2018-11-08net: socionext: different approach on DMAIlias Apalodimas1-99/+128
Current driver dynamically allocates an skb and maps it as DMA Rx buffer. In order to prepare for upcoming XDP changes, let's introduce a different allocation scheme. Buffers are allocated dynamically and mapped into hardware. During the Rx operation the driver uses build_skb() to produce the necessary buffers for the network stack. This change increases performance ~15% on 64b packets with smmu disabled and ~5% with smmu enabled Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.

2018-11-08net: qca_spi: Add available buffer space verificationStefan Wahren3-1/+17
Interferences on the SPI line could distort the response of available buffer space. So at least we should check that the response doesn't exceed the maximum available buffer space. In error case increase a new error counter and retry it later. This behavior avoids buffer errors in the QCA7000, which results in an unnecessary chip reset including packet loss.

2018-11-08sock: Reset dst when changing sk_mark via setsockoptDavid Barmann1-2/+4
When setting the SO_MARK socket option, if the mark changes, the dst needs to be reset so that a new route lookup is performed. This fixes the case where an application wants to change routing by setting a new sk_mark. If this is done after some packets have already been sent, the dst is cached and has no effect.

2018-11-08s390/qeth: don't process hsuid in qeth_l3_setup_netdev()Julian Wiedmann1-3/+0
qeth_l3_setup_netdev() checks if the hsuid attribute is set on the qeth device, and propagates it to the net_device. In the past this was needed to pick up any hsuid that was set before allocation of the net_device. With commit d3d1b205e89f ("s390/qeth: allocate netdevice early") this is no longer necessary, qeth_l3_dev_hsuid_store() always stores the hsuid straight into dev->perm_addr.

2018-11-08s390/qeth: remove unused fallback in Layer3's MAC codeJulian Wiedmann1-3/+0
If the CREATE ADDR sent by qeth_l3_iqd_read_initial_mac() fails, its callback sets a random MAC address on the net_device. The error then propagates back, and qeth_l3_setup_netdev() bails out without registering the net_device. Any subsequent call to qeth_l3_setup_netdev() will then attempt a fresh CREATE ADDR which either 1) also fails, or 2) sets a proper MAC address on the net_device. Consequently, the net_device will never be registered with a random MAC and we can drop the fallback code. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

2018-11-08s390/qeth: utilize virtual MAC for Layer2 OSD devicesJulian Wiedmann4-22/+26
By default, READ MAC on a Layer2 OSD device returns the adapter's burnt-in MAC address. Given the default scenario of many virtual devices on the same adapter, qeth can't make any use of this address and therefore skips the READ MAC call for this device type. But in some configurations, the READ MAC command for a Layer2 OSD device actually returns a pre-provisioned, virtual MAC address. So enable the READ MAC code to detect this situation, and let the L2 subdriver call READ MAC for OSD devices. This also removes the QETH_LAYER2_MAC_READ flag, which protects L2 devices against calling READ MAC multiple times. Instead protect the whole call to qeth_l2_request_initial_mac().

2018-11-08fou, fou6: ICMP error handlers for FoU and GUEStefano Brivio3-0/+143
As the destination port in FoU and GUE receiving sockets doesn't necessarily match the remote destination port, we can't associate errors to the encapsulating tunnels with a socket lookup -- we need to blindly try them instead. This means we don't even know if we are handling errors for FoU or GUE without digging into the packets. Hence, implement a single handler for both, one for IPv4 and one for IPv6, that will check whether the packet that generated the ICMP error used a direct IP encapsulation or if it had a GUE header, and send the error to the matching protocol handler, if any.

2018-11-08udp: Support for error handlers of tunnels with arbitrary destination portStefano Brivio4-35/+113
ICMP error handling is currently not possible for UDP tunnels not employing a receiving socket with local destination port matching the remote one, because we have no way to look them up. Add an err_handler tunnel encapsulation operation that can be exported by tunnels in order to pass the error to the protocol implementing the encapsulation. We can't easily use a lookup function as we did for VXLAN and GENEVE, as protocol error handlers, which would be in turn called by implementations of this new operation, handle the errors themselves, together with the tunnel lookup. Without a socket, we can't be sure which encapsulation error handler is the appropriate one: encapsulation handlers (the ones for FoU and GUE introduced in the next patch, e.g.) will need to check the new error codes returned by protocol handlers to figure out if errors match the given encapsulation, and, in turn, report this error back, so that we can try all of them in __udp{4,6}_lib_err_encap_no_sk() until we have a match. v2: - Name all arguments in err_handler prototypes (David Miller) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2018-11-08net: Convert protocol error handlers from void to intStefano Brivio27-121/+177
We'll need this to handle ICMP errors for tunnels without a sending socket (i.e. FoU and GUE). There, we might have to look up different types of IP tunnels, registered as network protocols, before we get a match, so we want this for the error handlers of IPPROTO_IPIP and IPPROTO_IPV6 in both inet_protos and inet6_protos. These error codes will be used in the next patch. For consistency, return sensible error codes in protocol error handlers whenever handlers can't handle errors because, even if valid, they don't match a protocol or any of its states. This has no effect on existing error handling paths. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2018-11-08geneve: Allow configuration of DF behaviourStefano Brivio2-8/+56
draft-ietf-nvo3-geneve-08 says: It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191], [RFC1981]) be used by setting the DF bit in the IP header when Geneve packets are transmitted over IPv4 (this is the default with IPv6). Now that ICMP error handling is working for GENEVE, we can comply with this recommendation. Make this configurable, though, to avoid breaking existing setups. By default, DF won't be set. It can be set or inherited from inner IPv4 packets. If it's configured to be inherited and we are encapsulating IPv6, it will be set. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, apply DF setting only if (!geneve->collect_md) in geneve_xmit_skb() (Stephen Hemminger) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2018-11-08vxlan: Allow configuration of DF behaviourStefano Brivio3-1/+38
Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its value from the IPv4 inner header. If the encapsulated protocol is IPv6 and DF is configured to be inherited, always set it. For IPv4, inheriting DF from the inner header was probably intended from the very beginning judging by the comment to vxlan_xmit(), but it wasn't actually implemented -- also because it would have done more harm than good, without handling for ICMP Fragmentation Needed messages. According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe PMTUD implementation, says that "is a MUST that Vxlan gateways [...] SHOULD set the DF-bit [...]", whatever that means. Given this background, the only sane option is probably to let the user decide, and keep the current behaviour as default. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, move DF setting to if (!info) block in vxlan_xmit_one() (Stephen Hemminger) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2018-11-08udp: Handle ICMP errors for tunnels with same destination port on both endpointsStefano Brivio5-20/+153
For both IPv4 and IPv6, if we can't match errors to a socket, try tunnels before ignoring them. Look up a socket with the original source and destination ports as found in the UDP packet inside the ICMP payload, this will work for tunnels that force the same destination port for both endpoints, i.e. VXLAN and GENEVE. Actually, lwtunnels could break this assumption if they are configured by an external control plane to have different destination ports on the endpoints: in this case, we won't be able to trace ICMP messages back to them. For IPv6 redirect messages, call ip6_redirect() directly with the output interface argument set to the interface we received the packet from (as it's the very interface we should build the exception on), otherwise the new nexthop will be rejected. There's no such need for IPv4. Tunnels can now export an encap_err_lookup() operation that indicates a match. Pass the packet to the lookup function, and if the tunnel driver reports a matching association, continue with regular ICMP error handling. v2: - Added newline between network and transport header sets in __udp{4,6}_lib_err_encap() (David Miller) - Removed redundant skb_reset_network_header(skb); in __udp4_lib_err_encap() - Removed redundant reassignment of iph in __udp4_lib_err_encap() (Sabrina Dubroca) - Edited comment to __udp{4,6}_lib_err_encap() to reflect the fact this won't work with lwtunnels configured to use asymmetric ports.
