      xhci: set missing SuperSpeedPlus Link Protocol bit in roothub descriptor · 7bea22b1
      Mathias Nyman authored
      A SuperSpeedPlus roothub needs to have the Link Protocol (LP) bit set in
      the bmSublinkSpeedAttr[] entry of a SuperSpeedPlus descriptor.
      
      If the xhci controller has an optional Protocol Speed ID (PSI) table then
      that will be used as a base to create the roothub SuperSpeedPlus
      descriptor.
      The PSI table does not however necessary contain the LP bit so we need
      to set it manually.
      
      Check the psi speed and set LP bit if speed is 10Gbps or higher.
      We're not setting it for 5 to 10Gbps as USB 3.1 specification always
      mention SuperSpeedPlus for 10Gbps or higher, and some SSIC USB 3.0 speeds
      can be over 5Gbps, such as SSIC-G3B-L1 at 5830 Mbps

      xhci: Fix sleeping with spin_lock_irq() held in ASmedia 1042A workaround · 4ec1cd3e
      Mathias Nyman authored
      The flow control workaround for ASM1042A xHC hosts sleeps between
      register polling. The workaround gets called in several places, among
      them with spin_lock_irq() held when xHC host is resumed or hoplug removed.
      
      This was noticed as kernel panics at resume on a Dell XPS15 9550 with
      TB16 thunderbolt dock.
      
      Avoid sleeping with spin_lock_irq() held, use udelay() instead
      
      The original workaround was added to 4.9 and 4.12 stable releases,
      this patch needs to be applied to those as well.

      usb: host: xhci-plat: allow sysdev to inherit from ACPI · c6b8e793
      Adam Wallis authored
      Commit 4c39d4b9 ("usb: xhci: use bus->sysdev for DMA configuration")
      updated the method determining DMA for XHCI from sysdev. However, this
      patch broke the ability to enumerate the FWNODE from parent ACPI devices
      from the child plat XHCI device.
      
      Currently, xhci_plat is not set up properly when the parent device is an
      ACPI node. The conditions that xhci_plat_probe should satisfy are
      
      1. xhci_plat comes from firmware
      2. xhci_plat is child of a device from firmware (dwc3-plat)
      3. xhci_plat is grandchild of a pci device (dwc3-pci)
      
      Case 2 is covered when the child is an OF node (by checking
      sysdev->parent->of_node), however, an ACPI parent will return NULL in
      the of_node check and will thus not result in sysdev being set to
      sysdev->parent
      
      [   17.591549] xhci-hcd: probe of xhci-hcd.6.auto failed with error -5
      
      This change adds a check for ACPI to completely allow for condition 2.
      This is done by first checking if the parent node is of type ACPI (e.g.,
      dwc3-plat) and set sysdev to sysdev->parent if either of the two
      following conditions are met:
      
      1: If fwnode is empty (in the case that platform_device_add_properties
      was not called on the allocated platform device)
      2: fwnode exists but is not of type ACPI (this would happen if
      platform_device_add_properties was called on the allocated device.
      Instead of type FWNODE_ACPI, you would end up with FWNODE_PDATA)

      usb: pci-quirks.c: Corrected timeout values used in handshake · 114ec3a6
      Jim Dickerson authored
      Servers were emitting failed handoff messages but were not
      waiting the full 1 second as designated in section 4.22.1 of
      the eXtensible Host Controller Interface specifications. The
      handshake was using wrong units so calls were made with milliseconds
      not microseconds. Comments referenced 5 seconds not 1 second as
      in specs.
      
      The wrong units were also corrected in a second handshake call.

      xhci: fix finding correct bus_state structure for USB 3.1 hosts · 5a838a13
      Mathias Nyman authored
      xhci driver keeps a bus_state structure for each hcd (usb2 and usb3)
      
      The structure is picked based on hcd speed, but driver only compared
      for HCD_USB3 speed, returning the wrong bus_state for HCD_USB31 hosts.
      
      This caused null pointer dereference errors in bus_resume function.

      usb: xhci: Free the right ring in xhci_add_endpoint() · 9821786d
      Lu Baolu authored
      In the xhci_add_endpoint(), a new ring was allocated and saved at
      xhci_virt_ep->new_ring. Hence, when error happens, we need to free
      the allocated ring before returning error.
      
      Current code frees xhci_virt_ep->ring instead of the new_ring. This
      patch fixes this.

      usb: Increase quirk delay for USB devices · b2a542bb
      Dmitry Fleytman authored
      Commit e0429362
      ("usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e")
      introduced quirk to workaround an issue with some Logitech webcams.
      
      The workaround is introducing delay for some USB operations.
      
      According to our testing, delay introduced by original commit
      is not long enough and in rare cases we still see issues described
      by the aforementioned commit.
      
      This patch increases delays introduced by original commit.
      Having this patch applied we do not see those problems anymore.

      uwbd_start() calls kthread_run() and checks that the return value is
      not NULL. But the return value is not NULL in case kthread_run() fails,
      it takes the form of ERR_PTR(-EINTR).
      
      Use IS_ERR() instead.

      pruning the original Makefile to the necessary minimum.  The default for
      EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

      mlxsw: spectrum_router: Only handle IPv4 and IPv6 events · 8e29f979
      Ido Schimmel authored
      The driver doesn't support events from address families other than IPv4
      and IPv6, so ignore them. Otherwise, we risk queueing a work item before
      it's initialized.
      
      This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
      is enabled, as the VRF driver will try to add an l3mdev rule for the
      IPMR family.

      sctp: do not mark sk dumped when inet_sctp_diag_fill returns err · 8c7c19a5
      Xin Long authored
      sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill
      returns err, in which case it shouldn't mark sk dumped by setting
      cb->args[3] as 1 in sctp_sock_dump().
      
      Otherwise, it could cause some asocs to have no parent's sk dumped
      in 'ss --sctp'.
      
      So this patch is to not set cb->args[3] when inet_sctp_diag_fill()
      returns err in sctp_sock_dump().

      sctp: fix an use-after-free issue in sctp_sock_dump · d25adbeb
      Xin Long authored
      Commit 86fdb344 ("sctp: ensure ep is not destroyed before doing the
      dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep
      with holding sock and sock lock.
      
      But Paolo noticed that endpoint could be destroyed in sctp_rcv without
      sock lock protection. It means the use-after-free issue still could be
      triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks
      !ep, although it's pretty hard to reproduce.
      
      I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close
      and sctp_sock_dump long time.
      
      This patch is to add another param cb_done to sctp_for_each_transport
      and dump ep->assocs with holding tsp after jumping out of transport's
      traversal in it to avoid this issue.
      
      It can also improve sctp diag dump to make it run faster, as no need
      to save sk into cb->args[5] and keep calling sctp_for_each_transport
      any more.
      
      This patch is also to use int * instead of int for the pos argument
      in sctp_for_each_transport, which could make postion increment only
      in sctp_for_each_transport and no need to keep changing cb->args[2]
      in sctp_sock_filter and sctp_sock_dump any more.

      The default receive buffer size was reduced by recent change
      to a value which was appropriate for 10G and Windows Server 2016.
      But the value is too small for full performance with 40G on Azure.
      Increase the default back to maximum supported by host.

      tcp: update skb->skb_mstamp more carefully · 8c72c65b
      Eric Dumazet authored
      liujian reported a problem in TCP_USER_TIMEOUT processing with a patch
      in tcp_probe_timer() :
            https://www.spinics.net/lists/netdev/msg454496.html
      
      After investigations, the root cause of the problem is that we update
      skb->skb_mstamp of skbs in write queue, even if the attempt to send a
      clone or copy of it failed. One reason being a routing problem.
      
      This patch prevents this, solving liujian issue.
      
      It also removes a potential RTT miscalculation, since
      __tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with
      TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has
      been changed.
      
      A future ACK would then lead to a very small RTT sample and min_rtt
      would then be lowered to this too small value.
      
      Tested:

      rt_iif is only set to the actual egress device for the output path. The
      recent change to consider the l3slave flag when returning IP_PKTINFO
      works for local traffic (the correct device index is returned), but it
      broke the more typical use case of packets received from a remote host
      always returning the VRF index rather than the original ingress device.
      Update the fixup to consider l3slave and rt_iif actually getting set.

      net: smsc911x: Quieten netif during suspend · 2aa70f86
      Geert Uytterhoeven authored
      If the network interface is kept running during suspend, the net core
      may call net_device_ops.ndo_start_xmit() while the Ethernet device is
      still suspended, which may lead to a system crash.
      
      E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
      driven by a PM controlled clock.  If the Ethernet registers are accessed
      while the clock is not running, the system will crash with an imprecise
      external abort.
      
      As this is a race condition with a small time window, it is not so easy
      to trigger at will.  Using pm_test may increase your chances:
      
          # echo 0 > /sys/module/printk/parameters/console_suspend
          # echo platform > /sys/power/pm_test
          # echo mem > /sys/power/state
      
      To fix this, make sure the network interface is quietened during
      suspend.

      Florian Fainelli authored
      We can enter a deadlock situation because there is no sufficient protection
      when ndo_get_stats64() runs in process context to guard against RX or TX NAPI
      contexts running in softirq, this can lead to the following lockdep splat and
      actual deadlock was experienced as well with an iperf session in the background
      and a while loop doing ifconfig + ethtool.

      When building an allmodconfig kernel with gcc-4.6, we get a rather

      I have no idea what this warning is even trying to say, but it does
      seem like a false positive. Reordering the initialization in to match
      the structure definition gets rid of the warning, and might also avoid
      whatever gcc thinks is wrong here.

       "Many many years ago (at the kernel summit in Boston), we all came to
        the agreement that the firmware/ tree should be dropped from the
        kernel, and everyone use the linux-firmware package instead. For some
        minor reason, David Woodhouse didn't send the pull request at that
        point in time, and everyone forgot about this.
      
        The topic came up in the hallway track at the Plumbers conference this
        week, so here's a single patch that drops the whole firmware tree. The
        last firmware update was back in 2013, and all distros have been using
        linux-firmware instead since at least that year, if not before. The
        only commits to that directory since 2013 was some kbuild fixups for
        various build tool issues.
      
        So lets finally drop this, we don't need to lug them around in the
        kernel source tree anymore, especially as no one wants or uses them.
      
        This has passed build testing with 0-day, I don't think it made it
        into linux-next this week, but I figured it was good to get in before
