2017-08-01char: don't exit on hmp 'chardev-add help'Anton Nefedov
qemu_chr_new_from_opts() is used from both vl.c and hmp, and it is quite confusing to see qemu suddenly exit after receiving a help option in hmp. Do exit(0) from vl.c instead.

2017-07-14char: chardevice hotswapAnton Nefedov
This patch adds a possibility to change a char device without a frontend removal. Ideally, it would have to happen transparently to a frontend, i.e. frontend would continue its regular operation. However, backends are not stateless and are set up by the frontends via qemu_chr_fe_<> functions, and it's not (generally) possible to replay that setup entirely in a backend code, as different chardevs respond to the setup calls differently, so do frontends work differently basing on those setup responses. Moreover, some frontend can generally get and save the backend pointer (qemu_chr_fe_get_driver()), and it will become invalid after backend change. So, a frontend which would like to support chardev hotswap has to register a "backend change" handler, and redo its backend setup there.

2017-05-03char: Fix removing wrong GSource that be found by fd_in_tagzhanghailiang
We use fd_in_tag to find a GSource, fd_in_tag is return value of g_source_attach(GSource *source, GMainContext *context), the return value is unique only in the same context, so we may get the same values with different 'context' parameters. It is no problem to find the right fd_in_tag by using g_main_context_find_source_by_id(GMainContext *context, guint source_id) while there is only one default main context. But colo-compare tries to create/use its own context, and if we pass wrong 'context' parameter with right fd_in_tag, we will find a wrong GSource to handle. We tried to fix the related codes in commit b43decb015a6efeb9e3cdbdb80f6547ad7248a4c, but it didn't fix the bug completely, because we still have some codes didn't pass *right* context parameter for remove_fd_in_watch(). Let's fix it by record the GSource directly instead of fd_in_tag.

Fix that. Pick the output format to match socket_parse(), just like the existing formats.

2017-04-03nbd sockets vnc: Mark problematic address family tests TODOMarkus Armbruster
Certain features make sense only with certain address families. For instance, passing file descriptors requires AF_UNIX. Testing SocketAddress's saddr->type == SOCKET_ADDRESS_KIND_UNIX is obvious, but problematic: it can't recognize AF_UNIX when type == SOCKET_ADDRESS_KIND_FD. Mark such tests of saddr->type TODO. We may want to check the address family with getsockname() there. Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Daniel P.

2017-03-06char: remove the right fd been watched in qemu_chr_fe_set_handlers()zhanghailiang
We can call qemu_chr_fe_set_handlers() to add/remove fd been watched in 'context' which can be either default main context or other explicit context. But the original logic is not correct, we didn't remove the right fd because we call g_main_context_find_source_by_id(NULL, tag) which always try to find the Gsource from default context. Fix it by passing the right context to g_main_context_find_source_by_id().
