If you've got SELinux policy loaded, label_hnd is your labeling handle.
When systemd is shutting down, we free that handle via mac_selinux_finish().
But: switch_root() calls mkdir_p_label(), which tries to look up a label
using that freed handle, and so we get a bunch of garbage and eventually
SEGV in libselinux.
(This doesn't happen in the switch-root from initramfs to real root because
there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we
never attempt any lookups.)
So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so
nobody tries to use it after it becomes invalid.

Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
|
|
This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

We need original socket_fd around otherwise mac_selinux_get_child_mls_label
fails with -EINVAL return code. Also don't call setexeccon twice but rather pass
context value of SELinuxContext option as an extra argument.
|
|
The SELinux policy defines no context for some files. E.g.:
$ matchpathcon /run/lock/subsys /dev/mqueue
/run/lock/subsys <<none>>
/dev/mqueue <<none>>
We still need to be able to create them.
In this case selabel_lookup_raw() returns ENOENT. We should then skip
setfscreatecon(), but still return success.
It was broken since c34255bdb2 ("label: unify code to make directories,
symlinks").

Normally we shouldn#t log from "library" functions, but SELinux is
weird, hence upgrade security messages uniformly to LOG_ERR when in
enforcing mode.

APIs that query and return something cannot silently fail, they must
either return something useful, or an error. Fix that.
Also, properly rollback socket unit fd creation when something goes
wrong with the security framework.

move label apis to selinux-util.ch or smack-util.ch appropriately.
|

Always cache the results, and bypass low-level security calls when the
respective subsystem is not enabled.

a) Instead of parsing the bus messages inside of selinux-access.c
simply pass everything pre-parsed in the functions
b) implement the access checking with a macro that resolves to nothing
on non-selinux builds
c) split out the selinux checks into their own sources
selinux-util.[ch]
d) this unifies the job creation code behind the D-Bus calls
Manager.StartUnit() and Unit.Start().
