Running the standard syslogd-1.4.1-632 package, when I try to start syslogd by running "/etc/init.d/syslog start, I end up with these processes and no working syslog: root 29725 1 0 16:16 pts/0 00:00:00 /sbin/syslogd root 29726 29725 0 16:16 ? 00:00:00 [syslogd] <defunct> Manually starting syslogd under strace reveals the following behaviour in the child: [pid 30475] open("/var/run/syslogd.pid", O_RDONLY) = 0 [pid 30475] fstat64(0, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 [pid 30475] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7eef000 [pid 30475] read(0, "", 4096) = 0 [pid 30475] close(0) = 0 [pid 30475] munmap(0xb7eef000, 4096) = 0 [pid 30475] open("/var/run/syslogd.pid", O_RDWR|O_CREAT, 0644) = 0 [pid 30475] fcntl64(0, F_GETFL) = 0x2 (flags O_RDWR) [pid 30475] fstat64(0, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 [pid 30475] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7eef000 [pid 30475] _llseek(0, 0, [0], SEEK_CUR) = 0 [pid 30475] flock(0, LOCK_EX|LOCK_NB) = -1 EACCES (Permission denied) [pid 30475] read(0, "", 4096) = 0 [pid 30475] close(0) = 0 [pid 30475] munmap(0xb7eef000, 4096) = 0 [pid 30475] fstat64(1, 0xbfef5da8) = -1 EBADF (Bad file descriptor) [pid 30475] mmap2(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7eee000 [pid 30475] write(1, "Can\'t lock, lock is held by pid 0.\n", 35) = -1 EBADF (Bad file descriptor) [pid 30475] exit_group(1) = ?

The point where it all goes wrong is the failure of the flock() call. The man page for flock() doesn't document EACCES as an error code for it, and since syslogd is running as root and has the file open read/write, I can't see any obvious cause. The problem occurs on systems with both ReiserFS and EXT3 root filesystems, and even occurs if I replace the syslogd package with the one from openSUSE 10.2. syslogd worked correctly in openSUSE 10.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
