Hi Jason,
Please help me merge the COLO proxy patch to net branch.
Thanks
Chen
Rao, Lei (7):
Remove some duplicate trace code.
Fix the qemu crash when guest shutdown during checkpoint
Optimize the function of filter_send
Remove migrate_set_block_enabled in checkpoint
Add a function named packet_new_nocopy for COLO.
Add the function of colo_compare_cleanup
Fixed calculation error of pkt->header_size in fill_pkt_tcp_info()

is enabled in COLO mode, we can directly report an error.and there
is no need to disable block migration at every checkpoint.

Use the packet_new_nocopy instead of packet_new in the

When chardev is cleaned up, chr_write_lock needs to be destroyed. But
the colo-compare module is not cleaned up normally before it when the
guest poweroff. It is holding chr_write_lock at this time. This will
cause qemu crash.So we add the function of colo_compare_cleanup() before
qemu_chr_cleanup() to fix the bug.

The data pointer has skipped vnet_hdr_len in the function of
parse_packet_early().So, we can not subtract vnet_hdr_len again
when calculating pkt->header_size in fill_pkt_tcp_info(). Otherwise,
it will cause network packet comparsion errors and greatly increase
the frequency of checkpoints.
