In order to implement BPF userspace path manager, it is necessary to unify the interfaces of the path manager. This set contains some cleanups for unify the interfaces. struct mptcp_pm_ops { int (*address_announce)(struct mptcp_sock *msk, struct mptcp_pm_addr_entry *local); int (*address_remove)(struct mptcp_sock *msk, u8 id); int (*subflow_create)(struct mptcp_sock *msk, struct mptcp_pm_addr_entry *local, struct mptcp_addr_info *remote); int (*subflow_destroy)(struct mptcp_sock *msk, struct mptcp_pm_addr_entry *local, struct mptcp_addr_info *remote); int (*get_local_id)(struct mptcp_sock *msk, struct mptcp_pm_addr_entry *local); u8 (*get_flags)(struct mptcp_sock *msk, struct mptcp_addr_info *skc); struct mptcp_pm_addr_entry *(*get_addr)(struct mptcp_sock *msk, u8 id); int (*dump_addr)(struct mptcp_sock *msk, struct mptcp_id_bitmap *bitmap); int (*set_flags)(struct mptcp_sock *msk, struct mptcp_pm_addr_entry *local, struct mptcp_addr_info *remote); u8 type; struct module *owner; struct list_head list; void (*init)(struct mptcp_sock *msk); void (*release)(struct mptcp_sock *msk); } ____cacheline_aligned_in_smp; Geliang Tang (11): mptcp: add struct mptcp_id_bitmap mptcp: add mptcp_userspace_pm_get_sock helper mptcp: use __lookup_addr in pm_netlink mptcp: add mptcp_for_each_address macros mptcp: use sock_kfree_s instead of kfree mptcp: add lookup_addr for userspace pm mptcp: change remote as mptcp_addr_info mptcp: change local as mptcp_pm_addr_entry mptcp: make three pm wrappers static mptcp: drop skb parameter of get_addr mptcp: drop skb parameter of set_flags net/mptcp/pm.c | 25 +--- net/mptcp/pm_netlink.c | 99 +++++++++------- net/mptcp/pm_userspace.c | 250 ++++++++++++++++----------------------- net/mptcp/protocol.h | 23 ++-- 4 files changed, 171 insertions(+), 226 deletions(-)
