* genetlink: export genl_unregister_mc_group()Inaky Perez-Gonzalez2009-01-07
| | | | | | | | | | | | | | | | | | | | Add an EXPORT_SYMBOL() to genl_unregister_mc_group(), to allow unregistering groups on the run. EXPORT_SYMBOL_GPL() is not used as the rest of the functions exported by this module (eg: genl_register_mc_group) are also not _GPL(). Cleanup is currently done when unregistering a family, but there is no way to unregister a single multicast group due to that function not being exported. Seems to be a mistake as it is documented as for external consumption. This is needed by the WiMAX stack to be able to cleanup unused mc groups.

* netlink: allow empty nested attributesPatrick McHardy2008-11-28
| | | | | | | | | | | | | validate_nla() currently doesn't allow empty nested attributes. This makes userspace code unnecessarily complicated when starting and ending the nested attribute is done by generic upper level code and the inner attributes are dumped by a module. Add a special case to accept empty nested attributes. When the nested attribute is non empty, the same checks as before are performed.

* net: Make sure BHs are disabled in sock_prot_inuse_add()David S. Miller2008-11-23

* net: convert BUG_TRAP to generic WARN_ONIlpo Järvinen2008-07-26
| | | | | | | | | | | | | | Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | genetlink has a circular locking dependency when dumping the registered families: - dump start: genl_rcv() : take genl_mutex genl_rcv_msg() : call netlink_dump_start() while holding genl_mutex netlink_dump_start(), netlink_dump() : take nlk->cb_mutex ctrl_dumpfamily() : try to detect this case and not take genl_mutex a second time - dump continuance: netlink_rcv() : call netlink_dump netlink_dump : take nlk->cb_mutex ctrl_dumpfamily() : take genl_mutex Register genl_lock as callback mutex with netlink to fix this. This slightly widens an already existing module unload race, the genl ops used during the dump might go away when the module is unloaded. Thomas Graf is working on a seperate fix for this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The comment about "race free view of the set of network namespaces" was a bit hasty. Look (there even can be only one CPU, as discovered by Alexey Dobriyan and Denis Lunev): put_net() if (atomic_dec_and_test(&net->refcnt)) /* true */ __put_net(net); queue_work(...); /* * note: the net now has refcnt 0, but still in * the global list of net namespaces */ == re-schedule == register_pernet_subsys(&some_ops); register_pernet_operations(&some_ops); (*some_ops)->init(net); /* * we call netlink_kernel_create() here * in some places */ netlink_kernel_create(); sk_alloc(); get_net(net); /* refcnt = 1 */ /* * now we drop the net refcount not to * block the net namespace exit in the * future (or this can be done on the * error path) */ put_net(sk->sk_net); if (atomic_dec_and_test(&...)) /* * true. BOOOM! The net is * scheduled for release twice */ When thinking on this problem, I decided, that getting and putting the net in init callback is wrong. If some init callback needs to have a refcount-less reference on the struct net, _it_ has to be careful himself, rather than relying on the infrastructure to handle this correctly. In case of netlink_kernel_create(), the problem is that the sk_alloc() gets the given namespace, but passing the info that we don't want to get it inside this call is too heavy. Instead, I propose to crate the socket inside an init_net namespace and then re-attach it to the desired one right after the socket is created. After doing this, we also have to be careful on error paths not to drop the reference on the namespace, we didn't get the one on.

* [NETNS]: Namespace stop vs 'ip r l' race.Denis V. Lunev2008-01-28
| | | | | | | | | | | | | | | | | | | | During network namespace stop process kernel side netlink sockets belonging to a namespace should be closed. They should not prevent namespace to stop, so they do not increment namespace usage counter. Though this counter will be put during last sock_put. The raplacement of the correct netns for init_ns solves the problem only partial as socket to be stoped until proper stop is a valid netlink kernel socket and can be looked up by the user processes. This is not a problem until it resides in initial namespace (no processes inside this net), but this is not true for init_net. So, hold the referrence for a socket, remove it from lookup tables and only after that change namespace and perform a last put. Signed-off-by: Denis V.

So marking struct pernet_operations is a disaster for modules in two ways. - We discard it before we call the exit method it points to. - Because I keep struct pernet_operations on a linked list discarding it for compiled in code removes elements in the middle of a linked list and does horrible things for linked insert.

* [NET]: make netlink user -> kernel interface synchroniousDenis V. Lunev2007-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch make processing netlink user -> kernel messages synchronious. This change was inspired by the talk with Alexey Kuznetsov about current netlink messages processing. He says that he was badly wrong when introduced asynchronious user -> kernel communication. The call netlink_unicast is the only path to send message to the kernel netlink socket. But, unfortunately, it is also used to send data to the user. Before this change the user message has been attached to the socket queue and sk->sk_data_ready was called. The process has been blocked until all pending messages were processed. The bad thing is that this processing may occur in the arbitrary process context. This patch changes nlk->data_ready callback to get 1 skb and force packet processing right in the netlink_unicast. Kernel -> user path in netlink_unicast remains untouched. EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock drop, but the process remains in the cycle until the message will be fully processed. So, there is no need to use this kludges now. Signed-off-by: Denis V.
