May, we managed to uncover and fix some important bugs in our new B.A.T.M.A.N. V algorithm. These are the fixes we came up with together with others that I collected in the past weeks: - avoid potential crash due to NULL pointer dereference in B.A.T.M.A.N. V routine when a neigh_ifinfo object is not found, by Sven Eckelmann - avoid use-after-free of skb when counting outgoing bytes, by Florian Westphal - fix neigh_ifinfo object reference counting imbalance when using B.A.T.M.A.N. V, by Sven Eckelmann. Such imbalance may lead to the impossibility of releasing the related netdev object on shutdown - avoid invalid memory access in case of error while allocating bcast_own_sum when a new hard-interface is added, by Sven Eckelmann - ensure originator address is updated in OMG/ELP packet content upon primary interface address change, by Antonio Quartulli - fix integer overflow when computing TQ metric (B.A.T.M.A.N. IV), by Sven Eckelmann - avoid race condition while adding new neigh_node which would result in having two objects mapping to the same physical neighbour, by Linus Lüssing - ensure originator address is initialized in ELP packet content on secondary interfaces, by Marek Lindner -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXO+ZsAAoJEJ4aZjxxc6bK7UEQALxcPqv2YtQhQCexHAPlmTxg 73uXuXpo0eWPxJh2FElcsHTHSt/l0/m/G8MEWCOfqI8MTeg+UTY5lXCY4iThtiY6 n08nl/CLkPNLuDGzAd7CpCM2jJ1iAzgJEVpUGQ6qoO5ekFvO09U/J/o6E8gDTX4I yc1kR3hcJeLbF6EUXEfTX/2THdFhkYSgHgZoGyM3eu43Zhv/6v454iEpqNxA/Ubr UngJTGSfqf20FidUt+xjbfptltTzj25Cp+VQ2DQ/LOuit0ChECjXwMfk0UkDHlKX bYPm1tcUJ0dzbR7cILMlzzzCSzH00leUk5GYYo59rAxBQiJ2j+92c2K0dcnv8cJJ q+GsZapyQFBIgPWS/TLtG1II3u8YWYvl+nEQXBDtPeRAjGoO4VwSbuatsf+enM8K i0c622iEc0b3cVe5H8reUh7SZMfMT/cQkEgpX5/psf8FWvEzeDv4HI3aUfVuSpck mEZAy59HeLWrF+KTScougv14vyoMmKfUcr5E1Oe4X1Ke9dpVvHGiI9wlqb/J0lfl rIc/5WI3ae/QAXkcPybanPEO8O0pBMP+Y4oCYpWmDu1qYfwZzDaSMqqEALQVVW2I 8Ta1gbzamgZDslf7YDSWOR0iyFAFcnMhT0qU6gv2+RGbcfwD+AGRLu5ufY/th0N3 L6AuFhvT/bxW6jN+iuAS =IACg -----END PGP SIGNATURE----- Merge tag 'batman-adv-fix-for-davem' of git://git.open-mesh.org/linux-merge Antonio Quartulli says: ==================== During the Wireless Battle Mesh v9 in Porto (PT) at the beginning of May, we managed to uncover and fix some important bugs in our new B.A.T.M.A.N.
