description |
Problem was discovered in both upstream kernel and in Ubuntu Natty beta kernels. The problem is a regression from Ubuntu Maverick and earlier releases.
When creating a profile for openssh-server, sshd, using the standard AppArmor profile development tools, a _partial_ profile is created and loaded correctly. When trying to iterate the development of the profile, I found that I was unable to log in to the machine via sshd, even though the AppArmor profile had flags=(complain,) at the beginning.
Removing the profile using apparmor_parser --remove /etc/apparmor.d/usr.sbin.sshd allowed the logins to succeed. Reloading the profile and restarting sshd recreates the problem.
The logfiles don't show any REJECT messages; a handful of ALLOWED messages are printed early on, but then _no_ log entries are generated.
The client quits with "broken pipe" errors. |
SRU Justification:
Impact: Can result in confined application failure with no information logged on how to fix the problem.
Fix: Do not mask the capabilities returned by capget when in complain mode, this allows the application
to progress as expected and request the capabilities it will need.
Patch from upstream AppArmor, backported for Lucid and Maverick.
Testcase: Run the attached C test program as root. When run unconfined it will output a hex number corresponding to the effective caps of root. Confine the application with a profile in complain mode using aa-genprof /path/to/test/program. On a none patched kernel it will return 0 as its capability set, on a patched kernel it will return the same capability set as the unconfined run.
