| pent1ckel | I'm using Ubuntu18 together with Strongswan and figured out that there is a memoryleak which is solved in mainline kernel already: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=86c6739eda7d2a03f2db30cbee67a5fb81afa8ba | 12:10 |
|---|---|---|
| pent1ckel | my question is: how to get this patch backported to supported Ubuntu18 kernels | 12:10 |
| apw | pent1ckel, i assume you mean 18.04 | 12:10 |
| pent1ckel | I'm sorry. yes I meant 18.04 apw | 12:11 |
| apw | pent1ckel, that sounds like the sort of thing which might come to us via stable; /me looks to see if it is pending | 12:12 |
| pent1ckel | so it is very new I would say | 12:12 |
| apw | it is a few weeks old, so there is hope | 12:13 |
| apw | pent1ckel, no not made it to stable; so to get it into ubuntu more agressivly you should file a bug | 12:20 |
| apw | against the kernel (https://bugs.launchpad.net/ubuntu/+source/linux/+filebug) | 12:20 |
| apw | and add the detail of the commit which fixes it and which series are affected | 12:20 |
| apw | and let us know here the # | 12:20 |
| pent1ckel | ok. so I will first verify this agains ubuntu kernel by my self (tested already with vanilla kernel) and created this bug with all information included | 12:21 |
| apw | pent1ckel, thanks | 12:21 |
| pent1ckel | apw: is there a list where I also could have searched for this patch and the current state? | 12:22 |
| apw | pent1ckel, the stable tree is where i looked to see if it was going to be coming soon | 12:22 |
| apw | pent1ckel, as it is not, it really is only in linus' tree | 12:22 |
| pent1ckel | it is in mainline as well. I've downloaded 5.4.0 and it is there | 12:24 |
| pent1ckel | or did I understood you wrong? | 12:24 |
| apw | pent1ckel, the bug is present ? | 12:24 |
| apw | or the fix is present | 12:24 |
| apw | the fix is present in 5.4-rc8 i think i saw | 12:25 |
| pent1ckel | https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/net/xfrm/xfrm_state.c?id=v5.4&id2=v5.3 | 12:25 |
| pent1ckel | here it is | 12:25 |
| apw | right it is in only in linus' tree at this time; it has not made it to the stables yet | 12:26 |
| apw | which is why we are talking about a bug | 12:26 |
| pent1ckel | just to understand: https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.4.tar.xz this is not stable? there it is included | 12:27 |
| apw | that is not a kernl produced by the upstream stable team | 12:28 |
| pent1ckel | ohhh | 12:28 |
| apw | it is a final version of the development kernel | 12:28 |
| pent1ckel | ok. I'm sorry. this is new to me | 12:28 |
| apw | it will be the kernel in our devleopment release soon | 12:28 |
| pent1ckel | understand. I will verify and file the bug | 12:28 |
| apw | selected fixes from the primary kernel get backportedd and put out as updates to older upstream versions | 12:28 |
| apw | and we use those to see fixes for our kernels based on those versions | 12:29 |
| pent1ckel | sure ... it is caled mainline ... now I got it. sorry for misunderstanding | 12:29 |
| pent1ckel | I'm sorry. I nenver recognized this | 12:30 |
| apw | pent1ckel, no need to appologise, it is complex, and the relationships between the kernels produced by distros and upstream even more so | 12:30 |
| pent1ckel | apw: thank a lot. also I learned somethign new today | 12:31 |
| mcphail | Hello. I've had 2 lock-ups in the past week when using wireguard with ubuntu-mate 19.10. I have .crash files in /var/crash which don't seem to be being sent by apport despite me selecting "report problem". Should I post them somewhere? | 18:03 |
| === ben_r_ is now known as ben_r | ||
| apw | mcphail, there is a wireguard package in ubuntu you could file them against i guess | 20:26 |
| mcphail | apw: OK, will do. Wondered if the oops was useful to you guys. I wish I could work out how to trigger it again | 20:32 |
| apw | mcphail, the oops will always be key to solving that kind of thing i would think | 20:40 |
| mcphail | Ta. Have filed at https://bugs.launchpad.net/ubuntu/+source/wireguard/+bug/1854225 and temporarily marked as "private" due to the info about the null pointer dereference | 21:12 |
| ubot5 | Error: ubuntu bug 1854225 not found | 21:12 |
| apw | mcphail, could you subscribe launchpad user apw to it | 21:13 |
| mcphail | apw: done | 21:15 |
