* net: rtnetlink.h -- only include linux/netdevice.h when used by the kernelAndy Whitcroft2010-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit below added a new helper dev_ingress_queue to cleanly obtain the ingress queue pointer. This necessitated including 'linux/netdevice.h': commit 24824a09e35402b8d58dcc5be803a5ad3937bdba Author: Eric Dumazet <eric.dumazet@gmail.com> Date: Sat Oct 2 06:11:55 2010 +0000 net: dynamic ingress_queue allocation However this include triggers issues for applications in userspace which use the rtnetlink interfaces. Commonly this requires they include 'net/if.h' and 'linux/rtnetlink.h' leading to a compiler error as below: In file included from /usr/include/linux/netdevice.h:28:0, from /usr/include/linux/rtnetlink.h:9, from t.c:2: /usr/include/linux/if.h:135:8: error: redefinition of ‘struct ifmap’ /usr/include/net/if.h:112:8: note: originally defined here /usr/include/linux/if.h:169:8: error: redefinition of ‘struct ifreq’ /usr/include/net/if.h:127:8: note: originally defined here /usr/include/linux/if.h:218:8: error: redefinition of ‘struct ifconf’ /usr/include/net/if.h:177:8: note: originally defined here The new helper is only defined for the kernel and protected by __KERNEL__ therefore we can simply pull the include down into the same protected section.

* net: relax rtnl_dereference()David S. Miller2010-10-05
| | | | | | | | | | | | | | rtnl_dereference() is used in contexts where RTNL is held, to fetch an RCU protected pointer. Updates to this pointer are prevented by RTNL, so we dont need smp_read_barrier_depends() and the ACCESS_ONCE() provided in rcu_dereference_check(). rtnl_dereference() is mainly a macro to document the locking invariant.

* ipv6: ip6mr: support multiple tablesPatrick McHardy2010-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net>
* net: rtnetlink: decouple rtnetlink address families from real address familiesPatrick McHardy2010-04-26
| | | | | | | | | | | | | | | | | Decouple rtnetlink address families from real address families in socket.h to be able to add rtnetlink interfaces to code that is not a real address family without increasing AF_MAX/NPROTO. This will be used to add support for multicast route dumping from all tables as the proc interface can't be extended to support anything but the main table without breaking compatibility. This partialy undoes the patch to introduce independant families for routing rules and converts ipmr routing rules to a new rtnetlink family. Similar to that patch, values up to 127 are reserved for real address families, values above that may be used arbitrarily. Signed-off-by: Patrick McHardy <kaber@trash.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update rcu_dereference() primitives to use new lockdep-based checking. The rcu_dereference() in __in6_dev_get() may be protected either by rcu_read_lock() or RTNL, per Eric Dumazet. The rcu_dereference() in __sk_free() is protected by the fact that it is never reached if an update could change it. Check for this by using rcu_dereference_check() to verify that the struct sock's ->sk_wmem_alloc counter is zero. Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: David S.

* | net: Add rtnetlink init_rcvwnd to set the TCP initial receive windowlaurent chavey2009-12-23
|/ | | | | | | | | | | | | | | | | | | Add rtnetlink init_rcvwnd to set the TCP initial receive window size advertised by passive and active TCP connections. The current Linux TCP implementation limits the advertised TCP initial receive window to the one prescribed by slow start. For short lived TCP connections used for transaction type of traffic (i.e. http requests), bounding the advertised TCP initial receive window results in increased latency to complete the transaction. Support for setting initial congestion window is already supported using rtnetlink init_cwnd, but the feature is useless without the ability to set a larger TCP initial receive window. The rtnetlink init_rcvwnd allows increasing the TCP initial receive window, allowing TCP connection to advertise larger TCP receive window than the ones bounded by slow start.

* tcp: Revert per-route SACK/DSACK/TIMESTAMP changes.David S. Miller2009-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It creates a regression, triggering badness for SYN_RECV sockets, for example: [19148.022102] Badness at net/ipv4/inet_connection_sock.c:293 [19148.022570] NIP: c02a0914 LR: c02a0904 CTR: 00000000 [19148.023035] REGS: eeecbd30 TRAP: 0700 Not tainted (2.6.32) [19148.023496] MSR: 00029032 <EE,ME,CE,IR,DR> CR: 24002442 XER: 00000000 [19148.024012] TASK = eee9a820[1756] 'privoxy' THREAD: eeeca000 This is likely caused by the change in the 'estab' parameter passed to tcp_parse_options() when invoked by the functions in net/ipv4/tcp_minisocks.c But even if that is fixed, the ->conn_request() changes made in this patch series is fundamentally wrong. They try to use the listening socket's 'dst' to probe the route settings. The listening socket doesn't even have a route, and you can't get the right route (the child request one) until much later after we setup all of the state, and it must be done by hand. This stuff really isn't ready, so the best thing to do is a full revert.

* netlink: change nlmsg_notify() return value logicPablo Neira Ayuso2009-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

* [NET]: Introduce RTA_TABLE/FRA_TABLE attributesPatrick McHardy2006-09-22
| | | | | | | | | | | | Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute to hold 32 bit routing table IDs. Usespace compatibility is provided by continuing to accept and send the rtm_table field, but because of its limited size it can only carry the low 8 bits of the table ID. This implies that if larger IDs are used, _all_ userspace programs using them need to use RTA_TABLE. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
