| 08:20 | Handle socket errors on half-open channels. Anthony Ho reports that this can occur naturally in some situation involving Windows 8 + IE 11 and dynamic port forwarding: apparently we get through the SOCKS negotiation, send our CHANNEL_OPEN, and then *immediately* suffer a local WSAECONNABORTED error before the server has sent back its OPEN_CONFIRMATION or OPEN_FAILURE. In this situation ssh2_channel_check_close was failing to notice that the channel didn't yet have a valid server id, and sending out a CHANNEL_CLOSE anyway containing 32 bits of uninitialised nonsense. We now handle this by turning our half-open CHAN_SOCKDATA_DORMANT into a half-open CHAN_ZOMBIE, which means in turn that our handler functions for OPEN_CONFIRMATION and OPEN_FAILURE have to recognise and handle that case, the former by immediately initiating channel closure once we _do_ have the channel's server id to do it with. check-in: 1593971ebd user: simon tags: trunk | |
| 02:14 | Pass an error message through to sshfwd_unclean_close. We have access to one at every call site, so there's really no reason not to send it through to ssh.c to be logged. check-in: 36349ac57c user: simon tags: trunk | |

| 11:15 | Fix SSH2_MSG_CHANNEL_EXTENDED_DATA in logparse. It looks as if it's never worked at all: it had a spurious second printf, it completely forgot to allow for the uint32 type code that SSH2_MSG_CHANNEL_DATA doesn't have, it accessed the channel state's sequence number fields in a way that made no sense and didn't match the rest of the program, *and* it misinvoked the file opening API. I must have never had an occasion to test it. check-in: a938a3ac2e user: simon tags: trunk | |
| 11:15 | Make logparse handle completely bogus channel numbers. Previously it would throw a bunch of Perl undefined-variable-usage warnings; now it cleanly detects the problem, dumps as much of the message as it still reasonably can, and doesn't update any channel states. check-in: 21376cee1b user: simon tags: trunk | |

| 06:55 | Fix free of an uninitialised pointer. CHAN_AGENT channels need c->u.a.message to be either NULL or valid dynamically allocated memory, because it'll be freed by ssh_channel_destroy. This bug triggers if an agent forwarding channel is opened and closed without having sent any queries. check-in: 7b9042322c user: simon tags: trunk | |

| 12:45 | Fix handling of IPv6 dynamic forwardings. During the Conf revamp, I changed the internal representation of dynamic forwardings so that they were stored as the conceptually sensible L12345=D rather than the old D12345, and added compensation code to translate to the latter form for backwards-compatible data storage and for OpenSSH-harmonised GUI display. Unfortunately I forgot that keys in the forwarding data can also prefix the L/R with a character indicating IPv4/IPv6, and my translations didn't take account of that possibility. Fix them. check-in: 2ca638ec2c user: simon tags: trunk | |

| 05:56 | Don't run toplevel callbacks in modal dialogs. Because some of them can call gtk_main_quit(), which completely confuses the dialog box system. check-in: d89571a733 user: simon tags: trunk | |
