Subject: [Bug 199823] New: HTB not honoring Queue priority when being
overdriven with large limits
https://bugzilla.kernel.org/show_bu
Static key is used to enable/disable cgroup-bpf related code paths at
run time.
Though it's not defined when cgroup-bpf is disabled at compile time,
i.e. CONFIG_CGROUP_BPF=n, and if some code wants to use it, it has to do
this:
#ifdef CONFIG_CGROUP_BPF
if (cgroup_bpf_enabl
libbpf can guess prog type and expected attach type based on section
name. Add hints for "cgroup/sendmsg4" and "cgroup/sendmsg6" section
names.

Add selftest for BPF_CGROUP_UDP4_SENDMSG and BPF_CGROUP_UDP6_SENDMSG
attach types.
Try to sendmsg(2) to specific IP:port and test that:
* source IP is overridden as expected.
* remote IP:port pair is overridden as expected;
Both UDPv4 and UDPv6 are tested.
Output:
# test_sock_addr.sh 2>/dev/nu
v3 -> v4:
* handle static key correctly for CONFIG_CGROUP_BPF=n.
v2 -> v3:
* place BPF logic under static key in udp_sendmsg, udpv6_sendmsg;
* rebase.
v1 -> v2:
* return ENOTSUPP if bpf_prog rewrote IPv6-only with IPv4-mapped IPv6;
* add test for IPv4-mapped IPv6 use-case;
* fix build for CONFIG_
Sync new `BPF_CGROUP_UDP4_SENDMSG` and `BPF_CGROUP_UDP6_SENDMSG`
attach types to tools/.

test_sock_addr was not easy to extend since it was focused on sys_bind
and sys_connect quite a bit.
Reorganized it so that it'll be easier to cover new test-cases for
`BPF_PROG_TYPE_CGROUP_SOCK_ADDR`:
- decouple test-cases so that only one BPF prog is tested at a time;
- check programmatically t
In addition to already existing BPF hooks for sys_bind and sys_connect,
the patch provides new hooks for sys_sendmsg.
It leverages existing BPF program type `BPF_PROG_TYPE_CGROUP_SOCK_ADDR`
that provides access to socket itlself (properties like family, type,
protocol) and user-passed `struct sock
