* usb-host: use qdev for -usbdevice + rework.Gerd Hoffmann2009-10-301-266/+144
| | | | | | | | | | | | | | | Changes: * We don't create/delete devices, we attach/detach them instead. * The separate autofilter list is gone, we simply walk the list of devices directly instead. * Autofiltering is done unconditionally now. Non-auto device scan code got dropped. * Autofiltering turns off the timer if there is nothing to do, it runs only in case there are unattached host devices.

* usb-linux: return USB_RET_STALL on -EPIPEPaul Bolle2009-10-271-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 0) This is an attempt to get an issue in usb-linux.c, for which a patch was posted about a year ago, finally fixed. 1) Mark Burkley submitted a "EHCI emulation module" for review in in October 2008 (see: http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01326.html). No EHCI emulation module was ever committed to qemu. 2) Part of that (large) patch was a fix for a separate issue in usb-linux.c. Max Krasnyansky has ACK'ed that fix (see: http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00032.html). 3) I already asked whether this fix was ready to be committed in last April (see: http://lists.gnu.org/archive/html/qemu-devel/2009-04/msg01763.html) 4) Maybe submitting this fix as a separate patch (with a really long commit message but without a Signed-off-by) and cc-ing everbody involved will help if actually getting this issue fixed.

* usb-linux.c: fix buffer overflowJim Paris2009-09-111-2/+10
| | | | | | | | | | | | | | | | | | | | In usb-linux.c:usb_host_handle_control, we pass a 1024-byte buffer and length to the kernel. However, the length was provided by the caller of dev->handle_packet, and is not checked, so the kernel might provide too much data and overflow our buffer. For example, hw/usb-uhci.c could set the length to 2047. hw/usb-ohci.c looks like it might go up to 4096 or 8192. This causes a qemu crash, as reported here: http://www.mail-archive.com/kvm@vger.kernel.org/msg18447.html This patch increases the usb-linux.c buffer size to 2048 to fix the specific device reported, and adds a check to avoid the overflow in any case.

| | | | | | | | | | | | | | | | | | Scanning for devices via /sys/bus/usb/devices/ and using them via the /dev/bus/usb/<bus>/<device> character devices is the prefered method on modern kernels, so try that first. When using SELinux and libvirt, qemu will have access to /sys/bus/usb but not /proc/bus/usb, so although the current code will work just fine, it will generate SELinux AVC warnings.

| | | | | | | | | | | Add in a workaround to allow the usb serial devices to work with the usb pass through mechanism. The ioctl() to request an alternate interface will always return < 0 for a usb-serial device based on the kernel driver. This means there is no alternate interface end point.

* monitor: Rework API (Jan Kiszka)aliguori2009-03-051-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

* usb: Support for removing device by host addr, improved auto filter syntax ↵aliguori2008-09-141-31/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Max Krasnyansky) This patch adds support for removing USB devices by host address. Which is usefull for things like libvirtd because there is no easy way to find guest USB address of the host device. In other words you can now do: usb_add host:3.5 ... usb_del host:3.5 Before the patch 'usb_del' did not support 'host:' notation. ---- Syntax for specifying auto connect filters has been improved. Old syntax was host:bus.dev host:pid:vid New syntax is host:auto:bus.dev[:pid:vid] In both the cases any attribute can be set to "*". New syntax is more flexible and lets you do things like host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */ It's now possible to remove auto filters. For example: usb_del host:auto:3.*:5533:* Active filters are printed after all host devices in 'info usb' output. Which now looks like this: Device 1.1, speed 480 Mb/s Hub: USB device 1d6b:0002, EHCI Host Controller Device 1.4, speed 480 Mb/s Class 00: USB device 1058:0704, External HDD Auto filters: Device 3.* ID *:* Signed-off-by: Max Krasnyansky <maxk@kernel.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5205 c046a42c-6fe2-441c-8c8c-71466251a162
* husb: Make control transactions asynchronous (Max Krasnyansky)aliguori2008-09-141-93/+371
| | | | | | | | | | | | | | | | | | | | | USB is 99.8% async now :). 0.2% is the three control requests that we need to execute synchronously. We could off-load that to a thread or something but it's not worth the pain since those requests are performed only during device initialization (ie when device is connected to the VM). The change is a bit bigger than I wanted due to the fact that generic handle_packet()/handle_control() interface was not designed for async transactions. So I ended up adding custom handle_packet() code to usb-linux. We can make that generic if/when some other component needs it.

* husb: rewrite Linux host USB layer, fully async operation (Max Krasnyansky)aliguori2008-08-211-278/+182
| | | | | | | | | | | | | | | | | This is a follow up to the async UHCI patch. Both BULK and ISOC transactions are now fully asynchrounous. I left CONTROL synchronous for now, ideally we want it to be async too and it should not be that hard to do now. This patch obviously requires UHCI patch. The combo has been tested with various devices. See the UHCI patch description for list of the devices. Most of the testing was done with the KVM flavor of QEMU.

* husb: support for USB host device auto connect (Max Krasnyansky)aliguori2008-08-211-14/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QEMU can now automatically grab host USB devices that match the filter. For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle wildcards. So for example if you do something like usb_add host:5.* QEMU will automatically grab any non-hub device with host address 5.*. Same with the 'host:PID:*', we grab any device that matches PID. Filtering itself is very generic so we can probably add more elaborate syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'. Anyway, it's implemented using a periodic timer that scans host devices and grabs those that match the filter. Timer is started when the first filter is added. We now keep the list of all host devices that we grabbed to make sure that we do not grab the same device twice. btw It's currently possible to grab the same host device more than once. ie You can just do "usb_add host:1.1" more than once, which of course does not work. So this patch fixes that issue too. Along with auto disconnect patch that I send a minute ago the setup is very seamless now. You can just allocate some usb ports to the VMs and plug/unplug devices at any time.

* husb: support for USB host device auto disconnect (Max Krasnyansky)aliguori2008-08-211-9/+47
| | | | | | | | | | | | | | | | | | | | | | I got really annoyed by the fact that you have to manually do usb_del in the monitor when host device is unplugged and decided to fix it :) Basically we now automatically remove guest USB device when the actual host device is disconnected. At first I've extended set_fd_handlerX() stuff to support checking for exceptions on fds. But unfortunately usbfs code does not wake up user-space process when device is removed, which means we need a timer to periodically check if device is still there. So I removed fd exception stuff and implemented it with the timer.
