Number of RVU PFs on CN20K silicon have increased to 96 from maximum
of 32 that were supported on earlier silicons. Every RVU PF and VF is
identified by HW using a 16bit PF_FUNC value. Due to the change in
Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed.
This patch handles the change by using helper functions(using silicon
check) to use PF,VF masks and shifts to support both new silicon CN20K,
OcteonTx series. These helper functions are used in different modules.
Also moved the NIX AF register offset macros to other files which
will be posted in coming patches.

Move netpoll_print_options() from net/core/netpoll.c to
drivers/net/netconsole.c and make it static. This function is only used
by netconsole, so there's no need to export it or keep it in the public
netpoll API.
This reduces the netpoll API surface and improves code locality
by keeping netconsole-specific functionality within the netconsole
driver.

Move netpoll_parse_ip_addr() and netpoll_parse_options() from the generic
netpoll module to the netconsole module where they are actually used.
These functions were originally placed in netpoll but are only consumed by
netconsole. This refactoring improves code organization by:
- Removing unnecessary exported symbols from netpoll
- Making netpoll_parse_options() static (no longer needs global visibility)
- Reducing coupling between netpoll and netconsole modules
The functions remain functionally identical - this is purely a code
reorganization to better reflect their actual usage patterns. Here are
the changes:
1) Move both functions from netpoll to netconsole
2) Add static to netpoll_parse_options()
3) Removed the EXPORT_SYMBOL()
PS: This diff does not change the function format, so, it is easy to
review, but, checkpatch will not be happy. A follow-up patch will
address the current issues reported by checkpatch.

Move np_info(), np_err(), and np_notice() macros from internal
implementation to the public netpoll header file to make them
available for use by netpoll consumers.
These logging macros provide consistent formatting for netpoll-related
messages by automatically prefixing log output with the netpoll instance
name.
The goal is to use the exact same format that is being displayed today,
instead of creating something netconsole-specific.

We mux multiple calls to the drivers via the .get_nfc and .set_nfc
callbacks. This is slightly inconvenient to the drivers as they
have to de-mux them back. It will also be awkward for netlink code
to construct struct ethtool_rxnfc when it wants to get info about
RX Flow Hash, from the RSS module.
Add dedicated driver callbacks. Create struct ethtool_rxfh_fields
which contains only data relevant to RXFH. Maintain the names of
the fields to avoid having to heavily modify the drivers.
For now support both callbacks, once all drivers are converted
ethtool_*et_rxfh_fields() will stop using the rxnfc callbacks.

sk->sk_prot->sock_is_readable is a valid function pointer when sk resides
in a sockmap. After the last sk_psock_put() (which usually happens when
socket is removed from sockmap), sk->sk_prot gets restored and
sk->sk_prot->sock_is_readable becomes NULL.
This makes sk_is_readable() racy, if the value of sk->sk_prot is reloaded
after the initial check. Which in turn may lead to a null pointer
dereference.
Ensure the function pointer does not turn NULL after the check.

Add a new function, netif_subqueue_sent, which is a wrapper for
netdev_tx_sent_queue.
Drivers that use the subqueue variant macros, netif_subqueue_xxx,
identify queue by index and are not required to obtain
struct netdev_queue explicitly.
Such drivers still need to call netdev_tx_sent_queue which is a
counterpart of netif_subqueue_completed_wake. Allowing drivers to use a
subqueue variant for this purpose improves their code consistency by
always referring to queue by its index.

====================
Intel Wired LAN Driver Updates 2025-06-09 (ice, i40e, ixgbe, iavf)
Jake moves from individual virtchnl RSS configuration values, for ice,
i40e, and iavf, to a common libie location and values.
Martyna and Dawid add counters for link_down_events to ice, i40e, and
ixgbe drivers. The counter increments only on actual physical link-down
events visible to the PHY. It does not increment when the user performs
a software-only interface down/up (e.g. ip link set dev down).
The counter does increment in cases where the interface is reinitialized
in a way that causes a real link drop - such as eg. when attaching
an XDP program, reconfiguring channels, or toggling certain priv-flags.
For ice:
Arkadiusz and Karol separate PTP and DPLL functionality to their
respective APIs.
Michal adds a separate handler for Flow Director command processing.
For iavf:
Ahmed converts driver to utilize core's IRQ affinity API.
For ixgbe:
Alok Tiwari fixes issues with some comments; typos, copy/paste errors,
etc.

A decade ago commit 6d08acd2d3 ("in6: fix conflict with glibc")
hid the definitions of IPV6 options, because GCC was complaining
about duplicates. The commit did not list the warnings seen, but
trying to recreate them now I think they are (building iproute2):
In file included from ./include/uapi/rdma/rdma_user_cm.h:39,
from rdma.h:16,
from res.h:9,
from res-ctx.c:7:
../include/uapi/linux/in6.h:171:9: warning: ‘IPV6_ADD_MEMBERSHIP’ redefined
171 | #define IPV6_ADD_MEMBERSHIP 20

In file included from /usr/include/netinet/in.h:37,

/usr/include/bits/in.h:234:10: note: this is the location of the previous definition
234 | # define IPV6_DROP_MEMBERSHIP IPV6_LEAVE_GROUP
| ^~~~~~~~~~~~~~~~~~~~
Compilers don't complain about redefinition if the defines
are identical, but here we have the kernel using the literal
value, and glibc using an indirection (defining to a name
of another define, with the same numerical value).
Problem is, the commit in question hid all the IPV6 socket
options, and glibc has a pretty sparse list. For instance
it lacks Flow Label related options. Willem called this out
in commit 3fb321fde2 ("selftests/net: ipv6 flowlabel"):
/* uapi/glibc weirdness may leave this undefined */
#ifndef IPV6_FLOWINFO
#define IPV6_FLOWINFO 11
#endif
More interestingly some applications (socat) use
a #ifdef IPV6_FLOWINFO to gate compilation of thier
rudimentary flow label support. (For added confusion
socat misspells it as IPV4_FLOWINFO in some places.)
Hide only the two defines we know glibc has a problem
with. If we discover more warnings we can hide more
but we should avoid covering the entire block of
defines for "IPV6 socket options".

The Intel i40e, iavf, and ice drivers all include a definition of the
packet classifier filter types used to program RSS hash enable bits. For
i40e, these bits are used for both the PF and VF to configure the PFQF_HENA
and VFQF_HENA registers.
For ice and iAVF, these bits are used to communicate the desired hash
enable filter over virtchnl via its struct virtchnl_rss_hashena. The
virtchnl.h header makes no mention of where the bit definitions reside.
Maintaining a separate copy of these bits across three drivers is
cumbersome. Move the definition to libie as a new pctype.h header file.
Each driver can include this, and drop its own definition.
The ice implementation also defined a ICE_AVF_FLOW_FIELD_INVALID, intending
to use this to indicate when there were no hash enable bits set. This is
confusing, since the enumeration is using bit positions. A value of 0
*should* indicate the first bit. Instead, rewrite the code that uses
ICE_AVF_FLOW_FIELD_INVALID to just check if the avf_hash is zero. From
context this should be clear that we're checking if none of the bits are
set.
The values are kept as bit positions instead of encoding the BIT_ULL
directly into their value. While most users will simply use BIT_ULL
immediately, i40e uses the macros both with BIT_ULL and test_bit/set_bit
calls.

i40e, ice, and iAVF all use 'hena' as a shorthand for the "hash enable"
configuration. This comes originally from the X710 datasheet 'xxQF_HENA'
registers. In the context of the registers the meaning is fairly clear.
However, on its own, hena is a weird name that can be more difficult to
understand. This is especially true in ice. The E810 hardware doesn't even
have registers with HENA in the name.
Replace the shorthand 'hena' with 'hashcfg'. This makes it clear the
variables deal with the Hash configuration, not just a single boolean
on/off for all hashing.
Do not update the register names. These come directly from the datasheet
for X710 and X722, and it is more important that the names can be searched.

- Fix regression of waiting a long time on updating trace event filters
When the faultable trace points were added, it needed task trace RCU
synchronization. This was added to the tracepoint_synchronize_unregister()
function. The filter logic always called this function whenever it
updated the trace event filters before freeing the old filters.
This increased the time of "trace-cmd record" from taking 13 seconds
to running over 2 minutes to complete.

time back down to 13 seconds.
- Fix ring_buffer_subbuf_order_set() error path lock protection
The error path of the ring_buffer_subbuf_order_set() released the
mutex too early and allowed subsequent accesses to setting the
subbuffer size to corrupt the data and cause a bug.
By moving the mutex locking to the end of the error path, it prevents
the reentrant access to the critical data and also allows the function
to convert the taking of the mutex over to the guard() logic.
- Remove unused power management clock events
The clock events were added in 2010 for power management. In 2011
arm used them. In 2013 the code they were used in was removed.
These events have been wasting memory since then.

Intention for MNT_LOCKED had always been to protect the internal
mountpoints within a subtree that got copied across the userns boundary,
not the mountpoint that tree got attached to - after all, it _was_
exposed before the copying.
For roots of secondary copies that is enforced in attach_recursive_mnt() -
MNT_LOCKED is explicitly stripped for those. For the root of primary
copy we are almost always guaranteed that MNT_LOCKED won't be there,
so attach_recursive_mnt() doesn't bother. Unfortunately, one call
chain got overlooked - triggering e.g. NFS referral will have the
submount inherit the public flags from parent; that's fine for such
things as read-only, nosuid, etc., but not for MNT_LOCKED.
This is particularly pointless since the mount attached by finish_automount()
is usually expirable, which makes any protection granted by MNT_LOCKED
null and void; just wait for a while and that mount will go away on its own.
Include MNT_LOCKED into the set of flags to be ignored by do_add_mount() - it
really is an internal flag.

in 2010. In 2011 they were used by the arm architecture but removed in
2013. These events add around 7K of memory which was wasted for the last 12
years.

Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices. I think this takes the
record for the most number of patch series (30+) over the longest
period of time (2+ years) to get merged properly. Many props go to
Wesley Cheng for seeing this effort through, they took a major
out-of-tree hacked-up-monstrosity that was created by multiple
vendors for their specific devices, got it all merged into a
semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added for
the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues

Here is the big set of tty and serial driver changes for 6.16-rc1.
A little more churn than normal in this portion of the kernel for this
development cycle, Jiri and Nicholas were busy with cleanups and reviews
and fixes for the vt unicode handling logic which composed most of the
overall work in here.
Major changes are:
- vt unicode changes/reverts/changes from Nicholas. This should help
out a lot with screen readers and others that rely on vt console
support
- lock guard additions to the core tty/serial code to clean up lots of
error handling logic
- 8250 driver updates and fixes
- device tree conversions to yaml
- sh-sci driver updates
- other small cleanups and updates for serial drivers and tty core
