Posted by Geliang Tang 7 months, 1 week ago

From: Geliang Tang <tanggeliang@kylinos.cn>

v7:
 - drop 'mask' variable, use MPTCP_PM_WORK_MASK instead.
 - add 'status' parameter for __mptcp_pm_kernel_worker.
 - no longer renamed, keep the names of mptcp_pm_addr_send_ack and
   mptcp_pm_create_subflow_or_signal_addr unchanged.

v6:
 - squash accept_new_subflow patches into one.
 - change "pm->subflows == subflows_max - 1" to
	pm->subflows + 1 == subflows_max.
 - not to call accept_new_subflow under the PM lock.
 - add mptcp_pm_accept_subflow helpers.
 - drop READ_ONCE in mptcp_pm_worker.
 - clear all the pm status flags once in mptcp_pm_worker.
 - https://patchwork.kernel.org/project/mptcp/cover/cover.1743133948.git.tanggeliang@kylinos.cn/

v5:
 - add comment "call from the subflow/msk context" for mptcp_sched_ops.
 - add new helper mptcp_pm_accept_new_subflow.
 - add "bool allow" parameter for mptcp_pm_accept_new_subflow, and drop
   .allow_new_subflow interface.
 - use a copy of pm->status in mptcp_pm_worker.
 - rename mptcp_pm_create_subflow_or_signal_addr with "__" prefix.
 - drop "!update_subflows" in mptcp_pm_subflow_check_next.
 - add_addr_received/rm_addr_received interfaces will be added in the
   next series.

v4:
 - address Matt's comments in v3. 
 - update pm locks in mptcp_pm_worker.
 - move the lock inside mptcp_pm_create_subflow_or_signal_addr.
 - move the lock inside mptcp_pm_nl_add_addr_received.
 - invoke add_addr_received interface from mptcp_pm_worker.
 - invoke rm_addr_received interface from mptcp_pm_rm_addr_or_subflow.
 - simply call mptcp_pm_close_subflow() in mptcp_pm_subflow_check_next.
 - https://patchwork.kernel.org/project/mptcp/cover/cover.1742804266.git.tanggeliang@kylinos.cn/

v3:
 - merge 'bugfixes for "BPF path manager, part 6, v2"' into this set.
 - https://patchwork.kernel.org/project/mptcp/cover/cover.1742521397.git.tanggeliang@kylinos.cn/

v2:
 - address Matt's comments in v1. 
 - add add_addr_received and rm_addr_received interfaces.
 - drop subflow_check_next interface.
 - add a "required" or "optional" comment for a group of interfaces in
   struct mptcp_pm_ops.

v1:
- https://patchwork.kernel.org/project/mptcp/cover/cover.1741685260.git.tanggeliang@kylinos.cn/

New interfaces for struct mptcp_pm_ops.
