A64_LDRSW() takes three registers: Xt, Xn, Xm as arguments and it loads
and sign extends the value at address Xn + Xm into register Xt.
Currently, the offset is being directly used in place of the tmp
register which has the offset already loaded by the last emitted
instruction.
This will cause JIT failures. The easiest way to reproduce this is to
test the following code through test_bpf module:
{
"BPF_LDX_MEMSX | BPF_W",
.u.insns_int = {
BPF_LD_IMM64(R1, 0x00000000deadbeefULL),
BPF_LD_IMM64(R2, 0xffffffffdeadbeefULL),
BPF_STX_MEM(BPF_DW, R10, R1, -7),
BPF_LDX_MEMSX(BPF_W, R0, R10, -7),
BPF_JMP_REG(BPF_JNE, R0, R2, 1),
BPF_ALU64_IMM(BPF_MOV, R0, 0),
BPF_EXIT_INSN(),
},
INTERNAL,
{ },
{ { 0, 0 } },
.stack_depth = 7,
},
We need to use the offset as -7 to trigger this code path, there could
be other valid ways to trigger this from proper BPF programs as well.
This code is rejected by the JIT because -7 is passed to A64_LDRSW() but
it expects a valid register (0 - 31).

This is caused by GCC moving memcpy() after assignments in
bpf_jit_plt(), resulting in NULL pointers being written instead of
the return and the target addresses.
Looking at the GCC internals, the reordering is allowed because the
alias analysis thinks that the memcpy() destination and the assignments'
left-hand-sides are based on different objects: new_plt and
bpf_plt_ret/bpf_plt_target respectively, and therefore they cannot
alias.
This is in turn due to a violation of the C standard:
When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object
...
From the C's perspective, bpf_plt_ret and bpf_plt are distinct objects
and cannot be subtracted. In the practical terms, doing so confuses the
GCC's alias analysis.
The code was written this way in order to let the C side know a few
offsets defined in the assembly. While nice, this is by no means
necessary. Fix the noncompliance by hardcoding these offsets.

The selftests use
to tell LLVM about special pointers. For LLVM there is nothing "arena"
about them. They are simply pointers in a different address space.
Hence LLVM diff https://github.com/llvm/llvm-project/pull/85161 renamed:
. macro __BPF_FEATURE_ARENA_CAST -> __BPF_FEATURE_ADDR_SPACE_CAST
. global variables in __attribute__((address_space(N))) are now

Currently, the x86 JIT handling PROBE_MEM32 tagged accesses is not
equipped to handle atomic accesses into PTR_TO_ARENA, as no PROBE_MEM32
tagging is performed and no handling is enabled for them.
This will lead to unsafety as the offset into arena will dereferenced
directly without turning it into a base + offset access into the arena
region.
Since the changes to the x86 JIT will be fairly involved, for now,
temporarily disallow use of PTR_TO_ARENA as the destination operand for
atomics until support is added to the JIT backend.

Commit 870c7ad4a52b ("devlink: protect devlink->dev by the instance
lock") added devlink instance locking inside a loop that iterates over
all the registered devlink instances on the machine in the pre-doit
phase. This can lead to serialization of devlink commands over
different devlink instances.
For example: While the first devlink instance is executing firmware
flash, all commands to other devlink instances on the machine are
forced to wait until the first devlink finishes.
Therefore, in the pre-doit phase, take the devlink instance lock only
for the devlink instance the command is targeting. Devlink layer is
taking a reference on the devlink instance, ensuring the devlink->dev
pointer is valid. This reference taking was introduced by commit
a380687200e0 ("devlink: take device reference for devlink object").
Without this commit, it would not be safe to access devlink->dev
lockless.

syzkaller reported a warning of netns tracker [0] followed by KASAN
splat [1] and another ref tracker warning [1].
syzkaller could not find a repro, but in the log, the only suspicious
sequence was as follows:
18:26:22 executing program 1:
r0 = socket$inet6_mptcp(0xa, 0x1, 0x106)
...
connect$inet6(r0, &(0x7f0000000080)={0xa, 0x4001, 0x0, @loopback}, 0x1c) (async)
The notable thing here is 0x4001 in connect(), which is RDS_TCP_PORT.
So, the scenario would be:
1. unshare(CLONE_NEWNET) creates a per netns tcp listener in
rds_tcp_listen_init().
2. syz-executor connect()s to it and creates a reqsk.
3. syz-executor exit()s immediately.
4. netns is dismantled. [0]
5. reqsk timer is fired, and UAF happens while freeing reqsk. [1]
6. listener is freed after RCU grace period. [2]
Basically, reqsk assumes that the listener guarantees netns safety
until all reqsk timers are expired by holding the listener's refcount.
However, this was not the case for kernel sockets.
Commit 740ea3c4a0b2 ("tcp: Clean up kernel listener's reqsk in
inet_twsk_purge()") fixed this issue only for per-netns ehash.
Let's apply the same fix for the global ehash.

inet_twsk_purge() uses rcu to find TIME_WAIT and NEW_SYN_RECV
objects to purge.
These objects use SLAB_TYPESAFE_BY_RCU semantic and need special
care. We need to use refcount_inc_not_zero(&sk->sk_refcnt).
Reuse the existing correct logic I wrote for TIME_WAIT,
because both structures have common locations for
sk_state, sk_family, and netns pointer.
If after the refcount_inc_not_zero() the object fields longer match
the keys, use sock_gen_put(sk) to release the refcount.
Then we can call inet_twsk_deschedule_put() for TIME_WAIT,
inet_csk_reqsk_queue_drop_and_put() for NEW_SYN_RECV sockets,
with BH disabled.
Then we need to restart the loop because we had drop rcu_read_lock().

Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".

Pull hardening updates from Kees Cook:
"As is pretty normal for this tree, there are changes all over the
place, especially for small fixes, selftest improvements, and improved
macro usability.
Some header changes ended up landing via this tree as they depended on
the string header cleanups. Also, a notable set of changes is the work
for the reintroduction of the UBSAN signed integer overflow sanitizer
so that we can continue to make improvements on the compiler side to
make this sanitizer a more viable future security hardening option.

Pull btrfs updates from David Sterba:
"Mostly stabilization, refactoring and cleanup changes. There rest are
minor performance optimizations due to caching or lock contention
reduction and a few notable fixes.
Performance improvements:
- minor speedup in logging when repeatedly allocated structure is
preallocated only once, improves latency and decreases lock
contention
- minor throughput increase (+6%), reduced lock contention after
clearing delayed allocation bits, applies to several common
workload types
- skip full quota rescan if a new relation is added in the same
transaction
Fixes:
- zstd fix for inline compressed file in subpage mode, updated
version from the 6.8 time
- proper qgroup inheritance ioctl parameter validation
- more fiemap followup fixes after reduced locking done in 6.8:
- fix race when detecting delalloc ranges
Core changes:
- more debugging code:
- added assertions for a very rare crash in raid56 calculation
- tree-checker dumps page state to give more insights into
possible reference counting issues
- add checksum calculation offloading sysfs knob, for now enabled
under DEBUG only to determine a good heuristic for deciding the
offload or synchronous, depends on various factors (block group
profile, device speed) and is not as clear as initially thought
(checksum type)
- error handling improvements, added assertions
- more page to folio conversion (defrag, truncate), cached size and
shift
- preparation for more fine grained locking of sectors in subpage
mode
- cleanups and refactoring:
- include cleanups, forward declarations
- pointer-to-structure helpers
- redundant argument removals
- removed unused code
- slab cache updates, last use of SLAB_MEM_SPREAD removed"

zonefs: convert zonefs to use the new mount api
Just two small updates this time:
- A series I did to unify the definition of PAGE_SIZE through Kconfig,
intended to help with a vdso rework that needs the constant but
cannot include the normal kernel headers when building the compat
VDSO on arm64 and potentially others.
- a patch from Yan Zhao to remove the pfn_to_virt() definitions from
a couple of architectures after finding they were both incorrect
and entirely unused.

There is very little going on with new SoC support this time, all the
new chips are variations of others that we already support, and they
are all based on ARMv8 cores:
- Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are
networking SoCs designed to be used in wireless routers, similar
to the already supported MT7986A (Filogic 830).
- NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less.
These are used in many embedded and industrial applications.
- Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M)
are automotive SoCs.
- TI J722S is another automotive variant of its K3 family,
related to the AM62 series.
There are a total of 7 new arm32 machines and 45 arm64 ones, including
- Two Android phones based on the old Tegra30 chip
- Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and
a SoM development board
- A set-top box using Amlogic Meson G12A S905X2
- Eight embedded board using NXP i.MX6/8/9
- Three machines using Mediatek network router chips
- Ten Chromebooks, all based on Mediatek MT8186
- One development board based on Mediatek MT8395 (Genio 1200)
- Seven tablets and phones based on Qualcomm SoCs, most of them
from Samsung.
- A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2)
- Three variants of the "White Hawk" board for Renesas
automotive SoCs
- Ten Rockchips RK35xx based machines, including NAS, Tablet,
Game console and industrial form factors.
- Three evaluation boards for TI K3 based SoCs
The other changes are mainly the usual feature additions for existing hardware,
cleanups, and dtc compile time fixes. One notable change is the inclusion
of PowerVR SGX GPU nodes on TI SoCs.
