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> |

selftests/bpf: Move test_lpm_map.c to map_tests
Move test_lpm_map.c to map_tests/ to include LPM trie test cases in regular test_maps run. Most code remains unchanged, including the use of assert(). Only reduce n_lookups from 64K to 512, which decreases test_lpm_map runtime from 37s to 0.7s.

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.

bpf: Handle in-place update for full LPM trie correctly
When a LPM trie is full, in-place updates of existing elements
incorrectly return -ENOSPC.
Fix this by deferring the check of trie->n_entries. For new insertions,
n_entries must not exceed max_entries. However, in-place updates are
allowed even when the trie is full.

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.

tracing fixes for v6.13:
- Fix trace histogram sort function cmp_entries_dup() The sort function cmp_entries_dup() returns either 1 or 0, and not -1 if parameter "a" is less than "b" by memcmp(). - Fix archs that call trace_hardirqs_off() without RCU watching Both x86 and arm64 no longer call any tracepoints with RCU not watching. It was assumed that it was safe to get rid of trace_*_rcuidle() version of the tracepoint calls.

arm64: ptrace: fix partial SETREGSET for NT_ARM_GCS
Currently gcs_set() doesn't initialize the temporary 'user_gcs'
variable, and a SETREGSET call with a length of 0, 8, or 16 will leave
some portion of this uninitialized. Consequently some arbitrary
uninitialized values may be written back to the relevant fields in task
struct, potentially leaking up to 192 bits of memory from the kernel
stack. The read is limited to a specific slot on the stack, and the
issue does not provide a write mechanism.
As gcs_set() rejects cases where user_gcs::features_enabled has bits set
other than PR_SHADOW_STACK_SUPPORTED_STATUS_MASK, a SETREGSET call with
a length of zero will randomly succeed or fail depending on the value of
the uninitialized value, it isn't possible to leak the full 192 bits.
With a length of 8 or 16, user_gcs::features_enabled can be initialized
to an accepted value, making it practical to leak 128 or 64 bits.
Fix this by initializing the temporary value before copying the regset
from userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,
NT_ARM_SYSTEM_CALL). In the case of a zero-length or partial write, the
existing contents of the fields which are not written to will be
retained.
To ensure that the extraction and insertion of fields is consistent
across the GETREGSET and SETREGSET calls, new task_gcs_to_user() and
task_gcs_from_user() helpers are added, matching the style of
pac_address_keys_to_user() and pac_address_keys_from_user().

arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRL
Currently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl'
variable, and a SETREGSET call with a length of zero will leave this
uninitialized. Consequently tagged_addr_ctrl_set() will consume an
arbitrary value, potentially leaking up to 64 bits of memory from the
kernel stack. The read is limited to a specific slot on the stack, and
the issue does not provide a write mechanism.
As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero and
rejects other values, a partial SETREGSET attempt will randomly succeed
or fail depending on the value of the uninitialized value, and the
exposure is significantly limited.
Fix this by initializing the temporary value before copying the regset
from userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,
NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existing
value of the tagged address ctrl will be retained.
The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in the
user_aarch64_view used by a native AArch64 task to manipulate another
native AArch64 task. As get_tagged_addr_ctrl() only returns an error
value when called for a compat task, tagged_addr_ctrl_get() and
tagged_addr_ctrl_set() should never observe an error value from
get_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate that
such an error would be unexpected, and error handlnig is not missing in
either case.

drm/v3d: Enable Performance Counters before clearing them
On the Raspberry Pi 5, performance counters are not being cleared
when `v3d_perfmon_start()` is called, even though we write to the
CLR register. As a result, their values accumulate until they
overflow.
The expected behavior is for performance counters to reset to zero
at the start of a job. When the job finishes and the perfmon is
stopped, the counters should accurately reflect the values for that
specific job.
To ensure this behavior, the performance counters are now enabled
before being cleared. This allows the CLR register to function as
intended, zeroing the counter values when the job begins.
