4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Martijn Coenen <maco@android.com>
commit 5cdcf4c6a638591ec0e98c57404a19e7f9997567 upstream.
binder_fd_array_object starts with a 4-byte header,
followed by a few fields that are 8 bytes when
ANDROID_BINDER_IPC_32BIT=N.
This can cause alignment issues in a 64-bit kernel
with a 32-bit userspace, as on x86_32 an 8-byte primitive
may be aligned to a 4-byte address. Pad with a __u32
to fix this.
