Eric says: "By looking at tcpdump, and TS val of xmit packets of multiple flows, we can deduct the relative qdisc delays (think of fq pacing). This should work even if we have one flow per remote peer." Having random per flow (or host) offsets doesn't allow that anymore so add a way to turn this off.

jiffies based timestamps allow for easy inference of number of devices behind NAT translators and also makes tracking of hosts simpler. commit ceaa1fef ("tcp: adding a per-socket timestamp offset") added the main infrastructure that is needed for per-connection ts randomization, in particular writing/reading the on-wire tcp header format takes the offset into account so rest of stack can use normal tcp_time_stamp (jiffies). So only two items are left: - add a tsoffset for request sockets - extend the tcp isn generator to also return another 32bit number in addition to the ISN. Re-use of ISN generator also means timestamps are still monotonically increasing for same connection quadruple, i.e. PAWS will still work. Includes fixes from Eric Dumazet.

Manish Rangankar says: ==================== Add QLogic FastLinQ iSCSI (qedi) driver. This series introduces hardware offload iSCSI initiator driver for the 41000 Series Converged Network Adapters (579xx chip) by Qlogic. The overall driver design includes a common module ('qed') and protocol specific dependent modules ('qedi' for iSCSI). This is an open iSCSI driver, modifications to open iSCSI user components 'iscsid', 'iscsiuio', etc. are required for the solution to work. The user space changes are also in the process of being submitted. https://groups.google.com/forum/#!forum/open-iscsi The 'qed' common module, under drivers/net/ethernet/qlogic/qed/, is enhanced with functionality required for the iSCSI support. This series is based on: net tree base: Merge of net and net-next as of 11/29/2016 Changes from RFC v2: 1. qedi patches are squashed into single patch to prevent krobot warning. 2. Fixed 'hw_p_cpuq' incompatible pointer type. 3. Fixed sparse incompatible types in comparison expression. 4. Misc fixes with latest 'checkpatch --strict' option. 5. Remove int_mode option from MODULE_PARAM. 6. Prefix all MODULE_PARAM params with qedi_*. 7. Use CONFIG_QED_ISCSI instead of CONFIG_QEDI 8.

After 326fe02d ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"), the rcu_read_lock() in bpf_prog_run_xdp() is superfluous, since callers need to hold rcu_read_lock() already to make sure BPF program doesn't get released in the background. Thus, drop it from bpf_prog_run_xdp(), as it can otherwise be misleading. Still keeping the bpf_prog_run_xdp() is useful as it allows for grepping in XDP supported drivers and to keep the typecheck on the context intact. For mlx4, this means we don't have a double rcu_read_lock() anymore. nfp can just make use of bpf_prog_run_xdp(), too. For qede, just move rcu_read_lock() out of the helper. When the driver gets atomic replace support, this will move to call-sites eventually. mlx5 needs actual fixing as it has the same issue as described already in 326fe02d ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"), that is, we're under RCU bh at this time, BPF programs are released via call_rcu(), and call_rcu() != call_rcu_bh(), so we need to properly mark read side as programs can get xchg()'ed in mlx5e_xdp_set() without queue reset.

Only when ICMP packets are enqueued onto the error queue, sk_err is also set. Before f5f99309 (sock: do not set sk_err in sock_dequeue_err_skb), a subsequent error queue read would set sk_err to the next error on the queue, or 0 if empty. As no error types other than ICMP set this field, sk_err should not be modified upon dequeuing them. Only for ICMP errors, reset the (racy) sk_err. Some applications, like traceroute, rely on it and go into a futile busy POLLERR loop otherwise. In principle, sk_err has to be set while an ICMP error is queued. Testing is_icmp_err_skb(skb_next) approximates this without requiring a full queue walk. Applications that receive both ICMP and other errors cannot rely on this legacy behavior, as other errors do not set sk_err in the first place.

Thomas Graf says: ==================== bpf: BPF for lightweight tunnel encapsulation This series implements BPF program invocation from dst entries via the lightweight tunnels infrastructure. The BPF program can be attached to lwtunnel_input(), lwtunnel_output() or lwtunnel_xmit() and see an L3 skb as context. Programs attached to input and output are read-only. Programs attached to lwtunnel_xmit() can modify and redirect, push headers and redirect packets. The facility can be used to: - Collect statistics and generate sampling data for a subset of traffic based on the dst utilized by the packet thus allowing to extend the existing realms. - Apply additional per route/dst filters to prohibit certain outgoing or incoming packets based on BPF filters. In particular, this allows to maintain per dst custom state across multiple packets in BPF maps and apply filters based on statistics and behaviour observed over time. - Attachment of L2 headers at transmit where resolving the L2 address is not required. - Possibly many more. v3 -> v4: - Bumped LWT_BPF_MAX_HEADROOM from 128 to 256 (Alexei) - Renamed bpf_skb_push() helper to bpf_skb_change_head() to relate to existing bpf_skb_change_tail() helper (Alexei/Daniel) - Added check in __bpf_redirect_common() to verify that program added a link header before redirecting to a l2 device. Adding the check to lwt-bpf code was considered but dropped due to massive code required due to retrieval of net_device via per-cpu redirect buffer. A test case was added to cover the scenario when a program directs to an l2 device without adding an appropriate l2 header. (Alexei) - Prohibited access to tc_classid (Daniel) - Collapsed bpf_verifier_ops instance for lwt in/out as they are identical (Daniel) - Some cosmetic changes v2 -> v3: - Added real world sample lwt_len_hist_kern.c which demonstrates how to collect a histogram on packet sizes for all packets flowing through a number of routes. - Restricted output to be read-only. Since the header can no longer be modified, the rerouting functionality has been removed again. - Added test case which cover destructive modification of packet data. v1 -> v2: - Added new BPF_LWT_REROUTE return code for program to indicate that new route lookup should be performed. Suggested by Tom. - New sample to illustrate rerouting - New patch 05: Recursion limit for lwtunnel_output for the case when user creates circular dst redirection.

Registers new BPF program types which correspond to the LWT hooks: - BPF_PROG_TYPE_LWT_IN => dst_input() - BPF_PROG_TYPE_LWT_OUT => dst_output() - BPF_PROG_TYPE_LWT_XMIT => lwtunnel_xmit() The separate program types are required to differentiate between the capabilities each LWT hook allows: * Programs attached to dst_input() or dst_output() are restricted and may only read the data of an skb. This prevent modification and possible invalidation of already validated packet headers on receive and the construction of illegal headers while the IP headers are still being assembled. * Programs attached to lwtunnel_xmit() are allowed to modify packet content as well as prepending an L2 header via a newly introduced helper bpf_skb_change_head(). This is safe as lwtunnel_xmit() is invoked after the IP header has been assembled completely. All BPF programs receive an skb with L3 headers attached and may return one of the following error codes: BPF_OK - Continue routing as per nexthop BPF_DROP - Drop skb and return EPERM BPF_REDIRECT - Redirect skb to device as per redirect() helper. (Only valid in lwtunnel_xmit() context) The return codes are binary compatible with their TC_ACT_ relatives to ease compatibility.

A route on the output path hitting a RTN_LOCAL route will keep the dst associated on its way through the loopback device. On the receive path, the dst_input() call will thus invoke the input handler of the route created in the output path. Thus, lwt redirection for input must be done for dsts allocated in the otuput path as well. Also, if a route is cached in the input path, the allocated dst should respect lwtunnel configuration on the nexthop as well. Signed-off-by: NThomas Graf <tgraf@suug.ch> Signed-off-by: NDavid S.

由 Neill Whillans 提交于
Add support for the (optional) SGMII PCS functionality of the Altera TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover and initialise the PCS so that the MAC can communicate to the PHY. The PCS IP block provides a scratch register for testing presence of the PCS, which is mapped into one of the two MDIO spaces present in the MAC's register space. Once we have determined that the scratch register is functioning, we attempt to initialise the PCS to auto-negotiate an SGMII link with the PHY. There is no need to monitor or manage the SGMII link beyond this, since the normal PHY MDIO will then be used to monitor the media layer. The Altera TSE MAC has only one way in which it can be configured with an SGMII PCS, and as such, this patch only looks to the phy-mode to select whether or not to attempt to initialise the PCS registers. During initialisation, we report the PCS's equivalent of a PHY ID register. This can be parameterised during the IP instantiation and is often left as '0x00000000' which is not an error.

To connect two ports of the same configuration (MDI to MDI or MDI-X to MDI-X) with a 10/100/1000 Mbit/s connection, an Ethernet crossover cable is needed to cross over the transmit and receive signals in the cable, so that they are matched at the connector level. When connecting an MDI port to an MDI-X port a straight through cable is used while to connect two MDI ports or two MDI-X ports a crossover cable must be used. Conventionally MDI is used on end devices while MDI-X is used on hubs and switches Auto MDI-X automatically detects the required cable connection type and configures the connection appropriately, removing the need for crossover cables to interconnect switches or connecting PCs peer-to-peer.
