This change allows nodes to handle the TT table on a per-VLAN basis. This is needed because nodes may have to store only some of the global entries advertised by another node. In this scenario such nodes would re-create only a partial global table and would not be able to compute a correct CRC anymore. This patch splits the logic and introduces one CRC per VLAN. In this way a node fetching only some entries belonging to some VLANs is still able to compute the needed CRCs and still check the table correctness. With this patch the shape of the TVLV-TT is changed too because now a node needs to advertise all the CRCs of all the VLANs that it is wired to. The debug output of the local Translation Table now shows the CRC along with each entry since there is not a common value for the entire table anymore. Signed-off-by:

A TT response may be prepared and sent while the local or global translation table is getting updated. The worst case is when one of the tables is accessed after its content has been recently updated but the metadata (TTVN/CRC) has not yet. In this case the reader will get a table content which does not match the TTVN/CRC. This will lead to an inconsistent state and so to a TT recovery. To avoid entering this situation, put a lock around those TT operations recomputing the metadata and around the TT Response creation (the latter is the only reader that accesses the metadata together with the table).

With this patch the functions batadv_send_skb_unicast() and batadv_send_skb_unicast_4addr() are further refined into batadv_send_skb_via_tt(), batadv_send_skb_via_tt_4addr() and batadv_send_skb_via_gw(). This way we avoid any "guessing" about where to send a packet in the unicast forwarding methods and let the callers decide. This is going to be useful for the upcoming multicast related patches in particular. Further, the return values were polished a little to use the more appropriate NET_XMIT_* defines. Signed-off-by:

AP isolation has to be enabled on one VLAN interface only. This patch moves the AP isolation attribute to the per-vlan interface attribute set, enabling it to have a different value depending on the selected vlan. Signed-off-by:

Each VLAN can now have its own set of attributes which are exported through a new subfolder in the sysfs tree. Each VLAN created on top of a soft_iface will have its own subfolder. The subfolder is named "vlan%VID" and it is created inside the "mesh" sysfs folder belonging to batman-adv. Attributes corresponding to the untagged LAN are stored in the root sysfs folder as before. This patch also creates all the needed macros and data structures to easily handle new VLAN spacific attributes. Signed-off-by:

Since batman-adv is now fully VLAN-aware, a proper framework able to handle per-vlan-interface attributes is needed. Those attributes will affect the associated VLAN interface only, rather than the real soft_iface (which would result in every vlan interface having the same attribute configuration). To make the code simpler and easier to extend, attributes associated to the standalone soft_iface are now treated like belonging to yet another vlan having a special vid. This vid is different from the others because it is made up by all zeros and the VLAN_HAS_TAG bit is not set. Signed-off-by:

The same IP subnet can be used on different VLANs, therefore DAT has to differentiate whether the IP to resolve belongs to one or the other virtual LAN. To accomplish this task DAT has to deal with the VLAN tag and store it together with each ARP entry. Signed-off-by:

now that each TT entry is characterised by a VLAN ID, the latter has to be taken into consideration when computing the local/global table CRC as it would be theoretically possible to have the same client in two different VLANs Signed-off-by:

To make the translation table code VLAN-aware, each entry must carry the VLAN ID which it belongs to. This patch adds such attribute to the related TT structures. Signed-off-by:

Remove the specialized code in __tcp_retransmit_skb() that tries to trim any ACKed payload preceding a FIN before we retransmit (this was added in 1999 in v2.2.3pre3). This trimming code was made unreachable by the more general code added above it that uses tcp_trim_head() to trim any ACKed payload, with or without a FIN (this was added in "[NET]: Add segmentation offload support to TCP." in 2002 circa v2.5.33).

When checking statistics or changing parameters on a link, the link_find_link function is used to locate the link with a given name. The complex method of deconstructing the name into local and remote address/interface is error prone and may fail if the interface names contains special characters. We change the lookup method to iterate over the list of nodes and compare the link names. Signed-off-by:

link_cmd_set_value() takes commands for link, bearer and media related configuration. Genereally the function returns 0 when a command is recognized, and -EINVAL when it is not. However, in the switch for link related commands it returns 0 even when the command is unrecognized. This will sometimes make it look as if a failed configuration command has been successful, but has otherwise no negative effects. We remove this anomaly by returning -EINVAL even for link commands. We also rework all three switches to make them conforming to common kernel coding style. Signed-off-by:

Currently, rcv_msg() always returns zero on a packet delivery upcall from net_device. To make its behavior more compliant with the way this API should be used, we change this to let it return NET_RX_SUCCESS (which is zero anyway) when it is able to handle the packet, and NET_RX_DROP otherwise. The latter does not imply any functional change, it only enables the driver to keep more accurate statistics about the fate of delivered packets. Signed-off-by:

tipc_block_bearer() currently takes a bearer name (const char*) as argument. This requires the function to make a lookup to find the pointer to the corresponding bearer struct. In the current code base this is not necessary, since the only two callers (tipc_continue(),recv_notification()) already have validated copies of this pointer, and hence can pass it directly in the function call. We change tipc_block_bearer() to directly take struct tipc_bearer* as argument instead. Signed-off-by:

TIPC 'bearer' exists as an abstract concept, while 'media' is deemed a specific implementation of a bearer, such as Ethernet or Infiniband media. When a component inside TIPC wants to control a specific media, it only needs to access the generic bearer API to achieve this. However, in the current media implementations, the 'bearer' name is also extensively used in media specific function and variable names. This may create confusion, so we choose to replace the term 'bearer' with 'media' in all function names, variable names, and prefixes where this is what really is meant. Note that this change is cosmetic only, and no runtime behaviour changes are made here. Signed-off-by:
