9ed13a17e3 Networking fixes for 5.13-rc7, including fixes from wireless, bpf, 
bluetooth, netfilter and can.
 
 Current release - regressions:
 
  - mlxsw: spectrum_qdisc: Pass handle, not band number to find_class()
           to fix modifying offloaded qdiscs
 
  - lantiq: net: fix duplicated skb in rx descriptor ring
 
  - rtnetlink: fix regression in bridge VLAN configuration, empty info
               is not an error, bot-generated "fix" was not needed
 
  - libbpf: s/rx/tx/ typo on umem->rx_ring_setup_done to fix
            umem creation
 
 Current release - new code bugs:
 
  - ethtool: fix NULL pointer dereference during module EEPROM dump via
             the new netlink API
 
  - mlx5e: don't update netdev RQs with PTP-RQ, the special purpose queue
           should not be visible to the stack
 
  - mlx5e: select special PTP queue only for SKBTX_HW_TSTAMP skbs
 
  - mlx5e: verify dev is present in get devlink port ndo, avoid a panic
 
 Previous releases - regressions:
 
  - neighbour: allow NUD_NOARP entries to be force GCed
 
  - further fixes for fallout from reorg of WiFi locking
      (staging: rtl8723bs, mac80211, cfg80211)
 
  - skbuff: fix incorrect msg_zerocopy copy notifications
 
  - mac80211: fix NULL ptr deref for injected rate info
 
  - Revert "net/mlx5: Arm only EQs with EQEs" it may cause missed IRQs
 
 Previous releases - always broken:
 
  - bpf: more speculative execution fixes
 
  - netfilter: nft_fib_ipv6: skip ipv6 packets from any to link-local
 
  - udp: fix race between close() and udp_abort() resulting in a panic
 
  - fix out of bounds when parsing TCP options before packets
    are validated (in netfilter: synproxy, tc: sch_cake and mptcp)
 
  - mptcp: improve operation under memory pressure, add missing wake-ups
 
  - mptcp: fix double-lock/soft lookup in subflow_error_report()
 
  - bridge: fix races (null pointer deref and UAF) in vlan tunnel egress
 
  - ena: fix DMA mapping function issues in XDP
 
  - rds: fix memory leak in rds_recvmsg
 
 Misc:
 
  - vrf: allow larger MTUs
 
  - icmp: don't send out ICMP messages with a source address of 0.0.0.0
 
  - cdc_ncm: switch to eth%d interface naming

14b6cff54e staging: rtl8723bs: avoid bogus gcc warning 
gcc gets confused by some of the type casts and produces an
apparently senseless warning about an out-of-bound memcpy to
an unrelated array in the same structure:

drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c: In function 'rtw_cfg80211_ap_set_encryption':

This is a known gcc bug, and the patch here is only a workaround,
but the approach of using a temporary variable to hold a pointer
to the key also improves readability in addition to avoiding the
warning, so overall this should still help.

12fc11bce6 drm/tegra: Changes for v5.13-rc1 
The changes this time around contain a couple of fixes for host1x along
 with some improvements for Tegra DRM. Most notably the Tegra DRM driver
 now supports the hardware cursor on Tegra186 and later, more correctly
 reflects the capabilities of the display pipelines on various Tegra SoC
 generations and knows how to deal with the dGPU sector layout by using
 framebuffer modifiers.

Linus Torvalds
9d31d23389 Networking changes for 5.13. 
Core:
 
  - bpf:
 	- allow bpf programs calling kernel functions (initially to
 	  reuse TCP congestion control implementations)
 	- enable task local storage for tracing programs - remove the
 	  need to store per-task state in hash maps, and allow tracing
 	  programs access to task local storage previously added for
 	  BPF_LSM
 	- add bpf_for_each_map_elem() helper, allowing programs to
 	  walk all map elements in a more robust and easier to verify
 	  fashion
 	- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
 	  redirection
 	- lpm: add support for batched ops in LPM trie
 	- add BTF_KIND_FLOAT support - mostly to allow use of BTF
 	  on s390 which has floats in its headers files
 	- improve BPF syscall documentation and extend the use of kdoc
 	  parsing scripts we already employ for bpf-helpers
 	- libbpf, bpftool: support static linking of BPF ELF files
 	- improve support for encapsulation of L2 packets
 
  - xdp: restructure redirect actions to avoid a runtime lookup,
 	improving performance by 4-8% in microbenchmarks
 
  - xsk: build skb by page (aka generic zerocopy xmit) - improve
 	performance of software AF_XDP path by 33% for devices
 	which don't need headers in the linear skb part (e.g. virtio)
 
  - nexthop: resilient next-hop groups - improve path stability
 	on next-hops group changes (incl. offload for mlxsw)
 
  - ipv6: segment routing: add support for IPv4 decapsulation
 
  - icmp: add support for RFC 8335 extended PROBE messages
 
  - inet: use bigger hash table for IP ID generation
 
  - tcp: deal better with delayed TX completions - make sure we don't
 	give up on fast TCP retransmissions only because driver is
 	slow in reporting that it completed transmitting the original
 
  - tcp: reorder tcp_congestion_ops for better cache locality
 
  - mptcp:
 	- add sockopt support for common TCP options
 	- add support for common TCP msg flags
 	- include multiple address ids in RM_ADDR
 	- add reset option support for resetting one subflow
 
  - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
 	co-existence with UDP tunnel GRO, allowing the first to take
 	place correctly	even for encapsulated UDP traffic
 
  - micro-optimize dev_gro_receive() and flow dissection, avoid
 	retpoline overhead on VLAN and TEB GRO
 
  - use less memory for sysctls, add a new sysctl type, to allow using
 	u8 instead of "int" and "long" and shrink networking sysctls
 
  - veth: allow GRO without XDP - this allows aggregating UDP
 	packets before handing them off to routing, bridge, OvS, etc.
 
  - allow specifing ifindex when device is moved to another namespace
 
  - netfilter:
 	- nft_socket: add support for cgroupsv2
 	- nftables: add catch-all set element - special element used
 	  to define a default action in case normal lookup missed
 	- use net_generic infra in many modules to avoid allocating
 	  per-ns memory unnecessarily
 
  - xps: improve the xps handling to avoid potential out-of-bound
 	accesses and use-after-free when XPS change race with other
 	re-configuration under traffic
 
  - add a config knob to turn off per-cpu netdev refcnt to catch
 	underflows in testing
 
 Device APIs:
 
  - add WWAN subsystem to organize the WWAN interfaces better and
    hopefully start driving towards more unified and vendor-
    -independent APIs
 
  - ethtool:
 	- add interface for reading IEEE MIB stats (incl. mlx5 and
 	  bnxt support)
 	- allow network drivers to dump arbitrary SFP EEPROM data,
 	  current offset+length API was a poor fit for modern SFP
 	  which define EEPROM in terms of pages (incl. mlx5 support)
 
  - act_police, flow_offload: add support for packet-per-second
 	policing (incl. offload for nfp)
 
  - psample: add additional metadata attributes like transit delay
 	for packets sampled from switch HW (and corresponding egress
 	and policy-based sampling in the mlxsw driver)
 
  - dsa: improve support for sandwiched LAGs with bridge and DSA
 
  - netfilter:
 	- flowtable: use direct xmit in topologies with IP
 	  forwarding, bridging, vlans etc.
 	- nftables: counter hardware offload support
 
  - Bluetooth:
 	- improvements for firmware download w/ Intel devices
 	- add support for reading AOSP vendor capabilities
 	- add support for virtio transport driver
 
  - mac80211:
 	- allow concurrent monitor iface and ethernet rx decap
 	- set priority and queue mapping for injected frames
 
  - phy: add support for Clause-45 PHY Loopback
 
  - pci/iov: add sysfs MSI-X vector assignment interface
 	to distribute MSI-X resources to VFs (incl. mlx5 support)
 
 New hardware/drivers:
 
  - dsa: mv88e6xxx: add support for Marvell mv88e6393x -
 	11-port Ethernet switch with 8x 1-Gigabit Ethernet

 	- page_to_skb() use build_skb when there's sufficient tailroom
 	  (21% improvement for 1000B UDP frames)
 	- support XDP even without dedicated Tx queues - share the Tx
 	  queues with the stack when necessary
 
  - mlx5:
 	- flow rules: add support for mirroring with conntrack,
 	  matching on ICMP, GTP, flex filters and more
 	- support packet sampling with flow offloads
 	- persist uplink representor netdev across eswitch mode
 	  changes
 	- allow coexistence of CQE compression and HW time-stamping
 	- add ethtool extended link error state reporting
 
  - ice, iavf: support flow filters, UDP Segmentation Offload

35655ceb31 Here's a collection of largely clk driver updates for the merge window. The 
usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
 Rockchip, but it feels pretty light on commits. There's only one real commit to
 the framework core and that's to consolidate code. Otherwise the diffstat is
 dominated by many Qualcomm clk driver patches that modernize the driver for the
 proper way of speciying clk parents. That's shifting data around, which could
 subtly break things so I'll be on the lookout for fixes.
 
 New Drivers:
  - Proper clk driver for Mediatek MT7621 SoCs
  - Support for the clock controller on the new Rockchip rk3568
 
 Updates:
  - Simplify Zynq Kconfig dependencies
  - Use clk_hw pointers in socfpga driver
  - Cleanup parent data in qcom clk drivers
  - Some cleanups for rk3399 modularization
  - Fix reparenting of i.MX UART clocks by initializing only the ones
    associated to stdout
  - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
  - Make i.MX LPCG and SCU clocks return on registering failure
  - Kernel doc fixes
  - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
  - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
  - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U
  - Sigma-delta modulation on Allwinner V3s audio PLL

4a0225c3d2 spi: Updates for v5.13 
The only core work for SPI this time around is the completion of the
 conversion to the new style method for specifying transfer delays,
 meaning we can cope with what most controllers support more directly
 using conversions in the core rather than open coding in drivers.
 Otherwise it's a good stack of cleanups and fixes plus a few new
 drivers.
 
 The conversion to new style transfer delay will cause an issue with a
 newly added staging driver which has a straightforward resolution in
 -next.
 
  - Completion of the conversion to new style transfer delay
    configuration.
  - Introduction and use of module_parport_driver() helper, merged here
    as there's no parport tree.
  - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
    MediaTek MT8195,

d08410d8c9 TTY/Serial driver updates for 5.13-rc1 
Here is the big set of tty and serial driver updates for 5.13-rc1.
 
 Actually busy this release, with a number of cleanups happening:
 	- much needed core tty cleanups by Jiri Slaby
 	- removal of unused and orphaned old-style serial drivers.  If
 	  anyone shows up with this hardware, it is trivial to restore
 	  these but we really do not think they are in use anymore.
 	- fixes and cleanups from Johan Hovold on a number of termios
 	  setting corner cases that loads of drivers got wrong as well
 	  as removing unneeded code due to tty core changes from long
 	  ago that were never propagated out to the drivers
 	- loads of platform-specific serial port driver updates and
 	  fixes
 	- coding style cleanups and other small fixes and updates all
 	  over the tty/serial tree.
 
 All of these have been in linux-next for a while now with no reported
 issues.

   - removal of unused and orphaned old-style serial drivers. If anyone
     shows up with this hardware, it is trivial to restore these but we
     really do not think they are in use anymore.

   - fixes and cleanups from Johan Hovold on a number of termios setting
     corner cases that loads of drivers got wrong as well as removing
     unneeded code due to tty core changes from long ago that were never
     propagated out to the drivers

   - loads of platform-specific serial port driver updates and fixes

   - coding style cleanups and other small fixes and updates all over
     the tty/serial tree.

  All of these have been in linux-next for a while now with no reported
  issues"

79df841b43 staging: rtl8723bs: replace DBG_871X_LEVEL logs with netdev_*() 
Replace DBG_871X_LEVEL logs with netdev_*() functions
where possible (i.e. where a pointer to netdev is easily

This is not possible in correspondance of redundant
log in module initialization.

So remove those ones.

DBG_871X_LEVEL macro wraps a raw printk call which is not
recommended in a device driver context, prefer using
netdev_*() log functions.

The remove/replace operation has been done with the

Some of the H265 status flags are wrong. Redefine them to corespond to
Allwinner CedarC open source userspace library. Only one of these flags
is actually used and new value also matches value used in libvdpau-sunxi
library, which is proven to be working.

Note that wrong (old) value in right circumstances (in combination with
another H265 decoding bug) causes driver lock up. With this fix decoding
is still broken (green output) but at least driver doesn't lock up.

8ffdff6a8c staging: comedi: move out of staging directory 
The comedi code came into the kernel back in 2008, but traces its
lifetime to much much earlier.  It's been polished and buffed and
there's really nothing preventing it from being part of the "real"
portion of the kernel.

So move it to drivers/comedi/ as it belongs there.

Many thanks to the hundreds of developers who did the work to make this
happen.

The sdio_drv_priv structure is a small wrapper around sdio_driver in

drv_registered is never used anywhere in the driver and only assigned to

remove sdio_drv_priv and use the sdio_driver structure directly.

69c3331aa0 staging: rtl8723bs: replace dump_drv_version() usage with netdev_dbg() 
replace dump_drv_version() usage with netdev_dbg().

There's no need to further wrap a netdev_dbg() call
for such a low number of occurrences.

The string printed is the same contained in DBG_871X_SEL_NL macro
called inside dump_drv_version().

This is just preparation before bulk DBG_871X_SEL_NL macro
replacement by coccinelle, as the semantic patch that will be
used just replaces, doesn't remove.

3d7ac04029 staging: rtl8723bs: core: Remove unused but set variable 
Removed "ledBlink_param" because it was set to the value of "pbuf" but was
never reused. This set was made by direct assignment (no helper had been
called), therefore it had no side effect to the location pointed by "pbuf".

Moved "static const struct channel_table[]" from include/rtw_mlme_ext.h

83216e3988 of: net: pass the dst buffer to of_get_mac_address() 
of_get_mac_address() returns a "const void*" pointer to a MAC address.
Lately, support to fetch the MAC address by an NVMEM provider was added.
But this will only work with platform devices. It will not work with
PCI devices (e.g. of an integrated root complex) and esp. not with DSA
ports.

There is an of_* variant of the nvmem binding which works without
devices. The returned data of a nvmem_cell_read() has to be freed after
use. On the other hand the return of_get_mac_address() points to some
static data without a lifetime. The trick for now, was to allocate a
device resource managed buffer which is then returned. This will only
work if we have an actual device.

Change it, so that the caller of of_get_mac_address() has to supply a
buffer where the MAC address is written to. Unfortunately, this will
touch all drivers which use the of_get_mac_address().

Usually the code looks like:

  const char *addr;
  addr = of_get_mac_address(np);
  if (!IS_ERR(addr))
    ether_addr_copy(ndev->dev_addr, addr);

This can then be simply rewritten as:

  of_get_mac_address(np, ndev->dev_addr);

Sometimes is_valid_ether_addr() is used to test the MAC address.
of_get_mac_address() already makes sure, it just returns a valid MAC
address. Thus we can just test its return code. But we have to be
careful if there are still other sources for the MAC address before the
of_get_mac_address(). In this case we have to keep the
is_valid_ether_addr() call.

The following coccinelle patch was used to convert common cases to the
new style. Afterwards, I've manually gone over the drivers and fixed the
return code variable: either used a new one or if one was already
available use that. Mansour Moufid, thanks for that coccinelle patch!

07ff20cf17 staging: fieldbus: simplify devm_anybuss_host_common_probe 
Use devm_add_action_or_reset() instead of devres_alloc() and
devres_add(), which works the same. This will simplify the
code. There is no functional changes.
