f8615bf8a3 netfilter: ipset: move ip_set_get_ip_port() to ip_set_bitmap_port.c.
ip_set_get_ip_port() is only used in ip_set_bitmap_port.c.  Move it
there and make it static.

856391854c netfilter: ipset: make ip_set_put_flags extern.
ip_set_put_flags is rather large for a static inline function in a

94177f6e11 netfilter: ipset: move ip_set_comment functions from ip_set.h to ip_set_core.c.
Most of the functions are only called from within ip_set_core.c.

The exception is ip_set_init_comment.  However, this is too complex to
be a good candidate for a static inline function.  Move it to
ip_set_core.c, change its linkage to extern and export it, leaving a
declaration in ip_set.h.

ip_set_comment_free is only used as an extension destructor, so change
its prototype to match and drop cast.

f19438bdd4 netfilter: remove CONFIG_NETFILTER checks from headers.
`struct nf_hook_ops`, `struct nf_hook_state` and the `nf_hookfn`
function typedef appear in function and struct declarations and
definitions in a number of netfilter headers.  The structs and typedef
themselves are defined by linux/netfilter.h but only when
CONFIG_NETFILTER is enabled.  Define them unconditionally and add
forward declarations in order to remove CONFIG_NETFILTER conditionals
from the other headers.

Move some `struct nf_conntrack` code from linux/skbuff.h to

getting and setting skb->_nfct, it allows us to remove

Several header-files, Kconfig files and Makefiles have trailing
white-space.  Remove it.

In netfilter/Kconfig, indent the type of CONFIG_NETFILTER_NETLINK_ACCT
correctly.

There are semicolons at the end of two function definitions in
include/net/netfilter/nf_conntrack_acct.h and
include/net/netfilter/nf_conntrack_ecache.h. Remove them.

bd96b4c756 netfilter: inline four headers files into another one.
linux/netfilter/ipset/ip_set.h included four other header files:

  include/linux/netfilter/ipset/ip_set_comment.h
  include/linux/netfilter/ipset/ip_set_counter.h
  include/linux/netfilter/ipset/ip_set_skbinfo.h
  include/linux/netfilter/ipset/ip_set_timeout.h

Of these the first three were not included anywhere else.  The last,
ip_set_timeout.h, was included in a couple of other places, but defined
inline functions which call other inline functions defined in ip_set.h,
so ip_set.h had to be included before it.

Inlined all four into ip_set.h, and updated the other files that
included ip_set_timeout.h.

05ba4c8953 netfilter: Update obsolete comments referring to ip_conntrack
In 9fb9cbb108 ("[NETFILTER]: Add nf_conntrack subsystem.") the new
generic nf_conntrack was introduced, and it came to supersede the old
ip_conntrack.

This change updates (some) of the obsolete comments referring to old
file/function names of the ip_conntrack mechanism, as well as removes a
few self-referencing comments that we shouldn't maintain anymore.

I did not update any comments referring to historical actions (e.g,
comments like "this file was derived from ..." were left untouched, even
if the referenced file is no longer here).

ae0be8de9a netlink: make nla_nest_start() add NLA_F_NESTED flag
Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most
netlink based interfaces (including recently added ones) are still not
setting it in kernel generated messages. Without the flag, message parsers
not aware of attribute semantics (e.g. wireshark dissector or libmnl's
mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display
the structure of their contents.

Unfortunately we cannot just add the flag everywhere as there may be
userspace applications which check nlattr::nla_type directly rather than
through a helper masking out the flags. Therefore the patch renames
nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start()
as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually
are rewritten to use nla_nest_start().

Except for changes in include/net/netlink.h, the patch was generated using
this semantic patch:

@@ expression E1, E2; @@
-nla_nest_start(E1, E2)
+nla_nest_start_noflag(E1, E2)

@@ expression E1, E2; @@
-nla_nest_start_noflag(E1, E2 | NLA_F_NESTED)
+nla_nest_start(E1, E2)
