Antonio Quartulli says: ==================== this is another set of changes intended for net-next/linux-3.13. (probably our last pull request for this cycle) Patches 1 and 2 reshape two of our main data structures in a way that they can easily be extended in the future to accommodate new routing protocols. Patches from 3 to 9 improve our routing protocol API and its users so that all the protocol-related code is not mixed up with the other components anymore. Patch 10 limits the local Translation Table maximum size to a value such that it can be fully transfered over the air if needed. This value depends on fragmentation being enabled or not and on the mtu values. Patch 11 makes batman-adv send a uevent in case of soft-interface destruction while a "bat-Gateway" was configured (this informs userspace about the GW not being available anymore). Patches 13 and 14 enable the TT component to detect non-mesh client flag changes at runtime (till now those flags where set upon client detection and were not changed anymore). Patch 16 is a generalisation of our user-to-kernel space communication (and viceversa) used to exchange ICMP packets to send/received to/from the mesh network. Now it can easily accommodate new ICMP packet types without breaking the existing userspace API anymore. Remaining patches are minor changes and cleanups. ==================== Signed-off-by: David S.

Hannes Frederic Sowa says: ==================== initialize fragment hash secrets with net_get_random_once This series switches the inet_frag.rnd hash initialization to net_get_random_once. Included patches: ipv4: initialize ip4_frags hash secret as late ipv6: split inet6_hash_frag for netfilter and inet: remove old fragmentation hash initializing ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

All fragmentation hash secrets now get initialized by their corresponding hash function with net_get_random_once. Thus we can eliminate the initial seeding. Also provide a comment that hash secret seeding happens at the first call to the corresponding hashing function. Cc: David S.

Defer the fragmentation hash secret initialization for IPv6 like the previous patch did for IPv4. Because the netfilter logic reuses the hash secret we have to split it first. Thus introduce a new nf_hash_frag function which takes care to seed the hash secret. Cc: David S.

Defer the generation of the first hash secret for the ipv4 fragmentation cache as late as possible. ip4_frags.rnd gets initial seeded by inet_frags_init and regulary reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly from ip_fragment.c in which case we initialize the secret directly. If we first get called by inet_frag_secret_rebuild we install a new secret by a manual call to get_random_bytes. This secret will be overwritten as soon as the first call to ipqhashfn happens. This is safe because we won't race while publishing the new secrets with anyone else. Cc: Eric Dumazet <edumazet@google.com> Cc: "David S.

Jingoo Han syas: ==================== ethernet: remove unnecessary pci_set_drvdata() part 4 Since commit 0998d063 (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Currently net_secret_init does not get inlined, so we always have a call to net_secret_init even in the fast path. Let's specify net_secret_init as __always_inline so we have the nop in the fast-path without the call to net_secret_init and the unlikely path at the epilogue of the function. jump_labels handle the inlining correctly.

2e685cad (tcp_memcontrol: Kill struct tcp_memcontrol) falsly modified the access to memory_pressure of sk->sk_prot->memory_pressure. The patch did modify the memory_pressure-field of struct cg_proto, but not the one of struct proto. So, the access to sk_prot->memory_pressure should not be changed.

Instead of handling icmp packets only up to length of icmp_packet_rr, the code should handle any icmp length size. Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.

Flags covered by TT_SYNC_MASK are kept in sync among the nodes in the network and therefore they have to be considered while computing the global/local table CRC. In this way a generic originator is able to understand if its table contains the correct flags or not. Bits from 4 to 7 in the TT flags fields are now reserved for "synchronized" flags only. This allows future developers to add more flags of this type without breaking compatibility. It's important to note that not all the remote TT flags are synchronised. This comes from the fact that some flags are used to inject an information once only.

Some flags (i.e. the WIFI flag) may change after that the related client has already been announced. However it is useful to informa the rest of the network about this change. Add a runtime-flag-switch detection mechanism and re-announce the related TT entry to advertise the new flag value. This mechanism can be easily exploited by future flags that may need the same treatment.

Upcoming changes need to perform other checks on the incoming net_device struct. To avoid performing dev_get_by_index() for each and every check, it is better to move it outside of is_wifi_iface() and search the netdev object once only.

The local translation table size is limited by what can be transferred from one node to another via a full table request. The number of entries fitting into a full table request depend on whether the fragmentation is enabled or not. Therefore this patch introduces a max table size check and refuses to add more local clients when that size is reached. Moreover, if the max full table packet size changes (MTU change or fragmentation is disabled) the local table is downsized instantaneously.

Some operations executed on an orig_node depends on the current routing algorithm being used. To easily make this mechanism routing algorithm agnostic add a orig_node specific API that each algorithm can populate with its own routines. Such routines are then invoked by the code when needed, without knowing which routing algorithm is currently in use With this patch 3 API functions are added: - orig_free (to free routing depending internal structs) - orig_add_if (to change the inner state of an orig_node when a new hard interface is added) - orig_del_if (to change the inner state of an orig_node when an hard interface is removed) Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
