[apparmor] [Bug 737074] [NEW] apache2 apparmor module missing link against libapparmor

[Steve Beattie]

Public bug reported:

For some reason, the apparmor 2.6 build of mod_apparmor is failing to
link properly against libapparmor:

ubuntu at natty-i386:~$ sudo /etc/init.d/apache2 restart
 * Restarting web server apache2
 ... waiting    ...done.
ubuntu at natty-i386:~$ sudo a2enmod apparmor
Enabling module apparmor.
Run '/etc/init.d/apache2 restart' to activate new configuration!
ubuntu at natty-i386:~$ sudo /etc/init.d/apache2 restart
apache2: Syntax error on line 203 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/apparmor.load: Cannot load /usr/lib/apache2/modules/mod_apparmor.so into server: /usr/lib/apache2/modules/mod_apparmor.so: undefined symbol: aa_change_hat
Action 'configtest' failed.
The Apache error log may have more information.
   ...fail!
ubuntu at natty-i386:~$ ldd /usr/lib/apache2/modules/mod_apparmor.so
        linux-gate.so.1 =>  (0x00779000)
        libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x009fa000)
        /lib/ld-linux.so.2 (0x0018f000)

(this is with the 2.6.0-0ubuntu2 package in natty, I know 2.6.0-0ubuntu3
has been uploaded, but nothing should be different in that version.)

** Affects: apparmor
     Importance: High
         Status: In Progress

** Affects: apparmor/2.6
     Importance: High
         Status: In Progress
