The following commit has been merged in the master branch: commit 48100bac89a6161ca53dd65697fe635f77986686 Author: Antonio Quartulli <ordex(a)autistici.org> Date: Sun Oct 30 12:17:33 2011 +0100 batman-adv: create a common substructure for tt_global/local_entry Several functions in the translation table management code assume that the tt_global_entry and tt_local_entry structures have the same initial fields such as 'addr' and 'hash_entry'. To improve the code readability and to avoid mistakes in later changes, a common substructure that substitute the shared fields has been introduced (struct tt_common_entry). Thanks to this modification, it has also been possible to slightly reduce the code length by merging some functions like compare_ltt/gtt() and tt_local/global_hash_find() Signed-off-by: Antonio Quartulli <ordex(a)autistici.org> Signed-off-by: Sven Eckelmann <sven(a)narfation.org> diff --git a/net/batman-adv/translation-table.c b/net/batman-adv/translation-table.c index 78b9528..76134bc 100644 --- a/net/batman-adv/translation-table.c +++ b/net/batman-adv/translation-table.c @@ -36,18 +36,9 @@ static void _tt_global_del(struct bat_priv *bat_priv, static void tt_purge(struct work_struct *work);

The following commit has been merged in the master branch: commit 03fc3070457dc0e6a717a2e732af93ef1cb2ae51 Author: Antonio Quartulli <ordex(a)autistici.org> Date: Sun Dec 4 12:26:50 2011 +0100 batman-adv: in case of roaming mark the client with TT_CLIENT_ROAM In case of a client roaming from node A to node B, the latter have to mark the corresponding global entry with TT_CLIENT_ROAM (instead of TT_CLIENT_PENDING). Marking a global entry with TT_CLIENT_PENDING will end up in keeping such entry forever (because this flag is only meant to be used with local entries and it is never checked on global ones). In the worst case (all the clients roaming to the same node A) the local and the global table will contain exactly the same clients. Batman-adv will continue to work, but the memory usage is duplicated.
