📦 version 7.3.1, in nixpkgs unstable

💖 s5p_hash_prepare_request(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one lives in the kernel and it's called s5p_hash_prepare_request, and honestly? it's giving "get your request ready before the real work starts" ✨

🌸 NAME 🌸

s5p_hash_prepare_request — prepare request for processing 🎀

⭐ SYNOPSIS ⭐

int s5p_hash_prepare_request (struct ahash_request *req , bool update );

like, that's the whole signature, no cap 💅

🦋 ARGUMENTS 🦋

  • req — AHASH request 👑 that's the request we're prepping, bestie
  • update — true if UPDATE op ✅ (literally just a bool telling us it's an update)

🔥 DESCRIPTION 🔥

okay so two things, and you gotta know both of them, iykyk:

Note 1: we can have update flag _and_ final flag at the same time. yes, both. at once. iconic behavior honestly 💀

Note 2: we enter here when digcnt > BUFLEN (= HASH_BLOCK_SIZE) or either req->nbytes or ctx->bufcnt + req->nbytes is > BUFLEN or we have final op 🌈

like, one of those conditions hits and we're in, periodt 🫶
