openssh bugs - Mar 2010 - [Bug 1729] New: Bash environmental associative arrays not getting set

https://bugzilla.mindrot.org/show_bug.cgi?id=1729

           Summary: Bash environmental associative arrays not getting set
           Product: Portable OpenSSH
           Version: 5.2p1
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2
         Component: ssh
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: woodsdog at gmail.com


In Bash 4.0 associative arrays were introduced.  There are some
environmental variables that are associative arrays.  One of these
variables is the BASH_ALIASES associative array.  Documentation can be
found here:

http://www.gnu.org/software/bash/manual/bashref.html#Bash-Variables

In short, it's an active array of the system aliases,  with both the
alias and the corresponding command kept track of.

For example, to set:

$ BASH_ALIASES[cdt]="cd /tmp"

would be the equivalent of:

$ alias cdt="cd /tmp"

Setting this variable, the alias is instantly available in that bash
environment.

Now, when passing these variables with SSH, ssh doesn't interpret these
variables as special.  I've tested this on two different distros,
Fedora 12 (OpenSSH_5.2p1) and Ubuntu 9.10 (OpenSSH_5.1p1).  Both give
different the same bad result.

My environment file:

$ cat environment 
BASH_ALIASES[cdt]="cd /tmp"
TESTME="This is a test"

On F12 & Ub 9.10:
-after an ssh to Ub 9.10 box, the $TESTME variable is set and can be
seen when the 'set' or 'env' command is run. The $BASH_ALIASES
variable
appears in the list as a regular environment variable, ignoring the
associative  There is no "cdt" alias either.  It didn't add this
to the
associative array.

$ env | grep BASH
BASH_ALIASES[cdt]="cd /tmp"
$

I don't think that this is under our control - OpenSSH passes all
variables though execve() and doesn't filter them if they contain
special characters (e.g. square brackets). Perhaps your kernel or bash
itself it rejecting them?
