πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ksmbd_decode_ntlmssp_auth_blob πŸ’…

okay so this is a page straight out of the Kernel API Manual β€” section 9, tiny little corner of the kernel docs β€” and honestly? it's giving niche but iconic. it's all about decoding an NTLMSSP authenticate blob in ksmbd, and yes we're gonna get through it together, bestie 🫢


✨ NAME ✨

ksmbd_decode_ntlmssp_auth_blob β€” a helper function that constructs the authenticate blob. literally that's the whole job. no cap πŸ’…


πŸ¦‹ SYNOPSIS πŸ¦‹

int ksmbd_decode_ntlmssp_auth_blob (struct authenticate_message
*authblob , int blob_len , struct ksmbd_conn *conn , struct
ksmbd_session *sess , char *sess_key );

so she's an int-returning girly with five params, and we're gonna meet every single one of them right now ⬇️


πŸŽ€ ARGUMENTS πŸŽ€

  • authblob β€” it's a struct authenticate_message *, and it's the source pointer for the authenticate blob. like, this is where the blob lives. main character energy fr ✨
  • blob_len β€” an int, and it's the length of the authblob message. gotta know how big the vibe is πŸ’«
  • conn β€” a struct ksmbd_conn *, aka the connection. that's her 🫢
  • sess β€” a struct ksmbd_session *, aka the session of the connection. the connection's bestie, if you will 🌸
  • sess_key β€” a char *, and it's the derived session key output buffer. notice "output" β€” this one gets written into, iykyk πŸ‘‘

πŸ”₯ RETURN πŸ”₯

  • 0 on success πŸŽ‰
  • an error number on error πŸ’€

that's it. that's the whole return contract. no surprises, no plot twists, we love a clear communicator.


🌈 SEE ALSO 🌈

the kernel file lives at ./fs/smb/server/auth.c and she rolls with a whole squad β€” go say hi to all of them:


bestie reminder: if it returns a nonzero error number, that's not a slay, that's a genuine error. handle it πŸ’€

and that's the whole page πŸŽ€ this icon was compiled under ./fs/smb/server, dated October 2026, and it's the ksmbd_decode...sp_auth_blob(9) page β€” go forth and decode, you gorgeous kernel dev πŸ’–βœ¨
