* cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits: netRusty Russell2008-12-291-2/+2
| | | | | | | | | | | | | | In future all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in iterators and other comparisons. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.

| | * | netfilter: ctnetlink: deliver events for conntracks changed from userspacePablo Neira Ayuso2008-11-184-29/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As for now, the creation and update of conntracks via ctnetlink do not propagate an event to userspace. This can result in inconsistent situations if several userspace processes modify the connection tracking table by means of ctnetlink at the same time. Specifically, using the conntrack command line tool and conntrackd at the same time can trigger unconsistencies. This patch also modifies the event cache infrastructure to pass the process PID and the ECHO flag to nfnetlink_send() to report back to userspace if the process that triggered the change needs so.

For the explicit case, we try to load the module. If the module is correctly loaded and the helper is present, we return EAGAIN to re-start the creation. Otherwise, we return EOPNOTSUPP. * Update path: release the spin lock, load the module and check. If it is present, then return EAGAIN to re-start the update. This patch provides a refactorized function to lookup-and-set the connection tracking helper. The function removes the exported symbol __nf_ct_helper_find as it has not clients anymore.

|/ | | | | | | | | | | | | | | | register_pernet_gen_device() can't be used is nf_conntrack_pptp module is also used (compiled in or loaded). Right now, proto_gre_net_exit() is called before nf_conntrack_pptp_net_exit(). The former shutdowns and frees GRE piece of netns, however the latter absolutely needs it to flush keymap. Oops is inevitable. Switch to shiny new register_pernet_gen_subsys() to get correct ordering in netns ops list.
