security_load_policy(9)

💅 security_load_policy(9) 💅

okay so this lil icon is from the Kernel API Manual, and it's literally about loading a security policy configuration. bestie, it's giving kernel security realness 💖

---

✨ NAME ✨

security_load_policy — load a security policy configuration.

---

🦋 SYNOPSIS 🦋

int security_load_policy (void *data , size_t len , struct
       selinux_load_state *load_state );

---

🌸 ARGUMENTS 🌸

• data — binary policy data, aka the raw policy bytes 👀
• len — length of data in bytes, so we know how much of it to read 💅
• load_state — policy load state, the lil state buddy for the load 🫶

---

🔥 DESCRIPTION 🔥

okay so here's the tea: this function loads a new set of security policy configuration data, validates it, and converts the SID table as necessary. no cap, it does all three. then it flushes the access vector cache after loading the new policy — periodt 💅✨

so yeah: validate the new policy, convert that SID table as needed, and flush the access vector cache once the new policy is in. iconic behavior tbh 👑
