#ls2 (irc2p) | #ls2 I2P Protocol Development Discussion - Next Meeting Monday, October 9th 6:30 UTC

zzz we "blame" peers when no response. it could be that tunnel or the reply tunnel, we add them up and say, 33% blame to him, 15% to her, 50% to that guy, etc

zzz so that all goes into the profile

zzz we do not ban a router for that, I think it's a vulnerability to do so. drz was doing that and I talked him out of it

dr|z3d orignal: I do, but I have a much more generous allowance for requests than zzz.

dr|z3d I barely see any bans these days.

orignal I mean not router but tunnel build coming from it

orignal see what happend

zzz yes we only any router to be in 3% max of participating tunnels (more or less)

orignal low active router expecially firewalled has much better rate

orignal than high loaded router

orignal it simply means you punish routers for active particiaption

dr|z3d I think my rate is now at something like 15 (?) requests every 220s for slow routers, more for faster routers.

dr|z3d with a sliding scale based on overall percentage.

orignal zzz, not a problem with transit tunnels

zzz ok good

orignal the problem is own tunnels

orignal that an active router can't build tunnels

dr|z3d Haven't seen anything explictly banned in a while. Very rarely do requests get dropped.

zzz sure. in times of congestion, slow down tunnel build, don't speed up

zzz go down to 1 tunnel

orignal maybe you guys drop requests too often

zzz we're handling 50% more tunnels per router than back in November before this all started

zzz we can handle it

orignal as result I will have to change my profiler to bypass routers that don't let me build my tunnels

dr|z3d any theory on the asymmetric traffic, zzz? it's sometimes pretty pronounced.

orignal and if Java keeps droping but i2pd doesn't

zzz I still think it's tunnel builds from insane sam clients or i2pd routers, but it could also be i2p plus infinite loops or bugs

orignal it will endup that i2pd build tunnels through other i2pd only

orignal also I see not extra transit on ygg-only routers

zzz yeah we don't want to segment the network into two parts

zzz it's just going to take some time to work out

zzz anyway, what should I tell bitcoin?

orignal and since Java never selects ygg-only routers for tunnels

orignal you should tell there is nothing to do with them

dr|z3d orignal: that's always a good idea.

dr|z3d if you get repeated rejects from a router, assume it's either overloaded or doesn't like you and avoid it for a while, don't keep sending requests.

orignal also I saw sormycloud's tweet that he has bandwidth issue

zzz yeah I think I have to say that, sorry if the GH issue sounded panicky, we're smarter now, probably not bitcoin

orignal dr|z3d but it will endup with split queicly

orignal zzz, ofc no

zzz stormy is running i2p plus and I think is vulnerable to several nasty bugs

orignal the way how they implemented is shitty

orignal and they should fix this issue regardless

zzz right orignal we want to encourage them to fix it, they are doing that

zzz agreed

orignal aboyt strormy

orignal if he has bandwidth issue

orignal maybe too many people use i2p as tor

zzz ok that will be my message, I'll put it in the GH issue later this week

zzz anything else on 1) ?

dr|z3d not that, orignal

zzz go ahead about stormy

dr|z3d outproxy traffic is what you'd consider normal.

dr|z3d if anything, the issue is probably Tor itself and the ongoing DDOS.

orignal however

orignal is it possible that bunch of people use i2p instead tor?

dr|z3d we did see some huge usage on one of the outproxy routers before Xmas.

orignal expecially from Russia

dr|z3d but that wasn't outproxy traffic.

orignal so would be nice what stormy says

zzz I've also added outproxy warnings to our bittorrent and embedding guides

dr|z3d I'm just talking to him. He just wants faster is all. Doesn't sound like an issue as such. grumbling about needing a 10Gb pipe.

zzz it's not directly related to request rejects

orignal fine for me

eyedeekay I don't have any other concerns you haven't been able to address

zzz other than to avoid getting there

zzz a couple issues with implementation:

zzz a) I can't enable it now or we find all the dev build routers

dr|z3d and if I'm publishing a "high loaded, avoid" cap and you're still pushing requests my way, then you're probably up to no good if you known about the caps, no?

zzz b) I don't really want to do the profile-update side of it until a lot of routers support it

zzz so I think what I want to do is: Flip a switch to turn it on after our next release is out

dr|z3d re a) just do what you've done for the simple stats, zzz.

zzz and then do the profile-handling part of it in the release after that (July)

orignal fine

zzz I'll put one router up now that will publish it, since it's in a dev router family anyway

dr|z3d if local.version < 0.9.58, don't enable. that's the basic logic, orignal

zzz we good with D/E/G or anybody want to spend a week arguing about it? :)

orignal so should I add code just to recognize them?

orignal why? If see such code it means I can use it

dr|z3d D E G seems fine, no sense bikeshedding.

zzz you can if you want orignal, I'm worried about adding a bug that would avoid everybody and break things

zzz so I may recognize it but not do too much with it

orignal I mean just to not produce log message if I see such unknown code

zzz that's the hardest part, if everybody publishes E, don't break

zzz sure

zzz thats fine

zzz I'll put up my router with it tomorrow

zzz and I'll put this into a proposal, which will be 162

zzz anything else on 2) ?

orignal ok. 162

orignal no

zzz 3) new proposals

zzz so I have three stubbed out and loaded up

zzz 162) congestion caps

zzz 163) Datagram2, to fix the signature issues from back in the LS2 proposal

zzz 164) Just a stub, it's the issue I'm working on privately with orignal, will make it public later

orignal good point

zzz and I'm awaiting to test that fix with you when you get to it, no rush

orignal yes I will implement 164 soon

orignal also what do you guys think about quic instead streaming?

zzz so I'm putting them all on the website, but 164 will only say 'streaming', thats it, nothing else

zzz SSU2 nearly killed me, let's not do it again :)

orignal I should

orignal because streaming becomes a bottleneck now

zzz anything else on 3) ?

zzz maybe it just needs some tune-ups/tweaks/fixes

orignal I plan to implement UDP socks proxy

zzz client-side you mean?

orignal no, streaming alsways use one tunnel rather than all available

orignal yes, client proxy

zzz oh, that's the multipath TCP stuff, that's really hard, I looked at it once

orignal you meantione you have it already

zzz right

zzz anyway

zzz anything else on 3) ?

orignal no

zzz 4) two LS from postman

zzz I spent about 15 minutes looking at it on stats.i2p which has a similar setup and looking at logs

zzz didn't see anything wrong

zzz all looked fine and only got one LS from stats

zzz I'm awaiting an answer from postman on whether he's on the i2p plus platform or not

orignal I can tell you more

zzz once I get the answer, I'll either forward that info to dr|z3d or dig into it more myself

orignal postman always sends back wrong one

orignal and I have to re-request it from floodfill

zzz that makes sense

orignal hence get disconnects from Irc2P too often

zzz yeah that doesn't help

zzz not a bad problem, but not great either

dr|z3d related, being able to expire leasesets locally before they're expired, to force an update.. worth thinking about?

zzz so when I hear from postman we'll move forward

zzz dunno what you're trying to accomplish with that

zzz anything else on 4) ?

dr|z3d a nicer way of requesting a new lease than restarting the client tunnel is what I'd hope to accomplish.

zzz well you could put a delete button on the console I guess

orignal that's what we do now

dr|z3d yeah, that's kinda what I'm driving at, zzz.

orignal no

zzz have fun

zzz ok, next meeting in one week or two?

dr|z3d delete remote lease, or delete all remote leases. :)

orignal 2

zzz ok, Feb. 6

zzz thanks everybody

dr|z3d fwiw, zzz, while I'm still trying to work out the stackoverflow bug, for now I've backed out a chunk of the ISJ mods.

zzz nice

dr|z3d so we'll see if that helps anything.

zzz I'm thinking of a more structured way to try to convince you of where you've gotten in the weeds, without the pain or time of a code review

zzz maybe next week

dr|z3d I'm still varying concurrency and timeouts based on a bunch of criteria, but otherwise, everything else is as canon.

dr|z3d when I've confirmed it's not breaking stuff I'll commit it and invite you to check it's more sane :)

zzz you're not grasping how deep down in the router you are in ISJ or what the rules are when you're there

zzz and you're probably doing it elsewhere

zzz OOMs, heisenbugs hard to reproduce, network spam, or problems in unrelated areas could be the result

dr|z3d sure, can't argue.

dr|z3d ok, this patch seems fine on a few routers, no obvious epic fail happening. let me commit it.

zzz well, your mods are not (at all) functioning as intended, so they weren't well tested, and rest assured there's no downside to ripping them back out :)

dr|z3d gitlab.com/i2pplus/I2P.Plus/-/commit/be496677353e9148fb621878a02971188d8551ef

weko Tunnel creation success rate: 22%

weko Looks bad

dr|z3d I have mixed results on various routers. one is 55%

weko Client Tunnels: 295 (I haved 220 some days ago)

zzz that change is insufficient, as you've left in near-identical borked code in the constructor that was implicated in the stack overflow last week, but now I'm just repeating myself and I can't be your code review guy

weko My router always have >9000 tunnels

weko zzz: are you really working on multipath streaming? I guess оrignal suggest you, I am right?

dr|z3d boolean uninteresting the problematic section, zzz?

dr|z3d oversight if it is, I meant to remove that.

zzz so no, it's not all as in canon

zzz your constructor mods were directly in the path of the stack overflow last week, check the logs, and if it happened once I bet it's happening to lots of people

zzz I don't know how you thought you fixed it last week but your code is still in there

dr|z3d gitlab.com/i2pplus/I2P.Plus/-/commit/4b4628aeb9c19fce37e232bbdecf3e70de432f09

zzz identify the loop, find out which of the steps is your mod, rip it out, that breaks the loop, that was my advice last week

dr|z3d if that doesn't fix it, I'm at a total loss as to what does.

zzz but my advice this week is rip it all out

dr|z3d aside from modifying concurrency and search timeouts, I have.

zzz I'm not even gonna look, that's all I got for now

dr|z3d if there's something obvious in the latest commit that's still not been addressed, I'd be happy to know what it is.

dr|z3d great. thanks. remind me to be equally elliptic when you need help :)
