Describe the bug
https://github.com/amazonlinux/linux/commit/b022f0c7e404887a7c5229788fc99eff9f9a80d5 introduced a bug which made it impossible to attach a kprobe to a kernel module function, returning ENOENT. This was subsequently fixed a week later in https://github.com/amazonlinux/linux/commit/926fe783c8a64b33997fec405cf1af3e61aed441 but this commit has not been back-ported to Amazon Linux 2023.
ENOENT
To Reproduce Steps to reproduce the behavior:
Attach a kprobe to a kernel module function, such as __nf_conntrack_hash_insert in the nf_conntrack kernel module. You get the same error regardless if you get use the PMU or tracefs methods of attaching.
__nf_conntrack_hash_insert
nf_conntrack
Expected behavior
Successful kprobe attach.
Additional context
uname -r = 6.1.61-85.141.amzn2023.x86_64
