sysdig 0.8.0-1 ADT test failure with linux-hwe 4.10.0-27.30~16.04.2

[Andy Whitcroft]

SRU REQUEST [Xenial]

[Impact]

With Xenial HWE 4.10 kernels we see sysdig dkms package build failures because we are missing compat fixes for 4.10 with the Xenial sysdig dkms modules.

The fix is a minimal backport of missing compat changes to the driver, namely sysdig upstream commits:

    - [39ac26] Fix compilation issues with kernel 4.9 (#684)
    - [68823f] Ifdef __access_remote_vm since the function was made
               publicly accessible (#711)
    - [bf396c] Support for updated cpu hotplug API in 4.10
               kernel (#744)

[Test Case]

Install sysdig and sysdig-dkms. This should build the dkms modules correctly without failure. Next, one should be able to run the following command and gather sysdig events without problem:

sudo sysdig

[Regression Potential]
This could possibly break kernel combinations that we have not tested between 4.8 and 4.10. I have tested this with 4.4.0-83, 4.8.0-58 and also 4.10.0-26. The failure to build will mean that sysdig won't work on kernels we may not support.

Hello Andy, or anyone else affected,

Accepted sysdig into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/sysdig/0.8.0-1ubuntu1 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 and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. 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!

Installed Xenial, tested updated sysdig with 4.4.0-72 - works OK. Installed HWE kernel 4.10.0-27, tested with updated systed - works OK too.

Marking as validated.
