Subject: [PATCH] lib: split parser from command execution
ipset_parse_argv() parses, builds and send the netlink messages to the
kernel. This patch extracts the parser and wrap it around the new
ipset_parser() function.
This patch comes is preparation for the ipset to nftables translation
infrastructure.

Subject: [PATCH] lib: Detach restore routine from parser
Do not call restore() from ipset_parser(). Instead, ipset_parser()
returns the IPSET_CMD_RESTORE command and the caller invokes restore().
This patch comes in preparation for the ipset to nftables translation
infrastructure.

Subject: [PATCH] add ipset to nftables translation infrastructure
This patch provides the ipset-translate utility which allows you to
translate your existing ipset file to nftables.
The ipset-translate utility is actually a symlink to ipset, which checks
for 'argv[0] == ipset-translate' to exercise the translation path.
You can translate your ipset file through:
ipset-translate restore < sets.ipt
This patch reuses the existing parser and API to represent the sets and
the elements.
There is a new ipset_xlate_set dummy object that allows to store a
created set to fetch the type without interactions with the kernel.

+.TH IPSET-TRANSLATE 8 "May 31, 2021"
+
+.SH NAME
+ipset-translate \(em translation tool to migrate from ipset to nftables
+.SH DESCRIPTION
+This tool allows system administrators to translate a given IP sets file
+to \fBnftables(8)\fP.
+
+The only available command is:
+
+.IP \[bu] 2
+ipset-translate restores < file.ipt
+
+.SH USAGE
+The \fBipset-translate\fP tool reads an IP sets file in the syntax produced by
+\fBipset(8)\fP save. No set modifications occur, this tool is a text converter.
+
+.SH EXAMPLES
+Basic operation examples.
+
+Single command translation, assuming the original file:
+
+.nf
+create test1 hash:ip,port family inet counters timeout 300 hashsize 1024 maxelem 65536 bucketsize 12 initval 0xb5c4be5d
+add test1 1.1.1.1,udp:20
+add test1 1.1.1.1,21
+create test2 hash:ip,port family inet hashsize 1024 maxelem 65536 bucketsize 12 initval 0xb5c4be5d
+.fi
+
+which results in the following translation:
+
+.nf
+root@machine:~# ipset-translate restore < file.ipt
+add set inet global test1 { type ipv4_addr . inet_proto . inet_service; counter; timeout 300s; size 65536; }
+add element inet global test1 { 1.1.1.1 . udp . 20 }
+add element inet global test1 { 1.1.1.1 . tcp . 21 }
+add set inet global test2 { type ipv4_addr . inet_proto . inet_service; size 65536; }
+.fi
+
+.SH LIMITATIONS
+A few IP sets options may be not supported because they are not yet implemented
+in \fBnftables(8)\fP.
+
+Contrary to \fBnftables(8)\fP, IP sets are not attached to a specific table.
+The translation utility assumes that sets are created in a table whose name
+is \fBglobal\fP and family is \fBinet\fP. You might want to update the
+resulting translation to use a different table name and family for your sets.
+
+To get up-to-date information about this, please head to
+\fBhttps://wiki.nftables.org/\fP.
+

Subject: [PATCH] tests: add tests ipset to nftables
This test checks that the translation from ipset to nftables is correct.
term$ cd tests/xlate
term$ ./runtest.sh
in case that the translation is not correct, it shows the diff with expected
translation output.

Subject: [PATCH] Fix IPv6 sets nftables translation
The parser assumes the set is an IPv4 ipset because IPSET_OPT_FAMILY is
not set.
# ipset-translate restore < ./ipset-mwan3_set_connected_ipv6.dump
add table inet global
add set inet global mwan3_connected_v6 { type ipv6_addr; flags interval; }
flush set inet global mwan3_connected_v6
ipset v7.15: Error in line 4: Syntax error: '64' is out of range 0-32
Remove ipset_xlate_type_get(), call ipset_xlate_set_get() instead to
obtain the set type and family.
Reported-by: Florian Eckert <fe@dev.tdt.de>

Subject: [PATCH] ipset-translate: allow invoking with a path name
Executing /usr/sbin/ipset-translate results in the ipset functionality being run, rather than the ipset-translate functionality.
# ipset-translate destroy fred
This command is not supported, use `ipset-translate restore < file'
# /usr/sbin/ipset-translate destroy fred
ipset v7.15: The set with the given name does not exist
use basename() to resolve the issue.
