Add a start of a man-page to the misc section as a reference and
guide on (e)BPF classifier and actions. Given that tc is only tersely
documented, this is provided in the hope that users will have an
easier getting started with tc and (e)BPF. And, that there's now more
incentive for others to also start documenting their classifier and
actions as well. ;)

This patch fixes incorrect -EINVAL errors due to invalid
scope and type during mpls route deletes.

$ip -f mpls route add 100 as 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1
RTNETLINK answers: Invalid argument

$ip -f mpls route del 100
RTNETLINK answers: Invalid argument

After patch:

$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1

$ip -f mpls route show

Always set type to RTN_UNICAST for mpls route add/deletes.
Also to keep things consistent with kernel set scope to
RT_SCOPE_UNIVERSE for both mpls and ipv6 routes. Both mpls and ipv6 route
deletes ignore scope.

Kernel commit 04fd61ab36ec ("bpf: allow bpf programs to tail-call other
bpf programs") added support for tail calls, this patch here adds tc
front end parts for the object parser to prepopulate a given eBPF prog
array before the root prog is pushed down for classifier creation. The
prepopulation works with any number of prog arrays in any dependencies,
e.g. prog or normal maps could also be used from progs that are
tail-called themself, etc.

Don't echo "-e" when using builtin echo in bash.

s->local.data is a pointer to a field of a non-NULL struct, and hence
cannot be NULL, thus comparing it to 0 is always false, and thus the
return is always false.

Presumably this was meant to be a check whether s->local.data[0] (which
I believe stores af_packet protocol) is 0, ie. ANY.

The initializers are simply not needed.

These if-blocks are outright dead code, because '0 > unsigned' is always
false, so only else clause triggers and regardless of which clause triggers
it only updates 'ind' which is later unconditionally written to before
being used anyway.

Otherwise we get errors from clang:

If a tunnel is created with a local address, you can't change it to any.

 # ip tunnel add tunl1 mode ipip remote 10.16.42.37 local 10.16.42.214 ttl 64
 # ip tunnel show tunl1
 tunl1: ip/ip  remote 10.16.42.37  local 10.16.42.214  ttl 64
 # ip tunnel change tunl1 local any
 # echo $?
 0
 # ip tunnel show tunl1
 tunl1: ip/ip  remote 10.16.42.37  local 10.16.42.214  ttl 64

It happens that parse_args zeroes ip_tunnel_parm, and when creating the
tunnel, it is OK to leave it as is if the address is any. However, when
changing the tunnel, the current parameters will be read from
ip_tunnel_parm, and local and remote address won't be zeroes anymore, so
it needs to be explicitly set to any.

ss currently dumps IPv4 sockets, then IPv6 sockets from the kernel,
even if -4 or -6 option was given. Filtering in user space then has to
drop all sockets of wrong family. Such a waste of time...

I doubt TCP_CA_NAME_MAX will ever change in the kernel : 16 bytes.

Its typically "cubic" and less than 8 bytes.

Using 8 bytes to point to a malloc(8) is a waste.

Please remove the memory allocation, or store the pointer, since
tcp_show_info() does the malloc()/free() before return.

Indicate existence of libmnl which is required by tipc.

Make sure we use 64-bit filesystem functions everywhere.  This applies not
only to being able to read large files (which generally doesn't apply to
