handshake_req_cancel(9)

💅 handshake_req_cancel(9) 💅

okay so this is a Kernel API Manual page, and the function is handshake_req_cancel() — say it with me, bestie 💖

✨ NAME ✨

handshake_req_cancel — cancel an in-progress handshake. literally what it says on the tin 🫶

🌸 SYNOPSIS 🌸

bool handshake_req_cancel (struct sock *sk );

🎀 ARGUMENTS 🎀

• sk — the socket on which there is an ongoing handshake. that’s the target, no cap 💅

🦋 DESCRIPTION 🦋

So here’s the tea: request cancellation races with request completion. 😭 like, both things can be happening at the same time, and you don’t get to just assume who got there first. To determine who won, callers examine the return value from this function. that’s the vibe check right there ✨

Return values:

• true — an uncompleted handshake request was canceled. slay, it got canceled before it finished 💖
• false — the handshake request was already completed, or it was not found. so either it already finished, or it’s just not there 💀

🌈 SEE ALSO 🌈

• Kernel file ./net/handshake/request.c
• handshake_req_alloc(9)
• handshake_req_private(9)
• handshake_req_next(9)
