to load after meltdown/spectre kernel versions were released

[Michael]

Hey everyone,

did a brief evaluation of the problem in #ubuntu-kernel with user "klebers".
Also failed to find appropriate matches during a quick search in the filed bug-reports here.

Could really need some help on this one :)

### Problem description:

One of my linux machines running 14.04 in 32bit is having problems loading isdn-card drivers which are built from the drivers package available from the manufacturer (Dialogic).
The problems started since we upgraded the kernel to 3.13.0-139-generic, same for ...141-generic. It was working fine for years up to 3.13.0-137-generic.
I tried 3 different versions of this drivers-package, including the latest Diva4Linux_installer_9.6-117-162.bin (released in early 2017, see URL section at the end).

In our setup the machine normally loads 6 modules of this diva-suite in orchestration, one of them fails to load with a segmentation fault.
I disabled all of the startup routines and then tested the module loads manually.

Not sure if the cause of the problem lies within the drivers software, but for sure it started to be a problem with the meltdown/spectre changes in early january 2018.
I would really appreciate your help and input on the problem. Kind of lost at the moment... :/

Will try to raise a support ticket at the hardware vendor too.

### Manufacturer URLs:

The cards are "Dialogic Corporation Diva PRI/E1-30 PCI(e) v3", which may be looked up here
https://www.dialogic.com/diva-e1t1-pri-isdn

Diva System Release is available for download here
https://www.dialogic.com/diva-for-linux

NOTE: Just recognized, when preparing the URLs for this ticket:
There is a notification popping up saying that the Diva Card Product Series were shifted to a company called Sangoma Technologies by mid of Jan 2018, but the download does still work.
In the meantime I will try and figure out if there is more recent software available at Sangoma Technologies and update my results here.

Thanks for having a look into this

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hey Joseph, thanks for the update and having a look into this. :)

Did that, but while trying to build the driver modules using the upstream 4.15 kernel I stumbled upon something I have not noticed before.

The involved build script does not print all gcc lines to STDOUT. Only some errors are really reported in the overlay dialogue which printed to STDOUT instead..... This leads to wrong conclusions >_<

Once I recognized that and checked the full logs for more details, it revealed some problems that I was not aware of before.

Let me check on that and report back, I get the impression this bug-report was a false positive.

[Michael (mhzlp)]

Ok, done for the moment. Loading of modules is working as far as i can tell. Didn't reconnect the machine to the ISDN lines yet, but I dont expect problems here - at least not the reported one.

My mistake was, that I relied on the output of the vendor supplied wizard script too much.
They did not report all errors occurring during the build process.

The scripts were using a symlink without re-evaluating it, for as long as it is working...

To stay backwards compatbible, I did not remove some older kernels during the meltdown/spectre upgrade phase and thats were the problems started.... Wrong header files were used by the scripts.

Sorry, sometimes you just don't see it..

[Michael (mhzlp)]

Changed status to "invalid", is there anything else necessary for me to do?
