From 81840b3b91aad06053ad2712f3da5d0448eeb0e8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 7 Jun 2023 19:19:08 +0100 Subject: [PATCH] tls: Allow MSG_SPLICE_PAGES but treat it as normal sendmsg Allow MSG_SPLICE_PAGES to be specified to sendmsg() but treat it as normal sendmsg for now. This means the data will just be copied until MSG_SPLICE_PAGES is handled.
