2019-05-17e1000: Never increment the RX undersize count registerChris Kenna
In situations where e1000 receives an undersized Ethernet frame, QEMU increments the emulated "Receive Undersize Count (RUC)" register when padding the frame. This is incorrect because this an expected scenario (e.g. with VLAN tag stripping) and not an error. As such, QEMU should not increment the emulated RUC.

2019-05-17vhost_net: don't set backend for the uninitialized virtqueueJason Wang
We used to set backend unconditionally, this won't work for some guests (e.g windows driver) who may not initialize all virtqueues. For kernel backend, this will fail since it may try to validate the rings during setting backend. Fixing this by simply skipping the backend set when we find desc is not ready.

2019-03-29e1000: Delay flush queue when receive RCTLyuchenlin
Due to too early RCT0 interrput, win10x32 may hang on booting. This problem can be reproduced by doing power cycle on win10x32 guest. In our environment, we have 10 win10x32 and stress power cycle.

2019-03-12spapr: Use CamelCase properlyDavid Gibson
The qemu coding standard is to use CamelCase for type and structure names, and the pseries code follows that... sort of. There are quite a lot of places where we bend the rules in order to preserve the capitalization of internal acronyms like "PHB", "TCE", "DIMM" and most commonly "sPAPR". That was a bad idea - it frequently leads to names ending up with hard to read clusters of capital letters, and means they don't catch the eye as type identifiers, which is kind of the point of the CamelCase convention in the first place. In short, keeping type identifiers look like CamelCase is more important than preserving standard capitalization of internal "words". So, this patch renames a heap of spapr internal type names to a more standard CamelCase. In addition to case changes, we also make some other identifier renames: VIOsPAPR* -> SpaprVio* The reverse word ordering was only ever used to mitigate the capital cluster, so revert to the natural ordering. VIOsPAPRVTYDevice -> SpaprVioVty VIOsPAPRVLANDevice -> SpaprVioVlan Brevity, since the "Device" didn't add useful information sPAPRDRConnector -> SpaprDrc sPAPRDRConnectorClass -> SpaprDrcClass Brevity, and makes it clearer this is the same thing as a "DRC" mentioned in many other places in the code This is 100% a mechanical search-and-replace patch. It will, however, conflict with essentially any and all outstanding patches touching the spapr code. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2019-02-21vhost-net-user: add stubs for when no virtio-net device is presentPaolo Bonzini
hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the vhost-user code is always compiled into QEMU, only the constructor net_init_vhost_user is unreachable. Also, net/vhost-user.c needs functions declared in hw/virtio/vhost-stub.c even if no virtio device exists. Break this dependency. First, add a minimal version of net/vhost-user.c, with no functionality and no dependency on vhost code. Second, #ifdef out the calls back to net/vhost-user.c from hw/net/vhost_net.c. While at it, this patch fixes the CONFIG_VHOST_NET_USE*D* typo.

2019-02-21vhost-net: move stubs to a separate filePaolo Bonzini
There is no reason for CONFIG_VHOST_NET to be specific to a single target; it is a host feature that can be add to all targets, as long as they support the virtio-net device. Currently CONFIG_VHOST_NET depends on CONFIG_KVM, but ioeventfd support is present in the core memory API and works with other accelerators as well. As a first step, move the vhost-net stubs to a separate file. Later, they will become conditional on CONFIG_VIRTIO_NET, which is not available in .c files.

2019-01-17virtio-net: support RSC v4/v6 tcp traffic for Windows HCKYuri Benditovich
This commit adds implementation of RX packets coalescing, compatible with requirements of Windows Hardware compatibility kit. The device enables feature VIRTIO_NET_F_RSC_EXT in host features if it supports extended RSC functionality as defined in the specification. This feature requires at least one of VIRTIO_NET_F_GUEST_TSO4, VIRTIO_NET_F_GUEST_TSO6. Windows guest driver acks this feature only if VIRTIO_NET_F_CTRL_GUEST_OFFLOADS is also present. If the guest driver acks VIRTIO_NET_F_RSC_EXT feature, the device coalesces TCPv4 and TCPv6 packets (if respective VIRTIO_NET_F_GUEST_TSO feature is on, populates extended RSC information in virtio header and sets VIRTIO_NET_HDR_F_RSC_INFO bit in header flags. The device does not recalculate checksums in the coalesced packet, so they are not valid. In this case: All the data packets in a tcp connection are cached to a single buffer in every receive interval, and will be sent out via a timer, the 'virtio_net_rsc_timeout' controls the interval, this value may impact the performance and response time of tcp connection, 50000(50us) is an experience value to gain a performance improvement, since the whql test sends packets every 100us, so '300000(300us)' passes the test case, it is the default value as well, tune it via the command line parameter 'rsc_interval' within 'virtio-net-pci' device, for example, to launch a guest with interval set as '500000': 'virtio-net-pci,netdev=hostnet1,bus=pci.0,id=net1,mac=00, guest_rsc_ext=on,rsc_interval=500000' The timer will only be triggered if the packets pool is not empty, and it'll drain off all the cached packets. 'NetRscChain' is used to save the segments of IPv4/6 in a VirtIONet device. A new segment becomes a 'Candidate' as well as it passed sanity check, the main handler of TCP includes TCP window update, duplicated ACK check and the real data coalescing. An 'Candidate' segment means: 1. Segment is within current window and the sequence is the expected one. 2. 'ACK' of the segment is in the valid window. Sanity check includes: 1. Incorrect version in IP header 2. An IP options or IP fragment 3. Not a TCP packet 4. Sanity size check to prevent buffer overflow attack. 5. An ECN packet Even though, there might more cases should be considered such as ip identification other flags, while it breaks the test because windows set it to the same even it's not a fragment. Normally it includes 2 typical ways to handle a TCP control flag, 'bypass' and 'finalize', 'bypass' means should be sent out directly, while 'finalize' means the packets should also be bypassed, but this should be done after search for the same connection packets in the pool and drain all of them out, this is to avoid out of order fragment. All the 'SYN' packets will be bypassed since this always begin a new' connection, other flags such 'URG/FIN/RST/CWR/ECE' will trigger a finalization, because this normally happens upon a connection is going to be closed, an 'URG' packet also finalize current coalescing unit. Statistics can be used to monitor the basic coalescing status, the 'out of order' and 'out of window' means how many retransmitting packets, thus describe the performance intuitively. Difference between ip v4 and v6 processing: Fragment length in ipv4 header includes itself, while it's not included for ipv6, thus means ipv6 can carry a real 65535 payload. Note that main goal of implementing this feature in software is to create reference setup for certification tests. In such setups guest migration is not required, so the coalesced packets not yet delivered to the guest will be lost in case of migration.

2019-01-14xen: re-name XenDevice to XenLegacyDevice...Paul Durrant
...and xen_backend.h to xen-legacy-backend.h Rather than attempting to convert the existing backend infrastructure to be QOM compliant (which would be hard to do in an incremental fashion), subsequent patches will introduce a completely new framework for Xen PV backends. Hence it is necessary to re-name parts of existing code to avoid name clashes. The re-named 'legacy' infrastructure will be removed once all backends have been ported to the new framework. This patch is purely cosmetic. No functional change.
