Trailing spaces at the end of a line or before a tab are against Documentation/CodingStyle "3.1: Spaces" and should be avoided. It is also common style to add a single space after commas unless it is followed either by a newline or a tab. Reported-by:

We must ensure that all pointer to a socket buffer are updated when we copy a socket buffer and free our reference to the old one. Another part of the kernel could also free its reference which maybe removes the buffer completely. In that situation we would would feed wrong information to the routing algorithm after the memory area is written again by someone else. Signed-off-by:

This patch limits the queue lengths of batman and broadcast packets. BATMAN packets are held back for aggregation and jittered to avoid interferences. Broadcast packets are stored to be sent out multiple times to increase the probability to be received by other nodes in lossy environments. Especially in extreme cases like broadcast storms, the queues have been seen to run full, eating up all the memory and triggering the infamous OOM killer. With the queue length limits introduced in this patch, this problem is avoided. Each queue is limited to 256 entries for now, resulting in 1 MB of maximum space available in total for typical setups (assuming one packet including overhead does not require more than 2000 byte). This should also be reasonable for smaller routers, otherwise the defines can be tweaked later. This third version of the patch does not increase the local broadcast sequence number when the queue is already full. Signed-off-by:

BATMAN and broadcast packets are tracked with a sequence number window of currently 64 entries to measure and avoid duplicates. Packets which have a sequence number smaller than the newest received packet minus 64 are not within this sequence number window anymore and are called "old packets" from now on. When old packets are received, the routing code assumes that the host of the originator has been restarted. This assumption however might be wrong as packets can also be delayed by NIC drivers, e.g. because of long queues or collision detection in dense WiFi? environments. This behaviour can be reproduced by doing a broadcast ping flood in a dense node environment. The effect is that the sequence number window is jumping forth and back, accepting and forwarding any packet (because packets are assumed to be "new") and causing loops. To overcome this problem, the sequence number handling has been reorganized. When an old packet is received, the window is reset back only once. Other old packets are dropped for (currently) 30 seconds to "protect" the new sequence number and avoid the hopping as described above. The reorganization brings some code cleanups (at least i hope you feel the same) and also fixes a bug in count_real_packets() which falsely updated the last_real_seqno for slightly older packets within the seqno window if they are no duplicates. This second version of the patch also fixes a problem where for seq_diff==64 bit_shift() reads from outside of the seqno window, and removes the loop for seq_diff == -64 which was present in the first patch. The third iteration also adds a window for the next expected sequence numbers. This minimizes sequence number flapping for packets with very big differences (e.g. 3 packets with seqno 0, 25000 and 50000 might still cause problems without this window). Signed-off-by:

Instead of having a single /proc file "interfaces" in which you have to echo the wanted interface batman-adv will create a subfolder in each suitable /sys/class/net folder. This subfolder contains files for the interface specific settings. For example, mesh_iface to add/remove an interface from a virtual mesh network (at the moment only bat0 is supported). Example: echo bat0 > /sys/class/net/eth0/batman-adv/mesh_iface to deactivate: echo none > /sys/class/net/eth0/batman-adv/mesh_iface Interfaces which are not compatible with batman-adv won't contain the batman-adv folder, therefore can't be activated. Not supported are: loopback, non-ethernet, non-ARP and virtual mesh network interfaces Signed-off-by:

This is the first patch in a series of patches which aim to convert all batman-adv /proc files to sysfs. To keep the changes in a digestable size it has been split up into smaller chunks. During the transition period batman-adv will use /proc as well as sysfs. As a first step the following files have been converted: aggregate_ogm, originators, transtable_global, transtable_local Signed-off-by:

The code here is testing to see if "i" is passed the end of the array. The original code works probably, but it's not the cleanest way. Andrew Lunn suggested that I also remove all the hard coded references to 256 so I have done that as well. Signed-off-by:

We are now having a newer, more neutral vis output so that we won't have to change the kernelmodule for adding support of new vis output formats. This patch adds an explanation about this in the README file of batman-adv and removes the description about the dot/json format (they will be added to the README of batctl). Signed-off-by:

So far, neighbour's secondary interface OGMs can involuntarily piggyback on primary interface OGMs that arrived on the same secondary interface before. Secondary interface OGMs should NEVER leave their direct neighbour broadcast domain! This patch ensures that secondary interface OGMs can only be aggregated to other secondary interface OGMs. Signed-off-by:

batman-adv aggregates routing packets to reduce the number of packets in the air. Every outgoing packet is compared with other packets in the buffer to determine whether it can be aggregated or not. Packets sent at a lower interval can be held back longer to maximize the aggregation. Due to insufficient checking batman-adv held back all packets for a certain time depending on its own lowest interval rate which slowed down all other nodes. Reported-by:

"tcpdump" and "batctl td" will receive packets with a wrong sequence number on systems with a different endianess than network byte order. This happens due to the reordering of bytes in the function which handles aggregated bat packets. The function which receives the bat packets must ensure that these buffers aren't shared with anything else before that function tries to write into it. Otherwise it has to copy the buffers so it is save again to change them. Reported-by:

If we haven't set the module to MODULE_ACTIVE state before (in general, no interface has yet been added to batman-adv) then the hna table is not initialised yet. If the kernel changes the mac address of the bat0 interface at this moment then an hna_local_add() called by interface_set_mac_addr() then resulted in a null pointer derefernce. With this patch we are now explicitly checking before if the state is MODULE_ACTIVE right now so that we can assume having an initialised hna table. Signed-off-by:
