crypto: Add userspace configuration API

2011-10-21T12:24:03Z

This patch adds a basic userspace configuration API for the crypto layer. With this it is possible to instantiate, remove and to show crypto algorithms from userspace. Signed-off-by: Steffen Klassert Signed-off-by: Herbert Xu

crypto: blowfish - rename C-version to blowfish_generic

2011-09-22T11:25:26Z

Rename blowfish to blowfish_generic so that assembler versions of blowfish cipher can autoload. Module alias 'blowfish' is added. Also fix checkpatch warnings. Signed-off-by: Jussi Kivilinna 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

crypto: authencesn - Add algorithm to handle IPsec extended sequence numbers

2011-03-14T03:22:27Z

ESP with separate encryption/authentication algorithms needs a special treatment for the associated data. This patch add a new algorithm that handles esp with extended sequence numbers. Signed-off-by: Steffen Klassert Acked-by: Herbert Xu Signed-off-by: David S. Miller

crypto: Makefile clean up

2010-11-27T08:32:57Z

Changed Makefile to use -y instead of -objs. Signed-off-by: Tracey Dent Signed-off-by: Herbert Xu

crypto: algif_skcipher - User-space interface for skcipher operations

2010-11-26T12:53:59Z

This patch adds the af_alg plugin for symmetric key ciphers, corresponding to the ablkcipher kernel operation type. Keys can optionally be set through the setsockopt interface. Once a sendmsg call occurs without MSG_MORE no further writes may be made to the socket until all previous data has been read. IVs and and whether encryption/decryption is performed can be set through the setsockopt interface or as a control message to sendmsg. The interface is completely synchronous, all operations are carried out in recvmsg(2) and will complete prior to the system call returning. The splice(2) interface support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). The recvmsg(2) interface supports directly writing to user-space without additional copying, i.e., the kernel crypto interface will receive the user-space address as its output SG list. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements. Signed-off-by: Herbert Xu Acked-by: David S. Miller

crypto: algif_hash - User-space interface for hash operations

2010-11-19T09:47:58Z

This patch adds the af_alg plugin for hash, corresponding to the ahash kernel operation type. Keys can optionally be set through the setsockopt interface. Each sendmsg call will finalise the hash unless sent with a MSG_MORE flag. Partial hash states can be cloned using accept(2). The interface is completely synchronous, all operations will complete prior to the system call returning. Both sendmsg(2) and splice(2) support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). For now only the splice(2) interface supports performing digest instead of init/update/final. In future the sendmsg(2) interface will also be modified to use digest/finup where possible so that hardware that cannot return a partial hash state can still benefit from this interface. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements. Signed-off-by: Herbert Xu Acked-by: David S. Miller Tested-by: Martin Willi

crypto: af_alg - User-space interface for Crypto API

2010-11-19T09:47:57Z

This patch creates the backbone of the user-space interface for the Crypto API, through a new socket family AF_ALG. Each session corresponds to one or more connections obtained from that socket. The number depends on the number of inputs/outputs of that particular type of operation. For most types there will be a s ingle connection/file descriptor that is used for both input and output. AEAD is one of the few that require two inputs. Each algorithm type will provide its own implementation that plugs into af_alg. They're keyed using a string such as "skcipher" or "hash". IOW this patch only contains the boring bits that is required to hold everything together. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements.

crypto: twofish: Rename twofish to twofish_generic and add an alias

2010-06-03T11:02:51Z

This fixes the broken autoloading of the corresponding twofish assembler ciphers on x86 and x86_64 if they are available. The module name of the generic implementation was in conflict with the alias in the assembler modules. The generic twofish c implementation is renamed to twofish_generic according to the other algorithms with assembler implementations and an module alias is added for 'twofish'. You can now load 'twofish' giving you the best implementation by priority, 'twofish-generic' to get the c implementation or 'twofish-asm' to get the assembler version of cipher.

crypto: pcomp - Fix illegal Kconfig configuration

2010-06-03T10:33:06Z

The PCOMP Kconfig entry current allows the following combination which is illegal: ZLIB=y PCOMP=y ALGAPI=m ALGAPI2=y MANAGER=m MANAGER2=m This patch fixes this by adding PCOMP2 so that PCOMP can select ALGAPI to propagate the setting to MANAGER2. Signed-off-by: Herbert Xu
