When kernel needs to write to RW pages, the associated # segment register is then changed to Ks 0 in order to allow write # access to the kernel. # # In order to avoid having the read all segment registers when # locking/unlocking the access, some data is kept in the thread_struct # and saved on stack on exceptions. The field identifies both the # first unlocked segment and the first segment following the last # unlocked one. When no segment is unlocked, it contains value 0. # # As the hash_page() function is not able to easily determine if a # protfault is due to a bad kernel access to userspace, protfaults # need to be handled by handle_page_fault when KUAP is set. # # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # [mpe: Drop allow_read/write_to/from_user() as they're now in kup.h, # and adapt allow_user_access() to do nothing when to == NULL] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # <
