2012-02-10usb-redir: Add the posibility to filter out certain devices from redirecionHans de Goede
This patch adds the posibility to filter out certain devices from redirecion. To use this pass the filter property to -device usb-redir. The filter property takes a string consisting of filter rules, the format for a rule is: <class>:<vendor>:<product>:<version>:<allow> -1 can be used to allow any value for a field. Muliple rules can be concatonated using | as a separator. Note that if a device matches none of the passed in rules, redirecting it will not be allowed! Example: -device usb-redir,filter='-1:0x0781:0x5567:-1:0|0x08:-1:-1:-1:1' This example will deny the Sandisk Cruzer Blade being redirected, as it has a usb id of 0781:5567, it will allow any other usb mass storage devices, and it will deny any other devices (the default for devices not matching any of the rules.

2012-02-01Add support for net bridgeCorey Bryant
The most common use of -net tap is to connect a tap device to a bridge. This requires the use of a script and running qemu as root in order to allocate a tap device to pass to the script. This model is great for portability and flexibility but it's incredibly difficult to eliminate the need to run qemu as root. The only really viable mechanism is to use tunctl to create a tap device, attach it to a bridge as root, and then hand that tap device to qemu. The problem with this mechanism is that it requires administrator intervention whenever a user wants to create a guest. By essentially writing a helper that implements the most common qemu-ifup script that can be safely given cap_net_admin, we can dramatically simplify things for non-privileged users. We still support existing -net tap options as a mechanism for advanced users and backwards compatibility. Currently, this is very Linux centric but there's really no reason why it couldn't be extended for other Unixes. A typical invocation would be similar to one of the following: qemu linux.img -net bridge -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper" -net nic,model=virtio qemu linux.img -netdev bridge,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 The default bridge that we attach to is br0. The thinking is that a distro could preconfigure such an interface to allow out-of-the-box bridged networking. Alternatively, if a user wants to use a different bridge, a typical invocation would be simliar to one of the following: qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0" -net nic,model=virtio qemu linux.img -netdev bridge,br=qemubr0,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Richa Marwaha <rmarwah@linux.vnet.ibm.com> Signed-off-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-01Add cap reduction support to enable use as SUIDCorey Bryant
The ideal way to use qemu-bridge-helper is to give it an fscap of using: setcap cap_net_admin=ep qemu-bridge-helper Unfortunately, most distros still do not have a mechanism to package files with fscaps applied. This means they'll have to SUID the qemu-bridge-helper binary. To improve security, use libcap to reduce our capability set to just cap_net_admin, then reduce privileges down to the calling user. This is hopefully close to equivalent to fscap support from a security perspective.

2012-02-01Add basic version of bridge helperCorey Bryant
This patch adds a helper that can be used to create a tap device attached to a bridge device. Since this helper is minimal in what it does, it can be given CAP_NET_ADMIN which allows qemu to avoid running as root while still satisfying the majority of what users tend to want to do with tap devices. The way this all works is that qemu launches this helper passing a bridge name and the name of an inherited file descriptor. The descriptor is one end of a socketpair() of domain sockets. This domain socket is used to transmit a file descriptor of the opened tap device from the helper to qemu. The helper can then exit and let qemu use the tap device.

2012-01-06configure: Fix test for supported host CPU typePeter Maydell
The test for whether the host CPU is supported had several problems: * the attempt to fall back to TCI was done as a duplicate test, very late (so "--cpu foo" would fail early but "--cpu unicore32" would fail late, differently, and after configure had already printed a lot of output) * a number of CPUs only supported as guests were included in the list of CPUs we would accept as valid hosts, which would result in a late compile failure on those systems rather than a configure failure or fallback to TCI * bailing out for an unsupported CPU happened before the main option parsing, so "configure --help" wouldn't work Fix these by folding the setting of ARCH into the first test for supported host CPU, removing spurious guest-only CPU names from it, and moving the "fall back to TCI" code earlier.

2011-12-19configure: Improve Xen autodetection for hosts without XenStefan Weil
With this patch, it only takes one test (instead of four) to detect that there is no Xen support at all. For most build hosts, this will reduce the time configure needs. It will also reduce noisy output in config.log. Build hosts with Xen now need up to five (instead of up to four) tests. They get improved diagnostics when Xen support fails.

2011-12-10w32: QEMU applications with SDL are always GUI applicationsStefan Weil
Since commit 1d14ffa97eacd3cb722271eaf6f093038396eac4 (in 2005), QEMU applications on W32 don't use the default SDL compiler flags: Instead of a GUI application, a console application is created. This has disadvantages (there is always an empty console window) and no obvious reason, so this patch removes the strange flag modification. The SDL GUI applications still can be run from a console window and even send stdout and stderr to that console by setting environment variable SDL_STDIO_REDIRECT=no.

2011-12-06configure: Don't mix glib and libcheck testsLuiz Capitulino
test-coroutine is listed as a libcheck test in the 'checks' variable. This is not right because 'make check' won't run test-coroutine if libcheck tests are not enabled (either because libcheck isn't detected or because --disable-check-utests is passed). Tests using the glib test framework are independent from libcheck and afaik are always present (although having a configure switch to disable them is probably worth it). Untangle test-coroutine from the libcheck tests by introducing the 'test_progs' variable and using it to generate the test list used by 'make check'.
