| 4 | Subject: [PATCH] configure.ac: support large-file for stat64 |
| 5 | |
| 6 | While starting dbus-daemon on a 32-bit linux host and it invokes |
| 7 | fstat to load /etc/dbus-1/system.conf through NFS. If system.conf |
| 8 | was created with a large indoe number on 64-bit host. The above |
| 9 | fstat invoking failed. Here is the log of strace: |
| 10 | ............ |
| 11 | $ ls -i /etc/dbus-1/system.conf |
| 12 | 53778558109 /etc/dbus-1/system.conf |
| 13 | |
| 14 | $ strace /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation |
| 15 | |open("/etc/dbus-1/system.conf", O_RDONLY) = 4 |
| 16 | |fstat64(4, {st_mode=S_IFREG|0644, st_size=3340, ...}) = 0 |
| 17 | |close(4) = 0 |
| 18 | |close(3) = 0 |
| 19 | |write(2, "Failed to start message bus: Fai"..., 109Failed to start message bus: |
| 20 | Failed to stat "/etc/dbus-1/system.conf": Value too large for defined data type |
| 21 | |) = 109 |
| 22 | |exit_group(1) = ? |
| 23 | |+++ exited with 1 +++ |
| 24 | ............ |
| 25 | |
| 26 | In this situation, we should support large-file for stat64. Add marco |
| 27 | AC_SYS_LARGEFILE to do the detection at configure time. It can be disabled |
| 28 | by configuring with the `--disable-largefile' option. |
