Being interrupted by a signal during binder ioctls is not unusual.
Commit 218225c05beaf02320f05a9b3b7041e27a0684f7 changed the interrupted
ioctl return code from ERESTARTSYS to EINTR, but the error logging check
was never updated:
[ 352.090265] binder: 6534:6552 ioctl c0306201 7a0f9fea10 returned -4
[ 352.090393] binder: 6534:7670 ioctl c0306201 7a6489da10 returned -4
[ 352.090432] binder: 6534:9501 ioctl c0306201 7a61377a10 returned -4
Update the return code to fix the log spam.
[orges]: this is not actually a duplicate commit. the log is pretty much
the same except it returns -512

In binder, using GFP_HIGHMEM will result in the allocated memory
not to be mapped in the kernel's virtual address space.
This prevents the kernel from being capable of directly
referring it.

Most of binder's memory allocations are tiny, and they're allocated
and freed extremely frequently. The latency from going through the page
allocator all the time for such small allocations ends up being quite
high, especially when the system is low on memory. Binder is
performance-critical, so this is suboptimal.
Instead of using kzalloc to allocate a struct every time, reserve caches
specifically for allocating each struct quickly.

Provide userspace with a mechanism to discover features supported by
the binder driver to refrain from using any unsupported ones in the
first place. Starting with "oneway_spam_detection" only new features
are to be listed under binderfs and all previous ones are assumed to
be supported.
Assuming an instance of binderfs has been mounted at /dev/binderfs,
binder feature files can be found under /dev/binderfs/features/.
Usage example:
$ mkdir /dev/binderfs
$ mount -t binder binder /dev/binderfs
$ cat /dev/binderfs/features/oneway_spam_detection

The function close_fd_get_file is explicitly a variant of
__close_fd[1]. Now that __close_fd has been renamed close_fd, rename
close_fd_get_file to be consistent with close_fd.
When __alloc_fd, __close_fd and __fd_install were introduced the
double underscore indicated that the function took a struct
files_struct parameter. The function __close_fd_get_file never has so
the naming has always been inconsistent. This just cleans things up
so there are not any lingering mentions or references __close_fd left
in the code.

Commit e00eb41c0c7b ("ANDROID: binder: add support for RT prio
inheritance.") added the use of MAX_USER_RT_PRIO to the binder.c code,
but that commit was never sent upstream.
In commit ae18ad281e82 ("sched: Remove MAX_USER_RT_PRIO"), that define
was taken away, so to fix up the build breakage, move the binder code to
use MAX_RT_PRIO instead of the now-removed MAX_USER_RT_PRIO define.
Hopefully this is correct, who knows, it's binder RT code! :)

Setting sender_euid using proc->cred caused some Android system test

commit 29bc22ac5e5bc63275e850f0c8fc549e3d0e306b upstream.
Save the 'struct cred' associated with a binder process
at initial open to avoid potential race conditions
when converting to an euid.
Set a transaction's sender_euid from the 'struct cred'
saved at binder_open() instead of looking up the euid
from the binder proc's 'struct task'. This ensures
the euid is associated with the security context that
of the task that opened binder.

The most common cause of the binder transaction buffer filling up is a
client rapidly firing oneway transactions into a process, before it has
a chance to handle them. Yet the root cause of this is often hard to
debug, because either the system or the app will stop, and by that time
binder debug information we dump in bugreports is no longer relevant.
This change warns as soon as a process dips below 80% of its oneway
space (less than 100kB available in the configuration), when any one
process is responsible for either more than 50 transactions, or more
than 50% of the oneway space.

A transaction of type BINDER_TYPE_WEAK_HANDLE can fail to increment the
reference for a node. In this case, the target proc normally releases
the failed reference upon close as expected. However, if the target is
dying in parallel the call will race with binder_deferred_release(), so
the target could have released all of its references by now leaving the
cleanup of the new failed reference unhandled.
The transaction then ends and the target proc gets released making the
ref->proc now a dangling pointer. Later on, ref->node is closed and we
attempt to take spin_lock(&ref->proc->inner_lock), which leads to the
use-after-free bug reported below. Let's fix this by cleaning up the
failed reference on the spot instead of relying on the target to do so.

commit a880b28a71e39013e357fd3adccd1d8a31bc69a8 upstream.
wake_up_poll() uses nr_exclusive=1, so it's not guaranteed to wake up
all exclusive waiters. Yet, POLLFREE *must* wake up all waiters. epoll
and aio poll are fortunately not affected by this, but it's very
fragile. Thus, the new function wake_up_pollfree() has been introduced.
Convert binder to use wake_up_pollfree().

This is a partial revert of commit
29bc22ac5e5b ("binder: use euid from cred instead of using task").
Setting sender_euid using proc->cred caused some Android system test
regressions that need further investigation. It is a partial

commit 52f88693378a58094c538662ba652aff0253c4fe upstream.
Since binder was integrated with selinux, it has passed
'struct task_struct' associated with the binder_proc
to represent the source and target of transactions.
The conversion of task to SID was then done in the hook
implementations. It turns out that there are race conditions
which can result in an incorrect security context being used.
Fix by using the 'struct cred' saved during binder_open and pass
it to the selinux subsystem.

When releasing a thread todo list when tearing down
a binder_proc, the following race was possible which
could result in a use-after-free:
1. Thread 1: enter binder_release_work from binder_thread_release
2. Thread 2: binder_update_ref_for_handle() calls binder_dec_node_ilocked()
3. Thread 2: dec nodeA --> 0 (will free node)
4. Thread 1: ACQ inner_proc_lock
5. Thread 2: block on inner_proc_lock
6. Thread 1: dequeue work (BINDER_WORK_NODE, part of nodeA)
7. Thread 1: REL inner_proc_lock

10. Thread 2: free node
11. Thread 2: REL inner_proc_lock
12. Thread 1: deref w->type (UAF)
The problem was that for a BINDER_WORK_NODE, the binder_work element
must not be accessed after releasing the inner_proc_lock while
processing the todo list elements since another thread might be
handling a deref on the node containing the binder_work element
leading to the node being freed.

Binder is designed such that a binder_proc never has references to
itself. If this rule is violated, memory corruption can occur when a
process sends a transaction to itself; see e.g.
<https://syzkaller.appspot.com/bug?extid=09e05aba06723a94d43d>.
There is a remaining edgecase through which such a transaction-to-self
can still occur from the context of a task with BINDER_SET_CONTEXT_MGR
access:
- task A opens /dev/binder twice, creating binder_proc instances P1
and P2
- P1 becomes context manager
- P2 calls ACQUIRE on the magic handle 0, allocating index 0 in its
handle table
- P1 dies (by closing the /dev/binder fd and waiting a bit)
- P2 becomes context manager
- P2 calls ACQUIRE on the magic handle 0, allocating index 1 in its
handle table
[this triggers a warning: "binder: 1974:1974 tried to acquire
reference to desc 0, got 1 instead"]
- task B opens /dev/binder once, creating binder_proc instance P3
- P3 calls P2 (via magic handle 0) with (void*)1 as argument (two-way
transaction)
- P2 receives the handle and uses it to call P3 (two-way transaction)
- P3 calls P2 (via magic handle 0) (two-way transaction)
- P2 calls P2 (via handle 1) (two-way transaction)
And then, if P2 does *NOT* accept the incoming transaction work, but
instead closes the binder fd, we get a crash.
Solve it by preventing the context manager from using ACQUIRE on ref 0.
There shouldn't be any legitimate reason for the context manager to do
that.
Additionally, print a warning if someone manages to find another way to
trigger a transaction-to-self bug in the future.

commit 16981742717b04644a41052570fb502682a315d2 upstream.
For BINDER_TYPE_PTR and BINDER_TYPE_FDA transactions, the
num_valid local was calculated incorrectly causing the
range check in binder_validate_ptr() to miss out-of-bounds
offsets.
Fixes: bde4a19fc04f ("binder: use userspace pointer as base of buffer space")

Bug: 145988638
Signed-off-by: Todd Kjos <tkjos@google.com>
There is a race between the binder driver cleaning
up a completed transaction via binder_free_transaction()
and a user calling binder_ioctl(BC_FREE_BUFFER) to
release a buffer. It doesn't matter which is first but
they need to be protected against running concurrently
which can result in a UAF.

commit f5cb779ba16334b45ba8946d6bfa6d9834d1527f upstream.
binder_poll() passes the thread->wait waitqueue that
can be slept on for work. When a thread that uses
epoll explicitly exits using BINDER_THREAD_EXIT,
the waitqueue is freed, but it is never removed
from the corresponding epoll data structure. When
the process subsequently exits, the epoll cleanup
code tries to access the waitlist, which results in
a use-after-free.
Prevent this by using POLLFREE when the thread exits.
