Package: mount Version: 2.12p-4 Severity: normal Hello,
when I try to umount a partition mounted by the same user before, the operation fails and I get a segmentation fault. On partitions mounted by root, there is a proper message: $ umount /mnt/c umount: only root can unmount /dev/hda1 from /mnt/c $ umount /mnt/d Segmentation fault $ mount ... /dev/hda1 /mnt/c vfat rw,nodiratime,nosuid,nodev,noexec,fmask=0000,dmask=0000,codepage=cp437,iocharset=utf8,utf8 0 0 /dev/sda1 /mnt/d vfat rw,nodiratime,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0000,dmask=0000,codepage=cp437,iocharset=utf8,utf8 0 0 $ cat /etc/fstab ... /dev/hda1 /mnt/c vfat auto,user,umask=000,utf8 0 0 UUID="41EB-F193" /mnt/d vfat auto,user,umask=000,utf8 0 0 This looks odd, I cannot see the reasons for a) not allowing the umount and b) the segmentation fault. strace says: ... readlink("/mnt", 0xbfffd820, 4096) = -1 EINVAL (Invalid argument) readlink("/mnt/d", 0xbfffd820, 4096) = -1 EINVAL (Invalid argument) umask(077) = 022 open("/etc/mtab", O_RDONLY|O_LARGEFILE) = 3 umask(022) = 077 fstat64(3, {st_mode=S_IFREG|0644, st_size=998, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fe8000 read(3, "/dev/ide/host0/bus0/target0/lun0"..., 4096) = 998 read(3, "", 4096) = 0 close(3) = 0 munmap(0xb7fe8000, 4096) = 0 stat64("/sbin/umount.vfat", 0xbffff6f0) = -1 ENOENT (No such file or directory) oldumount("/mnt/d") = -1 EPERM (Operation not permitted) oldumount("/dev/scsi/host3/bus0/target1/lun0/part1") = -1 ENOENT (No such file or directory) lstat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=998, ...}) = 0 open("/etc/mtab", O_RDWR|O_CREAT|O_LARGEFILE, 0644) = -1 EACCES (Permission denied) write(2, "umount: /dev/scsi/host3/bus0/tar"..., 59umount: /dev/scsi/host3/bus0/target1/lun0/part1: not found ) = 59 write(2, "umount: /mnt/d: must be superuse"..., 44umount: /mnt/d: must be superuser to umount ) = 44 stat64("/sbin/umount.vfat", 0xbffff6f0) = -1 ENOENT (No such file or directory) oldumount("/mnt/d") = -1 EPERM (Operation not permitted) oldumount("/dev/scsi/host3/bus0/target1/lun0/part1") = -1 ENOENT (No such file or directory) write(2, "umount: /dev/scsi/host3/bus0/tar"..., 59umount: /dev/scsi/host3/bus0/target1/lun0/part1: not found ) = 59 write(2, "umount: /mnt/d: must be superuse"..., 44umount: /mnt/d: must be superuser to umount ) = 44 exit_group(1) = ?
