security_sem_free(9)

📦 version 7.3.1, in nixpkgs unstable

💅 security_sem_free(9) 💅

okay so welcome to the Kernel API Manual, bestie — today's main character is security_sem_free(9), and honestly? She's a small one but she matters. 🎀

✨ NAME ✨

security_sem_free — frees a sysv semaphore LSM blob. that's it. that's the whole gig. 🫶

🌸 SYNOPSIS 🌸

void security_sem_free (struct kern_ipc_perm *sma );

🦋 ARGUMENTS 🦋

  • sma — the sysv ipc permission structure. yeah, the whole struct, she's the one holding the blob we're about to yeet 💅

🍓 DESCRIPTION 🍓

so what actually happens here? security_sem_free deallocates the security structure sma->security for the semaphore. that's the vibe: semaphore's done, its security blob gets freed, everybody goes home. ✨

like, sma->security specifically — not the sma itself, not anything else. just the security blob. no cap. 🌈

💜 SEE ALSO 💜

ngl this list is long long, but every single one of these is a real one, so here we go, in order, exactly as the kernel file ./security/security.c hands them to us: 👑

also the kernel file itself: ./security/security.c 🫶

and that's the whole page!! mwah 💋. for the record, the source is ./security and the date on this one is October 2026, and the page is literally named security_sem_free(9) — so yeah, now you know, bestie. go free those blobs responsibly. 🎀✨🧚‍♀️
