Summary0004836: 4.* Compatibility Handling of GLOBOPS
DescriptionSimple issue:

In UnrealIRCd 3.2 allowed GLOBOPS messages to be sent with a user as the source of the message without an error being generated.

In UnrealIRCd 4.* the same GLOBOPS is simply changed to a SENDUMODE o with the source and message unchanged. This results in a GLOBOPS from services servers with a service pseudo user as a source causing the second server in the chain to respond with an error stating SENDUMODE is not available to users.

Example (taken from the Anope bug report):

Services sends this to it's uplink:
:00BAAAAAD GLOBOPS :ADMIN: <removed>!<removed>@<removed> (<removed>) used GLOBAL
The UnrealIRCd 4 uplink converts this to the following and sends to its linked servers:
:00BAAAAAD SENDUMODE o :from OperServ: ADMIN: <removed>!<removed>@<removed> (<removed>) used GLOBAL
The next linked servers then respond with:
:<removed> 487 Global :SENDUMODE is a server only command
Steps To ReproduceSend a GLOBOPS message from a services server with a user such as OperServ as the source where the network consists of a services server and at least 2 linked UnrealIRCd 4 servers.
Additional InformationThis was discovered by an Anope user reporting the error sent in reply to the SENDUMODE message that resulted from a GLOBOPS sent from Anope.
