1d9f1b5e43 Here are the accumulated fixes for 7.1-rc1 and a single structural worth of
mentioning separately: Rafael's commit converting tpm_crb from ACPI driver
 to a platform driver. Starting from this release cycle, the branch with TPM
 changes mirrored to next is 'for-next-tpm', and patches for keys have their
 own separate 'for-next-keys' branch.

b2680ba4a2 spi: Fixes for v7.1
This is quite a big set of fixes, almost all from Johan Hovold who is on
 an ongoing quest to clean up issues with probe and removal handling in
 drivers.  There isn't anything too concerning here especially with the
 deregistration stuff which will very rarely get run in production
 systems since this is all platform devices in the SoC on embedded
 hardware, but it's all real issues which should be fixed.  There's more
 in flight here.
 
 We also have a few other minor fixes, one from Felix Gu along the same
 lines as Johan's work and a couple of documentation things.

64edfa6506 Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden
 to core networking developers. syzbot loves to find bugs
 in BKL-era code, and noobs try to fix them.
 
 If we want to have a fighting chance of surviving the LLM-pocalypse
 this code needs to find a dedicated owner or get deleted.
 We've talked about these deletions multiple times in the past
 and every time someone wanted the code to stay. It is never
 very clear to me how many of those people actually use the code
 vs are just nostalgic to see it go. Amateur radio did have
 occasional users (or so I think) but most users switched
 to user space implementations since its all super slow stuff.
 Nobody stepped up to maintain the kernel code.
 
 We were lucky enough to find someone who wants to help with NFC
 so we're giving that a chance. Let's try to put the rest of
 this code behind us.

e728258deb Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
 weeks before the merge window. Lots of AI-aided bug discovery.
 A newer big source is Sashiko/Gemini (Roman Gushchin's system),
 which points out issues in existing code during patch review
 (maybe 25% of fixes here likely originating from Sashiko).
 Nice thing is these are often fixed by the respective maintainers,
 not drive-bys.
 
 Current release - new code bugs:
 
  - kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
 
 Previous releases - regressions:
 
  - add async ndo_set_rx_mode and switch drivers which we promised
    to be called under the per-netdev mutex to it
 
  - dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops
 
  - hv_sock: report EOF instead of -EIO for FIN
 
  - vsock/virtio: fix MSG_PEEK calculation on bytes to copy
 
 Previous releases - always broken:
 
  - ipv6: fix possible UAF in icmpv6_rcv()
 
  - icmp: validate reply type before using icmp_pointers

eventpoll: refresh eventpoll_release() fast-path comment
The old comment justified the lockless READ_ONCE(file->f_ep) check
with "False positives simply cannot happen because the file is on
the way to be removed and nobody ( but eventpoll ) has still a
reference to this file." That reasoning was the root of the UAF
fixed in "eventpoll: fix ep_remove struct eventpoll / struct file
UAF": __ep_remove() could clear f_ep while another close raced
past the fast path and freed the watched eventpoll / recycled the
struct file slot.

With ep_remove() now pinning @file via epi_fget() across the f_ep
clear and hlist_del_rcu(), the invariant is re-established for the
right reason: anyone who might clear f_ep holds @file alive for
the duration, so a NULL observation really does mean no
concurrent eventpoll path has work left on this file. Refresh the
comment accordingly so the next reader doesn't inherit the broken
model.

0422e7a488 rxrpc: Fix re-decryption of RESPONSE packets
If a RESPONSE packet gets a temporary failure during processing, it may end
up in a partially decrypted state - and then get requeued for a retry.

Fix this by just discarding the packet; we will send another CHALLENGE
packet and thereby elicit a further response.  Similarly, discard an
incoming CHALLENGE packet if we get an error whilst generating a RESPONSE;
the server will send another CHALLENGE.

1f2740150f rxrpc: Fix potential UAF after skb_unshare() failure
If skb_unshare() fails to unshare a packet due to allocation failure in
rxrpc_input_packet(), the skb pointer in the parent (rxrpc_io_thread())
will be NULL'd out.  This will likely cause the call to
trace_rxrpc_rx_done() to oops.

Fix this by moving the unsharing down to where rxrpc_input_call_event()
calls rxrpc_input_call_packet().  There are a number of places prior to
that where we ignore DATA packets for a variety of reasons (such as the
call already being complete) for which an unshare is then avoided.

And with that, rxrpc_input_packet() doesn't need to take a pointer to the
pointer to the packet, so change that to just a pointer.

6deb535950 net: remove unused ATM protocols and legacy ATM device drivers
Remove the ATM protocol modules and PCI/SBUS ATM device drivers
that are no longer in active use.

The ATM core protocol stack, PPPoATM, BR2684, and USB DSL modem
drivers (drivers/usb/atm/) are retained in-tree to maintain PPP
over ATM (PPPoA) and PPPoE-over-BR2684 support for DSL connections.
The Solos ADSL2+ PCI driver is also retained.

Removed ATM protocol modules:
 - net/atm/clip.c - Classical IP over ATM (RFC 2225)
 - net/atm/lec.c - LAN Emulation Client (LANE)
 - net/atm/mpc.c, mpoa_caches.c, mpoa_proc.c - Multi-Protocol Over ATM

Removed PCI/SBUS ATM device drivers (drivers/atm/):
 - adummy, atmtcp - software/testing ATM devices
 - eni - Efficient Networks ENI155P (OC-3, ~1995)
 - fore200e - FORE Systems 200E PCI/SBUS (OC-3, ~1999)
 - he - ForeRunner HE (OC-3/OC-12, ~2000)
 - idt77105 - IDT 77105 25 Mbps ATM PHY
 - idt77252 - IDT 77252 NICStAR II (OC-3, ~2000)
 - iphase - Interphase ATM PCI (OC-3/DS3/E3)
 - lanai - Efficient Networks Speedstream 3010
 - nicstar - IDT 77201 NICStAR (155/25 Mbps, ~1999)
 - suni - PMC S/UNI SONET PHY library

Also clean up references in:
 - net/bridge/ - remove ATM LANE hook (br_fdb_test_addr_hook,
   br_fdb_test_addr)
 - net/core/dev.c - remove br_fdb_test_addr_hook export
 - defconfig files - remove ATM driver config options

The removed code is moved to an out-of-tree module package (mod-orphan).

dd8d4bc28a net: remove ax25 and amateur radio (hamradio) subsystem
Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation
and all associated hamradio device drivers from the kernel tree.
This set of protocols has long been a huge bug/syzbot magnet,
and since nobody stepped up to help us deal with the influx
of the AI-generated bug reports we need to move it out of tree
to protect our sanity.

The code is moved to an out-of-tree repo:
https://github.com/linux-netdev/mod-orphan
if it's cleaned up and reworked there we can accept it back.

Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP,
AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN)
so that the conditional integration code in arp.c and tun.c continues
to compile and work when the out-of-tree modules are loaded.

4f10f1dfb2 net: remove ISDN subsystem and Bluetooth CMTP
Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol
from the kernel tree.

ISDN is a pretty old technology and it's unclear whether anyone still
uses it. I went over the last few years of git history and all the
commits are either tree-wide conversions or syzbot/static analyzer
fixes.

When we discussed removal in the past IIRC there were some concerns
about ISDN still being used in parts of Germany. Unfortunately, the
code base is quite old, none of the current maintainers are familiar
with it and AI tools will have a field day finding bugs here.

Delete this code and preserve it in an out-of-tree repository
for any remaining users:
https://github.com/linux-netdev/mod-orphan

UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class
are preserved for ABI stability, but the rest of uAPI is removed.

6d5431555d caif: remove CAIF NETWORK LAYER
Remove CAIF (Communication CPU to Application CPU Interface), the
ST-Ericsson modem protocol. The subsystem has been orphaned since 2013.
The last meaningful changes from the maintainers were in March 2013:
  a8c7687bf2 ("caif_virtio: Check that vringh_config is not null")
  b2273be8d2 ("caif_virtio: Use vringh_notify_enable correctly")
  0d2e1a2926 ("caif_virtio: Introduce caif over virtio")

Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.

If anyone is using this code please yell!

In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a8).

We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.

UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.

fc69decc81 8021q: use RCU for egress QoS mappings
The TX fast path and reporting paths walk egress QoS mappings without
RTNL. Convert the mapping lists to RCU-protected pointers, use RCU
reader annotations in readers, and defer freeing mapping nodes with an
embedded rcu_head.

This prepares the egress QoS mapping code for safe removal of mapping
nodes in a follow-up change while preserving the current behavior.

pie_dump_stats() only runs with RTNL held,
reading fields that can be changed in qdisc fast path.

Add READ_ONCE()/WRITE_ONCE() annotations.

Alternative would be to acquire the qdisc spinlock, but our long-term
goal is to make qdisc dump operations lockless as much as we can.

tc_pie_xstats fields don't need to be latched atomically,
otherwise this bug would have been caught earlier.

3bfcf39608 net: validate skb->napi_id in RX tracepoints
Since commit 2bd82484bb ("xps: fix xps for stacked devices"),
skb->napi_id shares storage with sender_cpu. RX tracepoints using
net_dev_rx_verbose_template read skb->napi_id directly and can therefore
report sender_cpu values as if they were NAPI IDs.

For example, on the loopback path this can report 1 as napi_id, where 1
comes from raw_smp_processor_id() + 1 in the XPS path:

  # bpftrace -e 'tracepoint:net:netif_rx_entry{ print(args->napi_id); }'
  # taskset -c 0 ping -c 1 ::1

Report only valid NAPI IDs in these tracepoints and use 0 otherwise.

5d3869a41f NFS: fix writeback in presence of errors
After running xfstest generic/751, in certain conditions, can have
a writeback IO stuck while experiencing one of the two patterns.

Pattern#1: writeback IO experiences ENOSPC on an offset smaller
than the filesize. Example,
write offset=0 len=4096 how=unstable OK
write offset=8192 len=4096 how=unstable OK
write offset=12288 len=4096 how=unstable ENOSPC
write offset=4096 len=4096 how=unstable ENOSPC
client sends a commit and receives a verifier which is different
from the last successful write. It marks pages dirty and writeback
retries. But it again send writes unstable and gets into the same
pattern, running into the ENOSPC error and sending a commit because
writes were sent at unstable.

Pattern#2: an unstable write followed by a short write and ENOSPC.
write offset=0 len=4096 how=unstable OK
write offset=4096 len=4096 how=unstable returns OK but count=100
write offset=4197 len=3996 how=stable returns ENOSPC
client send a commit and receives a verifier different from
the last unstable write. The same behaviour is retried in a loop.

Instead, this patch proposes to identify those conditions and mark
requests to be done synchronously instead. Previous solution tried
to mark it in the nfs_page, however that's not persistent thus
instead mark it in the nfs_open_context.

Furthermore, the same problem occurs during localio code path so
recognize that IO needs to be done sync in that case as well.

5170a82e89 x86/hyperv: Skip LP/VP creation on kexec
After a kexec the logical processors and virtual processors already
exist in the hypervisor because they were created by the previous
kernel. Attempting to add them again causes either a BUG_ON or
corrupted VP state leading to MCEs in the new kernel.

Add hv_lp_exists() to probe whether an LP is already present by
calling HVCALL_GET_LOGICAL_PROCESSOR_RUN_TIME. When it succeeds the
LP exists and we skip the add-LP and create-VP loops entirely.

Also add hv_call_notify_all_processors_started() which informs the
hypervisor that all processors are online. This is required after
adding LPs (fresh boot) and is a no-op on kexec since we skip that
path.

256e5254ef kgdb: update outdated references to kgdb_wait()
The function kgdb_wait() was folded into the static function
kgdb_cpu_enter() by commit 62fae31219 ("kgdb: eliminate
kgdb_wait(), all cpus enter the same way").  Update the four stale
references accordingly:

 - include/linux/kgdb.h and arch/x86/kernel/kgdb.c: the
   kgdb_roundup_cpus() kdoc describes what other CPUs are rounded up
   to call.  Because kgdb_cpu_enter() is static, the correct public
   entry point is kgdb_handle_exception(); also fix a pre-existing
   grammar error ("get them be" -> "get them into") and reflow the
   text.

 - kernel/debug/debug_core.c: replace with the generic description
   "the debug trap handler", since the actual entry path is
   architecture-specific.

 - kernel/debug/gdbstub.c: kgdb_cpu_enter() is correct here (it
   describes internal state, not a call target); add the missing
   parentheses.

4ee64205ff We've finally gotten rid of the struct clk_ops::round_rate() code after months
of effort from Brian Masney. Now the only option is to use determine_rate(),
 which is good because that takes a struct argument instead of just a couple
 unsigned longs, allowing us to easily modify the way we determine and set rates
 in the clk tree.
 
 Beyond that core framework change we've got the typical pile of new SoC clk
 driver additions, fixes for clk data and/or adding missing clks because the
 consumer driver using those clks wasn't ready, etc. The usual suspects are all
 here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
 making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
 driver side of this looks pretty normal.

292a2bcd17 Fixing livelocks in shrink_dcache_tree()
If shrink_dcache_tree() finds a dentry in the middle of being killed
 by another thread, it has to wait until the victim finishes dying,
 gets detached from the tree and ceases to pin its parent.
 
 The way we used to deal with that amounted to busy-wait; unfortunately,
 it's not just inefficient but can lead to reliably reproducible hard
 livelocks.
 
 Solved by having shrink_dentry_tree() attach a completion to such dentry,
 with dentry_unlist() calling complete() on all objects attached to it.
 With a bit of care it can be done without growing struct dentry or adding
 overhead in normal case.

a4c8332781 net: cache snapshot entries for ndo_set_rx_mode_async
Add a per-device netdev_hw_addr_list cache (rx_mode_addr_cache) that
allows __hw_addr_list_snapshot() and __hw_addr_list_reconcile() to
reuse previously allocated entries instead of hitting GFP_ATOMIC on
every snapshot cycle.

snapshot pops entries from the cache when available, falling back to
__hw_addr_create(). reconcile splices both snapshot lists back into
the cache via __hw_addr_splice(). The cache is flushed in
free_netdev().

3554b4345d net: introduce ndo_set_rx_mode_async and netdev_rx_mode_work
Add ndo_set_rx_mode_async callback that drivers can implement instead
of the legacy ndo_set_rx_mode. The legacy callback runs under the
netif_addr_lock spinlock with BHs disabled, preventing drivers from
sleeping. The async variant runs from a work queue with rtnl_lock and
netdev_lock_ops held, in fully sleepable context.

When __dev_set_rx_mode() sees ndo_set_rx_mode_async, it schedules
netdev_rx_mode_work instead of calling the driver inline. The work
function takes two snapshots of each address list (uc/mc) under
the addr_lock, then drops the lock and calls the driver with the
work copies. After the driver returns, it reconciles the snapshots
back to the real lists under the lock.

Add netif_rx_mode_sync() to opportunistically execute the pending
workqueue update inline, so that rx mode changes are committed
before returning to userspace:
  - dev_change_flags (SIOCSIFFLAGS / RTM_NEWLINK)
  - dev_set_promiscuity
  - dev_set_allmulti
  - dev_ifsioc SIOCADDMULTI / SIOCDELMULTI
  - do_setlink (RTM_SETLINK)

Note that some deep hierarchies still do skip the lower updates via:
  - dev_uc_sync
  - dev_mc_sync

If we do end up hitting user-visible issues, we can add more calls to
netif_rx_mode_sync in specific places. But hopefully we should not,
the actual user-visible lists are still synced, it's that just HW state
that might be lagging.
