2012-03-18Sparc: avoid AREG0 wrappers for memory access helpersBlue Swirl1-0/+7
Adjust generation of load and store templates so that the functions take a parameter for CPUState instead of relying on global env. Remove wrappers. Move remaining memory helpers to ldst_helper.c. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-03-14qom: Introduce CPU classAndreas Färber1-0/+1
Reintroduce CPUState as QOM object: It's abstract and derived directly from TYPE_OBJECT for compatibility with the user emulators. The identifier CPUState avoids conflicts between CPU() and the struct. Introduce $(qom-twice-y) to build it separately for system and for user emulators. Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper. Signed-off-by: Andreas Färber <afaerber@suse.de> Reviewed-by: Anthony Liguori <aliguori@us.ibm.com>

2012-03-08osdep: Remove local definition of macro offsetofStefan Weil1-14/+0
The macro offsetof is defined in stddef.h. It is conforming to the standards C89, C99 and POSIX.1-2001 (see man page), so it is a sufficiently old standard. Therefore chances are very high that QEMU never needs a local definition of this macro. osdep.h already includes stddef.h, so this patch simply removes the unneeded code from the files configure and osdep.h. If we ever need the local definition again, it should be added to compiler.h (the macro is usually provided with the compiler, it is not OS specific).

2012-02-24configure: Check whether makecontext() is a glibc stub functionPeter Maydell1-0/+4

Make the configure test for makecontext() also check for the presence of the __stub_makecontext macro which indicates the presence of these stubs, so we can avoid trying to use them and fall back to a different coroutine implementation instead.

2012-02-10usb-redir: Add the posibility to filter out certain devices from redirecionHans de Goede1-1/+1
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 Bryant1-0/+2
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 Bryant1-0/+34
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 Bryant1-0/+1
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 Maydell1-23/+21
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.
