crypto: ahash - Fix EINPROGRESS notification callback

2017-04-21T07:30:06Z

commit ef0579b64e93188710d48667cb5e014926af9f1b upstream. The ahash API modifies the request's callback function in order to clean up after itself in some corner cases (unaligned final and missing finup). When the request is complete ahash will restore the original callback and everything is fine. However, when the request gets an EBUSY on a full queue, an EINPROGRESS callback is made while the request is still ongoing. In this case the ahash API will incorrectly call its own callback. This patch fixes the problem by creating a temporary request object on the stack which is used to relay EINPROGRESS back to the original completion function. This patch also adds code to preserve the original flags value. Fixes: ab6bf4e5e5e4 ("crypto: hash - Fix the pointer voodoo in...")

crypto: ghash-generic - move common definitions to a new header file

2016-10-22T10:26:56Z

commit a397ba829d7f8aff4c90af3704573a28ccd61a59 upstream. Move common values and types used by ghash-generic to a new header file so drivers can directly use ghash-generic as a fallback implementation.

crypto: af_alg - Add nokey compatibility path

2016-02-17T20:31:03Z

crypto: af_alg - Disallow bind/setkey/... after accept(2)

2016-02-17T20:31:02Z

commit c840ac6af3f8713a71b4d2363419145760bd6044 upstream. Each af_alg parent socket obtained by socket(2) corresponds to a tfm object once bind(2) has succeeded. An accept(2) call on that parent socket creates a context which then uses the tfm object. Therefore as long as any child sockets created by accept(2) exist the parent socket must not be modified or freed. This patch guarantees this by using locks and a reference count on the parent socket. Any attempt to modify the parent socket will fail with EBUSY.

KEYS: Merge the type-specific data with the payload data

2015-10-21T14:18:36Z

Merge the type-specific data with the payload data into one four-word chunk as it seems pointless to keep them separate. Use user_key_payload() for accessing the payloads of overloaded user-defined keys.
