The following commit has been merged in the master branch: commit b278a6c18262a5cf3bc7adb7dd0d9b3730cd9113 Author: Sven Eckelmann <sven(a)narfation.org> Date: Tue May 3 13:10:06 2011 +0200 batman-adv: Avoid deadlock between rtnl_lock and s_active The hard_if_event is called by the notifier with rtnl_lock and tries to remove sysfs entries when a NETDEV_UNREGISTER event is received. This will automatically take the s_active lock. The s_active lock is also used when a new interface is added to a meshif through sysfs. In that situation we cannot wait for the rntl_lock before creating the actual batman-adv interface to prevent a deadlock. It is still possible to try to get the rtnl_lock and immediately abort the current operation when the trylock call failed.

The following commit has been merged in the master branch: commit 7e95055de79d92ebb1c5c9acde49fc6196ee8b54 Author: Sven Eckelmann <sven(a)narfation.org> Date: Tue May 3 11:51:38 2011 +0200 batman-adv: Remove unnecessary hardif_list_lock hardif_list_lock is unneccessary because we already ensure that no multiple admin operations can take place through rtnl_lock. hardif_list_lock only adds additional overhead and complexity. Critical functions now check whether they are called with rtnl_lock using ASSERT_RTNL. It indirectly fixes the problem that orig_hash_del_if() expects that only one interface is deleted from hardif_list at a time, but hardif_remove_interfaces() removes all at once and then calls orig_hash_del_if().

The following commit has been merged in the master branch: commit a2a260389ea0a902479430594361eaa23b584b26 Author: David Decotigny <decot(a)google.com> Date: Wed May 4 10:25:32 2011 +0200 batman-adv: cosmetic: Use ethtool ethtool_cmd_speed API This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.
