ksmbd_decompress_request(9)

✨ NAME ✨

ksmbd_decompress_request — replace a compressed request with its SMB2 PDU. This page is from the Kernel API Manual, bestie 💖

🎀 SYNOPSIS 🎀

int ksmbd_decompress_request (struct ksmbd_conn *conn );

🦋 ARGUMENTS 🦋

• conn — the connection that owns the current RFC1002 request buffer, periodt 🫶

🌸 DESCRIPTION 🌸

Okay so here’s the vibe: this function takes a compressed request and gives it the full main-character glow-up into its SMB2 PDU form ✨

It derives the uncompressed size from the transform variant, enforces ksmbd’s normal message limits, and asks the common decoder to validate every payload. No skipping the vibe check, ngl 💅

On success, it replaces conn->request_buf with a regular RFC1002-framed SMB2 message. The way that works means the rest of the request path needs no compression awareness at all 😌 iconic behavior, honestly.

💜 RETURN 💜

0 on success, otherwise a negative errno. That’s it, that’s the tea 🍓
