crypto: cavium/zip - Remove driver

2025-04-07T05:22:25Z

Remove cavium/zip as it is obsolete and stands in the way of acomp API work. If this is ever resurrected, please turn it into an acomp driver. Signed-off-by: Herbert Xu

crypto: cavium/zip - drop obsolete 'comp' implementation

2025-03-21T09:39:06Z

The 'comp' API is obsolete and will be removed, so remove this comp implementation. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: scomp - Remove tfm argument from alloc/free_ctx

2025-03-15T08:21:22Z

The tfm argument is completely unused and meaningless as the same stream object is identical over all transforms of a given algorithm. Remove it. Signed-off-by: Herbert Xu

crypto: zip - remove the unneeded result variable

2022-09-30T05:57:50Z

Return the value directly instead of storing it in another redundant variable. Reported-by: Zeal Robot Signed-off-by: ye xingchen Signed-off-by: Herbert Xu

crypto: cavium/zip - register algorithm only if hardware is present

2022-03-02T22:46:19Z

On my renesas salavator-X, I saw some cavium driver failing crypto self-tests. But salvator does not have such hardware. This is due to cavium/zip driver registering algorithms even if hardware is not present. The solution is to move algorithm registration in the probe function. This permits also to simplify module init/exit by using module_pci_driver. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: cavium/zip - remove unused including

2021-04-16T11:16:32Z

Remove including that don't need it. Signed-off-by: Tian Tao Signed-off-by: Zhiqi Song Signed-off-by: Herbert Xu

crypto: cavium/zip - Use dma_set_mask_and_coherent to simplify code

2020-11-27T06:13:47Z

'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose. Signed-off-by: Christophe JAILLET Signed-off-by: Herbert Xu

crypto: cavium/zip - Convert to DEFINE_SHOW_ATTRIBUTE

2020-09-25T07:48:16Z

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code. Signed-off-by: Qinglang Miao Signed-off-by: Herbert Xu

mm, treewide: rename kzfree() to kfree_sensitive()

2020-08-07T18:33:22Z

As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.

crypto: cavium/zip - Add missing single_release()

2019-09-09T13:48:41Z

When using single_open() for opening, single_release() should be used instead of seq_release(), otherwise there is a memory leak. Fixes: 09ae5d37e093 ("crypto: zip - Add Compression/Decompression statistics") Cc: Signed-off-by: Wei Yongjun Signed-off-by: Herbert Xu
