Currently, handle_sepolicy() holds an RCU read lock across the entire
function including calls to strncpy_from_user() which can sleep, which
is illegal in RCU semantics.
This triggers the following warning when the kernel is compiled with
CONFIG_DEBUG_ATOMIC_SLEEP enabled:
[ 8.526345] BUG: sleeping function called from invalid context at lib/strncpy_from_user.c:40

To fix this, replace the rcu_read_lock() with the `ksu_rules` mutex_lock()
introduced with commit 9014c66 ("kernel: selinux: rules: Fix illegal RCU
lock usage in apply_kernelsu_rules()") which allows sleeping.
This mutex_lock() ensures mutual exclusion between threads invoking dynamic
policy modifications via handle_sepolicy() and those applying KernelSU rules
via apply_kernelsu_rules(), both of which access the policydb structure through
get_policydb().

…icydb() get_policydb() uses rcu_dereference() to read pointers to selinux_state.policy. But in the SELinux implementation, these pointers are assigned once during initialization and never changed with rcu_assign_pointer(), rendering the rcu_dereference() call in get_policydb() completely useless. This just adds unwanted overhead and implies concurrency pattern that is not even present in the kernel. Therefore, read the pointers directly since it's safe.

This commit restores compatibility code needed for legacy that was removed upstream. Restores LSM hooks: - inode_rename - replacss pkg_observer.c - task_fix_setuid - replaces setuid_hook.c + kernel_umount.c Restores workqueue'd allowlist handling dropped at bfb767b, 9060e61 Restores -Wno-implicit-function-declaration dropped at d3a09fa Restores old core_hook infrastructure. breaking it up to setuid + kernel_umount is just more complexity here.
