Bjørn Mork 889bcbdeee net: ethernet: mediatek: support MT7621 SoC ethernet hardware
The Mediatek MT7621 SoC contains the same ethernet hardware module as
used on a number of other MediaTek SoC parts. There are some minor
differences to deal with but we can use the same driver to support
them all.

This patch is based on work by Bjørn Mork <bjorn@mork.no>, and his
original patch is at:

3293bc63f5

There is an additional compatible devicetree type added, and the primary
change to the code required is to support a single interrupt (for both
RX and TX interrupts).

====================
mlxsw: spectrum_acl: Include delta bits into hashtable key

The Spectrum-2 ASIC allows multiple rules to use the same mask provided
that the difference between their masks is small enough (up to 8
consecutive delta bits). A more detailed explanation is provided in
merge commit 756cd36626 ("Merge branch
'mlxsw-Introduce-algorithmic-TCAM-support'").

These delta bits are part of the rule's key and therefore rules that
only differ in their delta bits can be inserted with the same A-TCAM
mask. In case two rules share the same key and only differ in their
priority, then the second will spill to the C-TCAM.

Current code does not take the delta bits into account when checking for
duplicate rules, which leads to unnecessary spillage to the C-TCAM.
This may result in reduced scale and performance.

Patch #1 includes the delta bits in the rule's key to avoid the above
mentioned problem.

Patch #2 adds a tracepoint when a rule is inserted into the C-TCAM.

Patches #3-#5 add test cases to make sure unnecessary spillage into the
C-TCAM does not occur.

With recent fix in C-TCAM spillage for delta masks, the test stops to be
falsely positive. So fix it not to use delta by adding src_ip bits to the
masks. Alongside with that, use C-TCAM spill trace to see when the
spillage actually happens.

Jiri Pirko cb56e21467 mlxsw: spectrum_acl: Include delta bits into hashtable key
Currently only ERP mask masked bits in key are considered for
the hashtable key. That leads to false negative collisions
and fallbacks to C-TCAM in case two keys differ only in delta bits.

Fix this by taking full encoded key as a hashtable key,
including delta bits.

Xin Long says:

====================
sctp: support SCTP_FUTURE/CURRENT/ALL_ASSOC

This patchset adds the support for 3 assoc_id constants: SCTP_FUTURE_ASSOC
SCTP_CURRENT_ASSOC, SCTP_ALL_ASSOC, described in rfc6458#section-7.2:

   All socket options set on a one-to-one style listening socket also
   apply to all future accepted sockets.  For one-to-many style sockets,
   often a socket option will pass a structure that includes an assoc_id
   field.  This field can be filled with the association identifier of a
   particular association and unless otherwise specified can be filled
   with one of the following constants:

   SCTP_FUTURE_ASSOC:  Specifies that only future associations created
      after this socket option will be affected by this call.

   SCTP_CURRENT_ASSOC:  Specifies that only currently existing
      associations will be affected by this call, and future
      associations will still receive the previous default value.

   SCTP_ALL_ASSOC:  Specifies that all current and future associations
      will be affected by this call.

The functions for many other sockopts that use assoc_id also need to be
updated accordingly.

devlink: Add configuration parameters support for devlink_port

This patchset adds support for configuration parameters setting through
devlink_port.  Each device registers supported configuration parameters
table.

The user can retrieve data on these parameters by
"devlink port param show" command and can set new value to a
parameter by "devlink port param set" command.
All configuration modes supported by devlink_dev are supported
by devlink_port also.

Command examples and output:

pci/0000:3b:00.0/0:
  name wake-on-lan type generic
    values:
      cmode permanent value false

pci/0000:3b:00.1/1:
  name wake-on-lan type generic
    values:
      cmode permanent value false

pci/0000:af:00.0/0:
  name wake-on-lan type generic
    values:
      cmode permanent value true

pci/0000:3b:00.0/0:
  name wake-on-lan type generic
    values:
      cmode permanent value false

There is difference of opinion on adding WOL parameter to devlink, between
Jakub Kicinski and Michael Chan.

Quote from Jakud Kicinski:
********
As explained previously I think it's a very bad idea to add existing
configuration options to devlink, just because devlink has the ability
to persist the setting in NVM.  Especially that for WoL you have to get
the link up so you potentially have all link config stuff as well.  And
that n-tuple filters are one of the WoL options, meaning we'd need the
ability to persist n-tuple filters via devlink.

The effort would be far better spent helping with migrating ethtool to
netlink, and allowing persisting there.

I have not heard any reason why devlink is a better fit.  I can imagine
you're just doing it here because it's less effort for you since
ethtool is not yet migrated.
********

Quote from Michael Chan:
********
The devlink's WoL parameter is a persistent WoL parameter stored in the
NIC's NVRAM. It is different from ethtool's WoL parameter in a number of
ways. ethtool WoL is not persistent over AC power cycle and is considered
OS-present WoL. As such, ethtool WoL can use a more sophisticated pattern
including n-tuple with IP address in addition to the more basic types
(e.g. magic packet). Whereas OS-absent power up WoL should only include
magic packet and other simple types. The devlink WoL setting does not have
to match the ethtool WoL setting. The card will autoneg up to the speed
supported by Vaux so no special devlink link setting is needed.
********

Future expansion of WOL parameter to devlink:
********
Add an additional flag to support additional setting to address link settings.
This will allow attributes to support both runtime and persistent
configuration.
********

v7->v8:
* Re-ordered function definitions.
* Append with "Acked-by: Jiri Pirko <jiri@mellanox.com>" to first 3 patches.
* Add missing devlink_port_param_driverinit_value_get() declaration.

v6->v7:
* Remove RFC tag from the patch-set.

v5->v6:
* Replace '-' with '*' in cover letter to avoid cutoff by git.

v4->v5:
* Added quotes from Jakub Kicinski and Michael chan on devlink's WOL
  parameter in the cover letter.

v3->v4:
* Update changes done from v2 to v3 version in individual patch
  descriptions.

v2->v3:
Make following changes as per suggestions from Jiri Pirko and
Michal Kubecek.
* Add a helper __devlink_params_register() with common code used by
  both devlink_params_register() and devlink_port_params_register().
* Define only WOL types used now and define them as bitfield, so that
  mutliple WOL types can be enabled upon power on.
* Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with
  previous definitions.
* Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be
  symmetrical with ethtool WOL definitions.
* Modify bnxt_dl_wol_validate(), to throw error message when user gives
  value other than DEVLINK_PARAM_WAKE_MAGIC or to disable WOL.
* Use netdev_err() instead of netdev_warn(), when devlink_port_register()
  and devlink_port_params_register() returns error. Also, don't log rc
  in this message.

v1->v2:
Make following changes as per suggestions from Jiri Pirko.
* Remove separate enum devlink_port_param_generic_id for port params.
  Instead club it with existing device params. Accordingly refactor
  remaining patchset.
* Move INIT_LIST_HEAD of port param_list to devlink_port_register()
* Add a helper devlink_param_verify() to be used for both
  devlink_params_register() and devlink_port_params_register().
* Add a helper __devlink_params_unregister() for common code in
  devlink_params_unregister() and devlink_port_params_unregister().
* Move DEVLINK_CMD_PORT_PARAM_XXX definitions to the end of the enum.
* Split the patches for devlink_port_param_driverinit_value_get() and
  devlink_port_param_driverinit_value_set() into separate patches.
* define DEVLINK_PARAM_GENERIC_ID_WOL type as u8 and define enum for
  different types of WOL. Accordingly modify bnxt_en patch to validate
  wol type.

- Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with
  previous definitions.
- Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be
  symmetrical with ethtool WOL definitions.

Vasundhara Volam c1e5786d67 devlink: Add devlink notifications support for port params
Add notification call for devlink port param set, register and unregister
functions.
Add devlink_port_param_value_changed() function to enable the driver notify
devlink on value change. Driver should use this function after value was
changed on any configuration mode part to driverinit.

v7->v8:
Order devlink_port_param_value_changed() definitions followed by
devlink_param_value_changed()

 1) Need to save away the IV across tls async operations, from Dave
    Watson.

 2) Upon successful packet processing, we should liberate the SKB with
    dev_consume_skb{_irq}(). From Yang Wei.

 3) Only apply RX hang workaround on effected macb chips, from Harini
    Katakam.

 4) Dummy netdev need a proper namespace assigned to them, from Josh
    Elsasser.

 5) Some paths of nft_compat run lockless now, and thus we need to use a
    proper refcnt_t. From Florian Westphal.

 6) Avoid deadlock in mlx5 by doing IRQ locking, from Moni Shoua.

 7) netrom does not refcount sockets properly wrt. timers, fix that by
    using the sock timer API. From Cong Wang.

    Westphal.

 9) Missing xfrm hash generation bump, also from Florian.

10) Missing of_node_put() in hns driver, from Yonglong Liu.

Gustavo A. R. Silva c829f5f52d cxgb4: cxgb4_tc_u32: use struct_size() in kvzalloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:

instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

Yang Wei 0f0ed8282e net: b44: replace dev_kfree_skb_xxx by dev_consume_skb_xxx for drop profiles
The skb should be freed by dev_consume_skb_any() in b44_start_xmit()
when bounce_skb is used. The skb is be replaced by bounce_skb, so the
original skb should be consumed(not drop).

dev_consume_skb_irq() should be called in b44_tx() when skb xmit
done. It makes drop profiles(dropwatch, perf) more friendly.
