* batman-adv: Use __func__ to add function names to messagesSven Eckelmann2017-03-171-3/+4
| | | | | | | | | The name of the function might change in which these messages are printed. It is therefore better to let the compiler handle the insertion of the correct function name. Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
* batman-adv: Fix includes for IS_ERR/ERR_PTRSven Eckelmann2017-01-281-1/+1
| | | | | | | | | IS_ERR/ERR_PTR are not defined in linux/device.h but in linux/err.h. The files using these macros therefore have to include the correct one.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>
| * batman-adv: Detect missing primaryif during tp_send as errorSven Eckelmann2016-11-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | The throughput meter detects different situations as problems for the current test. It stops the test after these and reports it to userspace. This also has to be done when the primary interface disappeared during the test.

* | batman-adv: Consume skb in batadv_send_skb_to_origSven Eckelmann2016-10-301-6/+0
|/ | | | | | | | | Sending functions in Linux consume the supplied skbuff. Doing the same in batadv_send_skb_to_orig avoids the hack of returning -1 (-EPERM) to signal the caller that he is responsible for cleaning up the skb.

* batman-adv: throughput meter implementationAntonio Quartulli2016-07-041-0/+1507
The throughput meter module is a simple, kernel-space replacement for throughtput measurements tool like iperf and netperf. It is intended to approximate TCP behaviour. It is invoked through batctl: the protocol is connection oriented, with cumulative acknowledgment and a dynamic-size sliding window. The test *can* be interrupted by batctl. A receiver side timeout avoids unlimited waitings for sender packets: after one second of inactivity, the receiver abort the ongoing test.
