lpfc_check_encryption(9)

💖 lpfc_check_encryption(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for lpfc_check_encryption — yes the (9) is part of the name, that's just how kernel docs roll, iykyk 🎀

---

✨ NAME ✨

lpfc_check_encryption — literally just reports an ndlp's encryption info 📋✨

---

🌸 SYNOPSIS 🌸

void lpfc_check_encryption (struct lpfc_hba *phba , struct lpfc_nodelist
*ndlp , struct lpfc_iocbq *cmdiocb , struct lpfc_iocbq *rspiocb );

like, it returns nothing (void) and takes four pointers. that's the whole vibe check 💅

---

🦋 ARGUMENTS 🦋

• phba — pointer to the lpfc hba data structure. the main character of the HBA world 👑
• ndlp — pointer to a node-list data structure. your node bestie 🫶
• cmdiocb — pointer to the lpfc command iocbq data structure. the outgoing one, going out first 🔥
• rspiocb — pointer to the lpfc response iocbq data structure. the one that comes back at you 😭

---

⭐ DESCRIPTION ⭐

so this routine gets called in the completion callback function for issuing or receiving a Port Login (PLOGI) command. both directions, no cap.

in a PLOGI completion, if FEDIF is supported, the encryption information will be provided in the completion status data. iconic.

and if phba supports FEDIF, a log message containing that encryption information gets logged. 📝

the encryption status is also saved for encryption reporting with the upper layer, through the rport encryption attribute. so it's double duty, she does it all 💅✨

ngl if you came here looking for encryption options to breathe on — there aren't any flags, bestie. it's just a function. the encryption info comes from the PLOGI completion when FEDIF is in the picture. periodt. 💀

okay that's the page!! love u, go read the rest of the ELS saga 🌈
