Yes, the current upstream code also cares about mk_exit_code() result (where we check status of the helper). Upstream commit 8ab82185eed76bc20694a197fe10c5f9fb795b80. Note that I don't think that the incorrect verbose message is a urgent issue. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:2186 |
Description of problem: mount -av" report NFS "successfully mounted" in RHEL 7.2 with util-linux-2.23.2-26.el7_2.2.x86_64 but it is not. Version-Release number of selected component (if applicable): RHEL 7.2 3.10.0-327.13.1.el7.x86_64 util-linux-2.23.2-26.el7_2.2.x86_64 Steps to Reproduce: [root@dhcp233-147 ~]# cat /etc/exports /iptvstage *(rw,sync) [root@dhcp8-30 ~]# grep -i iptvstage /etc/fstab 10.65.2.185:/iptvstage /iptvstage nfs defaults,intr,_netdev 0 0 [root@dhcp8-30 ~]# mount -a mount.nfs: mount point /iptvstage does not exist <-------- [root@dhcp8-30 ~]# mount -av / : ignored /boot : already mounted swap : ignored mount.nfs: mount point /iptvstage does not exist /iptvstage : successfully mounted <----------shows as mounted man page of mount: -v, --verbose Verbose mode. -a, --all Mount all filesystems (of the given types) mentioned in fstab. But if you see df-h, /proc/mounts output it doesnt get mounted. [root@dhcp8-30 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel_dhcp8--30-root 4.0G 1.4G 2.6G 35% / devtmpfs 486M 0 486M 0% /dev tmpfs 496M 0 496M 0% /dev/shm tmpfs 496M 57M 440M 12% /run tmpfs 496M 0 496M 0% /sys/fs/cgroup /dev/vda1 497M 125M 373M 26% /boot tmpfs 100M 0 100M 0% /run/user/0 [root@dhcp8-30 ~]# grep -i iptvstage /proc/mounts [root@dhcp8-30 ~]# ls /iptvstage ls: cannot access /iptvstage: No such file or directory Actual results: mount -av showing as mounted which is incorrect. [root@dhcp8-30 ~]# mount -av / : ignored /boot : already mounted swap : ignored mount.nfs: mount point /iptvstage does not exist /iptvstage : successfully mounted Expected results: mount -av / : ignored /boot : already mounted swap : ignored mount.nfs: mount point /iptvstage does not exist Additional info: The "successfully mounted" message came from the following code: util-linux-2.23.2/sys-utils/mount.c 173 static int mount_all(struct libmnt_context *cxt) 174 { ... 199 } else { 200 mk_exit_code(cxt, mntrc); /* to print warning s */ 201 202 if (mnt_context_get_status(cxt)) { 203 nsucc++; 204 205 if (mnt_context_is_verbose(cxt)) 206 printf("%-25s: successfully mounted ", tgt); 207 } else 208 nerrs++; 209 } ... This is because mnt_context_get_status(cxt) is constantly true for NFS mounts. Its code: util-linux-2.23.2/libmount/src/context.c 1982 int mnt_context_get_status(struct libmnt_context *cxt) 1983 { 1984 assert(cxt); 1985 return !cxt->syscall_status || !cxt->helper_exec_status; 1986 }
