From 4a7794860ba2b56693b1d89fd485fd08cdc763e3 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 13 Sep 2008 18:19:03 -0700 Subject: crypto: api - Move type exit function into crypto_tfm The type exit function needs to undo any allocations done by the type init function. However, the type init function may differ depending on the upper-level type of the transform (e.g., a crypto_blkcipher instantiated as a crypto_ablkcipher). So we need to move the exit function out of the lower-level structure and into crypto_tfm itself. As it stands this is a no-op since nobody uses exit functions at all. However, all cases where a lower-level type is instantiated as a different upper-level type (such as blkcipher as ablkcipher) will be converted such that they allocate the underlying transform and use that instead of casting (e.g., crypto_ablkcipher casted into crypto_blkcipher). That will need to use a different exit function depending on the upper-level type. This patch also allows the type init/exit functions to call (or not) cra_init/cra_exit instead of always calling them from the top level.
