Hi!
Sorry for topposting, but I don't know if this has got something to do with your changes:
I am trying to rebuild my -CURRENT system now for some days and keep receiving panic messages from ng_ppoe
like this
panic NG_MKMESSAGE() with how=M_DONTWAIT(1) at line 913 in file /usr/src/sys/netgraph/ng_pppoe.c ...
netgraph/pppoe is used by ppp to connect to my ISP . My last working kernel was built on May 31 .
Thanks, if you know how to repair this.
Uli.

If you don't know or care about netgraph metadata (e.g. packet priority) then this shouldn't worry you.
We are changing the netgraph metadata facility (in which arbitrary metadata can be sent with a packet through processing) to use the mbuf TAG facility that has been imported by sam.
Netgraph tags will use different cookies to the standard set of tags imported with the code, so they will live in a separate namespace, however they will be handled during GC and manipulation by the standard tag handling code (Thanks to Sam for giving us the cookie facility).
In the checked in code there are only a couple of users of metadata, but there may be 3rd parties out there that use it. If so the authors should contact me as soon as possible to co-ordinate the changeover.
For example the BW_MAN bandwith manager uses metadata to tag packets selected by its ipfw netgraph node.
Currently the biggest user of metadata is the frame relay LMI node that tags LMI packets with a higher priority in order to meet timing constraints given by the standards.
In addition the ng_ksocket node adds info into metadata and I suspect there are people using that.
