🌈 smb311_update_preauth_hash(9) — Kernel API Manual 🌈

💖 NAME 💖

smb311_update_preauth_hash — update @ses hash with the packet data in @iov ✨

🎀 SYNOPSIS 🎀

void smb311_update_preauth_hash (struct cifs_ses *ses , struct
       TCP_Server_Info *server , struct kvec *iov , int nvec );

🦋 ARGUMENTS 🦋

  • ses — server session structure, aka the session's little ID card 🪪
  • server — pointer to server info, the server's vibes dossier 👀
  • iov — array containing the SMB request we will send to the server 📦
  • nvec — number of array entries for the iov 🔢

🌸 DESCRIPTION 🌸

Okay so the whole vibe check here is very specific: this function assumes iov does not contain the rfc1002 length, and that iov[0] has the SMB2 header. That's the assumption, bestie — it's giving "the layout is already handled, don't worry about it" energy 💅

No cap, that's the description. Short, sweet, and very particular about its iovec setup 🫶
