It's based on our old initiator code as well as SCST, neither of which are in-kernel.
Sivaram, Joe and Mike have been discussing some patches recently to update the target to get it working again. IMO if we want an FCoE target we need to decide on which framework to use. Either SCST needs to get in-kernel or we need to base the FCoE target on stgt. My understanding is that the main difference in the two projects is that SCST is mostly kernel code where stgt is mostly user space code (with some kernel components which are allready upstream). There have been a lot of technical discussions on the subject of what the target infrastructure should look like on linux-scsi. So, depending on which direction is decided upon one would then need to either hook our upstream initiator into SCST (once it's upstream) or port our current initiator code to userspace to work with stgt. > I read in some places that FCoE target is/is been implemented to work > with tgt too.

It was old code though. I don't think that much testing was ever done on it and I'm not sure if any effort has been made to update the code. _______________________________________________ devel mailing list [email protected] http://www.open-fcoe.org/mailman/listinfo/devel
