^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   7) Introduction
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   8) ============
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   9) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  10) The Scatterlist Crypto API takes page vectors (scatterlists) as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  11) arguments, and works directly on pages.  In some cases (e.g. ECB
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  12) mode ciphers), this will allow for pages to be encrypted in-place
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  13) with no copying.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  15) One of the initial goals of this design was to readily support IPsec,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  16) so that processing can be applied to paged skb's without the need
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  17) for linearization.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  20) Details
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  21) =======
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  22) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  23) At the lowest level are algorithms, which register dynamically with the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  24) API.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  25) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  26) 'Transforms' are user-instantiated objects, which maintain state, handle all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  27) of the implementation logic (e.g. manipulating page vectors) and provide an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  28) abstraction to the underlying algorithms.  However, at the user
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  29) level they are very simple.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  31) Conceptually, the API layering looks like this::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  32) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  33)   [transform api]  (user interface)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  34)   [transform ops]  (per-type logic glue e.g. cipher.c, compress.c)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  35)   [algorithm api]  (for registering algorithms)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  36) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  37) The idea is to make the user interface and algorithm registration API
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  38) very simple, while hiding the core logic from both.  Many good ideas
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  39) from existing APIs such as Cryptoapi and Nettle have been adapted for this.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  40) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  41) The API currently supports five main types of transforms: AEAD (Authenticated
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  42) Encryption with Associated Data), Block Ciphers, Ciphers, Compressors and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  43) Hashes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  44) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  45) Please note that Block Ciphers is somewhat of a misnomer.  It is in fact
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  46) meant to support all ciphers including stream ciphers.  The difference
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  47) between Block Ciphers and Ciphers is that the latter operates on exactly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  48) one block while the former can operate on an arbitrary amount of data,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  49) subject to block size requirements (i.e., non-stream ciphers can only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  50) process multiples of blocks).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  51) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  52) Here's an example of how to use the API::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  53)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  87) ===============
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  88) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  89) Transforms may only be allocated in user context, and cryptographic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  90) methods may only be called from softirq and user contexts.  For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  91) transforms with a setkey method it too should only be called from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  92) user context.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  93) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  94) When using the API for ciphers, performance will be optimal if each
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  95) scatterlist contains data which is a multiple of the cipher's block
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  96) size (typically 8 bytes).  This prevents having to do any copying
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  97) across non-aligned page fragment boundaries.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100) Adding New Algorithms
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) =====================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) When submitting a new algorithm for inclusion, a mandatory requirement
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) is that at least a few test vectors from known sources (preferably
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) standards) be included.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107) Converting existing well known code is preferred, as it is more likely
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108) to have been reviewed and widely tested.  If submitting code from LGPL
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) sources, please consider changing the license to GPL (see section 3 of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) the LGPL).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112) Algorithms submitted must also be generally patent-free (e.g. IDEA
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) will not be included in the mainline until around 2011), and be based
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 114) on a recognized standard and/or have been subjected to appropriate
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 115) peer review.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 116) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 117) Also check for any RFCs which may relate to the use of specific algorithms,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 118) as well as general application notes such as RFC2451 ("The ESP CBC-Mode

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 120) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 121) It's a good idea to avoid using lots of macros and use inlined functions
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 122) instead, as gcc does a good job with inlining, while excessive use of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 123) macros can cause compilation problems on some platforms.
