crypto: remove redundant type flags from tfm allocation

2018-07-08T16:30:29+00:00

Some crypto API users allocating a tfm with crypto_alloc_$FOO() are also
specifying the type flags for $FOO, e.g. crypto_alloc_shash() with
CRYPTO_ALG_TYPE_SHASH.  But, that's redundant since the crypto API will
override any specified type flag/mask with the correct ones.

So, remove the unneeded flags.

This patch shouldn't change any actual behavior.

docs: */index.rst: Add newer documents to their respective index.rst

2018-05-08T15:57:35+00:00

A number of new docs were added, but they're currently not on
the index.rst from the session they're supposed to be, causing
Sphinx warnings.

Add them.

crypto: doc - clarify hash callbacks state machine

2018-03-30T17:33:02+00:00

Add a note that it is perfectly legal to "abandon" a request object:
- call .init() and then (as many times) .update()
- _not_ call any of .final(), .finup() or .export() at any point in
  future

crypto: doc - adapt api sample to use async. op wait

2017-11-03T14:11:23+00:00

The code sample is waiting for an async. crypto op completion.
Adapt sample to use the new generic infrastructure to do the same.

This also fixes a possible data coruption bug created by the
use of wait_for_completion_interruptible() without dealing
correctly with an interrupt aborting the wait prior to the
async op finishing.

crypto: doc - Fixed bugs, added example usage of calc_hash().

2017-06-19T06:11:56+00:00

- Fixed bugs in example for shash and rng (added missing "*" and " *").
- Corrected pr_info() in calc_hash().
- Added example usage of calc_hash().
- No need for negate PTR_ERR to get error code, as crypto_alloc_rng
  already returns negative values like ERR_PTR(-ENOMEM). Fixed.
