[batctl] master: batctl: Allow to configure routing_algo during interface creation (07bacdf)
by postmaster＠open-mesh.org 09 Nov '20

09 Nov '20

Repository : ssh://git@diktynna/batctl On branch : master >--------------------------------------------------------------- commit 07bacdf37dc6d703346886a0b0955c4874dfd0bc Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Oct 11 13:09:50 2020 +0200 batctl: Allow to configure routing_algo during interface creation A batadv net_device is associated to a B.A.T.M.A.N. routing algorithm. This algorithm has to be selected before the interface is initialized and cannot be changed after that. The only way to select this algorithm was a module parameter which specifies the default algorithm used during the creation of the net_device. This module parameter is writeable over /sys/module/batman_adv/parameters/routing_algo and thus allows switching of the routing algorithm: 1. change routing_algo parameter 2. create new batadv net_device But this is not race free because another process can be scheduled between 1 + 2 and in that time frame change the routing_algo parameter again. It is much cleaner to directly provide this information inside the rtnetlink's RTM_NEWLINK message. The two processes would be (in regards of the creation parameter of their batadv interfaces) be isolated. This can now be done (with a compatible kernel module) using the routing_algo parameter of interface create: $ batctl meshif bat0 interface create routing_algo BATMAN_IV or $ batctl meshif bat0 interface create routing_algo BATMAN_V Signed-off-by: Sven Eckelmann <sven(a)narfation.org> >--------------------------------------------------------------- 07bacdf37dc6d703346886a0b0955c4874dfd0bc batman_adv.h | 26 +++++++++++++++++++++++ interface.c | 69 +++++++++++++++++++++++++++++++++++++++++++++++++++++++----- man/batctl.8 | 8 ++++--- 3 files changed, 95 insertions(+), 8 deletions(-) diff --git a/batman_adv.h b/batman_adv.h index bb0ae94..bdb317f 100644 --- a/batman_adv.h +++ b/batman_adv.h @@ -675,4 +675,30 @@ enum batadv_tp_meter_reason { BATADV_TP_REASON_TOO_MANY = 133, };
