Revision 1292e972fff2b2d81e139e0c2fe5f50249e78c58 authored by Eugene Syromiatnikov on 15 January 2020, 16:35:38 UTC, committed by Jens Axboe on 21 January 2020, 00:00:44 UTC
fds field of struct io_uring_files_update is problematic with regards to compat user space, as pointer size is different in 32-bit, 32-on-64-bit, and 64-bit user space. In order to avoid custom handling of compat in the syscall implementation, make fds __u64 and use u64_to_user_ptr in order to retrieve it. Also, align the field naturally and check that no garbage is passed there.
