I'd like to release 3.1 today/tommorow to open the development of other
performance related improvemenets which which postponed. This is release notes
draft which is based on RELEASE-20200518.txt and RELEASE-20200619.txt:
RELEASE 202007XX (3.1)
User-visible changes:
* selinux/flask.h and selinux/av_permissions.h were removed
The flask.h and av_permissions.h header files were deprecated and
all selinux userspace references to them were removed in
commit 76913d8adb61b5 ("Deprecate use of flask.h and av_permissions.h.")
back in 2014 and included in the 20150202 / 2.4 release.
All userspace object managers should have been updated
to use the dynamic class/perm mapping support since that time.
Remove these headers finally to ensure that no users remain and
that no future uses are ever introduced.
Use string_to_security_class(3) and string_to_av_perm(3) to map the class and
permission names to their policy values, or selinux_set_mapping(3) to create a
mapping from class and permission index values used by the application to the
policy values.
* Support for new polcap genfs_seclabel_symlinks
* New `setfiles -E` option - treat conflicting specifications as errors, such
as where two hardlinks for the same inode have different contexts.
* `restorecond_user.service` - new systemd user service which runs `restorecond -u`
* `setsebool -V` reports errors from commit phase
* Improved man pages
* `semanage` uses ipaddress Python module instead of IPy
* matchpathcon related interfaces are deprecated
* selinuxfs is mounted with noexec and nosuid
* Improved README which was renamed to README.md and converted to markdown.
* `setup.py` builds can be customized using PYTHON_SETUP_ARGS, e.g. to for
Debian Python layout use: `make PYTHON_SETUP_ARGS=--install-layout=deb ...`
* the dso wrappers for internal calls were removed and it is now strongly recommended to CFLAGS with
`-fno-semantic-interposition`
* `security_compute_user()` was deprecated - usage of /sys/fs/selinux/user { security:compute_user } might be revisited
* checkpolicy treats invalid characters as an error - it might break (but intentional) rare use cases
* New `restorecon -x` option - prevent `restorecon` from crossing file system
boundaries.
* Handle `semanage module` in semanage bash completion
* Added section about CFLAGS to README.md, see Packaging-relevant changes
* Improved man pages
* Add Travis CI job to run SELinux kernel testsuite on latest Fedora cloud image
* `sepolgen-ifgen` parses a gen_tunable statement as bool
* `semanage` handles getprotobyname() failure case on Debian where /etc/protocols does not contain an entry for "ipv4"
Packaging-relevant changes:
* Setting CFLAGS during the make process will cause the omission of many defaults. While the project strives
to provide a reasonable set of default flags, custom CFLAGS could break the build, or have other undesired
changes on the build output. Thus, be very careful when setting CFLAGS. CFLAGS that are encouraged to be
set when overriding are:
- -fno-semantic-interposition for gcc or compilers that do not do this. clang does this by default. clang-10 and up
will support passing this flag, but ignore it. Previous clang versions fail.
