glibc added support for DT_GNU_HASH in 2006 and DT_HASH has been
obsoleted for more than one decade in many Linux distributions.
Many vDSOs support DT_GNU_HASH. This patch adds selftests support.

Test that nullness elision works for common use cases. For example, we
want to check that both full and subreg stack slots recognized. As well
as multiple lookups. And obviously some bound checks.

This patch allows progs to elide a null check on statically known map
lookup keys. In other words, if the verifier can statically prove that
the lookup will be in-bounds, allow the prog to drop the null check.
This is useful for two reasons:
1. Large numbers of nullness checks (especially when th

The error message describing the required modules is inaccurate.
Currently, only "SKIP: Need act_mirred module" is printed when any of
the modules are missing. As a result, users might only include that

when TCP over IPv4 via INET6 API, bpf_get/setsockopt with ipv4 will
fail, because sk->sk_family is AF_INET6. With ipv6 will success, not
take effect, because inet_csk(sk)->icsk_af_ops is ipv6_mapped and

From: Feng Zhou
When TCP over IPv4 via INET6 API, sk->sk_family is AF_INET6, but it is a v4 pkt.
inet_csk(sk)->icsk_af_ops is ipv6_mapped and use ip_queue_xmit. Some sockopt did
not take effect, such as tos.
0001: Use sk_is_inet helper to fix it.
0002: Setget_sockopt add a test for tcp over ipv4
Ksym addr access is restricted
by ``kptr_restrict``(/proc/sys/kernel/kptr_restrict).
On some OS systems(like Android),
ksym addr access is not accessed because ``kptr_restrict=2`.
And it took me a long time to find the root case.
-When ``kptr_restrict==0``, addr is accessed.
