ecryptfs_setattr(9)

✨ NAME ✨

ecryptfs_setattr — that's literally the NAME line, bestie; the original leaves the description side empty 😭💅

okay so real quick: this page is ecryptfs_setattr from the Kernel API Manual, section 9. Yes we're in kernel API land, stay with me 🫶

💖 SYNOPSIS 💖

int ecryptfs_setattr (struct mnt_idmap *idmap , struct dentry *dentry , struct iattr *ia );

🎀 ARGUMENTS 🎀

• idmap — idmap of the target mount 🗺️
• dentry — dentry handle to the inode to modify 🪄
• ia — Structure with flags of what to change and values 📝

🦋 DESCRIPTION 🦋

So this function updates the metadata of an inode. Slay.

If the update is to the size — i.e. truncation — then ecryptfs_truncate will handle the size modification of both the ecryptfs inode and the lower inode. That's the size-change situation, iykyk 🌸

All other metadata changes will be passed right to the lower filesystem, and we will just update our inode to look like the lower. No cap, that's the whole vibe 💖
