Add the userspace control portion of the backported kernelspace
act_ctinfo.
ctinfo is a tc action restoring data stored in conntrack marks to
various fields. At present it has two independent modes of operation,
restoration of DSCP into IPv4/v6 diffserv and restoration of conntrack
marks into packet skb marks.
It understands a number of parameters specific to this action in
additional to the usual action syntax. Each operating mode is
independent of the other so all options are optional, however not
specifying at least one mode is a bit pointless.
Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
[CONTROL] [index <INDEX>]
DSCP mode
dscp enables copying of a DSCP stored in the conntrack mark into the
ipv4/v6 diffserv field. The mask is a 32bit field and specifies where
in the conntrack mark the DSCP value is located. It must be 6
contiguous bits long. eg. 0xfc000000 would restore the DSCP from the
upper 6 bits of the conntrack mark.
The DSCP copying may be optionally controlled by a statemask. The
statemask is a 32bit field, usually with a single bit set and must not
overlap the dscp mask. The DSCP restore operation will only take place
if the corresponding bit/s in conntrack mark ANDed with the statemask
yield a non zero result.
eg. dscp 0xfc000000 0x01000000 would retrieve the DSCP from the top 6
bits, whilst using bit 25 as a flag to do so. Bit 26 is unused in this
example.
CPMARK mode
cpmark enables copying of the conntrack mark to the packet skb mark. In
this mode it is completely equivalent to the existing act_connmark
action. Additional functionality is provided by the optional mask
parameter, whereby the stored conntrack mark is logically ANDed with the
cpmark mask before being stored into skb mark. This allows shared usage
of the conntrack mark between applications.
eg. cpmark 0x00ffffff would restore only the lower 24 bits of the
conntrack mark, thus may be useful in the event that the upper 8 bits
are used by the DSCP function.
Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
[CONTROL] [index <INDEX>]
where :
dscp MASK is the bitmask to restore DSCP
STATEMASK is the bitmask to determine conditional restoring
cpmark MASK mask applied to restored packet mark
ZONE is the conntrack zone
CONTROL := reclassify | pipe | drop | continue | ok |

Compile-based feature detection (e.g. xtables, ipset support) was broken
due to silent compilation errors in the configure script, caused by a

as used for the iptables build.
Remove redundant or unused Build/Configure definitions from package

Don't pass LDFLAGS within MAKE_FLAGS as this interferes with LDFLAGS in
tc/Makefile and masks a link parameter ("-Wl,-export-dynamic"). Instead,

The iproute2 build system links libelf support to every utility while only
the tc program actually requires libelf specific functionality.
Unfortunately the BPF ELF functionality is not confined into an own
compilation unit but added to the existing bpf.c sources of the shared
static libutil.a, causing every iproute2 applet to pick up an implicit
libelf.so dependency.
In order to avoid this requirement, patch the iproute2 build system to
create both a libutil.a and a libutil-elf.a, with the former being built
without libelf functionality and to only link the tc applet with the libelf
enabled libutil.
Finally, make the tc package depend on libelf to solve compilation errors.

Backport this canonical support from upstream into iproute2 v4.17
There is no kernel kmod/userspace tc ABI change in this release from the

option 'autorate_ingress' has been changed to 'autorate-ingress' to fit
in with upstream option naming expectations.

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
print_uint() will silently promote its variable type to uint64_t, but there
is nothing that ensures that the format string specifier passed along with
it fits (and the function name suggest to pass "%u").
Fix this by changing print_uint() to use a native 'unsigned int' type, and
introduce a separate print_u64() function for printing 64-bit values. All
call sites that were actually printing 64-bit values using print_uint() are
converted to use print_u64() instead.
Since print_int() was already using native int types, just add a
print_s64() to match, but don't convert any call sites.

Cake in kernel space now splits stats structure handling across netlink
messages to reduce stack usage issue flagged by upstream kernel checks.
Update user space (tc) qdisc handling to understand this new regime.
Cake also reports packet overheads & compensation in a different way so
add display code for this. e.g.
'tc -s qdisc show dev eth0' reports this extra detail:
min/max transport layer size: 28 / 1500
min/max overhead-adjusted size: 65 / 1550
average transport hdr offset: 14
Cake also supports output in JSON format.

print_int used 'int' type internally, whereas print_uint used 'uint64_t'
These helper functions eventually call vfprintf(fp, fmt, args) which is
a variable argument list function and is dependent upon 'fmt' containing
correct information about the length of the passed arguments.
Unfortunately print_int v print_uint offered no clue to the programmer
that internally passed ints to print_uint were being promoted to 64bits,
thus the format passed in 'fmt' string vs the actual passed integer
could be different lengths. This is even more interesting on big endian
architectures where 'vfprintf' would be looking in the middle of an
int64 type. Symptoms of this included tc qdisc showing bizarre values
for a variety of fields across a variety of qdiscs (e.g. refcnt, flows,
quantum)
print_u/int now stick with native int size.

There has been recent significant activity with the cake qdisc of late
Some of that effort is related to upstreaming to kernel & iproute2
mainline but we're not quite there yet. This commit teaches tc how to
activate and interprete the latest cake operating modes, namely:
ingress mode: Instead of only counting packets that make it past the
shaper, include packets we've decided to drop as well, since they did
arrive with us on the link and took link capacity.
This mode is more suitable for shaping the ingress of a link
(e.g. from ISP) rather than the more normal egress.
ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in
highly assymetric links (downstream v upstream capacity) where the
majority of upstream link capacity is occupied with ACKS for downstream
traffic.
