Modified files:
sys/kern kern_jail.c
sys/sys jail.h
Log:
Implement functionality I called 'jail services'.
It may be used for external modules to attach some data to jail's in-kernel
structure.
- Change allprison_mtx mutex to allprison_sx sx(9) lock.
We will need to call external functions while holding this lock, which may
want to allocate memory.
Make use of the fact that this is shared-exclusive lock and use shared
version when possible.
- Implement the following functions:
prison_service_register() - registers a service that wants to be noticed
when a jail is created and destroyed
prison_service_deregister() - deregisters service
prison_service_data_add() - adds service-specific data to the jail structure
prison_service_data_get() - takes service-specific data from the jail
structure
prison_service_data_del() - removes service-specific data from the jail
structure
