NE_ERR_INVALID_FLAG_VALUE(9)

💅 NE_ERR_INVALID_FLAG_VALUE(9) — Kernel API Manual ✨

okay so bestie, welcome to NE_ERR_INVALID_FLAG_VALUE(9), straight out of the Kernel API Manual and honestly? it's a short one but she matters. this is the error-code page you land on when you passed a flag value that is, and I cannot stress this enough, invalid. that's it, that's the whole vibe. 🎀

🌸 NAME 🌸

NE_ERR_INVALID_FLAG_VALUE — literally just: the provided flag value is invalid. no cap, that's the description. she's concise, she's iconic, she's telling you your flag is cooked. 💀

✨ SYNOPSIS ✨

NE_ERR_INVALID_FLAG_VALUE

that's it. no arguments, no options, no return values — just the error code name sitting there looking at you. main character energy fr fr. 🦋

🔥 SEE ALSO 🔥

ngl this is where the page goes off — the related-reading list is huge and honestly it's giving "linked to the entire Nitro Enclaves cinematic universe." the source of truth lives in the kernel file ./include/uapi/linux/nitro_enclaves.h, and from there you got the whole NE (Nitro Enclaves) squad:

• Nitro Enclaves (NE) Kernel Driver Interface(9) — the big mama page, start here 🫶
• NE_CREATE_VM(9)
• NE_ADD_VCPU(9)
• NE_GET_IMAGE_LOAD_INFO(9)
• NE_SET_USER_MEMORY_REGION(9)
• NE_START_ENCLAVE(9)

then the error-code family reunion 👑:

• NE specific error codes(9)
• NE_ERR_VCPU_ALREADY_USED(9)
• NE_ERR_VCPU_NOT_IN_CPU_POOL(9)
• NE_ERR_VCPU_INVALID_CPU_CORE(9)
• NE_ERR_INVALID_MEM_REGION_SIZE(9)
• NE_ERR_INVALID_MEM_REGION_ADDR(9)
• NE_ERR_UNALIGNED_MEM_REGION_ADDR(9)
• NE_ERR_MEM_REGION_ALREADY_USED(9)
• NE_ERR_MEM_NOT_HUGE_PAGE(9)
• NE_ERR_MEM_DIFFERENT_NUMA_NODE(9)

• NE_ERR_NO_CPUS_AVAIL_IN_POOL(9)
• NE_ERR_INVALID_PAGE_SIZE(9)
• NE_ERR_INVALID_ENCLAVE_CID(9)

and the flag / struct besties 🧚:

• Image load info flags(9)
• NE_EIF_IMAGE(9)
• struct ne_image_load_info(9)
• User memory region flags(9)
• NE_DEFAULT_MEMORY_REGION(9)
• struct ne_user_memory_region(9)
• Enclave start info flags(9)
• NE_ENCLAVE_PRODUCTION_MODE(9)
• NE_ENCLAVE_DEBUG_MODE(9)
• struct ne_enclave_start_info(9)

like… go read them?? they're all right there?? iykyk 🌈

lowkey a warning but also just facts: this page gives you nothing beyond the error name and the reading list — the actual behaviour lives in those pages above, so don't be out here guessing. 🙈

💖 that's the whole page, periodt 💖

this little cutie is served up from the ./include/uapi/linux corner of the kernel tree, dated October 2026, section 9 of the manual, and she says bye bestie — slay your flags next time 💅✨🍓
