2016-05-25net: mipsnet: check packet length against bufferPrasad J Pandit
When receiving packets over MIPSnet network device, it uses receive buffer of size 1514 bytes. In case the controller accepts large(MTU) packets, it could lead to memory corruption. Add check to avoid it. Reported by: Oleksandr Bazhaniuk <oleksandr.bazhaniuk@intel.com> Signed-off-by: Prasad J Pandit <pjp@fedoraproject.org> Signed-off-by: Jason Wang <jasowang@redhat.com>

Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-19-git-send-email-peter.maydell@linaro.org
2015-07-27mipsnet: Flush queued packets when receiving is enabledFam Zheng
Drop .can_receive and move the semantics to mipsnet_receive, by returning 0. After 0 is returned, we must flush the queue explicitly to restart it: Call qemu_flush_queued_packets when s->busy or s->rx_count is being updated.

2015-01-12net: remove all cleanup methods from NIC NetClientInfosPaolo Bonzini
All NICs have a cleanup function that, in most cases, zeroes the pointer to the NICState. In some cases, it frees data belonging to the NIC. However, this function is never called except when exiting from QEMU. It is not necessary to NULL pointers and free data here; the right place to do that would be in the device's unrealize function, after calling qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue devices. This cleanup function gets in the way of making the NetClientStates for the NIC hold an object_ref reference to the object, so get rid of it.

2014-05-14savevm: Remove all the unneeded version_minimum_id_old (rest)Juan Quintela
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.
