Martin KaFai Lau 9c4713701c bpf: Fix bpf_xdp_event_output
Fix a typo. xdp->data instead of xdp should be copied to the perf-event's
dst_buff.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Revisit warning logic when not applying default helper assignment.
   Jiri Kosina considers we are breaking existing setups and not warning
   our users accordinly now that automatic helper assignment has been
   turned off by default. So let's make him happy by spotting the warning
   by when we find a helper but we cannot attach, instead of warning on the
   former deprecated behaviour. Patch from Jiri Kosina.

2) Two patches to fix regression in ctnetlink interfaces with
   nfnetlink_queue. Specifically, perform more relaxed in CTA_STATUS
   and do not bail out if CTA_HELP indicates the same helper that we
   already have. Patches from Kevin Cernekee.

3) A couple of bugfixes for ipset via Jozsef Kadlecsik. Due to wrong
   index logic in hash set types and null pointer exception in the
   list:set type.

4) hashlimit bails out with correct userspace parameters due to wrong
   arithmetics in the code that avoids "divide by zero" when
   transforming the userspace timing in milliseconds to token credits.
   Patch from Alban Browaeys.

5) Fix incorrect NFQA_VLAN_MAX definition, patch from
   Ken-ichirou MATSUZAWA.

6) Don't not declare nfnetlink batch error list as static, since this
   may be used by several subsystems at the same time. Patch from
   Liping Zhang.

Jack Morgenstein 6ed63d845e net/mlx4_core: Use cq quota in SRIOV when creating completion EQs
When creating EQs to handle CQ completion events for the PF
or for VFs, we create enough EQE entries to handle completions
for the max number of CQs that can use that EQ.

When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource tracker).
Therefore, when creating an EQ, the number of EQE entries that the VF
should request for that EQ is the CQ quota value (and not the total
number of CQs available in the FW).

Under SRIOV, the PF, also must use its CQ quota, because
the resource tracker also controls how many CQs the PF can obtain.

Using the FW total CQs instead of the CQ quota when creating EQs resulted
wasting MTT entries, due to allocating more EQEs than were needed.

Majd Dibbiny 95f1ba9a24 net/mlx4_core: Fix VF overwrite of module param which disables DMFS on new probed PFs
In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.

log_num_mgm_entry_size is a global module parameter which
affects all ConnectX-3 PFs installed on that host.
If a VF changes log_num_mgm_entry_size, this will affect all PFs
which are probed subsequent to the change (by disabling DMFS for
those PFs).

Mellanox mlx5e fixes for 4.11-rc1

This series includes some important bug fixes for mlx5e driver.

Three misc fixes:
From Mohamad, compilation fix on s390 system
From Me, A fix for driver unload when switchdev mode is on.
From Tariq, HW LRO frag size optimization for when build_skb is not used
(striding RQ mode).

Three CQE compression related fixes:
Two fixes from Tariq and I, to correctly setup CQE compression
parameters on driver load and on arbitrary user modifications.
Last patch, fixes a very critical issue that was originally reported
by Tom, where the driver reported csum errors or even page ref issues
for when cqe compression is enabled and rapidly active.

For your convenience this series was generated on top of net-next branch:

Tariq Toukan 36154be40a net/mlx5e: Fix wrong CQE decompression
In cqe compression with striding RQ, the decompression of the CQE field
wqe_counter was done with a wrong wraparound value.
This caused handling cqes with a wrong pointer to wqe (rx descriptor)
and creating SKBs with wrong data, pointing to wrong (and already consumed)
strides/pages.

The meaning of the CQE field wqe_counter in striding RQ holds the
stride index instead of the WQE index. Hence, when decompressing
a CQE, wqe_counter should have wrapped-around the number of strides
in a single multi-packet WQE.

We dropped this wrap-around mask at all in CQE decompression of striding
RQ. It is not needed as in such cases the CQE compression session would
break because of different value of wqe_id field, starting a new
compression session.

Tested:
 ethtool -K ethxx lro off/on
 ethtool --set-priv-flags ethxx rx_cqe_compress on
 super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D
 verified no csum errors and no page refcount issues.

Saeed Mahameed 6dc4b54e77 net/mlx5e: Update MPWQE stride size when modifying CQE compress state
When the admin enables/disables cqe compression, updating
mpwqe stride size is required:
    CQE compress ON  ==> stride size = 256B
    CQE compress OFF ==> stride size = 64B

This is already done on driver load via mlx5e_set_rq_type_params, all we
need is just to call it on arbitrary admin changes of cqe compression
state via priv flags or when changing timestamping state
(as it is mutually exclusive with cqe compression).

This bug introduces no functional damage, it only makes cqe compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.

Tested:
 ethtool --set-priv-flags ethxx rx_cqe_compress on
 pktgen with  64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
 verify `ethtool -S ethxx | grep compress` are advancing more often
 (rapidly)

Tariq Toukan b0d4660b4c net/mlx5e: Fix broken CQE compression initialization
Some of RQ type parameters are derived from CQE compression state flag,
CQE compression flag was initialized only after RQ type parameters
setup. This leads to load RQ with stride size smaller than what we
want for when CQE compression is on.

This bug introduces no functional damage, it only makes CQE compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.

Fix this by marking default status of CQE compression in PFLAG prior to
calling mlx5e_set_rq_priv_params(), as it inits some fields based on it.

Tested:
 load driver on systems where rx CQE compress will be on (MH)
 pktgen with  64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
 verify `ethtool -S ethxx | grep compress` are advancing more often

Currently vport representors are added only on driver load and removed on

seamless reset flow feature.  This caused to leave the representors

error reset flows.

To overcome this we move their handling to interface attach/detach, so
they would be cleaned up on shutdown and recreated on reset flows.

As no uapi header provides a definition of struct sockaddr, inclusion
of <sys/socket.h> seems to be the most conservative and the only safe
fix available.

All current users of <linux/if.h> are very likely to be including
<sys/socket.h> already because the latter is the sole provider
of struct sockaddr definition in libc, so adding a uapi header
with a definition of struct sockaddr would create a potential
conflict with <sys/socket.h>.

Replacing struct sockaddr in the definition of struct ifreq with
a different type would create a potential incompatibility with current
users of struct ifreq who might rely on ifru_addr et al members being
of type struct sockaddr.

Ridge Kennedy 12d656af4e l2tp: Avoid schedule while atomic in exit_net
While destroying a network namespace that contains a L2TP tunnel a
"BUG: scheduling while atomic" can be observed.

Enabling lockdep shows that this is happening because l2tp_exit_net()
is calling l2tp_tunnel_closeall() (via l2tp_tunnel_delete()) from
within an RCU critical section.

l2tp_exit_net() takes rcu_read_lock_bh()
  << list_for_each_entry_rcu() >>
  l2tp_tunnel_delete()
    l2tp_tunnel_closeall()
      __l2tp_session_unhash()
        synchronize_rcu() << Illegal inside RCU critical section >>

BUG: sleeping function called from invalid context

 $ dmesg
 ...
 [942121.089216] BUG: scheduling while atomic: kworker/u16:3/13872/0x00000200
 ...

To fix this, move the call to l2tp_tunnel_closeall() out of the RCU
critical section, and instead call it from l2tp_tunnel_del_work(), which
is running from the l2tp_wq workqueue.

Christian Lamparter a577ca6bad net: emac: add support for device-tree based PHY discovery and setup
This patch adds glue-code that allows the EMAC driver to interface
with the existing dt-supported PHYs in drivers/net/phy.

Because currently, the emac driver maintains a small library of
supported phys for in a private phy.c file located in the drivers
directory.

The support is limited to mostly single ethernet transceiver like the:
CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035.

However, routers like the Netgear WNDR4700 and Cisco Meraki MX60(W)
have a 5-port switch (AR8327N) attached to the EMAC. The switch chip
is supported by the qca8k mdio driver, which uses the generic phy
library. Another reason is that PHYLIB also supports the BCM54610,
which was used for the Western Digital My Book Live.

This will now also make EMAC select PHYLIB.

  - The ability for a guest to ask the hypervisor to resize the guest's hash
    table, and in addition support for doing so automatically when memory is
    hotplugged into/out-of the guest. This allows the hash table to be sized
    based on the current memory usage of the guest, rather than the maximum
    possible memory usage.
 
  - Implementation of optprobes (kprobe optimisation) for powerpc.
 
 In addition there's the topic branch shared with the KVM tree, which includes
 support for guests to use the Radix MMU on Power9.

Linus Torvalds 5ab356626f Pin control bulk changes for the v4.11 kernel cycle:
Core changes:
 
 - Switch the generic pin config argument from 16 to 24 bits,
   only use 8 bits for the configuration type. We might need to
   encode more information about a certain setting than we need
   to encode different generic settings.
 
 - Add a cross-talk API to the pin control GPIO back-end,
   utilizing pinctrl_gpio_set_config() from GPIO drivers that
   want to set up a certain pin configuration in the back-end.
   This also includes the .set_config() refactoring of the
   GPIO chips, so that they pass a generic configuration for
   things like debouncing and single ended (typically open
   drain). This change has also been merged in an immutable
   branch to the GPIO tree.
 
 - Take hogs with a delayed work, so that we finalize probing
   a pin controller before trying to get any hogs.
 
 - For pin controllers putting all group and function definitions
   into the device tree, we now have generic code to deal with
   this and it is used in two drivers so far.
 
 - Simplifications of the pin request conflict check.
 
 - Make dt_free_map() optional.
 
 Updates to drivers:
 
 - pinctrl-single now use the generic helpers to generate dynamic
   group and function tables from the device tree.
 
 - Texas Instruments IOdelay configuration driver add-on to
   pinctrl-single.
 
 - i.MX: use radix trees to store groups and functions, use the new
   generic group and function helpers to manage them.
 
 - Intel: add support for hardware debouncing and 1K pull-down.
   New subdriver for the Gemini Lake SoC.
 
 - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
   MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
 
 - Aspeed: use syscon cross-dependencies to set up related bits in
   the LPC host controller and display controller.
 
 - Aspeed: finalize G4 and G5 support. Fix mux configuration on
   GPIOs. Add banks Y, Z, AA, AB and AC.
 
 - AMD: support additional GPIO.
 
 - STM32: set this controller to strict muxing mode.
   STM32H743 MCU support.
 
 - Allwinner sunxi: deep simplifications on how to support
   subvariants of SoCs without adding to much SoC-specific data
   for each subvariant, especially for sun5i variants. New driver
   for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
   variants with the new variant framework.
 
 - Mvebu: simplifications to use a MMIO and regmap abstraction.
   New subdrivers for the 98DX3236, 98DX5241 SoCs.
 
 - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
   SoC driver to access regmaps. Add infrastructure for pin-bank
   retention control. Clean out the pin retention control from
   arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
   in the Samsung pin control driver(s).
 
 - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
 
 - Qualcomm: use raw spinlock variants: this makes the qualcomm
   driver realtime-safe.

Merge tag 'pinctrl-v4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "Pin control bulk changes for the v4.11 kernel cycle.

  Core changes:

   - Switch the generic pin config argument from 16 to 24 bits, only use
     8 bits for the configuration type. We might need to encode more
     information about a certain setting than we need to encode
     different generic settings.

   - Add a cross-talk API to the pin control GPIO back-end, utilizing
     pinctrl_gpio_set_config() from GPIO drivers that want to set up a
     certain pin configuration in the back-end.

     This also includes the .set_config() refactoring of the GPIO chips,
     so that they pass a generic configuration for things like
     debouncing and single ended (typically open drain). This change has
     also been merged in an immutable branch to the GPIO tree.

   - Take hogs with a delayed work, so that we finalize probing a pin
     controller before trying to get any hogs.

   - For pin controllers putting all group and function definitions into
     the device tree, we now have generic code to deal with this and it
     is used in two drivers so far.

   - Simplifications of the pin request conflict check.

   - Make dt_free_map() optional.

  Updates to drivers:

   - pinctrl-single now use the generic helpers to generate dynamic
     group and function tables from the device tree.

   - Texas Instruments IOdelay configuration driver add-on to
     pinctrl-single.

   - i.MX: use radix trees to store groups and functions, use the new
     generic group and function helpers to manage them.

   - Intel: add support for hardware debouncing and 1K pull-down. New
     subdriver for the Gemini Lake SoC.

   - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
     MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.

   - Aspeed: use syscon cross-dependencies to set up related bits in the
     LPC host controller and display controller.

   - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
     Add banks Y, Z, AA, AB and AC.

   - AMD: support additional GPIO.

   - STM32: set this controller to strict muxing mode. STM32H743 MCU
     support.

   - Allwinner sunxi: deep simplifications on how to support subvariants
     of SoCs without adding to much SoC-specific data for each
     subvariant, especially for sun5i variants. New driver for V3s SoCs.
     New driver for the H5 SoC. Support A31/A31s variants with the new
     variant framework.

   - Mvebu: simplifications to use a MMIO and regmap abstraction. New
     subdrivers for the 98DX3236, 98DX5241 SoCs.

   - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
     driver to access regmaps. Add infrastructure for pin-bank retention
     control. Clean out the pin retention control from
     arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
     the Samsung pin control driver(s).

   - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.

   - Qualcomm: use raw spinlock variants: this makes the qualcomm driver
     realtime-safe"

Jiri Kosina 2fa299a917 HID: rmi: fallback to generic/multitouch if hid-rmi is not built
Commit 279967a65b ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
unconditionally switches over handling of all Synaptics touchpads to hid-rmi
(to make use of extended features of the HW); in case CONFIG_HID_RMI is
disabled though this renders the touchpad unusable, as the

	HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)

match doesn't exist and generic/multitouch doesn't bind to it either (due
to hid group mismatch).

Fix this by switching over to hid-rmi only if it has been actually built.

Merge tag 'extable-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull exception table module split from Paul Gortmaker:
 "Final extable.h related changes.

  This completes the separation of exception table content from the
  module.h header file. This is achieved with the final commit that
  removes the one line back compatible change that sourced extable.h
  into the module.h file.

  The commits are unchanged since January, with the exception of a
  couple Acks that came in for the last two commits a bit later. The
  changes have been in linux-next for quite some time[1] and have got
  widespread arch coverage via toolchains I have and also from
  additional ones the kbuild bot has.

  Maintaners of the various arch were Cc'd during the postings to
  lkml[2] and informed that the intention was to take the remaining arch
  specific changes and lump them together with the final two non-arch
  specific changes and submit for this merge window.

  The ia64 diffstat stands out and probably warrants a mention. In an
  earlier review, Al Viro made a valid comment that the original header
  separation of content left something to be desired, and that it get
  fixed as a part of this change, hence the larger diffstat"
