okay bestie, so this is a page from the Kernel API Manual and it's literally about enum batadv_nl_attrs — the batman-adv netlink attributes. it's giving "the master list of every attribute name the batman-adv netlink interface fumbles around with" and you're gonna read all of it, no skipping ✨

✨ Constants ✨

like, the actual roster 💅 each one of these is a netlink attribute, and here's what each one is for:

• BATADV_ATTR_UNSPEC — the "unspecified" attribute, and its whole job is catching errors 🫶
• BATADV_ATTR_VERSION — the batman-adv version string
• BATADV_ATTR_ALGO_NAME — name of the routing algorithm
• BATADV_ATTR_MESH_IFINDEX — index of the batman-adv interface
• BATADV_ATTR_MESH_IFNAME — name of the batman-adv interface
• BATADV_ATTR_MESH_ADDRESS — mac address of the batman-adv interface
• BATADV_ATTR_HARD_IFINDEX — index of the non-batman-adv interface
• BATADV_ATTR_HARD_IFNAME — name of the non-batman-adv interface
• BATADV_ATTR_HARD_ADDRESS — mac address of the non-batman-adv interface
• BATADV_ATTR_ORIG_ADDRESS — originator mac address
• BATADV_ATTR_TPMETER_RESULT — result of the run (see batadv_tp_meter_status)
• BATADV_ATTR_TPMETER_TEST_TIME — time (msec) the run took
• BATADV_ATTR_TPMETER_BYTES — amount of acked bytes during the run
• BATADV_ATTR_TPMETER_COOKIE — session cookie to match the tp_meter session
• BATADV_ATTR_PAD — attribute used for padding for 64-bit alignment
• BATADV_ATTR_ACTIVE — flag indicating if the hard interface is active
• BATADV_ATTR_TT_ADDRESS — client MAC address
• BATADV_ATTR_TT_TTVN — translation table version
• BATADV_ATTR_TT_LAST_TTVN — previous translation table version
• BATADV_ATTR_TT_CRC32 — CRC32 over the translation table
• BATADV_ATTR_TT_VID — VLAN ID
• BATADV_ATTR_TT_FLAGS — translation table client flags
• BATADV_ATTR_FLAG_BEST — flags indicating the entry is the best
• BATADV_ATTR_LAST_SEEN_MSECS — time in milliseconds since last seen
• BATADV_ATTR_NEIGH_ADDRESS — neighbour MAC address
• BATADV_ATTR_TQ — TQ to the neighbour
• BATADV_ATTR_THROUGHPUT — estimated throughput to the neighbour
• BATADV_ATTR_BANDWIDTH_UP — reported uplink bandwidth
• BATADV_ATTR_BANDWIDTH_DOWN — reported downlink bandwidth
• BATADV_ATTR_ROUTER — gateway router MAC address
• BATADV_ATTR_BLA_OWN — flag indicating own originator
• BATADV_ATTR_BLA_ADDRESS — bridge loop avoidance claim MAC address
• BATADV_ATTR_BLA_VID — BLA VLAN ID
• BATADV_ATTR_BLA_BACKBONE — BLA gateway originator MAC address
• BATADV_ATTR_BLA_CRC — BLA CRC
• BATADV_ATTR_DAT_CACHE_IP4ADDRESS — client IPv4 address
• BATADV_ATTR_DAT_CACHE_HWADDRESS — client MAC address
• BATADV_ATTR_DAT_CACHE_VID — VLAN ID
• BATADV_ATTR_MCAST_FLAGS — per originator multicast flags
• BATADV_ATTR_MCAST_FLAGS_PRIV — private, own multicast flags
• BATADV_ATTR_VLANID — VLAN id on top of the mesh interface
• BATADV_ATTR_AGGREGATED_OGMS_ENABLED — whether the batman protocol messages of the mesh interface shall be aggregated or not.
• BATADV_ATTR_AP_ISOLATION_ENABLED — whether the data traffic going from a wireless client to another wireless client will be silently dropped.
• BATADV_ATTR_ISOLATION_MARK — the isolation mark which is used to classify clients as "isolated" by the Extended Isolation feature.
• BATADV_ATTR_ISOLATION_MASK — the isolation (bit)mask which is used to classify clients as "isolated" by the Extended Isolation feature.
• BATADV_ATTR_BONDING_ENABLED — whether the data traffic going through the mesh will be sent using multiple interfaces at the same time.
• BATADV_ATTR_BRIDGE_LOOP_AVOIDANCE_ENABLED — whether the bridge loop avoidance feature is enabled. This feature detects and avoids loops between the mesh and devices bridged with the mesh interface
• BATADV_ATTR_DISTRIBUTED_ARP_TABLE_ENABLED — whether the distributed arp table feature is enabled. This feature uses a distributed hash table to answer ARP requests without flooding the request through the whole mesh.
• BATADV_ATTR_FRAGMENTATION_ENABLED — whether the data traffic going through the mesh will be fragmented or silently discarded if the packet size exceeds the outgoing interface MTU.
• BATADV_ATTR_GW_BANDWIDTH_DOWN — defines the download bandwidth which is propagated by this node if BATADV_ATTR_GW_BANDWIDTH_MODE was set to 'server'.
• BATADV_ATTR_GW_BANDWIDTH_UP — defines the upload bandwidth which is propagated by this node if BATADV_ATTR_GW_BANDWIDTH_MODE was set to 'server'.
• BATADV_ATTR_GW_MODE — defines the state of the gateway features. Possible values are specified in enum batadv_gw_modes
• BATADV_ATTR_GW_SEL_CLASS — defines the selection criteria this node will use to choose a gateway if gw_mode was set to 'client'.
• BATADV_ATTR_HOP_PENALTY — defines the penalty which will be applied to an originator message's tq-field on every hop and/or per hard interface
• BATADV_ATTR_LOG_LEVEL — bitmask with to define which debug messages should be send to the debug log/trace ring buffer
• BATADV_ATTR_MULTICAST_FORCEFLOOD_ENABLED — whether multicast optimizations should be replaced by simple broadcast-like flooding of multicast packets. If set to non-zero then all nodes in the mesh are going to use classic flooding for any multicast packet with no optimizations.
• BATADV_ATTR_NETWORK_CODING_ENABLED — whether Network Coding (using some magic to send fewer wifi packets but still the same content) is enabled or not.
• BATADV_ATTR_ORIG_INTERVAL — defines the interval in milliseconds in which batman sends its protocol messages.
• BATADV_ATTR_ELP_INTERVAL — defines the interval in milliseconds in which batman emits probing packets for neighbor sensing (ELP).
• BATADV_ATTR_THROUGHPUT_OVERRIDE — defines the throughput value to be used by B.A.T.M.A.N. V when estimating the link throughput using this interface. If the value is set to 0 then batman-adv will try to estimate the throughput by itself.
• BATADV_ATTR_MULTICAST_FANOUT — defines the maximum number of packet copies that may be generated for a multicast-to-unicast conversion. Once this limit is exceeded distribution will fall back to broadcast.
• __BATADV_ATTR_AFTER_LAST — internal use 🙈
• NUM_BATADV_ATTR — total number of batadv_nl_attrs available
• BATADV_ATTR_MAX — highest attribute number currently defined 👑
