vis; branch, pu/makefile_cleanup, updated. v0.3.2-25-gbe46dab

by postmaster＠open-mesh.org

The following commit has been merged in the pu/makefile_cleanup branch: commit be46dabff125d4486439268313fccc3d22ce88f7 Author: Sven Eckelmann <sven(a)narfation.org> Date: Tue Jul 5 10:54:59 2011 +0200 vis: Replace version info instead of appending them The version number of vis can get revision numbers added. This is useful to give hints about the revision of a distribution package and the used patchset or the commit which was used to build it. The prepended source number or branch name doesn't add any additional information which would help to identify problems and can therefore be omitted.

The following commit has been merged in the maint branch: commit 913c412bd4320bfe3b1acfaa467e07e87bb41789 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.
