crypto: cryptd - initialize child shash_desc on import

2016-10-02T23:12:33Z

[ Upstream commit 0bd2223594a4dcddc1e34b15774a3a4776f7749e ] When calling .import() on a cryptd ahash_request, the structure members that describe the child transform in the shash_desc need to be initialized like they are when calling .init() Cc: stable@vger.kernel.org Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: cryptd - process CRYPTO_ALG_INTERNAL

2015-03-31T13:21:04Z

The cryptd is used as a wrapper around internal ciphers. Therefore, the cryptd must process the internal cipher by marking cryptd as internal if the underlying cipher is an internal cipher. Signed-off-by: Stephan Mueller Signed-off-by: Herbert Xu

crypto: include crypto- module prefix in template

2014-11-26T12:06:30Z

This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause Signed-off-by: Kees Cook Acked-by: Mathias Krause Signed-off-by: Herbert Xu

crypto: Resolve shadow warnings

2014-08-01T14:35:55Z

Change formal parameters to not clash with global names to eliminate many W=2 warnings. Signed-off-by: Mark Rustad Signed-off-by: Jeff Kirsher Signed-off-by: Herbert Xu

crypto: cryptd - disable softirqs in cryptd_queue_worker to prevent data corruption

2012-10-24T13:21:18Z

cryptd_queue_worker attempts to prevent simultaneous accesses to crypto workqueue by cryptd_enqueue_request using preempt_disable/preempt_enable. However cryptd_enqueue_request might be called from softirq context, so add local_bh_disable/local_bh_enable to prevent data corruption and panics. Bug report at http://marc.info/?l=linux-crypto-vger&m=134858649616319&w=2 v2: - Disable software interrupts instead of hardware interrupts Cc: stable@vger.kernel.org Reported-by: Gurucharan Shetty Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: cryptd - Use subsys_initcall to prevent races with aesni

2011-08-20T08:08:03Z

As cryptd is depeneded on by other algorithms such as aesni-intel, it needs to be registered before them. When everything is built as modules, this occurs naturally. However, for this to work when they are built-in, we need to use subsys_initcall in cryptd. Tested-by: Josh Boyer Signed-off-by: Herbert Xu

crypto: cryptd - Adding the AEAD interface type support to cryptd

2010-09-20T08:05:12Z

This patch adds AEAD support into the cryptd framework. Having AEAD support in cryptd enables crypto drivers that use the AEAD interface type (such as the patch for AEAD based RFC4106 AES-GCM implementation using Intel New Instructions) to leverage cryptd for asynchronous processing.

percpu: add __percpu sparse annotations to what's left

2010-02-17T02:17:38Z

Add __percpu sparse annotations to places which didn't make it in one of the previous patches. All converions are trivial. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds.

crypto: ghash - Add PCLMULQDQ accelerated implementation

2009-10-19T02:53:06Z

PCLMULQDQ is used to accelerate the most time-consuming part of GHASH, carry-less multiplication. More information about PCLMULQDQ can be found at: http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/ Because PCLMULQDQ changes XMM state, its usage must be enclosed with kernel_fpu_begin/end, which can be used only in process context, the acceleration is implemented as crypto_ahash. That is, request in soft IRQ context will be defered to the cryptd kernel thread. Signed-off-by: Huang Ying Signed-off-by: Herbert Xu
