ptrace: Cleanups for v5.18
This set of changes removes tracehook.h, moves modification of all of
the ptrace fields inside of siglock to remove races, adds a missing
permission check to ptrace.c
The removal of tracehook.h is quite significant as it has been a major
source of confusion in recent years. Much of that confusion was
around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
making the semantics clearer).
For people who don't know tracehook.h is a vestiage of an attempt to
implement uprobes like functionality that was never fully merged, and
was later superseeded by uprobes when uprobes was merged. For many
years now we have been removing what tracehook functionaly a little
bit at a time. To the point where now anything left in tracehook.h is
some weird strange thing that is difficult to understand.
Eric W. Biederman (15):
ptrace: Move ptrace_report_syscall into ptrace.h
ptrace/arm: Rename tracehook_report_syscall report_syscall
ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h
ptrace: Remove arch_syscall_{enter,exit}_tracehook
ptrace: Remove tracehook_signal_handler
task_work: Remove unnecessary include from posix_timers.h
task_work: Introduce task_work_pending
task_work: Call tracehook_notify_signal from get_signal on all architectures
task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
resume_user_mode: Move to resume_user_mode.h
tracehook: Remove tracehook.h
ptrace: Move setting/clearing ptrace_message into ptrace_stop
ptrace: Return the signal to continue with from ptrace_stop
Jann Horn (1):
ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE
Yang Li (1):
ptrace: Remove duplicated include in ptrace.c

USB/Thunderbolt patches for 5.18-rc1
Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
Nothing major in here, just lots of little improvements and cleanups and
new device support. Highlights are:
- list iterator fixups for when we walk past the end of the list
(a common problem that was cut/pasted in almost all USB gadget
drivers)
- xen USB driver "hardening" for malicious hosts
- xhci driver updates and fixes for more hardware types
- xhci debug cable fixes to make it actually work again
- usb gadget audio driver improvements
- usb gadget storage fixes to work with OS-X
- lots of other small usb gadget fixes and updates
- USB DWC3 driver improvements for more hardware types
- Lots of other small USB driver improvements
- DTS updates for some USB platforms
Note, the DTS updates will have a merge conflict in your tree. The
fixup should be simple, but if not, I can provide a merged tree if
needed.
All of these have been in linux-next for a while with no reported
issues.

Kbuild -std=gnu11 updates for v5.18
Linus pointed out the benefits of C99 some years ago, especially variable declarations in loops [1]. At that time, we were not ready for the migration due to old compilers. Recently, Jakob Koschel reported a bug in list_for_each_entry(), which leaks the invalid pointer out of the loop [2]. In the discussion, we agreed that the time had come. Now that GCC 5.1 is the minimum compiler version, there is nothing to prevent us from going to -std=gnu99, or even straight to -std=gnu11. Discussions for a better list iterator implementation are ongoing, but this patch set must land first.

kasan, arm64: don't tag executable vmalloc allocations
Besides asking vmalloc memory to be executable via the prot argument of __vmalloc_node_range() (see the previous patch), the kernel can skip that bit and instead mark memory as executable via set_memory_x(). Once tag-based KASAN modes start tagging vmalloc allocations, executing code from such allocations will lead to the PC register getting a tag, which is not tolerated by the kernel. Generic kernel code typically allocates memory via module_alloc() if it intends to mark memory as executable. (On arm64 module_alloc() uses __vmalloc_node_range() without setting the executable bit). Thus, reset pointer tags of pointers returned from module_alloc(). However, on arm64 there's an exception: the eBPF subsystem. Instead of using module_alloc(), it uses vmalloc() (via bpf_jit_alloc_exec()) to allocate its JIT region. Thus, reset pointer tags of pointers returned from bpf_jit_alloc_exec(). Resetting tags for these pointers results in untagged pointers being passed to set_memory_x(). This causes conflicts in arithmetic checks in change_memory_common(), as vm_struct->addr pointer returned by find_vm_area() is tagged. Reset pointer tag of find_vm_area(addr)->addr in change_memory_common().

kasan, vmalloc, arm64: mark vmalloc mappings as pgprot_tagged
HW_TAGS KASAN relies on ARM Memory Tagging Extension (MTE). With MTE, a memory region must be mapped as MT_NORMAL_TAGGED to allow setting memory tags via MTE-specific instructions. Add proper protection bits to vmalloc() allocations. These allocations are always backed by page_alloc pages, so the tags will actually be getting set on the corresponding physical memory.

kasan, arm64: reset pointer tags of vmapped stacks
Once tag-based KASAN modes start tagging vmalloc() allocations, kernel stacks start getting tagged if CONFIG_VMAP_STACK is enabled. Reset the tag of kernel stack pointers after allocation in arch_alloc_vmap_stack(). For SW_TAGS KASAN, when CONFIG_KASAN_STACK is enabled, the instrumentation can't handle the SP register being tagged. For HW_TAGS KASAN, there's no instrumentation-related issues. However, the impact of having a tagged SP register needs to be properly evaluated, so keep it non-tagged for now. Note, that the memory for the stack allocation still gets tagged to catch vmalloc-into-stack out-of-bounds accesses.

kasan, x86, arm64, s390: rename functions for modules shadow
Rename kasan_free_shadow to kasan_free_module_shadow and kasan_module_alloc to kasan_alloc_module_shadow. These functions are used to allocate/free shadow memory for kernel modules when KASAN_VMALLOC is not enabled. The new names better reflect their purpose. Also reword the comment next to their declaration to improve clarity.

Networking changes for 5.18.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

- Zap roots in two passes, avoiding RCU read-side critical sections
that last too long for very large guests backed by 4 KiB SPTEs.
- Zap invalid and defunct roots asynchronously via concurrency-managed
work queue.
- Allowing yielding when zapping TDP MMU roots in response to the root's
last reference being put.
- Batch more TLB flushes with an RCU trick. Whoever frees the paging
structure now holds RCU as a proxy for all vCPUs running in the guest,
i.e. to prolongs the grace period on their behalf. It then kicks the
the vCPUs out of guest mode before doing rcu_read_unlock().
Generic:

ARM: DT updates for 5.18
After a somewhat quiet 5.17 release, the size of the DT changes
is a bit larger again. There are nine new SoC that get added,
all of them related to existing platforms:
- Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G tablet
- Microchip Lan966 networking SoC and it evaluation board
- Qualcomm Snapdragon 625/632 midrange phone SoCs, with the
LG Nexus 5X and Fairphone FP3 phones
- Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs,
along with their evaluation boards
- Samsung Exynos 850 phone SoC and reference board
- Samsung Exynos7885 with the Samsung Galaxy A8 (2018) phone
- Tesla FSD (Fully Self-Driving), an automotive SoC losely derived
from the Samsung Exynos family.

Support for additional functionality in existing dts files is added all
over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
The new machines are really too many to list, but I'll do it anyway:
Allwinner:
- A20-Marsboard development board
Amlogic
- Amediatek X96-AIR (Amlogic S905X3)
- CYX A95XF3-AIR (Amlogic S905X3)
- Haochuangy H96-Max (Amlogic S905X3)
- Amlogic AQ222 (Amlogic S4)
- OSMC Vero 4K+ (Amlogic S905D)
Arm Juno
- Separate DT depending on SCMI firmware version
Aspeed:
- Quanta S6Q BMC (AST2600)
- ASRock ROMED8HM3 (AST2500)
Broadcom:
- Raspberry Pi Zero 2 W
Marvell MVEBU/Armada:
- Ctera C200 V1 NAS (kirkwood)
- Ctera C200 V2 NAS (armada-370)
Mstar
- DongShanPiOne, a low-end embedded board
- Miyoo Mini handheld game console
NXP i.MX:
- Numerous i.MX8M Mini based boards in even more variations, but
none based on other SoCs this time:
Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
Gateworks GW7903
Qualcomm:
- Google Herobrine R1 Chromebook platform (Snapdragon 7c Gen 3)
- SHIFT6mq phone (Snapdragon 845)
- Samsung Galaxy Book2 (Snapdragon 850)
- Snapdragon 8 Gen 1 Hardware Development Kit
TI OMAP:

ARM: defconfig updates for 5.18
Various updates for the 32-bit and 64-bit defconfig files, mostly to enable additional hardware drivers for more machines, specifically for the Allwinner F1C100, Altera SoCFPGA, Broadcom, Microchip, Qualcomm, Airoha, Tegra, Renesas, and i.NX. The multi_v5_defconfig for older ARMv5 configs gets a rework for Andre Przywara to cleans up the multi_v5_defconfig for some cruft that has accumulated and drivers that got disabled unintentionally, while Anders Roxell makes it more useful for running under Qemu. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmI7TfIACgkQmmx57+YA GNl9zw/+P4ookmNEJ8KRh0qxaI1ER64Vz1XuyzDVa5MwCg7td6Xc8bWTPSK7E7Rd EUrAYmcYBHPLm1iKtGwvQW7Y5HXyI8boQC/aqNeq3FvvRFQ5XdIqC4pMW2V0VdPE PTrqbjI03W3W4PvruBHUw9G9+DgTcO8T+smvb/3YE93hrbU4sZA3KkDYu8vSczk5 AX099vu3Gw9KtDuB/qE4ED1i0R0SA9S2qb1yYT3QSgHQ/p4ok7I6kauIASmBG5m9 LQ98cTzOIbvUo1PUpCmxS0Q+ABT0k2g6TqUZK5bU/3pSNpUWhKWKJZdICVTwO9P+ 2dSk4GhGW3VQna88ikmId+1qwaRkVDy7ldWeX2ciNZqlQONbSqaLab6Bw+HaNmDu oew1NHrjOXoiJFZ7si5kwReQOuc4NDKm5CWH5iRagnQxA1bmzxlKKDAiEejuAyoY xG8g+WcI00BVi49yoYnzxqyBdMaFAuO1IJ//UjpcO6n6KzcsZoo3lewO6Y0rO1OJ U43TDPvCYH/PS0dIsHx7x1DmXE31uKYI9mnhgBQmtYfaalqu3alZjZfTvWc9oW7i kL5dye44+oSjFptJSadIZu/mJbezDogE8+DlCQeAiUe93vYEqRKhLoE4rO8Kt+qx vAhWINk19m67ok2ctwF6vvOT3Cco3BhKxjY6MjD59nLVOpnrUcA= =/9iL -----END PGP SIGNATURE----- Merge tag 'arm-defconfig-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM defconfig updates from Arnd Bergmann: "Various updates for the 32-bit and 64-bit defconfig files, mostly to enable additional hardware drivers for more machines, specifically for the Allwinner F1C100, Altera SoCFPGA, Broadcom, Microchip, Qualcomm, Airoha, Tegra, Renesas, and i.NX.

asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

drivers/base/node: consolidate node device subsystem initialization in node_dev_init()
... and call node_dev_init() after memory_dev_init() from driver_init(), so before any of the existing arch/subsys calls. All online nodes should be known at that point: early during boot, arch code determines node and zone ranges and sets the relevant nodes online; usually this happens in setup_arch(). This is in line with memory_dev_init(), which initializes the memory device subsystem and creates all memory block devices. Similar to memory_dev_init(), panic() if anything goes wrong, we don't want to continue with such basic initialization errors. The important part is that node_dev_init() gets called after memory_dev_init() and after cpu_dev_init(), but before any of the relevant archs call register_cpu() to register the new cpu device under the node device. The latter should be the case for the current users of topology_init().

mm: merge pte_mkhuge() call into arch_make_huge_pte()
Each call into pte_mkhuge() is invariably followed by arch_make_huge_pte(). Instead arch_make_huge_pte() can accommodate pte_mkhuge() at the beginning. This updates generic fallback stub for arch_make_huge_pte() and available platforms definitions. This makes huge pte creation much cleaner and easier to follow.

"These are mostly fixes and cleanups all over the code and a new piece

Functionality-wise, the intel_idle driver will support Sapphire Rapids
Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the firmware,
cpupower utility will support the AMD P-state driver added in the
previous cycle, and there is a new tracer utility for that driver.

Pull ACPI updates from Rafael Wysocki:
"From the new functionality perspective, the most significant items
here are the new driver for the 'ARM Generic Diagnostic Dump and
Reset' device, the extension of fine grain fan control in the ACPI fan
driver, and the change making it possible to use CPPC information to
obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.
Specifics:

parport_pc: Also enable driver for PCI systems
Nowadays PC-style parallel ports come in the form of PCI and PCIe option cards and there are some combined parallel/serial option cards as well that we handle in the parport subsystem. There is nothing in particular that would prevent them from being used in any system equipped with PCI or PCIe connectivity, except that we do not permit the PARPORT_PC config option to be selected for platforms for which ARCH_MIGHT_HAVE_PC_PARPORT has not been set for. The only PCI platforms that actually can't make use of PC-style parallel port hardware are those newer PCIe systems that have no support for I/O cycles in the host bridge, required by such parallel ports. Notably, this includes the s390 arch, which has port I/O accessors that cause compilation warnings (promoted to errors with `-Werror'), and there are other cases such as the POWER9 PHB4 device, though this one has variable port I/O accessors that depend on the particular system. Also it is not clear whether the serial port side of devices enabled by PARPORT_SERIAL uses port I/O or MMIO. Finally Super I/O solutions are always either ISA or platform devices. Make the PARPORT_PC option selectable also for PCI systems then, except for the s390 arch, however limit the availability of PARPORT_PC_SUPERIO to platforms that enable ARCH_MIGHT_HAVE_PC_PARPORT. Update platforms accordingly for the required <asm/parport.h> header. Acked-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Signed-off-by: Maciej W.

arm64: dts: mt2712: update ethernet device node
Since there are some changes in ethernet driver:
update ethernet device node in dts to accommodate to it.
1. stmmac_probe_config_dt() in stmmac_platform.c will initialize specified
parameters according to compatible string "snps,dwmac-4.20a", then,
dwmac-mediatek.c can skip the initialization if add compatible string
"snps,dwmac-4.20a" in eth device node.
2. commit
