STRUCT OVPN_CB(9)

✨ struct ovpn_cb — the ovpn skb control block, bestie 💅

okay so this is a page from the Kernel API Manual, and honestly? it's a little icon and it deserves your attention. we're talking about struct ovpn_cb, which is the ovpn skb control block. that's the vibe. no cap. 🦋

✨ NAME ✨

struct ovpn_cb — the ovpn skb control block. that's it, that's the name, and it ate. 👑

---

🌸 SYNOPSIS 🌸

here's the whole struct, character for character, don't touch it:

struct ovpn_cb {
    struct ovpn_peer *peer;
    struct ovpn_crypto_key_slot *ks;
    void *crypto_tmp;
    unsigned int payload_offset;
    bool nosignal;
 };

literally every member, all five of them, living their best life in there. 🫶

🎀 Members 🎀

okay so let's meet the cast, main character energy only:

• peer — the peer this skb was received from or sent to. your buddy. your person. 🌈
• ks — the crypto key slot used to encrypt/decrypt this skb. the keys to the kingdom, fr fr. 🔥
• crypto_tmp — pointer to temporary memory used for crypto operations, and that memory contains the IV, the scatter gather list and the aead request. three things, one pointer, we love a multitasker. 😭
• payload_offset — offset in the skb where the payload starts. like, that's where the actual stuff begins, iykyk. ⭐
• nosignal — whether this skb should be sent with the MSG_NOSIGNAL flag (TCP). yes, that exact flag, yes, TCP, we said what we said. 💀

ngl bestie, that's the whole struct. no sneaky extra fields, no secret defaults, nothing hiding in the back. what you see is what you get, periodt. 💜

go look at the kernel file ./drivers/net/ovpn/skb.h — that's the one, that's the source of truth, go be obsessed with it. 🧚

and that's the page! this one came from ./drivers/net/ovpn, dated October 2026, and it's struct ovpn_cb(9) — stay iconic, stay caffeinated, and go read your headers. 💖✨🎀
