Merge tag 'selinux-pr-20240513' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Attempt to pre-allocate the SELinux status page so it doesn't appear
   to userspace that we are skipping SELinux policy sequence numbers

 - Reject invalid SELinux policy bitmaps with an error at policy load
   time

 - Consistently use the same type, u32, for ebitmap offsets

 - Improve the "symhash" hash function for better distribution on common
   policies

 - Correct a number of printk format specifiers in the ebitmap code

 - Improved error checking in sel_write_load()

 - Ensure we have a proper return code in the
   filename_trans_read_helper_compat() function

 - Make better use of the current_sid() helper function

 - Allow for more hash table statistics when debugging is enabled

 - Migrate from printk_ratelimit() to pr_warn_ratelimited()

 - Miscellaneous cleanups and tweaks to selinux_lsm_getattr()

 - More consitification work in the conditional policy space
