2009-10-27net: add receive_raw parameter to qemu_new_vlan_client()Mark McLoughlin
Trivial patch to allow supplying a receive_raw function. A future cleanup should combine this function pointer parameters into a table. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: add an API for 'raw' packetsMark McLoughlin
In the case where a NIC and backend agree on a packet header format, this API allows injecting packets which lack the agreed upon header. We need this for sending our gratuitous ARP. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: add flags parameter to packet queue interfaceMark McLoughlin
This allows for the addition of a raw flag, and leaves the way open for other flags too. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: add tap_has_vnet_hdr() and tap_using_vnet_hdr() APIsMark McLoughlin
These lamely named functions allow virtio-net to query whether IFF_VNET_HDR is enabled on a tap interface and inform the tap code that virtio-net will supply packets with a vnet header. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: add a client type codeMark McLoughlin
This is so as to allow APIs which operate on specific client types without having to add a function table entry which is only implemented by a single client type. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: add a vnet_hdr=on|off parameterMark McLoughlin
This allows people to disable the IFF_VNET_HDR flag, e.g. for debugging purposes or if they know they may migrate the guest to a machine without IFF_VNET_HDR support. It also allows making the lack of IFF_VNET_HDR support an error condition, e.g. in the case where a guest is being migrated from a host which does support it. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: refactor tap initializationMark McLoughlin
Re-factor things so that there is only one call site for net_tap_fd_init(). Two concerns about the QemuOpts usage here - firstly, we set the script arguments to their default value and, secondly, we set the ifname value to the name allocated by the kernel if none is supplied. Are we okay with such things ending up in writeconfig output? Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: enable IFF_VNET_HDR on tap fds if availableMark McLoughlin
For now, we just add an empty header before writing and strip the header after reading. We really only want IFF_VNET_HDR when virtio_net is using it, but it would significantly complicate matters to try and do that. There should be little or no performance impact with always adding headers. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: make tap_receive() re-use tap_receive_iov() codeMark McLoughlin
In future we will want to prepend a virtio_net header if the NIC didn't supply one but IFF_VNET_HDR is enabled on the interface. This is most easily achived by using writev() in all cases. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: import linux tap ioctl definitionsMark McLoughlin
Making features dependent on the availability of newer versions if_tun.h is going to get seriously clumsy, so let's just import the definitions we need. It's only a small handful. If and when we're comfortable depending on 2.6.30 headers, we can remove this again. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27net: remove unused includes of if_tun.h and if_tap.hMark McLoughlin
Looks like these are just artifacts of vl.c being split up. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27Revert "qcow2: Bring synchronous read/write back to life"Kevin Wolf
It was merely a workaround and the real fix is done now. This reverts commit ef845c3bf421290153154635dc18eaa677cecb43. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27linux-aio: Honour AsyncContextKevin Wolf
Also for Linux AIO, don't call callbacks that don't belong to the active AsyncContext. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27posix-aio-compat: Honour AsyncContextKevin Wolf
Don't call callbacks that don't belong to the active AsyncContext. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27block: Use new AsyncContext for bdrv_read/write emulationKevin Wolf
bdrv_read/write emulation is used as the perfect example why we need something like AsyncContexts. So maybe they better start using it. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27Introduce contexts for asynchronous callbacksKevin Wolf
Add the possibility to use AIO and BHs without allowing foreign callbacks to be run. Basically, you put your own AIOs and BHs in a separate context. For details see the comments in the source. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27Split out bottom halvesKevin Wolf
Instead of putting more and more stuff into vl.c, let's have the generic functions that deal with asynchronous callbacks in their own file. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27Add qemu_aio_process_queue()Kevin Wolf
We'll leave some AIO completions unhandled when we can't call the callback. qemu_aio_process_queue() is used later to run any callbacks that are left and can be run then. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27posix-aio-compat: Split out posix_aio_process_queueKevin Wolf
We need to process the request queue and run callbacks separately from reading out the queue in a later patch, so split it out. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
