[Qemu-block] [PATCH 00/25] nbd: Several fixes


From: Max Reitz
Subject: [Qemu-block] [PATCH 00/25] nbd: Several fixes
Date: Wed, 25 Feb 2015 13:08:13 -0500

This series contains a variety of fixes for qemu's NBD code, with the
most interesting (and probably most prone to be wrong) thing being a
timeout of ten seconds for NBD connections.


Max Reitz (25):
  util/uri: Add overflow check to rfc3986_parse_port
  qemu-nbd: Detect unused partitions by system == 0
  nbd: Fix nbd_establish_connection()'s return value
  nbd: Fix response to invalid requests
  nbd: Avoid generic -EINVAL
  nbd: Pass return value from nbd_handle_list()
  nbd: Add "failed to open export" error message
  nbd: Handle blk_getlength() failure
  qemu-nbd: fork() can fail
  nbd: Fix potential signed overflow issues
  qemu-nbd: Fix and improve input verification
  nbd: Set block size to BDRV_SECTOR_SIZE
  nbd: Enforce sector alignment
  coroutine: Add co_yield_timeout()
  coroutine-io: Return -errno in case of error
  coroutine-io: Add I/O functions with timeout
  nbd: Employ timeouts
  nbd: Fix nbd_receive_options()
  nbd: Fix interpretation of the export flags
  block/nbd: Comment on discard/flush silently failing
  nbd: Drop unexpected data for NBD_OPT_LIST
  iotests: Add _timeout function
  iotests: Add test for invalid qemu-nbd parameters
  iotests: Add test for issuing discard over NBD
  iotests: Add test for a non-existing NBD export
