Date: Wed, 17 Jun 2015 15:27:42 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Cong Wang <amwang@...hat.com>, Stephen Hemminger <stephen@...workplumber.org>, bridge@...ts.linux-foundation.org, Nicolas Dichtel <nicolas.dichtel@...nd.com>, "David S. Miller" <davem@...emloft.net>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.13.y-ckt 035/122] bridge/mdb: remove wrong use of NLM_F_MULTI 3.13.11-ckt22 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Nicolas Dichtel <nicolas.dichtel@...nd.com> commit 821996795973fd52703c35811a03db9fec1ac141 upstream. NLM_F_MULTI must be used only when a NLMSG_DONE message is sent. In fact, it is sent only at the end of a dump. Libraries like libnl will wait forever for NLMSG_DONE.
