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.

Eugene Syromiatnikov (2):
  bpf_trace: check size for overflow in bpf_kprobe_multi_link_attach
  bpf_trace: bail out from bpf_kprobe_multi_link_attach when in compat
