commit 42316941335644a98335f209daafa4c122f28983 upstream.
The type defined for the BINDER_SET_MAX_THREADS ioctl was changed from
size_t to __u32 in order to avoid incompatibility issues between 32 and
64-bit kernels. However, the internal types used to copy from user and
store the value were never updated. Use u32 to fix the inconsistency.

commit aaef73821a3b0194a01bd23ca77774f704a04d40 upstream.
Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying
txn") introduced changes to how binder objects are copied. In doing so,
it unintentionally removed an offset alignment check done through calls
to binder_alloc_copy_from_buffer() -> check_buffer().
These calls were replaced in binder_get_object() with copy_from_user(),
so now an explicit offset alignment check is needed here. This avoids
later complications when unwinding the objects gets harder.
It is worth noting this check existed prior to commit 7a67a39320
("binder: add function to copy binder object from buffer"), likely
removed due to redundancy at the time.

Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying
txn") introduced changes to how binder objects are copied. In doing so,
it unintentionally removed an offset alignment check done through calls
to binder_alloc_copy_from_buffer() -> check_buffer().
These calls were replaced in binder_get_object() with copy_from_user(),
so now an explicit offset alignment check is needed here. This avoids
later complications when unwinding the objects gets harder.
It is worth noting this check existed prior to commit 7a67a39320
("binder: add function to copy binder object from buffer"), likely
removed due to redundancy at the time.

path_lookupat() is capable of safely reading unampped VAs. If an
unmapped VA is read whilst the function is being called, the resulting
page fault will get re-directed to __do_page_fault(), which will call
fixup_exception() to handle the aforementioned unmapped VA read.
Now, for an OS running in a VM, let's say that memory was still mapped
at S1 but lent to another VM (i.e. unmapped at S2 for the given VM).
The reading of an unmapped VA in path_lookupat() still needs to be
handled. For hypervisors that inject an abort leading to a do_sea()
call, call fixup_exception() from do_sea() if
trace_android_vh_try_fixup_sea() indicates that we can do so.

When cpu loading is high, the task maybe preempted after restoring the
sched priority in trace_android_vh_binder_free_buf(). This means that
node->has_async_transaction can't be cleared immediately and the work
isn't added to the proc->todo queue as soon as possible.
To fix this we add a new hook trace_android_vh_binder_buffer_release()
to restore the priority after node->has_async_transaction has been
updated and the node->work has been added to the proc->todo queue.
Note: the old trace_android_vh_binder_free_buf() hook is kept to avoid
breaking KMI but is not extrictly needed.

commit 97830f3c3088638ff90b20dfba2eb4d487bf14d7 upstream.
In (e)poll mode, threads often depend on I/O events to determine when
data is ready for consumption. Within binder, a thread may initiate a
command via BINDER_WRITE_READ without a read buffer and then make use
of epoll_wait() or similar to consume any responses afterwards.
It is then crucial that epoll threads are signaled via wakeup when they
queue their own work. Otherwise, they risk waiting indefinitely for an
event leaving their work unhandled. What is worse, subsequent commands
won't trigger a wakeup either as the thread has pending work.

Since SPF is an out-of-tree feature, the risks of changing its behavior
are higher. Add a vendor hook to enable speculative swap pagefaults. By
default it's disabled and should not cause troubles for current users.

(cherry picked from commit 6c3dd25d2fdeff6fc752ef74e87e22f86ae1d939)
In some situations, we want to adjust the alloc_flags for better performance.
more detail explain:
the reason why we add a vendor hook adjusting alloc_flags:
1 the user only pass parameter size and gfp_flags once. if we mask the
__GFP_RECLAIM, we can't distinguish high-order and low-order, they all
will not rise reclaim behavior, it's wrong.
2 for __iommu_dma_alloc_pages, there is a loop to try to alloc pages from
high-order to low-order fallback, and we add hook callsite to only change
the high-order( > costly order) alloc behavior(which high probability will
result more overhead than benifit).
which allow low order alloc to do reclaim behavior still, otherwise may
end up with alloc fail.
3 in android ION(drivers/dma-buf/heaps/system_heap.c )
there is same logic, high-order alloc will not do reclaim behavior.
so this change add a vendor hook for adjusting alloc_flags, and add a
callsite in __iommu_dma_alloc_pages to turn the reclaim behavior.

commit 9a9ab0d963621d9d12199df9817e66982582d5a5 upstream.
Task A calls binder_update_page_range() to allocate and insert pages on
a remote address space from Task B. For this, Task A pins the remote mm
via mmget_not_zero() first. This can race with Task B do_exit() and the
final mmput() refcount decrement will come from Task A.
Task A | Task B
------------------+------------------
mmget_not_zero() |
| do_exit()
| exit_mm()
| mmput()
mmput() |
exit_mmap() |
remove_vma() |
fput() |
In this case, the work of ____fput() from Task B is queued up in Task A
as TWA_RESUME. So in theory, Task A returns to userspace and the cleanup
work gets executed. However, Task A instead sleep, waiting for a reply
from Task B that never comes (it's dead).
This means the binder_deferred_release() is blocked until an unrelated
binder event forces Task A to go back to userspace. All the associated
death notifications will also be delayed until then.
In order to fix this use mmput_async() that will schedule the work in
the corresponding mm->async_put_work WQ instead of Task A.

commit 3f489c2067c5824528212b0fc18b28d51332d906 upstream.
The mmap read lock is used during the shrinker's callback, which means
that using alloc->vma pointer isn't safe as it can race with munmap().
As of commit dd2283f260 ("mm: mmap: zap pages with read mmap_sem in
munmap") the mmap lock is downgraded after the vma has been isolated.
I was able to reproduce this issue by manually adding some delays and
triggering page reclaiming through the shrinker's debug sysfs. The
following KASAN report confirms the UAF:

Fix this issue by performing instead a vma_lookup() which will fail to
find the vma that was isolated before the mmap lock downgrade. Note that
this option has better performance than upgrading to a mmap write lock
which would increase contention. Plus, mmap_write_trylock() has been
recently removed anyway.

commit c6d05e0762ab276102246d24affd1e116a46aa0c upstream.
Each transaction is associated with a 'struct binder_buffer' that stores
the metadata about its buffer area. Since commit 74310e06be ("android:
binder: Move buffer out of area shared with user space") this struct is
no longer embedded within the buffer itself but is instead allocated on
the heap to prevent userspace access to this driver-exclusive info.
Unfortunately, the space of this struct is still being accounted for in
the total buffer size calculation, specifically for async transactions.
This results in an additional 104 bytes added to every async buffer
request, and this area is never used.
This wasted space can be substantial. If we consider the maximum mmap
buffer space of SZ_4M, the driver will reserve half of it for async
transactions, or 0x200000. This area should, in theory, accommodate up
to 262,144 buffers of the minimum 8-byte size. However, after adding
the extra 'sizeof(struct binder_buffer)', the total number of buffers
drops to only 18,724, which is a sad 7.14% of the actual capacity.
This patch fixes the buffer size calculation to enable the utilization
of the entire async buffer space. This is expected to reduce the number
of -ENOSPC errors that are seen on the field.

commit 1aa3aaf8953c84bad398adf6c3cabc9d6685bf7d upstream
A transaction complete work is allocated and queued for each
transaction. Under certain conditions the work->type might be marked as
BINDER_WORK_TRANSACTION_ONEWAY_SPAM_SUSPECT to notify userspace about
potential spamming threads or as BINDER_WORK_TRANSACTION_PENDING when
the target is currently frozen.
However, these work types are not being handled in binder_release_work()
so they will leak during a cleanup. This was reported by syzkaller with
the following kmemleak dump:

Add hooks to support oem's binder feature of improving binder_thread->task sched priority
1) Check if it is a specific task in trace_android_vh_alloc_oem_binder_struct() and store the flag to t->android_vendor_data1
2) If it is a specific binder task and binder_thread selected, raise the sched priority of binder_thread->task in runqueue.
3) If it is a specific binder task but no binder_thread selected (e.g pending_async or no free threads), insert t->work to the appropriate position in the list.
4) Reset the sched priority when BR_TRANSACTION or BC_FREE_BUFFER.
Some high-priority async binder task reset the sched priority when BC_FREE_BUFFER in trace_android_vh_binder_free_buf().
Some middle-priority async binder task reset the sched priority when driver return server "BR_TRANSACTION" in trace_android_vh_binder_transaction_received().

We introduce an interrupt hook in Android to manage memory compression
using madvise, improving user experience.
Currently, when a user returns to the home screen, memory compression is
triggered using madvise. The vma and PAGEOUT flag are sent to
process_madvise, initiating page reclaim.
However, if an app is re-opened soon after starting compression, the
reclaim process can cause read delays, leading to potential lag.
To resolve this, we propose to skip pte range traversal. By comparing
the vma's task uid with the current app's uid, we can identify and
interrupt the madvise operation for that vma.
Implementing this requires a vendor hook for should_end_madvise. This
allows us to skip traversal, enhancing user experience.

The analysis shows that when we iterate the swap_avail_heads list, we get
node A, but before we access node A, node A is maybe deleted, and by the time
we actually access node A, it no longer exists, as follows:
CPU1 thread1 CPU2 thread2
plist_for_each_entry_safe()
get si->avail_lists[node] from swap_avail_heads
remove si->avail_lists[node] from swap_avail_heads
plist_requeue(&si->avail_lists[node])
BUG_ON(plist_node_empty(node)); // trigger
Due to when we use vendor hook of get_swap_page, the get_swap_pages() function
is overridden, use our own spin_lock to protect when iterate swap_avail_heads
list, but now use native swap_avail_lock spin_lock protect when the
swap_avail_heads list to add and delete nodes, so there will be concurrent
access.
So add vendor hook of add/delete/iterate node for avail_list, in this way, we
can use our own spin_lock to protect the swap_avail_heads list to add, delete
and iterate node.
Due to enable_swap_info function to call vendor hook of add_to_avail_list,
need first init swap_avail_heads, so also add vendor hook of
swap_avail_heads_init.
Due to the vendor hook of __cgroup_throttle_swaprate need to call
blkcg_schedule_throttle function, so export it also.

Implemented a hook to check if battery swap is enabled in
alarm timer suspend routine. During a battery swap, it is
crucial to ensure that the device remains in a suspended
state, relying on a limited backup power source. It is
essential to prevent any unintended awakenings in this
state, as they could potentially lead to sudden surges
in the power consumption, ultimately resulting in a
device shutdown. Hence, we disable alarmtimer IRQs when
in batteryswap mode.

We need to abort the reclaim/compaction by sending
signal(such as SIGUSR2) to the reclaim thread, or
just abort when cpu-usage is too-high or free-mem is enough.

(cherry picked from commit 024628cc9203cbd4f8471d98435b3a3d6f85764d)
In some situations, we want to decrease readaround size for better
performance. So we add this hook.

memory allocations
We add these hooks to avoid key threads blocked in memory allocation
path.
-android_vh_free_unref_page_bypass ----We create a memory pool for the key threads. This hook determines whether a page should be free to the pool or to buddy freelist. It works with a existing hook `android_vh_alloc_pages_reclaim_bypass`, which takes pages out of the pool.
-android_vh_kvmalloc_node_use_vmalloc ----For key threads, we perfer not to run into direct reclaim. So we clear __GFP_DIRECT_RECLAIM flag. For threads which are not that important, we perfer use vmalloc.
-android_vh_should_alloc_pages_retry ----Before key threads run into direct reclaim, we want to retry with a lower watermark.
-android_vh_unreserve_highatomic_bypass ----We want to keep more highatomic pages when unreserve them to avoid highatomic allocation failures.
-android_vh_pageset_update ----We found the default per-cpu pageset is quite few in smartphones with large ram size. This hook is used to increase it to reduce zone->lock contentions.
-android_vh_rmqueue_bulk_bypass ----We found sometimes when key threads run into rmqueue_bulk, it took several milliseconds spinning at zone->lock or filling per-cpu pages. We use this hook to take pages from the mempool mentioned above, rather than grab zone->lock and fill a batch of pages to per-cpu.

commit bdc1c5fac982845a58d28690cdb56db8c88a530d upstream.
In binder_transaction_buffer_release() the 'failed_at' offset indicates
the number of objects to clean up. However, this function was changed by
commit 44d8047f1d ("binder: use standard functions to allocate fds"),
to release all the objects in the buffer when 'failed_at' is zero.
This introduced an issue when a transaction buffer is released without
any objects having been processed so far. In this case, 'failed_at' is
indeed zero yet it is misinterpreted as releasing the entire buffer.
This leads to use-after-free errors where nodes are incorrectly freed
and subsequently accessed. Such is the case in the following KASAN
report:
