bpf_ksock_release(9)

🎀 NAME 🎀

okay bestie, welcome to bpf_ksock_release(9) from the Kernel API Manual — this page is literally about releasing a BPF kernel socket. The name is bpf_ksock_release: release a BPF kernel socket. slay. ✨

🌸 SYNOPSIS 🌸

__bpf_kfunc void bpf_ksock_release (struct bpf_ksock *ks );

that's the whole signature, no cap. 💅

🦋 ARGUMENTS 🦋

• ks — the BPF kernel socket context you're releasing. that's the one, bestie.

💖 DESCRIPTION 💖

so here's the vibe: when the final reference is released, the socket gets cleaned up via queue_rcu_work — and yes, that's because sock_release may sleep. periodt. 🫶

the cleanup is not direct, okay? it goes through queue_rcu_work because sock_release may sleep. that detail is iconic and important. 😭
