2013-06-14create qemu_openpty_raw() helper function and move it to a separate fileMichael Tokarev1-72/+5
In two places qemu uses openpty() which is very system-dependent, and in both places the pty is switched to raw mode as well. Make a wrapper function which does both steps, and move all the system-dependent complexity into a separate file, together with static/local implementations of openpty() and cfmakeraw() from qemu-char.c. It is in a separate file, not part of oslib-posix.c, because openpty() often resides in -lutil which is not linked to every program qemu builds. This change removes #including of <pty.h>, <termios.h> and other rather specific system headers out of qemu-common.h, which isn't a place for such specific headers really. This version has been verified to build correctly on Linux, OpenBSD, FreeBSD and OpenIndiana. On the latter it lets qemu to be built with gtk gui which were not possible there due to missing openpty() and cfmakeraw().

2013-06-10qemu-char: don't issue CHR_EVENT_OPEN in a BHMichael Roth1-21/+17
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET, and it was issued as a bottom-half: 86e94dea5b740dad65446c857f6959eae43e0ba6 Which we basically used to print out a greeting/prompt for the monitor. AFAICT the only reason this was ever done in a BH was because in some cases we'd modify the chr_write handler for a new chardev backend *after* the site where we issued the reset (see: 86e94d:qemu_chr_open_stdio()) At some point this event was renamed to CHR_EVENT_OPENED, and we've maintained the use of this BH ever since. However, due to 9f939df955a4152aad69a19a77e0898631bb2c18, we schedule the BH via g_idle_add(), which is causing events to sometimes be delivered after we've already begun processing data from backends, leading to: known bugs: QMP: session negotation resets with OPENED event, in some cases this is causing new sessions to get sporadically reset potential bugs: hw/usb/redirect.c: can_read handler checks for dev->parser != NULL, which may be true if CLOSED BH has not been executed yet. In the past, OPENED quiesced outstanding CLOSED events prior to us reading client data. If it's delayed, our check may allow reads to occur even though we haven't processed the OPENED event yet, and when we do finally get the OPENED event, our state may get reset. qtest.c: can begin session before OPENED event is processed, leading to a spurious reset of the system and irq_levels gdbstub.c: may start a gdb session prior to the machine being paused To fix these, let's just drop the BH. Since the initial reasoning for using it still applies to an extent, work around that by deferring the delivery of CHR_EVENT_OPENED until after the chardevs have been fully initialized, toward the end of qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This defers delivery long enough that we can be assured a CharDriverState is fully initialized before CHR_EVENT_OPENED is sent. Also, rather than requiring each chardev to do an explicit open, do it automatically, and allow the small few who don't desire such behavior to suppress the OPENED-on-init behavior by setting a 'explicit_be_open' flag. We additionally add missing OPENED events for stdio backends on w32, which were previously not being issued, causing us to not recieve the banner and initial prompts for qmp/hmp.

While reviewing some patches I found this problem where tcp_chr_accept does not clear listen_tag when returning FALSE, leading to a double g_source_remove of the underlying source. Not really a problem unless the id gets re-used in between, but still something we should fix.

2013-04-22qemu-char: do not operate on sources from finalize callbacksPaolo Bonzini1-15/+40
Due to a glib bug, the finalize callback is called with the GMainContext lock held. Thus, any operation on the context from the callback will cause recursive locking and a deadlock. This happens, for example, when a client disconnects from a socket chardev. The fix for this is somewhat ugly, because we need to forego polymorphism and implement our own function to destroy IOWatchPoll sources. The right thing to do here would be child sources, but we support older glib versions that do not have them. Not coincidentially, glib developers found and fixed the deadlock as part of implementing child sources.

Even if a CharDriverState's source is blocked by the front-end, it must not be dropped. The IOWatchPoll that wraps it will take care of adding and removing it to the main loop. Only remove the source when the channel is closed; and in that case, make sure that the wrapping IOWatchPoll is removed too. These should just be theoretical bugs.

2013-04-22qemu-char: simplify pty pollingPaolo Bonzini1-24/+17
There is no need to use a timer and pty_chr_read to detect a connected pty. It is simpler to just call g_poll periodically and check for POLLHUP. It is done once per second, and only if the pty is disconnected, so it is cheap enough. Tested with "-monitor pty" and "-serial mon:pty", both of which work correctly and do not freeze QEMU.

After attaching the source, we have to remove the reference we hold to it, because we do not hold anymore a pointer to the source. If we do not do this, removing the source will not finalize it and will not drop the "real" I/O watch source. This showed up when backporting the new flow control patches to older versions of QEMU that still used select. The whole select then failed with EBADF (poll instead will reporting POLLNVAL on a single pollfd) and QEMU froze.

2013-04-08qemu-char: really fix behavior on can_read = 0Paolo Bonzini1-4/+13
I misread the glib manual, g_source_remove does not let you re-attach the source later. This behavior (called "blocking" the source in glib) is present in glib's source code, but private and not available outside glib; hence, we have to resort to re-creating the source every time. In fact, g_source_remove and g_source_destroy are the same thing, except g_source_destroy is O(1) while g_source_remove scans a potentially very long list of GSources in the current main loop. Ugh. Better use g_source_destroy explicitly, and leave "tags" to those dummies who cannot track their pointers' lifetimes.

2013-04-05qemu-char: eliminate busy waiting on can_read returning zeroPaolo Bonzini1-43/+19
The character backend refactoring introduced an undesirable busy wait. The busy wait happens if can_read returns zero and there is data available on the character device's file descriptor. Then, the I/O watch will fire continuously and, with TCG, the CPU thread will never run. 1) Char backend asks front end if it can write 2) Front end says no 3) poll() finds the char backend's descriptor is available 4) Goto (1) What we really want is this (note that step 3 avoids the busy wait): 1) Char backend asks front end if it can write 2) Front end says no 3) poll() goes on without char backend's descriptor 4) Goto (1) until qemu_chr_accept_input() called 5) Char backend asks front end if it can write 6) Front end says yes 7) poll() finds the char backend's descriptor is available 8) Backend handler called After this patch, the IOWatchPoll source and the watch source are separated. The IOWatchPoll is simply a hook that runs during the prepare phase on each main loop iteration. The hook adds/removes the actual source depending on the return value from can_read. A simple reproducer is qemu-system-i386 -serial mon:stdio ... followed by banging on the terminal as much as you can. :) Without this patch, emulation will hang.

chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail.

2013-04-02chardev: clear O_NONBLOCK on SCM_RIGHTS file descriptorsStefan Hajnoczi1-0/+3
When we receive a file descriptor over a UNIX domain socket the O_NONBLOCK flag is preserved. Clear the O_NONBLOCK flag and rely on QEMU file descriptor users like migration, SPICE, VNC, block layer, and others to set non-blocking only when necessary. This change ensures we don't accidentally expose O_NONBLOCK in the QMP API. QMP clients should not need to get the non-blocking state "correct". A recent real-world example was when libvirt passed a non-blocking TCP socket for migration where we expected a blocking socket. The source QEMU produced a corrupted migration stream since its code did not cope with non-blocking sockets.
