When "sepolicy manpage" generates descriptions for file type, it uses a
mispelled _ra_content_t suffix for prettyprinting, which results in an
unwanted double-space on the line.
For example sepolicy manpage -d httpd_t produces:
.EX
.P
.B httpd_apcupsd_cgi_ra_content_t
.EE
- Set files with the httpd_apcupsd_cgi_ra_content_t type, if you
want to treat the files as httpd apcupsd cgi read/append content.

SETools4 and Python 3 versions of map() and filter() uses iterators to
generates query results and these iterators can't be imply re-used. It
makes manpage and transitions operations really slow as they do lot of queries.
This patch changes it in the way that it caches results in lists for all
types, allow rules and transitions first and use cached results to
filter them using Python's filter() function.

As reported by Nicolas Iooss, there are still some inconsistencies
in the definitions and usage of Makefile variables related to bin
and sbin directories. Since we need to still support non-usrmerge
systems, we cannot completely synchronize them, but we can eliminate
unnecessary differences, remove unused variables, and drop the
USRSBINDIR variables.
Before:
$ find . -name Makefile -exec cat {} + |grep '^[A-Z_]*BINDIR' |sort -u
BINDIR=$(PREFIX)/bin
BINDIR ?= $(PREFIX)/bin
BINDIR ?= $(PREFIX)/sbin
SBINDIR ?= $(DESTDIR)/sbin
SBINDIR ?= $(PREFIX)/sbin
USRSBINDIR ?= $(PREFIX)/sbin
After:
$ find . -name Makefile -exec cat {} + | grep '^[A-Z_]*BINDIR' | sort -u
BINDIR ?= $(PREFIX)/bin
SBINDIR ?= $(DESTDIR)/sbin
SBINDIR ?= $(PREFIX)/sbin
This does not change the actual install location of any file.
It does drop the legacy symlink from /usr/sbin/load_policy to
/sbin/load_policy; packagers can create that separately if
desired.

After libsepol is modified (for example while developing new features or

After 9406ace8 ("libsemanage: throw exceptions in python rather than

instead of returning negative error return codes. For systems that did not
have the applicable headers installed prior to build, the difference was
not seen. Following commit 9792099f ("Properly build the swig exception
file even if the headers are missing"), that issue has been resolved and
the underlying semanage_fcontext_query_local and semanage_fcontext_query
calls now result in an OSError return. This results in the following error
when attempting to modify a fcontext defined in the systems base policy.
libsemanage.dbase_llist_query: could not query record value (No such file or directory).

Teach audit2why to recognize type bounds failures. This required
updating libsepol sepol_compute_av_reason() to identify bounds
failures, and updating libsepol context_struct_compute_av() to
include the type bounds logic from the kernel.
This could potentially be further augmented to provide more detailed
reporting via the reason buffer to include information similar to
what security_dump_masked_av() reports in the kernel. However, it
is unclear if this is needed. It is already possible to get type
bounds checking at policy build time by enabling expand-check=1
in /etc/selinux/semanage.conf (or by default when compiling
monolithic policy).
