Hi, this patch series adds support for setting the skb mark value as socket option. It's not possible yet to change this after the socket is created, although the mark value can be changed afterwards.
How to test it: 1. Setup mark values echo 0xcafe > /sys/kernel/config/dlm/cluster/mark echo 0xbeef > /sys/kernel/config/dlm/cluster/comms/2/mark Note: setting a mark value for local node has no effect. 2. Add some skb mark classifier: tc qdisc add dev $DEV root handle 1: htb tc filter add dev $DEV parent 1: u32 match mark 0xcafe 0xffffffff action ok tc filter add dev $DEV parent 1: u32 match mark 0xbeef 0xffffffff action ok 3. Mount e.g. gfs2 4. dump stats: tc -s -d filter show dev $DEV 5. Open e.g. wireshark and check the success rate of stats I have also patches for dlm user space to set these values via dlm controld. - Alex changes since v2: - rebase on current dlm/next branch - because rebase it's necessary now to add PATCH 1/3. Please netdev maintainers, reply if it's okay to merge this one patch into dlm/next. Due other patches in dlm/next it's as well not possible to merge everything in net-next. Thanks.
