When checking whether auto-negotiation is on, driver only needs to check the value of mac.autoneg(SW) directly, and does not need to query it from hardware. Because this value is always synchronized with the auto-negotiation state of hardware. This patch removes mac auto-negotiation state query in hclge_update_speed_duplex().

Driver gets phy address from NCL_config file and uses the phy address to initialize phydev. There are 5 bits for phy address. And C22 phy address has 5 bits. So 0-31 are all valid address for phy. If there is no phy, it will crash. Because driver always get a valid phy address. This patch fixes the phy address to 8 bits, and use 0xff to indicate invalid phy address.

Add a per-device sysctl to specify the default traffic class to use for kernel originated IPv6 Neighbour Discovery packets. Currently this includes: - Router Solicitation (ICMPv6 type 133) ndisc_send_rs() -> ndisc_send_skb() -> ip6_nd_hdr() - Neighbour Solicitation (ICMPv6 type 135) ndisc_send_ns() -> ndisc_send_skb() -> ip6_nd_hdr() - Neighbour Advertisement (ICMPv6 type 136) ndisc_send_na() -> ndisc_send_skb() -> ip6_nd_hdr() - Redirect (ICMPv6 type 137) ndisc_send_redirect() -> ndisc_send_skb() -> ip6_nd_hdr() and if the kernel ever gets around to generating RA's, it would presumably also include: - Router Advertisement (ICMPv6 type 134) (radvd daemon could pick up on the kernel setting and use it) Interface drivers may examine the Traffic Class value and translate the DiffServ Code Point into a link-layer appropriate traffic prioritization scheme. An example of mapping IETF DSCP values to IEEE 802.11 User Priority values can be found here: https://tools.ietf.org/html/draft-ietf-tsvwg-ieee-802-11 The expected primary use case is to properly prioritize ND over wifi.

Patch1 adds a funtionality to open a path in bpf-fs regardless of its object type. Patch2 adds actual functionality by scanning the bpf-fs once and adding object information in hash table, with object id as a key. One object may be associated with multiple paths because an object can be pinned multiple times Patch3 adds command line option to enable this functionality.

Josef Bacik says: ==================== Add the ability to do BPF directed error injection I'm sending this through Dave since it'll conflict with other BPF changes in his tree, but since it touches tracing as well Dave would like a review from somebody on the tracing side. v4->v5: - disallow kprobe_override programs from being put in the prog map array so we don't tail call into something we didn't check. This allows us to make the normal path still fast without a bunch of percpu operations. v3->v4: - fix a build error found by kbuild test bot (I didn't wait long enough apparently.) - Added a warning message as per Daniels suggestion. v2->v3: - added a ->kprobe_override flag to bpf_prog. - added some sanity checks to disallow attaching bpf progs that have ->kprobe_override set that aren't for ftrace kprobes. - added the trace_kprobe_ftrace helper to check if the trace_event_call is a ftrace kprobe. - renamed bpf_kprobe_state to bpf_kprobe_override, fixed it so we only read this value in the kprobe path, and thus only write to it if we're overriding or clearing the override. v1->v2: - moved things around to make sure that bpf_override_return could really only be used for an ftrace kprobe. - killed the special return values from trace_call_bpf. - renamed pc_modified to bpf_kprobe_state so bpf_override_return could tell if it was being called from an ftrace kprobe context. - reworked the logic in kprobe_perf_func to take advantage of bpf_kprobe_state. - updated the test as per Alexei's review. - Original message - A lot of our error paths are not well tested because we have no good way of injecting errors generically. Some subystems (block, memory) have ways to inject errors, but they are random so it's hard to get reproduceable results. With BPF we can add determinism to our error injection. We can use kprobes and other things to verify we are injecting errors at the exact case we are trying to test. This patch gives us the tool to actual do the error injection part. It is very simple, we just set the return value of the pt_regs we're given to whatever we provide, and then override the PC with a dummy function that simply returns. Right now this only works on x86, but it would be simple enough to expand to other architectures. Thanks, ==================== Signed-off-by:

Error injection is sloppy and very ad-hoc. BPF could fill this niche perfectly with it's kprobe functionality. We could make sure errors are only triggered in specific call chains that we care about with very specific situations. Accomplish this with the bpf_override_funciton helper. This will modify the probe'd callers return value to the specified value and set the PC to an override function that simply returns, bypassing the originally probed function. This gives us a nice clean way to implement systematic error injection for all of our code paths. Acked-by:

Manish Kurup says: ==================== net_sched actions: act_vlan now uses RCU This commit consists of 3 patches: patch1 (1/3): The VLAN action maintains one set of stats across all cores, and uses a spinlock to synchronize updates to it from the same. Changed this to use a per-CPU stats context instead. This change will result in better performance. patch2 (2/3): Modified netronome nfp flower action to use VLAN helper functions instead of accessing/referencing TC act_vlan private structures directly. patch3 (3/3): Using a spinlock in the VLAN action causes performance issues when the VLAN action is used on multiple cores. Rewrote the VLAN action to use RCU read locking for reads and updates instead. All functions now use an RCU dereferenced pointer to access the VLAN action context. Modified helper functions used by other modules, to use the RCU as opposed to directly accessing the structure. As part of this review, there were some changes suggested by reviewers. I have incorporated all the changes that were requested. Here're the changes: v2: Fixed all helper functions to use RCU (rtnl_dereference) - Eric, Jamal v2: Fixed indentation, extra line nits - Jamal, Jiri v2: Moved rcu_head to the end of the struct - Jiri v2: Re-formatted locals to reverse-christmas-tree - Jiri v2: Removed mismatched spin_lock() - Cong v2: Removed spin_lock_bh() in tcf_vlan_init, rtnl_dereference() should suffice - Cong, Jiri v4: Modified the nfp flower action code to use the VLAN helper functions instead of referencing the structure directly. Isolated this into a separate patch - Pieter Jansen v5: Got rid of the unlikely() for the allocation case - Simon Horman v6: Had forgotten cleanup functions for RCU alloc, added them - Dave Miller v7: Re-formatted more locals to reverse-christmas-tree - Pieter V v8: Reverted reverse-christmas-tree(v7), not required when dependencies make it difficult to implement - Alexander D v9: Cover letter subject change - Jamal ==================== Signed-off-by:

But when changing link, ip_tunnel_changelink doesn't even update i/o_flags, and also the update of these flags would cause some other gre's properties need to be updated or recalculated.

Now ip_gre is using ip_tunnel_changelink to update it's properties, but ip_tunnel_changelink in ip_tunnel doesn't update i/o_flags as a common function. o_flags updates would cause that tunnel->tun_hlen / hlen and dev->mtu / needed_headroom need to be recalculated, and dev->(hw_)features need to be updated as well. Therefore, we can't just add the update into ip_tunnel_update called in ip_tunnel_changelink, and it's also better not to touch ip_tunnel codes. This patch updates i/o_flags and calls ipgre_link_update to recalculate these gre properties after ip_tunnel_changelink does the common update. Note that since ipgre_link_update doesn't know the lower dev, it will update gre->hlen, dev->mtu and dev->needed_headroom with the value of 'new tun_hlen - old tun_hlen'. In this way, we can avoid many redundant codes, unlike ip6_gre. Reported-by:

The software bridge can be build with vlan filtering support included. However, by default it is turned off. In its turned off state, it still passes VLANs via switchev, even though they are not to be used. Don't pass these VLANs to the hardware. Only do so when vlan filtering is enabled. This fixes at least one corner case. There are still issues in other corners, such as when vlan_filtering is later enabled. Signed-off-by:

Andrew Lunn says: ==================== IGMP snooping for local traffic The linux bridge supports IGMP snooping. It will listen to IGMP reports on bridge ports and keep track of which groups have been joined on an interface. It will then forward multicast based on this group membership. When the bridge adds or removed groups from an interface, it uses switchdev to request the hardware add an mdb to a port, so the hardware can perform the selective forwarding between ports. What is not covered by the current bridge code, is IGMP joins/leaves from the host on the brX interface. These are not reported via switchdev so that hardware knows the local host is interested in the multicast frames. Luckily, the bridge does track joins/leaves on the brX interface. The code is obfusticated, which is why i missed it with my first attempt. So the first patch tries to remove this obfustication. Currently, there is no notifications sent when the bridge interface joins a group. The second patch adds them. bridge monitor then shows joins/leaves in the same way as for other ports of the bridge. Then starts the work passing down to the hardware that the host has joined/left a group. The existing switchdev mdb object cannot be used, since the semantics are different. The existing SWITCHDEV_OBJ_ID_PORT_MDB is used to indicate a specific multicast group should be forwarded out that port of the switch. However here we require the exact opposite. We want multicast frames for the group received on the port to the forwarded to the host. Hence add a new object SWITCHDEV_OBJ_ID_HOST_MDB, a multicast database entry to forward to the host. This new object is then propagated through the DSA layers. No DSA driver changes should be needed, this should just work... This version fixes up the nitpick from Nikolay, removes an unrelated white space change, and adds in a patch adding a few const attributes to a couple of functions taking a port parameter, in order to stop the following patch produces warnings. ==================== Acked-by:

Pull sound fixes from Takashi Iwai: "The amount of the changes isn't as quite small as wished, nevertheless they are straight fixes that deserve merging to 4.14 final. Most of fixes are about ALSA core bugs spotted by fuzzer: a follow-up fix for the previous nested rwsem patch, a fix to avoid the resource hogs due to too many concurrent ALSA timer invocations, and a fix for a crash with SYSEX MIDI transfer over OSS sequencer emulation that is used by none but fuzzer. The rest are usual HD-audio and USB-audio device-specific quirks, which are safe to apply" * tag 'sound-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda - fix headset mic problem for Dell machines with alc274 ALSA: seq: Fix OSS sysex delivery in OSS emulation ALSA: seq: Avoid invalid lockdep class warning ALSA: timer: Limit max instances per timer ALSA: usb-audio: support new Amanero Combo384 firmware version
