2019-05-21treewide: Add SPDX license identifier for more missed filesThomas Gleixner1-0/+1
Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2018-01-12crypto: hash - annotate algorithms taking optional keyEric Biggers1-0/+1
We need to consistently enforce that keyed hashes cannot be used without setting the key. To do this we need a reliable way to determine whether a given hash algorithm is keyed or not. AF_ALG currently does this by checking for the presence of a ->setkey() method. However, this is actually slightly broken because the CRC-32 algorithms implement ->setkey() but can also be used without a key. (The CRC-32 "key" is not actually a cryptographic key but rather represents the initial state. If not overridden, then a default initial state is used.) Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which indicates that the algorithm has a ->setkey() method, but it is not required to be called. Then set it on all the CRC-32 algorithms. The same also applies to the Adler-32 implementation in Lustre. Also, the cryptd and mcryptd templates have to pass through the flag from their underlying algorithm.

2014-11-24crypto: prefix module autoloading with "crypto-"Kees Cook1-1/+1
This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2012-11-09sparc64: Fix build with mix of modular vs. non-modular crypto drivers.David S. Miller1-0/+2
We tried linking in a single built object to hold the device table, but only works if all of the sparc64 crypto modules get built the same way (modular vs. non-modular). Just include the device ID stub into each driver source file so that the table gets compiled into the correct result in all cases. Reported-by: Meelis Roos <[email protected]> Signed-off-by: David S.

2012-09-15sparc64: Adjust crypto priorities.David S. Miller1-1/+3
Make the crypto opcode implementations have a higher priority than those provides by the ring buffer based Niagara crypto device. Also, several crypto opcode hashes were not setting the priority value at all. Signed-off-by: David S. Miller <[email protected]>
