      crypto: algif_skcipher - Handle unaligned receive buffer · bc97e57e
      Herbert Xu authored
      As it is if user-space passes through a receive buffer that's not
      aligned to to the cipher block size, we'll end up encrypting or
      decrypting a partial block which causes a spurious EINVAL to be
      returned.
      
      This patch fixes this by moving the partial block test after the
      af_alg_make_sg call.

      crypto: algif_skcipher - Fixed overflow when sndbuf is page aligned · 0f6bb83c
      Herbert Xu authored
      When sk_sndbuf is not a multiple of PAGE_SIZE, the limit tests
      in sendmsg fail as the limit variable becomes negative and we're
      using an unsigned comparison.
      
      The same thing can happen if sk_sndbuf is lowered after a sendmsg
      call.
      
      This patch fixes this by always taking the signed maximum of limit
      and 0 before we perform the comparison.
      
      It also rounds the value of sk_sndbuf down to a multiple of PAGE_SIZE
      so that we don't end up allocating a page only to use a small number
      of bytes in it because we're bound by sk_sndbuf.

      crypto: algif_skcipher - User-space interface for skcipher operations · 8ff59090
      Herbert Xu authored
      This patch adds the af_alg plugin for symmetric key ciphers,
      corresponding to the ablkcipher kernel operation type.
      
      Keys can optionally be set through the setsockopt interface.
      
      Once a sendmsg call occurs without MSG_MORE no further writes
      may be made to the socket until all previous data has been read.
      
      IVs and and whether encryption/decryption is performed can be
      set through the setsockopt interface or as a control message
      to sendmsg.
      
      The interface is completely synchronous, all operations are
      carried out in recvmsg(2) and will complete prior to the system
      call returning.
      
      The splice(2) interface support reading the user-space data directly
      without copying (except that the Crypto API itself may copy the data
      if alignment is off).
      
      The recvmsg(2) interface supports directly writing to user-space
      without additional copying, i.e., the kernel crypto interface will
      receive the user-space address as its output SG list.
      
      Thakns to Miloslav Trmac for reviewing this and contributing
      fixes and improvements.

      crypto: algif_hash - User-space interface for hash operations · fe869cdb
      Herbert Xu authored
      This patch adds the af_alg plugin for hash, corresponding to
      the ahash kernel operation type.
      
      Keys can optionally be set through the setsockopt interface.
      
      Each sendmsg call will finalise the hash unless sent with a MSG_MORE
      flag.
      
      Partial hash states can be cloned using accept(2).
      
      The interface is completely synchronous, all operations will
      complete prior to the system call returning.
      
      Both sendmsg(2) and splice(2) support reading the user-space
      data directly without copying (except that the Crypto API itself
      may copy the data if alignment is off).
      
      For now only the splice(2) interface supports performing digest
      instead of init/update/final.  In future the sendmsg(2) interface
      will also be modified to use digest/finup where possible so that
      hardware that cannot return a partial hash state can still benefit
      from this interface.

      crypto: af_alg - User-space interface for Crypto API · 03c8efc1
      Herbert Xu authored
      This patch creates the backbone of the user-space interface for
      the Crypto API, through a new socket family AF_ALG.
      
      Each session corresponds to one or more connections obtained from
      that socket.  The number depends on the number of inputs/outputs
      of that particular type of operation.  For most types there will
      be a s ingle connection/file descriptor that is used for both input
      and output.  AEAD is one of the few that require two inputs.
      
      Each algorithm type will provide its own implementation that plugs
      into af_alg.  They're keyed using a string such as "skcipher" or
      "hash".
      
      IOW this patch only contains the boring bits that is required
      to hold everything together.

      Unfortunately perf can't deal with anything other than direct structure
      accesses in the TP_printk() section.  It will drop dead when it sees
      jbd2_dev_to_name() in the "print fmt" section of the tracepoint.
