Hi Greg,
if you have a chance, please queue the following BPF patches for -stable:
Always cc: stable@vger for stable stuff, as I'm not the only stable tree
out there...
...

4.17.y:
3a38bb98d9ab ("bpf/tracing: fix a deadlock in perf_event_detach_bpf_prog")

This is already in 4.17.
...
c93552c443eb ("bpf: properly enforce index mask to prevent out-of-bounds speculation")

So is this.
...
58990d1ff3f7 ("bpf: reject passing modified ctx to helper functions")

Now applied.
...
b16558579576 ("bpf: implement dummy fops for bpf objects")

Does not apply at all :(
...
7d1982b4e335 ("bpf: fix panic in prog load calls cleanup")

Does not apply :(
...
ed2b82c03dc1 ("bpf: hash map: decrement counter on error")

This is not in Linus's tree.
...

4.14.y:
c93552c443eb ("bpf: properly enforce index mask to prevent out-of-bounds speculation")

Doesn't apply to 4.14.y :(
...
b16558579576 ("bpf: implement dummy fops for bpf objects")

Does not apply at all.
...
ed2b82c03dc1 ("bpf: hash map: decrement counter on error")

Not in Linus's tree.
Can you send me the needed backports?
thanks,
greg k-h
