tests: modify proxyjump tests to check for ssh_jump_info_struct tests: add proxyjump functionality test feat: add SSH_OPTIONS_PROXYJUMP tests: proxyjump, check authentication fix: ssh_socket_connect_proxyjump add exit label to exit on error feat: implement io forwarding using pthread feat: proxyjump: use threading instead of forking feat: proxyjump: cancel forwarding threads on ssh_disconnect fix: proxyjump remove ProxyJump bool and put pthread ifdefs feat: use ssh_event for io forwarding instead of threads reformat: tests to use assert_int_not_equal fix: link to pthread refactor: make function to free proxy jump list docs: add comment for proxy jump channel feat: add env variable to enable libssh proxy jump feat: open channel for proxyjump like OpenSSH feat: add more tests for proxy jump fix: use a global variable to close io forwarding, this prevents segfaults fix: handle proxy list in thread without creating copy Signed-off-by: Gauravsingh Sisodia <xaerru@gmail.com> Reviewed-by: Jakub Jelen <jjelen@redhat.com> Reviewed-by: Eshan Kelkar <eshankelkar@galorithm.com>
