Subject: [PATCH] libselinux: add missing av_permission values
|
||||||
|
|
||||||
|
Add missing av_permission values to av_permissions.h for the sake of
|
||||||
|
completeness (this interface is obsolete - these values are now
|
||||||
|
obtained at runtime).
|
||||||

Subject: [PATCH] libselinux: Use Python distutils to install SELinux python
|
||||||
|
bindings
|
||||||
|
|
||||||
|
SWIG-4.0 changed its behavior so that it uses: from . import _selinux which
|
||||||
|
looks for _selinux module in the same directory as where __init__.py is -
|
||||||
|
$(PYLIBDIR)/site-packages/selinux. But _selinux module is installed into
|
||||||
|
$(PYLIBDIR)/site-packages/ since a9604c30a5e2f ("libselinux: Change the location
|
||||||
|
of _selinux.so").
|
||||||
|
|
||||||
|
In order to prevent such breakage in future use Python's distutils instead of
|
||||||
|
building and installing python bindings manually in Makefile.
|
||||||
|
|
||||||
|
Fixes:
|
||||||
|

Subject: [PATCH] Fix mcstrans secolor examples
|
||||||
|
|
||||||
|
According to "check_dominance" function:
|
||||||
|
Range defined as "s15:c0.c1023" does not dominate any other range than
|
||||||
|
"s15:c0.c1023" (does not dominate "s15", "s15:c0.c200", etc.).
|
||||||
|
While range defined as "s15-s15:c0.c1023" dominates all of the above.
|
||||||
|
|
||||||
|
This is either a bug, or "s15:c0.c1023" should not be used in the
|
||||||
|
examples.

Subject: [PATCH] libselinux: Eliminate use of security_compute_user()
|
||||||
|
|
||||||
|
get_ordered_context_list() code used to ask the kernel to compute the complete
|
||||||
|
set of reachable contexts using /sys/fs/selinux/user aka
|
||||||
|
security_compute_user(). This set can be so huge so that it doesn't fit into a
|
||||||
|
kernel page and security_compute_user() fails. Even if it doesn't fail,
|
||||||
|
get_ordered_context_list() throws away the vast majority of the returned
|
||||||
|
contexts because they don't match anything in
|
||||||
|
/etc/selinux/targeted/contexts/default_contexts or
|
||||||
|
/etc/selinux/targeted/contexts/users/
|
||||||
|
|
||||||
|
get_ordered_context_list() is rewritten to compute set of contexts based on
|
||||||
|
/etc/selinux/targeted/contexts/users/ and
|
||||||
|
/etc/selinux/targeted/contexts/default_contexts files and to return only valid
|
||||||
|
contexts, using security_check_context(), from this set.
|
||||||

Subject: [PATCH] libselinux: deprecate security_compute_user(), update man
|
||||||
|
pages
|
||||||
|
|
||||||
|
commit 1f89c4e7879fcf6da5d8d1b025dcc03371f30fc9 ("libselinux: Eliminate
|
||||||
|
use of security_compute_user()") eliminated the use of
|
||||||
|
security_compute_user() by get_ordered_context_list(). Deprecate
|
||||||
|
all use of security_compute_user() by updating the headers and man
|
||||||
|
pages and logging a warning message on any calls to it. Remove
|
||||||
|
the example utility that called the interface. While here, also
|
||||||
|
fix the documentation of correct usage of the user argument to these
|
||||||
|
interfaces.
