crypto: remove obsolete 'comp' compression API

2025-03-21T09:39:06Z

The 'comp' compression API has been superseded by the acomp API, which is a bit more cumbersome to use, but ultimately more flexible when it comes to hardware implementations. Now that all the users and implementations have been removed, let's remove the core plumbing of the 'comp' API as well. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: compress - remove crt_u.compress (struct compress_tfm)

2019-12-11T08:37:01Z

crt_u.compress (struct compress_tfm) is pointless because its two fields, ->cot_compress() and ->cot_decompress(), always point to crypto_compress() and crypto_decompress(). Remove this pointless indirection, and just make crypto_comp_compress() and crypto_comp_decompress() be direct calls to what used to be crypto_compress() and crypto_decompress(). Also remove the unused function crypto_comp_cast(). Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: api - Remove no-op exit_ops code

2016-10-21T03:03:42Z

crypto_exit_cipher_ops() and crypto_exit_compress_ops() are no-ops and have been for a long time, so remove them. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

cleanup asm/scatterlist.h includes

2007-11-02T07:47:06Z

Not architecture specific code should not #include . This patch therefore either replaces them with #include or simply removes them if they were unused. Signed-off-by: Adrian Bunk Signed-off-by: Jens Axboe

[CRYPTO] api: Added cra_init/cra_exit

2006-06-26T07:34:40Z

This patch adds the hooks cra_init/cra_exit which are called during a tfm's construction and destruction respectively. This will be used by the instances to allocate child tfm's. For now this lets us get rid of the coa_init/coa_exit functions which are used for exactly that purpose (unlike the dia_init function which is called for each transaction). In fact the coa_exit path is currently buggy as it may get called twice when an error is encountered during initialisation. Signed-off-by: Herbert Xu

[CRYPTO] api: Fixed incorrect passing of context instead of tfm

[CRYPTO] all: Pass tfm instead of ctx to algorithms

2006-06-26T07:34:39Z

Up until now algorithms have been happy to get a context pointer since they know everything that's in the tfm already (e.g., alignment, block size). However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h. Signed-off-by: Herbert Xu
