[Bug 1481561] Re: Connect to XDMCP clients on address requests come from if available
** Description changed: - Currently LightDM connects to an XDMCP enabled X server using the first - suitable address in the XDMCP Request packet. However, some clients may - put a number of addresses in this message and potentially they are not - all routable. If the address the request message came from is in the - list we should use that first as that is more likely to be a routable - address. This also matches the behaviour of GDM which ignores the - contents of the Request packet anyway. + [Impact] + Currently LightDM connects to an XDMCP enabled X server using the first suitable address in the XDMCP Request packet.

Connect with a client that puts a number of addresses in the Request packet + + Expected result: + LightDM prefers the address the Request came from over the other addresses. + + Observed result: + LightDM always picks the first address. + + [Regression Potential] + There is a possibility of a behaviour change in existing clients that had two valid addresses, though the particular address shouldn't matter (unless complex firewalling / routing rules are being used). There is a risk that XDMCP behaviour could have been broken by the change (tested with regression tests). ** Changed in: lightdm/1.14 Status: Fix Committed => Fix Released ** Also affects: lightdm (Ubuntu Vivid) Importance: Undecided Status: New ** Changed in: lightdm (Ubuntu Vivid) Status: New => Triaged ** Changed in: lightdm (Ubuntu Vivid) Importance: Undecided => Medium ** Changed in: lightdm (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1481561 Title: Connect to XDMCP clients on address requests come from if available To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1481561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
