Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly
once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup
- Support inspecting ref_tracker state via DebugFS
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links
- Allow providing upcall pid for the 'execute' command in openvswitch
- Remove DCCP support from Netfilter's conntrack

- Prevent use of deprecated iptables code on PREEMPT_RT
Driver API:
- Support RSS and hashing configuration over ethtool Netlink

Pull staging updates from Greg KH:
"Here is the "big" set of staging driver changes for 6.17-rc1. That's
in quotes as it really isn't all that big of a set of changes this
development cycle at all.
Major things that stand out are:
- gpib cleanups and tweaks with the majority of the big issues now
taken care of. Odds are it will move out of staging/ in the next
merge window if all goes well.
- more constant cleanups and layer removals from the rtl8723bs
driver. It's amazing how many layers deep they really are, all
cleanups here are great to see
- axis-fifo sysfs api removed and debugfs api added. The sysfs api
didn't work at all so obviously no one was using it. Add the same
information into debugfs as that's the proper place for it, and
make it actually work.
- Remaining changes is lots of small checkpatch cleanups, most of
which seem to have come from a Debconf session where people were
encouraged to submit their first kernel patch, a nice thing to see
happen again.
All of these have been in linux-next with no reported issues"

When gmin_get_config_var() calls efi.get_variable() and the EFI variable
is larger than the expected buffer size, two behaviors combine to create
a stack buffer overflow:
1. gmin_get_config_var() does not return the proper error code when
efi.get_variable() fails. It returns the stale 'ret' value from
earlier operations instead of indicating the EFI failure.
2. When efi.get_variable() returns EFI_BUFFER_TOO_SMALL, it updates
*out_len to the required buffer size but writes no data to the output
buffer. However, due to bug #1, gmin_get_var_int() believes the call
succeeded.
The caller gmin_get_var_int() then performs:
- Allocates val[CFG_VAR_NAME_MAX + 1] (65 bytes) on stack
- Calls gmin_get_config_var(dev, is_gmin, var, val, &len) with len=64
- If EFI variable is >64 bytes, efi.get_variable() sets len=required_size
- Due to bug #1, thinks call succeeded with len=required_size
- Executes val[len] = 0, writing past end of 65-byte stack buffer
This creates a stack buffer overflow when EFI variables are larger than
64 bytes. Since EFI variables can be controlled by firmware or system
configuration, this could potentially be exploited for code execution.
Fix the bug by returning proper error codes from gmin_get_config_var()
based on EFI status instead of stale 'ret' value.
The gmin_get_var_int() function is called during device initialization
for camera sensor configuration on Intel Bay Trail and Cherry Trail
platforms using the atomisp camera stack.

The macro SET_BITS_TO_LE_2BYTE ends with a semicolon inside its definition,
which can lead to an extra semicolon when used, resulting in inconsistent

This patch removes the redundant semicolon to comply with kernel macro

For debugging purposes, add a simple, read-only debugfs interface to dump
the following fifo registers:
ISR - Interrupt Status Register
IER - Interrupt Enable Register
TDFV - Transmit Data FIFO Vacancy
RDFO - Receive Data FIFO Occupancy

The same abort is triggered if a read is attempted on RDFD register when
the fifo is empty.
Therefore, remove the sysfs interface and only let read()/write() modify
the fifo registers. For debugging purposes, a simple read-only debugfs
interface is added in the next patch.

gbphy_dev_match_id() should be taking a const pointer, as the pointer
passed to it from the container_of() call was const to start with (it
was accidentally cast away with the call.) Fix this all up by correctly

The commit 3e5def4249b9 ("staging: vchiq_arm: Improve initial VCHIQ connect")
based on the assumption that in good case the VCHIQ connect always happen and
therefore the keep-alive thread is guaranteed to be woken up. This is wrong,
because in certain configurations there are no VCHIQ users and so the VCHIQ
connect never happen. So revert it.
