ecryptfs_cop..._with_header(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ecryptfs_copy_up_encrypted_with_header(9) ✨

okay bestie, welcome to another page of the Kernel API Manual 💅 section 9 of the man pages, no less — this one's all about ecryptfs_copy_up_encrypted_with_header, and yes, the actual header of this page truncates it to ecryptfs_cop..._with_header(9) because even man pages gotta keep it cute and abbreviated 🎀 but we're using the full name down here, iykyk.

🌸 NAME 🌸

ecryptfs_copy_up_encrypted_with_header — literally the function, that's it, that's the name, the manpage lists nothing after the dash and we respect that 🙈

🦋 SYNOPSIS 🦋

int ecryptfs_copy_up_encrypted_with_header (struct folio *folio , struct ecryptfs_crypt_stat *crypt_stat );

that's the whole signature, copy it exactly bestie, character for character, don't you dare "fix" the spacing ⭐

💜 ARGUMENTS 💜

  • folio — okay so this one is sort of a "virtual" representation of the encrypted lower file 👀 and here's the tea: the actual lower file does not have the metadata in the header. Also important — this is locked. 🔒 don't forget the lock, fr fr.
  • crypt_stat — the eCryptfs inode's cryptographic context ✨ that's the whole description, she's short and she knows it 💅

🌈 DESCRIPTION 🌈

so the "view" is the version of the file that userspace winds up seeing 👑 with the header information inserted. that's the vibe. that's the whole description. main character energy, minimal words, maximum meaning 🫶

⭐ SEE ALSO ⭐

go read these next, bestie, they're all in the kernel file ./fs/ecryptfs/mmap.c 🦋:

🎀 friendly reminder that every single detail up there is load-bearing — the lock on folio, the fact that the actual lower file doesn't carry the header metadata, and all three SEE ALSO refs. don't skip 'em. periodt. 💅

and that's a wrap, mwah 💖 this page came to you from ./fs/ecryptfs, dated October 2026, and the header/footer were keeping the same ecryptfs_cop..._with_header(9) energy the whole time 😭 stay encrypted, stay iconic, see you in section 9 🌈👑🍓
