[libvirt] [PATCH 0/5] add usb redirection filter support

BZ RFE https://bugzilla.redhat.com/show_bug.cgi?id=795929 qemu support: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=6af165892cf900291046f1d25f... Since qemu has have the code to support USB redirection filter. This set of patches try to support it from libvirt. The XML format is like this: <devices> ... <redirdev bus='usb' type='spicevmc'> <address type='usb' bus='0' port='4'/> </redirdev> <redirfilter> <usbdev class='0x08' vendor='0x1234' product='0xbeef' \ version='2.00' allow='yes'/> <usbdev class='-1' vendor='-1' product='-1' version='-1' allow='no'/> </redirfilter> ... </devices> Multiple <usbdev> element as one of filter rule could be added into parent element <redirfilter>, only no more than <redirfilter> element could exists. There is no 1:1 mapping between ports and redirected devices and qemu and spicy client couldn't decide into which usbredir ports the client can 'plug' redirected devices. So it make sense to apply all of filter rules global to all existing usb redirection devices. class attribute is USB Class codes. version is bcdDevice value of USB device. vendor and product is USB vendorId and productId. -1 can be used to allow any value for a field. Except allow attribute the other four are optional, default value is -1. The above XML will be converted to the following qemu command line: If there are multiple usb-redir device, all of them have the same filter rules. -device usb-redir,chardev=charredir0,id=redir0,\ filter=0x08:0x1234:0xBEEF:0x2000:1|-1:-1:-1:-1:0,bus=usb.0,port=4 Guannan Ren(0/5) qemu: add usb-redir.filter qemu capability flag qemu: define and parse USB redirection filter XML qemu: build USB redirection filter qemu command line test: add xml2argvtest for usb-redir filter and update doc: update usb redirection filter infomation on docs/formatdomain.html.in | 38 ++- docs/schemas/domaincommon.rng | 66 ++++ src/conf/domain_conf.c | 346 ++++++++++++++++++++ src/conf/domain_conf.h | 21 ++ src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 45 +++- src/qemu/qemu_command.h | 5 +- src/qemu/qemu_hotplug.c | 3 +- .../qemuxml2argv-usb-redir-filter.args | 10 + .../qemuxml2argv-usb-redir-filter.xml | 45 +++ tests/qemuxml2argvtest.c | 6 + 12 files changed, 571 insertions(+), 19 deletions(-)
