label_components_match(9)

💖 NAME 💖

hiii bestie!! welcome to label_components_match(9), straight out of the Kernel API Manual ✨ this one is lowkey niche but it's giving kernel-internals main character energy, and we're gonna get through it together 🫶

label_components_match — find perms for all subcomponents of a label. periodt 💅

---

🌸 SYNOPSIS 🌸

int label_components_match (const struct aa_profile *profile , struct
       aa_ruleset *rules , struct aa_label *label , aa_state_t start , bool
       inview , u32 request , struct aa_perms *perms );

---

✨ ARGUMENTS ✨

• profile — profile to find perms for 🎀
• rules — ruleset to search 🔍
• label — label to check access permissions for 👑
• start — state to start match in 🌱
• inview — whether to match labels in view or only in scope 🦋
• request — permissions to request 🙈
• perms — an initialized perms struct to add accumulation to 💖

---

🌈 RETURN 🌈

the state the match finished in, may be the none matching state 😭

like, it hands back the state where the match ended up, and yes, that can be the none matching state — no cap, don't panic if that's what you get 💀

---

🦋 DESCRIPTION 🦋

okay so for the label A//B//C, this does the perm match for each of A and B and C ✨ all three get their moment, fr fr.

bestie, listen: perms should be preinitialized with allperms OR a previous permission check to be stacked. that's literally the setup 💅
