2019-02-23e1000e: Fix -Wformat-truncation warningsFlorian Fainelli
Provide precision hints to snprintf() since we know the destination buffer size of the RX/TX ring names are IFNAMSIZ + 5 - 1. This fixes the following warnings: drivers/net/ethernet/intel/e1000e/netdev.c: In function 'e1000_request_msix': drivers/net/ethernet/intel/e1000e/netdev.c:2109:13: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=] "%s-rx-0", netdev->name); ^ drivers/net/ethernet/intel/e1000e/netdev.c:2107:3: note: 'snprintf' output between 6 and 21 bytes into a destination of size 20 snprintf(adapter->rx_ring->name, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(adapter->rx_ring->name) - 1, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%s-rx-0", netdev->name); ~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/intel/e1000e/netdev.c:2125:13: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=] "%s-tx-0", netdev->name); ^ drivers/net/ethernet/intel/e1000e/netdev.c:2123:3: note: 'snprintf' output between 6 and 21 bytes into a destination of size 20 snprintf(adapter->tx_ring->name, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(adapter->tx_ring->name) - 1, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%s-tx-0", netdev->name); ~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2019-02-22net/mlx5: E-Switch, Add support for VEPA in legacy mode.Huy Nguyen
In Virtual Ethernet Port Aggregator (VEPA) mode, the packet skips the system internal virtual switch and forwards to external network switch. In Mellanox HCA case, the virtual switch is the HCA's Eswitch. To support this, an new FDB flow table are created with level 0 and linked to the existing FDB flow table in legacy mode. By default, VEPA is turned off and this FDB flow table is empty. When VEPA is turned on, two rules are created. One rule to forward on uplink vport traffic to the legacy FDB. The other rule forward all other traffic to uplink vport. Other design alternatives were not chosen as explained below: 1. Create a forward rule in ACL flow table (most efficient design). This approach is the not chosen because firmware does not support forward rule to uplink vport (0xffff) for ACL flow table. 2. Add additional source port criteria in all the FDB rules to make the FDB rules to be received rules only. This approach is not chosen because it is not efficient as there can many rules in the FDB and VEPA mode cannot be controlled per vport. 3. Add a highest prioirty flow group in the existing legacy FDB Flow Table instead of a new flow table. This approoach does not work because the new flow group has the same match criteria as the promiscuous flow group and mlx5_add_flow_rules does not allow specifying flow group.

2019-02-22net/mlx5e: Fix GRE key by controlling port tunnel entropy calculationEli Britstein
Flow entropy is calculated on the inner packet headers and used for flow distribution in processing, routing etc. For GRE-type encapsulations the entropy value is placed in the eight LSB of the key field in the GRE header as defined in NVGRE RFC 7637. For UDP based encapsulations the entropy value is placed in the source port of the UDP header. The hardware may support entropy calculation specifically for GRE and for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add GRE protocol offloading") GRE is offloaded, but the hardware is configured by default to calculate flow entropy so packets transmitted on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN), GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the hardware behaviour must be controlled by the driver. Ensure port entropy calculation is enabled for offloaded VXLAN tunnels and disable port entropy calculation in the presence of offloaded GRE tunnels by monitoring the presence of entropy enabling tunnels (i.e VXLAN) and entropy disabing tunnels (i.e GRE).

2019-02-22net: Don't set transport offset to invalid valueMaxim Mikityanskiy
If the socket was created with socket(AF_PACKET, SOCK_RAW, 0), skb->protocol will be unset, __skb_flow_dissect() will fail, and skb_probe_transport_header() will fall back to the offset_hint, making the resulting skb_transport_offset incorrect. If, however, there is no transport header in the packet, transport_header shouldn't be set to an arbitrary value. Fix it by leaving the transport offset unset if it couldn't be found, to be explicit rather than to fill it with some wrong value. It changes the behavior, but if some code relied on the old behavior, it would be broken anyway, as the old one is incorrect.

private for each of them. Having one work queue for receive mode configuration ndo_set_rx_mode() call for all VFs results in making each of them wait till the set_rx_mode() call completes for another VF if any of close, set receive mode and change flags calls being already invoked. Potentially this could cause device state change before appropriate call of receive mode configuration completes, so the call itself became meaningless, corrupt data or break configuration sequence. We don't need any delays in NIC VF configuration sequence so having delayed work call with 0 delay has no sense. This commit is to implement one work queue for each NIC VF for set_rx_mode task and to let them work independently and replacing delayed_work with work_struct.

2019-02-22ipvlan: disallow userns cap_net_admin to change global mode/flagsDaniel Borkmann
When running Docker with userns isolation e.g. --userns-remap="default" and spawning up some containers with CAP_NET_ADMIN under this realm, I noticed that link changes on ipvlan slave device inside that container can affect all devices from this ipvlan group which are in other net namespaces where the container should have no permission to make changes to, such as the init netns, for example. This effectively allows to undo ipvlan private mode and switch globally to bridge mode where slaves can communicate directly without going through hostns, or it allows to switch between global operation mode (l2/l3/l3s) for everyone bound to the given ipvlan master device. libnetwork plugin here is creating an ipvlan master and ipvlan slave in hostns and a slave each that is moved into the container's netns upon creation event. * In hostns: # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l3 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] * Spawn container & change ipvlan mode setting inside of it: # docker run -dt --cap-add=NET_ADMIN --network cilium-net --name client -l app=test cilium/netperf 9fff485d69dcb5ce37c9e33ca20a11ccafc236d690105aadbfb77e4f4170879c # docker exec -ti client ip -d a [...] 10: cilium0@if4: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l3 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever # docker exec -ti client ip link change link cilium0 name cilium0 type ipvlan mode l2 # docker exec -ti client ip -d a [...] 10: cilium0@if4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever * In hostns (mode switched to l2): # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] Same l3 -> l2 switch would also happen by creating another slave inside the container's network namespace when specifying the existing cilium0 link to derive the actual (bond0) master: # docker exec -ti client ip link add link cilium0 name cilium1 type ipvlan mode l2 # docker exec -ti client ip -d a [...] 2: cilium1@if4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 10: cilium0@if4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever * In hostns: # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] One way to mitigate it is to check CAP_NET_ADMIN permissions of the ipvlan master device's ns, and only then allow to change mode or flags for all devices bound to it.
