bpf_crypto_ctx_release(9)

💅 bpf_crypto_ctx_release — a.k.a. the "bestie, you're done here" page 🎀

okay so real talk, this is bpf_crypto_ctx_release, and it lives in section 9 of the Kernel API Manual. she's short, she's sweet, she's giving cleanup era, and honestly? we stan a function that knows how to say goodbye. 🦋

✨ NAME ✨

bpf_crypto_ctx_release — drop a reference to a BPF crypto context you grabbed earlier. that's it, that's the whole vibe. 💜

---

🌸 SYNOPSIS 🌸

__bpf_kfunc void bpf_crypto_ctx_release (struct bpf_crypto_ctx *ctx );

like, <rainbow>exactly</rainbow> that. no extra args, no sneaky little surprises, just the one pointer and a dream. ✨

🫶 ARGUMENTS 🫶

• ctx — the crypto context you're releasing. yes, that one. the one you're done with. say bye bestie 👋

---

🔥 DESCRIPTION 🔥

so here's the tea ☕: this drops a reference to a BPF crypto context that you previously acquired. lowkey the most important part — when the final reference to that BPF crypto context gets released, its memory will be released too. like, the last one out turns off the lights. 💡😭

that's it. no cap, that's the entire bit. release responsibly, and the cleanup handles itself. 💅

fr fr: this is the paired "i'm done with you" move to bpf_crypto_ctx_acquire(9) — and the final release is when the memory actually goes. so don't be out here releasing things you never acquired, iykyk 🙈
