[Bug 1680224] Re: auto.smb fails on Windows administrative shares

[Ian Kent]

In reviewing the first patch I've found another problem with
mapent_len possibly not being initialized.

Note the order of application of the patch is:
autofs-5.1.2 - use malloc for expanded map location
autofs-5.1.2 - fix offset mount location multiple expansion

and, although they are against current upstream they should apply.
If not then ask and I'll fix them.

** Patch added: "Patch - use malloc for expanded map location"

Title:
  auto.smb fails on Windows administrative shares

Status in autofs package in Ubuntu:
  Triaged

Bug description:
  This is probably related to #385244.

  I've been unable to get a Windows administrative share (ie. C$)
  mounted through Autofs. Non-administrative shares work fine.
  Administrative shares are accessible with the same credentials from
  other Windows 10 workstations and through smbclient on Ubuntu (16.04
  LTS) machines. Administrative shares can even be mounted using the
  same credentials via mount on the command-line. However, autofs will
  not mount the same shares, using the same credentials, on the same
  Ubuntu machine.

  Administrative shares are listed under /cifs/WindowsHostName, but a cd
  /cifs/WindowsHostname/C$ results in "-bash: cd: C$: No such file or
  directory" from the shell and the following output from 'automount -f
  -v':

  -----
  attempting to mount entry /cifs/WindowsHostname/C$
  >> Retrying with upper case share name
  >> mount error(6): No such device or address
  >> Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
  mount(generic): failed to mount //WindowsHostname/C\$ (type cifs) on /cifs/WindowsHostname/C$
  failed to mount /cifs/WindowsHostname/C$
  -----

  Notice that mount complains of failing to mount 'C\$' rather than
  'C$'. If the bit of awk script that escapes the $ is removed, it then
  fails to mount 'C', which is also no good. I think if we could
  actually get mount to try to mount 'C$', it would work.
