Commit 56df345917 ("i40e: Remove circular header dependencies and fix
headers") redistributed a number of includes from one large header file
to the locations they were needed. In some environments, types.h is not
included and causing compile issues. The driver should not rely on
implicit inclusion from other locations; explicitly include it to these
files.
Snippet of issue. Entire log can be seen through the Closes: link.

According to the Intel Software Manual for I225, Section 7.5.2.7,
hicredit should be multiplied by the constant link-rate value, 0x7736.
Currently, the old constant link-rate value, 0x7735, from the boards
supported on igb are being used, most likely due to a copy'n'paste, as
the rest of the logic is the same for both drivers.

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.
Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.

Commit 3116f59c12 ("i40e: fix use-after-free in
i40e_sync_filters_subtask()") avoided use-after-free issues,
by increasing refcount during update the VSI filter list to
the HW. However, it missed the unicast situation.
When deleting an unicast FDB entry, the i40e driver will release
the mac_filter, and i40e_service_task will concurrently request
firmware to add the mac_filter, which will lead to the following
use-after-free issue.
Fix again for both netdev->uc and netdev->mc.

Add const modifier to function parameters and variables where appropriate

The reason for starting the change is that read-only pointers should be
marked as const when possible to allow for smoother and more optimal code

The ice_vf_create_vsi() function and its VF ops helper introduced by commit
a4c785e8162e ("ice: convert vf_ops .vsi_rebuild to .create_vsi") are used
during an individual VF reset to re-create the VSI. This was done in order
to ensure that the VSI gets properly reconfigured within the hardware.
This is somewhat heavy handed as we completely release the VSI memory and
structure, and then create a new VSI. This can also potentially force a
change of the VSI index as we will re-use the first open slot in the VSI
array which may not be the same.
As part of implementing devlink reload, commit 6624e780a5 ("ice: split
ice_vsi_setup into smaller functions") split VSI setup into smaller
functions, introducing both ice_vsi_cfg() and ice_vsi_decfg() which can be
used to configure or deconfigure an existing software VSI structure.
Rather than completely removing the VSI and adding a new one using the
.create_vsi() VF operation, simply use ice_vsi_decfg() to remove the
current configuration. Save the VSI type and then call ice_vsi_cfg() to
reconfigure the VSI as the same type that it was before.
The existing reset logic assumes that all hardware filters will be removed,
so also call ice_fltr_remove_all() before re-configuring the VSI.
This new operation does not re-create the VSI, so rename it to
ice_vf_reconfig_vsi().
The new approach can safely share the exact same flow for both SR-IOV VFs
as well as the Scalable IOV VFs being worked on. This uses less code and is
a better abstraction over fully deleting the VSI and adding a new one.

Introduce new capability - Low Latency Timestamping with Interrupt.
On supported devices, driver can request a single timestamp from FW
without polling the register afterwards. Instead, FW can issue
a dedicated interrupt when the timestamp was read from the PHY register
and its value is available to read from the register.
This eliminates the need of bottom half scheduling, which results in
minimal delay for timestamping.
For this mode, allocate TS indices sequentially, so that timestamps are
always completed in FIFO manner.

Dpll subsystem is using the value in 0.001ps, raw value is adjusted
before providing it to the user.
The user can observe the value of phase offset with response to
`pin-get` netlink message of dpll subsystem for an active pin:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
Where example of correct response would be:
{'board-label': 'C827_0-RCLKA',
'capabilities': 6,
'clock-id': 4658613174691613800,
'frequency': 1953125,

'phase-adjust': 0,
'phase-adjust-max': 16723,
'phase-adjust-min': -16723,

Provided phase-offset value (-42930) shall be divided by the user with
DPLL_PHASE_OFFSET_DIVIDER to get actual value of -42.930 ps.
Before the fix, the response was not correct:

Size of the virtchnl2_rss_key struct should be 7 bytes but the
compiler introduces a padding byte for the structure alignment.
This results in idpf sending an additional byte of memory to the device
control plane than the expected buffer size. As the control plane
enforces virtchnl message size checks to validate the message,
set RSS key message fails resulting in the driver load failure.
Remove implicit compiler padding by using "__packed" structure
attribute for the virtchnl2_rss_key struct.
Also there is no need to use __DECLARE_FLEX_ARRAY macro for the
'key_flex' struct field. So drop it.

idpf_ring::skb serves only for keeping an incomplete frame between
several NAPI Rx polling cycles, as one cycle may end up before
processing the end of packet descriptor. The pointer is taken from
the ring onto the stack before entering the loop and gets written
there after the loop exits. When inside the loop, only the onstack
pointer is used.
For some reason, the logics is broken in the singleq mode, where the
pointer is taken from the ring each iteration. This means that if a
frame got fragmented into several descriptors, each fragment will have
its own skb, but only the last one will be passed up the stack
(containing garbage), leaving the rest leaked.
Then, on ifdown, rxq::skb is being freed only in the splitq mode, while
it can point to a valid skb in singleq as well. This can lead to a yet
another skb leak.
Just don't touch the ring skb field inside the polling loop, letting
the onstack skb pointer work as expected: build a new skb if it's the
first frame descriptor and attach a frag otherwise. On ifdown, free
rxq::skb unconditionally if the pointer is non-NULL.

Tony Nguyen says:
====================
intel: use bitfield operations
Jesse Brandeburg says:
After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET(). It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.
This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.
Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.
The second patch just adds all the new #includes in one go.
The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.
The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.

pull-request: bpf-next 2023-12-18
This PR is larger than usual and contains changes in various parts
of the kernel.
The main changes are:
1) Fix kCFI bugs in BPF, from Peter Zijlstra.
End result: all forms of indirect calls from BPF into kernel
and from kernel into BPF work with CFI enabled. This allows BPF
to work with CONFIG_FINEIBT=y.
2) Introduce BPF token object, from Andrii Nakryiko.
It adds an ability to delegate a subset of BPF features from privileged
daemon (e.g., systemd) through special mount options for userns-bound
BPF FS to a trusted unprivileged application. The design accommodates
suggestions from Christian Brauner and Paul Moore.
Example:
$ sudo mkdir -p /sys/fs/bpf/token
$ sudo mount -t bpf bpffs /sys/fs/bpf/token \
-o delegate_cmds=prog_load:MAP_CREATE \
-o delegate_progs=kprobe \
-o delegate_attachs=xdp
3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei.
- Complete precision tracking support for register spills
- Fix verification of possibly-zero-sized stack accesses
- Fix access to uninit stack slots
- Track aligned STACK_ZERO cases as imprecise spilled registers.
It improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs.
- Fix verifier retval logic
4) Support for VLAN tag in XDP hints, from Larysa Zaremba.
5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu.
End result: better memory utilization and lower I$ miss for calls to BPF
via BPF trampoline.
6) Fix race between BPF prog accessing inner map and parallel delete,
from Hou Tao.
7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu.
It allows BPF interact with IPSEC infra. The intent is to support
software RSS (via XDP) for the upcoming ipsec pcpu work.
Experiments on AWS demonstrate single tunnel pcpu ipsec reaching
line rate on 100G ENA nics.
8) Expand bpf_cgrp_storage to support cgroup1 non-attach, from Yafang Shao.
9) BPF file verification via fsverity, from Song Liu.
It allows BPF progs get fsverity digest.

Most of idpf correctly uses FIELD_GET and FIELD_PREP, but a couple spots
were missed so fix those.
Automated conversion with coccinelle script and manually fixed up,
including audits for opportunities to convert to {get,encode,replace}
bits functions.
Add conversions to le16_get/encode/replace_bits where appropriate. And
in one place fix up a cast from a u16 to a u16.

It was found while doing further testing of the previous commit
fbf32a9bab91 ("ice: field get conversion") that one of the FIELD_GET
conversions should really be a FIELD_PREP. The previous code was styled
as a match to the FIELD_GET conversion, which always worked because the
shift value was 0. The code makes way more sense as a FIELD_PREP and
was in fact the only FIELD_GET with two constant arguments in this
series.
Didn't squash this patch to make it easier to call out the
(non-impactful) bug.

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.
Do the same for the VLAN EMODE defines as well.

Several places I changed to OR into a single variable with |= instead of

A local variable vmvf_and_timeout was created and used to avoid multiple
logical ORs being __le16 converted, which shortened some lines and makes
the code cleaner.
