Subject: libsepol: fix boolean state smashing
Date: Wed, 18 Mar 2009 10:47:34 -0400
If a boolean is encountered in a require block before the place where it is
declared it currently gets created with the state set to false no matter what
the declared state was. This only affects booleans in modules where the boolean
was also required in another module. Patch below:

windows with selinux running. Part of the reason for this was because
libselinux called into the kernel /selinux/create interface for every
object. This patch caches the results of /selinux/create in the
userspace avc to significantly increase the speed of these types of
operations.
Revised to correct locking, interface issues.

Init script should be 755
libflashplayer.so has moved in the homedir and is now correct so no
longer needs to have labeling checked.
restorecond supports glob matching and should not complain on multiple
hard links if they match a glob.
So if a file has > 1 link and is an exact match complain, otherwise do not.
Also fix a couple of error messages.

The boundry format mapped the primary field to a boolean in the
properties bitmap. This is appropriate for the kernel policy, but in
modular policy the primary field may be an integer that indicates the
primary type that is being aliased. In this case, the primary value cannot
be assumed to be boolean.
This patch creates a new module format that writes out the primary value
as was done before the boundry format.

And this is still broken.
One more fix.

Change semanage/seobject to use semanage_mls_enabled() rather than
is_selinux_mls_enabled(). I dropped the mls enabled tests altogether
from the semanage front-end script since setting up a handle is done by
seobject.py; if those checks are actually important, we could move them
inside of the seobject methods, but I'm not clear on the real benefit of
those checks. In seobject.py, I moved the setting of the is_mls_enabled
variable inside of get_handle(store) after the connect. I also dropped
the is_mls_enabled test from setransRecords since no handle/connection
exists there (since translations are not managed via libsemanage), and
again I'm not clear that the check there was overly important/useful.

Add a semanage_mls_enabled() interface to libsemanage so that
semanage/seobject can be rewritten to use it to test whether MLS is
enabled for a given policy store rather than checking the runtime MLS
enabled status, which can be misleading when using semanage on a
SELinux-disabled host or when using semanage on a store other than the
active one. Sample usage:
from semanage import *
handle = semanage_handle_create()
rc = semanage_connect(handle)
rc = semanage_mls_enabled(handle)
Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>
The current libsemanage code does not correctly add lines which include
USER in them into the homedir_template, for example:
/tmp/gconfd-USER -d system_u:object_r:ROLE_tmp_t
This line was included in the past since it has ROLE. However, with the
switch to UBAC separations, the line has changed to:
/tmp/gconfd-USER -d system_u:object_r:user_tmp_t
and is no longer included. The follwing patch fixes.
