-Subject: [PATCH] tc: add support for action act_ctinfo
|
|
|
-MIME-Version: 1.0

-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 |
|
|
|
- goto chain <CHAIN_INDEX>

|
|
|
-+.SH DESCRIPTION
|
|
|
-+CTINFO (Conntrack Information) is a tc action for retrieving data from
|
|
|
-+conntrack marks into various fields. At present it has two independent
|
|
|
-+processing modes which may be viewed as sub-functions.
|
|
|
-+
|
|
|
-+DSCP mode copies a DSCP stored in conntrack's connmark into the IPv4/v6 diffserv
|
|
|
-+field. The copying may conditionally occur based on a flag also stored in the
|
|
|
-+connmark. DSCP mode was designed to assist in restoring packet classifications on
|
|
|
-+ingress, classifications which may then be used by qdiscs such as CAKE. It may be
|
|
|
-+used in any circumstance where ingress classification needs to be maintained across
|
|
|
-+links that otherwise bleach or remap according to their own policies.
|
|
|
-+
|
|
|
-+CPMARK (copymark) mode copies the conntrack connmark into the packet's mark field. Without
|
|
|
-+additional parameters it is functionally completely equivalent to the existing
|
|
|
-+connmark action. An optional mask may be specified to mask which bits of the
|
|
|
-+connmark are restored. This may be useful when DSCP and CPMARK modes are combined.
|
|
|
-+
|
|
|
-+Simple statistics (tc -s) on DSCP restores and CPMARK copies are maintained where values for
|
|
|
-+set indicate a count of packets altered for that mode. DSCP includes an error count
|
|
|
-+where the destination packet's diffserv field was unwriteable.
|
|
|
-+.SH PARAMETERS
|
|
|
-+.SS DSCP mode parameters:
|
|
|
-+.IP mask
|
|
|
-+A mask of 6 contiguous bits indicating where the DSCP value is located in the 32 bit
|
|
|
-+conntrack mark field. A mask must be provided for this mode. mask is a 32 bit
|
|
|
-+unsigned value.
|
|
|
-+.IP statemask
|
|
|
-+A mask of at least 1 bit indicating where a conditional restore flag is located in the
|
|
|
-+32 bit conntrack mark field. The statemask bit/s must NOT overlap the mask bits. The
|
|
|
-+DSCP will be restored if the conntrack mark logically ANDed with the statemask yields
|
|
|
-+a non-zero result. statemask is an optional unsigned 32 bit value.
|
|
|
-+.SS CPMARK mode parameters:
|
|
|
-+.IP mask
|
|
|
-+Store the logically ANDed result of conntrack mark and mask into the packet's mark
|
|
|
-+field. Default is 0xffffffff i.e. the whole mark field. mask is an optional unsigned 32 bit
|
|
|
-+value
|
|
|
-+.SS Overall action parameters:
|
|
|
-+.IP zone
|
|
|
-+Specify the conntrack zone when doing conntrack lookups for packets.
|
|
|
-+zone is a 16bit unsigned decimal value.
|
|
|
-+Default is 0.
|
|
|
-+.IP CONTROL

|
|
|
-+filters and actions is further traversed after this action.

|
|
|
-+.B drop

|
|
-+Drop the packet.

|
|

|
|
|
-+Continue classification with the next filter in line.
|
|
|
-+.TP
|
|
|
-+.B pass
|
|
|
-+Finish classification process and return to calling qdisc for further packet
|
|
|
-+processing. This is the default.
|
|
|
-+.RE
|
|
|
-+.IP index
|
|
|
-+Specify an index for this action in order to being able to identify it in later
|
|
|
-+commands. index is a 32bit unsigned decimal value.
