Most files that have TABs only contain a handful of them. Change them to spaces so that we don't confuse people. disas, standard-headers, linux-headers and libdecnumber are imported from other projects and probably should be exempted from the check.

2017-12-05pci: Eliminate redundant PCIDevice::bus pointerDavid Gibson1-1/+1
The bus pointer in PCIDevice is basically redundant with QOM information. It's always initialized to the qdev_get_parent_bus(), the only difference is the type. Therefore this patch eliminates the field, instead creating a pci_get_bus() helper to do the type mangling to derive it conveniently from the QOM Device object underneath.

2017-11-20hw/net/vmxnet3: Fix code to work on big endian hosts, tooThomas Huth1-10/+36
Since commit ab06ec43577177a442e8 we test the vmxnet3 device in the pxe-tester, too (when running "make check SPEED=slow"). This now revealed that the code is not working there if the host is a big endian machine (for example ppc64 or s390x) - "make check SPEED=slow" is now failing on such hosts. The vmxnet3 code lacks endianness conversions in a couple of places. Interestingly, the bitfields in the structs in vmxnet3.h already tried to take care of the *bit* endianness of the C compilers - but the code missed to change the *byte* endianness when reading or writing the corresponding structs. So the bitfields are now wrapped into unions which allow to change the byte endianness during runtime with the non-bitfield member of the union. With these changes, "make check SPEED=slow" now properly works on big endian hosts, too.

2017-11-20net: Transmit zero UDP checksum as 0xFFFFEd Swierk1-1/+2
The checksum algorithm used by IPv4, TCP and UDP allows a zero value to be represented by either 0x0000 and 0xFFFF. But per RFC 768, a zero UDP checksum must be transmitted as 0xFFFF because 0x0000 is a special value meaning no checksum. Substitute 0xFFFF whenever a checksum is computed as zero when modifying a UDP datagram header. Doing this on IPv4 and TCP checksums is unnecessary but legal. Add a wrapper for net_checksum_finish() that makes the substitution. (We can't just change net_checksum_finish(), as that function is also used by receivers to verify checksums, and in that case the expected value is always 0x0000.)

The member VMStateField.start is used for two things, partial data migration for VBUFFER data (basically provide migration for a sub-buffer) and for locating next in QTAILQ. The implementation of the VBUFFER feature is broken when VMSTATE_ALLOC is used. This however goes unnoticed because actually partial migration for VBUFFER is not used at all.

msix_init() reports errors with error_report(), which is wrong when it's used in realize(). The same issue was fixed for msi_init() in commit 1108b2f. In order to make the API change as small as possible, leave the return value check to later patch. For some devices(like e1000e, vmxnet3, nvme) who won't fail because of msix_init's failure, suppress the error report by passing NULL error object. Bonus: add comment for msix_init.

The vmstate_pci_device and vmstate_pcie_devices differ just in the size of one buffer; combine the two using a _TEST macro. I think this is safe as long as everywhere which currently uses either of these two uses the right type.

2016-07-19qapi: Change Netdev into a flat unionEric Blake1-1/+1
This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.

msi_init() reports errors with error_report(), which is wrong when it's used in realize(). Fix by converting it to Error. Fix its callers to handle failure instead of ignoring it. For those callers who don't handle the failure, it might happen: when user want msi on, but he doesn't get what he want because of msi_init fails silently. cc: Gerd Hoffmann <kraxel@redhat.com> cc: John Snow <jsnow@redhat.com> cc: Dmitry Fleytman <dmitry@daynix.com> cc: Jason Wang <jasowang@redhat.com> cc: Michael S.

2016-06-28vmxnet3: Fix reading/writing guest memory specially when behind an IOMMUKarimAllah Ahmed1-89/+108
When a PCI device lives behind an IOMMU, it should use 'pci_dma_*' family of functions when any transfer from/to guest memory is required while 'cpu_physical_memory_*' family of functions completely bypass any MMU/IOMMU in the system. vmxnet3 in some places was using 'cpu_physical_memory_*' family of functions which works fine with the default QEMU setup where IOMMU is not enabled but fails miserably when IOMMU is enabled. This commit converts all such instances in favor of 'pci_dma_*' Cc: Dmitry Fleytman <dmitry@daynix.com> Cc: Jason Wang <jasowang@redhat.com> Cc: qemu-devel@nongnu.org Cc: Anthony Liguori <aliguori@amazon.com> Signed-off-by: KarimAllah Ahmed <karahmed@amazon.de> Acked-by: Dmitry Fleytman <dmitry@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

This patch drops "vmx" prefix from packet abstractions names to emphasize the fact they are generic and not tied to any specific network device.
