Subject: [Qemu-devel] [RFC PATCH V7 0/7] Introduce COLO-compare
Date: Mon, 18 Jul 2016 14:20:56 +0800 [thread overview]
Message-ID: <1468822860-25979-1-git-send-email-zhangchen.fnst@cn.fujitsu.com> (raw)
COLO-compare is a part of COLO project. It is used
to compare the network package to help COLO decide

The full version in this github:
https://github.com/zhangckid/qemu/tree/colo-v2.7-proxy-mode-compare-with-colo-base-jul18
v7:
p5:
- add [PATCH]qemu-char: Fix context for g_source_attach()
in this patch series.
v6:
p6:
- add more commit log.
- fix icmp comparison to compare all packet.
p5:
- add more cpmments in commit log.
- change REGULAR_CHECK_MS to REGULAR_PACKET_CHECK_MS
- make check old packet independent to compare thread
- remove thread_status
p4:
- change this patch only about
Connection and ConnectionKey.
- add some comments in commit log.
- remove mode in fill_connection_key().
- fix some comments and bug.
- move colo_conn_state to patch of
"work with colo-frame"
- remove conn_list_lock.
- add MAX_QUEUE_SIZE, if primary_list or
secondary_list biger than MAX_QUEUE_SIZE
we will drop packet.
p3:
- add new independent kernel jhash patch.
p2:
- add new independent colo-base patch.
p1:
- add a ascii figure and some comments to explain it
- move trace.h to p2
- move QTAILQ_HEAD(, CompareState) net_compares to
patch of "work with colo-frame"
- add some comments in qemu-option.hx
v5:
p3:
- comments from Jason
we poll and handle chardev in comapre thread,
Through this way, there's no need for extra
synchronization with main loop
this depend on another patch:
qemu-char: Fix context for g_source_attach()
- remove QemuEvent
p2:
- remove conn->list_lock
p1:
- move compare_pri/sec_chr_in to p3
- move compare_chr_send to p2
v4:
p4:
- add some comments
- fix some trace-events
- fix tcp compare error
p3:
- add rcu_read_lock().
- fix trace name
- fix jason's other comments
- rebase some Dave's branch function
p2:
- colo_compare_connection() change g_queue_push_head() to
- g_queue_push_tail() match to sorted order.
- remove pkt->s
- move data structure to colo-base.h
- add colo-base.c reuse codes for filter-rewriter
- add some filter-rewriter needs struct
- depends on previous SocketReadState patch
p1:
- except move qemu_chr_add_handlers()
to colo thread
- remove class_finalize
- remove secondary arp codes
- depends on previous SocketReadState patch
v3:
- rebase colo-compare to colo-frame v2.7
- fix most of Dave's comments
(except RCU)
- add TCP,UDP,ICMP and other packet comparison

- add some comments
- other bug fix
- add RFC index
- add usage in patch 1/4
v2:
- add jhash.h
v1:
- initial patch
Zhang Chen (7):
colo-compare: introduce colo compare initialization
colo-base: add colo-base to define and handle packet
Jhash: add linux kernel jhashtable in qemu
colo-compare: track connection and enqueue packet
qemu-char: Fix context for g_source_attach()
