UPSTREAM: posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
commit f90fff1e152dedf52b932240ebbd670d83330eca upstream.
If an exiting non-autoreaping task has already passed exit_notify() and
calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent
or debugger right after unlock_task_sighand().
If a concurrent posix_cpu_timer_del() runs at that moment, it won't be
able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or
lock_task_sighand() will fail.
Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.
This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because
exit_task_work() is called before exit_notify(). But the check still
makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail
anyway in this case.

ANDROID: 16K: Don't copy data vma for maps/smaps output
Remove get_data_vma() which made a copy of the original VMA containing padding and modified vm_end to exclude the trailing padding (if any). Avoid this copy to avoid races due to stale data relating to vma->vm_file. Instead use VMA_PAD_START(vma) directly to get the correct end excluding padding if any. Add additional check to verify the padding VMA is as expected and also check for allocation failure of the pad VMA. ELFs with padding can be loaded from tmpfs. For simplicity swapped out shmem accounting in smaps, skips the fast path for read only files and walks the page table with the range adjusted for padding.

ANDROID: BACKPORT: KVM: arm64: Always unmap the pvmfw region at stage-2
The donation of the pvmfw region to pKVM is currently done transparently as part of fix_host_ownership(). However, this function only runs over PA ranges covered by the memblock list, although there is no guarantee for the pvmfw region to be advertised in a memory node in DT. In this case, the pKVM init will appear to succeed while silently keeping valid host stage-2 mappings to the pvmfw region. Fix this by forcefully registering the pvmfw region in the pKVM memblock list. BACKPORT: Fix usage of pvmfw_size and pvmfw_base which are pointers in 6.6 and earlier.

Revert "ANDROID: mm: Set PAGE_BLOCK_ORDER to 8 when ARM64_16K_PAGES"
This reverts commit 45afa562802ae9a253ef437dd0010c8c2ec17806. Reason for revert: This was a workaround due to the kernel build tools preserving the # nocheck comment as part of the config option for CONFIG_PAGE_BLOCK_ORDER, which is problematic, since it is supposed to be an int. The build tools have been patched to not do that anymore, so this can be removed.

BACKPORT: FROMGIT: mm: Add CONFIG_PAGE_BLOCK_ORDER to select page block order
Problem: On large page size configurations (16KiB, 64KiB), the CMA
alignment requirement (CMA_MIN_ALIGNMENT_BYTES) increases considerably,
and this causes the CMA reservations to be larger than necessary.
This means that system will have less available MIGRATE_UNMOVABLE and
MIGRATE_RECLAIMABLE page blocks since MIGRATE_CMA can't fallback to them.
The CMA_MIN_ALIGNMENT_BYTES increases because it depends on
MAX_PAGE_ORDER which depends on ARCH_FORCE_MAX_ORDER. The value of
ARCH_FORCE_MAX_ORDER increases on 16k and 64k kernels.
For example, in ARM, the CMA alignment requirement when:
- CONFIG_ARCH_FORCE_MAX_ORDER default value is used
- CONFIG_TRANSPARENT_HUGEPAGE is set:
PAGE_SIZE | MAX_PAGE_ORDER | pageblock_order | CMA_MIN_ALIGNMENT_BYTES
-----------------------------------------------------------------------
4KiB | 10 | 9 | 4KiB * (2 ^ 9) = 2MiB
16Kib | 11 | 11 | 16KiB * (2 ^ 11) = 32MiB
64KiB | 13 | 13 | 64KiB * (2 ^ 13) = 512MiB
There are some extreme cases for the CMA alignment requirement when:
- CONFIG_ARCH_FORCE_MAX_ORDER maximum value is set
- CONFIG_TRANSPARENT_HUGEPAGE is NOT set:
- CONFIG_HUGETLB_PAGE is NOT set
PAGE_SIZE | MAX_PAGE_ORDER | pageblock_order | CMA_MIN_ALIGNMENT_BYTES
------------------------------------------------------------------------
4KiB | 15 | 15 | 4KiB * (2 ^ 15) = 128MiB
16Kib | 13 | 13 | 16KiB * (2 ^ 13) = 128MiB
64KiB | 13 | 13 | 64KiB * (2 ^ 13) = 512MiB
This affects the CMA reservations for the drivers. If a driver in a
4KiB kernel needs 4MiB of CMA memory, in a 16KiB kernel, the minimal
reservation has to be 32MiB due to the alignment requirements:
reserved-memory {
...
cma_test_reserve: cma_test_reserve {
compatible = "shared-dma-pool";
size = <0x0 0x400000>; /* 4 MiB */
...
};
};
reserved-memory {
...
cma_test_reserve: cma_test_reserve {
compatible = "shared-dma-pool";
size = <0x0 0x2000000>; /* 32 MiB */
...
};
};
Solution: Add a new config CONFIG_PAGE_BLOCK_ORDER that
allows to set the page block order in all the architectures.
The maximum page block order will be given by
ARCH_FORCE_MAX_ORDER.
By default, CONFIG_PAGE_BLOCK_ORDER will have the same
value that ARCH_FORCE_MAX_ORDER. This will make sure that
current kernel configurations won't be affected by this
change. It is a opt-in change.
This patch will allow to have the same CMA alignment
requirements for large page sizes (16KiB, 64KiB) as that
in 4kb kernels by setting a lower pageblock_order.
Tests:
- Verified that HugeTLB pages work when pageblock_order is 1, 7, 10
on 4k and 16k kernels.
- Verified that Transparent Huge Pages work when pageblock_order
is 1, 7, 10 on 4k and 16k kernels.
- Verified that dma-buf heaps allocations work when pageblock_order
is 1, 7, 10 on 4k and 16k kernels.
Benchmarks:
The benchmarks compare 16kb kernels with pageblock_order 10 and 7. The
reason for the pageblock_order 7 is because this value makes the min
CMA alignment requirement the same as that in 4kb kernels (2MB).
- Perform 100K dma-buf heaps (/dev/dma_heap/system) allocations of
SZ_8M, SZ_4M, SZ_2M, SZ_1M, SZ_64, SZ_8, SZ_4. Use simpleperf
(https://developer.android.com/ndk/guides/simpleperf) to measure
the # of instructions and page-faults on 16k kernels.
The benchmark was executed 10 times. The averages are below:
# instructions | #page-faults
order 10 | order 7 | order 10 | order 7

BACKPORT: binder: Create safe versions of binder log files
Binder defines several seq_files that can be accessed via debugfs or binderfs. Some of these files (e.g., 'state' and 'transactions') contain more granular information about binder's internal state that is helpful for debugging, but they also leak userspace address data through user-defined 'cookie' or 'ptr' values. Consequently, access to these files must be heavily restricted. Add two new files, 'state_hashed' and 'transactions_hashed', that reproduce the information in the original files but use the kernel's raw pointer obfuscation to hash any potential user addresses. This approach allows systems to grant broader access to the new files without having to change the security policy around the existing ones. In practice, userspace populates these fields with user addresses, but within the driver, these values only serve as unique identifiers for their associated binder objects. Consequently, binder logs can obfuscate these values and still retain meaning. While this strategy prevents leaking information about the userspace memory layout in the existing log files, it also decouples log messages about binder objects from their user-defined identifiers.

UPSTREAM: binder: Refactor binder_node print synchronization
The binder driver outputs information about each dead binder node by iterating over the dead nodes list, and it prints the state of each live node in the system by traversing each binder_proc's proc->nodes tree. Both cases require similar logic to maintain the global lock ordering while accessing each node. Create a helper function to synchronize around printing binder nodes in a list. Opportunistically make minor cosmetic changes to binder print functions. Acked-by: Carlos Llamas <cmllamas@google.com> Signed-off-by: "Tiffany Y.

FROMGIT: scsi: core: ufs: Fix a hang in the error handler
ufshcd_err_handling_prepare() calls ufshcd_rpm_get_sync(). The latter
function can only succeed if UFSHCD_EH_IN_PROGRESS is not set because
resuming involves submitting a SCSI command and ufshcd_queuecommand()
returns SCSI_MLQUEUE_HOST_BUSY if UFSHCD_EH_IN_PROGRESS is set. Fix this
hang by setting UFSHCD_EH_IN_PROGRESS after ufshcd_rpm_get_sync() has
been called instead of before.

BACKPORT: erofs: allocate more short-lived pages from reserved pool first
This patch aims to allocate bvpages and short-lived compressed pages
from the reserved pool first.
After applying this patch, there are three benefits.
1. It reduces the page allocation time.
The bvpages and short-lived compressed pages account for about 4% of
the pages allocated from the system in the multi-app launch benchmarks
[1]. It reduces the page allocation time accordingly and lowers the
likelihood of blockage by page allocation in low memory scenarios.
2. The pages in the reserved pool will be allocated on demand.
Currently, bvpages and short-lived compressed pages are short-lived
pages allocated from the system, and the pages in the reserved pool all
originate from short-lived pages. Consequently, the number of reserved
pool pages will increase to z_erofs_rsv_nrpages over time.
With this patch, all short-lived pages are allocated from the reserved
pool first, so the number of reserved pool pages will only increase when
there are not enough pages. Thus, even if z_erofs_rsv_nrpages is set to
a large number for specific reasons, the actual number of reserved pool
pages may remain low as per demand. In the multi-app launch benchmarks
[1], z_erofs_rsv_nrpages is set at 256, while the number of reserved
pool pages remains below 64.
3. When erofs cache decompression is disabled
(EROFS_ZIP_CACHE_DISABLED), all pages will *only* be allocated from
the reserved pool for erofs. This will significantly reduce the memory
pressure from erofs.
[1] For additional details on the multi-app launch benchmarks, please
refer to commit 0f6273ab4637 ("erofs: add a reserved buffer pool for lz4
decompression").

NFS: Avoid flushing data while holding directory locks in nfs_rename()
[ Upstream commit dcd21b609d4abc7303f8683bce4f35d78d7d6830 ] The Linux client assumes that all filehandles are non-volatile for renames within the same directory (otherwise sillyrename cannot work). However, the existence of the Linux 'subtree_check' export option has meant that nfs_rename() has always assumed it needs to flush writes before attempting to rename. Since NFSv4 does allow the client to query whether or not the server exhibits this behaviour, and since knfsd does actually set the appropriate flag when 'subtree_check' is enabled on an export, it should be OK to optimise away the write flushing behaviour in the cases where it is clearly not needed.

spi: spi-sun4i: fix early activation
[ Upstream commit fb98bd0a13de2c9d96cb5c00c81b5ca118ac9d71 ] The SPI interface is activated before the CPOL setting is applied. In that moment, the clock idles high and CS goes low. After a short delay, CPOL and other settings are applied, which may cause the clock to change state and idle low. This transition is not part of a clock cycle, and it can confuse the receiving device. To prevent this unexpected transition, activate the interface while CPOL and the other settings are being applied.

um: let 'make clean' properly clean underlying SUBARCH as well
[ Upstream commit ab09da75700e9d25c7dfbc7f7934920beb5e39b9 ] Building the kernel with O= is affected by stale in-tree build artifacts. So, if the source tree is not clean, Kbuild displays the following: $ make ARCH=um O=build defconfig make[1]: Entering directory '/.../linux/build' *** *** The source tree is not clean, please run 'make ARCH=um mrproper' *** in /.../linux *** make[2]: *** [/.../linux/Makefile:673: outputmakefile] Error 1 make[1]: *** [/.../linux/Makefile:248: __sub-make] Error 2 make[1]: Leaving directory '/.../linux/build' make: *** [Makefile:248: __sub-make] Error 2 Usually, running 'make mrproper' is sufficient for cleaning the source tree for out-of-tree builds. However, building UML generates build artifacts not only in arch/um/, but also in the SUBARCH directory (i.e., arch/x86/). If in-tree stale files remain under arch/x86/, Kbuild will reuse them instead of creating new ones under the specified build directory. This commit makes 'make ARCH=um clean' recurse into the SUBARCH directory.

nfs: don't share pNFS DS connections between net namespaces
[ Upstream commit 6b9785dc8b13d9fb75ceec8cf4ea7ec3f3b1edbc ] Currently, different NFS clients can share the same DS connections, even when they are in different net namespaces. If a containerized client creates a DS connection, another container can find and use it. When the first client exits, the connection will close which can lead to stalls in other clients. Add a net namespace pointer to struct nfs4_pnfs_ds, and compare those value to the caller's netns in _data_server_lookup_locked() when searching for a nfs4_pnfs_ds to match.

coredump: hand a pidfd to the usermode coredump helper
commit b5325b2a270fcaf7b2a9a0f23d422ca8a5a8bdea upstream. Give userspace a way to instruct the kernel to install a pidfd into the usermode helper process. This makes coredump handling a lot more reliable for userspace. In parallel with this commit we already have systemd adding support for this in [1]. We create a pidfs file for the coredumping process when we process the corename pattern. When the usermode helper process is forked we then install the pidfs file as file descriptor three into the usermode helpers file descriptor table so it's available to the exec'd program. Since usermode helpers are either children of the system_unbound_wq workqueue or kthreadd we know that the file descriptor table is empty and can thus always use three as the file descriptor number. Note, that we'll install a pidfd for the thread-group leader even if a subthread is calling do_coredump(). We know that task linkage hasn't been removed due to delay_group_leader() and even if this @current isn't the actual thread-group leader we know that the thread-group leader cannot be reaped until @current has exited. [brauner: This is a backport for the v6.1 series. Upstream has significantly changed and backporting all that infra is a non-starter. So simply backport the pidfd_prepare() helper and waste the file descriptor we allocated. Then we minimally massage the umh coredump setup code.] Link: https://github.com/systemd/systemd/pull/37125 [1] Link: https://lore.kernel.org/20250414-work-coredump-v2-3-685bf231f828@kernel.org Tested-by: Luca Boccassi <luca.boccassi@gmail.com> Reviewed-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Christian Brauner <brauner@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
