[Trusty] iscsitarget-dkms 1.4.20.3+svn499-0ubuntu2.1 fails to build on linux-generic-lts-xenial kernel

[fmyoen]

[Impact]

 * The iscsitarget-dkms package was not updated to be compatible with the Xenial HWE stack (4.4 kernel) and the driver fails to build.

[Test Case]

 * Install iscsitarget-dkms. If it successfully builds and the module is loadable, the package is fixed.

[Regression Potential]

 * Given that the package currently does not function for the Xenial stack, I believe the regression potential is low. However, the one case would be breaking existing 3.13.x deployments of 14.04; in my testing, the DKMS package successfully builds there as well.

Thank you for reporting this bug! It seems we need to add/backport the Xenial changes for 4.3/4.4 compatibility. I'm working on that now.

[Nish Aravamudan (nacc)]

Hello, I have provided a build of iscsitarget at: https://launchpad.net/~nacc/+archive/ubuntu/lp1612627 which I believe has the correct fixes backported. If you could give it a test and report back the results, that would be great!

Thanks,
Nish

How long before the fix is available through repositories?

[Nish Aravamudan (nacc)]

@msa1: no one has reported back if the issue is fixed by testing my PPA, so no timeline until that is done.

[Nish Aravamudan (nacc)]

@msa1: I setup a VM and tested it and have uploaded the necessary fix for SRU.

Hello fmyoen, or anyone else affected,

Accepted iscsitarget into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/iscsitarget/1.4.20.3+svn499-0ubuntu2.2 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 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, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

Set up a 14.04.5 VM. Installed iscistarget-dkms from universe and got the build failure as described in this bug. Installed 1.4.20.3+svn499-0ubuntu2.2 from trusty-proposed and the modules successfully built.
