Rules which match against device names in their selector can remain while the device itself disappears, in fact the device doesn't have to present when the rule is added in the first place. The device name is resolved by trying when the rule is added and later by listening to NETDEV_REGISTER/UNREGISTER notifications. This patch adds the flag FIB_RULE_DEV_DETACHED which is set towards userspace when a rule contains a device match which is unresolved at the moment. This eases spotting the reason why certain rules seem not to function properly. Signed-off-by:

This patch adds a new rule action FR_ACT_GOTO which allows to skip a set of rules by jumping to another rule. The rule to jump to is specified via the FRA_GOTO attribute which carries a rule preference. Referring to a rule which doesn't exists is explicitely allowed. Such goto rules are marked with the flag FIB_RULE_UNRESOLVED and will act like a rule with a non-matching selector. The rule will become functional as soon as its target is present. The goto action enables performance optimizations by reducing the average number of rules that have to be passed per lookup. Example: 0: from all lookup local 40: not from all to 192.168.23.128 goto 32766 41: from all fwmark 0xa blackhole 42: from all fwmark 0xff blackhole 32766: from all lookup main Signed-off-by:

The following update received from Injong updates TCP cubic to the latest version. I am running more complete tests and will have results after 4/1. According to Injong: the new version improves on its scalability, fairness and stability. So in all properties, we confirmed it shows better performance. NCSU results (for 2.6.18 and 2.6.20) available: http://netsrv.csc.ncsu.edu/wiki/index.php/TCP_Testing This version is described in a new Internet draft for CUBIC. http://www.ietf.org/internet-drafts/draft-rhee-tcp-cubic-00.txtSigned-off-by:

The days are gone when this was not an issue, there are folks out there with huge bot networks that can be used to attack the established hash tables on remote systems. So just like the routing cache and connection tracking hash, use Jenkins hash with random secret input. Signed-off-by: -

This patch introduces a new NLA_BINARY attribute policy type with the verification of simply checking the maximum length of the payload. It also fixes a small typo in the example. Signed-off-by:

As stated in the sctp socket api draft: sac_info: variable If the sac_state is SCTP_COMM_LOST and an ABORT chunk was received for this association, sac_info[] contains the complete ABORT chunk as defined in the SCTP specification RFC2960 [RFC2960] section 3.3.7. We now save received ABORT chunks into the sac_info field and pass that to the user. Signed-off-by:

Parameters only take effect when a corresponding flag bit is set and a value is specified. This means we need to check the flags in addition to checking for non-zero value. Signed-off-by:

This option induces partial delivery to run as soon as the specified amount of data has been accumulated on the association. However, we give preference to fully reassembled messages over PD messages. In any case, window and buffer is freed up. Signed-off-by:

This option was introduced in draft-ietf-tsvwg-sctpsocket-13. It prevents head-of-line blocking in the case of one-to-many endpoint. Applications enabling this option really must enable SCTP_SNDRCV event so that they would know where the data belongs. Based on an earlier patch by Ivan Skytte Jørgensen. Additionally, this functionality now permits multiple associations on the same endpoint to enter Partial Delivery. Applications should be extra careful, when using this functionality, to track EOR indicators. Signed-off-by:

netem checks PSCHED_TLESS(cb->time_to_send, now) to find out whether it is allowed to send a packet, which is equivalent to cb->time_to_send < now. Use !PSCHED_TLESS(now, cb->time_to_send) instead to properly handle cb->time_to_send == now. Signed-off-by:

Patrick has made use of netlink_run_queue() in nfnetlink while my patches have been waiting for net-2.6.22 to open. So this check for NLM_F_REQUEST can go as well. 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:

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:
