It makes sense to continue over email. 09:10:01 <masashi910> pavel1: Thanks! 09:10:09 <masashi910> any other topics? 09:10:14 <masashi910> 3 09:10:18 <masashi910> 2 09:10:22 <masashi910> 1 09:10:25 <masashi910> #topic Kernel testing 09:10:37 <masashi910> patersonc: are you here? 09:11:14 <masashi910> So, let's skip this part this week. 09:11:16 <masashi910> #topic CIP Security 09:11:22 <masashi910> yoshidak[m]: the floor is yours. 09:11:25 <yoshidak[m]> hi 09:11:42 <yoshidak[m]> There is no major update from last week. 09:12:01 <yoshidak[m]> We hold the meeting w/ Exida tomorrow. 09:12:16 <yoshidak[m]> That's the end from me today. 09:12:27 <masashi910> yoshidak[m]: Thanks for your works! 09:12:40 <masashi910> any other topics? 09:12:48 <masashi910> 3 09:12:51 <masashi910> 2 09:12:55 <masashi910> 1 09:12:58 <masashi910> #topic AOB 09:13:37 <masashi910> Regarding the development start based on 5.10, it was announced with the following blog. 09:13:50 <masashi910> https://www.cip-project.org/blog/2020/12/02/cip-to-embark-on-kernel-5-10-development-for-slts 09:14:05 <masashi910> That's it from me. 09:14:14 <pavel1> So... 09:14:29 <masashi910> pavel1: Please. 09:14:38 <pavel1> Do we start preparations? 5.10.1 is likely to be huge. 09:14:51 <pavel1> As in -- lots of stuff to review. 09:15:08 <masashi910> pavel1: Yes, but after 5.10 is released. 09:15:26 <wens> IIRC -rt is not merged into mainline yet? 09:15:37 <pavel1> Alternatively, we could wait for say 5.10.5 before forking cip branch. 09:15:48 <iwamatsu> yes, it is not merge yet. 09:15:59 <pavel1> Major effect would be that we would not have reviewed 5.10 to 5.10.5 changes :-). 09:16:14 <pavel1> No, -rt is not yet merged into mainline in an usable way. 09:17:14 <masashi910> pavel1: I think we can choose the best timing. 09:17:39 <pavel1> Ok :-). 09:18:36 <masashi910> pavel1, iwamatsu, wens: Let's discuss about it in the future. :) 09:18:49 <iwamatsu> OK 09:19:35 <masashi910> pavel1: Do you have any insights on CVE-2020-28588 09:19:44 <masashi910> ? 09:20:17 <pavel1> It looks to me like vulnerable code is not in 4.4 or 4.19, but let me confirm. 09:20:24 <sudip> CVE-2020-28588 was introduced by 631b7abacd02 in v5.1 and that has not been backported so I dont think any CIP kernel is affected 09:20:26 <pavel1> If it is, it is easy to fix/backport. 09:21:16 <masashi910> sudip: Thanks for this info! 09:22:12 <wens> If it's a straightforward backport, I suppose we could still ask greg to include it for v5.4, as a way of showing the helpful side of CIP 09:23:07 <pavel1> wens: I'd let someone else do that. I'm pretty sure we are not the only ones watching CVEs. 09:23:12 <iwamatsu> Oh, this commit's comit date is CommitDate: Fri Apr 5 09:26:43 2019 -0400. but Auther date is Mon Nov 7 16:26:37 2016 -0500 09:23:13 <iwamatsu> . 09:23:48 <pavel1> wens: Or maybe we can/should do that if it is not fixed by january :-). 09:24:12 <wens> pavel1: fine with me. I suppose we might see bwh or some other distro guys asking for it. :) 09:24:46 <masashi910> So, shall we keep our eyes on this CVE, and decide what to do in the future? 09:25:04 <masashi910> I mean, make this as an AI. 09:25:27 <wens> Sure. Let's keep it until, say, mid-January? 09:25:43 <iwamatsu> +1 09:25:52 <pavel1> +1 09:26:02 <masashi910> Great! Thanks! 09:26:10 <masashi910> Any other topics? 09:26:27 <masashi910> If there are no topics, then, let's close the meeting. 09:26:34 <masashi910> #endmeeting
