[LTP] [PATCH 1/1] bpf_prog0[5-7]: Run with kernel.unprivileged_bpf_disabled = 0

[Petr Vorel]

To avoid forcing users to run this setup to avoid TCONF:

tst_capability.c:29: TINFO: Dropping CAP_BPF(39)
bpf_common.c:39: TCONF: Hint: check also /proc/sys/kernel/unprivileged_bpf_disabled
bpf_common.c:41: TCONF: bpf() requires CAP_SYS_ADMIN or CAP_BPF on this system: EPERM (1)

Unfortunately this requires running as root.
