[Bug 676304] Re: Samba fails with files having colon in file name

[Ivan Kozik]

On xenial, I noticed that the Linux cifs client converts : to U+F022
(SFM_COLON) by default even when talking to a Samba with unix
extensions.  I think this happens in convert_to_sfm_char in linux's
fs/cifs/cifs_unicode.c.

You can use the undocumented mount option "nomapposix" to turn off those
character conversions, and then access to files with a colon works fine.

  Samba fails with files having colon in file name

  - Long file names including colon
  - Samba with mangling disabled

  I inserted "mangled names = no" to /etc/samba/smb.conf because I need
  to see long file names. That works ok except with those file names
  containing colon. I have a lot files containing colon in file name
  since those files are originally named according to date and time.
  That is very common with videos and photos. I have Linux-only
  environment i.e. colon is a legal character in a file name.

  Regression ?  Please see:
