      batman-adv: keep track of when unicast packets are sent · 95d39278
      由 Antonio Quartulli 提交于 
      To enable ELP to send probing packets over wireless links
only if needed, batman-adv must keep track of the last time
it sent a unicast packet towards every neighbour.

For this purpose a 2 main changes are introduced:
1) a new member of the elp_neigh_node structure stores the
   last time a unicast packet was sent towards this neighbour;
2) a wrapper function for sending unicast packets is
   implemented. This function will simply update the member
   describe din point 1) and then forward the packet to the
   real sending routine.

Point 2) implies that any code-path leading to a unicast
sending now has to use the new wrapper.

      batman-adv: avoid DAT to mess up LAN state · f202a666
      由 Antonio Quartulli 提交于 
      When a node running DAT receives an ARP request from the LAN for the
first time, it is likely that this node will request the ARP entry
through the distributed ARP table (DAT) in the mesh.

Once a DAT reply is received the asking node must check if the MAC
address for which the IP address has been asked is local. If it is, the
node must drop the ARP reply bceause the client should have replied on
its own locally.

Forwarding this reply means fooling any L2 bridge (e.g. Ethernet
switches) lying between the batman-adv node and the LAN. This happens
because the L2 bridge will think that the client sending the ARP reply
lies somewhere in the mesh, while this node is sitting in the same LAN.

      batman-adv: Add required includes to all files · 1e2c2a4f
      由 Sven Eckelmann 提交于 
      The header files could not be build indepdent from each other. This is
happened because headers didn't include the files for things they've used.
This was problematic because the success of a build depended on the
knowledge about the right order of local includes.

Also source files were not including everything they've used explicitly.
Instead they required that transitive includes are always stable. This is
problematic because some transitive includes are not obvious, depend on
config settings and may not be stable in the future.

The order for include blocks are:

 * primary headers (main.h and the *.h file of a *.c file)
 * global linux headers
 * required local headers
 * extra forward declarations for pointers in function/struct declarations

The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h.
This header file is shared with userspace applications like batctl and must
therefore build together with userspace applications. The header
linux/bitops.h is not part of the uapi headers and linux/if_ether.h
conflicts with the musl implementation of netinet/if_ether.h. The
maintainers rejected the use of __KERNEL__ preprocessor checks and thus
these two headers are only in main.h. All files using packet.h first have
to include main.h to work correctly.

      batman-adv: Use common Jenkins Hash implementation · 36fd61cb
      由 Sven Eckelmann 提交于 
      An unoptimized version of the Jenkins one-at-a-time hash function is used
and partially copied all over the code wherever an hashtable is used.
Instead the optimized version shared between the whole kernel should be
used to reduce code duplication and use better optimized code.

Only the DAT code must use the old implementation because it is used as
distributed hash function which has to be common for all nodes.

      net: add __pskb_copy_fclone and pskb_copy_for_clone · bad93e9d
      由 Octavian Purdila 提交于 
      There are several instances where a pskb_copy or __pskb_copy is
immediately followed by an skb_clone.

Add a couple of new functions to allow the copy skb to be allocated
from the fclone cache and thus speed up subsequent skb_clone calls.
