| 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. |
