The bat_algo.h had some functions declared which were not part of the bat_algo.c file. These are instead stored in bat_v.c and bat_iv_ogm.c. The declaration should therefore be also in bat_v.h and bat_iv_ogm,h to make them easier to find.

The bat_algo functionality in main.c is mostly unrelated to the rest of the content. It still takes up a large portion of this source file (~15%, 103 lines). Moving it to a separate file makes it better visible as a main component of the batman-adv implementation and hides it less in the other helper functions in main.c.

Unfragmented frames which traverse a node have their skb->priority set by looking at the IP ToS byte, or the 802.1p header. However for fragments this is not possible, only one of the fragments will contain the headers. Instead, place the priority into the fragment header and on receiving a fragment, use this information to set the skb->priority for when the fragment is forwarded.

sch_atm returns this when TC_ACT_SHOT classification occurs. But all other schedulers that use tc_classify (htb, hfsc, drr, fq_codel ...) return NET_XMIT_SUCCESS | __BYPASS in this case so just do that in atm. BATMAN uses it as an intermediate return value to signal forwarding vs. buffering, but it did not return POLICED to callers outside of BATMAN.

It is easier to understand that the returned value of a specific function doesn't have to be 0 when the functions was successful when the actual return type is bool.

_batadv_update_route requires that the caller already has a valid reference for neigh_node. It is therefore not possible that it has an reference counter of 0 and was still given to this function The kref_get function instead WARNs (with debug information) when the reference counter would still be 0. This makes a bug in batman-adv better visible because kref_get_unless_zero would have ignored this problem.

_batadv_update_route rcu_derefences orig_ifinfo->router outside of a spinlock protected region to print some information messages to the debug log. But this pointer is not checked again when the new pointer is assigned in the spinlock protected region. Thus is can happen that the value of orig_ifinfo->router changed in the meantime and thus the reference counter of the wrong router gets reduced after the spinlock protected region. Just rcu_dereferencing the value of orig_ifinfo->router inside the spinlock protected region (which also set the new pointer) is enough to get the correct old router object.

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.

With the new interface alternating, the first hop may send packets in a round robin fashion to it's neighbors because it has multiple valid routes built by the multi interface optimization.
