From e18bd3a571be716d90bedc835a014472470ae7bd Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Wed, 30 Dec 2015 10:58:39 +0800 Subject: [PATCH] configure.ac: support large-file for stat64 While starting dbus-daemon on a 32-bit linux host and it invokes fstat to load /etc/dbus-1/system.conf through NFS. If system.conf was created with a large indoe number on 64-bit host. The above fstat invoking failed. Here is the log of strace: ............ $ ls -i /etc/dbus-1/system.conf 53778558109 /etc/dbus-1/system.conf $ strace /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation |open("/etc/dbus-1/system.conf", O_RDONLY) = 4 |fstat64(4, {st_mode=S_IFREG|0644, st_size=3340, ...}) = 0 |close(4) = 0 |close(3) = 0 |write(2, "Failed to start message bus: Fai"..., 109Failed to start message bus: Failed to stat "/etc/dbus-1/system.conf": Value too large for defined data type |) = 109 |exit_group(1) = ? |+++ exited with 1 +++ ............ In this situation, we should support large-file for stat64. Add marco AC_SYS_LARGEFILE to do the detection at configure time. It can be disabled by configuring with the `--disable-largefile' option.
