2018-11-01netfilter: ipset: actually allow allowable CIDR 0 in hash:net,port,netEric Westbrook1-4/+4
Allow /0 as advertised for hash:net,port,net sets. For "hash:net,port,net", ipset(8) says that "either subnet is permitted to be a /0 should you wish to match port between all destinations." Make that statement true. Before: # ipset create cidrzero hash:net,port,net # ipset add cidrzero 0.0.0.0/0,12345,0.0.0.0/0 ipset v6.34: The value of the CIDR parameter of the IP address is invalid # ipset create cidrzero6 hash:net,port,net family inet6 # ipset add cidrzero6 ::/0,12345,::/0 ipset v6.34: The value of the CIDR parameter of the IP address is invalid After: # ipset create cidrzero hash:net,port,net # ipset add cidrzero 0.0.0.0/0,12345,0.0.0.0/0 # ipset test cidrzero 192.168.205.129,12345,172.16.205.129 192.168.205.129,tcp:12345,172.16.205.129 is in set cidrzero. # ipset create cidrzero6 hash:net,port,net family inet6 # ipset add cidrzero6 ::/0,12345,::/0 # ipset test cidrzero6 fe80::1,12345,ff00::1 fe80::1,tcp:12345,ff00::1 is in set cidrzero6.

2018-11-01netfilter: ipset: list:set: Decrease refcount synchronously on deletion and replaceStefano Brivio3-19/+23
Commit 45040978c899 ("netfilter: ipset: Fix set:list type crash when flush/dump set in parallel") postponed decreasing set reference counters to the RCU callback. An 'ipset del' command can terminate before the RCU grace period is elapsed, and if sets are listed before then, the reference counter shown in userspace will be wrong: # ipset create h hash:ip; ipset create l list:set; ipset add l # ipset del l h; ipset list h Name: h Type: hash:ip Revision: 4 Header: family inet hashsize 1024 maxelem 65536 Size in memory: 88 References: 1 Number of entries: 0 Members: # sleep 1; ipset list h Name: h Type: hash:ip Revision: 4 Header: family inet hashsize 1024 maxelem 65536 Size in memory: 88 References: 0 Number of entries: 0 Members: Fix this by making the reference count update synchronous again. As a result, when sets are listed, ip_set_name_byindex() might now fetch a set whose reference count is already zero. Instead of relying on the reference count to protect against concurrent set renaming, grab ip_set_ref_lock as reader and copy the name, while holding the same lock in ip_set_rename() as writer instead.

2018-10-24net/ipv6: Allow onlink routes to have a device mismatch if it is the default routeDavid Ahern2-7/+9
The intent of ip6_route_check_nh_onlink is to make sure the gateway given for an onlink route is not actually on a connected route for a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway lookup hits the default route then it most likely will be a different interface than the onlink route which is ok. Update ip6_route_check_nh_onlink to disregard the device mismatch if the gateway lookup hits the default route. Turns out the existing onlink tests are passing because there is no default route or it is an unreachable default, so update the onlink tests to have a default route other than unreachable.

2018-10-24ice: Poll for link status changeAnirudh Venkataramanan3-120/+25
When the physical link goes up or down, the driver is supposed to receive a link status event (LSE). The driver currently has the code to handle LSEs but there is no firmware support for this feature yet. So this patch adds the ability for the driver to poll for link status changes. The polling itself is done in ice_watchdog_subtask. For namespace cleanliness, this patch also removes code that handles LSE. This code will be reintroduced once the feature is officially supported.

2018-10-24net: udp: fix handling of CHECKSUM_COMPLETE packetsSean Tranchetti3-6/+39
Current handling of CHECKSUM_COMPLETE packets by the UDP stack is incorrect for any packet that has an incorrect checksum value. udp4/6_csum_init() will both make a call to __skb_checksum_validate_complete() to initialize/validate the csum field when receiving a CHECKSUM_COMPLETE packet. When this packet fails validation, skb->csum will be overwritten with the pseudoheader checksum so the packet can be fully validated by software, but the skb->ip_summed value will be left as CHECKSUM_COMPLETE so that way the stack can later warn the user about their hardware spewing bad checksums. Unfortunately, leaving the SKB in this state can cause problems later on in the checksum calculation. Since the the packet is still marked as CHECKSUM_COMPLETE, udp_csum_pull_header() will SUBTRACT the checksum of the UDP header from skb->csum instead of adding it, leaving us with a garbage value in that field. Once we try to copy the packet to userspace in the udp4/6_recvmsg(), we'll make a call to skb_copy_and_csum_datagram_msg() to checksum the packet data and add it in the garbage skb->csum value to perform our final validation check. Since the value we're validating is not the proper checksum, it's possible that the folded value could come out to 0, causing us not to drop the packet. Instead, we believe that the packet was checksummed incorrectly by hardware since skb->ip_summed is still CHECKSUM_COMPLETE, and we attempt to warn the user with netdev_rx_csum_fault(skb->dev); Unfortunately, since this is the UDP path, skb->dev has been overwritten by skb->dev_scratch and is no longer a valid pointer, so we end up reading invalid memory. This patch addresses this problem in two ways: 1) Do not use the dev pointer when calling netdev_rx_csum_fault() from skb_copy_and_csum_datagram_msg(). Since this gets called from the UDP path where skb->dev has been overwritten, we have no way of knowing if the pointer is still valid. Also for the sake of consistency with the other uses of netdev_rx_csum_fault(), don't attempt to call it if the packet was checksummed by software. 2) Add better CHECKSUM_COMPLETE handling to udp4/6_csum_init(). If we receive a packet that's CHECKSUM_COMPLETE that fails verification (i.e. skb->csum_valid == 0), check who performed the calculation. It's possible that the checksum was done in software by the network stack earlier (such as Netfilter's CONNTRACK module), and if that says the checksum is bad, we can drop the packet immediately instead of waiting until we try and copy it to userspace. Otherwise, we need to mark the SKB as CHECKSUM_NONE, since the skb->csum field no longer contains the full packet checksum after the call to __skb_checksum_validate_complete().

2018-10-23tcp: add tcp_reset_xmit_timer() helperEric Dumazet3-15/+41
With EDT model, SRTT no longer is inflated by pacing delays. This means that RTO and some other xmit timers might be setup incorrectly. This is particularly visible with either : - Very small enforced pacing rates (SO_MAX_PACING_RATE) - Reduced rto (from the default 200 ms) This can lead to TCP flows aborts in the worst case, or spurious retransmits in other cases. For example, this session gets far more throughput than the requested 80kbit : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 2.66 With the fix : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 0.12 EDT allows for better control of rtx timers, since TCP has a better idea of the earliest departure time of each skb in the rtx queue.

Whenever the SMC connection can not be established this TCP socket is used as a fallback. All socket operations on the SMC socket are then forwarded to the TCP socket. In case of poll, the file->private_data pointer references the SMC socket because the TCP socket has no file assigned. This causes tcp_poll to wait on the wrong socket.

There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E.

But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.

After flushing all mcast entries from the table, the ones contained in mc list of ndev are not restored when promisc mode is toggled off, because they are considered as synched with ALE, thus, in order to restore them after promisc mode - reset syncing info. This fix touches only switch mode devices, including single port boards like Beagle Bone.

2018-10-22octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modesSunil Goutham4-1/+105
By default NIXLF is set in UCAST mode. This patch adds a new mailbox message which when sent by a RVU PF changes this default mode. When promiscuous mode is needed, the reserved promisc entry for each of RVU PF is setup to match against ingress channel number only, so that all pkts on that channel are accepted and forwarded to the mode change requesting PF_FUNC's NIXLF. PROMISC and ALLMULTI modes are supported only for PFs, for VFs only UCAST mode is supported. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-22octeontx2-af: Support for changing RSS algorithmSunil Goutham4-1/+108
This patch adds support for a RVU PF/VF to change NIX Rx flowkey algorithm index in NPC RX RSS_ACTION. eg: a ethtool command changing RSS algorithm for a netdev interface would trigger this change in NPC. If PF/VF doesn't specify any MCAM entry index then default UCAST entry of the NIXLF attached to PF/VF will be updated with RSS_ACTION and flowkey index.

2018-10-22octeontx2-af: NIX Rx flowkey configuration for RSSSunil Goutham3-0/+187
Configure NIX RX flowkey algorithm configuration to support RSS (receive side scaling). Currently support for only L3/L4 2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added. HW supports upto 32 different flowkey algorithms which SW can define, this patch defines 9. NPC RX ACTION has to point to one of these flowkey indices for RSS to work. The configuration is dependent on NPC parse result's layer info. So if NPC KPU profile changes suchthat LID/LTYPE values of above said protocols change then this configuration will most likely be effected.

2018-10-22octeontx2-af: NPC MCAM and LDATA extract minimal configurationSunil Goutham4-0/+181
This patch adds some minimal configuration for NPC MCAM and LDATA extraction which is sufficient enough to install ucast/bcast/promiscuous forwarding rules. Below is the config done - LDATA extraction config to extract DMAC from pkt to offset 64bit in MCAM search key. - Set MCAM lookup keysize to 224bits - Set MCAM TX miss action to UCAST_DEFAULT - Set MCAM RX miss action to DROP Also inorder to have guaranteed space in MCAM to install ucast forwarding rule for each of RVU PF/VF, reserved one MCAM entry for each of NIXLF for ucast rule. And two entries for each of RVU PF. One for bcast pkt replication and other for promiscuous mode which allows all pkts received on a HW CGX/LBK channel.

2018-10-22octeontx2-af: Enable packet length and csum validationSunil Goutham2-0/+28
Config NPC layer info from KPU profile into protocol checker to identify outer L2/IPv4/TCP/UDP headers in a packet. And enable IPv4 checksum validation. L3/L4 and L4 CSUM validation will be enabled by PF/VF drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox i.e 'nix_lf_alloc_req->rx_cfg' Also enable setting of NPC_RESULT_S[L2B] when an outer L2 broadcast address is detected.

2018-10-22octeontx2-af: Add NPC KPU profileHao Zheng2-0/+5852
NPC block is responsible for parsing and forwarding packets to different NIXLFs. NPC has 16 KPU engines (Kangaroo parse engine) and one iKPU which represents pkinds. Each physical port either CGX/LBK is assigned a pkind and upon receiving a packet HW takes that port's pkind and starts parsing as per the KPU engines config. This patch adds header files which contain configuration profile/array for each of the iKPU and 16 KPU engines.

2018-10-22octeontx2-af: NIX Tx scheduler queue config supportSunil Goutham5-5/+199
This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured.
