Patrick McHardy 4498121ca3 [NET]: Handle disabled preemption in gfp_any() ... ctnetlink uses netlink_unicast from an atomic_notifier_chain (which is called within a RCU read side critical section) without holding further locks. netlink_unicast calls netlink_trim with the result of gfp_any() for the gfp flags, which are passed down to pskb_expand_header. gfp_any() only checks for softirq context and returns GFP_KERNEL, resulting in this warning: BUG: sleeping function called from invalid context at mm/slab.c:3032 in_atomic():1, irqs_disabled():0 no locks held by rmmod/7010.

Additionally nfnetlink_send needs to use gfp_any() as well for the call to netlink_broadcast). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
