We don't need local nlbufsiz (skb size) as nfulnl_alloc_skb() takes the maximum anyway. Signed-off-by:

Now that all users of netlink_dump_start() use netlink_run_queue() to process the receive queue, it is possible to return -EINTR from netlink_dump_start() directly, therefore simplying the callers. Signed-off-by:

Makes use of netlink_run_queue() to process the receive queue and converts inet_diag_rcv_msg() to use the type safe netlink interface. Signed-off-by:
-
Thomas Graf authored
The error pointer argument in netlink message handlers is used to signal the special case where processing has to be interrupted because a dump was started but no error happened. Instead it is simpler and more clear to return -EINTR and have netlink_run_queue() deal with getting the queue right. nfnetlink passed on this error pointer to its subsystem handlers but only uses it to signal the start of a netlink dump. Therefore it can be removed there as well. This patch also cleans up the error handling in the affected message handlers to be consistent since it had to be touched anyway. Signed-off-by:

Changes netlink_rcv_skb() to skip netlink controll messages and don't pass them on to the message handler. Signed-off-by:

Thomas Graf authored
netlink_rcv_skb() is changed to skip messages which don't have the NLM_F_REQUEST bit to avoid every netlink family having to perform this check on their own. Signed-off-by:

If possible, avoid having to do a transmit softirq when a qdisc watchdog decides to re-enable. The watchdog routine runs off a timer, so it is already in the same effective context as the softirq. Signed-off-by:

The netem code would call getnstimeofday() and dequeue/requeue after every packet, even if it was waiting. Avoid this overhead by using the throttled flag. Signed-off-by:

In most cases, the next packet will be sent after the last one. So optimize that case. Signed-off-by:

The random number generator always generates 32 bit values. The time values are limited by psched_tdiff_t Signed-off-by:

If you setup netem to just delay packets; "tc qdisc ls" will report the reordering as 100%. Well it's a lie, reorder isn't used unless gap is set, so just set value to 0 so the output of utility is correct. Signed-off-by:

Minor optimization of div64_64. do_div() already does optimization for the case of 32 by 32 divide, so no need to do it here. Signed-off-by:

Implements a unified, protocol independant rules dumping function which is capable of both, dumping a specific protocol family or all of them. This speeds up dumping as less lookups are required. Signed-off-by:

This patch adds a new interface to register rtnetlink message handlers replacing the exported rtnl_links[] array which required many message handlers to be exported unnecessarly. Signed-off-by:
-
Gerrit Renker authored
The patch follows the following recommendation made in an erratum to RFC 4342: "Senders MAY additionally make use of other available RTT measurements, including those from the initial Request-Response packet exchange." It implements larger initial windows with regard to this inital RTT measurement, using the mechanism suggested in draft-ietf-dccp-rfc3448bis, section 4.2. Signed-off-by:

This replaces the existing occurrences of RTT sampling with the use of the new function dccp_sample_rtt. Signed-off-by:
-
Gerrit Renker authored
A recurring problem, in particular in the CCID code, is that RTT samples from packets with timestamp echo and elapsed time options need to be taken. This service is provided via a new function dccp_sample_rtt in this patch. Furthermore, to protect against `insane' RTT samples, the sampled value is bounded between 100 microseconds and 4 seconds - for which u32 is sufficient. Signed-off-by:

This updates the code with regard to handling idle and application-limited periods as specified in [RFC 4342, 5.1]. Background:
-
Gerrit Renker authored
The CCID 3 and TFRC specs (RFC 4342, RFC 3448, draft-3448bis) make frequent reference to the computation of the RFC-3390 initial sending rate: 1. Initial sending rate when RTT is known (RFC 4342, p. 6) 2. Response to Idle/Application-Limited periods (RFC 4342, 5.1) This warrants putting the code into its own function, for later code reuse.
