This dict will always be the same, given the same input, so we can ``@lru_cache()`` it. n.b.: ``@lru_cache()`` takes only the ``__hash__()`` of the input (``text``), so it should be fairly quick, despite our giant inputs. @param text: The output of ``ifconfig -a`` @returns: A dict of ``Ifstate``s, referenced by ``name`` and ``mac`` r )� � � �:N���zflags=r r r r z capabilities=�<|>r z description:� zoptions=�ec_capabilities� ec_enabled�,�ether�hwaddrzgroups:zmedia:z: r r r r zmember:z laggport:zvlan:�idz interface:�link)'r �list� splitlines�len�split�endswithr r r? �lower�strip� startswith� _parse_flags�copy�deepcopyr r r r �re�append�intr r r r r r r r � _parse_inetr � _parse_inet6r r r �range�dictr@ )r rA �ifindex� ifs_by_mac�line�curif�dev�toksr �capsr �nd6_opts�ip�ir! r! r" �parse^ s� � � � � zIfconfig.parsec C � | j S r> )r? r' r! r! r" � ifs_by_name� � zIfconfig.ifs_by_namec C rm r> )r@ r' r! r! r" rc � ro zIfconfig.ifs_by_macrg c C s� d }d|d v r!t |d �}t|j�}d|v r ||�d�d }n"ttt|d d���}d|v r9||�d�d }t d|d |f �}|j�d�d }t|j�|||d�fS )N�/rD � broadcast� r �%s/%s)�netmaskrq � prefixlen) r �strrt r r r] �with_prefixlenrS rj )r rg rq rj rt ru r! r! r" r^ � s$ ���zIfconfig._parse_inetc C s4 t dt|��D ]}|| dkr||d S qd S )NrH ru rD )r` rR )r rg rk r! r! r" �_get_prefixlen� s ��zIfconfig._get_prefixlenc C s� d }d|d v r-d}|d � d�\}}d|v r |� d�d }n| �|�}td||f �}n%d|d v rCt|d �}|d � d�d }n| �|�}td|d |f �}|sZ|jrZd}n|sa|jrad}t|j�||d�fS )N�%rD z link-localrp rs z site-local)ru �scope)rS rx r � is_link_local� is_site_localrv rj )r rg rz �ip6�restru rj r! r! r" r_ � s$ zIfconfig._parse_inet6c C s� t �d|d �}i }t|�dkrS|d �d�|d< d|d v r$d|d< nd|d< tdt|��D ]#}|| d krBt||d �|d < q/|| d krRt||d �|d < q/|S ) NrG rD rK r r TFrH r r )r[ rS rR r` r] )r rg r �ret�tr! r! r" rX s �zIfconfig._parse_flagsN)r7 r8 r9 r: r# r rv r r r r rl rn rc rP r ra r^ rx r_ rX r! r! r! r" r= O s (mr= )rY r[ � collectionsr � functoolsr � ipaddressr r r �typingr r r r r � cloudinitr �logging� getLoggerr7 �LOG�MAC_REr r= r! r! r! r" �<module> s :
