* tc: propogate errors from tcf_hash_createStephen Hemminger2008-11-258-19/+27
| | | | | | | Allow tcf_hash_create to return different errors on estimator failure. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* netns xfrm: per-netns sysctlsAlexey Dobriyan2008-11-256-56/+105
| | | | | | | | | | | | | | | | | Make net.core.xfrm_aevent_etime net.core.xfrm_acq_expires net.core.xfrm_aevent_rseqth net.core.xfrm_larval_drop sysctls per-netns. For that make net_core_path[] global, register it to prevent two /proc/net/core antries and change initcall position -- xfrm_init() is called from fs_initcall, so this one should be fs_initcall at least.

| | | | | | | | | | * interaction with userspace -- take netns from userspace socket. * in ->notify hook take netns either from SA or explicitly passed -- we don't know if SA/SPD flush is coming. * stub policy migration with init_net for now.
