ipset 5 in an almost ready state - milestonev5.0-pre1
Reworked protocol and internal interfaces, missing set types added, backward compatibility verified, lots of tests added (and thanks to the tests, bugs fixed), even the manpage is rewritten ;-). Countless changes everywhere... The missing bits before announcing ipset 5: - net namespace support - new iptables/ip6tables extension library - iptables/ip6tables match and target tests (backward/forward compatibility) - tests on catching syntax errors

+\fBipset\fR
is used to set up, maintain and inspect so called IP sets in the Linux
-kernel. Depending on the type, an IP set may store IP addresses, (TCP/UDP)
-port numbers or additional informations besides IP addresses: the word IP
-means a general term here. See the set type definitions below.
-.P
-Iptables matches and targets referring to sets creates references, which
-protects the given sets in the kernel. A set cannot be removed (destroyed)
+kernel. Depending on the type of the set, an IP set may store IP(v4/v6)
+addresses, (TCP/UDP) port numbers, IP and MAC address pairs, IP address
+and port number pairs, etc. See the set type definitions below.
+.PP
+\fBIptables\fR
+matches and targets referring to sets creates references, which
+protect the given sets in the kernel. A set cannot be destroyed
while there is a single reference pointing to it.
-.SH OPTIONS
+.SH "OPTIONS"
The options that are recognized by
-.B ipset
+\fBipset\fR
can be divided into several different groups.
.SS COMMANDS
-These options specify the specific action to perform. Only one of them
-can be specified on the command line unless otherwise specified
-below. For all the long versions of the command and option names, you
-need to use only enough letters to ensure that
-.B ipset
-can differentiate it from all other options.
-.TP
-\fB\-N\fP, \fB\-\-create\fP \fIsetname\fP \fItype\fP \fItype-specific-options\fP
-Create a set identified with setname and specified type.
-Type-specific options must be supplied.
-.TP
-\fB\-X\fP, \fB\-\-destroy\fP [\fIsetname\fP]
+These options specify the desired action to perform. Only one of them
+can be specified on the command line unless otherwise specified below.
+For all the long versions of the command names, you need to use only enough
+letters to ensure that
+\fBipset\fR
+can differentiate it from all other options. The
+\fBipset\fR
+parser follows the order here when looking for the shortest match
+in the long command names.
+.TP
+\fBn\fP, \fBcreate\fP \fISETNAME\fP \fITYPENAME\fP [ \fICREATE\-OPTIONS\fP ]
+Create a set identified with setname and specified type. The type may require
+type specific options. If the
+\fB\-exist\fR
+option is specified,
+\fBipset\fR
+ignores the error otherwise raised when the the same set (setname and create parameters
+are identical) already exists.
+.TP
+\fBadd\fP \fISETNAME\fP \fIADD\-ENTRY\fP [ \fIADD\-OPTIONS\fP ]
+Add a given entry to the set. If the
+\fB\-exist\fR
+option is specified,
+\fBipset\fR
+ignores if the entry already added to the set.
+.TP
+\fBdel\fP \fISETNAME\fP \fIDEL\-ENTRY\fP [ \fIDEL\-OPTIONS\fP ]
+Delete an entry from a set. If the
+\fB\-exist\fR
+option is specified,
+\fBipset\fR
+ignores if the entry does not added (expired) to the set.
+.TP
+\fBtest\fP \fISETNAME\fP \fITEST\-ENTRY\fP [ \fITEST\-OPTIONS\fP ]
+Test wether an entry is in a set or not. Exit status number is zero
+if the tested entry is in the set and nonzero if it is missing from
+the set.
+.TP
+\fBx\fP, \fBdestroy\fP [ \fISETNAME\fP ]
Destroy the specified set or all the sets if none is given.
-If the set has got references, nothing is done.
-.TP
-\fB\-F\fP, \fB\-\-flush\fP [\fIsetname\fP]
-Delete all entries from the specified set or flush
-all sets if none is given.
-.TP
-\fB\-E\fP, \fB\-\-rename\fP \fIfrom-setname\fP \fIto-setname\fP
-Rename a set. Set identified by to-setname must not exist.
-.TP
-\fB\-W\fP, \fB\-\-swap\fP \fIfrom-setname\fP \fIto-setname\fP
-Swap the content of two sets, or in another words,
-exchange the name of two sets. The referred sets must exist and
-identical type of sets can be swapped only.
-.TP
-\fB\-L\fP, \fB\-\-list\fP [\fIsetname\fP]
-List the entries for the specified set, or for
+If the set has got reference(s), nothing is done and no set destroyed.
+.TP
+\fBlist\fP [ \fISETNAME\fP ]
+List the header data and the entries for the specified set, or for
all sets if none is given. The
-\fB\-r\fP/\fB\-\-resolve\fP
+\fB\-\-resolve\fP
option can be used to force name lookups (which may be slow). When the
-\fB\-s\fP/\fB\-\-sorted\fP
+\fB\-\-sorted\fP
option is given, the entries are listed sorted (if the given set
-type supports the operation).
-.TP
-\fB\-S\fP, \fB\-\-save\fP [\fIsetname\fP]
+type supports the operation). The option
+\fB\-\-output\fR
+can be used to control the format of the listing:
+\fBplain\fR, \fBsave\fR or \fBxml\fR.
+The default is
+\fBplain\fR.
+.TP
+\fBsave\fP [ \fISETNAME\fP ]
Save the given set, or all sets if none is given
-to stdout in a format that \fB\-\-restore\fP can read.
-.TP
-\fB\-R\fP, \fB\-\-restore\fP
-Restore a saved session generated by \fB\-\-save\fP. The saved session
-can be fed from stdin.
-
-When generating a session file please note that the supported commands
-(create set and add element) must appear in a strict order: first create
-the set, then add all elements. Then create the next set, add all its elements
-and so on. Also, it is a restore operation, so the sets being restored must
-not exist.
-.TP
-\fB\-A\fP, \fB\-\-add\fP \fIsetname\fP \fIentry\fP
-Add an entry to a set.

-\fB\-D\fP, \fB\-\-del\fP \fIsetname\fP \fIentry\fP

-.SH SET TYPES
-ipset supports the following set types:
-.SS ipmap
-The ipmap set type uses a memory range, where each bit represents
-one IP address. An ipmap set can store up to 65536 (B-class network)
-IP addresses. The ipmap set type is very fast and memory cheap, great
-for use when one want to match certain IPs in a range. If the optional
-\fB\-\-netmask\fP
-parameter is specified with a CIDR netmask value between 1-31 then
-network addresses are stored in the given set: i.e an
-IP address will be in the set if the network address, which is resulted
-by masking the address with the specified netmask, can be found in the set.

-.SS iphash
-The iphash set type uses a hash to store IP addresses.
-In order to avoid clashes in the hash double-hashing, and as a last
-resort, dynamic growing of the hash performed. The iphash set type is
-great to store random addresses. If the optional
-\fB\-\-netmask\fP

-network addresses are stored in the given set: i.e an
-IP address will be in the set if the network address, which is resulted

-produces larger, sparser hash.
-.PP
-Example:

+.SH "SET TYPES"
+A set type comprises of the storage method by which the data is stored and
+the data type(s) which are stored in the set. Therefore the
+\fITYPENAME\fR
+parameter of the
+\fBcreate\fR
+command follows the syntax
+
+\fITYPENAME\fR := \fImethod\fR\fB:\fR\fItype\fR[\fB,\fR\fItype\fR[\fB,\fR\fItype\fR]]
+
+where the current list of the methods are
+\fBbitmap\fR, \fBhash\fR, \fBlist\fR and the possible data types are \fBip\fR,
+\fBmac\fR and \fBport\fR.
+
+When adding, deleting or testing entries in a set, the same comma separated
+data syntax must be used for the entry parameter of the commands, i.e
+
+ipset add foo ipaddr,portnum,ipaddr
+
+All set types support the optional
+
+\fBtimeout\fR \fIvalue\fR
+
+parameter when creating a set and adding entries. The value of the \fBtimeout\fR
+parameter for the \fBcreate\fR command means the default timeout value (in seconds)
+for new entries. If a set is created with timeout support, then the same
+\fBtimeout\fR option can be used to specify non\-default timeout values
+when adding entries. Zero timeout value means the entry is added permanent to the set.
+.SS bitmap:ip
