crypto: user - constify netlink dispatch table

2013-03-10T08:46:43+00:00

There is no need to modify the netlink dispatch table at runtime and
making it const even makes the resulting object file slightly smaller.

crypto: user - ensure user supplied strings are nul-terminated

2013-02-19T12:27:04+00:00

To avoid misuse, ensure cru_name and cru_driver_name are always
nul-terminated strings.

crypto: user - fix empty string test in report API

2013-02-19T12:27:04+00:00

The current test for empty strings fails because it is testing the
address of a field, not a pointer. So the test will always be true.
Test the first character in the string to not be null instead.

crypto: user - fix info leaks in report API

2013-02-19T12:27:03+00:00

Three errors resulting in kernel memory disclosure:

1/ The structures used for the netlink based crypto algorithm report API
are located on the stack. As snprintf() does not fill the remainder of
the buffer with null bytes, those stack bytes will be disclosed to users
of the API. Switch to strncpy() to fix this.

2/ crypto_report_one() does not initialize all field of struct
crypto_user_alg. Fix this to fix the heap info leak.

3/ For the module name we should copy only as many bytes as
module_name() returns -- not as much as the destination buffer could
hold. But the current code does not and therefore copies random data
from behind the end of the module name, as the module name is always
shorter than CRYPTO_MAX_ALG_NAME.

Also switch to use strncpy() to copy the algorithm's name and
driver_name. They are strings, after all.

2012-10-04T16:06:34+00:00

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.

[ Side note: cut-and-paste duplicate help texts make those conflicts
  harder to read than necessary, thanks to git being smart about
  minimizing conflicts and maximizing the common parts... ]

netlink: Rename pid to portid to avoid confusion

2012-09-10T19:30:41+00:00

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.

netlink: hide struct module parameter in netlink_kernel_create

2012-09-08T22:46:30+00:00

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).

Suggested by David S. Miller.

netlink: add netlink_kernel_cfg parameter to netlink_kernel_create

2012-06-29T23:46:02+00:00

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.
