From 257a73031d29447ee82fe06d2b97d8564f63276d Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 23 Aug 2017 11:57:51 +0200 Subject: net/sock: allow the user to set negative peek offset This is necessary to allow the user to disable peeking with offset once it's enabled. Unix sockets already allow the above, with this patch we permit it for udp[6] sockets, too. Fixes: 627d2d6b5500 ("udp: enable MSG_PEEK at non-zero offset") Signed-off-by: Paolo Abeni Acked-by: Willem de Bruijn Signed-off-by: David S.
