^^^^^^^^^
Fix same bug in `nft list tables'.
Don't cleanup the table object for these commands since it is NULL.

Rules with header fields that rely on the generic integer datatype
from sets are not matching, eg.
nft add rule filter input udp length { 9 } counter
This set member is an integer represented in host byte order, which
obviously doesn't match the header field (in network byte order).
Since the integer datatype has no specific byteorder, we have to rely
on the expression byteorder instead when configuring the context,
before we evaluate the list of set members.

The name of datatypes can be used in set definition so they should
follow the same logic (and maybe not contain space to avoid problem
with parsing).

If we add this rule:
nft add rule filter input meta length 33-55
the listing shows:
meta length >= 33 meta length <= 754974720
The two meta statements share the same left-hand side, thus, only the
first one is converted from network byte order to host byte order.
Update netlink_get_register() to return a clone so each left-hand side
has its own left-hand side.
Moreover, release the existing register before overriding it with fresh
expressions in netlink_set_register().
Thefore, if you manipulate a register from any of the existing parse
functions, you have to re-set it again to place fresh modified clone.

Current code is causing a failure in adding a set containing
a really long list of elements. The failure occurs as soon as
the line is longer than flex read buffer.
When a line is longer than scanner buffer size, the code in YY_INPUT
forces a rewind to the beginning of the string because it does not
find a end of line. The result is that the string is never parsed.
This patch updates the code by rewinding till we found a space.

Otherwise parsing with basetypes doesn't work. Now nft displays
an error when the symbolic constant is not correct:
<cmdline>:1:29-31: Error: Could not parse conntrack state
add rule test test ct state xxx accept
^^^
Use .sym_tbl instead and default on the symbol_constant_parse()
function from the ethertype and pkttype, this simplifies the code and
(more importantly) it avoids a breakage after the change in
integer_type_parse().

The following example:
# nft add rule filter input ct state 8 accept
Segmentation fault
leads to a crash because we have the following datatype relation:
ct_state -> bitmask -> integer
The bitmask, which is an intermediate basetype, has no parse()
function, this leads to a crash in symbolic_constant_parse().
Patrick suggested to walk down the chain until we find a parser
function.

If we use tcp reset with a network protocol that tcp is not supported,
we display an error. This error use the reject.expr location which is NULL,
therefore we have a crash. This patch replaces it using the reject statement
to display the error like:
Rule:

'nft' documentation is originally contained in the XML file 'doc/nft.xml'.
Processing this file with the proper tools we can obtain a PDF document,
'nft.pdf', and a unix man page, 'nft.8'.
To produce the PDF we need the tool 'dblatex' (current release
pypi.python.org/pypi/dblatex/0.3.5).
To produce the man page we use the tool 'docbook2man'; it is part of the
package 'docbook2X' (docbook2x.sourceforge.net). On some linux
distributions the tool can have slightly different names as 'docbook2x-man'
or 'db2x_docbook2man' so we search for all three names and use the first
one found and issue the command:
# ${DB2MAN} --xinclude $<

Moreover, this adds tests to the meta.t test file.

This patch changes the parser to permit both nat_flags and port specification
in the redirect expression.
The resulting syntax is:
% nft add rule nat prerouting redirect [port] [nat_flags]
The port specification requires a bit of context regardin the transport
protocol. Some examples:
% nft add rule nat prerouting tcp dport 22 redirect :23
% nft add rule add prerouting udp dport 53 redirect :5353
The nat_flags argument is the last argument:
% nft add rule nat prerouting tdp dport 80 redirect :8080 random
The port specification can be a range:
% nft add rule nat prerouting tcp dport 80 redirect :8080-8090 random
While at it, the regression tests files are updated.

This patch changes the default behaviour of nft to not translate IP
addresses to hostnames when printing rules if no options are passed.
The options regarding translations after this patch are:
<no -n/-N> show IP addresses numerically (default behaviour)
-n show IP addresses numerically
-nn show Internet services and uid/gid numerically
-nnn show protocols numerically
-N (--reversedns) translate IP addresses to names
The idea is to avoid breaking existing scripts that most likely rely on
'-n' to save the ruleset, so we reduce the impact of this patch and
provide a default behaviour that doesn't generate network traffic when
listing / saving the ruleset.
Joint work with Pablo.

In rules like:

or

we use icmpx to reject it. But if we have network context, we also use type of
reject. With this patch, we check the network context. If we don't have context,
we still use icmpx. However, if we have rules with network context like:

or

We are going to use icmp or icmpv6 to reject it taking into account the network

In Inet tables, we have to check the network context in rules that we use
icmp or icmpv6 reason in reject. To be sure that the context is the correct.
However, for icmpx and tcp reject, we don't need to check it.
In Bridge tables, ee have vlan and arp traffic and they are not supported.
For this things, we have to check the network context. For example:
nft add rule bridge test-bridge input \
ether type arp reject with icmp type host-unreachable
or
nft add rule bridge test-bridge input \
ether type vlan reject with tcp reset
In that cases, we have to throw an error. Moreover, we have to accept rules
that the network context is Ipv4 and Ipv6. For example:
nft add rule -nnn bridge test-bridge input \
ip protocol tcp reject with tcp reset
Moreover, this patch refactor the code for check the family for bridge and inet
tables.

If you add the rule:
nft add rule inet filter input reject with icmpx type host-unreachable
nft list table inet filter
shows:
table inet filter {
chain input {
reject with icmpx type 2
}
}
We have to attach the icmpx datatype when we list the rules that use it. With
this patch if we list the ruleset, the output is:
table inet filter {
chain input {
reject with icmpx type host-unreachable
}
}

If we use a rule:
nft add rule bridge filter input \
ether type ip reject with icmp type host-unreachable
or this:
nft add rule inet filter input \
meta nfproto ipv4 reject with icmp type host-unreachable
we have a segfault because we add a network dependency when we already have
network context.
