Paul Moore d7cf3412a9 lsm: consolidate buffer size handling into lsm_fill_user_ctx() ... While we have a lsm_fill_user_ctx() helper function designed to make life easier for LSMs which return lsm_ctx structs to userspace, we didn't include all of the buffer length safety checks and buffer padding adjustments in the helper. This led to code duplication across the different LSMs and the possibility for mistakes across the different LSM subsystems. In order to reduce code duplication and decrease the chances of silly mistakes, we're consolidating all of this code into the lsm_fill_user_ctx() helper. The buffer padding is also modified from a fixed 8-byte alignment to an alignment that matches the word length of the machine (BITS_PER_LONG / 8).
