After we move cached dst entries into the exception table under its parent route, current fib6_remove_prefsrc() no longer can access them. This commit makes fib6_remove_prefsrc() also go through all routes in the exception table to remove the pref src. This is a preparation patch in order to move all cached dst into the exception table.

Add a hash table into struct rt6_info in order to store dst caches created by pmtu discovery and ip redirect in ipv6 routing code. APIs to add dst cache, delete dst cache, find dst cache and update dst cache in the hash table are implemented and will be used in later commits.

Using a linear list to store all skbs in write queue has been okay for quite a while : O(N) is not too bad when N < 500. Things get messy when N is the order of 100,000 : Modern TCP stacks want 10Gbit+ of throughput even with 200 ms RTT flows. 40 ns per cache line miss means a full scan can use 4 ms, blowing away CPU caches. SACK processing often can use various hints to avoid parsing whole retransmit queue. But with high packet losses and/or high reordering, hints no longer work. Sender has to process thousands of unfriendly SACK, accumulating a huge socket backlog, burning a cpu and massively dropping packets. Using an rb-tree for retransmit queue has been avoided for years because it added complexity and overhead, but now is the time to be more resistant and say no to quadratic behavior. 1) RTX queue is no longer part of the write queue : already sent skbs are stored in one rb-tree. 2) Since reaching the head of write queue no longer needs sk->sk_send_head, we added an union of sk_send_head and tcp_rtx_queue Tested: On receiver : netem on ingress : delay 150ms 200us loss 1 GRO disabled to force stress and SACK storms. for f in `seq 1 10` do ./netperf -H lpaa6 -l30 -- -K bbr -o THROUGHPUT|tail -1 done | awk '{print $0} {sum += $0} END {printf "%7u\n",sum}' Before patch : 323.87 351.48 339.59 338.62 306.72 204.07 304.93 291.88 202.47 176.88 2840 After patch: 1700.83 2207.98 2070.17 1544.26 2114.76 2124.89 1693.14 1080.91 2216.82 1299.94 18053 Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-10-06 This series contains updates to i40e and i40evf only. Rami fixes a typo in the code comments. Mitch adds an ethtool private flag to control source pruning to resolve an issue where our default behavior is to enable source pruning which breaks ARP monitoring in channel bonding. Fixes a couple of register definitions, which were incorrect. Jake fixes an issue with multiple logical CPUs per core (simultaneous multithreading - SMT) and how we set an affinity hint based on the v_idx of that q_vector, which is an incremental value and might lead to multiple offline CPUs being assigned to a q_vector. Instead, we should only assign hints for CPUs which are online, so look to use cpumask_local_spread(). Also fixed a VF VLAN tag stripping issue, where the flag created to change this feature was seen as unchangeable. Lastly, organized and re-numbered the feature flags. Alan re-enables PTP L4 for XL710 devices with firmware version 6.0 or greater, now that the previous bug in the older firmware is fixed. Implements the PCI error handlers for reset_prepare() and reset_done() to allow us to handle function level resets. Alice cleans up code that was added to the incorrect function during a merge. Filip adds a change to display an error message when a module is inserted that does not meet the thermal requirements, Talking Heads "Burning Down the House" comes to mind. Also fixed a flow director filter issue where a variable was not being cleared which stores the filter number to be removed from the list when the firmware refused to add the requested filter. ==================== Signed-off-by: NDavid S.

This is useful for distinguishing intentional (XDP_DROP) vs. ebpf-program error cases that cased a drop (XDP_ABORTED).

Now that we've reduced the number of flags, organize similar flags together and re-number them accordingly. Since we don't yet have more than 32 flags, we'll use a u32 for both the hw_features and flag field. Should we gain more flags in the future, we may need to convert to a u64 or separate flags out into two fields. One alternative approach considered, but not implemented here, was to use an enumeration for the flag variables, and create a macro I40E_FLAG() which used string concatenation to generate BIT_ULL values. This has the advantage of making the actual bit values compile-time dynamic so that we do not need to worry about matching the order to the bit value. However, this does produce a high level of code churn, and makes it more difficult to read a dumped flags value when debugging.

Since commit 6a7fded7 ("i40e: Fix RS bit update in Tx path and disable force WB workaround") we've tried to "optimize" setting the RS bit based around skb->xmit_more. This same logic was refactored in commit 1dc8b538 ("i40e: Reorder logic for coalescing RS bits"), but ultimately was not functionally changed. Using skb->xmit_more in this way is incorrect, because in certain circumstances we may see a large number of skbs in sequence with xmit_more set. This leads to a performance loss as the hardware does not writeback anything for those packets, which delays the time it takes for us to respond to the stack transmit requests. This significantly impacts UDP performance, especially when layered with multiple devices, such as bonding, VLANs, and vnet setups. This was not noticed until now because it is difficult to create a setup which reproduces the issue. It was discovered in a UDP_STREAM test in a VM, connected using a vnet device to a bridge, which is connected to a bonded pair of X710 ports in active-backup mode with a VLAN. These layered devices seem to compound the number of skbs transmitted at once by the qdisc. Additionally, the problem can be masked by reducing the ITR value. Since the original commit does not provide strong justification for this RS bit "optimization", revert to the previous behavior of setting the RS bit every 4th packet.

A recent commit 809481484e5d ("i40e/i40evf: support for VF VLAN tag stripping control") added support for VFs to negotiate the control of VLAN tag stripping. This should have allowed VFs to disable the feature. Unfortunately, the flag was set only in netdev->feature flags and not in netdev->hw_features. This ultimately causes the stack to assume that it cannot change the flag, so it was unchangeable and marked as [fixed] in the ethtool -k output. Fix this by setting the feature in hw_features first, just as we do for the PF code. This enables ethtool -K to disable the feature correctly, and fully enables user control of the VLAN tag stripping feature.

When there is no space for more flow director filters and user requested to add a new one it is rejected by firmware and automatically removed from the filter list maintained by driver. This behaviour is correct. Afterwards existing filter can be removed making free slot for the new one. This however causes the newly added filter to be accepted by firmware but removed from driver filter list resulting in not showing after issuing 'ethtool -n <dev_name>'. This happened due to not clearing the variable pf->fd_inv which stores filter number to be removed from the list when firmware refused to add the requested filter. It caused the filter with this specific ID to be constantly removed once it was added to the list although it has been accepted by firmware and effectively applied to the NIC. It was fixed by clearing pf->fd_inv variable after removal of the filter from the list when it was rejected by firmware.
