zzz log-router-3.txt-java.security.GeneralSecurityException: No RI in Session Confirmed

orignal I mean AEAD

orignal no RI is SessionConfirmed?

orignal I will check

orignal just no RI block?

zzz thats right. session confirmed had only one block in it, not logged, maybe padding only?

zzz ummm here's a problem

zzz Router: gpUBQf-76CJFzCx7aIP2RuXFc7oUn3E0OCrydF8eqSo=

orignal what?

zzz nope, never mind, not that one

orignal I don't see this problem in my logs

zzz seen with YXEA and one other router

orignal questuin about SessionConfirmed

zzz BpAT is the other

orignal when you rettans what packet num do you use?

orignal 1 or 2?

zzz session confirmed is retransmitted as-is, packet number 0 always

zzz has to be that way, or else the mixhash() and key agreement would not work

orignal sorry I meeant nonce

orignal for part 1

orignal do you know what was his RI lenght?

zzz everything is exactly the same, the packet must be transmitted as-is, header and payload and everything

orignal then it's not the case

zzz there was no RI block )))

orignal yes but you see files in netdb

orignal I still didn't implement split

zzz I don't know what his RI size is when gzipped by i2pd, or what MTU you're assuming, so I can't answer

zzz but you don't do split RI yet ????? !!!!!!!!!

orignal no )))

orignal I only merge from you

orignal was going to implement it but forgot

zzz maybe your merge has a bug and that's why the session confirmed is failing AEAD

orignal no

orignal because otherwise you wouldn't be able to connect

orignal but you are connected even now

zzz RI size isn't constant

orignal do you send two fragments now?

zzz I'm not logging # of fragments right now, don't know

orignal 1459

orignal your RI now

orignal and BpAT is 1557 ))

orignal at least we know what his problem is

zzz will log # of fragments to see if it correlates

orignal strage that you don't see this problem with 2RRY

orignal because it's 1503

orignal as I said no frags in SessionConfirmed

orignal but I do compression

zzz 2RRY is on the list I posted yesterday

zzz for the retx issue

zzz but only seen BpAT and YXEA for the missing RI issue

zzz let me check other router

zzz only BpAT

zzz here's a new one from YXEAX:

zzz 07/11 19:51:05.601 INFO [ handler 1/1] ort.udp.InboundEstablishState2: Got token request from: /[2001:470:1f13:e56:0:0:0:32]:17971

zzz 07/11 19:51:05.659 WARN [ handler 1/1] outer.transport.udp.PeerState2: Bad encrypted packet:

zzz java.security.GeneralSecurityException: Data payload error

zzz Caused by: net.i2p.data.i2np.I2NPMessageException: Corrupt compressed routerInfo size = 954

zzz Caused by: java.io.EOFException: EOF after reading 0 bytes of 64 byte value

zzz it was completely missing the signature in the RI

zzz actually, not sure who that was from, will need to adjust logging

orignal I will implement split

orignal let me investigate compression issue

zzz ok. may or may not be i2pd, didn't get logged

orignal I meant outgoing session from 2RRY

orignal how does it send SessionConfirmed

zzz ok

orignal do you use max compression level?

zzz i think so, yes

orignal I use default

orignal probably 5

orignal will change to 9

zzz i have some test results on that, let me look

zzz 9 is 30% slower, 2.5% smaller than 5

zzz 5 is 15% slower, 1.5% smaller than 3

zzz 3 is my default but I use 9 for RI in session confirmed

orignal I usually use 0 where compression is required

orignal but here I will set to 9

orignal for SessionConfirmed, PeerTest and RelayIntro

zzz ok, re-enabled my code to make my RI huge, and immediately had a failure with i2pd k8vhnd

orignal good point

orignal I wiill check

zzz theyRelayToUsAs: 1864394615

orignal but I hope it doesn't exceed 3K

zzz can't remember but I think I reduced it to be sure it was under that

orignal because I have 3K max now

zzz going to enable it on my other router too so you get a double blast

zzz this is strange because we tested it before. will be interesting to see what broke

zzz already hit 3PYq, bAU~, ImQC also

orignal maybe I have broken something recently

zzz now tXc6

zzz so get ready with your logging, it will get to you soon

orignal but it will tell nothing for now

orignal I see the issue

orignal fragments don't fit buffer

orignal I will fix

orignal in 15 mintes

dr|z3d you should hire orignal, zzz, he charges by the mint :)

orignal what?

dr|z3d lost in translation again *sigh*

orignal no

orignal just busy

dr|z3d oh, well, don't mind me, I was just trying to be amusing. :|

orignal github.com/PurpleI2P/i2pd/blob/openssl/libi2pd/SSU2Session.cpp#L695

orignal dr|z3d look at that code ))

orignal I should be fired from everywhere for this

zzz lol

orignal returned pounter to a local buffer

orignal childish mistake

orignal fixed

zzz shit happens

zzz good job

zzz lets see how it goes

zzz R4SAS, please update your routers

orignal I told everybody already

zzz ok

orignal now time to fix sending

orignal there is no ih in your RI anymore. why?

R4SAS updated bunch of routers

zzz thanks R4SAS

zzz orignal, having trouble making connections because of my big RI :)

orignal even with Java?

orignal -Akx: 81.7.18.46 => [1912:15261]

orignal And I see you connected

orignal incoming conniction

zzz no, no problems with java, but I can't publish ih unless I have SSU2 introducers :)

zzz not guaranteed 100% of the time

orignal but you said you can't connect

orignal yes I understand you can't connect to i2pd due that bug

zzz I have about 5 connections right now, none of them are introducers

orignal how is it possible?

orignal <orignal> -Akx: 81.7.18.46 => [1912:15261]

orignal it's not an introducer because you didn't request relay tag

orignal that makes sense becaus it's ipv4 only

zzz right, I'm only v6 firewalled

zzz will review the logs and see how things look in the morning

orignal but my question is

orignal if you use ipv4 connection as ipv6 introducer or not

orignal -Akx: [2a02:180:2:92:92:92:11:15] => [1739:669] [itag:1472016776]

orignal on 2RRY

orignal why it was disconneted?
