Message-Id: <20130320.121412.1230198756594408982.davem@davemloft.net> Date: Wed, 20 Mar 2013 12:14:12 -0400 (EDT) From: David Miller <davem@...emloft.net> To: tparkin@...alix.com Cc: netdev@...r.kernel.org Subject: Re: [PATCH 00/12] l2tp bugfix patchset From: Tom Parkin <tparkin@...alix.com> Date: Tue, 19 Mar 2013 16:11:11 +0000 > This l2tp bugfix patchset addresses a number of issues. > > The first five patches in the series prevent l2tp sessions pinning an l2tp > tunnel open. This occurs because the l2tp tunnel is torn down in the tunnel > socket destructor, but each session holds a tunnel socket reference which > prevents tunnels with sessions being deleted. The solution I've implemented > here involves adding a .destroy hook to udp code, as discussed previously on > netdev[1]. > > The subsequent seven patches address futher bugs exposed by fixing the problem > above, or exposed through stress testing the implementation above. Patch 11 > (avoid deadlock in l2tp stats update) isn't directly related to tunnel/session > lifetimes, but it does prevent deadlocks on i386 kernels running on 64 bit > hardware. > > This patchset has been tested on 32 and 64 bit preempt/non-preempt kernels, > using iproute2, openl2tp, and custom-made stress test code. > > [1] http://comments.gmane.org/gmane.linux.network/259169 All applied, thanks for fixing all of these bugs Tom. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
