crypto: af_alg - Allow af_af_alg_release_parent to be called on nokey path

2016-02-13T10:34:12Z

commit 6a935170a980024dd29199e9dbb5c4da4767a1b9 upstream. This patch allows af_alg_release_parent to be called even for nokey sockets. Signed-off-by: Herbert Xu Signed-off-by: Ben Hutchings

crypto: hash - Add crypto_ahash_has_setkey

2016-02-13T10:34:12Z

commit a5596d6332787fd383b3b5427b41f94254430827 upstream. This patch adds a way for ahash users to determine whether a key is required by a crypto_ahash transform. Signed-off-by: Herbert Xu [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

crypto: af_alg - Add nokey compatibility path

2016-02-13T10:34:12Z

commit 37766586c965d63758ad542325a96d5384f4a8c9 upstream. This patch adds a compatibility path to support old applications that do acept(2) before setkey. Signed-off-by: Herbert Xu [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

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

2016-02-13T10:34:11Z

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.

crypto: scatterwalk - Use sg_chain_ptr on chain entries

2014-01-03T04:33:29Z

commit 389a5390583a18e45bc4abd4439291abec5e7a63 upstream. Now that scatterwalk_sg_chain sets the chain pointer bit the sg_page call in scatterwalk_sg_next hits a BUG_ON when CONFIG_DEBUG_SG is enabled. Use sg_chain_ptr instead of sg_page on a chain entry.

crypto: scatterwalk - Set the chain pointer indication bit

2014-01-03T04:33:26Z

commit 41da8b5adba77e22584f8b45f9641504fa885308 upstream. The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain function to chain two scatterlists, but the chain pointer indication bit is not set. When the resulting scatterlist is used, for example, by sg_nents to count the number of scatterlist entries, a segfault occurs because sg_nents does not follow the chain pointer to the chained scatterlist. Update scatterwalk_sg_chain to set the chain pointer indication bit as is done by the sg_chain function. Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu Signed-off-by: Ben Hutchings

crypto: Add a report function pointer to crypto_type

2011-10-21T12:24:03Z

We add a report function pointer to struct crypto_type. This function pointer is used from the crypto userspace configuration API to report crypto algorithms to userspace. Signed-off-by: Steffen Klassert Signed-off-by: Herbert Xu

crypto: blowfish - split generic and common c code

2011-09-22T11:25:25Z

Patch splits up the blowfish crypto routine into a common part (key setup) which will be used by blowfish crypto modules (x86_64 assembly and generic-c). Also fixes errors/warnings reported by checkpatch. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

I guess you need to include crypto/hash.h in crypto/sha.h. This patch fixes this by providing a declaration for struct shash_desc. Reported-by: Stephen Rothwell Signed-off-by: Herbert Xu

crypto: sha1 - export sha1_update for reuse

2011-08-10T11:00:28Z

Export the update function as crypto_sha1_update() to not have the need to reimplement the same algorithm for each SHA-1 implementation. This way the generic SHA-1 implementation can be used as fallback for other implementations that fail to run under certain circumstances, like the need for an FPU context while executing in IRQ context.
