      crypto: powerpc - move files to fix build error · 3265c4ba
      Kim Phillips authored
      The current cryptodev-2.6 tree commits:
      
      d9850fc5 ("crypto: powerpc/sha1 - kernel config")
      50ba29aa ("crypto: powerpc/sha1 - glue")
      
      failed to properly place files under arch/powerpc/crypto, which
      leads to build errors:
      
      make[1]: *** No rule to make target 'arch/powerpc/crypto/sha1-spe-asm.o', needed by 'arch/powerpc/crypto/sha1-ppc-spe.o'.  Stop.
      make[1]: *** No rule to make target 'arch/powerpc/crypto/sha1_spe_glue.o', needed by 'arch/powerpc/crypto/sha1-ppc-spe.o'.  Stop.
      Makefile:947: recipe for target 'arch/powerpc/crypto' failed
      
      Move the two sha1 spe files under crypto/, and whilst there, rename
      other powerpc crypto files with underscores to use dashes for
      consistency.

      crypto: doc - AEAD / RNG AF_ALG interface · dbe5fe7e
      Stephan Mueller authored
      The patch moves the information provided in
      Documentation/crypto/crypto-API-userspace.txt into a separate chapter in
      the kernel crypto API DocBook. Some corrections are applied (such as
      removing a reference to Netlink when the AF_ALG socket is referred to).
      
      In addition, the AEAD and RNG interface description is now added.
      
      Also, a brief description of the zero-copy interface with an example
      code snippet is provided.

      crypto: rng - RNGs must return 0 in success case · cde001e4
      Stephan Mueller authored
      Change the RNGs to always return 0 in success case.
      
      This patch ensures that seqiv.c works with RNGs other than krng. seqiv
      expects that any return code other than 0 is an error. Without the
      patch, rfc4106(gcm(aes)) will not work when using a DRBG or an ANSI
      X9.31 RNG.

      hwrng: caam - fix rng_unmap_ctx's DMA_UNMAP size problem · 4842234f
      Yanjiang Jin authored
      Fix rng_unmap_ctx's DMA_UNMAP size problem for caam_rng, else system would
      report the below calltrace during cleanup caam_rng.
      Since rng_create_sh_desc() creates a fixed descriptor of exactly 4
      command-lengths now, also update DESC_RNG_LEN to (4 * CAAM_CMD_SZ).
