Hi~ all~~
Anyone have some comments for this series?
Will have a look at this.
Btw. I wonder how this is tested, do we need a unit test for this?
We need more comments to improve COLO codes.
Thanks

Filter-rewriter is a part of COLO project.
So this patch set depend on colo-compare.
Interesting, I thought it can co-work with comparing, and the
communication were done through socket now. So I think technically the
filter itself could work without COLO?
It will rewrite some of secondary packet to make
secondary guest's connection established successfully.
In this module we will rewrite tcp packet's ack to the secondary
from primary,and rewrite tcp packet's seq to the primary from
secondary.
v3:
- fix typo
- add conn->syn_flag
- add some comments
- remove conn_list_lock
- fix offset set bug
I think you can remove RFC in the next version so we can try to merge it
after one or several other iterations.
Thanks
v2:
- add more comments about packet flows
- add some trace-event
- add seq offset ( = secondary_seq - primary_seq)
v1:
- initial patch
Zhang Chen (3):
filter-rewriter: introduce filter-rewriter initialization
filter-rewriter: track connection and parse packet
filter-rewriter: rewrite tcp packet to keep secondary connection
