User-visible changes

• libsepol implemented a new, more space-efficient form of storing filename
  transitions in the binary policy and reduced the size of the binary policy

• libselinux: Use mmap()'ed kernel status page instead of netlink by default.
  See "KERNEL STATUS PAGE" section in avc_init(3) for more details.
  Note: if you need to umount /sys/fs/selinux you need to use lazy umount -
  umount -l /sys/fs/selinux as the kernel status page /sys/fs/selinux/status
  stays mapped by processes like systemd, dbus, sshd.

• Tools using sepolgen, e.g. audit2allow, print extended permissions in
  hexadecimal

• sepolgen sorts extended rules like normal ones

• New log callback levels for enforcing and policy load notices -
  SELINUX_POLICYLOAD, SELINUX_SETENFORCE

• Changed userspace AVC setenforce and policy load messages to audit format.

• matchpathcon converted to selabel_lookup() - no more matchpathcon is
  deprecated warning

• libsepol and libsemanage dropped old and deprecated symbols and functions
  libsepol version was bumped to libsepol.so.2
  libsemanage version was bumped to libsemanage.so.2

• Release version for the whole project is same as for subcomponents, e.g.
  instead of 20210118 it's 3.2-rc1

• Improved usability of getseuser

• Fixed several issues in cil code found by OSS-FUZZ

• setfiles doesn't abort on labeling errors

• libsemanage tries to sync data to prevent empty files in SELinux module store

• Improved secilc documentation - fenced code blocks, syntax highlighting, custom
  color theme, ...

• Better error reporting in getconlist

• libsepol implemented a new, more space-efficient form of storing filename
  transitions in the binary policy and reduced the size of the binary policy

Development-relevant changes

• License the CI scripts with a permissive, OSI approved license, such as MIT

• Several CI improvements

• Added configuration to build and run tests in GitHub Actions

• CI contains configuration for a Vagrant virtual machine - instructions on how
  to use it are documented at the beginning of Vagrantfile.

Packaging-relevant changes

• Both libsepol and libsemanage bumped their soname versions. Especially
  libsemanage is linked to shadow-utils and direct update might cause problems to
  buildroots. Also SETools needs to be rebuilt against libsepol.so.2

• Source repository snapshot selinux-3.2-rc2.tar.gz is available on the release page

• sestatus is installed as /usr/bin/sestatus by default. Original /usr/sbin/sestatus is
  a relative symlink to the /usr/bin/sestatus.

Issues fixed

• #245
• #270

User-visible changes

• selinux/flask.h, selinux/av_permissions.h and sepol/policydb/flask.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 76913d8 ("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.

• Removed restrictions in libsepol and checkpolicy that required all declared
  initial SIDs to be assigned a context.

• Support for new policy capability 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

• 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

• checkpolicy treats invalid characters as an error - might break rare use cases (intentionally)

• New restorecon -x option which prevents it from crossing file system boundaries.

• Handle semanage module in semanage bash completion

• 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.

• 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 ...

Development-relevant changes

• Improved README which was renamed to README.md and converted to markdown.

• Added Travis CI job to run SELinux kernel testsuite on latest Fedora cloud image
