__fh_verify(9)

📦 version 7.3.1, in nixpkgs unstable

💅 __fh_verify — like, the manual page, bestie

okay so this is a page straight out of the Kernel API Manual, section 9 (kernel developer vibes only, no cap) — it's all about __fh_verify, which does filehandle lookup and access checking in one iconic little move. putting this here so you actually get it 🫶

✨ NAME ✨

__fh_verify — filehandle lookup and access checking

like yes, that's the whole name, and yes, it's doing two jobs at once. main character energy fr.

🌸 SYNOPSIS 🌸

__be32 __fh_verify (struct svc_rqst *rqstp , struct net *net , struct
svc_cred *cred , struct auth_domain *client , struct auth_domain
*gssclient , struct svc_fh *fhp , umode_t type , int access );

not me counting the args — there are eight, and it hands you back a __be32. so many parameters, so little time 💀

🎀 ARGUMENTS 🎀

  • rqstp — the RPC transaction context, or NULL. yes bestie, NULL is a legal move here.
  • net — the net namespace where the export lookup happens. this is where we're looking, okurr.
  • cred — the RPC user credential. who even are you, allegedly.
  • client — the RPC auth domain.
  • gssclient — the RPC GSS auth domain, or NULL. another NULL-friendly one, we love consistency 💖
  • fhp — the filehandle that's getting verified. the star of the show, lowkey.
  • type — the expected type of the object that the filehandle points to. gotta know what we're looking at.
  • access — the type of access you need to that object. what are we even allowed to do here.

🦋 DESCRIPTION 🦋

so the actual description is short and sweet: see fh_verify for further descriptions of fhp, type, and access. that's it. that's the whole bit. it's giving "go read the other page, i'm not repeating myself" 🙈

no seriously — that's the entire DESCRIPTION section, and i'm not about to invent lore that isn't there. go read fh_verify(9) if you want the deep dive on fhp, type, and access. iykyk.

⭐ SEE ALSO ⭐

Kernel file ./fs/nfsd/nfsfh.c — and also these absolute legends:

the whole nfsd filehandle friend group, honestly. obsessed 🔥

quick vibe check: the page only says "see fh_verify" for fhp, type, and access — it does not spell anything else out here, so don't come for me if you wanted more. that's genuinely all the source gave us 💀

and that's the page, bestie!! 🌈 from ./fs/nfsd, dated October 2026, tagged __fh_verify(9) — slay, go verify some filehandles, periodt 💅✨
