net: ftgmac100: fix potential NULL pointer access in ftgmac100_phy_disconnect
After the call to phy_disconnect() netdev->phydev is reset to NULL.
So fixed_phy_unregister() would be called with a NULL pointer as argument.
Therefore cache the phy_device before this call.

net/sched: mqprio: fix stack out-of-bounds write in tc entry parsing
TCA_MQPRIO_TC_ENTRY_INDEX is validated using
NLA_POLICY_MAX(NLA_U32, TC_QOPT_MAX_QUEUE), which allows the value
TC_QOPT_MAX_QUEUE (16). This leads to a 4-byte out-of-bounds stack
write in the fp[] array, which only has room for 16 elements (0–15).
Fix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1.

selftests: net: packetdrill: xfail all problems on slow machines
We keep seeing flakes on packetdrill on debug kernels, while non-debug kernels are stable, not a single flake in 200 runs. Time to give up, debug kernels appear to suffer from 10msec latency spikes and any timing-sensitive test is bound to flake.

ipa: fix compile-testing with qcom-mdt=m
There are multiple drivers that use the qualcomm mdt loader, but they
have conflicting ideas of how to deal with that dependency when compile-testing
for non-qualcomm targets:
IPA only enables the MDT loader when the kernel config includes ARCH_QCOM,
but the newly added ath12k support always enables it, which leads to a
link failure with the combination of IPA=y and ATH12K=m:
aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_firmware_load':
ipa_main.c:(.text.unlikely+0x134): undefined reference to `qcom_mdt_load
The ATH12K method seems more reliable here, so change IPA over to do the same
thing.

net: Add locking to protect skb->dev access in ip_output
In ip_output() skb->dev is updated from the skb_dst(skb)->dev this can become invalid when the interface is unregistered and freed, Introduced new skb_dst_dev_rcu() function to be used instead of skb_dst_dev() within rcu_locks in ip_output.This will ensure that all the skb's associated with the dev being deregistered will be transnmitted out first, before freeing the dev. Given that ip_output() is called within an rcu_read_lock() critical section or from a bottom-half context, it is safe to introduce an RCU read-side critical section within it. Multiple panic call stacks were observed when UL traffic was run in concurrency with device deregistration from different functions, pasting one sample for reference.

net/sched: taprio: enforce minimum value for picos_per_byte
Syzbot reported a WARNING in taprio_get_start_time().
When link speed is 470,589 or greater, q->picos_per_byte becomes too
small, causing length_to_duration(q, ETH_ZLEN) to return zero.
This zero value leads to validation failures in fill_sched_entry() and
parse_taprio_schedule(), allowing arbitrary values to be assigned to
entry->interval and cycle_time. As a result, sched->cycle can become zero.
Since SPEED_800000 is the largest defined speed in
include/uapi/linux/ethtool.h, this issue can occur in realistic scenarios.
To ensure length_to_duration() returns a non-zero value for minimum-sized
Ethernet frames (ETH_ZLEN = 60), picos_per_byte must be at least 17
(60 * 17 > PSEC_PER_NSEC which is 1000).
This patch enforces a minimum value of 17 for picos_per_byte when the
calculated value would be lower, and adds a warning message to inform
users that scheduling accuracy may be affected at very high link speeds.

selftests: net: Fix flaky neighbor garbage collection test
The purpose of the "Periodic garbage collection" test case is to make
sure that "extern_valid" neighbors are not flushed during periodic
garbage collection, unlike regular neighbor entries.
The test case is currently doing the following:
1. Changing the base reachable time to 10 seconds so that periodic
garbage collection will run every 5 seconds.
2. Changing the garbage collection stale time to 5 seconds so that
neighbors that have not been used in the last 5 seconds will be
considered for removal.
3. Waiting for the base reachable time change to take effect.
4. Adding an "extern_valid" neighbor, a non-"extern_valid" neighbor and
a bunch of other neighbors so that the threshold ("thresh1") will be
crossed and stale neighbors will be flushed during garbage
collection.
5. Waiting for 10 seconds to give garbage collection a chance to run.
6. Checking that the "extern_valid" neighbor was not flushed and that
the non-"extern_valid" neighbor was flushed.
The test sometimes fails in the netdev CI because the non-"extern_valid"
neighbor was not flushed. I am unable to reproduce this locally, but my
theory that since we do not know exactly when the periodic garbage
collection runs, it is possible for it to run at a time when the
non-"extern_valid" neighbor is still not considered stale.
Fix by moving the addition of the two neighbors before step 3 and by
reducing the garbage collection stale time to 1 second, to ensure that
both neighbors are considered stale when garbage collection runs.

netlink: avoid infinite retry looping in netlink_unicast()
netlink_attachskb() checks for the socket's read memory allocation
constraints. Firstly, it has:
rmem < READ_ONCE(sk->sk_rcvbuf)
to check if the just increased rmem value fits into the socket's receive
buffer. If not, it proceeds and tries to wait for the memory under:
rmem + skb->truesize > READ_ONCE(sk->sk_rcvbuf)
The checks don't cover the case when skb->truesize + sk->sk_rmem_alloc is
equal to sk->sk_rcvbuf. Thus the function neither successfully accepts
these conditions, nor manages to reschedule the task - and is called in
retry loop for indefinite time which is caught as:

net: phy: smsc: add proper reset flags for LAN8710A
According to the LAN8710A datasheet (Rev. B, section 3.8.5.1), a hardware reset is required after power-on, and the reference clock (REF_CLK) must be established before asserting reset.

net: ipa: add IPA v5.1 and v5.5 to ipa_version_string()
Handle the case for v5.1 and v5.5 instead of returning "0.0".
Also reword the comment below since I don't see any evidence of such a
check happening, and - since 5.5 has been missing - can happen.

phy: mscc: Fix parsing of unicast frames
According to the 1588 standard, it is possible to use both unicast and
multicast frames to send the PTP information. It was noticed that if the
frames were unicast they were not processed by the analyzer meaning that
they were not timestamped. Therefore fix this to match also these
unicast frames.

netpoll: prevent hanging NAPI when netcons gets enabled
Paolo spotted hangs in NIPA running driver tests against virtio.
The tests hang in virtnet_close() -> virtnet_napi_tx_disable().
The problem is only reproducible if running multiple of our tests
in sequence (I used TEST_PROGS="xdp.py ping.py netcons_basic.sh \
netpoll_basic.py stats.py"). Initial suspicion was that this is
a simple case of double-disable of NAPI, but instrumenting the
code reveals:
Deadlocked on NAPI ffff888007cd82c0 (virtnet_poll_tx):
state: 0x37, disabled: false, owner: 0, listed: false, weight: 64
The NAPI was not in fact disabled, owner is 0 (rather than -1),
so the NAPI "thinks" it's scheduled for CPU 0 but it's not listed
(!list_empty(&n->poll_list) => false). It seems odd that normal NAPI
processing would wedge itself like this.
Better suspicion is that netpoll gets enabled while NAPI is polling,
and also grabs the NAPI instance. This confuses napi_complete_done():
[netpoll] [normal NAPI]
napi_poll()
have = netpoll_poll_lock()
rcu_access_pointer(dev->npinfo)
return NULL # no netpoll
__napi_poll()
->poll(->weight)
poll_napi()
cmpxchg(->poll_owner, -1, cpu)
poll_one_napi()
set_bit(NAPI_STATE_NPSVC, ->state)
napi_complete_done()
if (NAPIF_STATE_NPSVC)
return false
# exit without clearing SCHED
This feels very unlikely, but perhaps virtio has some interactions
with the hypervisor in the NAPI ->poll that makes the race window
larger?
Best I could to to prove the theory was to add and trigger this
warning in napi_poll (just before netpoll_poll_unlock()):
WARN_ONCE(!have && rcu_access_pointer(n->dev->npinfo) &&
napi_is_scheduled(n) && list_empty(&n->poll_list),
"NAPI race with netpoll %px", n);
If this warning hits the next virtio_close() will hang.
This patch survived 30 test iterations without a hang (without it
the longest clean run was around 10). Credit for triggering this
goes to Breno's recent netconsole tests.

kcm: Fix splice support
Flags passed in for splice() syscall should not end up in skb_recv_datagram(). As SPLICE_F_NONBLOCK == MSG_PEEK, kernel gets confused: skb isn't unlinked from a receive queue, while strp_msg::offset and strp_msg::full_len are updated. Unbreak the logic a bit more by mapping both O_NONBLOCK and SPLICE_F_NONBLOCK to MSG_DONTWAIT. This way we align with man splice(2) in regard to errno EAGAIN: SPLICE_F_NONBLOCK was specified in flags or one of the file descriptors had been marked as nonblocking (O_NONBLOCK), and the operation would block.

Networking changes for 6.17.
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.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.

Summary
* Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective subsystems. Only 5
(out of the original 50) will remain in kernel/sysctl.c file; these handle
either sysctl or common arch variables.
By decentralizing sysctl registrations, subsystem maintainers regain control
over their sysctl interfaces, improving maintainability and reducing the
likelihood of merge conflicts.
* docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented in the
check-sysctl-docs script. This script can now be used to automatically
identify if documentation is missing.
* Testing
All these have been in linux-next since rc3, giving them a solid 3 to 4 weeks
worth of testing. Additionally, sysctl selftests and kunit were also run
locally on my x86_64

s390 updates for 6.17 merge window
- Standardize on the __ASSEMBLER__ macro that is provided by GCC and Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both uapi and non-uapi headers - Explicitly include <linux/export.h> in architecture and driver files which contain an EXPORT_SYMBOL() and remove the include from the files which do not contain the EXPORT_SYMBOL() - Use the full title of "z/Architecture Principles of Operation" manual and the name of a section where facility bits are listed - Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid unnecessary slowing down of the build and confusing external kABI tools that process symtypes data - Print additional unrecoverable machine check information to make the root cause analysis easier - Move cmpxchg_user_key() handling to uaccess library code, since the generated code is large anyway and there is no benefit if it is inlined - Fix a problem when cmpxchg_user_key() is executing a code with a non-default key: if a system is IPL-ed with "LOAD NORMAL", and the previous system used storage keys where the fetch-protection bit was set for some pages, and the cmpxchg_user_key() is located within such page, a protection exception happens - Either the external call or emergency signal order is used to send an IPI to a remote CPU.
