> New action to decrement TTL instead of setting it to a fixed value. > This action will decrement the TTL and, in case of expired TTL, drop it > or execute an action passed via a nested attribute. > The default TTL expired action is to drop the packet. > > Supports both IPv4 and IPv6 via the ttl and hop_limit fields, respectively. > > Tested with a corresponding change in the userspace: > > # ovs-dpctl dump-flows > in_port(2),eth(),eth_type(0x0800), packets:0, bytes:0, used:never, > actions:dec_ttl{ttl<=1 action:(drop)},1 > in_port(1),eth(),eth_type(0x0800), packets:0, bytes:0, used:never, > actions:dec_ttl{ttl<=1 action:(drop)},2 > in_port(1),eth(),eth_type(0x0806), packets:0, bytes:0, used:never, > actions:2 > in_port(2),eth(),eth_type(0x0806), packets:0, bytes:0, used:never, > actions:1 > > # ping -c1 192.168.0.2 -t 42 > IP (tos 0x0, ttl 41, id 61647, offset 0, flags [DF], proto ICMP (1), > length 84) > 192.168.0.1 > 192.168.0.2: ICMP echo request, id 386, seq 1, length 64 > # ping -c1 192.168.0.2 -t 120 > IP (tos 0x0, ttl 119, id 62070, offset 0, flags [DF], proto ICMP (1), > length 84) > 192.168.0.1 > 192.168.0.2: ICMP echo request, id 388, seq 1, length 64 > # ping -c1 192.168.0.2 -t 1 > # > > Co-developed-by: Bindiya Kurle <bindiyaku...@gmail.com> > Signed-off-by: Bindiya Kurle <bindiyaku...@gmail.com> > Signed-off-by: Matteo Croce <mcr...@redhat.com> net-next is closed, please resubmit this when it opens back up.
