This patch introduces infrastructure for allocating req objects on the stack for AEADs. The additions mirror the existing sync skcipher APIs. This can be used in cases where simple sync AEAD operations are being done. So allocating the request on stack avoides possible out-of-memory errors. The struct crypto_sync_aead is a wrapper around crypto_aead and should be used in its place when sync only requests will be done on the stack. Correspondingly, the request should be allocated with SYNC_AEAD_REQUEST_ON_STACK(). Similar to sync_skcipher APIs, the new sync_aead APIs are wrappers around the regular aead APIs to facilitate sync only operations. The following crypto APIs are added: - struct crypto_sync_aead - crypto_alloc_sync_aead() - crypto_free_sync_aead() - crypto_aync_aead_tfm() - crypto_sync_aead_setkey() - crypto_sync_aead_setauthsize() - crypto_sync_aead_authsize() - crypto_sync_aead_maxauthsize() - crypto_sync_aead_ivsize() - crypto_sync_aead_blocksize() - crypto_sync_aead_get_flags() - crypto_sync_aead_set_flags() - crypto_sync_aead_clear_flags() - crypto_sync_aead_reqtfm() - aead_request_set_sync_tfm() - SYNC_AEAD_REQUEST_ON_STACK() Signed-off-by: T Pratham <t-pratham@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
