Fanouts allow packet capturing to be demuxed to a set of AF_PACKET sockets. Two fanout policies are implemented: 1) Hashing based upon skb->rxhash 2) Pure round-robin An AF_PACKET socket must be fully bound before it tries to add itself to a fanout. All AF_PACKET sockets trying to join the same fanout must all have the same bind settings. Fanouts are identified (within a network namespace) by a 16-bit ID. The first socket to try to add itself to a fanout with a particular ID, creates that fanout. When the last socket leaves the fanout (which happens only when the socket is closed), that fanout is destroyed. Signed-off-by:David S. Miller <davem@davemloft.net>

The version number of modules build outside of the tree can get revision numbers added. This is useful to give hints about the revision of a distribution package and the used patchset. The prepended source number or branch name doesn't add any additional information which would help to identify problems and can therefore be omitted. Signed-off-by:

The packet aggregation needs to ensure that only compatible packets are aggregated. Some of the checks are based on the interface number while assuming that the first interface also is the primary interface which is not always the case. This patch addresses the issue by using the primary_if pointer. Reported-by:

The primary interface OGM has to be broadcasted on all hard-interfaces even if the primary interface is not the first interface (if_num = 0). Therefore the code has to compare the originating interface with the primary interface instead of checking the if_num. Reported-by:

The tt_local_entry structure now has a 'flags' field. This helps to unify the flags format to all the client related structures (tt_global_entry and tt_change). The 'never_purge' field is now encoded in the 'flags' one. To optimise the usage of this field, its length has been increased to 16bit in order to use the eight leading bits (from 0 to 7) to store flags that have to be sent on the wire, while the eight ending ones are used for local computation only. Moreover 'enum tt_change_flags' is now called 'enum tt_client_flags' and the defined values apply to the tt_local_entry, tt_global_entry and the tt_change 'flags' field. Signed-off-by:

CCID-2's cwnd increases like TCP during slow-start, which has implications for * the local Sequence Window value (should be > cwnd), * the Ack Ratio value. Hence an exponential growth, if it does not reflect the actual network conditions, can quickly lead to instability. This patch adds congestion-window validation (RFC2861) to CCID-2: * cwnd is constrained if the sender is application limited; * cwnd is reduced after a long idle period, as suggested in the '90 paper by Van Jacobson, in RFC 2581 (sec. 4.1); * cwnd is never reduced below the RFC 3390 initial window. As marked in the comments, the code is actually almost a direct copy of the TCP congestion-window-validation algorithms. By continuing this work, it may in future be possible to use the TCP code (not possible at the moment). The mechanism can be turned off using a module parameter. Sampling of the currently-used window (moving-maximum) is however done constantly; this is used to determine the expected window, which can be exploited to regulate DCCP's Sequence Window value. This patch also sets slow-start-after-idle (RFC 4341, 5.1), i.e. it behaves like TCP when net.ipv4.tcp_slow_start_after_idle = 1. Signed-off-by:Gerrit Renker <gerrit@erg.abdn.ac.uk>

This replaces a switch statement with a test, using the equivalent function dccp_data_packet(skb). It also doubles the range of the field `rx_num_data_pkts' by changing the type from `int' to `u32', avoiding signed/unsigned comparison with the u16 field `dccps_r_ack_ratio'. Signed-off-by: -

This patch rearranges the order of statements of the slow-path input processing (i.e. any other state than OPEN), to resolve the following issues. 1. Dependencies: the order of statements now better matches RFC 4340, 8.5, i.e. step 7 is before step 9 (previously 9 was before 7), and parsing options in step 8 (which may consume resources) now comes after step 7. 2. Sequence number checks are omitted if in state LISTEN/REQUEST, due to the note underneath the table in RFC 4340, 7.5.3. As a result, CCID processing is now indeed confined to OPEN/PARTOPEN states, i.e. congestion control is performed only on the flow of data packets. This avoids pathological cases of doing congestion control on those messages which set up and terminate the connection. 3. Packets are now passed on to Ack Vector / CCID processing only after - step 7 (receive unexpected packets), - step 9 (receive Reset), - step 13 (receive CloseReq), - step 14 (receive Close) and only if the state is PARTOPEN. This simplifies CCID processing: - in LISTEN/CLOSED the CCIDs are non-existent; - in RESPOND/REQUEST the CCIDs have not yet been negotiated; - in CLOSEREQ and active-CLOSING the node has already closed this socket; - in passive-CLOSING the client is waiting for its Reset. In the last case, RFC 4340, 8.3 leaves it open to ignore further incoming data, which is the approach taken here. Signed-off-by: -
