2011-08-02rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTERStephen Hemminger1-2/+2
When assigning a NULL value to an RCU protected pointer, no barrier is needed. The rcu_assign_pointer, used to handle that but will soon change to not handle the special case. Convert all rcu_assign_pointer of NULL value. //smpl @@ expression P; @@ - rcu_assign_pointer(P, NULL) + RCU_INIT_POINTER(P, NULL) // </smpl> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: Paul E.

2010-09-22netfilter: nf_nat: better error handling of nf_ct_expect_related() in helpersPablo Neira Ayuso1-1/+8
This patch improves the situation in which the expectation table is full for conntrack NAT helpers. Basically, we give up if we don't find a place in the table instead of looping over nf_ct_expect_related() with a different port (we should only do this if it returns -EBUSY, for -EMFILE or -ESHUTDOWN I think that it's better to skip this).
