STRUCT NETLBL_CALIPSO_OPS(9)

🎀 NAME 🎀

okay bestie, welcome to the struct netlbl_calipso_ops(9) page from the Kernel API Manual 💅 this one is all about the NetLabel CALIPSO ops situation, and it's lowkey iconic.

struct netlbl_calipso_ops — NetLabel CALIPSO operations.

---

🌸 SYNOPSIS 🌸

okay so here's the struct in all its function-pointer glory, no cap:

struct netlbl_calipso_ops {
    int (*doi_add)(struct calipso_doi *doi_def, struct netlbl_audit
*audit_info);
    void (*doi_free)(struct calipso_doi *doi_def);
    int (*doi_remove)(u32 doi, struct netlbl_audit *audit_info);
    struct calipso_doi *(*doi_getdef)(u32 doi);
    void (*doi_putdef)(struct calipso_doi *doi_def);
    int (*doi_walk)(u32 *skip_cnt, int (*callback)(struct calipso_doi
*doi_def, void *arg), void *cb_arg);
    int (*sock_getattr)(struct sock *sk, struct netlbl_lsm_secattr
*secattr);
    int (*sock_setattr)(struct sock *sk, const struct calipso_doi
*doi_def, const struct netlbl_lsm_secattr *secattr);
    void (*sock_delattr)(struct sock *sk);
    int (*req_setattr)(struct request_sock *req, const struct
calipso_doi *doi_def, const struct netlbl_lsm_secattr *secattr);
    void (*req_delattr)(struct request_sock *req);
    int (*opt_getattr)(const unsigned char *calipso, struct
netlbl_lsm_secattr *secattr);
    unsigned char *(*skbuff_optptr)(const struct sk_buff *skb);
    int (*skbuff_setattr)(struct sk_buff *skb, const struct calipso_doi
*doi_def, const struct netlbl_lsm_secattr *secattr);
    int (*skbuff_delattr)(struct sk_buff *skb);
    void (*cache_invalidate)(void);
    int (*cache_add)(const unsigned char *calipso_ptr, const struct
netlbl_lsm_secattr *secattr);
 };

✨ Description ✨

This structure is filled out by the CALIPSO engine and passed to the NetLabel core via a call to netlbl_calipso_ops_register. It enables the CALIPSO engine (and hence IPv6) to be compiled as a module. periodt 💜
