Subject: eepro100: Fix network hang when rx buffers run out
This is reported by QA. When installing os with pxe, after the initial
kernel and initrd are loaded, the procedure tries to copy files from install
server to local harddisk, the network becomes stall because of running out of
receive descriptor.
[Whitespace fixes and removed qemu_notify_event() because Paolo's
earlier net patches have moved it into qemu_flush_queued_packets().
Additional info:
I can reproduce the network hang with a tap device doing a iPXE HTTP
boot as follows:
$ qemu -enable-kvm -m 1024 \
-netdev tap,id=netdev0,script=no,downscript=no \
-device i82559er,netdev=netdev0,romfile=80861209.rom \
-drive if=virtio,cache=none,file=test.img
iPXE> ifopen net0
iPXE> config # set static network configuration
iPXE> kernel
http://mirror.bytemark.co.uk/fedora/linux/releases/17/Fedora/x86_64/os/images/pxeboot/vmlinuz
I needed a vanilla iPXE ROM to get to the iPXE prompt. I think the boot
prompt has been disabled in the ROMs that ship with QEMU to reduce boot
time.
During the vmlinuz HTTP download there is a network hang. hw/eepro100.c
has reached the end of the rx descriptor list. When the iPXE driver
replenishes the rx descriptor list we don't kick the QEMU net subsystem
and event loop, thereby leaving the tap netdev without its file
descriptor in select(2).

Changes:
qemu (1.1.2+dfsg-3) unstable; urgency=low
.
* add build-dependency on libcap-dev [linux-any] to enable virtfs support
which has been dropped in 1.1. (Closes: #677654)
*
intel_hda-do-not-call-msi_reset-when-only-device-state-needs-resetting.patch
patch to fix Fixing reset of MSI function in intel-hda virtual device.
The fix (applied to stable-1.1.1) was partially wrong, as it actually
added the msi_reset() call to two code paths instead of one as planned.
Fix this by splitting the function in question into two parts.
(Closes: #688964)
* blockdev-preserve-readonly-and-snapshot-states-across-media-changes.patch:
allow opening of read-only cdrom images/devices (Closes: #686776)
* ahci-properly-reset-PxCMD-on-HBA-reset.patch: fix windows install on ahci
(Closes: #696052)
* e1000-discard-packets-that-are-too-long-if-not-SBP-and-not-LPE.patch:
discard too long rx packets which may overflow guest buffer
(Closes: #696051)
* eepro100-fix-network-hang-when-rx-buffers-run-out.patch:
fix e100 stall (Closes: #696061)
* fix possible network stalls/slowness in e1000 device emulation:
net-notify-iothread-after-flushing-queue.patch
e1000-flush-queue-whenever-can_receive-can-go-from-false-to-true.patch
(Closes: #696063)
* fixes-related-to-processing-of-qemu-s-numa-option.patch:
fixes numa handling (Closes: #691343)
* qcow2-fix-avail_sectors-in-cluster-allocation-code.patch:
fixes data corruption in stacked qcow2 (Closes: #695905)
* qcow2-fix-refcount-table-size-calculation.patch: another possible
corruption or crash in qcow2 (Closes: #691569)
* tap-reset-vnet-header-size-on-open.patch: always ensure tap device is
in known state initially (Closes: #696057)
* vmdk-fix-data-corruption-bug-in-WRITE-and-READ-handling.patch:
possible data corruption bug in vmdk image format (Closes: #696050)
