2007-06-12* New upstream release (closes: #395507, #397961, #420035). ImportantColin Watson
changes not previously backported to 4.3p2: - 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4): + On portable OpenSSH, fix a GSSAPI authentication abort that could be used to determine the validity of usernames on some platforms. + Implemented conditional configuration in sshd_config(5) using the "Match" directive. This allows some configuration options to be selectively overridden if specific criteria (based on user, group, hostname and/or address) are met. So far a useful subset of post-authentication options are supported and more are expected to be added in future releases. + Add support for Diffie-Hellman group exchange key agreement with a final hash of SHA256. + Added a "ForceCommand" directive to sshd_config(5). Similar to the command="..." option accepted in ~/.ssh/authorized_keys, this forces the execution of the specified command regardless of what the user requested. This is very useful in conjunction with the new "Match" option. + Add a "PermitOpen" directive to sshd_config(5). This mirrors the permitopen="..." authorized_keys option, allowing fine-grained control over the port-forwardings that a user is allowed to establish. + Add optional logging of transactions to sftp-server(8). + ssh(1) will now record port numbers for hosts stored in ~/.ssh/known_hosts when a non-standard port has been requested (closes: #50612). + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a non-zero exit code) when requested port forwardings could not be established. + Extend sshd_config(5) "SubSystem" declarations to allow the specification of command-line arguments. + Replacement of all integer overflow susceptible invocations of malloc(3) and realloc(3) with overflow-checking equivalents. + Many manpage fixes and improvements. + Add optional support for OpenSSL hardware accelerators (engines), enabled using the --with-ssl-engine configure option. + Tokens in configuration files may be double-quoted in order to contain spaces (closes: #319639). + Move a debug() call out of a SIGCHLD handler, fixing a hang when the session exits very quickly (closes: #307890). + Fix some incorrect buffer allocation calculations (closes: #410599). + ssh-add doesn't ask for a passphrase if key file permissions are too liberal (closes: #103677). + Likewise, ssh doesn't ask either (closes: #99675). - 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6): + sshd now allows the enabling and disabling of authentication methods on a per user, group, host and network basis via the Match directive in sshd_config. + Fixed an inconsistent check for a terminal when displaying scp progress meter (closes: #257524). + Fix "hang on exit" when background processes are running at the time of exit on a ttyful/login session (closes: #88337). * Update to current GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch; install ChangeLog.gssapi.

if Krb5 library exports krb5_init_etc() since some OSes (like MacOS/X) are starting to restrict it as internal since it is not needed by developers any more. (Patch based on Apple tree) - (bal) [monitor.c monitor_wrap.c] monitor_wrap.c] moved zlib.h higher since krb5 on MacOS/X conflicts. There may be a better solution, but this will work for now.
