security_bpf_map(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

security_bpf_map — Check if access to a bpf map is allowed. This is the security_bpf_map(9) page from the Kernel API Manual, bestie, and it's here to explain the little security vibe check for bpf map access.

✨ SYNOPSIS ✨

int security_bpf_map (struct bpf_map *map , fmode_t fmode );

🫶 ARGUMENTS 🫶

  • map — bpf map. Yep, the bpf map in question.
  • fmode — mode. The mode for this whole situation.

🌸 DESCRIPTION 🌸

Okay so picture this: the kernel is about to generate and return a file descriptor for eBPF maps, and this function does a check right then. That's the moment. It's the security check for that exact fd-generating, fd-returning scenario. No extra lore, no side quests — just the check.

⭐ RETURN ⭐

Returns 0 if permission is granted. That's the documented return, bestie: 0 means permission is granted. Periodt.
