When having a mixed topology of both very mobile and rather static nodes, you are usually best advised to set the originator interval on all nodes to a level best suited for the most mobile node. However, if most of the nodes are rather static, this can create a lot of undesired overhead as a trade-off then. If setting the interval too low on the static nodes, a mobile node might be chosen as a router for too long, not switching away from it fast enough because of its mobility and the low frequency of ogms of static nodes. Exposing the hop_penalty is especially useful for the stated scenario: A static node can keep the default originator interval, a mobile node can select a quicker one resulting in faster route updates towards this mobile node. Additionally, such a mobile node could select a higher hop penalty (or even set it to 255 to disable acting as a router for other nodes) to make it less desirable, letting other nodes avoid selecting this mobile node as a router.

We actually do not need an extra struct device variable, therefore replacing them with defines that directly get the bat_priv or net_device. This further reduces the code size in bat_sysfs.c and especially shortens some macros. Signed-off-by:

Sysfs configuration options that just took a boolean value (enable(d)/disable(d)/0/1) and integer setting basically all had the same structure. To avoid even more copy and pasting in the future and to make introducing new configuration parameters for batman-adv simpler, more generic wrapper functions are being introduced with this commit. They can deal with boolean and unsigned integer parameters, storing them in the specified atomic_t variables. Signed-off-by:

Both sysfs entries and variable names shall be as descriptive as possible while not exceeding a certain length. This patch renames bat_priv atomics to be equally descriptive with their according sysfs entries. Unifying sysfs and bat_priv atomic names also makes it easier to find each others pendant. The reduced ("type"-)information which was previously indicated with a _enabled for booleans got substituted by a comment in bat_priv. This patch has also been done in regards for the future BAT_ATTR_* macros (they only need one name argument instead of a file and variable name).

By connecting multiple batman-adv mesh nodes to the same ethernet segment a loop can be created when the soft-interface is bridged into that ethernet segment. A simple visualization of the loop involving the most common case - a LAN as ethernet segment: node1 <-- LAN --> node2 | | wifi <-- mesh --> wifi Packets from the LAN (e.g. ARP broadcasts) will circle forever from node1 or node2 over the mesh back into the LAN. This patch adds the functionality to detect other batman-adv nodes connected to the LAN and select a 'gateway' to talk to the non-batman-adv devices on this LAN. All traffic from and to the mesh will be handled by this gateway to avoid the loop. OGMs received via the soft-interface are interpreted as 'port announcements' to locate potential batman-adv nodes. The patch can also deal with vlans on top of batX and offers a list of LAN neighbors via debugfs. Signed-off-by:

The unicast_frag_send_skb() function expected 'raw' packets (without any batman-adv header) to fragment them. This needs to be changed, so that this function is able to fragment packets that already traveled inside the mesh but need to be fragmented now. Signed-off-by:

We call a lot of the netdevice code when holding if_list_lock which will spin the whole time. This is not necessary because we only want to protect the access to the list to be serialized. An extra queue can be used which hold all interfaces which should be removed and then use that queue without any locks for netdevice cleanup. Reported-by:

eth_type_trans tries to pull data with the length of the ethernet header from the skb. We only ensured that enough data for the first ethernet header and the batman header is available in non-paged memory of the skb and not for the ethernet after the batman header. eth_type_trans would fail sometimes with drivers which don't ensure that all there data is perfectly linearised.

This driver is for the Security Processor, a dedicated encryption and decryption driver that is used on the Intel mobile platform. This has been checked with checkpatch and there are four warnings for lines over 80 charactors. There is one compile warning. This is for a function that is only used if the rar register driver is needed. There is an ifdef in a header file that stubs out the rar register driver if the rar register is not configured. This driver does add a configuration, which is CONFIG_DX_SEP. Signed-off-by:
