Pull networking fixes from Jakub Kicinski:
 "Networking fixes, including fixes from bpf, wireless, netfilter and
  wireguard trees.

  The bpf vs lockdown+audit fix is the most notable.

  Things haven't slowed down just yet, both in terms of regressions in
  current release and largish fixes for older code, but we usually see a
  slowdown only after -rc5.

  Current release - regressions:

   - virtio-net: fix page faults and crashes when XDP is enabled

   - mlx5e: fix HW timestamping with CQE compression, and make sure they
     are only allowed to coexist with capable devices

   - stmmac:
      - fix kernel panic due to NULL pointer dereference of
        mdio_bus_data
      - fix double clk unprepare when no PHY device is connected

  Current release - new code bugs:

   - mt76: a few fixes for the recent MT7921 devices and runtime power
     management

  Previous releases - regressions:

   - ice:
      - track AF_XDP ZC enabled queues in bitmap to fix copy mode Tx
      - fix allowing VF to request more/less queues via virtchnl
      - correct supported and advertised autoneg by using PHY
        capabilities
      - allow all LLDP packets from PF to Tx

   - kbuild: quote OBJCOPY var to avoid a pahole call break the build

  Previous releases - always broken:

   - bpf, lockdown, audit: fix buggy SELinux lockdown permission checks

   - mt76: address the recent FragAttack vulnerabilities not covered by
     generic fixes

   - ipv6: fix KASAN: slab-out-of-bounds Read in
     fib6_nh_flush_exceptions

   - Bluetooth:
      - fix the erroneous flush_work() order, to avoid double free
      - use correct lock to prevent UAF of hdev object

   - nfc: fix NULL ptr dereference in llcp_sock_getname() after failed
     connect

   - ieee802154: multiple fixes to error checking and return values

   - igb: fix XDP with PTP enabled

   - intel: add correct exception tracing for XDP

   - tls: fix use-after-free when TLS offload device goes down and back
     up

   - ipvs: ignore IP_VS_SVC_F_HASHED flag when adding service

   - netfilter: nft_ct: skip expectations for confirmed conntrack

   - mptcp: fix falling back to TCP in presence of out of order packets
     early in connection lifetime

   - wireguard: switch from O(n) to a O(1) algorithm for maintaining
     peers, fixing stalls and a large memory leak in the process

  Misc:

   - devlink: correct VIRTUAL port to not have phys_port attributes

   - Bluetooth: fix VIRTIO_ID_BT assigned number

   - net: return the correct errno code ENOBUF -> ENOMEM

   - wireguard:
      - peer: allocate in kmem_cache saving 25% on peer memory
      - do not use -O3"

Bluetooth: btusb: Fix failing to init controllers with operation firmware

2021-06-03T21:02:17+00:00

Some firmware when operation don't may have broken versions leading to
error like the following:

[    6.176482] Bluetooth: hci0: Firmware revision 0.0 build 121 week 7 2021
[    6.177906] bluetooth hci0: Direct firmware load for intel/ibt-20-0-0.sfi failed with error -2
[    6.177910] Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-20-0-0.sfi (-2)

Since we load the firmware file just to check if its version had changed
comparing to the one already loaded we can just skip since the firmware
is already operation.

Bluetooth: btusb: Revert Fix the autosuspend enable and disable

2021-04-09T16:08:02+00:00

drivers/usb/core/hub.c: usb_new_device() contains the following:

        /* By default, forbid autosuspend for all devices.  It will be
         * allowed for hubs during binding.
         */
        usb_disable_autosuspend(udev);

So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.

This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.

This reverts commit 7bd9fb058d77213130e4b3e594115c028b708e7e.
