Subject: [PATCH v8 0/4] mptcp: fix conflicts when using pm.add_signal in ADD_ADDR/echo and RM_ADDR process
Date: Thu,  8 Jul 2021 01:01:37 +0800	[thread overview]
Message-ID: <1625677301-139357-1-git-send-email-liyonglong@chinatelecom.cn> (raw)

fix issue: ADD_ADDR and RM_ADDR use pm.add_signal to mark event, so 
in some case pm.add_signal will be flush when ADD_ADDR/RM_ADDR in 
process.

fix issue: if ADD_ADDR and ADD_ADDR-echo process at the same time, 
only one event can write pm.add_signal. so ADD_ADDR will process 
after add_timer timeout or ADD_ADDR-echo will not be process.

Patch 1 fix ADD_ADDR and RM_ADDR maybe clear addr_signal each other.

Patch 2 and 3 deal ADD_ADDR and ADD_ADDR-echo with separately to fix 
conflicts in using pm.addr_signal porcess.

Patch 4 MPTCP_ADD_ADDR_IPV6 and MPTCP_ADD_ADDR_PORT is not necessary.

v1->v2:
 - remove READ_ONCE under the pm spin lock.

v2->v3:
 - Patch 2: mptcp_pm_should_add_addr => mptcp_pm_should_add_signal_addr
 - Patch 3: avoid read-modify-write of msk->pm.addr_signal and change  
   mptcp_pm_add_addr_signal to return void.

v3->v4:
 - Patch 1: use ~(BIT(MPTCP_ADD_ADDR_SIGNAL) | BIT(MPTCP_ADD_ADDR_ECHO)) 
   instead of BIT(MPTCP_RM_ADDR_SIGNAL)
 - Patch 3: simple the code; init flags; fix wrong goto logic code; 

v4->v5:
 - Patch 3: simple the code of 'mptcp_established_options_add_addr'

v5->v6:
 - Patch2: fix fails of 'mptcp_join.sh -t'. In mptcp_pm_add_addr_send_ack 
   without MPTCP_ADD_ADDR_SIGNAL check so pure ack can not be sent for 
   ADD_ADDR. That cause ADD_ADDR can not be sent in time.
 - Patch3: refactor some code according Geliang's suggestions.
 - Patch4: modify commit comment

v6->v7:
 - Patch1: use reverse xmas tree order for variables definition
 - Patch3: refactor some code according Geliang's suggestions.
 - add a Patch4: remove some double-check

v7->v8:
 - Patch1,2: exchange patch1 and patch2 
 - Patch3: refactor some code according Geliang's suggestions.
 - remove patch "remove some double check", Geliang think it's unnecessary

Yonglong Li (4):
  mptcp: make MPTCP_ADD_ADDR_SIGNAL and MPTCP_ADD_ADDR_ECHO separate
  mptcp: fix ADD_ADDR and RM_ADDR maybe flush addr_signal each other
  mptcp: build ADD_ADDR/echo-ADD_ADDR option according pm.add_signal
  mptcp: remove MPTCP_ADD_ADDR_IPV6 and MPTCP_ADD_ADDR_PORT
