• d3f7d56a7   net: update consumers of MSG_MORE to recognize MSG_SENDPAGE_NOTLAST ... Browse Code »

  6

  Commit 35f9c09fe (tcp: tcp_sendpages() should call tcp_push() once)
  added an internal flag MSG_SENDPAGE_NOTLAST, similar to
  MSG_MORE.

  algif_hash, algif_skcipher, and udp used MSG_MORE from tcp_sendpages()
  and need to see the new flag as identical to MSG_MORE.

  This fixes sendfile() on AF_ALG.

  v3: also fix udp

  This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
  set msg_namelen to the proper size

• 72a763d80   crypto: algif - suppress sending source address information in recvmsg ... Browse Code »

  The current code does not set the msg_namelen member to 0 and therefore
  makes net/socket.c leak the local sockaddr_storage variable to userland
  -- 128 bytes of kernel stack memory. Fix that.

• 269230e7c   crypto: algif_hash - Handle initial af_alg_make_sg error correctly ... Browse Code »

  When the first call to af_alg_make_sg fails, we may return garbage
  instead of the real error. This patch fixes it by setting the error
  if "copied" is zero.

  Based on a patch by Jesper Juhl.

• fe869cdb8   crypto: algif_hash - User-space interface for hash operations ... Browse Code »

  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.

  Thakns to Miloslav Trmac for reviewing this and contributing
  fixes and improvements.
