This avoids a (harmless) warning message being printed at the DCCP server (the receiver of a DCCP half connection). Incoming packets are both directed to * ccid_hc_rx_packet_recv() for the server half * ccid_hc_tx_packet_recv() for the client half The message gets printed since on a server the client half is currently not sending data packets. This is resolved for the moment by checking the DCCP-role first. In future times (bidirectional DCCP connections), this test may have to be more sophisticated. Signed-off-by:

The main object of this patch is the following bug: ==> In ccid3_hc_tx_packet_recv, the parameters p and X_recv were updated _after_ the send rate was calculated. This is clearly an error and is resolved by re-ordering statements. In addition, * r_sample is converted from u32 to long to check whether the time difference was negative (it would otherwise be converted to a large u32 value) * protection against RTT=0 (this is possible) is provided in a further patch * t_elapsed is also converted to long, to match the type of r_sample * adds a a more debugging information regarding current send rates * various trivial comment/documentation updates Signed-off-by: -

This bug resulted in ccid3_hc_tx_send_packet returning negative delay values, which in turn triggered silently dequeueing packets in dccp_write_xmit. As a result, only a few out of the submitted packets made it at all onto the network. Occasionally, when dccp_wait_for_ccid was involved, this also triggered a bug warning since ccid3_hc_tx_send_packet returned a negative value (which in reality was a negative delay value). The cause for this bug lies in the comparison if (delay >= hctx->ccid3hctx_delta) return delay / 1000L; The type of `delay' is `long', that of ccid3hctx_delta is `u32'. When comparing negative long values against u32 values, the test returned `true' whenever delay was smaller than 0 (meaning the packet was overdue to send). The fix is by casting, subtracting, and then testing the difference with regard to 0. This has been tested and shown to work. Signed-off-by:

The TFRC nofeedback timer normally expires after the maximum of 4 RTTs and twice the current send interval (RFC 3448, 4.3). On LANs with a small RTT this can mean a high processing load and reduced performance, since then the nofeedback timer is triggered very frequently. This patch provides a configuration option to set the bound for the nofeedback timer, using as default 100 milliseconds. By setting the configuration option to 0, strict RFC 3448 behaviour can be enforced for the nofeedback timer. Signed-off-by:

aevents can not uniquely identify an SA. We break the ABI with this patch, but consensus is that since it is not yet utilized by any (known) application then it is fine (better do it now than later). Signed-off-by:

Some helpers (namely H.323) manually assign further helpers to expected connections. This is not possible with nf_conntrack anymore since we need to know whether a helper is used at allocation time. Handle the helper assignment centrally, which allows to perform the correct allocation and as a nice side effect eliminates the need for the H.323 helper to fiddle with nf_conntrack_lock. Mid term the allocation scheme really needs to be redesigned since we do both the helper and expectation lookup _twice_ for every new connection. Signed-off-by:

We really can't remove ip_queue. Many users use this, there is no binary compatible interface and even the compat replacement for the originally statically linked library doesn't work. There is also no real necessity to remove the code, so the feature-removal-schedule entry should be removed instead. Signed-off-by: -

The tc actions increased the size of struct tc_police, which broke compatibility with old iproute binaries since both the act_police and the old NET_CLS_POLICE code check for an exact size match. Since the new members are not even used, the simple fix is to also accept the size of the old structure. Dumping is not affected since old userspace will receive a bigger structure, which is handled fine. Signed-off-by:
