From 481d01fa2b07d3c6f9e6ef9ae239bc616b1ac757 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 16 Mar 2020 13:50:23 +0100 Subject: [PATCH] y2038: nscd: Modify nscd_helper to use __clock_gettime64 The nscd/nscd_helper.c uses __clock_gettime to get current time and on this basis calculate the relative timeout for poll. By using __clock_gettime64 on systems with __WORDSIZE == 32 && __TIMESIZE != 64 the timeout is correctly calculated after time_t overflow. --- nscd/nscd_helper.c | 17 +++++++++-------- 1 file changed, 9 insertions(+), 8 deletions(-) diff --git a/nscd/nscd_helper.c b/nscd/nscd_helper.c index d2d7d15f26..a4f3312f90 100644 --- a/nscd/nscd_helper.c +++ b/nscd/nscd_helper.c @@ -37,6 +37,7 @@ #include #include #include +#include #include "nscd-client.h" @@ -59,10 +60,10 @@ wait_on_socket (int sock, long int usectmo) /* Handle the case where the poll() call is interrupted by a signal.
