crypto: skcipher - Remove top-level givcipher interface

2016-07-18T09:35:46+00:00

This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2. As this is the final entry point into givcipher this patch also removes all traces of the top-level givcipher interface, including all implicit IV generators such as chainiv. The bottom-level givcipher interface remains until the drivers using it are converted. Signed-off-by: Herbert Xu

crypto: eseqiv - Offer normal cipher functionality without RNG

2015-06-22T07:49:28+00:00

The RNG may not be available during early boot, e.g., the relevant modules may not be included in the initramfs. As the RNG Is only needed for IPsec, we should not let this prevent use of ciphers without IV generators, e.g., for disk encryption. This patch postpones the RNG allocation to the init function so that one failure during early boot does not make the RNG unavailable for all subsequent users of the same cipher. More importantly, it lets the cipher live even if RNG allocation fails. Of course we no longer offer IV generation and which will fail with an error if invoked. But all other cipher capabilities will function as usual. Signed-off-by: Herbert Xu

crypto: eseqiv - Move IV seeding into init function

2015-06-04T07:05:00+00:00

We currently do the IV seeding on the first givencrypt call in order to conserve entropy. However, this does not work with DRBG which cannot be called from interrupt context. In fact, with DRBG we don't need to conserve entropy anyway. So this patch moves the seeding into the init function. Signed-off-by: Herbert Xu

crypto: include crypto- module prefix in template

2014-11-26T12:06:30+00:00

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

2014-08-01T14:35:55+00:00

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: Use scatterwalk_crypto_chain

2010-12-02T06:47:16+00:00

Use scatterwalk_crypto_chain in favor of locally defined chaining functions. Signed-off-by: Steffen Klassert Signed-off-by: Herbert Xu

crypto: eseqiv - Fix IV generation for sync algorithms

2009-04-15T12:45:03+00:00

If crypto_ablkcipher_encrypt() returns synchronous, eseqiv_complete2() is called even if req->giv is already the pointer to the generated IV. The generated IV is overwritten with some random data in this case. This patch fixes this by calling eseqiv_complete2() just if the generated IV has to be copied to req->giv.

crypto: skcipher - Use RNG interface instead of get_random_bytes

2008-08-29T05:50:06+00:00

This patch makes the IV generators use the new RNG interface so that the user can pick an RNG other than the default get_random_bytes. Signed-off-by: Herbert Xu

crypto: skcipher - Move IV generators into their own modules

2008-08-29T05:50:00+00:00

This patch moves the default IV generators into their own modules in order to break a dependency loop between cryptomgr, rng, and blkcipher. Signed-off-by: Herbert Xu

[CRYPTO] eseqiv: Fix off-by-one encryption

2008-05-01T10:22:28+00:00

After attaching the IV to the head during encryption, eseqiv does not increase the encryption length by that amount. As such the last block of the actual plain text will be left unencrypted. Fortunately the only user of this code hifn currently crashes so this shouldn't affect anyone :) Signed-off-by: Herbert Xu
