Hi Geliang,
Thank you for your modifications, that's great!
Our CI did some validations and here is its report:
- KVM Validation: normal: Success! ✅
- KVM Validation: debug: Success! ✅
- KVM Validation: btf-normal (only bpftest_all): Success! ✅
- KVM Validation: btf-debug (only bpftest_all): Success! ✅
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/13697375040
Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/b2ea54bb5a22
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=940967
If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:
$ cd [kernel source code]
$ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
--pull always mptcp/mptcp-upstream-virtme-docker:latest \
auto-normal
For more details:

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)

Thank you for the new version and the changelog! I have some comments, almost there. If you already have patches adding the remaining function pointers to the new mptcp_pm_ops, feel free to add them in the next version. Cheers, Matt
From: Geliang Tang <tanggeliang@kylinos.cn> v10: - drop pm->init in mptcp_pm_validate, move mptcp_pm_validate into a new patch. - remove tlb, use ctl instead in proc_pm_type. - use "strncmp() == 0" instead of "!strncmp()". - set pm_type __MPTCP_PM_TYPE_NR for other names. - add WARN_ON_ONCE in mptcp_pm_unregister. - drop mptcp_userspace_pm_init. - rename "struct mptcp_pm_ops *pm" to "struct mptcp_pm_ops *pm_ops". - drop pm_ops NULL check in mptcp_pm_release. - add struct_group for struct mptcp_pm_data. - move selftests into userspace_pm.sh. v9: - rename mptcp_pm_nl_ prefix to mptcp_pm_kernel_. - rename mptcp_userspace_pm_ prefix to mptcp_pm_userspace_. - update commit logs. v8: - address Matt's comments in v7. v7: - addresss Matt's comments in v6 [1]. - drop "type" from struct mptcp_pm_ops as Matt suggested. - map "pm_type" to new sysctl as Matt suggested. v6: - add "name" in struct mptcp_pm_ops. - add some "sysctl" patches. - drop "struct mptcp_pm_param". - drop "pm_type" in mptcp_pm_data. v5: - use "struct mptcp_pm_param *param" as unified parameters for all interfaces. - register in-kernel mptcp_pm_ops too. - only implement two interfaces "get_local_id" and "get_priority" in this set. v4: - include a new patch "define BPF path manager type". - add new interfaces: created established closed listerner_created listener_closed - rename interfaces as: address_announced address_removed subflow_established subflow_closed get_priority set_priority - rename functions as: mptcp_pm_validate mptcp_pm_register mptcp_pm_unregister mptcp_pm_initialize mptcp_pm_release v3: - rename the 2nd parameter of get_local_id() from 'local' to 'skc'. - keep the 'msk_sport' check in mptcp_userspace_pm_get_local_id(). - return 'err' instead of '0' in userspace_pm_subflow_create(). - drop 'ret' variable inmptcp_pm_data_reset(). - fix typos in commit log. v2: - update get_local_id interface in patch 2. get_addr() and dump_addr() interfaces of BPF userspace pm are dropped as Matt suggested. In order to implement BPF path manager, it's necessary to unify the interfaces of the path manager. This set contains some cleanups and refactoring to unify the interfaces in kernel space. Finally, define a struct mptcp_pm_ops for a path manager.
