These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date. Bert Wesarg (6): attach the forwarding type to struct Forward merge local and remote forward lists generate unique ids for forwardings to be used for identification remove closed forwardings from

....org LocalForward 12345 localhost:54321 This seems to happen with ssh when scp invokes it to connect to the remote host, for example: % scp mindrot.org:.cshrc /dev/null xfree: NULL pointer given as argument gdb shows this happens on this line in readconf.c: xfree(options->local_forwards[i].listen_host); It's possible (perhaps likely) there are other similar problems in this routine. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
