Hello, I tried using the rstpd daemon from http://git.kernel.org/?p=linux/kernel/git/shemminger/rstp.git;a=summary which worked fine on my desktop. I then tried doing the same on my embedded atom baord and failed. It turned out the used kernel 2.6.38-gentoo-r6 had not the problem the kernel v2.6.39 used on atomboard had. After trying a 2.6.39 based kernel on my desktop the same problem occured. After bisecting I ended up at commit afc6151a78a43bdca5f64a8bd3e3c13837580c54 "bridge: implement [add/del]_slave ops" My /sbin/bridge-stp is the one from commit b27ab0efa4ecf7a839f750ec1e9b9092c577ebbb in the rstpd repository. My steps to reproduce: * start rstpd (I used rstpd -d -v2 from a different terminal to see the error messages) * echo $(pgrep rstpd) > /var/run/rstpd.pid * brctl addbr br1 * echo 1 > /sys/class/net/br1/bridge/stp_state * brctl addif br1 eth1 * brctl addif br1 eth2 * ifconfig br1 up 192.168.0.20 * ifconfig eth1 up * ifconfig eth2 up Then I get the following output from rstpd: 7: br1 2011-06-30 09:08:01 create_if: Add bridge br1 2011-06-30 09:08:01 CTL_enable_bridge_rstp: bridge 7, enable 1 3: eth1 master br1 2011-06-30 09:08:01 stp_enabled: STP on br1 state 2 2011-06-30 09:08:01 set_br_up: br1 was up stp was down 2011-06-30 09:08:01 set_br_up: Set bridge br1 up stp up 2011-06-30 09:08:01 create_if: Add iface eth1 to bridge br1 2: eth2 master br1 2011-06-30 09:08:01 create_if: Add iface eth2 to bridge br1 7: br1 2011-06-30 09:08:01 Error in bridge_bpdu_rcv at bridge_track.c:585 verifying ifc->up. 2: eth2 master br1 2011-06-30 09:08:03 Error in bridge_bpdu_rcv at bridge_track.c:585 verifying ifc->up. 2011-06-30 09:08:03 Error in bridge_bpdu_rcv at bridge_track.c:585 verifying ifc->up. 2011-06-30 09:08:05 Error in bridge_bpdu_rcv at bridge_track.c:585 verifying ifc->up. 2011-06-30 09:08:05 Error in bridge_bpdu_rcv at bridge_track.c:585 verifying ifc->up. The last error messages are printed for each BPDU received at the bridge. Reverting the named commit on v2.6.39.2 restores the old behavior and I get a working RSTP again. BTW: I noticed that in 2.6.39.2 independently from this patch revert this bridge didn't show up RUNNING ifconfg. Is this intended? Another bridge I have, which doesn't use (R)STP, is shown as RUNNING like before.
