2016-01-16batman-adv: Avoid recursive call_rcu for batadv_bla_claimSven Eckelmann1-7/+3
The batadv_claim_free_ref function uses call_rcu to delay the free of the batadv_bla_claim object until no (already started) rcu_read_lock is enabled anymore. This makes sure that no context is still trying to access the object which should be removed. But batadv_bla_claim also contains a reference to backbone_gw which must be removed. The reference drop of backbone_gw was done in the call_rcu function batadv_claim_free_rcu but should actually be done in the batadv_claim_release function to avoid nested call_rcus. This is important because rcu_barrier (e.g. batadv_softif_free or batadv_exit) will not detect the inner call_rcu as relevant for its execution. Otherwise this barrier will most likely be inserted in the queue before the callback of the first call_rcu was executed. The caller of rcu_barrier will therefore continue to run before the inner call_rcu callback finished.

2015-12-16batman-adv: lock crc access in bridge loop avoidanceSimon Wunderlich1-5/+30
We have found some networks in which nodes were constantly requesting other nodes BLA claim tables to synchronize, just to ask for that again once completed. The reason was that the crc checksum of the asked nodes were out of sync due to missing locking and multiple writes to the same crc checksum when adding/removing entries. Therefore the asked nodes constantly reported the wrong crc, which caused repeating requests. To avoid multiple functions changing a backbone gateways crc entry at the same time, lock it using a spinlock.

2015-06-07batman-adv: Add required includes to all filesSven Eckelmann1-8/+30
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.

2015-06-07batman-adv: Use common Jenkins Hash implementationSven Eckelmann1-12/+4

Instead the optimized version shared between the whole kernel should be used to reduce code duplication and use better optimized code.

2013-10-20batman-adv: make the backbone gw check VLAN specificAntonio Quartulli1-8/+11
The backbone gw check has to be VLAN specific so that code using it can specify VID where the check has to be done. In the TT code, the check has been moved into the tt_global_add() function so that it can be performed on a per-entry basis instead of ignoring all the TT data received from another backbone node. Only TT global entries belonging to the VLAN where the backbone node is connected to are skipped. All the other spots where the TT code was checking whether a node is a backbone have been removed. Moreover, batadv_bla_is_backbone_gw_orig() now returns bool since it used to return only 1 or 0.

There are several functions which might reallocate skb data. Currently some places keep reusing their old ethhdr pointer regardless of whether they became invalid after such a reallocation or not.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-02-28hlist: drop the node parameter from iteratorsSasha Levin1-24/+15
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

2013-01-12batman-adv: unify and properly print hex valuesAntonio Quartulli1-9/+9
Values are printed in hexadecimal format in several points in the code, but they are not printed using the same format string. This patches unifies the format used for such numbers so that they look the same everywhere. Given the fact that all the variables printed as hexadecimal are 16 bit long, this is the chosen printing format: %#.4x Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
2012-11-21batman-adv: Fix broadcast duplist for fragmentationSimon Wunderlich1-11/+7
If the skb is fragmented, the checksum must be computed on the individual fragments, just using skb->data may fail on fragmented data. Instead of doing linearizing the packet, use the new batadv_crc32 to do that more efficiently- it should not hurt replacing the old crc16 by the new crc32.
