crypto: LLVMLinux: aligned-attribute.patch

2014-06-07T18:44:39+00:00

__attribute__((aligned)) applies the default alignment for the largest scalar
type for the target ABI. gcc allows it to be applied inline to a defined type.
Clang only allows it to be applied to a type definition (PR11071).

Making it into 2 lines makes it more readable and works with both compilers.

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.

crypto: add crypto_[un]register_shashes for [un]registering multiple shash entries at once

2012-08-01T09:47:26+00:00

Add crypto_[un]register_shashes() to allow simplifying init/exit code of shash
crypto modules that register multiple algorithms.

crypto: Stop using NLA_PUT*().

2012-04-02T08:33:42+00:00

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

crypto: algapi - Fix build problem with NET disabled

2011-11-10T22:57:06+00:00

The report functions use NLA_PUT so we need to ensure that NET
is enabled.

crypto: hash - Fix async import on shash algorithm

2010-11-04T18:48:37+00:00

The function shash_async_import did not initialise the descriptor
correctly prior to calling the underlying shash import function.

This patch adds the required initialisation.

crypto: shash - Remove usage of CRYPTO_MINALIGN

2010-05-19T01:50:58+00:00

The macro CRYPTO_MINALIGN is not meant to be used directly.  This
patch replaces it with crypto_tfm_ctx_alignment.
