BPF path manager, part 1
|
expand
|
From: Geliang Tang <tanggeliang@kylinos.cn> In order to implement BPF userspace path manager, it is 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 userspace path manager like this: 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; The BPF-related code will be sent in the next set part 2.
