crypto: scomp - Drop the dst scratch buffer

As deflate has been converted over to acomp, and cavium zip has been removed, there are no longer any scomp algorithms that can be used by IPsec. Since IPsec was the only user of the dst scratch buffer, remove it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

- * This needs to be fixed so that the amount of memory required is properly

- *
- * The default winbits of 11 should suit most packets, and it may be something
- * to configure on a per-tfm basis in the future.
- *
- * Currently, compression history is not maintained between tfm calls, as
- * it is not needed for IPCOMP and keeps the code simpler.  It can be

Herbert Xu	324216a6b8	crypto: scomp - Drop the dst scratch buffer As deflate has been converted over to acomp, and cavium zip has been removed, there are no longer any scomp algorithms that can be used by IPsec. Since IPsec was the only user of the dst scratch buffer, remove it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2025-03-22 07:28:55 +08:00

Herbert Xu	b9ee7aacd4	crypto: deflate - Convert to acomp This is based on work by Ard Biesheuvel <ardb@kernel.org>. Convert deflate from scomp to acomp. This removes the need for the caller to linearise the source and destination.

Herbert Xu	a545074ee7	crypto: scomp - Allocate per-cpu buffer on first use of each CPU Per-cpu buffers can be wasteful when the number of CPUs is large, especially if the buffer itself is likely to never be used. Reduce such wastage by only allocating them on first use of a particular CPU. On start-up allocate a single buffer on the first possible CPU. For every other CPU a work struct will be scheduled on first use to allocate the buffer for that CPU. Until the allocation succeeds simply use the first CPU's buffer which is protected under a spin lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2025-03-22 07:28:54 +08:00
Herbert Xu	51768a21f4	crypto: api - Ensure cra_type->destroy is done in process context Move the cra_type->destroy call out of crypto_alg_put and into crypto_unregister_alg and crypto_free_instance. This ensures that it's always done in process context so calls such as flush_work can be done. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2025-03-22 07:28:54 +08:00
Herbert Xu	d24f97c031	crypto: api - Move alg destroy work from instance to template Commit `9ae4577bc0` ("crypto: api - Use work queue in crypto_destroy_instance") introduced a work struct to free an instance after the last user goes away. Move the delayed work from the instance into its template so that when the template is unregistered it can ensure that all its instances have been freed before returning.
