From: Roberto Sassu Sent: Tuesday, June 28, 2022 2:28 PM Ensure that signature verification is performed successfully from an eBPF program, with the new bpf_verify_pkcs7_signature() helper. Generate a testing signature key and compile sign-file from scripts/, so that the test is selfcontained. Also, search for the tcb_bic.ko kernel module, parse it in user space to extract the raw PKCS#7 signature and send it to the eBPF program for signature verification. If tcb_bic.ko is not found, the test does not fail.
Ops, tcp_bic.ko. Roberto
