[batman-adv] master: batman-adv: prevent potential hlist double deletion (4729a33)

by postmaster＠open-mesh.org

Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 4729a33528e05ea858d8337769584cb49961fc0e Author: Marek Lindner <mareklindner(a)neomailbox.ch> Date: Mon Jun 22 00:30:23 2015 +0800 batman-adv: prevent potential hlist double deletion The hlist_del_rcu() call in batadv_tt_global_size_mod() does not check if the element still is part of the list prior to deletion. The atomic list counter should prevent the worst but converting to hlist_del_init_rcu() ensures the element can't be deleted more than once.

[batman-adv] maint: batman-adv: initialize up/down values when adding a gateway (3c92b63)

by postmaster＠open-mesh.org

Repository : ssh://git@open-mesh.org/batman-adv On branch : maint >--------------------------------------------------------------- commit 3c92b633715b7eca80dc7a2347e0e4dbcce1f018 Author: Simon Wunderlich <simon(a)open-mesh.com> Date: Wed Jun 24 14:50:19 2015 +0200 batman-adv: initialize up/down values when adding a gateway Without this initialization, gateways which actually announce up/down bandwidth of 0/0 could be added. If these nodes get purged via _batadv_purge_orig() later, the gw_node structure does not get removed since batadv_gw_node_delete() updates the gw_node with up/down bandwidth of 0/0, and the updating function then discards the change and does not free gw_node. This results in leaking the gw_node structures, which references other structures: gw_node -> orig_node -> orig_node_ifinfo -> hardif. When removing the interface later, the open reference on the hardif may cause hangs with the infamous "unregister_netdevice: waiting for mesh1 to become free. Usage count = 1" message.
