net/af_iucv: don't track individual TX skbs for TRANS_HIPER sockets
Stop maintaining the skb_send_q list for TRANS_HIPER sockets. Not only is it extra overhead, but keeping around a list of skb clones means that we later also have to match the ->sk_txnotify() calls against these clones and free them accordingly. The current matching logic (comparing the skbs' shinfo location) is frustratingly fragile, and breaks if the skb's head is mangled in any sort of way while passing from dev_queue_xmit() to the device's HW queue. Also adjust the interface for ->sk_txnotify(), to make clear that we don't actually care about any skb internals.

net/af_iucv: count packets in the xmit path
The TX code keeps track of all skbs that are in-flight but haven't
actually been sent out yet. For native IUCV sockets that's not a huge
deal, but with TRANS_HIPER sockets it would be much better if we
didn't need to maintain a list of skb clones.
Note that we actually only care about the _count_ of skbs in this stage
of the TX pipeline. So as prep work for removing the skb tracking on
TRANS_HIPER sockets, keep track of the skb count in a separate variable
and pair any list {enqueue, unlink} with a count {increment, decrement}.
Then replace all occurences where we currently look at the skb list's
fill level.

s390/qeth: make cast type selection for af_iucv skbs robust
As part of the TX queue selection for af_iucv skbs, qeth_l3_get_cast_type_rcu() ends up calling qeth_get_ether_cast_type(). Which is rather fragile, since such skbs don't have a proper ETH header and we rely on it being zeroed out in the right places. Add a separate case for ETH_P_AF_IUCV instead that does the right thing. When later building the HW header for such skbs, don't hard-code the cast type but follow the same path as for other protocol types. Here the cast type should naturally come from the skb's queue mapping.

Merge branch 'net-ipa-hardware-pipeline-cleanup-fixes'
Alex Elder says: ==================== net: ipa: hardware pipeline cleanup fixes There is a procedure currently referred to as a "tag process" that is performed to clear the IPA hardware pipeline--either at the time of a modem crash, or when suspending modem GSI channels. One thing done in this procedure is issuing a command that sends a data packet originating from the AP->command TX endpoint, destined for the AP<-LAN RX (default) endpoint. And although we currently wait for the send to complete, we do *not* wait for the packet to be received. But the pipeline can't be assumed clear until we have actually received this packet. This series addresses this by detecting when the pipeline-clearing packet has been received, and using a completion to allow a waiter to know when that has happened. This uses the IPA status capability (which sends an extra status buffer for certain packets). It also uses the ability to supply a "tag" with a packet, which will be delivered with the packet's status buffer. We tag the data packet that's sent to clear the pipeline, and use the receipt of a status buffer associated with a tagged packet to determine when that packet has arrived. "Tag status" just desribes one aspect of this procedure, so some symbols are renamed to be more like "pipeline clear" so they better describe the larger purpose. Finally, two functions used in this code don't use their arguments, so those arguments are removed. ==================== Link: https://lore.kernel.org/r/20210126185703.29087-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: ipa: don't pass size to ipa_cmd_transfer_add()
The only time we transfer data (rather than issuing a command) out of the AP->command TX endpoint is when we're clearing the hardware pipeline. All that's needed is a "small" data buffer, and its contents aren't even important. For convenience, we just transfer a command structure in this case (it's already mapped for DMA). The TRE is added to a transaction using ipa_cmd_ip_tag_status_add(), but we ignore the size value provided to that function. So just get rid of the size argument.

net: ipa: signal when tag transfer completes
There are times, such as when the modem crashes, when we issue commands to clear the IPA hardware pipeline. These commands include a data transfer command that delivers a small packet directly to the default (AP<-LAN RX) endpoint. The places that do this wait for the transactions that contain these commands to complete, but the pipeline can't be assumed clear until the sent packet has been *received*. The small transfer will be delivered with a status structure, and that status will indicate its tag is valid. This is the only place we send a tagged packet, so we use the tag to determine when the pipeline clear packet has arrived. Add a completion to the IPA structure to to be used to signal the receipt of a pipeline clear packet. Create a new function ipa_cmd_pipeline_clear_wait() that will wait for that completion. Reinitialize the completion whenever pipeline clear commands are added to a transaction. Extend ipa_endpoint_status_tag() to check whether a packet whose status contains a valid tag was sent from the AP->command TX endpoint, and if so, signal the new IPA completion. Have all callers of ipa_cmd_pipeline_clear_add() wait for the pipeline clear indication after the transaction that clears the pipeline has completed.

The name is related to one of the commands issued when doing this, but it doesn't really convey the overall purpose of taking this action.

net: adjust net_device layout for cacheline usage
The current layout of net_device is not optimal for cacheline usage. The member adj_list.lower linked list is split between cacheline 2 and 3. The ifindex is placed together with stats (struct net_device_stats), although most modern drivers don't update this stats member. The members netdev_ops, mtu and hard_header_len are placed on three different cachelines. These members are accessed for XDP redirect into devmap, which were noticeably with perf tool. When not using the map redirect variant (like TC-BPF does), then ifindex is also used, which is placed on a separate fourth cacheline. These members are also accessed during forwarding with regular network stack. The members priv_flags and flags are on fast-path for network stack transmit path in __dev_queue_xmit (currently located together with mtu cacheline). This patch creates a read mostly cacheline, with the purpose of keeping the above mentioned members on the same cacheline. Some netdev_features_t members also becomes part of this cacheline, which is on purpose, as function netif_skb_features() is on fast-path via validate_xmit_skb().

mlx5 subfunction support
Parav Pandit Says:
=================
This patchset introduces support for mlx5 subfunction (SF).
A subfunction is a lightweight function that has a parent PCI function on
which it is deployed. mlx5 subfunction has its own function capabilities
and its own resources. This means a subfunction has its own dedicated
queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from
the parent PCI function.
When subfunction is RDMA capable, it has its own QP1, GID table and rdma
resources neither shared nor stolen from the parent PCI function.
A subfunction has dedicated window in PCI BAR space that is not shared
with the other subfunctions or parent PCI function. This ensures that all
class devices of the subfunction accesses only assigned PCI BAR space.
A Subfunction supports eswitch representation through which it supports tc
offloads. User must configure eswitch to send/receive packets from/to
subfunction port.
Subfunctions share PCI level resources such as PCI MSI-X IRQs with
their other subfunctions and/or with its parent PCI function.
Patch summary:
--------------
Patch 1 to 4 prepares devlink
patch 5 to 7 mlx5 adds SF device support
Patch 8 to 11 mlx5 adds SF devlink port support
Patch 12 and 14 adds documentation
Patch-1 prepares code to handle multiple port function attributes
Patch-2 introduces devlink pcisf port flavour similar to pcipf and pcivf
Patch-3 adds port add and delete driver callbacks
Patch-4 adds port function state get and set callbacks
Patch-5 mlx5 vhca event notifier support to distribute subfunction
state change notification
Patch-6 adds SF auxiliary device
Patch-7 adds SF auxiliary driver
Patch-8 prepares eswitch to handler SF vport
Patch-9 adds eswitch helpers to add/remove SF vport
Patch-10 implements devlink port add/del callbacks
Patch-11 implements devlink port function get/set callbacks
Patch-12 to 14 adds documentation
Patch-12 added mlx5 port function documentation
Patch-13 adds subfunction documentation
Patch-14 adds mlx5 subfunction documentation
Subfunction support is discussed in detail in RFC [1] and [2].
RFC [1] and extension [2] describes requirements, design and proposed
plumbing using devlink, auxiliary bus and sysfs for systemd/udev
support. Functionality of this patchset is best explained using real
examples further below.
overview:
--------
A subfunction can be created and deleted by a user using devlink port
add/delete interface.
A subfunction can be configured using devlink port function attribute
before its activated.
When a subfunction is activated, it results in an auxiliary device on
the host PCI device where it is deployed. A driver binds to the
auxiliary device that further creates supported class devices.
example subfunction usage sequence:

mlx5 subfunction support
Parav Pandit says:
This patchset introduces support for mlx5 subfunction (SF).
A subfunction is a lightweight function that has a parent PCI function on
which it is deployed. mlx5 subfunction has its own function capabilities
and its own resources. This means a subfunction has its own dedicated
queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from
the parent PCI function.
When subfunction is RDMA capable, it has its own QP1, GID table and rdma
resources neither shared nor stolen from the parent PCI function.
A subfunction has dedicated window in PCI BAR space that is not shared
with the other subfunctions or parent PCI function. This ensures that all
class devices of the subfunction accesses only assigned PCI BAR space.
A Subfunction supports eswitch representation through which it supports tc
offloads. User must configure eswitch to send/receive packets from/to
subfunction port.
Subfunctions share PCI level resources such as PCI MSI-X IRQs with
their other subfunctions and/or with its parent PCI function.
Subfunction support is discussed in detail in RFC [1] and [2].
RFC [1] and extension [2] describes requirements, design and proposed
plumbing using devlink, auxiliary bus and sysfs for systemd/udev
support. Functionality of this patchset is best explained using real
examples further below.
overview:
--------
A subfunction can be created and deleted by a user using devlink port
add/delete interface.
A subfunction can be configured using devlink port function attribute
before its activated.
When a subfunction is activated, it results in an auxiliary device on
the host PCI device where it is deployed. A driver binds to the
auxiliary device that further creates supported class devices.
example subfunction usage sequence:
-----------------------------------
Change device to switchdev mode:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
Add a devlink port of subfunction flavour:
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Configure mac address of the port function:
$ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88
Now activate the function:
$ devlink port function set ens2f0npf0sf88 state active
Now use the auxiliary device and class devices:
$ devlink dev show

net: sfp: add mode quirk for GPON module Ubiquiti U-Fiber Instant
The Ubiquiti U-Fiber Instant SFP GPON module has nonsensical information stored in its EEPROM. It claims to support all transceiver types including 10G Ethernet. Clear all claimed modes and set only 1000baseX_Full, which is the only one supported. This module has also phys_id set to SFF, and the SFP subsystem currently does not allow to use SFP modules detected as SFFs. Add exception for this module so it can be detected as supported. This change finally allows to detect and use SFP GPON module Ubiquiti U-Fiber Instant on Linux system. EEPROM content of this SFP module is (where XX is serial number): 00: 02 04 0b ff ff ff ff ff ff ff ff 03 0c 00 14 c8 ???........??.?? 10: 00 00 00 00 55 42 4e 54 20 20 20 20 20 20 20 20 ....UBNT 20: 20 20 20 20 00 18 e8 29 55 46 2d 49 4e 53 54 41 .??)UF-INSTA 30: 4e 54 20 20 20 20 20 20 34 20 20 20 05 1e 00 36 NT 4 ??.6 40: 00 06 00 00 55 42 4e 54 XX XX XX XX XX XX XX XX .?..UBNTXXXXXXXX 50: 20 20 20 20 31 34 30 31 32 33 20 20 60 80 02 41 140123 `??A Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

mlxsw: spectrum_span: Do not overwrite policer configuration
The purpose of the delayed work in the SPAN module is to potentially
update the destination port and various encapsulation parameters of SPAN
agents that point to a VLAN device or a GRE tap. The destination port
can change following the insertion of a new route, for example.
SPAN agents that point to a physical port or the CPU port are static and
never change throughout the lifetime of the SPAN agent. Therefore, skip
over them in the delayed work.
This fixes an issue where the delayed work overwrites the policer
that was set on a SPAN agent pointing to the CPU. Modifying the delayed
work to inherit the original policer configuration is error-prone, as
the same will be needed for any new parameter.
Fixes:

A set of PI futex fixes:
- Address a longstanding issue where the user space part of the PI futex
is not writeable. The kernel returns with inconsistent state which can
in the worst case result in a UAF of a tasks kernel stack. The solution
is to establish consistent kernel state which makes future operations
on the futex fail because user space and kernel space state are
inconsistent. Not a problem as PI futexes fundamentaly require a
functional RW mapping and if user space pulls the rug under it, then it
can keep the pieces it asked for.
- Address an issue where the return value is incorrect in case that the
futex was acquired after a timeout/signal made the waiter drop out of
the rtmutex wait. In one of the corner cases the kernel returned an
error code despite having successfully acquired the futex.

ARM: SoC fixes for v5.11, part 2
These are the current arm-soc bug fixes for linux-5.11. I already merged
a larger set that just came in during the past three days but has not
had much exposure in linux-next, so these are the ones I merged last week.
Most of these are for the NXP i.MX platform (descriptions from their
pull request):
- Fix pcf2127 reset for imx7d-flex-concentrator board.
- Fix i.MX6 suspend with Thumb-2 kernel.
- Fix ethernet-phy address issue on imx6qdl-sr-som board.
- Fix GPIO3 `gpio-ranges` on i.MX8MP.
- Select SOC_BUS for IMX_SCU driver to fix build issue.
- Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
#pwm-cells conversion.
- Fix duplicated bus node name for i.MX8MN SoC.
- Fix reset register offset on LS1028A SoC.
- Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
index consistent with previous kernel version.
- Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
with i.MX8M SoC driver.
- Fix typos with status property on imx6qdl-kontron-samx6i board.
- Fix duplicated regulator-name on imx6qdl-gw52xx board.
Aside from i.MX, the bugfixes are all over the place:
- Coccinelle found a refcount imbalance on integrator
- defconfig fix for TI K3
- A boot regression fix for ST ux500
- A code preemption fix for the optee driver
- USB DMA regression on Broadcom Stingray
- A bogus boot time warning fix for at91 code

net: dsa: rtl8366rb: standardize init jam tables
In the rtl8366rb driver there are some jam tables which contain undocumented values. While trying to understand what these tables actually do, I noticed a discrepancy in how one of those was treated. Most of them were plain u16 arrays, while the ethernet one was an u16 matrix. By looking at the vendor's droplets of source code these tables came from, I found out that they were all originally u16 matrixes. This commit standardizes the jam tables, turning them all into jam_tbl_entry arrays. Each entry contains 2 u16 values. This change makes it easier to understand how the jam tables are used and also makes it possible for a single function to handle all of them, removing some duplicated code.
