From d7e3ef70b601831d5bef3fef21fa16b761f561e8 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Tue, 7 Nov 2023 18:14:11 +0100 Subject: lib: Fix timeout overflow on 32-bit systems The timeout comparison for keepalives could overflow on 32-bit systems, as times were converted to nanoseconds and be limited to a bit over 4 seconds. This caused flow reads to fail miserably with EFLOWPEER errors when keepalives were set higher on these systems.
