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,
