      crypto: cavium/nitrox - remove check of list iterator against head past the loop body · 7b2206d8
      Jakob Koschel authored
      When list_for_each_entry() completes the iteration over the whole list
      without breaking the loop, the iterator value will be a bogus pointer
      computed based on the head element.
      
      While it is safe to use the pointer to determine if it was computed
      based on the head element, either with list_entry_is_head() or
      &pos->member == head, using the iterator variable after the loop should
      be avoided.
      
      In preparation to limit the scope of a list iterator to the list
      traversal loop, use a dedicated pointer to point to the found element [1].

      crypto: ccp - When TSME and SME both detected notify user · 4e2c8794
      Mario Limonciello authored
      CC_ATTR_HOST_MEM_ENCRYPT is used to relay that memory encryption has been
      activated by the kernel.
      
      As it's technically possible to enable both SME and TSME at the same time,
      detect this scenario and notify the user that enabling TSME and SME at the
      same time is unnecessary.

      crypto: ccp - Allow PSP driver to load without SEV/TEE support · 84ee393b
      Mario Limonciello authored
      Previously the PSP probe routine would fail if both SEV and TEE were
      missing.  This is possibly the case for some client parts.
      
      As capabilities can now be accessed from userspace, it may still be
      useful to have the PSP driver finish loading so that those capabilities
      can be read.

      crypto: testmgr - test in-place en/decryption with two sglists · f17f9e90
      Eric Biggers authored
      As was established in the thread
      https://lore.kernel.org/linux-crypto/20220223080400.139367-1-gilad@benyossef.com/T/#u,
      many crypto API users doing in-place en/decryption don't use the same
      scatterlist pointers for the source and destination, but rather use
      separate scatterlists that point to the same memory.  This case isn't
      tested by the self-tests, resulting in bugs.
      
      This is the natural usage of the crypto API in some cases, so requiring
      API users to avoid this usage is not reasonable.
      
      Therefore, update the self-tests to start testing this case.

      crypto: x86 - eliminate anonymous module_init & module_exit · f16a005c
      Randy Dunlap authored
      Eliminate anonymous module_init() and module_exit(), which can lead to
      confusion or ambiguity when reading System.map, crashes/oops/bugs,
      or an initcall_debug log.
      
      Give each of these init and exit functions unique driver-specific
      names to eliminate the anonymous names.
      
      Example 1: (System.map)
       ffffffff832fc78c t init
       ffffffff832fc79e t init
       ffffffff832fc8f8 t init
      
      Example 2: (initcall_debug log)
       calling  init+0x0/0x12 @ 1
       initcall init+0x0/0x12 returned 0 after 15 usecs
       calling  init+0x0/0x60 @ 1
       initcall init+0x0/0x60 returned 0 after 2 usecs
       calling  init+0x0/0x9a @ 1
       initcall init+0x0/0x9a returned 0 after 74 usecs

      This adds ARMv8 NEON implementations of SM4 in ECB, CBC, CFB and CTR
      modes. This implementation uses the plain NEON instruction set, All
      S-BOX substitutions uses the tbl/tbx instructions of ARMv8, combined
      with the out-of-order execution in CPU, this optimization supports
      encryption of up to 8 blocks at the same time.
      
      The performance of encrypting one block is not as good as software
      implementation, so the encryption operations of CBC and CFB still

      crypto: arm64/sm4-ce - rename to sm4-ce-cipher · 02436762
      Tianjia Zhang authored
      The subsequent patches of the series will have an implementation
      of SM4-ECB/CBC/CFB/CTR accelerated by the CE instruction set, which
      conflicts with the current module name. In order to keep the naming
      rules of the AES algorithm consistent, the sm4-ce algorithm is
      renamed to sm4-ce-cipher.
      
      In addition, the speed of sm4-ce-cipher is better than that of SM4
      NEON. By the way, the priority of the algorithm is adjusted to 300,
      which is also to leave room for the priority of SM4 NEON.

      crypto: sm3,sm4 - move into crypto directory · d2825fa9
      Jason A. Donenfeld authored
      The lib/crypto libraries live in lib because they are used by various
      drivers of the kernel. In contrast, the various helper functions in
      crypto are there because they're used exclusively by the crypto API. The
      SM3 and SM4 helper functions were erroniously moved into lib/crypto/
      instead of crypto/, even though there are no in-kernel users outside of
      the crypto API of those functions. This commit moves them into crypto/.

      This log message was accidentally chopped off.
      
      I was wondering why this happened, but checking the ML log, Mark
      precisely followed my suggestion [1].
      
      I just used "..." because I was too lazy to type the sentence fully.
      Sorry for the confusion.
