| 18:00 | Should have been part of r9663: do use the platform-independent version of smemclr when compiling with Winelib. check-in: 55418d7f9a user: ben tags: trunk | |
| 17:34 | Tweak comment in Recipe that had become separated from its code. check-in: 1728fb86ce user: ben tags: trunk | |
| 17:34 | Don't try to use SecureZeroMemory under Winelib, since it isn't available there (yet). check-in: 9576fab1e6 user: ben tags: trunk | |
| 17:33 | Define SECURITY_WIN32 for Winelib/Cygwin builds as well as for VC. This should perhaps go into winmisc.c: it's caused problems for other people too: <http://stackoverflow.com/questions/8530159/vs2010-build-error-at-putty-source> check-in: a1328977bc user: ben tags: trunk | |
| 16:53 | In the cygwin Makefile, use "-o" on the windres command line to specify the output file. This appears to be supported by windres, and is required by wrc (the Winelib resource compiler). check-in: 8ed9ff86c4 user: ben tags: trunk | |

| 14:46 | Most of the code for "nc" mode duplicated that for opening a session or a fowarded port. Arrange that this code is shared instead. The main visible change is a slight change of log messages. check-in: 45e5597a72 user: ben tags: trunk | |
| 05:40 | Hiroshi Oota points out that PuTTY's agent forwarding sockets can get confused if they receive a request followed by immediate EOF, since we currently send outgoing EOF as soon as we see the incoming one - and then, when the response comes back from the real SSH agent, we send it along anyway as channel data in spite of having sent EOF. To fix this, I introduce a new field for each agent channel which counts the number of calls to ssh_agentf_callback that are currently expected, and we don't send EOF on an agent channel until we've both received EOF and that value drops to zero. check-in: 18cc9933bb user: simon tags: trunk | |

| 07:28 | Factor out some common code for constructing SSH2_CHANNEL_OPEN. check-in: a820fa2f7d user: ben tags: trunk | |
| 07:10 | struct winadj is unused now. G/c it. check-in: 215a9bd3fa user: ben tags: trunk | |
| 07:03 | All of the initial CHANNEL_REQUESTs are conditional on (ssh->mainchan && !ssh->ncmode), so bundle them up in a big block conditional on this rather than checking it five times. check-in: 7cd9f82d83 user: ben tags: trunk | |
| 06:32 | do_ssh2_authconn() now installs the standard handlers for CHANNEL_SUCCESS and CHANNEL_FAILURE as soon as it's opened a channel, so there's no need for it to set them again later. check-in: 3f43707fed user: ben tags: trunk | |

| 13:48 | Memory leak fixes reported by Balazs Domjan. check-in: 837bb0029b user: simon tags: trunk | |
| 13:44 | Rename the various ssh2_maybe_setup_* functions to ssh2_setup_*, and move the primary conditions out of them into their callers. Fixes a crash in 'plink -N', since those functions would be called with a NULL channel parameter and immediately dereference it to try to get c->ssh. check-in: 91489422bb user: simon tags: trunk | |
| 13:44 | In openssh_read(), we shouldn't ever return SSH2_WRONG_PASSPHRASE for an unencrypted key. (The other import function, sshcom_read(), already got this right.) Thanks to David Wedderwille for the report. This is more than just an error-reporting mistake; it actually causes Windows PuTTYgen to tight-loop on attempting to load a corrupt OpenSSH key, because the 'wrong passphrase' return value causes the caller to loop round and try again, but of course it knows the key is unencrypted so it doesn't prompt for a different passphrase and just tries again with no change... check-in: eb33193237 user: simon tags: trunk | |

| 12:42 | Fix a controlling-terminal bug reported by Anthony Heading: Cygwin doesn't have TIOCSCTTY, so my attempt to set the ctty of the child process isn't doing anything, and only works by chance when you run bash because bash does the thing that _will_ set the ctty, namely opening the terminal file again without O_NOCTTY. So now we do that too. check-in: 2728617d96 user: simon tags: trunk | |
| 12:41 | Partially revert r9636. It is true that we can directly return the result of memcmp, but untrue that we can do so _unconditionally_: if memcmp returns zero, we still need to fall through to the next comparison. check-in: 3bce939695 user: simon tags: trunk | |

| 18:16 | Clang, like LCC, objects to using '<' and '>' on function pointers. I'm not entirely sure that using memcmp() is any more defined by the C standard, but at least Clang doesn't complain about it. While I'm here, tree234 doesn't require that comparison functions return precisely +1 or -1, so we can use the return value of memcmp() directly. check-in: 59a02c549d user: ben tags: trunk | |
| 17:02 | Change return type of do_ssh2_transport() to void. Nothing pays attention to it any more, anyway. check-in: 602c100aba user: ben tags: trunk | |
| 16:55 | Make bombout() less of a macro and more of a function. This gives GCC slightly fewer opportunities to gratuitously inflate its output. check-in: e1f8ba8e7b user: ben tags: trunk | |
| 14:11 | Fix a memory leak in parse_ttymodes() (found by Memcheck/Valgrind). check-in: f3232e6fc3 user: ben tags: trunk | |
| 13:44 | Slightly simplify crFinishFree{,V}. They're only likely to be useful for freeing a coroutine state structure, in which case there's no need to reset the line number (since all such coroutines keep their line number in the state structure) and the state structure pointer is always called "s". check-in: fd2ca901e3 user: ben tags: trunk | |
| 12:37 | Don't close SSH-2 channels with outstanding channel requests on local error. In sshfwd_unclean_close(), get ssh2_check_close() to handle sending SSH_MSG_CHANNEL_CLOSE. That way, it can hold off doing so until any outstanding channel requests are processed. Also add event log message for unclean channel closures. check-in: 8f16c188ed user: ben tags: trunk | |
| 09:34 | It's not legal to free a coroutine's state structure before invoking crFinish or crFinishV, since they will attempt to write to the coroutine state variable contained in that structure. Introduced some new all-in-one macros crFinishFree and crFinishFreeV, and used those instead. Should fix today's report of a crash just after authentication. check-in: edfebde5a7 user: simon tags: trunk | |

| 04:19 | Remove documentation for "Out of space for port forwardings" error. It no longer exists in the code, and should have been obsoleted by r9214 at the latest. check-in: 188ae2adc3 user: ben tags: trunk | |

| 17:57 | Improve window-size handling in Unix Plink. Unconditionally override the configured terminal size with the one from stdin if it's available. This avoids the silliness whereby if Default Settings had a terminal size set, Plink used this and thus caused the server to use the wrong size. check-in: 102e90f6af user: ben tags: trunk | |
| 16:06 | Better handling of outstanding CHANNEL_REQUESTS on channel destruction. Part the first: make sure that all structures describing channel requests are freed when the SSH connection is freed. This involves adding a means to ask a response handler to free any memory it holds. Part the second: in ssh_channel_try_eof(), call ssh2_channel_check_close() rather than emitting an SSH_MSG_CHANNEL_EOF directly. This avoids the possibility of closing the channel while a CHANNEL_REQUEST is outstanding. Also add some assertions that helped with tracking down the latter problem. check-in: c87aa624ea user: ben tags: trunk | |
| 10:57 | Factor out common code to construct CHANNEL_REQUESTS. This reduces code size a little and also makes it harder to accidentally request a reply without putting in place a handler for it or vice versa. check-in: 3182a9a27e user: ben tags: trunk | |
| 10:04 | Simplify handling of responses to channel requests. The various setup routines can only receive CHANNEL_SUCCESS or CHANNEL_FAILURE, so there's no need for the to worry about receiving anything else. Strange packets will end up in do_ssh2_authconn instead. check-in: 054111be55 user: ben tags: trunk | |
| 09:34 | Add some kind of window tracking to logparse.pl. check-in: c22f69b213 user: ben tags: trunk | |
| 08:54 | Fix matching of channel and global requests with replies in logparse.pl. In each case, want_reply was being treated as true even when it wasn't, because it got decoded into "yes"/"no", both of which are true in Perl. check-in: 85c62a0921 user: ben tags: trunk | |
| 08:39 | Handle all replies to CHANNEL_REQUESTs through the per-channel queue. Each of the minor start-of-session requests is now dealt with by its own little co-routine, while the shell/command is done in do_ssh2_authconn() itself. This eliminates one more round-trip in session setup: PuTTY gets all the way up to sending a shell request before worrying about any replies. check-in: f8eedbd544 user: ben tags: trunk | |
| 06:12 | Generalise SSH_MSG_CHANNEL_{SUCCESS,FAILURE} handling. Now each channel has a queue of arbitrary handlers for those messages, with anything that sends a CHANNEL_REQUEST with want_reply true pushing a new entry onto the queue, and a shared handler that dispatches responses appropriately. Currently, this is only used for winadj@putty.projects.tartarus.org, but extending it to cover the initial requests as well shouldn't be too painful. check-in: 008c38a33f user: ben tags: trunk | |

| 13:36 | Fix a bug in the PSFTP command parser which would cause it to hallucinate an extra empty argument word at the end of a line if the line ended in more than one whitespace character. check-in: 07769e1daf user: simon tags: trunk | |
| 13:25 | Enhance logparse.pl so that it detects channels running SFTP and decodes the SFTP message layer in addition to the underlying SSH. Requests and responses are matched up via their ids. check-in: 297ea2b807 user: simon tags: trunk | |

| 18:04 | Fix recently-introduced memory leak in ssh2_msg_unexpected(). check-in: 4d3163506d user: ben tags: trunk | |
| 17:33 | De-duplicate code in KEXINIT generation. There's no need to have identical code generating server-to-client and client-to-server versions of the cipher and MAC lists; a couple of twice-around loops will do fine. check-in: 8a9f4acc01 user: ben tags: trunk | |
| 17:04 | Reworking of packet delivery to coroutines in SSH-2. Before, NULL in the dispatch table meant "send to the appropriate one of do_ssh2_transport() and do_ssh2_authconn()". Now those (via small shims) are specified directly in the dispatch table, so ssh2_protocol() is much simpler. In the process, this has somewhat centralised the handling of gross server protocol violations. PuTTY will now disconnect with a rude message when (e.g.) OpenSSH sends us an SSH_MSG_UNIMPLEMENTED when we try to KEXINIT during authentication. check-in: 147d6fa6a9 user: ben tags: trunk | |

| 06:35 | Fix an erroneous "case" fallthrough in ssh1_msg_channel_close, which was causing assertion failures when closing X11 channels in SSH-1. Also fix another pasto. check-in: 4c44cc259a user: ben tags: trunk | |
|

| 04:30 | Tweak to SSH coroutine code: put line number in the coroutine state structure, which is consistent with Simon's canonical version of the macros. check-in: e5667a8d0d user: ben tags: trunk | |

| 15:17 | Use a single sftp_senddata() to send each SFTP packet, rather than using one for the length field and one for the rest of the packet contents. Since sftp_senddata() has no queuing or deferral mechanism but instead constructs and sends an SSH2_MSG_CHANNEL_DATA message immediately, this change has the effect of ceasing to split every SFTP packet across two SSH messages. check-in: 46ddd55b12 user: simon tags: trunk | |
|
2012-08-11
| ||
| 04:10 | Rework bufchain code to allow for variable-sized granules. bufchain_add() now allocates at most one new granule. Granules still have a minimum size, so small adds still get coalesced. The main practical consequence of this is that PSCP and PSFTP now generate 4K SSH packets rather than 512-byte ones. Also, the compiled code (on my Ubuntu box) is fractionally smaller. check-in: ead74b235b user: ben tags: trunk | |
|
2012-08-02
| ||
| 17:18 | Reduce the number of round-trips involved in opening an SSH-2 session by sending most of the initial SSH_MSG_CHANNEL_REQUEST messages before waiting for any replies. The initial version of this code was a clever thing with a two-pass loop, but that got hairy so I went for the simpler approach of separating the request and reply code and having flags to keep track of which requests have been sent. check-in: 5da2ce49e0 user: ben tags: trunk | |

| 14:30 | Add a bug-compatibility flag to disable the winadj@putty.projects.tartarus.org request. Not currently enabled automatically, but should be usable as a manual workaround. check-in: feb44c7dcc user: simon tags: trunk | |
| 11:53 | Fix an embarrassing mistake in config box handling which was causing changes to any SSH bug config option to be lost when the config box switched to a different panel, at least on GTK. check-in: 723e01c194 user: simon tags: trunk | |
| 11:33 | Move the declaration of smemclr() out of putty.h into misc.h, because one of its uses (in sshaes.c) wasn't picking up the former. Thanks to Ubuntu's gcc for spotting that. check-in: b41c0f9a37 user: simon tags: trunk | |
| 11:33 | Remove an unused variable. check-in: 5fca0480b8 user: simon tags: trunk | |
|
2012-07-22
| ||
| 14:51 | Introduce a new utility function smemclr(), which memsets things to zero but does it in such a way that over-clever compilers hopefully won't helpfully optimise the call away if you do it just before freeing something or letting it go out of scope. Use this for (hopefully) every memset whose job is to destroy sensitive data that might otherwise be left lying around in the process's memory. check-in: aee68b8d31 user: simon tags: trunk | |
