I'm not subscribed to this list, so be sure to CC mount.cifs fails if your password starts with a comma, but works with a comma in the middle. (eg. ",asdfasdf" does not work but "a,asdfasdf" works) also your password excluding the comma appears in dmesg for all to see perhaps also a malicious password could be created to add unwanted options to a user mountable fstab line. # mount -vvv /fs1 mount: fstab path: "/etc/fstab" mount: mtab path: "/etc/mtab" mount: lock path: "/etc/mtab~" mount: temp path: "/etc/mtab.tmp" mount: UID: 0 mount: eUID: 0 mount: spec: "//bcserver2/fs1" mount: node: "/fs1" mount: types: "cifs" mount: opts: "user=test,uid=test,gid=users,noauto" mount: external mount: argv[0] = "/sbin/mount.cifs" mount: external mount: argv[1] = "//bcserver2/fs1" mount: external mount: argv[2] = "/fs1" mount: external mount: argv[3] = "-v" mount: external mount: argv[4] = "-o" mount: external mount: argv[5] = "rw,noauto,user=test,uid=1000,gid=100" Password: (here I typed ",asdfasdf") mount.cifs kernel mount options: ip=10.3.0.5,unc=\\bcserver2\fs1,noauto,uid=1000,gid=100,ver=1,user=test,pass=******** mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) # dmesg | tail -n1 [1221917.271440] CIFS: Unknown mount option "asdfasdf" # grep cifs /etc/fstab //bcserver2/fs1 /fs1 cifs user=test,uid=test,gid=users,noauto # mount -V mount from util-linux 2.20.1 (with libblkid and selinux support) # cat /proc/version Linux version 3.8.4-1-default (geeko@buildhost) (gcc version 4.7.2 20130108 [gcc-4_7-branch revision 195012] (SUSE Linux) ) #1 SMP Fri Mar 22 23:08:34 UTC 2013 (20fc41c) -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
