Pull selinux updates from Paul Moore:
- Add a new SELinux initial SID, SECINITSID_INIT, to represent
userspace processes started before the SELinux policy is loaded in
early boot.
Prior to this patch all processes were marked as SECINITSID_KERNEL
before the SELinux policy was loaded, making it difficult to
distinquish early boot userspace processes from the kernel in the
SELinux policy.
For most users this will be a non-issue as the policy is loaded early
enough during boot, but for users who load their SELinux policy
relatively late, this should make it easier to construct meaningful
security policies.
- Cleanups to the selinuxfs code by Al, mostly on VFS related issues
during a policy reload.
The commit description has more detail, but the quick summary is that
we are replacing a disconnected directory approach with a temporary
directory that we swapover at the end of the reload.
- Fix an issue where the input sanity checking on socket bind()
operations was slightly different depending on the presence of
SELinux.
This is caused by the placement of the LSM hooks in the generic
socket layer as opposed to the protocol specific bind() handler where
the protocol specific sanity checks are performed. Mickaƫl has
mentioned that he is working to fix this, but in the meantime we just
ensure that we are replicating the checks properly.
We need to balance the placement of the LSM hooks with the number of
LSM hooks; pushing the hooks down into the protocol layers is likely
not the right answer.
- Update the avc_has_perm_noaudit() prototype to better match the
function definition.
- Migrate from using partial_name_hash() to full_name_hash() the
filename transition hash table.
This improves the quality of the code and has the potential for a
minor performance bump.
- Consolidate some open coded SELinux access vector comparisions into a
single new function, avtab_node_cmp(), and use that instead.
A small, but nice win for code quality and maintainability.
- Updated the SELinux MAINTAINERS entry with additional information
around process, bug reporting, etc.
We're also updating some of our "official" roles: dropping Eric Paris
and adding Ondrej as a reviewer.
- Cleanup the coding style crimes in security/selinux/include.
While I'm not a fan of code churn, I am pushing for more automated
code checks that can be done at the developer level and one of the
obvious things to check for is coding style.
In an effort to start from a "good" base I'm slowly working through
our source files cleaning them up with the help of clang-format and
good ol' fashioned human eyeballs; this has the first batch of these
changes.
I've been splitting the changes up per-file to help reduce the impact
if backports are required (either for LTS or distro kernels), and I
expect the some of the larger files, e.g. hooks.c and ss/services.c,
will likely need to be split even further.
- Cleanup old, outdated comments.
