SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
reworks and support for variants of the existing SoC. While this remains
Arm centric for the most part, the branch now also contains updates to
risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants
(MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
soc ID, rpmh, rpm, spm and powerdomain drivers.
- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines
- A new SoC identification driver for the loongson-2 (loongarch)
platform
- memory controller updates for stm32, tegra, and renesas.
- a new DT binding to better describe LPDDR2/3/4/5 chips in
the memory controller subsystem
- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification
- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
TI, Mediatek and Marvell SoC drivers

arm64 updates for 6.2
ACPI:
* Enable FPDT support for boot-time profiling
* Fix CPU PMU probing to work better with PREEMPT_RT
* Update SMMUv3 MSI DeviceID parsing to latest IORT spec
* APMT support for probing Arm CoreSight PMU devices
CPU features:
* Advertise new SVE instructions (v2.1)
* Advertise range prefetch instruction
* Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
* Enable DIT (Data Independent Timing) when running in the kernel
* More conversion of system register fields over to the generated
header
CPU misfeatures:
* Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
* Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's
pointer authentication feature when it is supported (complete
with scary DWARF parser!)
Tracing and debug:
* Remove static ftrace in favour of, err, dynamic ftrace!
* Seperate 'struct ftrace_regs' from 'struct pt_regs' in core
ftrace and existing arch code
* Introduce and implement FTRACE_WITH_ARGS on arm64 to replace
the old FTRACE_WITH_REGS
* Extend 'crashkernel=' parameter with default value and fallback
to placement above 4G physical if initial (low) allocation
fails
SVE:
* Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
* Rework of undefined instruction handling to avoid serialisation
on global lock (this includes emulation of user accesses to the
ID registers)
Perf and PMU:
* Support for TLP filters in Hisilicon's PCIe PMU device
* Support for the DDR PMU present in Amlogic Meson G12 SoCs
* Support for the terribly-named "CoreSight PMU" architecture
from Arm (and Nvidia's implementation of said architecture)
Misc:
* Tighten up our boot protocol for systems with memory above
52 bits physical
* Const-ify static keys to satisty jump label asm constraints
* Trivial FFA driver cleanups in preparation for v1.1 support
* Export the kernel_neon_* APIs as GPL symbols
* Harden our instruction generation routines against
instrumentation
* A bunch of robustness improvements to our arch-specific selftests
* Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)

Merge tag 'slab-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLOB deprecation and SLUB_TINY
The SLOB allocator adds maintenance burden and stands in the way of
API improvements [1]. Deprecate it by renaming the config option (to
make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
SLUB should be used instead as SLAB will be the next on the removal
list.
Based on reports from a riscv k210 board with 8MB RAM, add a
CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
expense of scalability. This has resolved the k210 regression [2] so
in case there are no others (that wouldn't be resolvable by further
tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
Existing defconfigs with CONFIG_SLOB are converted to
CONFIG_SLUB_TINY.
- kmalloc() slub_debug redzone improvements
A series from Feng Tang that builds on the tracking or requested size
for kmalloc() allocations (for caches with debugging enabled) added
in 6.1, to make redzone checks consider the requested size and not
the rounded up one, in order to catch more subtle buffer overruns.
Includes new slub_kunit test.
- struct slab fields reordering to accomodate larger rcu_head
RCU folks would like to grow rcu_head with debugging options, which
breaks current struct slab layout's assumptions, so reorganize it to
make this possible.
- Miscellaneous improvements/fixes:
- __alloc_size checking compiler workaround (Kees Cook)
- Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)
- Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina)
- Correct SLUB's percpu allocation estimates (Baoquan He)
- Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov)
- Make tools/vm/slabinfo more user friendly when not run as root (Rong Tao)
- Dead code removal in SLUB (Hyeonggon Yoo)

Merge tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
this_cpu_inc() on strong load-store architectures.
- Introduce new console_list_lock to synchronize a manipulation of the
list of registered consoles and their flags.
This is a first step in removing the big-kernel-lock-like behavior of
console_lock(). This semaphore still serializes console->write()
calbacks against:
- each other. It primary prevents potential races between early
and proper console drivers using the same device.
- suspend()/resume() callbacks and init() operations in some
drivers.
- various other operations in the tty/vt and framebufer
susbsystems. It is likely that console_lock() serializes even
operations that are not directly conflicting with the
console->write() callbacks here. This is the most complicated
big-kernel-lock aspect of the console_lock() that will be hard
to untangle.
- Introduce new console_srcu lock that is used to safely iterate and
access the registered console drivers under SRCU read lock.
This is a prerequisite for introducing atomic console drivers and
console kthreads. It will reduce the complexity of serialization
against normal consoles and console_lock(). Also it should remove the
risk of deadlock during critical situations, like Oops or panic, when
only atomic consoles are registered.
- Check whether the console is registered instead of enabled on many
locations. It was a historical leftover.
- Cleanly force a preferred console in xenfb code instead of a dirty
hack.
- A lot of code and comment clean ups and improvements.

RCU pull request for v6.2
This pull request contains the following branches: doc.2022.10.20a: Documentation updates. This is the second in a series from an ongoing review of the RCU documentation. fixes.2022.10.21a: Miscellaneous fixes. lazy.2022.11.30a: Introduces a default-off Kconfig option that depends on RCU_NOCB_CPU that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument CPU lists, causes call_rcu() to introduce delays. These delays result in significant power savings on nearly idle Android and ChromeOS systems. These savings range from a few percent to more than ten percent. This series also includes several commits that change call_rcu() to a new call_rcu_hurry() function that avoids these delays in a few cases, for example, where timely wakeups are required. Several of these are outside of RCU and thus have acks and reviews from the relevant maintainers. srcunmisafe.2022.11.09a: Creates an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe() for architectures that support NMIs, but which do not provide NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required by the upcoming lockless printk() work by John Ogness et al. That printk() series depends on these commits, so if you pull the printk() series before this one, you will have already pulled in this branch, plus two more SRCU commits: |

memcg: fix possible use-after-free in memcg_write_event_control()
memcg_write_event_control() accesses the dentry->d_name of the specified control fd to route the write call. As a cgroup interface file can't be renamed, it's safe to access d_name as long as the specified file is a regular cgroup file. Also, as these cgroup interface files can't be removed before the directory, it's safe to access the parent too. Prior to |

mmap: fix do_brk_flags() modifying obviously incorrect VMAs
Add more sanity checks to the VMA that do_brk_flags() will expand. Ensure
the VMA matches basic merge requirements within the function before
calling can_vma_merge_after().
Drop the duplicate checks from vm_brk_flags() since they will be enforced
later.
The old code would expand file VMAs on brk(), which is functionally
wrong and also dangerous in terms of locking because the brk() path
isn't designed for file VMAs and therefore doesn't lock the file
mapping. Checking can_vma_merge_after() ensures that new anonymous
VMAs can't be merged into file VMAs.

mm/swap: fix SWP_PFN_BITS with CONFIG_PHYS_ADDR_T_64BIT on 32bit
We use "unsigned long" to store a PFN in the kernel and phys_addr_t to
store a physical address.
On a 64bit system, both are 64bit wide. However, on a 32bit system, the
latter might be 64bit wide. This is, for example, the case on x86 with
PAE: phys_addr_t and PTEs are 64bit wide, while "unsigned long" only spans
32bit.
The current definition of SWP_PFN_BITS without MAX_PHYSMEM_BITS misses
that case, and assumes that the maximum PFN is limited by an 32bit
phys_addr_t. This implies, that SWP_PFN_BITS will currently only be able
to cover 4 GiB - 1 on any 32bit system with 4k page size, which is wrong.
Let's rely on the number of bits in phys_addr_t instead, but make sure to
not exceed the maximum swap offset, to not make the BUILD_BUG_ON() in
is_pfn_swap_entry() unhappy. Note that swp_entry_t is effectively an
unsigned long and the maximum swap offset shares that value with the swap
type.
For example, on an 8 GiB x86 PAE system with a kernel config based on
Debian 11.5 (-> CONFIG_FLATMEM=y, CONFIG_X86_PAE=y), we will currently
fail removing migration entries (remove_migration_ptes()), because
mm/page_vma_mapped.c:check_pte() will fail to identify a PFN match as
swp_offset_pfn() wrongly masks off PFN bits. For example,
split_huge_page_to_list()->...->remap_page() will leave migration entries
in place and continue to unlock the page.
Later, when we stumble over these migration entries (e.g., via
/proc/self/pagemap), pfn_swap_entry_to_page() will BUG_ON() because these
migration entries shouldn't exist anymore and the page was unlocked.

tmpfs: fix data loss from failed fallocate
Fix tmpfs data loss when the fallocate system call is interrupted by a
signal, or fails for some other reason. The partial folio handling in
shmem_undo_range() forgot to consider this unfalloc case, and was liable
to erase or truncate out data which had already been committed earlier.
It turns out that none of the partial folio handling there is appropriate
for the unfalloc case, which just wants to proceed to removal of whole
folios: which find_get_entries() provides, even when partially covered.
Original patch by Rui Wang.

mm: do not BUG_ON missing brk mapping, because userspace can unmap it
The following program will trigger the BUG_ON that this patch removes,
because the user can munmap() mm->brk:
#include <sys/syscall.h>
#include <sys/mman.h>
#include <assert.h>
#include <unistd.h>
static void *brk_now(void)
{
return (void *)syscall(SYS_brk, 0);
}
static void brk_set(void *b)
{
assert(syscall(SYS_brk, b) != -1);
}
int main(int argc, char *argv[])
{
void *b = brk_now();
brk_set(b + 4096);
assert(munmap(b - 4096, 4096 * 2) == 0);
brk_set(b);
return 0;
}
Compile that with musl, since glibc actually uses brk(), and then
execute it, and it'll hit this splat:

are dropping it for now, and it will be revisited for 6.2 or 6.3

memcg: Fix possible use-after-free in memcg_write_event_control()
memcg_write_event_control() accesses the dentry->d_name of the specified control fd to route the write call. As a cgroup interface file can't be renamed, it's safe to access d_name as long as the specified file is a regular cgroup file. Also, as these cgroup interface files can't be removed before the directory, it's safe to access the parent too. Prior to |

net: dsa: sja1105: avoid out of bounds access in sja1105_init_l2_policing()
The SJA1105 family has 45 L2 policing table entries
(SJA1105_MAX_L2_POLICING_COUNT) and SJA1110 has 110
(SJA1110_MAX_L2_POLICING_COUNT). Keeping the table structure but
accounting for the difference in port count (5 in SJA1105 vs 10 in
SJA1110) does not fully explain the difference. Rather, the SJA1110 also
has L2 ingress policers for multicast traffic. If a packet is classified
as multicast, it will be processed by the policer index 99 + SRCPORT.
The sja1105_init_l2_policing() function initializes all L2 policers such
that they don't interfere with normal packet reception by default. To have
a common code between SJA1105 and SJA1110, the index of the multicast
policer for the port is calculated because it's an index that is out of
bounds for SJA1105 but in bounds for SJA1110, and a bounds check is
performed.
The code fails to do the proper thing when determining what to do with the
multicast policer of port 0 on SJA1105 (ds->num_ports = 5). The "mcast"
index will be equal to 45, which is also equal to
table->ops->max_entry_count (SJA1105_MAX_L2_POLICING_COUNT). So it passes
through the check. But at the same time, SJA1105 doesn't have multicast
policers. So the code programs the SHARINDX field of an out-of-bounds
element in the L2 Policing table of the static config.
The comparison between index 45 and 45 entries should have determined the
code to not access this policer index on SJA1105, since its memory wasn't
even allocated.
With enough bad luck, the out-of-bounds write could even overwrite other
valid kernel data, but in this case, the issue was detected using KASAN.
