Hi Jeetu,
I finally had some time to check out. I definitively can reproduce your
problem.
I believe it's linked to reentrency problems in libssh, in combination
with the callbacks in your code.
I'm trying to find a solution for this.

Aris

Hi Jeetu,
I apologize, still had no time to check it. I'm pretty busy and all my
free time is swallowed by another project. I hope I can free myself an
hour or two next week to debug this.

Hi Aris,
Just wanted to check in if you've had a chance to try out the libssh
server code I've sent and reproduce the errors I've been seeing?
Thanks so much again for looking into this.
Bye for now

Hi Aris,
I'm attaching my proof of concept server code
as.....ebpsshd-singlesession.c has compile instructions at the
beginning of the code. You will also need to generate a key.h file
that holds the public key of the user who will be connecting to this
server - this is tempoarary since as of now I'm not reading this info
from an authorized_keys or something similar.
Just create a key.h file in the same directory and put something like :
#define MY_PUB_KEY "[YOUR PUBLIC KEY WITHIN THESE QUOTES]"
Also as of now ebpsshd-singlesession listens in on port 2000. So ssh
should connect to that port.
I also have a libssh-project-wrapper script that allows me to try this
out without needing to install the libssh i've built. It basically has
the content:
#!/bin/sh
export
LD_LIBRARY_PATH=/home/jeetu/utils/libssh/libssh-project/build/src:/home/jeetu/utils/libssh/libssh-project/build/src/threads
./$1
I have been testing this code with simple examples like xeyes and
xcalc. For some reason xcalc shows the problem much sooner than with
xeyes, maybe because of the volume of data being transmitted to and
fro?
This is proof of concept code with a lot of fiddling with buffer sizes
as I have been trying to study if any of that makes an impact however
please point out any way you think this can be improved on :)
I'm sorry to drop this in your lap especially if it turns out it was
some server side code issue, however I completely appreciate your help
on this. I would like to squash this bug regardless of where it lies
i.e. in my code or libssh, unfortunately my understanding of libssh
and the ssh protocol is a little limited. However I do not want to put
all of this load completely in your lap and if you share your thoughts
and there's something you would like me to look into then please let
me know.
Thanks,
Jeetu

No problem at all :) The code is an independent unit as of now since I
wanted to make it work before I integrate it within my open source
project (eBrainPool)
I'll mail this out to you tomm (not on the machine with the code right now :) )
Thanks so much for looking into this.....truly appreciate it :)

Hi Jeetu,
By seeing your logs, I understand this:
Both side have a hmac error. The openssh client sees it first, sends a
disconnect (that works), then there's the error in the libssh log.
I think I'll need a proof-of-concept code to debug this. Would you mind
sharing your code, or it's not possible (too much integration with
existing code).
If so, do you think I can reproduce the problem by "fixing" samplesshd
to make new X11 channels connection connect to the local X11 unix socket ?
Thanks.

This is not a problem and shouldn't cause invalid MAC errors. I'm on
travel so I'll look at the log when i'm back.
Thanks so much Aris :)

I've attached a log of the libssh server
