2016-09-13net: bridge: add helper to call /sbin/bridge-stpVivien Didelot
If /sbin/bridge-stp is available on the system, bridge tries to execute it instead of the kernel implementation when starting/stopping STP. If anything goes wrong with /sbin/bridge-stp, bridge silently falls back to kernel STP, making hard to debug userspace STP. This patch adds a br_stp_call_user helper to start/stop userspace STP and debug errors from the program: abnormal exit status is stored in the lower byte and normal exit status is stored in higher byte. Below is a simple example on a kernel with dynamic debug enabled: # ln -s /bin/false /sbin/bridge-stp # brctl stp br0 on br0: failed to start userspace STP (256) # dmesg br0: /sbin/bridge-stp exited with code 1 br0: failed to start userspace STP (256) br0: using kernel STP Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2016-09-10Merge branch 'vrf-tx-hook'David S. Miller
David Ahern says: ==================== net: Convert vrf to tx hook The motivation for this series is that ICMP Unreachable - Fragmentation Needed packets are not handled properly for VRFs. Specifically, the FIB lookup in __ip_rt_update_pmtu fails so no nexthop exception is created with the reduced MTU. As a result connections stall if packets larger than the smallest MTU in the path are generated. While investigating that problem I also noticed that the MSS for all connections in a VRF is based on the VRF device's MTU and not the route the packets ultimately go through. VRF currently uses a dst to direct packets to the device. The first FIB lookup returns this dst and then the lookup in the VRF driver gets the actual output route. A side effect of this design is that the VRF dst is cached on sockets and then used for calculations like the MSS. This series fixes this problem by removing the hook in the FIB lookups that returns the dst pointing to the VRF device to the VRF and always doing the actual FIB lookup. This allows the real dst to be used throughout the stack (for example the MSS). Packets are diverted to the VRF device on Tx using an l3mdev hook in the output path similar to to what is done for Rx. The end result is a simpler implementation for VRF with fewer intrusions into the network stack and symmetrical packet handling for Rx and Tx paths. Comparison of netperf performance for a build without l3mdev (best case performance), the old vrf driver and the VRF driver from this series. Data are collected using VMs with virtio + vhost. The netperf client runs in the VM and netserver runs in the host. 1-byte RR tests are done as these packets exaggerate the performance hit due to the extra lookups done for l3mdev and VRF. Command: netperf -cC -H ${ip} -l 60 -t {TCP,UDP}_RR [-J red] TCP_RR UDP_RR IPv4 IPv6 IPv4 IPv6 no l3mdev 29,996 30,601 31,638 24,336 vrf old 27,417 27,626 29,159 24,801 vrf new 28,036 28,372 30,110 24,857 l3mdev, no vrf 29,534 30,465 30,670 24,346 * Transactions per second as reported by netperf * netperf modified to take a bind-to-device argument -- the -J red option 1. 'no l3mdev' == NET_L3_MASTER_DEV is unset so code is compiled out 2. 'vrf old' == data for existing implementation 3. 'vrf new' == data with this series 4. 'l3mdev, no vrf' == NET_L3_MASTER_DEV is enabled but traffic is not going through a VRF About the series - patch 1 adds the flow update (changing oif or iif to L3 master device and setting the flag to skip the oif check) to ipv4 and ipv6 paths just before hitting the rules. This catches all code paths in a single spot. - patch 2 adds the Tx hook to push the packet to the l3mdev if relevant - patch 3 adds some checks so the vrf device can act as a vrf-local loopback. These changes were not needed before since the vrf dst was returned from the lookup. - patches 4 and 5 flip the ipv4 and ipv6 stacks to the tx hook leaving the route lookup to be the real one. The dst flip happens at the beginning of the L3 output path so the VRFs can have device based features such as netfilter, tc and tcpdump. - patches 6-11 remove no longer needed l3mdev code v2 - properly handle IPv6 link scope addresses - keep the device xmit path and associated dst which is switched in by the l3_out hook. packets still need to go through the xmit path in case the user puts a qdisc on the vrf device and to allow tc rules. version 1 short circuited the tx handling and only covered netfilter and tcpdump. ==================== Signed-off-by: David S.

2016-09-10net: vrf: Flip IPv6 output path from FIB lookup hook to out hookDavid Ahern
Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in. Convert the existing vrf_get_rt6_dst to handle only link scope addresses. Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
