      crypto: tcrypt - Add debug prints · 76512f2d
      Rabin Vincent authored
      tcrypt is very tight-lipped when it succeeds, but a bit more feedback
      would be useful when developing or debugging crypto drivers, especially
      since even a successful run ends with the module failing to insert. Add
      a couple of debug prints, which can be enabled with dynamic debug:
      
      Before:
      
       # insmod tcrypt.ko mode=10
       insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable
      
      After:
      
       # insmod tcrypt.ko mode=10 dyndbg
       tcrypt: testing ecb(aes)
       tcrypt: testing cbc(aes)
       tcrypt: testing lrw(aes)
       tcrypt: testing xts(aes)
       tcrypt: testing ctr(aes)
       tcrypt: testing rfc3686(ctr(aes))
       tcrypt: all tests passed
       insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable

      crypto: tcrypt - Use ahash · 0660511c
      Herbert Xu authored
      This patch removes the last user of the obsolete crypto_hash
      interface, tcrypt, by simply switching it over to ahash.  In
      fact it already has all the code there so it's just a matter
      of calling the ahash speed test code with the right mask.

      crypto: tcrypt - avoid mapping from module image addresses · f074f7b1
      Horia Geant? authored
      The output buffer in test_ahash_speed will point to an address located
      within the tcrypt module image.
      This causes problems when trying to DMA map the buffer.
      For e.g. on ARM-based LS1021A, a page fault occurs within the
      DMA API when trying to access the struct page returned by
      virt_to_page(output):
      
      insmod tcrypt.ko mode=403
      
      testing speed of async sha1 (sha1-caam)
      test  0 (   16 byte blocks,   16 bytes per update,   1 updates):
      Unable to handle kernel paging request at virtual address f07e9080
      pgd = e58d0e00
