Error propagation is already there for socket backends. Add it to other protocols, simplifying code that tests for errors that will never happen. With all protocols understanding Error, the code can be simplified further by removing the return value. Unfortunately, the quality of error messages varies depending on where the error is detected, because no Error is passed to the NonBlockingConnectHandler. Thus, the exact error message still cannot be sent to the user if the OS reports it asynchronously via SO_ERROR. If NonBlockingConnectHandler received an Error**, we could for example report the error class and/or message via a new field of the query-migration command even if it is reported asynchronously. Before: (qemu) migrate fd:ffff migrate: An undefined error has occurred (qemu) info migrate (qemu) After: (qemu) migrate fd:ffff migrate: File descriptor named 'ffff' has not been found (qemu) info migrate capabilities: xbzrle: off Migration status: failed total time: 0 milliseconds Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

The migration code is using errp to detect "internal" errors, this means that it relies on errp being non-NULL. No impact so far because our only QMP clients (the QMP marshaller and HMP) never pass a NULL Error **. But if we had others, this patch would make sure that migration can work with a NULL Error **.

getaddrinfo can give us a list of addresses, but we only try to connect to the first one. If that fails we never proceed to the next one. This is common on desktop setups that often have ipv6 configured but not actually working. To fix this make inet_connect_nonblocking retry connection with a different address. callers on inet_nonblocking_connect register a callback function that will be called when connect opertion completes, in case of failure the fd will have a negative value Signed-off-by: NOrit Wasserman <owasserm@redhat.com> Signed-off-by: NMichael S.

Use the in_progress argument for QERR_SOCKET_CONNECT_IN_PROGRESS. The other errors are handled the same by checking if the error is set and then calling migrate_fd_error() if it's. It's also necessary to change inet_connect_opts() not to set QERR_SOCKET_CONNECT_IN_PROGRESS. This error is only used by tcp_start_outgoing_migration() and not changing it along with the usage of in_progress would break migration. Furthermore this commit fixes a bug. Today, there's a spurious error report when migration succeeds: (qemu) migrate tcp:0:4444 migrate: Connection can not be completed immediately (qemu) After this commit no spurious error is reported anymore.

It's used to indicate the special case where a valid file-descriptor is returned (ie. success) but the connection can't be completed w/o blocking. This is needed because QERR_SOCKET_CONNECT_IN_PROGRESS is not treated like an error and a future commit will drop it.

Use help functions in qemu-socket.c for tcp migration, which already support ipv6 addresses. Currently errp will be set to UNDEFINED_ERROR when migration fails, qemu would output "migration failed: ...", and current user can see a message("An undefined error has occurred") in monitor. This patch changed tcp_start_outgoing_migration()/inet_connect() /inet_connect_opts(), socket error would be passed back, then current user can see a meaningful err message in monitor. Qemu will exit if listening fails, so output socket error to qemu stderr. For IPv6 brackets must be mandatory if you require a port. Referencing to RFC5952, the recommended format is: [2312::8274]:5200 test status: Successed listen side: qemu-kvm .... -incoming tcp:[2312::8274]:5200 client side: qemu-kvm ...
