Subject: HELP: bpf_probe_user_write for registers
Date: Sun, 29 Nov 2020 19:34:14 +0100	[thread overview]
Message-ID: <eea9673f-5ee4-4adc-bc64-fcc88f715cc8@www.fastmail.com> (raw)

Hi,

I've been looking into introspecting and possibly convincing an application to behave slightly different with bpf measures.

I found `bpf_probe_user_write` but as far as I can tell, that only works for memory areas. 
Is there an alternative that can be used on registers as well?

Thanks,
ongy
