 .
   [ Mihai Moldovan ]
   * New upstream release (4.0.5.1):
     - onmainwindow.cpp: include sshd PID file path option in quotes to support
       whitespaces within the var directory path on Windows. Add comment to
       revisit this later on non-Windows-platforms, too. Fixes: #916.
     - onmainwindow.cpp: do NOT reformat. Reverts most of the previous commit
       because it breaks code logic.
     - res/txt/packs: add adaptive method.
     - {macbuild.sh,x2goclient.pro}: pass MacPorts library and include path's
       to qmake. Due to the qt4-mac's changes, we do not automatically get
       these values automatically "appended" in a usable way anymore.
     - x2gosettings.cpp: let centralSettings () return false on Windows.
     - onmainwindow.cpp: be more precise in slotScDaemonError () regarding
       unknown and undefined errors.
     - onmainwindow.{cpp,h}: don't use a hardcoded path to xmodmap on OS X and
       handle errors more gracefully. Fixes: #487.
     - x2goclient.pro: fix typo --stdlib=... -> -stdlib=... Fixes: #973.
     - onmainwindow.cpp: add some more error handling for parsing the return
       value of x2golistsessions. As it turns out, it can happen that "invalid"
       strings are inserted in there, for instance by the perl interpreter
       itself. We need to skip over these, or the client crashes when splitting
       up the invalid lines.
     - macbuild.sh: add stdlib forcing. Should not be used unless you really
       know what you're doing. If you ponder using this, you probably don't.
     - res/resources.rcc: add Turkish translation file. Fixes: #987.
     - onmainwindow.cpp: use lowercase version of locale. Fixes: #953.
       Fixes loading up the nb_NO translation file, which is actually baked as
       nb_no into the binary.
     - sshmasterconnection.cpp: let challenge-auth-based login attempts
       fallback to normal password authentication if the initial
       challenge-auth-based attempt was unsuccessful.
     - sshmasterconnection.{cpp,h}: support variable number of
       challenge-auth-code-based prompts.
     - sshmasterconnection.cpp: don't check prompts for full string equality -
       a matching prefix is good enough. Amongst others, this fixes errors in
       conditions where the prompt does not contain a trailing whitespace, but
       X2Go Client expects one.
     - sshmasterconnection.cpp: add OATH TOTP prompt prefix. Fixes: #860.
     - res/i18n: refresh translation files again.
     - res/i18n/x2goclient_nb_no.ts: replace "X-Serv..." with "X.Org Server"
       where applicable.
     - res/i18n/x2goclient_nb_no.ts: correctly use "XQuartz" where necessary.
     - res/i18n/x2goclient_nb_no.ts: whitespace only.
     - res/i18n/x2goclient_nb_no.ts: fix up some "x2go" -> "X2Go" errors.
     - res/i18n/x2goclient_nb_no.ts: mark translation strings needing some care
       ("x2go..." -> "X2Go...") as unfinished for later fixup.
     - res/i18n/x2goclient_nb_no.ts: fix (meta data) typo introduced with last
       commit.
     - res/i18n/x2goclient_nl.ts: fixup translation by respecting the original
       messages' format and other changes.
     - res/i18n/x2goclient_de.ts: fixup translation by respecting the original
       messages' format, fixing typos and general improvements.
     - res/i18n/x2goclient_es.ts: fixup translation by respecting the original
       messages' format and other changes.
     - res/i18n/x2goclient_sv.ts: fixup translation by respecting the original
       messages' format and other changes.
   * debian/control:
     - Change apache2-dev | libc6-dev build dependency back to apache2-dev
       only. Otherwise, apache2-dev is not installed at all, even though
       theoretically available. The initial reasoning for this dependency type,
       apache2-dev not being available on all Ubuntu/Debian platforms, is not
       true anymore.
     - Change apache2-dev build dependency yet again to apache2-dev |
       apache2-threaded-dev. Turns out all Debian distros but wheezy (currently
       oldstable) have an apache2-dev package. Even oldoldstable (squeeze)
       does...

   * New upstream release (4.0.5.1):
     - xinerama.conf: Don't choke if screen coordintate lines in xinerama.conf
       start with a dash ("-"). (Fixes: #948).

   [ Mike DePaulo ]
   * New upstream release (4.0.5.1):
     - Windows: Update bundled Win32 OpenSSL from 1.0.1p to 1.0.1q,
       which fixes the multiple CVEs announced on 2015-12-03.
     - Windows: Upgrade Cygwin components to latest versions as of
       2016-01-21, except for the Cygwin DLL which is still at 1.7.33
       in order to avoid breaking folder sharing and printer sharing
       due to 1.7.34's ACL/permissions changes.
       (authorized_keys file would often have mode 660 instead of 600)
       The latest components include most notably:
         + openssh 6.8p1-1-x2go1 -> 7.1p2-1-x2go1 (security update)
         + openssl 1.0.2d-1 -> 1.0.2e-1 (security update)
     - Windows: Update nxproxy from 3.5.0.31 to 3.5.0.32
     - Windows: Update Unicode NSIS from 2.46.5 to 2.50.0 Pre-release,
       which fixes the DLL hijacking security vuln (NSIS bug 1125.)
     - Windows: Update PuTTY from 0.64 to 0.66, which fixes
       CVE-2015-5309.
     - Windows: Remove libzip. libssh no longer uses it.

   * New upstream release (4.0.5.1):
     - ssh{process,masterconnection}.cpp: run bash as a login shell when
       invoking any command remotely. Fixes: #928. Because this opens the door
       for ~/.bash_logout and friend scripts to be executed, which may contain
       calls to ncurses' reset or clear, also set the TERM variable to dump to
       not have unexpected output on stderr at logout time.
     - sshmasterconnection.cpp: check correct variable for validity: public key
       instead of private key (again.) Fixes: #945.

   [ Klaus Ade Johnstad ]
   * New upstream version (4.0.5.1):
     - res/i18n/x2goclient_nb_no.ts: update Bokmål (Norway) translation file.
 .
   [ Heinrich Schuchardt ]
   * New upstream version (4.0.5.1):
     - sshmasterconnection.cpp: don't fetch invalid proxy socket. Fixes: #1000.
       From http://doc.qt.io/qt-4.8/qabstractsocket.html#socketDescriptor:
       The socket descriptor is not available when QAbstractSocket is in
       UnconnectedState.
       So we have to connect to the proxy server first before retrieving the
       native socket.

Subject: x2goclient 4.0.5.0 overwrites user's shell

Date: Tue, 25 Aug 2015 11:28:02 -0600

[Message part 4 (text/plain, inline)]

Package: x2goclient
Version: 4.0.5.0
Tags: patch

See https://bugzilla.redhat.com/show_bug.cgi?id=1256799

Description of problem:
After upgrading x2goclient my system assigned shell of /bin/zsh is ignored and
forcefully set to /bin/bash

The shift to running everything under /bin/bash had the side effect of setting
SHELL to /bin/bash, which is then what terminal emulators and others use for
spawning shells.

If we specify -l to bash it runs as a login shell, sources the proper startup
files and sets SHELL to whatever getpwent() returns for the login shell.

However, this also opens the door for things like ~/.bash_logout to get run
which executes "clear", which emits:

TERM environment variable not set.

when TERM is empty as it is here.  So we also set TERM=dumb to work around that.


It might be nice to add the ability to distinguish between a session startup
command and other utility commands (x2gomountdirs, etc.) and only add -l to
the session startup commands.  This is probably more appropriate.
