* char: don't skip client cleanup if 'connected' flag is unsetDaniel P. Berrange2017-10-121-10/+9Star
| | | | | | | | | | | | | | | | | | | | | | The tcp_chr_free_connection & tcp_chr_disconnect methods both skip all of their cleanup work unless the 's->connected' flag is set. This flag is set when the incoming client connection is ready to use. Crucially this is *after* the TLS handshake has been completed. So if the TLS handshake fails and we try to cleanup the failed client, all the cleanup is skipped as 's->connected' is still false. The only important thing that should be skipped in this case is sending of the CHR_EVENT_CLOSED, because we never got as far as sending the corresponding CHR_EVENT_OPENED. Every other bit of cleanup can be robust against being called even when s->connected is false. Signed-off-by: Daniel P.

| * chardev: remove context in chr_update_read_handlerPeter Xu2017-09-225-9/+5Star

| * chardev: use per-dev context for io_add_watch_pollPeter Xu2017-09-224-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was only passed in by chr_update_read_handlers(). However when reconnect, we'll lose that context information. So if a chardev was running on another context (rather than the default context, the NULL pointer), it'll switch back to the default context if reconnection happens. But, it should really stick to the old context. Convert all the callers of io_add_watch_poll() to use the internally cached gcontext. Then the context should be able to survive even after reconnections.

However that may not be enough if the char backend is disconnected and reconnected afterward. There are chardev codes that still assumed the context be NULL (which is the main context). Will fix that up in following up patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * sockets: Rename SocketAddress to SocketAddressLegacyMarkus Armbruster2017-05-092-22/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The next commit will rename SocketAddressFlat to SocketAddress, and the commit after that will replace most uses of SocketAddressLegacy by SocketAddress, replacing most of this commit's renames right back. Note that checkpatch emits a few "line over 80 characters" warnings. The long lines are all temporary; the SocketAddressLegacy replacement will shorten them again.

| * char: Fix removing wrong GSource that be found by fd_in_tagzhanghailiang2017-05-037-33/+26Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
