The kernel supports a link mode attribute (which can be dormant or default). This attribute is used to control how the link watch engine handles operstate transistion. This adds a new parameter to ip link command to allow setting and displaying the value. ---

There is nothing in the standard that says 0 can't be used as a key. It makes sense to allow it. Also fix typo where ikey was printed for when printing okey.

As reported by Thomas Mühlgrabner <muehltom@cable.vol.at> in http://bugs.debian.org/662979 : When showing htb class configuration with "tc -iec class show", the output for Mibit is actually the value for bit. Example: configure a class with a ceil of 1000Mibit. Output states 1048576000 Mibit. The cause is missing parenteses in the display code of tc.... (Please also note that a lower value of 100Mibit will be displayed as 102400 Kibit, which I think is kind of ugly.)

On 64 bit platform, casting to unsigned long long is unnecessary. Use inttypes.h and stdtypes.h to resolve it.

A new option -p is added to the arpd command that accepts a time indicating the number of seconds to wait between kernel arp table polling attempts. The minimum value is .1 (100ms). If not specified, polling defaults to 30 seconds. Patch by Erik Hugne <erik.hugne@ericsson.com> with modifications

Based on patch by Vasiliy Kulikov <segoon@openwall.com> Don't use /tmp since it is dangerous, instead put temporary files from configure script in build directory. This is what autoconf generated configure does.

(Resending patch since it looks like my earlier mail did not make it to netdev). netem reordering requires that the delay parameter be given. Currently, if no delay is given, tc prints the error message but still installs the qdisc. Fix this by printing the usage and failing cleanly.

Adds an optional Random Early Detection on each SFQ flow queue. Traditional SFQ limits count of packets, while RED permits to also control number of bytes per flow, and adds ECN capability as well. 1) We dont handle the idle time management in this RED implementation, since each 'new flow' begins with a null qavg. We really want to address backlogged flows. 2) if headdrop is selected, we try to ecn mark first packet instead of currently enqueued packet. This gives faster feedback for tcp flows compared to traditional RED [ marking the last packet in queue ] Example of use : tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 4sec sfq \ limit 3000 headdrop flows 512 divisor 16384 \ redflowlimit 100000 min 8000 max 60000 probability 0.20 ecn qdisc sfq 10: parent 1:1 limit 3000p quantum 1514b depth 127 headdrop flows 512/16384 divisor 16384 ewma 6 min 8000b max 60000b probability 0.2 ecn prob_mark 0 prob_mark_head 4876 prob_drop 6131 forced_mark 0 forced_mark_head 0 forced_drop 0 Sent 1175211782 bytes 777537 pkt (dropped 6131, overlimits 11007 requeues 0) rate 99483Kbit 8219pps backlog 689392b 456p requeues 0 In this test, with 64 netperf TCP_STREAM sessions, 50% using ECN enabled flows, we can see number of packets CE marked is smaller than number of drops (for non ECN flows) If same test is run, without RED, we can check backlog is much bigger. qdisc sfq 10: parent 1:1 limit 3000p quantum 1514b depth 127 headdrop flows 512/16384 divisor 16384 Sent 1148683617 bytes 795006 pkt (dropped 0, overlimits 0 requeues 0) rate 98429Kbit 8521pps backlog 1221290b 841p requeues 0 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com>
