[PATCH V7 0/6] Passthrough specific network traffic in COLO |

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.
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.
V3:
- Add COLO passthrough list lock.
- Add usage demo and more comments.
V2:
- Add the n-tuple support.
- Add some qapi definitions.
- Support multi colo-compare objects.
- Support setup each rules for each objects individually.
- Clean up COLO compare definition to .h file.
- Rebase HMP command for stable tree.
- Add redundant rules check.
Zhang Chen (6):
qapi/net: Add IPFlowSpec and QMP command for COLO passthrough
util/qemu-sockets.c: Add inet_parse_base to handle
InetSocketAddressBase
hmp-commands: Add new HMP command for COLO passthrough
net/colo-compare: Move data structure and define to .h file.
net/colo-compare: Add passthrough list to CompareState
net/net.c: Add handler for COLO passthrough connection
