Date: Thu, 16 Nov 2017 10:50:03 +0900 (KST) From: David Miller <davem@...emloft.net> To: mkubecek@...e.cz Cc: johannes@...solutions.net, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: Re: [PATCH net] genetlink: fix genlmsg_nlhdr() From: Michal Kubecek <mkubecek@...e.cz> Date: Wed, 15 Nov 2017 13:09:32 +0100 (CET) > According to the description, first argument of genlmsg_nlhdr() points to > what genlmsg_put() returns, i.e. beginning of user header. Therefore we > should only subtract size of genetlink header and netlink message header, > not user header. > > This also means we don't need to pass the pointer to genetlink family and > the same is true for genl_dump_check_consistent() which is the only caller > of genlmsg_nlhdr(). (Note that at the moment, these functions are only > used for families which do not have user header so that they are not > affected.) > > Fixes: 670dc2833d14 ("netlink: advertise incomplete dumps") > Signed-off-by: Michal Kubecek <mkubecek@...e.cz> Applied.
