The existing code works mostly by luck. The PCI probe is done by the register and completes before the register returns thus allowing the other init code to run in time. Without a SEP or if unlucky this doesn't occur and you get an OOPS which for some reason causes grumpiness. As the season of good b^Hcheer is supposed to be approaching we should probably fix it.

linux/etherdevice.h already provides functions to classify different ethernet addresses. These inlineable functions should be used instead of custom functions. The check for multicast together with multicast can also be replaced with a single test for multicast because for every ethernet address x following is always true: is_broadcast_ether_addr(x) => is_multicast_ether_addr(x) or when looking more at the implementation: (FF:FF:FF:FF:FF:FF == x) => [(01:00:00:00:00:00 & x) != 00:00:00:00:00:00] Reported-by:

If the gateway client mode is active batman-adv will send the broadcasted DHCP requests via unicast to the currently selected best gateway. Therefore attached clients can profit from batman's knowledge about the network topology. Signed-off-by:

spin_lock_irqsave disables the IRQs and stores them inside the flags provided by the caller. This is needed to protect a bottom half handler or a user context critical section from being interrupted by an interrupt handler which also tries to acquire the spinlock and locks forever. The linux device drivers will receive the packets inside an interrupt handler and the network infrastructure will process them inside bottom half. Thus batman-adv will only run in user context and bottom half handlers. We can conclude that batman-adv doesn't share its own spinlocks with real interrupt handlers. This makes it possible to exchange the quite complex spin_lock_irqsave with spin_lock_bh which only stops bottom halves from running on the current cpu, but allows interrupt handlers to take over to keep the interrupt latency low.

The hash implementation is a complete implementation of a hash using buckets as hash entries and overflow buckets attached to them. The kernel already provides datastructures hlist_head and hlist_node which can be used to implement an hash using lists as hash buckets. So it is better to implement heavily used functionality on top of those instead of providing a full hash implementation. The rewrite changes the behavior of some functions slightly: * hash_add add elements to the front instead of the tail * hash_iterate doesn't provide pointer to access bucket->data directly, but it can be accessed using hlist_entry Reported-by:

hash_iterate is next to the function pointers the most called function related to hashes which benefits from inlining as it is uses in loops. Reported-by:

Sven Eckelmann authored
To enable inlining of the function pointers hashdata_choose_cb, hashdata_choose_cb and hashdata_free_cb, also the hash functions which uses them must be inlined by the called function. This should increase the performance, but also increases the size of the generated machine code slightly. Reported-by:
-
Sven Eckelmann authored
Function pointers cannot be inlined by a compiler and thus always has the overhead of an call. hashdata_choose_cb's are one of the most often called function pointers and its overhead must kept relative low. As first step, every function which uses this function pointer takes it as parameter instead of storing it inside the hash abstraction structure. This not generate any performance gain right now. The called functions must also be able to be inlined by the calling functions to enable inlining of the function pointer. Reported-by:

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:

Linus Lüssing authored
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). Signed-off-by: -

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:
