Message-Id: <20101108.132636.246537518.davem@davemloft.net> Date: Mon, 08 Nov 2010 13:26:36 -0800 (PST) From: David Miller <davem@...emloft.net> To: jesse@...ira.com Cc: stable@...nel.org, netdev@...r.kernel.org Subject: Re: [PATCH 2.6.36 stable] vlan: Avoid hwaccel vlan packets when vid not used. From: Jesse Gross <jesse@...ira.com> Date: Mon, 8 Nov 2010 13:23:01 -0800 > Normally hardware accelerated vlan packets are quickly dropped if > there is no corresponding vlan device configured. The one exception > is promiscuous mode, where we allow all of these packets through so > they can be picked up by tcpdump. However, this behavior causes a > crash if we actually try to receive these packets. This fixes that > crash by ignoring packets with vids not corresponding to a configured > device in the vlan hwaccel routines and then dropping them before they > get to consumers in the network stack. > > This patch applies only to 2.6.36 stable. The problem was introduced > in that release and is already fixed by larger changes to the vlan > code in 2.6.37. > > Reported-by: Ben Greear <greearb@...delatech.com> > Tested-by: Nikola Ciprich <extmaillist@...uxbox.cz> > Signed-off-by: Jesse Gross <jesse@...ira.com> Acked-by: David S.
