It looks like all necessary commits for CVE-2020-29373 are there on the
5.6 kernel.
I am investigating if this is caused by missing commit
dd821e0c95a64b5923a0c57f07d3f7563553e756 ("io_uring: fix missing
msg_name assignment").

Bug description:
io_uring02 from ubuntu_ltp_syscalls fails on F/oem-5.6 5.6.0-1056.60
on host spitfire
This test isn't found to be ran on previous versions on F/oem-5.6, so
would not consider this to be a regression.
