The keywords to `del_ip()` are the same object field names that may be used in the selectors or report filters: .. testcode:: with ndb.interfaces['eth0'] as eth0: eth0.del_ip(prefixlen=24) # remove all addresses with mask /24 A match function that may be passed to the `del_ip()` is the same as for `addresses.dump().select_records()`, and it gets a named tuple as the argument. The fields are named in the same way as address objects fields. So if you want to filter addresses by a pattern or the `prefixlen` field with a match function, you may use: .. testcode:: x1 with ndb.interfaces['eth0'] as eth0: eth0.add_ip('10.0.0.1/25') with ndb.interfaces['eth0'] as eth0: eth0.del_ip(lambda x: x.address.startswith('192.168')) eth0.del_ip(lambda x: x.prefixlen == 25) An empty `del_ip()` removes all the IP addresses on the interface: .. testcode:: x2 with ndb.interfaces['eth0'] as eth0: eth0.del_ip() # flush all the IP:s Accessing one address details ============================= Access an address as a separate RTNL object: .. testcode:: x3 print(ndb.addresses['192.168.122.28/24']) .. testoutput:: x3 :hide: {'target': 'localhost', 'address': '192.168.122.28', 'prefixlen': 24, 'tflags': 0, 'family': 2, 'index': 2, 'local': '192.168.122.28', 'flags': 512, 'scope': 0, 'label': 'eth0', 'broadcast': '192.168.122.255', 'anycast': None, 'multicast': None} Please notice that address objects are read-only, you may not change them, only remove old ones, and create new. � )� ifaddrmsg)�AddressFieldFilter� )� RTNL_Objectc C s� | � d||� |d d d r~|�d�r~| �d| j| jf ||d f��� }t|�s~| �d| j| j| jf ||d |d f� d S )N� addresses�header�typer �indexz� SELECT * FROM addresses WHERE f_target = %s AND f_index = %s AND f_family = 2 z� DELETE FROM routes WHERE f_target = %s AND f_RTA_OIF = %s OR f_RTA_IIF = %s )Z load_netlink�get�execute�plchZ fetchmany�len)�schema�target�eventr � r ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/pyroute2/ndb/objects/address.py�load_ifaddrmsg� s � � ��r �family� prefixlenr Z IFA_ADDRESSZ IFA_LOCALZ interfaces)Zf_targetZf_tflagsZf_indexr )�specs�classes� event_mapc sx e Zd ZdZeZeZdZe dd� �Z e dd� �Z e dd� �Z d d � Z � fd d �Zed d� �Ze dd� �Zdd� Z� ZS )�Addressr �addrc C sF |j r.|jj�d|j|jjjf |j d g�S |jj�d|j �S d S )Nz*SELECT count(*) FROM %s WHERE f_index = %sr zSELECT count(*) FROM %s)�chain�ndb� task_managerZ db_fetchone�tabler r )�cls�viewr r r �_count� s � ��zAddress._countc C sB |j r2|jjj}d||f }|j d |j d g}nd}g }||fS )Nz� WHERE main.f_target = %s AND main.f_index = %s r r � )r r r r )r r r �where�valuesr r r � _dump_where� s ��zAddress._dump_wherec c s< d}dV | � |�\}}|jj�|| |�D ] }|V q,d S )Na� SELECT main.f_target, main.f_tflags, intf.f_IFLA_IFNAME, main.f_IFA_ADDRESS, main.f_prefixlen FROM addresses AS main INNER JOIN interfaces AS intf ON main.f_index = intf.f_index AND main.f_target = intf.f_target )r ZtflagsZifname�addressr )r% r r Zdb_fetch)r r �reqr# r$ �recordr r r �summary� s zAddress.summaryc C s2 | j jfd }| j �d| || d | d f� d S )N� z� UPDATE interfaces SET f_tflags = %s WHERE f_index = %s AND f_target = %s r r )r r r )�self�markr r r r � mark_tflags s ��zAddress.mark_tflagsc s, t |d< t di| _tt| �j|i |�� d S )NZiclassZ load_rtnlmsg)r r �superr �__init__)r+ �argv�kwarg�� __class__r r r/ s zAddress.__init__c C s2 t |t�r.|| d kp,|d| d | d f kS d S )Nr& z%s/%ir �� isinstance�str)�left�rightr r r �compare_record# s �zAddress.compare_recordc C s t |t�r||d< |S )z� Address key normalization:: { ... } -> { ... } "10.0.0.1/24" -> {"address": "10.0.0.1", "prefixlen": 24} r& r4 )r � processed�specr r r �spec_normalize+ s zAddress.spec_normalizec C s@ d| � dd�| � d| � dd��| � d| � dd��| � dd�f S ) Nz %s/%s %s/%sr r" �labelr �localr& r )r )r+ r r r �key_repr8 s �zAddress.key_repr)�__name__� __module__� __qualname__r r Z msg_classr Z field_filter�api� classmethodr! r% r) r- r/ � staticmethodr9 r< r? � __classcell__r r r2 r r � s" r N)�__doc__Z pyroute2.netlink.rtnl.ifaddrmsgr Zpyroute2.requests.addressr �objectsr r Z sql_schemaZ unique_indexZ foreign_keyZ ifaddr_spec�initr r r r r �<module> s$ % ��� �
