Description: glibc's __get_nprocs() now checks /sys/devices/system/cpu/online
in addition to /proc/stat for the number of processors. This is used in the
_SC_NPROCESSORS_ONLN implementation, a part of sysconf. This was introduced in
upstream glibc commit:

This patch changes ~/.kde/ to ~/.kde{,4} in all abstractions.
The patch is mostly from Velery Valery, I only fixed a merge conflict

A bug in Ubuntu reported that the aspell abstraction does
not allow write access to the user customizable dictionaries, the
personal dictionary (~/.aspell.$LANG.pws) and the personal replacement
dictionary (~/.aspell.$LANG.prepl). It also adjusts the abstraction
to add the owner modifier to the personal dictionaries.

Profile loads when specifying namespaces currently conflict with caching.
If the profile (ignoring the specified namespace) is in the cache, then
the cached profile will be loaded, replacing the profile in the current
namespace instead of loading the profile to the new namespace.
Fix this by disabling caching when a namespace is specified, forcing the
profile to be compiled.
NOTE: this will not affect profiles loaded from within a namespace using
either the same or a separate directory as the base to load a namespac
from. This only affects loading profiles directly into a child
namespace.

The behavior for revalidation/revocation of open files has changed
with the current kernel code, resulting in these tests being reported
as failing even though they are showing expected behavior.
Under the current kernel module this form of revalidation/revocation
can not be tested reliably, so just changing the expected result is
not enough, completely disable the tests for now.

Lenient profile that is intended to be used when 'Ux' is desired but
does not provide enough environment sanitizing. This effectively is an
open profile that blacklists certain known dangerous files and also
does not allow any capabilities. For example, it will not allow 'm' on files
owned be the user invoking the program. While this provides some additional
protection, please use with care as applications running under this profile
are effectively running without any AppArmor protection. Use this profile
only if the process absolutely must be run (effectively) unconfined.
Limitations:
1. This does not work for root owned processes, because of the way we use
owner matching in the sanitized helper. We could do a better job with
this to support root, but it would make the policy harder to understand
and going unconfined as root is not desirable anyway.
2. For this sanitized_helper to work, the program running in the sanitized
environment must open symlinks directly in order for AppArmor to mediate
it. This is confirmed to work with:
- compiled code which can load shared libraries
- python imports
It is known not to work with:
- perl includes
3. Going forward it might be useful to try sanitizing ruby and java
Use at your own risk. This profile was developed as an interim workaround for
LP: #851986 until AppArmor implements proper environment filtering.

The commit also adds a new profile for usr.sbin.smbldap-useradd (based on
the audit.log from Alexis Pellicier).
Additionally, I moved the "/etc/samba/* rwk" rule next to the other
/etc-related rules in the smbd profile.

"[P11-KIT] Provides a way to load and enumerate PKCS#11 modules. Provides a
standard configuration setup for installing PKCS#11 modules in such a way that
they're discoverable."
File locatations are described in [1]. There is a global configuration file in
/etc/pkcs11/pkcs11.conf. Per module configuration happens in
/etc/pkcs11/<module name>. There is also user configuration in ~/.pkcs11, but
IMO this should not be allowed in the abstraction. Example configuration can be
seen in the upstream documentation[2].
This will likely need to be refined as more applications use p11-kit.
