ecryptfs_parse_packet_set(9)

💅 ecryptfs_parse_packet_set(9) 💅

okay so bestie, welcome to the Kernel API Manual page for ecryptfs_parse_packet_set(9). this is the whole page, and we are keeping every single detail: the args, the return vibes, the see-also girlies, all of it. no cap. ✨

🌸 NAME 🌸

• ecryptfs_parse_packet_set — the description slot after the dash is literally empty on this page. it’s just ecryptfs_parse_packet_set - and then nothing, bestie. 💀

✨ SYNOPSIS ✨

int ecryptfs_parse_packet_set (struct ecryptfs_crypt_stat *crypt_stat ,
unsigned char *src , size_t src_size , struct dentry *ecryptfs_dentry );

🎀 ARGUMENTS 🎀

• crypt_stat — the cryptographic context. that’s the whole description, and honestly it’s giving main character energy for this function. 👑
• src — the virtual address of the region of memory containing the packets. keep it exact: Virtual address of region of memory containing the packets. 🦋
• src_size — the size of the packet set buffer. yes bestie, it’s the size. 🎀
• ecryptfs_dentry — the eCryptfs dentry associated with the packet set. that’s the dentry link-up. 🌸

🦋 DESCRIPTION 🦋

the mission, if we choose to accept it: get crypt_stat to have the file's session key if the requisite key is available to decrypt the session key. that’s the core vibe. 🔥

Returns: Zero if a valid authentication token was retrieved and processed. a negative value happens for file not encrypted or for error conditions. so zero is the slay outcome, negative is the “not encrypted / error” outcome, periodt. 💅
