Coverity complains about two overruns in process_tx_desc(). The complaints are false positives, but we might as well eliminate them. The problem is that "hdr" is defined as an unsigned int, but then used to offset an array of size 65536, and another of size 256 bytes. hdr will actually never be greater than 255 though, as it's assigned only once and to the value of tp->hdr_len, which is an uint8_t. This patch simply gets rid of hdr, replacing it with tp->hdr_len, which makes it consistent with all other tp member use in the function. v2: - also cleanup coding style issues in the touched lines Signed-off-by: NAndrew Jones <drjones@redhat.com> Signed-off-by: NMichael S.

All PCI nics are switched to EFI-enabled roms by default. They are composed from three images (legacy, efi ia32 & efi x86), so classic pxe booting will continue to work. Exception: eepro100 is not switched, it uses a single rom for all emulated eepro100 variants, then goes patch the rom header on the fly with the correct PCI IDs. I doubt that will work as-is with the efi roms. Keep old roms for 1.4+older machine types via compat properties, needed because the efi-enabled roms are larger so the pci rom bar size would change.

Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

Fixes a couple of regression bugs introduced by b9d03e35 and related to auto-negotiation: - Auto-negotiation currently sets link up even if it was forced down from the monitor. - If Auto-negotiation was in progress during migration, link will never come up.

This reverts commit 84dd2120. I'm not sure what issue the original commit was meant to fix, or if the logic is actually wrong, but it causes e1000 to stop working after a guest issues a reset. >From what I can tell a guest with an e1000 nic has no way of changing the link status, as far as it's NetClient peer is concerned, except in the auto-negotiation path, so with this patch in place there's no recovery after a reset, since the link goes down and stays that way.

Since 39bffca2 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

Some guest operating systems' drivers (Mac OS X in particular) fail to properly initialize the Receive Address registers (probably expecting them to be pre-initialized by an earlier component, such as a specific proprietary BIOS). This patch pre-initializes the RA registers, allowing OS X networking to function properly. Other guest operating systems are not affected, and free to (re)initialize these registers during boot. [According to the datasheet the Address Valid bits in the RA registers are cleared on PCI or software reset. This patch adds the NIC's MAC address and sets Address Valid on reset. So we diverge from real hardware behavior here. -- Stefan] Signed-off-by: NGabriel Somlo <somlo@cmu.edu> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

Indeed, there's nothing else except for the time spent on the negotiation needs to be emulated. This is needed for resuming windows guest from hibernation, as without a proper delay, qemu would send the packet too early ( guest even does not have a proper intr handler), which could lead windows guest hang. This patch first introduces an array of function pointers to make it possible to emulate per-register write behavior. Then traps the PHY_CTRL register write and when guest want to restart the link auto negotiation, we would down the link and mark the auto negotiation in progress in PHY_STATUS register. After time, a timer with 500 ms ( which is the minimum timeout of auto-negotation specified in 802.3 spec). The link would be up when timer expired. Test with resuming windows guest plus flood ping and linux ethtool linkstatus test. Signed-off-by: NJason Wang <jasowang@redhat.com> Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>
