PROBE::NFSD.CREATEV3(3stap)

💅 PROBE::NFSD.CREATEV3 💅

okay bestie, welcome to the SystemTap Tapset Reference corner of the internet, manual page PROBE::NFSD.CREATEV3(3stap) — Network File Storage Tapsets edition, and yes she's from 3stap, we love that for her 🫶

---

✨ NAME ✨

probe::nfsd.createv3 — the NFS server is out here creating a regular file, or setting file attributes for a client. very main character behaviour, honestly 🌸

---

🦋 SYNOPSIS 🦋

probe nfsd.createv3 {}

periodt. that's the whole vibe check. 💅

---

🎀 VALUES 🎀

these are the little goodies you get to peek at, one by one, no skipping, we're doing all of them 🍓

• filename — the file name. literally just the name of the file, iconic.
• filelen — the length of filename. yes she has a size and we're respecting it.
• client_ip — the ip address of the client. who's knocking at the door? 👀
• verifier — file attributes (atime,mtime,mode). she's used to reset file attributes for CREATE_EXCLUSIVE. no cap.
• createmode — the create mode. the possible values could be: NFS3_CREATE_EXCLUSIVE, NFS3_CREATE_UNCHECKED, or NFS3_CREATE_GUARDED. three options, pick your fighter ✨
• truncp — trunp arguments, indicates if the file shouldbe truncate. (yes, that's exactly how it's spelled in the original, I am NOT touching it, that's her name now 💀)
• fh — file handle (the first part is the length of the file handle). lowkey important, she's the whole point.
• iap_valid — Attribute flags.
• iap_mode — file access mode.

---

🌈 DESCRIPTION 🌈

This probepoints is only called by nfsd3_proc_create and nfsd4_open when op_claim_type is NFS4_OPEN_CLAIM_NULL.

so like. if you were wondering when this probe shows up — it's those two, and only when that claim type hits. iykyk 👑
