will check msg 3
orignal
I have found the problem, but why you didn't have invalid signature?
zzz
version check is earlier
orignal
fixed
orignal
as for me I prefer to check signature first and then process content

18:59:55@271/info - SSU2: Peer test 4 error code 65
orignal
do you check it when you pick Charlie?
orignal
lol it's me who doesn't check it ))
orignal
will fix
orignal
SSU2: PeerTest msg=7 code=0
orignal
finally. peer test was successive
zzz
checked in a bunch of MTU fixes, I should go all the way to 1500 now
zzz
I think i2pd is exceeding the MTU; I got a 1517 byte packet from ImQC
orignal
thzt's bug
orignal
because const size_t SSU2_MTU = 1488;
orignal
do you know what was in that packet?
zzz
I have several examples, as best as I can tell they each contained only a single first fragment block (I don't log padding anymore)
orignal
that's enough
orignal
I will look into it
orignal
it's not just mtu problem but also buffer overflow
zzz
FYI I'm now assuming full 1500 default MTU when published as "SSU2", as per the spec
zzz
in each case of a big packet, I never got the other fragment
orignal
what do you mean?
orignal
you never get a follow-on packet or what?
zzz
correct
orignal
do you even receive follow-on fragments?
zzz
ever?
orignal
yes
zzz
i certainly do from java... looking for i2pd...
orignal
I guess I know what it is
orignal
resends
zzz
no, I haven't found a single follow-on fragment from i2pd
orignal
thanks. will check
zzz
I have this big cheat sheet of who is java and who is i2pd to make things easier :)
orignal
do you see some error instead?
zzz
nothing obvious, no
orignal
maybe be endianess of msgid?
zzz
doesn't really matter as long as you do it the same both places
zzz
I suggest you do some tests to see if you're sending and handling fragmented messages correctly
orignal
yes, that's what I'm going to do
zzz
great. hard for me to prove anything from this side
orignal
strange that you don't receive it at all
orignal
that confuses me
zzz
that's not 100% sure. If it's completely corrupt including the header it may not get logged
zzz
hint: one easy way to test is to internally force a really low MTU, like 600
zzz
and log an error if you ever send anything bigger than mtu
zzz
or even 400 MTU. you want to test 3+ fragments, not just 2. Follow-on fragments have 5 bytes more overhead. I had a lot of mtu bugs too
zzz
and I may have more, not sure
