arm64 fixes for 6.13-rc2:
- MTE/hugetlbfs:
- Set VM_MTE_ALLOWED in the arch code and remove it from the core code
for hugetlbfs mappings
- Fix copy_highpage() warning when the source is a huge page but not
MTE tagged, taking the wrong small page path
- drivers/virt/coco:
- Add the pKVM and Arm CCA drivers under the arm64 maintainership
- Fix the pkvm driver to fall back to ioremap() (and warn) if the
MMIO_GUARD hypercall fails
- Keep the Arm CCA driver default 'n' rather than 'm'
- A series of fixes for the arm64 ptrace() implementation, potentially
leading to the kernel consuming uninitialised stack variables when
PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and ZONE_DMA
is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a call
to page_to_phys() (from patch_map()) which checks pfn_valid() before
vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI ops
when the kernel assumes 8-bit ASIDs but running under a hypervisor on
a system that implements 16-bit ASIDs (found running Linux under
Parallels on Apple M4)
- ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it is
using the same SMMU PMCG as HIP09 and suffers from the same errata
- Add GCS to cpucap_is_possible(), missed in the recent merge

Merge branch 'fixes-for-lpm-trie'
Hou Tao says: ==================== This patch set fixes several issues for LPM trie. These issues were found during adding new test cases or were reported by syzbot. The patch set is structured as follows: Patch #1~#2 are clean-ups for lpm_trie_update_elem(). Patch #3 handles BPF_EXIST and BPF_NOEXIST correctly for LPM trie. Patch #4 fixes the accounting of n_entries when doing in-place update. Patch #5 fixes the exact match condition in trie_get_next_key() and it may skip keys when the passed key is not found in the map. Patch #6~#7 switch from kmalloc() to bpf memory allocator for LPM trie to fix several lock order warnings reported by syzbot. It also enables raw_spinlock_t for LPM trie again. After these changes, the LPM trie will be closer to being usable in any context (though the reentrance check of trie->lock is still missing, but it is on my todo list). Patch #8: move test_lpm_map to map_tests to make it run regularly. Patch #9: add test cases for the issues fixed by patch #3~#5. Please see individual patches for more details. Comments are always welcome. Change Log: v3: * patch #2: remove the unnecessary NULL-init for im_node * patch #6: alloc the leaf node before disabling IRQ to low the possibility of -ENOMEM when leaf_size is large; Free these nodes outside the trie lock (Suggested by Alexei) * collect review and ack tags (Thanks for Toke & Daniel) v2: https://lore.kernel.org/bpf/20241127004641.1118269-1-houtao@huaweicloud.com/ * collect review tags (Thanks for Toke) * drop "Add bpf_mem_cache_is_mergeable() helper" patch * patch #3~#4: add fix tag * patch #4: rename the helper to trie_check_add_elem() and increase n_entries in it. * patch #6: use one bpf mem allocator and update commit message to clarify that using bpf mem allocator is more appropriate. * patch #7: update commit message to add the possible max running time for update operation. * patch #9: update commit message to specify the purpose of these test cases. v1: https://lore.kernel.org/bpf/20241118010808.2243555-1-houtao@huaweicloud.com/ ==================== Link: https://lore.kernel.org/all/20241206110622.1161752-1-houtao@huaweicloud.com/ Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

selftests/bpf: Add more test cases for LPM trie
Add more test cases for LPM trie in test_maps: 1) test_lpm_trie_update_flags It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check whether the return value of update operation is expected. 2) test_lpm_trie_update_full_maps It tests the update operations on a full LPM trie map. Adding new node will fail and overwriting the value of existed node will succeed. 3) test_lpm_trie_iterate_strs and test_lpm_trie_iterate_ints There two test cases test whether the iteration through get_next_key is sorted and expected. These two test cases delete the minimal key after each iteration and check whether next iteration returns the second minimal key. The only difference between these two test cases is the former one saves strings in the LPM trie and the latter saves integers. Without the fix of get_next_key, these two cases will fail as shown below: test_lpm_trie_iterate_strs(1091):FAIL:iterate #2 got abc exp abS test_lpm_trie_iterate_ints(1142):FAIL:iterate #1 got 0x2 exp 0x1 Signed-off-by: Hou Tao <houtao1@huawei.com> Link: https://lore.kernel.org/r/20241206110622.1161752-10-houtao@huaweicloud.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

bpf: Use raw_spinlock_t for LPM trie
After switching from kmalloc() to the bpf memory allocator, there will be no blocking operation during the update of LPM trie. Therefore, change trie->lock from spinlock_t to raw_spinlock_t to make LPM trie usable in atomic context, even on RT kernels. The max value of prefixlen is 2048. Therefore, update or deletion operations will find the target after at most 2048 comparisons. Constructing a test case which updates an element after 2048 comparisons under a 8 CPU VM, and the average time and the maximal time for such update operation is about 210us and 900us.

The program invokes trie_delete_elem(), which then acquires trie->lock. However, it is possible that another process is invoking trie_update_elem(). trie_update_elem() will acquire trie->lock first, then invoke kmalloc_node(). kmalloc_node() may invoke get_partial_node() and try to acquire &n->list_lock (not necessarily the same lock object). Therefore, lockdep warns about the circular locking dependency. Invoking kmalloc() before acquiring trie->lock could fix the warning. However, since BPF programs call be invoked from any context (e.g., through kprobe/tracepoint/fentry), there may still be lock ordering problems for internal locks in kmalloc() or trie->lock itself. To eliminate these potential lock ordering problems with kmalloc()'s internal locks, replacing kmalloc()/kfree()/kfree_rcu() with equivalent BPF memory allocator APIs that can be invoked in any context. The lock ordering problems with trie->lock (e.g., reentrance) will be handled separately. Three aspects of this change require explanation: 1. Intermediate and leaf nodes are allocated from the same allocator. Since the value size of LPM trie is usually small, using a single alocator reduces the memory overhead of the BPF memory allocator. 2. Leaf nodes are allocated before disabling IRQs. This handles cases where leaf_size is large (e.g., > 4KB - 8) and updates require intermediate node allocation. If leaf nodes were allocated in IRQ-disabled region, the free objects in BPF memory allocator would not be refilled timely and the intermediate node allocation may fail. 3. Paired migrate_{disable|enable}() calls for node alloc and free. The BPF memory allocator uses per-CPU struct internally, these paired calls are necessary to guarantee correctness.

bpf: Fix exact match conditions in trie_get_next_key()
trie_get_next_key() uses node->prefixlen == key->prefixlen to identify
an exact match, However, it is incorrect because when the target key
doesn't fully match the found node (e.g., node->prefixlen != matchlen),
these two nodes may also have the same prefixlen. It will return
expected result when the passed key exist in the trie. However when a
recently-deleted key or nonexistent key is passed to
trie_get_next_key(), it may skip keys and return incorrect result.
Fix it by using node->prefixlen == matchlen to identify exact matches.
When the condition is true after the search, it also implies
node->prefixlen equals key->prefixlen, otherwise, the search would
return NULL instead.

When a LPM trie is full, in-place updates of existing elements

bpf: Remove unnecessary check when updating LPM trie
When "node->prefixlen == matchlen" is true, it means that the node is fully matched. If "node->prefixlen == key->prefixlen" is false, it means the prefix length of key is greater than the prefix length of node, otherwise, matchlen will not be equal with node->prefixlen. However, it also implies that the prefix length of node must be less than max_prefixlen. Therefore, "node->prefixlen == trie->max_prefixlen" will always be false when the check of "node->prefixlen == key->prefixlen" returns false. Remove this unnecessary comparison.

blk-mq: move cpuhp callback registering out of q->sysfs_lock
Registering and unregistering cpuhp callback requires global cpu hotplug lock, which is used everywhere. Meantime q->sysfs_lock is used in block layer almost everywhere. It is easy to trigger lockdep warning[1] by connecting the two locks. Fix the warning by moving blk-mq's cpuhp callback registering out of q->sysfs_lock. Add one dedicated global lock for covering registering & unregistering hctx's cpuhp, and it is safe to do so because hctx is guaranteed to be live if our request_queue is live.

x86/cacheinfo: Delete global num_cache_leaves
Linux remembers cpu_cachinfo::num_leaves per CPU, but x86 initializes all CPUs from the same global "num_cache_leaves". This is erroneous on systems such as Meteor Lake, where each CPU has a distinct num_leaves value. Delete the global "num_cache_leaves" and initialize num_leaves on each CPU. init_cache_level() no longer needs to set num_leaves. Also, it never had to set num_levels as it is unnecessary in x86. Keep checking for zero cache leaves. Such condition indicates a bug.

x86/kexec: Restore GDT on return from ::preserve_context kexec
The restore_processor_state() function explicitly states that "the asm code
that gets us here will have restored a usable GDT". That wasn't true in the
case of returning from a ::preserve_context kexec. Make it so.
Without this, the kernel was depending on the called function to reload a
GDT which is appropriate for the kernel before returning.
Test program:
#include <unistd.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <linux/kexec.h>
#include <linux/reboot.h>
#include <sys/reboot.h>
#include <sys/syscall.h>
int main (void)
{
struct kexec_segment segment = {};
unsigned char purgatory[] = {
0x66, 0xba, 0xf8, 0x03, // mov $0x3f8, %dx
0xb0, 0x42, // mov $0x42, %al
0xee, // outb %al, (%dx)
0xc3, // ret
};
int ret;
segment.buf = &purgatory;
segment.bufsz = sizeof(purgatory);
segment.mem = (void *)0x400000;
segment.memsz = 0x1000;
ret = syscall(__NR_kexec_load, 0x400000, 1, &segment, KEXEC_PRESERVE_CONTEXT);
if (ret) {
perror("kexec_load");
exit(1);
}
ret = syscall(__NR_reboot, LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, LINUX_REBOOT_CMD_KEXEC);
if (ret) {
perror("kexec reboot");
exit(1);
}
printf("Success\n");
return 0;
}

iio: magnetometer: yas530: use signed integer type for clamp limits
In the function yas537_measure() there is a clamp_val() with limits of
-BIT(13) and BIT(13) - 1. The input clamp value h[] is of type s32. The
BIT() is of type unsigned long integer due to its define in
include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but
expressed as an unsigned long integer. The size of an unsigned long
integer differs between 32-bit and 64-bit architectures. Converting this
to type s32 may lead to undesired behavior.
Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned
long integer divisor BIT(13) causes an unsigned division, shifting the
left-hand side of the equation back and forth, possibly ending up in large
positive values instead of negative values on 32-bit architectures.
To solve those two issues, declare a signed integer with a value of
BIT(13).
There is another omission in the clamp line: clamp_val() returns a value
and it's going nowhere here. Self-assign it to h[i] to make use of the
clamp macro.
Finally, replace clamp_val() macro by clamp() because after changing the
limits from type unsigned long integer to signed integer it's fine that
way.

sched/numa: fix memory leak due to the overwritten vma->numab_state

When running the hackbench program of LTP, the following memory leak is
reported by kmemleak.

Running with 20*40 (== 800) tasks.

...
This issue can be consistently reproduced on three different servers:
* a 448-core server
* a 256-core server
* a 192-core server
[Root Cause]
Since multiple threads are created by the hackbench program (along with
the command argument 'thread'), a shared vma might be accessed by two or
more cores simultaneously. When two or more cores observe that
vma->numab_state is NULL at the same time, vma->numab_state will be
overwritten.
Although current code ensures that only one thread scans the VMAs in a
single 'numa_scan_period', there might be a chance for another thread
to enter in the next 'numa_scan_period' while we have not gotten till
numab_state allocation [1].
Note that the command `/opt/ltp/testcases/bin/hackbench 50 process 1000`
cannot the reproduce the issue. It is verified with 200+ test runs.
[Solution]
Use the cmpxchg atomic operation to ensure that only one thread executes
the vma->numab_state assignment.

mm/filemap: don't call folio_test_locked() without a reference in next_uptodate_folio()
The folio can get freed + buddy-merged + reallocated in the meantime,
resulting in us calling folio_test_locked() possibly on a tail page.
This makes const_folio_flags VM_BUG_ON_PGFLAGS() when stumbling over the
tail page.
Could this result in other issues? Doesn't look like it. False positives
and false negatives don't really matter, because this folio would get
skipped either way when detecting that they have been reallocated in the
meantime.
Fix it by performing the folio_test_locked() checked after grabbing a
reference. If this ever becomes a real problem, we could add a special
helper that racily checks if the bit is set even on tail pages ... but
let's hope that's not required so we can just handle it cleaner: work on
the folio after we hold a reference.
Do we really need the folio_test_locked() check if we are going to trylock
briefly after? Well, we can at least avoid a xas_reload().
It's a bit unclear which exact change introduced that issue. Likely, ever
since we made PG_locked obey to the PF_NO_TAIL policy it could have been
triggered in some way.

mm/codetag: swap tags when migrate pages
Current solution to adjust codetag references during page migration is
done in 3 steps:
1. sets the codetag reference of the old page as empty (not pointing
to any codetag);
2. subtracts counters of the new page to compensate for its own
allocation;
3. sets codetag reference of the new page to point to the codetag of
the old page.
This does not work if CONFIG_MEM_ALLOC_PROFILING_DEBUG=n because
set_codetag_empty() becomes NOOP. Instead, let's simply swap codetag
references so that the new page is referencing the old codetag and the old
page is referencing the new codetag. This way accounting stays valid and
the logic makes more sense.

stackdepot: fix stack_depot_save_flags() in NMI context
Per documentation, stack_depot_save_flags() was meant to be usable from
NMI context if STACK_DEPOT_FLAG_CAN_ALLOC is unset. However, it still
would try to take the pool_lock in an attempt to save a stack trace in the
current pool (if space is available).
This could result in deadlock if an NMI is handled while pool_lock is
already held. To avoid deadlock, only try to take the lock in NMI context
and give up if unsuccessful.
The documentation is fixed to clearly convey this.
