TCA_HTB_DIRECT_QLEN attribute is supported since linux-3.10 HTB classes use an internal pfifo queue, which limit was not reported by tc, and value inherited from device tx_queue_len at setup time. With this patch, tc displays the value and can change it. Signed-off-by: Eric Dumazet <edumazet@google.com>

New command line flag to output statistics in JSON format. In our envrionment, we have scripts that parse output of commands. It is better to use a format supported by existing parsers.

This iproute2 tc patch is connected to the kernel - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling) The rate table calculated by tc, have gotten replaced in the kernel and is no-longer used for lookups. This happened in kernel release v3.8 caused by kernel - commit 56b765b79 ("htb: improved accuracy at high rates"). This change unfortunately caused breakage of tc overhead and linklayer parameters. Kernel overhead handling got fixed in kernel v3.10 by - commit 01cb71d2d47 (net_sched: restore "overhead xxx" handling) Kernel linklayer handling got fixed in kernel v3.11 by - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling) The linklayer fix introduced a struct change, that allow the linklayer attribute to be transferred between tc and kernel. This patch make use of this linklayer attribute. The linklayer setting is transfer to the kernel. And linklayer setting received from the kernel is printed with a prefixed "linklayer" when listing current configuration. The default TC_LINKLAYER_ETHERNET is only printed in detailed output mode.

Since commit a05f6511, ip batch mode is broken when using 'netns exec' cmd. When WIFEXITED() returns true, it means that the child exited normally, hence we must not call exit() but just returns the status. If we call exit, the next commands in the file file are not executed. If WIFEXITED() returns false, we can call exit() because it means that the child failed. This patch partially reverts commit a05f6511. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com>

The git-commit dc8867d0, that added support for displaying the extra-flags of a state, introduced a potential segfault. Trying to show a state without the extra-flag attribute and show_stats enabled, would cause the NULL pointer in tb[XFRMA_SA_EXTRA_FLAGS] to be dereferenced.

Add support for the bridge fdb replace command to replace an existing entry in the vxlan device driver forwarding data base. The entry is identified with its unicast mac address and its corresponding remote destination information is updated. This is useful for virtual machine migration and replaces the bridge fdb del and bridge fdb add commands. It follows the same interface as ip neigh replace commands.

When configuring a system with multiple network uplinks and default routes, it is often convenient to reference a routing table multiple times - but reject its routing decision if certain constraints are not met by it. Consider this setup: $ ip route add table secuplink default via 10.42.23.1 $ ip rule add pref 100 table main suppress_prefixlength 0 $ ip rule add pref 150 fwmark 0xA table secuplink With this setup, packets marked 0xA will be processed by the additional routing table "secuplink", but only if no suitable route in the main routing table can be found. By suppressing entries with a prefixlength of 0 (or less), the default route (/0) of the table "main" is hidden to packets processed by rule 100; packets traveling to destinations via more specific routes are processed as usual. It is also possible to suppress a routing entry if a device belonging to a specific interface group is to be used: $ ip rule add pref 150 table main suppress_group 1 Signed-off-by: Stefan Tomanek <stefan.tomanek@wertarbyte.de>
