...l implicitely allocate a struct ssh and return it after then set the fds in it. sshd.c appears to be the only place where the API is still used, so we can place that sequence there. sshd.c calls the old function only once during initialization (in main()) so it does appear to arrive there while active_state is still NULL. So when called with active_state==NULL, essentially the old function is roughly equivalent to: struct *ssh = ssh_alloc_session_state(); ssh_packet_set_connection(ssh, fd_in, fd_out) active_state = ssh; ssh.c handles this in a similar way. It calls ssh_alloc_se...

...of OpenSSH. Here is a brief description of the problem: I have a raw memory dump, and all of the kernel data structures (e.g., task_struct, mm_struct) have been figured out. Now, I want to retrieve the data structures (e.g., struct session_state) of an SSH process instance. Finding a session key (active_state->newkeys) could be an example. In order to find these information, I think I need a starting point (i.e., memory address) of the OpenSSH data structures. Does anyone know how to tackle this problem? Any comments and suggestions are much appreciated. Thanks, Fengwei

...easily be rearranged so that is clearer who owns which memory and who is thus responsible for freeing. Also, the the ssh_login function leaks the memory allocated to the host variable. Also, there is another global variable (previous_host_key) which could be removed by placing it into the ssh/active_state structure, but which, for now, could at least be made module-static. Proposal: ssh-connect allocates the initial memory and creates values and passes these as parameters to the relevant functions. It passes them also to ssh_kex2 which makes a true copy. ssh-connect frees its memory and t...

We are attempting to use openssh sftp to connect to a server that is running some version of the Axway SFTP server. After a publickey auth completes, the server resends publickey as a valid auth. This results in a loop as openssh sftp resubmits the publickey information. This seems similar to a discussion in 2014 that terminated with the thought that it might be nice if the client tracked

Hi, OpenSSH 6.8 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This release contains some substantial new features and a number of bugfixes. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is
