nfs_stream_decode_acl(9)

💅 nfs_stream_decode_acl(9) — like, the NFSv3 ACL decoder, bestie

okay so real talk: this is a page straight out of the Kernel API Manual, and the star of the show is nfs_stream_decode_acl. she decodes an NFSv3 ACL and she does it iconically. no cap. 🎀

✨ NAME ✨

nfs_stream_decode_acl — Decode an NFSv3 ACL. that's it, that's the vibe. 🦋

---

🌸 SYNOPSIS 🌸

bool nfs_stream_decode_acl (struct xdr_stream *xdr , unsigned int
*aclcnt , struct posix_acl **pacl );

---

💖 ARGUMENTS 💖

• xdr — an xdr_stream positioned at an encoded ACL. like, she's already standing at the door, you just gotta let her in 🫶
• aclcnt — OUT: count of ACEs in decoded posix_acl. she tells you how many lil ACEs she found 💅
• pacl — OUT: a dynamically-allocated buffer containing the decoded posix_acl. this one's the main character, fr fr 👑

---

🔥 DESCRIPTION 🔥

so the whole point is the return values, and they're giving two very different energies:

• false: The encoded ACL is not valid. 💀 awkward. the vibes are off, nothing to see here.
• true: pacl contains a decoded ACL, and xdr is advanced. slay!! it worked, and xdr has officially moved on to the next thing ✨

🚨 okay bestie, listen, this is the important part: On a successful return, caller must release *pacl using posix_acl_release. it's a dynamically-allocated buffer, so if you forget to release it that's a literal memory leak and we do not do those. periodt. 🧚
