crypto: algif_skcipher - Fix stream cipher chaining

2023-12-08T03:59:46+00:00

Unlike algif_aead which is always issued in one go (thus limiting the maximum size of the request), algif_skcipher has always allowed unlimited input data by cutting them up as necessary and feeding the fragments to the underlying algorithm one at a time. However, because of deficiencies in the API, this has been broken for most stream ciphers such as arc4 or chacha. This is because they have an internal state in addition to the IV that must be preserved in order to continue processing. Fix this by using the new skcipher state API. Signed-off-by: Herbert Xu

sock: Remove ->sendpage*() in favour of sendmsg(MSG_SPLICE_PAGES)

2023-06-24T22:50:13+00:00

Remove ->sendpage() and ->sendpage_locked(). sendmsg() with MSG_SPLICE_PAGES should be used instead. This allows multiple pages and multipage folios to be passed through.

crypto: af_alg: Support MSG_SPLICE_PAGES

2023-06-08T11:42:34+00:00

Make AF_ALG sendmsg() support MSG_SPLICE_PAGES. This causes pages to be spliced from the source iterator. This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction. Signed-off-by: David Howells cc: Herbert Xu cc: "David S.

Use extract_iter_to_sg() to decant the destination iterator into a scatterlist in af_alg_get_rsgl(). af_alg_make_sg() can then be removed. Signed-off-by: David Howells cc: Herbert Xu cc: "David S.

crypto: algif_skcipher - EBUSY on aio should be an error

2020-08-21T04:45:26+00:00

I removed the MAY_BACKLOG flag on the aio path a while ago but the error check still incorrectly interpreted EBUSY as success. This may cause the submitter to wait for a request that will never complete. Fixes: dad419970637 ("crypto: algif_skcipher - Do not set...") Signed-off-by: Herbert Xu

Pull crypto fix from Herbert Xu: "This fixes a regression in af_alg" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: algif_aead - fix uninitialized ctx->init

crypto: algif_aead - fix uninitialized ctx->init

2020-08-13T07:09:32+00:00

In skcipher_accept_parent_nokey() the whole af_alg_ctx structure is cleared by memset() after allocation, so add such memset() also to aead_accept_parent_nokey() so that the new "init" field is also initialized to zero. Without that the initial ctx->init checks might randomly return true and cause errors. While there, also remove the redundant zero assignments in both functions. Found via libkcapi testsuite.
