2018-04-10e1000: Choose which set of props to migrateDr. David Alan Gilbert1-1/+17
When we're using the subsection we migrate both the 'props' and 'tso_props' data; when we're not using the subsection (to migrate to 2.11 or old machine types) we've got to choose what to migrate in the main structure. If we're using the subsection migrate 'props' in the main structure. If we're not using the subsection then migrate the last one that changed, which gives behaviour similar to the old behaviour.

2018-04-10e1000: Dupe offload data on reading old streamDr. David Alan Gilbert1-0/+16
Old QEMUs only had one set of offload data; when we only receive one lot, dupe the received data - that should give us about the same bug level as the old version. Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2018-04-10e1000: Convert v3 fields to subsectionDr. David Alan Gilbert1-12/+22
A bunch of new TSO fields were introduced by d62644b4 and this bumped the VMState version; however it's easier for those trying to keep backwards migration compatibility if these fields are added in a subsection instead. Move the new fields to a subsection. Since this was added after 2.11, this change will only affect compatbility with 2.12-rc0.

The CAN devices can currently be used to crash QEMU, e.g.: $ x86_64-softmmu/qemu-system-x86_64 -device kvaser_pci Segmentation fault (core dumped) So we've got to add a proper check here that the corresponding bus is available.

2018-03-26virtio_net: flush uncompleted TX on resetGreg Kurz1-0/+11
If the backend could not transmit a packet right away for some reason, the packet is queued for asynchronous sending. The corresponding vq element is tracked in the async_tx.elem field of the VirtIONetQueue, for later freeing when the transmission is complete. If a reset happens before completion, virtio_net_tx_complete() will push async_tx.elem back to the guest anyway, and we end up with the inuse flag of the vq being equal to -1. The next call to virtqueue_pop() is then likely to fail with "Virtqueue size exceeded". This can be reproduced easily by starting a guest with an hubport backend that is not connected to a functional network, eg, -device virtio-net-pci,netdev=hub0 -netdev hubport,id=hub0,hubid=0 and no other -netdev hubport,hubid=0 on the command line. The appropriate fix is to ensure that such an asynchronous transmission cannot survive a device reset. So for all queues, we first try to send the packet again, and eventually we purge it if the backend still could not deliver it. CC: qemu-stable@nongnu.org Reported-by: R.

2018-03-19fsl-imx6: Swap Ethernet interrupt definesGuenter Roeck1-1/+27
The sabrelite machine model used by qemu-system-arm is based on the Freescale/NXP i.MX6Q processor. This SoC has an on-board ethernet controller which is supported in QEMU using the imx_fec.c module (actually called imx.enet for this model.) The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the imx.enet device like this: #define FSL_IMX6_ENET_MAC_1588_IRQ 118 #define FSL_IMX6_ENET_MAC_IRQ 119 According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf, page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary, interrupts are as follows. 150 ENET MAC 0 IRQ 151 ENET MAC 0 1588 Timer interrupt where 150 - 32 == 118 151 - 32 == 119 In other words, the vector definitions in the fsl-imx6.h file are reversed. Fixing the interrupts alone causes problems with older Linux kernels: The Ethernet interface will fail to probe with Linux v4.9 and earlier. Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe error handling. This is a Linux kernel problem, not a qemu problem: the Linux kernel only worked by accident since it requested both interrupts. For backward compatibility, generate the Ethernet interrupt on both interrupt lines. This was shown to work from all Linux kernel releases starting with v3.16.

2018-03-13virtio-net: add linkspeed and duplex settings to virtio-netJason Baron1-0/+26
Although linkspeed and duplex can be set in a linux guest via 'ethtool -s', this requires custom ethtool commands for virtio-net by default. Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows the hypervisor to export a linkspeed and duplex setting. The user can subsequently overwrite it later if desired via: 'ethtool -s'. Linkspeed and duplex settings can be set as: '-device virtio-net,speed=10000,duplex=full' where speed is [0...INT_MAX], and duplex is ["half"|"full"].

In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

2018-01-25i.MX: Fix FEC/ENET receive funtionsJean-Christophe Dubois1-6/+2
The actual imx_eth_enable_rx() function is buggy. It updates s->regs[ENET_RDAR] after calling qemu_flush_queued_packets(). qemu_flush_queued_packets() is going to call imx_XXX_receive() which itself is going to call imx_eth_enable_rx(). By updating s->regs[ENET_RDAR] after calling qemu_flush_queued_packets() we end up updating the register with an outdated value which might lead to disabling the receive function in the i.MX FEC/ENET device. This patch change the place where the register update is done so that the register value stays up to date and the receive function can keep running.

2018-01-16maint: Fix macros with broken 'do/while(0); ' usageEric Blake1-1/+1
The point of writing a macro embedded in a 'do { ... } while (0)' loop (particularly if the macro has multiple statements or would otherwise end with an 'if' statement) is so that the macro can be used as a drop-in statement with the caller supplying the trailing ';'. Although our coding style frowns on brace-less 'if': if (cond) statement; else something else; that is the classic case where failure to use do/while(0) wrapping would cause the 'else' to pair with any embedded 'if' in the macro rather than the intended outer 'if'. But conversely, if the macro includes an embedded ';', then the same brace-less coding style would now have two statements, making the 'else' a syntax error rather than pairing with the outer 'if'. Thus, even though our coding style with required braces is not impacted, ending a macro with ';' makes our code harder to port to projects that use brace-less styles. The change should have no semantic impact. I was not able to fully compile-test all of the changes (as some of them are examples of the ugly bit-rotting debug print statements that are completely elided by default, and I didn't want to recompile with the necessary -D witnesses - cleaning those up is left as a bite-sized task for another day); I did, however, audit that for all files touched, all callers of the changed macros DID supply a trailing ';' at the callsite, and did not appear to be used as part of a brace-less conditional. Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\ Signed-off-by: Eric Blake <eblake@redhat.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Reviewed-by: Michael S.

2018-01-16net: Drop unusual use of do { } while (0);Eric Blake1-10/+10
For a couple of macros in pcnet.c, we have to provide a new scope to avoid compiler warnings about declarations in the middle of a switch statement that aren't in a sub-scope. But use of 'do { ... } while (0);' merely to provide that new scope is arcane overkill, compared to just using '{ ... }'.

2018-01-11imx_fec: Change queue flushing heuristicsAndrey Smirnov1-6/+6
In current implementation, packet queue flushing logic seem to suffer from a deadlock like scenario if a packet is received by the interface before before Rx ring is initialized by Guest's driver. Consider the following sequence of events: 1. A QEMU instance is started against a TAP device on Linux host, running Linux guest, e. g., something to the effect of: qemu-system-arm \ -net nic,model=imx.fec,netdev=lan0 \ netdev tap,id=lan0,ifname=tap0,script=no,downscript=no \ ... rest of the arguments ... 2. Once QEMU starts, but before guest reaches the point where FEC deriver is done initializing the HW, Guest, via TAP interface, receives a number of multicast MDNS packets from Host (not necessarily true for every OS, but it happens at least on Fedora 25) 3. Recieving a packet in such a state results in imx_eth_can_receive() returning '0', which in turn causes tap_send() to disable corresponding event (tap.c:203) 4. Once Guest's driver reaches the point where it is ready to recieve packets it prepares Rx ring descriptors and writes ENET_RDAR_RDAR to ENET_RDAR register to indicate to HW that more descriptors are ready. And at this points emulation layer does this: s->regs[index] = ENET_RDAR_RDAR; imx_eth_enable_rx(s); which, combined with: if (!s->regs[ENET_RDAR]) { qemu_flush_queued_packets(qemu_get_queue(s->nic)); } results in Rx queue never being flushed and corresponding I/O event beign disabled. To prevent the problem, change the code to always flush packet queue when ENET_RDAR transitions 0 -> ENET_RDAR_RDAR.
