mount.cifs fails when the share name must be converted to uppercase - e.g. for OS/2

[Günter Kukkukk]

As discussed in this thread
https://lists.samba.org/archive/samba/2014-June/182107.html
recent mount.cifs does not allow mounting of OS/2 shares, when
the share name has not been specified in uppercase.

After the first failing mount attempt, mount.cifs then converts
- host
- share name
- prefix
to uppercase and retries the mount.
This worked in former versions - but is failing now.

Using "strace" and looking at the source of mount.cifs.c
rc =3D mount(orig_dev, ".", cifs_fstype, parsed_info->flags, opti=
ons);
i noticed that the passed "orig_dev" parameter (e.g. //server/share) wa=
s
not converted to uppercase.

I also converted orig_dev to uppercase and it was working again:

diff --git a/mount.cifs.c b/mount.cifs.c
index 497665d..3535096 100644
--- a/mount.cifs.c
+++ b/mount.cifs.c
@@ -2097,7 +2097,8 @@ mount_retry:

+ uppercase_string(orig_dev)) {
fprintf(stderr,
"Retrying with upper case share=
name\n");
already_uppercased =3D 1;


I'm not a mount expert and only had a short look at the source, but
probably this is the culprit.

Should i open a bug report for this?
