security_sem_alloc(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, welcome to security_sem_alloc(9) from the Kernel API Manual — this is the page for the girlies who need to know about the sysv semaphore LSM blob situation. ✨

security_sem_alloc — Allocate a sysv semaphore LSM blob 💅

✨ SYNOPSIS ✨

int security_sem_alloc (struct kern_ipc_perm *sma );

🫶 ARGUMENTS 🫶

  • sma — sysv ipc permission structure. That's the whole argument, bestie: the sysv ipc permission structure. No cap. 🎀

🧚 DESCRIPTION 🧚

Allocate and attach a security structure to the sma security field. The security field is initialized to NULL when the structure is first created.

So picture it: when the structure is first created, that security field starts out as NULL, and this function is the one that allocates and attaches the security structure to it. It's giving “set up the security blob” energy, and honestly? iconic. 🦋

🔥 RETURN 🔥

Returns 0 if operation was successful and permission is granted.

That's the return vibe: 0 means the operation was successful and permission is granted. periodt. 💖
