Hello. While [1] seems to require additional work[2] due to changes in the interface (and it has already been re-targeted for bpf-next), I would like to ask to consider the following two patches, that fix possible out-of-bounds write and properly disable the interface for 32-bit compat user space, for the 5.18 release. Thank you.
