This patchset adds a netlink based user configuration API for the crypto layer, similar to the configuration API of xfrm. The patchset is based on the current cryptodev tree. A userspace tool that makes use of the configuration API is available at https://sourceforge.net/projects/crconf/files/crconf-pre2.tar.gz With this it is possible to instantiate certain algorithms by doing crconf add driver "cbc(aes-generic)" type 4 or crconf add driver "cbc(aes-generic)" type 4 priority 100 To remove a (form templates build and unused) algorithm with all subsequent algorithms do crconf del driver "cbc(aes-generic)" type 4 It is possible to update the priority of an algorithm by doing crconf update driver "cbc(aes-generic)" type 4 priority 200 this updates the priority of this algorithm and removes all algorithms on top. Finally it is possible to print the instantiated crypto algorithms similar to /proc/crypto by doing crconf show all This prints the algorithm informations of all instantiated algorithms as long as the information fits into a netlink message. Changes from v1: - Removed the priority update functions. - Fix algorithm information printing when build as module. - Update the crconf tool according to the kernel changes. Changes from v2: - Use one structure for creating and basic querying of algorithms. - Send the algorithm flags to userspace, so the userspace can check for things like passed selftest, async algorithms etc. - Update the crconf tool according to the kernel changes. - Add some priority update functions. We need to be able to update the priority of algorithms, as we can't delete core algorithms like aes-generic. When we update the priority of an algorithm, we remove all algorithms on top. Changes from v3: - Remove the priority field from struct crypto_user_alg and use the existing netlink attribute to send the priority value to userspace. - Update the crconf tool according to the kernel changes. - Don't distinguish between netlink attributes that use the same type value.
