2018-10-19e1000: indicate dropped packets in HW countersJason Wang
The e1000 emulation silently discards RX packets if there's insufficient space in the ring buffer. This leads to errors on higher-level protocols in the guest, with no indication about the error cause. This patch increments the "Missed Packets Count" (MPC) and "Receive No Buffers Count" (RNBC) HW counters in this case. As the emulation has no FIFO for buffering packets that can't immediately be pushed to the guest, these two registers are practically equivalent (see 10.2.7.4, 10.2.7.33 in https://www.intel.com/content/www/us/en/embedded/products/networking/82574l-gbe-controller-datasheet.html). On a Linux guest, the register content will be reflected in the "rx_missed_errors" and "rx_no_buffer_count" stats from "ethtool -S", and in the "missed" stat from "ip -s -s link show", giving at least some hint about the error cause inside the guest. If the cause is known, problems like this can often be avoided easily, by increasing the number of RX descriptors in the guest e1000 driver (e.g under Linux, "e1000.RxDescriptors=1024"). The patch also adds a qemu trace message for this condition. Signed-off-by: Martin Wilck <mwilck@suse.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

2018-09-25hw/net/pcnet-pci: Unify pcnet_ioport_read/write and pcnet_mmio_read/writePeter Maydell
The only difference between our implementation of the pcnet ioport accessors and the mmio accessors is that the former check BCR_DWIO to see what access widths are permitted for addresses in the aprom range (0x0..0xf). In fact our failure to do this in the mmio accessors is a bug (one which was fixed for the ioport accessors in commit 7ba79741970 in 2011). The data sheet for the Am79C970A does not describe the DWIO bit as only applying for I/O space mapped I/O resources and not memory mapped I/O resources, and our MMIO accessors already honour DWIO for accesses in the 0x10..0x1f range (since the pcnet_ioport_{read,write}{w,l} functions check it). The data sheet for the later but compatible Am79C976 is clearer: it states specifically "DWIO mode applies to both I/O- and memory-mapped acceses." This seems to be reasonable evidence in favour of interpretating the Am79C970A spec as being the same. (NB: Linux's pcnet driver only supports I/O accesses, so the MMIO access part of this device is probably untested anyway.)

2018-09-25hw/net/pcnet-pci: Convert away from old_mmio accessorsPeter Maydell
Convert the pcnet-pci device away from using the old_mmio MemoryRegionOps accessor functions. This commit is a no-behaviour-change API conversion. (Since PCNET_PNPMMIO_SIZE is 0x20, the old "addr & 0x10" check and the new "addr < 0x10" check are exact opposites; the new code is phrased to be parallel with the pcnet_io_read/write functions.) I have left a TODO comment marker because the similarity between the MMIO and IO accessor behaviour is suspicious and they could be combined, but this will be left to a different patch.

They can't actually fail, because all they do with the argument is passing it to functions that can't fail: the QObject output visitor, and the @qmp_emit callback, which is either monitor_qapi_event_queue() or event_test_emit(). Drop the argument, and pass &error_abort to the QObject output visitor and @qmp_emit instead.

2018-06-12object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalenceMarc-André Lureau
A link property can be set during creation, with object_property_add_link() and later with object_property_set_link(). add_link() doesn't add a reference to the target object, while set_link() does. Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released. Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG and use that has an indication on how the link handle reference management in set_link().
