Hi guys Apparently, there is small memory leak in the do_ssh2_kex() routine in sshd.c. Line 2195 in sshd.c states: myproposal[PROPOSAL_SERVER_HOST_KEY_ALGS] = list_hostkey_types(); Where list_hostkey_types() returns a pointer allocated by the xstrdup call (line 735). This pointer should be freed in the calling routine do_ssh2_key(). Should I make a patch for this? Also, since my previous patch was not according to the your standards, how many lines of context do you no...

Dear all, For my thesis, I've been working on automatic inference of state machines for SSH servers. I ran into a couple of particularities regarding OpenSSH's inferred state machine, and was hoping some of you might be interested. Maybe you can even shed some light on it. Setup: I'm using LearnLib's (Java) version of the L* learning algorithm [1] to come up with sequences of
