crypto: mv_cesa requires on CRYPTO_HASH to build

2012-05-21T16:40:03Z

commit 1ebfefcf37a6e308266a8d786e8cfea0a454058c upstream. Without CRYPTO_HASH being selected, mv_cesa has a lot of hooks into undefined exports. ---- MODPOST 81 modules Kernel: arch/arm/boot/Image is ready AS arch/arm/boot/compressed/head.o GZIP arch/arm/boot/compressed/piggy.gzip CC arch/arm/boot/compressed/misc.o CC arch/arm/boot/compressed/decompress.o ERROR: "crypto_ahash_type" [drivers/crypto/mv_cesa.ko] undefined!

crypto: mv_cesa - fix final callback not ignoring input data

2012-03-12T17:32:56Z

commit f8f54e190ddb4ed697036b60f5e2ae6dd45b801c upstream. Broken by commit 6ef84509f3d439ed2d43ea40080643efec37f54f for users passing a request with non-zero 'nbytes' field, like e.g. testmgr. Signed-off-by: Phil Sutter Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: mv_cesa - fix hashing of chunks > 1920 bytes

2011-12-09T16:52:20Z

commit 274252862f386b7868f35bf5ceaa5391a8ccfdf3 upstream. This was broken by commit 7759995c75ae0cbd4c861582908449f6b6208e7a (yes, myself). The basic problem here is since the digest state is only saved after the last chunk, the state array is only valid when handling the first chunk of the next buffer. Broken since linux-3.0.

crypto: caam - fix operator precedence in shared descriptor allocation

2011-06-29T23:43:27Z

setkey allocates 16 bytes (CAAM_CMD_SZ * DESC_AEAD_SHARED_TEXT_LEN) shy of what is needed to store the shared descriptor, resulting in memory corruption. Fix this. Signed-off-by: Kim Phillips Signed-off-by: Herbert Xu

[S390] ap: skip device registration on type probe failure

2011-05-23T08:24:29Z

The registration of an ap device will be skipped, if the device type probing fails. Add names of current crypto adapters to the Kconfig help. Signed-off-by: Holger Dengler Signed-off-by: Martin Schwidefsky

crypto: caam - add support for sha512 variants of existing AEAD algorithms

2011-05-19T04:38:00Z

In doing so, sha512 sized keys would not fit with the current descriptor inlining mechanism, so we now calculate whether keys should be referenced instead by pointers in the shared descriptor. also, use symbols for descriptor text lengths, and, ahem, unmap and free key i/o memory in cra_exit.

crypto: caam - fix decryption shared vs. non-shared key setting

2011-05-19T04:37:59Z

Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.
