[Qemu-devel] [PATCH v7 0/5] support to migrate with IPv6 address

[Amos Kong]

Those patches make tcp migration use the help functions in
qemu-socket.c for support IPv6 migration.

Changes from v1:
- split different changes to small patches, it will be easier to review
- fixed some problem according to Kevin's comment

Changes from v2:
- fix issue of returning real error 
- set s->fd to -1 when parse fails, won't call migrate_fd_error()

Changes from v3:
- try to use help functions in qemu-socket.c

Changes from v4:
- introduce set_socket_error() to restore real errno
- fix connect error process

Changes from v5:
- use error class to pass socket error

Changes from v6:
- merge error process and nonblock support together
- fix leak of repeatedly error_set()
- coding style fix
- fix EWOULDBLOCK process

I just updated the patchset according michael and orit's
comments. Current patch handles EWOULDBLOCK same as
migration-tcp.c. The introduced qerror strings are
basically sufficient, we can fix migration error handle
later. Thanks for your time!

Amos Kong (4):
      qerror: add five qerror strings
      sockets: change inet_connect() to support nonblock socket
      sockets: use error class to pass listen error
      use inet_listen()/inet_connect() to support ipv6 migration
