* rng-random: only build on POSIX platformsAnthony Liguori2012-11-191-1/+2
| | | | | | | There is no /dev/random on win32. Cc: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* rng-egd: don't use gslist_free_fullAnthony Liguori2012-11-161-5/+14
| | | | | | This function was only introduced in glib 2.28.0. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* rng-egd: introduce EGD compliant RNG backendAnthony Liguori2012-11-162-1/+216
| | | | | | | | | | | This backend talks EGD to a CharDriverState. A typical way to invoke this would be: qemu -chardev socket,host=localhost,port=1024,id=chr0 \ -object rng-egd,chardev=chr0,id=egd0 \ -device virtio-rng-pci,rng=egd0 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* rng-random: add an RNG backend that uses /dev/random (v3)Anthony Liguori2012-11-162-1/+162
| | | | | | | | | | | | | | | | | | | The filename can be overridden but it expects a non-blocking source of entropy. A typical invocation would be: qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0 This can also be used with /dev/urandom by using the command line: qemu -object rng-random,filename=/dev/urandom,id=rng0 \ -device virtio-rng-pci,rng=rng0 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - merged header split patch into this one v2 -> v3 - bug fix in rng-random (Paolo)
* rng: add RndBackend abstract object classAnthony Liguori2012-11-162-0/+94
This is the backend used by devices that need to request entropy. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
