This patch implements the core logic for BPF CO-RE offsets relocations.

Since node internal messages are passed directly to the socket, it is not
possible to observe those messages via tcpdump or wireshark.
We now remedy this by making it possible to clone such messages and send
the clones to the loopback interface. The clones are dropped at r

Some time back supported was added for devlink 'resources'. The idea is
that hardware (mlxsw) has limited resources (e.g., memory) that can be
allocated in certain ways (e.g., kvd for mlxsw) thus implementing
restrictions on the number of programmable entries (e.g., routes,
neighbors) by userspace.

mlx5e_grp_q_update_stats seems to be using the wrong counter

as I mentioned on the phone, any outcome of that thread will be in 5.4
at best. Meanwhile this breakage in 5.2 and 5.3 needs to be fixed.

Hi,
How do I request back-porting of commit 5b18f1289808 ("ipv4: reset
rt_iif for recirculated mcast/bcast out pkts") quoted below? I think for
4.19, the following diff is needed in addition to the commit:
diff --git a/net/ipv4/route.c b/net/ipv4/route.c

Now that test__printf is a simple wraper around printf, let's drop it
(and test__vprintf as well).

I was looking into converting test_sockops* to test_progs framework
and that requires using cgroup_helpers.c which rely on stdio/stderr.
Let's use open_memstream to override stdout into buffer during
subtests instead of custom test_{v,}printf wrappers. That lets
us continue to use stdio in the subt

Use open_memstream to override stdout during test execution.
The copy of the original stdout is held in env.stdout and used
to print subtest info and dump failed log.
test_{v,}printf are now simple wrappers around stdout and will be
removed in the next patch.
