Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2017-02-01 1) Some typo fixes, from Alexander Alemayhu. 2) Don't acquire state lock in get_mtu functions. The only rece against a dead state does not matter. From Florian Westphal. 3) Remove xfrm4_state_fini, it is unused for more than 10 years. From Florian Westphal. 4) Various rcu usage improvements. From Florian Westphal. 5) Properly handle crypto arrors in ah4/ah6. From Gilad Ben-Yossef. 6) Try to avoid skb linearization in esp4 and esp6. 7) The esp trailer is now set up in different places, add a helper for this. 8) With the upcomming usage of gro_cells in IPsec, a gro merged skb can have a secpath. Drop it before freeing or reusing the skb. 9) Add a xfrm dummy network device for napi. With this we can use gro_cells from within xfrm, it allows IPsec GRO without impact on the generic networking code. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

thread+0x48/0x4d0 kthread+0x101/0x140 and this patch purely papers over the issue by adding a NULL pointer check and a WARN_ON_ONCE() to avoid the oops that would then generally make the machine unresponsive. Other callers of i915_gem_object_to_ggtt() seem to also check for the returned pointer being NULL and warn about it, so this clearly has happened before in other places. [ Reported it originally to the i915 developers on Jan 8, applying the ugly workaround on my own now after triggering the problem for the second time with no feedback. This is likely to be the same bug reported as https://bugs.freedesktop.org/show_bug.cgi?id=98829 https://bugs.freedesktop.org/show_bug.cgi?id=99134 which has a patch for the underlying problem, but it hasn't gotten to me, so I'm applying the workaround. ] Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
