💅 nlmsvc_proc_share — the Kernel API Manual page, bestie edition ✨

okay so real talk, this is a page from the Kernel API Manual and the star of the show is nlmsvc_proc_share(9) — the NLM server proc that handles the SHARE procedure. she's lowkey the moment, ngl 🎀

✨ NAME ✨

nlmsvc_proc_share — SHARE: open a file using DOS file-sharing modes 🦋

like, yes, DOS modes, in the kernel, in the year of our lord. it's giving legacy but make it iconic 💅

🌸 SYNOPSIS 🌸

__be32 nlmsvc_proc_share (struct svc_rqst *rqstp );

that's the whole signature, she's compact and she knows it ✨

💖 ARGUMENTS 💖

  • rqstp — the RPC transaction context. basically the little backpack this call carries all its RPC info around in 🎒

🫶 RETURN 🫶

  • rpc_success — the RPC executed successfully. slay, it worked 👑
  • rpc_drop_reply — do not send an RPC reply. like, just don't reply. ghosting, but intentional 💀

🔥 DESCRIPTION 🔥

okay so here's the RPC synopsis, hold my iced coffee:

nlm_shareres NLM_SHARE(nlm_shareargs) = 20;

that 20 is the procedure number, don't @ me, it's just what it is 🍓

now the permissible procedure status codes — the vibe check results, if you will:

  • LCK_GRANTED — the requested share lock was granted. we love a win 💖
  • LCK_DENIED — the requested lock conflicted with existing lock reservations for the file. awkward. someone else got there first 😭
  • LCK_DENIED_GRACE_PERIOD — the server has recently restarted and is re-establishing existing locks, and is not yet ready to accept normal service requests. she's healing, give her a minute 🧚

and the Linux NLM server implementation also returns this extra one, very spicy, very Linux of her:

  • LCK_DENIED_NOLOCKS — a needed resource could not be allocated. out of resources, no cap 🫠
