💅 fh_verify_local(9) — like, the whole page, bestie

okay so this is a page straight out of the Kernel API Manual and it's about fh_verify_local — filehandle lookup and access checking. yes it's as iconic as it sounds. let's go 🎀

🌸 NAME 🌸

fh_verify_local — filehandle lookup and access checking

literally what it says on the tin, no cap.

✨ SYNOPSIS ✨

__be32 fh_verify_local (struct net *net , struct svc_cred *cred , struct
auth_domain *client , struct svc_fh *fhp , umode_t type , int access );

she takes six arguments and returns a __be32, periodt.

🫶 ARGUMENTS 🫶

  • net — the net namespace where the export lookup is gonna happen 🦋
  • cred — the RPC user credential, aka who's asking
  • client — the RPC auth domain
  • fhp — the filehandle that's getting verified
  • type — the expected type of object that the filehandle points to
  • access — the type of access needed to that object

💖 DESCRIPTION 💖

okay so this API is for callers who don't have an RPC transaction context — like, they are not running in an nfsd thread 🙈. that's the whole vibe check for whether you use this one.

and if you want the full tea on fhp, type, and access? go read fh_verify. she explains it all, iykyk 💅
