| lynxis | How do you release kernel versions? Is there a written process about it? I've a regression in 16.04/xenial which was introduced in the upstream stable 4.4.x, but also fixed later in upstream and wonder how long I've to wait to be settled down into linux-image-4.4. | 16:15 |
|---|---|---|
| sarnold | lynxis: the dates for the sru cycle are on https://kernel.ubuntu.com/ and you can see the progress per package on https://kernel.ubuntu.com/sru/dashboards/web/kernel-stable-board.html | 18:51 |

| mathnewb | hi. i am new to kernel development. i am compiling focal using the master branch here: git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal and i notice that the master branch is at version 5.4.41, while a fresh install of the focal release image is at version 5.4.44. Why the discrepancy? | 22:34 |
| mathnewb | Or am I reading it wrong? Sorry. I am learning. | 22:35 |
| cascardo | mathnewb: the master branch is outdated, possibly some tooling or process problem. but don't confuse corresponding upstream stable releases and our ABI versioning | 23:14 |
| cascardo | so, we release a package that is versioned like 5.4.0-40.44 | 23:14 |
| cascardo | the important bit here is 5.4.0 and -40, ignore the .44 after -40, which we call upload number and increase for every upload, trying to couple with the ABI, which is -40 | 23:15 |
| cascardo | unfortunately, to add some confusion, that kernel has mostly all patches that are included in upstream 5.4.44 | 23:16 |
| cascardo | the version that is included in the ISO would be 5.4.0-26, with upstream patches up to 5.4.30 | 23:16 |
| cascardo | mathnewb: does it make sense? | 23:16 |
| mathnewb | cascardo: I was just eating some dinner. Thank you for writing back. I will read it now. | 23:36 |
| mathnewb | Ok. I think it makes sense, yes. In my VM (which I updated to latest after installing) a `uname -r` returns `5.4.0-40-generic`. the master branch is outdated, and building it gives me linux-*-5.4.0-39-generic*, which I believe squares with your explanation (master is slightly out of date). | 23:41 |
| mathnewb | and if I am understanding correctly, there is no exact "1-1" correspondence between an upstream ("mainline"?) kernel and an ubuntu release | 23:43 |
| mathnewb | the upload number just happens to coincide at the moment | 23:43 |
| mathnewb | (which tricked me into thinking there was a relation there that doesn't exist) | 23:44 |
| mathnewb | Does that seem correct? | 23:44 |
| sarnold | it's certainly confused me in the past :) | 23:44 |
| mathnewb | Haha, I'm glad I am not the only one! | 23:47 |
