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

orignal I don't have MTU implemented it

orignal it's always 1488 for now

zzz sure but whatever it is, don't go over :)

orignal looks like two different problems

orignal btw what is 1517?

orignal including UDP and IP headers or just payload?

zzz 1517 was including udp and ip headers and SSU2 header and SSU2 MAC

orignal that explains

orignal that part will be fixed

orignal and hence no buffer overflow

orignal just extra headers

orignal 1488 + 28 = 1516

orignal that where it comes from

zzz 48 for ipv6, don't forget :)

orignal yes I know

orignal I counted it

orignal got SSU2: PeerTest msg=4 code=65 again

orignal any idea why it happens?

orignal e.g. how do you pick session with Charlie?

orignal and SSU2: PeerTest msg=4 code=70 from another

orignal and SSU2: PeerTest msg=4 code=68

orignal but this one seems reasonable

orignal SSU2: RelayResponse status code=70

orignal interesting code 70 for PeerTest and for RelayIntro

zzz Peer Test responses as charlie last 6 days

zzz 0 60%

zzz 65 24%

zzz 67 2%

zzz 68 12%

zzz 70 1%

zzz Relay responses as charlie last 6 days

zzz 0 0%

zzz 65 50%

zzz 67 38%

zzz 68 3%

zzz 70 9%

orignal my question is where 65 comes from

orignal basically why it happens

orignal especially for relay

orignal since Alice know where is she trying to connect to

zzz looking...

orignal for 67 I need to double check

zzz for relay, the 65's are all 6to4 addresses 2002::

zzz for peer test, the 65's are either 6to4, or port 0

orignal for Alice?

zzz yes

orignal but why I receive 65?

orignal I'm 2001:470

zzz the peer test or relay address for alice is invalid

orignal peer test

orignal it looks like Bob chooses ipv4 session with Chralie

orignal and Chrlie doesn't support ipv6

zzz we will never connect to or test or relay to a 6to4 address 2002::

orignal I don't care

orignal but you said Alice has such wrong address

orignal and I receive 65 on Alice with 2001:470

zzz the bob/charlie connection is usually ipv6

orignal do you check charlie when pick Bob-Charlie session?

zzz right, you are bob, you asked me charlie to do a peer test with alice [2002:b28d:383b:0:0:0:b28d:383b]:9733

orignal for compatibility

orignal that's another problem

orignal I'm asking about my own Alice

zzz I think so. It's compatible, it's just not a valid address

orignal but again my address is defintly valied

orignal and I receive 65 frequetly

zzz ok let me look for you as alice

orignal I don't know who was Charlie

orignal and it doesn't happen with relay response

orignal but this strange 70

zzz 2RRY is not at 2001:470

orignal not 2RRY

zzz 70 is mostly fixed, only happened once in last week

orignal one with ipv6 only

orignal what was the issue with 70?

orignal and why I receive it for both peer test and relay

orignal my impression that you don't recognize first RouterInfo block

zzz I think I mentioned, I wasn't handling out-of order, now I delay and recheck if I don't have RI yet

orignal it only happens when Bob is i2pd

orignal yes but it's not the case

zzz so probably just java routers that don't have the fix yet

orignal i2pd sends RI, relay intro blocks in one message

orignal and I got 70 if Bob is i2pd

zzz put the relay intro block before the RI block, it will probably help

orignal no, that 70 was through 2RRY

orignal and relay was sent to you

orignal my concern is that it happens with both peer test and relay

zzz I know what router that is, my routers really really don't like it. I think it's banning it or something else is wrong

zzz I can't load the RI on any router

orignal I don't understand

orignal that RI was mine

zzz I don't understand either, but there's something wrong with that ipv6-only router of yours

zzz 4 days ago the relay signature was failing, and I've never been able to lookup the RI from a ff

orignal that's right

orignal I run it rarely and it's not in netdb

zzz ok

orignal but it doesn't explain why 70

orignal you should receive it in RI block

orignal you think RI block is invalid?

zzz I don't know. leave it running and we can try to figure it out

orignal fine. will do for couple hours

orignal 07:58:05@187/info - SSU2: RelayResponse status code=70

orignal can you take a look?

orignal it's just now

orignal 70 is from you

orignal and at the same time

orignal 07:58:03@187/debug - SSU2: PeerTest msg=7 code=0

orignal another attempt

orignal 08:07:44@187/info - SSU2: RelayResponse status code=67

orignal 67 looks better

zzz yes, 70 first time, 67 the next time

zzz also had a 67 4 days ago

zzz The RI looks fine

zzz but the signature of the relay data is bad

orignal then why 70?

zzz looking...

orignal I'm checking signature

orignal looks like you recognized RI from first message ib second message

zzz ok. this is a i2pd bob PeGQ

zzz the first time there was no RI block, only a 172 byte packet:

zzz 06-26 13:58:03.358 DEBUG [ handler 1/1] outer.transport.udp.PeerState2: New 172 byte pkt 92 rcvd on [2a05:4800:3:161:0:0:10:c]:11916 PeGQYG

zzz the second time there was a RI block, 1136 byte packet:

zzz 06-26 14:07:44.426 DEBUG [ handler 1/1] outer.transport.udp.PeerState2: New 1136 byte pkt 96 rcvd on [2a05:4800:3:161:0:0:10:c]:11916 PeGQYG

zzz the first time I returned a 70, next time a 67

orignal maybe they run older code

orignal found another bug

orignal when I pick Charlie I don't exlude session with Alice

orignal will fix it

orignal for peer test

zzz don't know why bob would not send RI first time, would send RI second time

zzz and of course other problem is the signature

orignal because it was different Bov, no?

orignal or it's the same?

orignal if it's the same I guess I know why

orignal race condition

zzz I've had 14 relay signature failures in last week. 10 are from that ipv6 router.

zzz not sure how many bobs

zzz looking...

orignal both cases are clear now

orignal will fix

zzz about 4 different bobs, all i2pd

orignal found the issue with signature

orignal ver is missing

zzz great

orignal 10:17:07@644/info - SSU2: RelayResponse status code=68

orignal 68 now

zzz yes I see it

orignal I did something wrong

orignal because I couldn't parse some messages from you

orignal but at least I tried to connect

orignal lol. I have an incoming connection from your to that router

orignal hence can't test relays
