crypto: picoxcell - Forbid 2-key 3DES in FIPS mode

2019-04-18T14:15:00+00:00

This patch forbids the use of 2-key 3DES (K1 == K3) in FIPS mode. It also removes an unnecessary key length checks that are already performed by the crypto API. Signed-off-by: Herbert Xu

crypto: clarify name of WEAK_KEY request flag

2019-01-25T10:41:52+00:00

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: skcipher - remove remnants of internal IV generators

2018-12-23T03:52:45+00:00

Remove dead code related to internal IV generators, which are no longer used since they've been replaced with the "seqiv" and "echainiv" templates. The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "" or "" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: picoxcell - Remove VLA usage of skcipher

2018-09-28T04:46:09+00:00

In the quest to remove all stack VLA usage from the kernel[1], this replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(), which uses a fixed stack size.

crypto: drivers - simplify getting .drvdata

2018-04-28T08:09:35+00:00

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Reviewed-by: Krzysztof Kozlowski Signed-off-by: Herbert Xu

crypto: picoxcell - don't leak pointers to authenc keys

2018-03-30T17:33:13+00:00

In spacc_aead_setkey we save pointers to the authenc keys in a local variable of type struct crypto_authenc_keys and we don't zeroize it after use. Fix this and don't leak pointers to the authenc keys. Signed-off-by: Tudor Ambarus Reviewed-by: Jamie Iles Signed-off-by: Herbert Xu

crypto: picoxcell - Fix error handling in spacc_probe()

2018-01-25T14:10:36+00:00

If clk_get() fails, device_remove_file() looks inappropriate. The error path, where all crypto_register fail, misses resource deallocations. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Reviewed-by: Jamie Iles Signed-off-by: Herbert Xu

crypto: Convert timers to use timer_setup()

2017-11-06T20:49:44+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
