Could you please let me know when the current set of changes in SELinux
next branch would be completed and be ready to take new changes?
I mean, roughly - would it be a month from now or you expect that to
take longer?
I can't speak for Paul but I would expect it to be sooner rather than
later. Ondrej has some follow ups on top of my policy rcu conversion
but then it should be good to go.
I think the major changes are now merged although there are still a
couple of changes coming from Ondrej that could affect your code. For
your purposes, the important things to note are:
1) The mutex has moved from selinux_fs_info to selinux_state and is
now named policy_mutex. You will need to take it around your call to
security_read_policy_kernel().
2) security_policydb_len() was removed and security_read_policy() just
directly reads the policydb len. You can do the same from your
security_read_policy_kernel() variant.
3) Ondrej has a pending change to move the policycap[] array from
selinux_state to selinux_policy so that it can be atomically updated
with the policy.
4) Ondrej has a pending change to eliminate the separate initialized
boolean from selinux_state and just test whether selinux_state.policy
is non-NULL but as long as you are using selinux_initialized() to
test, your code should be unaffected.
Thanks a lot for the update Stephen.
I will start updating the IMA measurement changes in selinux next
branch. Will post the patches this week.
