The first object is colo-compare. Current colo-compare and net-filters attached on chardev or netdev. It still need more fine-grained network control based on IPFlowSpec. Due to some real user scenarios don't need to monitor all traffic. And qemu net-filter also need function to more detailed flow control. This series give user ability to passthrough kinds of COLO network stream. For example, windows guest user want to enable windows remote desktop to touch guest(UDP/TCP 3389), This case use UDP and TCP mixed, and the tcp part payload always different caused by real desktop display data(for guest time/ mouse display....). Another case is some real user application will actively transmit information include guest time part, primary guest send data with time 10:01.000, At the same time secondary guest send data with time 10:01.001, it will always trigger COLO checkpoint(live migrate) to drop guest performance. V9: - Change the qmp command to passthrough-filter-add/del. - Remove the colo* tag function in net.c. - Fix some comment issues. - Fix some bugs. V8: - Add more comments about QAPI IPFlowSpec. - Fix grammar issue on colo-passthrough-add/delete. - Rebased on upstream. V7: - Keep some data structure stay in .c (patch 4/6). - Fix mutex init issue (patch 5/6). - Make the IPFlowSpec 'protocol' field optional (patch 1/6). - Add compare_passthrough_find function in net.c (patch 6/6). V6: - Change QAPI IPFlowSpec protocol from enum to str. - Use getprotobyname to handle the protocols. - Optimize code in net. V5: - Squash original 1-3 QAPI patches together. - Rename some data structures to avoid misunderstanding. - Reuse InetSocketAddressBase in IPFlowSpec. - Add new function in util/qemu-sockets.c to parse InetSocketAddressBase. - Update HMP command define to reuse current code. - Add more comments. V4: - Fix QAPI code conflict for V6.0 merged patches. - Note this feature for V6.1.
