SkbeditAction

The SkbeditAction class supports SKB editing.

class SkbeditAction(action_index: Optional[int] = None, decision: Optional[ActionDecision] = None, *, queue_mapping: Optional[int] = None, priority: Optional[str] = None, mark: Optional[int] = None, mask: Optional[int] = None, packet_type: Optional[str] = None, inheritdsfield: Optional[bool] = False)[source]

This class supports the tc(8) skbedit action as documented in tc-skbedit(8).

Parameters:

  • action_index – an integer that effectively names the action

  • decision – control action to take

  • queue_mapping – specify transmit queue for packet

  • priority – priority

  • mark – firewall mark

  • mask – mask for the mark

  • packet_type – packet type

  • inheritdsfield – use the DiffServ field to override the classification decision

classmethod get_kind() → str[source]

Returns skbedit

get_queue_mapping() → Optional[int][source]

Returns the queue mapping, if any

get_priority() → Optional[str][source]

Returns the priority, if any

get_mark() → Optional[int][source]

Returns the firewall mark, if any

get_mask() → Optional[int][source]

Returns the mask for the firewall mark, if any

get_packet_type() → Optional[str][source]

Returns the packet type, if any

inheritdsfield() → bool[source]

Returns the inheritdsfield value

action_creation_args() → List[str]

Returns a list of tc(8) arguments to instantiate this action

get_action_index() → Optional[int]

Returns the action index

get_decision() → Optional[ActionDecision]

Returns the decision (e.g. ActionDecision.DROP) for this action

get_install_duration() → int

Returns the number of seconds since the action was installed (created)

get_stats() → Optional[ActionStats]

Returns action statistics

get_use_duration() → int

It is not clear how the use duration (in seconds) is defined. As a data point, the install duration and use duration of an action created as part of a filter creation always have the same value.

parse_common_lines(line_iter: LineGroupIterator) → None

Parse lines common to all actions. Stop when an empty line is encountered (the end of the action)

set_action_index(action_index: int) → None

Sets the action index

set_durations(*, install_duration: int, use_duration: int) → None

Set the install and use duration
