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

eyedeekay Nobody push to gitlab for about 5 minutes.

zzz 0) Hi

zzz hi

zlatinb hi

orignal hi

zzz what's on the agenda for today?

orignal SSU2 introducers

eyedeekay hi

orignal and release results

zzz ok, 1) is SSU2 introducers

zzz 2) is release results

zzz I'll add 3) SSU2 development status

zzz anything else?

zlatinb yes, startup expl. tunnel build optimizations

zlatinb just want to check how i2pd does it really

zzz ok that's 4)

zzz one sec while I write it all down

zzz 1) SSU2 introducers

orignal so as I see we bulish the same keys but iHost and iPort

orignal because we want to take it from RI

zzz I'm already lost :(

orignal what fields do we publish in SSU2 address interoducers?

orignal iTag, iExp, iKey (or iIdent)

orignal and we don't publish iHost and iPort

zzz right. itag, iexp, and iIdent or maybe call it iRouterHash for now

zzz right, no ihost, no iport

zzz that's the proposal from last week

orignal yes, that's what I meant

orignal and we also agreed an RI might have two SSU2

orignal ipv4 and ipv6

zzz right

orignal and we take one from router's caps

orignal so if we see "4" we must use ipv4 adddress

zzz I _think_ so, but I haven't really thought that far

orignal I'm trying to write that code

orignal basically data structures

orignal beside it everything is clear

orignal so should we leave iKey or use another name?

zzz ok, but my head is full of "phase 1" and about to explode, so it's hard for me to help on phase 2 right now

zzz re: leave Ikey or not, I don't know

orignal phase2 is fine

orignal but I need to finish parser

zzz for now, I suggest you guess what is the best way to do it

orignal fine

zzz just remember that router infos are untrusted input from other users, don't ever die on missing/bad values, bad base64, bad lengths, etc.

zzz anything else on 1) ?

orignal no

zzz 2) release results

zzz about 23% of net updated

orignal do you see improvements?

zzz doesn't look like biglybt has updated yet

eyedeekay Anecdotally the Reddit crowd is pretty happy

zzz I think I see a little improvement, but of course I've been running with fixes for a month

zzz I just asked on zzz.i2p for feedback for people that did NOT run with any fixes a month ago

zzz I've had good luck talking to our gitlab in the last week

zzz eyedeekay, could you elaborate on the reddit consensus?

orignal improvement about failed tunnels of course

zlatinb I see big improvement in muwire

eyedeekay The reddit users who have contacted me have, in particular, noted improved reachability of popular sites, getting to sites in <=1 refreshes

zzz I don't have any tunnel fail data, but of course I've been running with the fixes for weeks

eyedeekay Much more acceptable behavior for browsing eepsites in general

orignal good to know

zlatinb the big improvement came suddenly when the old i2pds crashed

orignal that's what I mean

zzz my expl. build success chart is up from about 43% to 46%, but a little too soon to really know what the average is

orignal so most of i2pds are new now

zzz because there's variation on weekday vs. weekend

orignal Transit: 599.35 GiB (1800.96 KiB/s)

orignal I see more transit traffic than before and on all my nodes

zzz bottom line, all seems good so far

zzz anything else on 2) ?

zzz hi RN

orignal not from me

RN :)

zzz 3) SSU2 development status

zzz I guess I'll go first

orignal fine

orignal and tell me your idea to publish it as SSU ))

zzz I've checked in about 5000-6000 lines of code and comments and related changes

zzz since the release

zzz mostly untested and not hooked in yet

zzz the changes broke my test code in a few places and I'm fixing those now

zzz the bulk of the changes are now in and within a few days I'll be able to start testing on a testnet

zzz and fixing what's probably dozens of bugs

zzz I'm still ready to do testing with test code vs. i2pd whenever you're ready

orignal I'm not ready yet

zzz hope to have things working in the testnet in maybe a month

orignal so tell me how do I recognize if SSU address is SSU2?

zzz so, same as for NTCP: it will have a v=2, a s=.... and (if inbound) a i=...

orignal got it

zzz that's the end of my status, orignal how are you doing?

orignal so, I have implemented parsing of incoming packets

orignal first I try to decrypt first 8 bytes

orignal I calculate key using my own intro key for that address

orignal then I try to find session by connID in the table

zzz great, good start

orignal if it's not there I try to find it amoung pending session requests by endpoint where a packet comes from

orignal if still not found I assume it's new incming session

orignal that's all for now

zzz super, thanks for the update

zzz anything else on 3) ?

orignal from another side I develop code to support SSU2 address

orignal in my RI

orignal so I will start publishing it sson

orignal as SSU2 of course ))

zzz ok

orignal that's all

zzz 4) startup expl. tunnel build optimizations

zlatinb yes

zlatinb so I did some analysis and 75% of exploratory tunnels build in less than 500ms

zlatinb and the longest successful was about 2500ms

zlatinb right now java sets the timeout to 13 seconds. What is the timeout for tunnel build for i2pd?

orignal let me check

orignal const int TUNNEL_CREATION_TIMEOUT = 30; // 30 seconds

orignal so I delete pending tunnel after 30 sec

zlatinb how many exploratory tunnels are built in parallel on startup?

orignal depedning on config

orignal 3 by defualt

orignal for each side

zlatinb and how many tunnel build attempts are allowed in parallel?

orignal all tunnels of exploratory?

zlatinb exploratory

orignal as many as I need

orignal usually 3

orignal at the beginning

zlatinb ok thanks

zlatinb that's all from me, was just curious

zzz ok sounds like that's it for 4)

zzz anything else for the meeting?

orignal I also build cleint tunnels

orignal but each pool builds tunnels in random intervals

orignal to avoid spikes

orignal no

zzz didn't mean to cut you off, feel free to keep going

zzz but that's it for me

orignal if zlatinb has more questions

zzz thanks everybody

zlatinb no more questions thanks

orignal I hope nobody is going to ban Russian IP addresses?>

orignal since it's new hysteria

eyedeekay That would probably be self-defeating wouldn't it?

orignal I saw one idiot who banned Russian IPs on his yddsrasil node

orignal seriously

eyedeekay Bummer. Nobody with a brain has a problem with regular Russians.

eyedeekay This is clearly on Putin.
