[Qemu-devel] [Bug 988128] Re: smbd crashes when called with "smb ports = 0"

[Thomas Huth]

The link from comment #2 does not work anymore ... does anybody know
whether the fix has been included in the QEMU repository?

Title:
  smbd crashes when called with "smb ports = 0"

Status in QEMU:
  Incomplete

Bug description:
  The smb.conf generated by qemu-kvm contains a "smb ports = 0" directive. This
  causes at least version 3.6.4 of Samba to crash with

  [0] vostro:/tmp/qemu-smb.6836-0# smbd -i -s smb.conf
  Unable to setup corepath for smbd: Operation not permitted
  smbd version 3.6.4 started.

  Changing "smb ports" to a non-privilileged port works around the
  issue.

  I'd like to help fix this, but I am not sure what qemu-kvm's intention is 
here.
  Zero is not a valid port, and the smb.conf manpage does not describe any
  special meaning of zero here. I found that previous versions of samba 
apparently
  did not bind to any port if zero was specified - but in that case, how is
  qemu communicating with samba?
