2008-01-28[NETFILTER]: Use the ctl paths instead of hand-made analoguePavel Emelyanov1-3/+4
The conntracks subsystem has a similar infrastructure to maintain ctl_paths, but since we already have it on the generic level, I think it's OK to switch to using it. So, basically, this patch just replaces the ctl_table-s with ctl_path-s, nf_register_sysctl_table with register_sysctl_paths() and removes no longer needed code. After this the net/netfilter/nf_sysctl.c file contains the paths only. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2007-04-26[NETLINK]: Possible cleanups.Adrian Bunk1-1/+1
- make the following needlessly global variables static: - core/rtnetlink.c: struct rtnl_msg_handlers[] - netfilter/nf_conntrack_proto.c: struct nf_ct_protos[] - make the following needlessly global functions static: - core/rtnetlink.c: rtnl_dump_all() - netlink/af_netlink.c: netlink_queue_skip() Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[NETFILTER]: nf_conntrack: simplify l4 protocol array allocationPatrick McHardy1-25/+12
The retrying after an allocation failure is not necessary anymore since we're holding the mutex the entire time, for the same reason the double allocation race can't happen anymore. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[NETFILTER]: nf_conntrack: simplify protocol lockingPatrick McHardy1-31/+14
Now that we don't use nf_conntrack_lock anymore but a single mutex for all protocol handling, no need to release and grab it again for sysctl registration. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[NETFILTER]: nf_conntrack: remove ugly hack in l4proto registrationPatrick McHardy1-8/+26
Remove ugly special-casing of nf_conntrack_l4proto_generic, all it wants is its sysctl tables registered, so do that explicitly in an init function and move the remaining protocol initialization and cleanup code to nf_conntrack_proto.c as well. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[NETFILTER]: nf_conntrack: switch protocol registration/unregistration to mutexPatrick McHardy1-29/+23
The protocol lookups done by nf_conntrack are already protected by RCU, there is no need to keep taking nf_conntrack_lock for registration and unregistration. Switch to a mutex. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-02-12[NETFILTER]: nf_conntrack: change nf_conntrack_l[34]proto_unregister to voidPatrick McHardy1-33/+7
No caller checks the return value, and since its usually called within the module unload path there's nothing a module could do about errors anyway, so BUG on invalid conditions and return void. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-02-12[NETFILTER]: nf_conntrack: properly use RCU API for nf_ct_protos/nf_ct_l3protos arraysPatrick McHardy1-19/+14
Replace preempt_{enable,disable} based RCU by proper use of the RCU API and add missing rcu_read_lock/rcu_read_unlock calls in all paths not obviously only used within packet process context (nfnetlink_conntrack).

2006-12-02[NETFILTER]: nf_conntrack: EXPORT_SYMBOL cleanupPatrick McHardy1-0/+12
- move EXPORT_SYMBOL next to exported symbol - use EXPORT_SYMBOL_GPL since this is what the original code used Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[NETFILTER]: nf_conntrack: sysctl compatibility with old connection trackingPatrick McHardy1-0/+20
This patch adds an option to keep the connection tracking sysctls visible under their old names. Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: nf_conntrack: move conntrack protocol sysctls to individual modulesPatrick McHardy1-2/+10
Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: nf_conntrack: automatic sysctl registation for conntrack protocolsPatrick McHardy1-0/+102
Add helper functions for sysctl registration with optional instantiating of common path elements (like net/netfilter) and use it for support for automatic registation of conntrack protocol sysctls. Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: nf_conntrack: more sanity checks in protocol registration/unregistrationMartin Josefsson1-6/+49
Add some more sanity checks when registering/unregistering l3/l4 protocols. Signed-off-by: Martin Josefsson <gandalf@wlug.westbo.se> Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: nf_conntrack: rename struct nf_conntrack_protocolMartin Josefsson1-36/+36
Rename 'struct nf_conntrack_protocol' to 'struct nf_conntrack_l4proto' in order to help distinguish it from 'struct nf_conntrack_l3proto'. It gets rather confusing with 'nf_conntrack_protocol'. Signed-off-by: Martin Josefsson <gandalf@wlug.westbo.se> Signed-off-by: Patrick McHardy <kaber@trash.net>
2006-12-02[NETFILTER]: nf_conntrack: split out protocol handlingMartin Josefsson1-0/+225
This patch splits out L3/L4 protocol handling into its own file nf_conntrack_proto.c Signed-off-by: Martin Josefsson <gandalf@wlug.westbo.se> Signed-off-by: Patrick McHardy <kaber@trash.net>
