2018-01-09virtio_net: propagate linkspeed/duplex settings from the hypervisorJason Baron2-1/+35
The ability to set speed and duplex for virtio_net is useful in various scenarios as described here: 16032be virtio_net: add ethtool support for set and get of settings However, it would be nice to be able to set this from the hypervisor, such that virtio_net doesn't require custom guest ethtool commands. Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows the hypervisor to export a linkspeed and duplex setting. The user can subsequently overwrite it later if desired via: 'ethtool -s'. Note that VIRTIO_NET_F_SPEED_DUPLEX is defined as bit 63, the intention is that device feature bits are to grow down from bit 63, since the transports are starting from bit 24 and growing up.

2018-01-09Merge branch 'XDP-transmission-for-tuntap'David S. Miller5-90/+269
Jason Wang says: ==================== XDP transmission for tuntap This series tries to implement XDP transmission (ndo_xdp_xmit) for tuntap. Pointer ring was used for queuing both XDP buffers and sk_buff, this is done by encoding the type into lowest bit of the pointer and storin XDP metadata in the headroom of XDP buff. Tests gets 3.05 Mpps when doing xdp_redirect_map from ixgbe to VM (testpmd + virtio-net in guest). This gives us ~20% improvments compared to use skb during redirect. Please review.

2018-01-09tuntap: XDP transmissionJason Wang3-33/+208
This patch implements XDP transmission for TAP. Since we can't create new queues for TAP during XDP set, exist ptr_ring was reused for queuing XDP buffers. To differ xdp_buff from sk_buff, TUN_XDP_FLAG (0x1UL) was encoded into lowest bit of xpd_buff pointer during ptr_ring_produce, and was decoded during consuming. XDP metadata was stored in the headroom of the packet which should work in most of cases since driver usually reserve enough headroom. Very minor changes were done for vhost_net: it just need to peek the length depends on the type of pointer. Tests were done on two Intel E5-2630 2.40GHz machines connected back to back through two 82599ES. Traffic were generated/received through MoonGen/testpmd(rxonly). It reports ~20% improvements when xdp_redirect_map is doing redirection from ixgbe to TAP (from 2.50Mpps to 3.05Mpps) Cc: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree: 1) Free hooks via call_rcu to speed up netns release path, from Florian Westphal. 2) Reduce memory footprint of hook arrays, skip allocation if family is not present - useful in case decnet support is not compiled built-in. Patches from Florian Westphal. 3) Remove defensive check for malformed IPv4 - including ihl field - and IPv6 headers in x_tables and nf_tables. 4) Add generic flow table offload infrastructure for nf_tables, this includes the netlink control plane and support for IPv4, IPv6 and mixed IPv4/IPv6 dataplanes. This comes with NAT support too. This patchset adds the IPS_OFFLOAD conntrack status bit to indicate that this flow has been offloaded. 5) Add secpath matching support for nf_tables, from Florian. 6) Save some code bytes in the fast path for the nf_tables netdev, bridge and inet families. 7) Allow one single NAT hook per point and do not allow to register NAT hooks in nf_tables before the conntrack hook, patches from Florian. 8) Seven patches to remove the struct nf_af_info abstraction, instead we perform direct calls for IPv4 which is faster. IPv6 indirections are still needed to avoid dependencies with the 'ipv6' module, but these now reside in struct nf_ipv6_ops. 9) Seven patches to handle NFPROTO_INET from the Netfilter core, hence we can remove specific code in nf_tables to handle this pseudofamily. 10) No need for synchronize_net() call for nf_queue after conversion to hook arrays. Also from Florian. 11) Call cond_resched_rcu() when dumping large sets in ipset to avoid softlockup. Again from Florian. 12) Pass lockdep_nfnl_is_held() to rcu_dereference_protected(), patch from Florian Westphal. 13) Fix matching of counters in ipset, from Jozsef Kadlecsik. 14) Missing nfnl lock protection in the ip_set_net_exit path, also from Jozsef. 15) Move connlimit code that we can reuse from nf_tables into nf_conncount, from Florian Westhal. And asorted cleanups: 16) Get rid of nft_dereference(), it only has one single caller. 17) Add nft_set_is_anonymous() helper function. 18) Remove NF_ARP_FORWARD leftover chain definition in nf_tables_arp. 19) Remove unnecessary comments in nf_conntrack_h323_asn1.c From Varsha Rao. 20) Remove useless parameters in frag_safe_skb_hp(), from Gao Feng. 21) Constify layer 4 conntrack protocol definitions, function parameters to register/unregister these protocol trackers, and timeouts. Patches from Florian Westphal. 22) Remove nlattr_size indirection, from Florian Westphal. 23) Add fall-through comments as -Wimplicit-fallthrough needs this, from Gustavo A. R. Silva. 24) Use swap() macro to exchange values in ipset, patch from Gustavo A. R. Silva. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-01-08sctp: fix the handling of ICMP Frag Needed for too small MTUsMarcelo Ricardo Leitner3-13/+26
syzbot reported a hang involving SCTP, on which it kept flooding dmesg with the message: [ 246.742374] sctp: sctp_transport_update_pmtu: Reported pmtu 508 too low, using default minimum of 512 That happened because whenever SCTP hits an ICMP Frag Needed, it tries to adjust to the new MTU and triggers an immediate retransmission. But it didn't consider the fact that MTUs smaller than the SCTP minimum MTU allowed (512) would not cause the PMTU to change, and issued the retransmission anyway (thus leading to another ICMP Frag Needed, and so on). As IPv4 (ip_rt_min_pmtu=556) and IPv6 (IPV6_MIN_MTU=1280) minimum MTU are higher than that, sctp_transport_update_pmtu() is changed to re-fetch the PMTU that got set after our request, and with that, detect if there was an actual change or not. The fix, thus, skips the immediate retransmission if the received ICMP resulted in no change, in the hope that SCTP will select another path. Note: The value being used for the minimum MTU (512, SCTP_DEFAULT_MINSEGMENT) is not right and instead it should be (576, SCTP_MIN_PMTU), but such change belongs to another patch. Changes from v1: - do not disable PMTU discovery, in the light of commit 06ad391919b2 ("[SCTP] Don't disable PMTU discovery when mtu is small") and as suggested by Xin Long. - changed the way to break the rtx loop by detecting if the icmp resulted in a change or not Changes from v2: none See-also: https://lkml.org/lkml/2017/12/22/811 Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.

Currently, if PMTU discovery is disabled on a given transport, but the configured value is higher than the actual PMTU, it is likely that we will get some icmp Frag Needed. The issue is, if PMTU discovery is disabled, we won't update the information and will issue a retransmission immediately, which may very well trigger another ICMP, and another retransmission, leading to a loop. The fix is to simply not trigger immediate retransmissions if PMTU discovery is disabled on the given transport.

In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a check for "Invalid VF id". Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer.

2018-01-08tcp: Split BUG_ON() in tcp_tso_should_defer() into two assertionsStefano Brivio1-1/+2
The two conditions triggering BUG_ON() are somewhat unrelated: the tcp_skb_pcount() check is meant to catch TSO flaws, the second one checks sanity of congestion window bookkeeping. Split them into two separate BUG_ON() assertions on two lines, so that we know which one actually triggers, when they do. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: David S.

2018-01-08net: ipv6: Allow connect to linklocal address from socket bound to vrfDavid Ahern3-4/+22
Allow a process bound to a VRF to connect to a linklocal address. Currently, this fails because of a mismatch between the scope of the linklocal address and the sk_bound_dev_if inherited by the VRF binding: $ ssh -6 fe80::70b8:cff:fedd:ead8%eth1 ssh: connect to host fe80::70b8:cff:fedd:ead8%eth1 port 22: Invalid argument Relax the scope check to allow the socket to be bound to the same L3 device as the scope id. This makes ipv6 linklocal consistent with other relaxed checks enabled by commits 1ff23beebdd3 ("net: l3mdev: Allow send on enslaved interface") and 7bb387c5ab12a ("net: Allow IP_MULTICAST_IF to set index to L3 slave").

Since the commit 888cc8c20cf ("sh_eth: remove EDMAC_BIG_ENDIAN") (geez, I didn't realize that was 2 years ago!) the initializers in the SuperH platform code for the 'sh_eth_plat_data::edmac_endian' stopped to matter, so we can remove that field for good (not sure if it was ever useful -- SH7786 Ether has been reported to have the same EDMAC descriptor/register endiannes as configured for the SuperH CPU)...

Pause parameters include source address, transmit gap and pause time. The default value of the pause source address is zero in the hardware. Default pause parameters need to be set to the hardware. Also, when setting new mac address, the pause source address need to be updated.

2018-01-08net: hns3: fix for setting MTUFuyun Liang3-5/+16
When setting MTU, actually what we do is configuring the max frame size for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be considered. And the frame size which is less than the default value should not be set to the hardware. Because in the hardware, the the max frame size not only controls the RX packet size, but also controls the TX packet size. the RX packets whose size are greater than the setting value will be dropped. This patch fixes the bug setting a error max frame size to hardware.

The wrong fc_mode_last_time will be used to update flow control mode when lldpad has been running. As a result, when using the ethtool command "-a", user will get a wrong pause parameter.
