svcauth_null_accept(9)

💖 svcauth_null_accept — the Kernel API Manual moment 🦋

okay so bestie, welcome to the glow-up of svcauth_null_accept(9), straight out of the Kernel API Manual. no cap, this one is a whole vibe check for incoming RPC creds ✨

---

🌸 NAME 🌸

svcauth_null_accept — the function that decodes and validates an incoming RPC_AUTH_NULL credential, and honestly? she's doing both jobs and she's serving 💅

---

🎀 SYNOPSIS 🎀

enum svc_auth_status svcauth_null_accept (struct svc_rqst *rqstp );

like, that's the whole signature. iconic. not me memorising it fr fr 🫶

---

✨ ARGUMENTS ✨

• rqstp — the RPC transaction. that's your main character right there, she carries the whole scene 💜

---

💀 DESCRIPTION 💀

so here's the tea, bestie — these are the return values, and you gotta know all of them:

• SVC_OK: both the credential and the verifier are valid. slay, we love a clean pass 🌈
• SVC_DENIED: the credential or the verifier is not valid. nope, not today 🙈
• SVC_GARBAGE: it failed to decode the credential or the verifier. literally unusable 😭
• SVC_CLOSE: temporary failure. not a forever thing, just a moment 💀

also, rqstp->rq_auth_stat gets set, as mandated by RFC 5531. that's not optional, that's the rules, periodt 👑

like, for real — rq_auth_stat is set exactly as RFC 5531 mandates. no improvising, no vibes-based auth, iykyk.

lowkey a warning bestie: the return values mean completely different things — SVC_OK is not the same as SVC_DENIED, and SVC_GARBAGE is not SVC_CLOSE. don't mix them up, that's a bad timeline 💅

and that's the page! mwah 💋
