Move dissection of tunnel info to outside of the main flow dissection function, __skb_flow_dissect(). The sole user of this feature, the flower classifier, is updated to call tunnel info dissection directly, using skb_flow_dissect_tunnel_info(). This results in a slightly less complex implementation of __skb_flow_dissect(), in particular removing logic from that call path which is not used by the majority of users. The expense of this is borne by the flower classifier which now has to make an extra call for tunnel info dissection. This patch should not result in any behavioural change.

Salil Mehta says: ==================== net: hns3: Refactors "reset" handling code in HCLGE layer of HNS3 driver This patch refactors the code of the reset feature in HCLGE layer of HNS3 PF driver. Prime motivation to do this change is: 1. To reduce the time for which common miscellaneous Vector 0 interrupt is disabled because of the reset. Simplification of the common miscellaneous interrupt handler routine(for Vector 0) used to handle reset and other sources of Vector 0 interrupt. 2. Separate the task for handling the reset 3. Simplification of reset request submission and pending reset logic. To achieve above below few things have been done: 1. Interrupt is disabled while common miscellaneous interrupt handler is entered and re-enabled before it is exit. This reduces the interrupt handling latency as compared to older interrupt handling scheme where interrupt was being disabled in interrupt handler context and re-enabled in task context some time later. Made Miscellaneous interrupt handler more generic to handle all sources including reset interrupt source. 2. New reset service task has been introduced to service the reset handling. 3. Introduces new reset service task for honoring software reset requests like from network stack related to timeout and serving the pending reset request(to reset the driver and associated clients).

In exisiting code, the way to detect if driver/client reset should be executed or if hardware should be be soft resetted was overly complex. Existing code use to read the interrupt status register from task context to figure out if the interrupt source event was reset and then use clear the interrupt source for reset while waiting for the hardware to finish the reset. This behaviour again was confusing and overly complex in terms of the flow. This patch simplifies the handling of the requested reset and the pending reset(i.e. reset which have already been asserted by the software and hardware has acknowledged back to driver that it is processing the hardware reset through interrupt) Signed-off-by: NSalil Mehta <salil.mehta@huawei.com> Signed-off-by: Nlipeng <lipeng321@huawei.com> Signed-off-by: NDavid S.

Existing common service task was being used to service the reset requests. This patch tries to make the handling of reset cleaner by separating task to handle the reset requests. This might in turn help in adapting similar handling approach for other interrupt events like mailbox, sharing vector 0 interrupt.

The reset interrupt event shares common miscellaneous interrupt Vector 0. In the existing reset interrupt handling we disable the Vector 0 interrupt in misc interrupt handler and re-enable them later in context to common service task. This also means other event sources like mailbox would also be deferred or if the interrupt event was due to mailbox(which shall be supported for VF soon), it could delay the reset handling. This patch reorganizes the reset interrupt handling logic and makes it more fair to other events.

Russell King says: ==================== SFP/phylink updates This series, which follows on from the fixes posted earlier, improves the phylink/sfp support. Changes included here are: - Merge 802.3z and SGMII modes into one "in-band" mode, using the PHY_INTERFACE_MODE_xxx definition to determine which should be used. This allows more flexibility as more interface modes become available. - Allow 2500base-X and 10GBASE-KR to be requested from SFP. - Remove unused and unnecessary phylink_init_eee() - Restart 802.3z autonegotiation when starting the network device to ensure that the negotiated parameters are always correct. It has been observed on mvneta that this is not always the case without this change. - Add kerneldoc documentation for phylink and sfp upstream facing APIs and link it in to the networking documentation. - Resolve a sparse warning in sfp-bus.c - Convert phylink/sfp to use fwnode rather than DT so that other firmware systems can take advantage of this - I have received a request for it to be usable with ACPI. The exception to this is our interactions with phylib, as phylib itself does not yet support fwnode. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The chip family of TILEPro and TILE-Gx was developed by Tilera, which was eventually acquired by Mellanox. The tile architecture was added to the kernel in 2010 and first appeared in 2.6.36. Now at Mellanox we are developing new chips based on the ARM64 architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and our customers using tile architecture products are not, as far as we know, looking to upgrade to newer kernel releases. In the absence of someone in the community stepping up to take over maintainership, this commit marks the architecture as orphaned.

Daniel Borkmann says: ==================== pull-request: bpf-next 2017-12-03 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Addition of a software model for BPF offloads in order to ease testing code changes in that area and make semantics more clear. This is implemented in a new driver called netdevsim, which can later also be extended for other offloads. SR-IOV support is added as well to netdevsim. BPF kernel selftests for offloading are added so we can track basic functionality as well as exercising all corner cases around BPF offloading, from Jakub. 2) Today drivers have to drop the reference on BPF progs they hold due to XDP on device teardown themselves. Change this in order to make XDP handling inside the drivers less error prone, and move disabling XDP to the core instead, also from Jakub. 3) Misc set of BPF verifier improvements and cleanups as preparatory work for upcoming BPF-to-BPF calls. Among others, this set also improves liveness marking such that pruning can be slightly more effective. Register and stack liveness information is now included in the verifier log as well, from Alexei. 4) nfp JIT improvements in order to identify load/store sequences in the BPF prog e.g. coming from memcpy lowering and optimizing them through the NPU's command push pull (CPP) instruction, from Jiong. 5) Cleanups to test_cgrp2_attach2.c BPF sample code in oder to remove bpf_prog_attach() magic values and replacing them with actual proper attach flag instead, from David. ==================== Signed-off-by: NDavid S.

Florian Westphal says: ==================== rtnetlink: rework handler (un)registering Peter Zijlstra reported (referring to commit 019a3169, "rtnetlink: add reference counting to prevent module unload while dump is in progress"): 1) it not in fact a refcount, so using refcount_t is silly 2) there is a distinct lack of memory barriers, so we can easily observe the decrement while the msg_handler is still in progress. 3) waiting with a schedule()/yield() loop is complete crap and subject life-locks, imagine doing that rtnl_unregister_all() from a RT task. In ancient times rtnetlink exposed a statically-sized table with preset doit/dumpit handlers to be called for a protocol/type pair. Later the rtnl_register interface was added and the table was allocated on demand. Eventually these were also used by modules. Problem is that nothing prevents module unload while a netlink dump is in progress. netlink dumps can be span multiple recv calls and netlink core saves the to-be-repeated dumper address for later invocation. To prevent rmmod the netlink core expects callers to pass in the owning module so a reference can be taken. So far rtnetlink wasn't doing this, add new interface to pass THIS_MODULE. Moreover, when converting parts of the rtnetlink handling to rcu this code gained way too many READ_ONCE spots, remove them and the extra refcounting. Take a module reference when running dumpit and doit callbacks and never alter content of rtnl_link structures after they have been published via rcu_assign_pointer. Based partially on earlier patch from Peter. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
