2020-01-08chardev: Use QEMUChrEvent enum in IOEventHandler typedefPhilippe Mathieu-Daudé1-3/+3
The Chardev events are listed in the QEMUChrEvent enum. By using the enum in the IOEventHandler typedef we: - make the IOEventHandler type more explicit (this handler process out-of-band information, while the IOReadHandler is in-band), - help static code analyzers. This patch was produced with the following spatch script: @match@ expression backend, opaque, context, set_open; identifier fd_can_read, fd_read, fd_event, be_change; @@ qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event, be_change, opaque, context, set_open); @depends on match@ identifier opaque, event; identifier match.fd_event; @@ static -void fd_event(void *opaque, int event) +void fd_event(void *opaque, QEMUChrEvent event) { ... } Then the typedef was modified manually in include/chardev/char-fe.h.

2019-02-12tests: expand coverage of socket chardev testDaniel P. Berrangé1-165/+475
The current socket chardev tests try to exercise the chardev socket driver in both server and client mode at the same time. The chardev API is not very well designed to handle both ends of the connection being in the same process so this approach makes the test case quite unpleasant to deal with. This splits the tests into distinct cases, one to test server socket chardevs and one to test client socket chardevs. In each case the peer is run in a background thread using the simpler QIOChannelSocket APIs. The main test case code can now be written in a way that mirrors the typical usage from within QEMU. In doing this recfactoring it is possible to greatly expand the test coverage for the socket chardevs to test all combinations except for a server operating in blocking wait mode.

The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *. Note that the new macros evaluate their argument exactly once, thus no need to shout them.

2018-03-13char: allow passing pre-opened socket file descriptor at startupDaniel P. Berrange1-3/+44
When starting QEMU management apps will usually setup a monitor socket, and then open it immediately after startup. If not using QEMU's own -daemonize arg, this process can be troublesome to handle correctly. The mgmt app will need to repeatedly call connect() until it succeeds, because it does not know when QEMU has created the listener socket. If can't retry connect() forever though, because an error might have caused QEMU to exit before it even creates the monitor. The obvious way to fix this kind of problem is to just pass in a pre-opened socket file descriptor for the QEMU monitor to listen on. The management app can now immediately call connect() just once. If connect() fails it knows that QEMU has exited with an error. The SocketAddress(Legacy) structs allow for FD passing via the monitor, and now via inherited file descriptors from the process that spawned QEMU. The final missing piece is adding a 'fd' parameter in the socket chardev options. This allows both HMP usage, pass any FD number with SCM_RIGHTS, then running HMP commands: getfd myfd chardev-add socket,fd=myfd Note that numeric FDs cannot be referenced directly in HMP, only named FDs. And also CLI usage, by leak FD 3 from parent by clearing O_CLOEXEC, then spawning QEMU with -chardev socket,fd=3,id=mon -mon chardev=mon,mode=control Note that named FDs cannot be referenced in CLI args, only numeric FDs. We do not wire this up in the legacy chardev syntax, so you cannot use FD passing with '-qmp', you must use the modern '-mon' + '-chardev' pair. When passing pre-opened FDs there is a restriction on use of TLS encryption. It can be used on a server socket chardev, but cannot be used for a client socket chardev. This is because when validating a server's certificate, the client needs to have a hostname available to match against the certificate identity. An illustrative example of usage is: #!/usr/bin/perl use IO::Socket::UNIX; use Fcntl; unlink "/tmp/qmp"; my $srv = IO::Socket::UNIX->new( Type => SOCK_STREAM(), Local => "/tmp/qmp", Listen => 1, ); my $flags = fcntl $srv, F_GETFD, 0; fcntl $srv, F_SETFD, $flags & ~FD_CLOEXEC; my $fd = $srv->fileno(); exec "qemu-system-x86_64", \ "-chardev", "socket,fd=$fd,server,nowait,id=mon", \ "-mon", "chardev=mon,mode=control"; Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2018-03-12chardev: introduce chr_machine_done hookPeter Xu1-1/+0
Introduce ChardevClass.chr_machine_done() hook so that chardevs can run customized procedures after machine init. There was an existing mux user already that did similar thing but used a raw machine done notifier. Generalize it into a framework, and let the mux chardevs provide such a class-specific hook to achieve the same thing. Then we can move the mux related code to the char-mux.c file. Since at it, replace the mux_realized variable with the global machine_init_done varible. This notifier framework will be further leverged by other type of chardevs soon.

The loop in test-char.c copied the old QEMU main_loop() code, but here the nonblocking check has never been necessary because this standalone test case doesn't hold the I/O lock anyway.

This simplifies removing a backend for a frontend user (no need to retrieve the associated driver and separate delete call etc). NB: many frontends have questionable handling of ending a chardev. They should probably delete the backend to prevent broken reusage. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
2017-06-02char: move CharBackend handling in char-fe unitMarc-André Lureau1-1/+1
Move all the frontend struct and methods to a seperate unit. This avoids accidentally mixing backend and frontend calls, and helps with readabilty. Make qemu_chr_replay() a macro shared by both char and char-fe. Export qemu_chr_write(), and use a macro for qemu_chr_write_all() (nb: yes, CharBackend is for char frontend :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

2017-05-09sockets: Limit SocketAddressLegacy to external interfacesMarkus Armbruster1-3/+2
SocketAddressLegacy is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. SocketAddress is the equivalent flat union. Convert all users of SocketAddressLegacy to SocketAddress, except for existing external interfaces. See also commit fce5d53..9445673 and 85a82e8..c5f1ae3.
