16:05:51 <meskio[mds]> hi everyone!
16:05:52 <onyinyang> hihi :)
16:05:54 <cohosh> hi!
16:06:01 <meskio[mds]> here is our meeting pad: https://pad.riseup.net/p/r.9574e996bb9c0266213d38b91b56c469
16:06:01 <meskio[mds]> ask me in private to give you the link of the pad to be able to edit it if you don't have it
16:06:01 <meskio[mds]> I'll wait few minutes for everybody to add you've been working on and put items on the agenda
16:06:29 <Shelikhoo[mds]> hi~
16:08:07 <meskio[mds]> I think the only new discussion point is the go version bump
16:08:11 <meskio[mds]> I'll remove the others
16:08:28 <meskio[mds]> but let me know if you want to discuss any of them I'll bring them back
16:09:09 <theodorsm> That is from me
16:09:41 <theodorsm> Is there anything stopping us to upgrade to v1.24?
16:10:01 <meskio[mds]> yes, Tor Browser
16:10:20 <meskio[mds]> TB is still supporting some old versions of windows that doesn't have go 1.24
16:10:43 <Shelikhoo[mds]> I think it is maybe.. some macos?
16:10:56 <theodorsm> There is a new version of the pion stack including a security fix for dtls and a performance increase for webrtc
16:11:11 <theodorsm> However, they require a version bump
16:11:19 <Shelikhoo[mds]> https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/blob/809f72b82a856836540b31a7698544f0ef8a3198/projects/go/config#L52
16:11:54 <meskio[mds]> ahh, or maybe was macos
16:12:13 <meskio[mds]> we can bump the go version of everything except the client
16:13:35 <meskio[mds]> the next major release of TB might remove this limitation
16:13:43 <meskio[mds]> I think is in march
16:14:04 <meskio[mds]> morgan, pierv: do you know if the go version pin might be lifted in the next TB release?
16:14:16 <Shelikhoo[mds]> yeah... I think we wants to eventually upgrade the version
16:14:26 <meskio[mds]> pierov: -^
16:14:35 <Shelikhoo[mds]> we should make a release now, and then increase the go toolchain version
16:15:01 <Shelikhoo[mds]> if we know we are going ditch legacy golang version soon
16:15:29 <Shelikhoo[mds]> there is quite a few dependencies upgrades blocked by this legacy golang version
16:15:44 <meskio[mds]> mmm, pierov is not in this room and morgan is morganava :)
16:16:38 <unic3rn> hi
16:16:52 <meskio[mds]> hello
16:17:38 <meskio[mds]> theodorsm: do you think is ok if we hold this upgrade a couple of months?
16:19:02 <theodorsm> The security fix is regarding the GCM cipher suites. Mostly relevant for really longed lived DTLS sessions.
16:20:04 <meskio[mds]> does it affect both client and server?
16:20:11 <meskio[mds]> I mean client and proxy
16:20:22 <meskio[mds]> as proxies seem to be always the client in DTLS...
16:20:24 <theodorsm> Yes
16:21:09 <meskio[mds]> because is "easy" to upgrade the proxy, but the client will require either backport it or stop supporting snowflake in some versions of TB
16:22:36 <theodorsm> I could manually backport the dtls library and we could reference a commit meanwhile
16:22:43 <theodorsm> Might be possible
16:24:03 <Shelikhoo[mds]> or we can ask the tor browser(application team) about the browser version bump timeline
16:24:12 <Shelikhoo[mds]> before commit to an course of action
16:25:27 <meskio[mds]> I agree
16:26:09 <meskio[mds]> I can poke them and bring what they say to the existing MR
16:26:18 <theodorsm> Oki, then let's wait. We might release a backport at pion without a version bump
16:27:39 <theodorsm> EOF
16:28:19 <meskio[mds]> mmm, I thought there was a MR for this
16:28:20 <meskio[mds]> or an issue, I guess I imagined it
16:28:57 <theodorsm> https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/662O
16:29:08 <theodorsm> But that's not for go version bump
16:29:08 <meskio[mds]> this one: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/662
16:29:18 <meskio[mds]> thanks, I'm slow today
16:31:28 <meskio[mds]> I see, it doesn't include a version bump
16:31:40 <meskio[mds]> but it does upgrade dtls, I guess this is why the CI is broken...
16:32:07 <meskio[mds]> anyway I'll reply there
16:32:31 <meskio[mds]> anything else on this topic?
16:32:31 <theodorsm> The dtls version in the MR is retracted due to a bug, the new fix requires the go version bump
16:32:40 <theodorsm> EOF
16:32:47 <meskio[mds]> ok
16:32:50 <meskio[mds]> any other topics to discuss today?
16:33:19 <Shelikhoo[mds]> EOF from me
16:33:23 <meskio[mds]> we have few interesting links
16:33:24 <meskio[mds]> a
16:33:37 <meskio[mds]> a reminder that next thursday is foci just after this meeting
16:33:47 <meskio[mds]> and you want to attend you should register
16:33:53 <meskio[mds]> https://foci.community/
16:34:22 <meskio[mds]> and a cool visualization of snowflake proxies by ahf: https://ahf.me/snowflake/
16:34:27 <meskio[mds]> anything else for today?
16:34:47 <Shelikhoo[mds]> no from me
16:34:49 <onyinyang> not from me
16:34:55 <unic3rn> A, there was a question on the forum asking if the snowflake network is overloaded, still
16:35:17 <meskio[mds]> AFAIK is not anymore
16:35:20 <meskio[mds]> or not that much
16:35:26 <meskio[mds]> since 5 days, I think
16:35:38 <meskio[mds]> our metrics don't display anymore clients being denied
16:35:52 <cohosh> can you share a quick link to the forum post? i can reply with a screenshot from grafana
16:35:58 <cohosh> or i can find it after the meeting too :)
16:36:08 <meskio[mds]> I would say since Feb 7 or 8 is way better
16:36:14 <unic3rn> Ok. https://forum.torproject.org/t/call-for-more-snowflake-proxies/21213
16:36:16 <cohosh> yeah, we're not seeing clients getting turned away for lack of proxies at the moment
16:36:21 <cohosh> unic3rn: thanks!
16:36:38 <meskio[mds]> there is a big increase on snowlfake proxies answering our call for more
16:36:49 <meskio[mds]> and it looks like this has improved the situation
16:37:08 <meskio[mds]> because it looks like there is still a lot of people using snowflake
16:37:54 <unic3rn> great, eof from me.
16:38:08 <meskio[mds]> thank you for bringing it
16:38:41 <meskio[mds]> I guess I can close the meeting now
