Pull crypto update from Herbert Xu: - Optimised AES/SHA1 for ARM. - IPsec ESN support in talitos and caam. - x86_64/avx implementation of cast5/cast6. - Add/use multi-algorithm registration helpers where possible. - Added IBM Power7+ in-Nest support. - Misc fixes. Fix up trivial conflicts in crypto/Kconfig due to the sparc64 crypto config options being added next to the new ARM ones.

2012-09-10netlink: Rename pid to portid to avoid confusionEric W. Biederman1-2/+2
It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.

2012-09-08netlink: hide struct module parameter in netlink_kernel_createPablo Neira Ayuso1-2/+1
This patch defines netlink_kernel_create as a wrapper function of __netlink_kernel_create to hide the struct module *me parameter (which seems to be THIS_MODULE in all existing netlink subsystems).

2012-06-29netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso1-2/+5
This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-03-29crypto: user - Fix size of netlink dump messageSteffen Klassert1-0/+8
The default netlink message size limit might be exceeded when dumping a lot of algorithms to userspace. As a result, not all of the instantiated algorithms dumped to userspace. So calculate an upper bound on the message size and call netlink_dump_start() with that value.

2012-03-29crypto: user - Fix lookup of algorithms with IV generatorSteffen Klassert1-1/+71
We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg().

2012-02-05crypto: In crypto_add_alg(), 'exact' wants to be initialized to 0Jesper Juhl1-1/+1
We declare 'exact' without initializing it and then do: [...] if (strlen(p->cru_driver_name)) exact = 1; if (priority && !exact) return -EINVAL; [...] If the first 'if' is not true, then the second will test an uninitialized 'exact'. As far as I can tell, what we want is for 'exact' to be initialized to 0 (zero/false).

2011-11-09crypto: Unlink and free instances when deletedSteffen Klassert1-1/+1
We leak the crypto instance when we unregister an instance with crypto_del_alg(). Therefore we introduce crypto_unregister_instance() to unlink the crypto instance from the template's instances list and to free the recources of the instance properly.
