2006-09-22[NET/IPV4/IPV6]: Change some sysctl variables to __read_mostlyBrian Haley
Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly. Couldn't actually measure any performance increase while testing (.3% I consider noise), but seems like the right thing to do. Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-22[RTNETLINK]: Add rtnetlink notification interfaceThomas Graf
Adds rtnl_notify() to send rtnetlink notification messages and rtnl_set_sk_err() to report notification errors as socket errors in order to indicate the need of a resync due to loss of events. nlmsg_report() is added to properly document the meaning of NLM_F_ECHO.

2006-09-22[NETLINK]: Add notification message sending interfaceThomas Graf
Adds nlmsg_notify() implementing proper notification logic. The message is multicasted to all listeners in the group. The applications the requests orignates from can request a unicast back report in which case said socket will be excluded from the multicast to avoid duplicated notifications. nlmsg_multicast() is extended to take allocation flags to allow notification in atomic contexts.

2006-09-22[NET] netdev: Check name lengthStephen Hemminger

2006-09-22[HTB]: rbtree cleanupStephen Hemminger

Miller <davem@davemloft.net>
2006-09-22[HTB]: Use hlist for hash lists.Stephen Hemminger
Use hlist instead of list for the hash list. This saves space, and we can check for double delete better. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[HTB]: LindentStephen Hemminger

2006-09-22[DECNET]: Increase number of possible routing tables to 2^32Patrick McHardy

2006-09-22[NET]: Introduce RTA_TABLE/FRA_TABLE attributesPatrick McHardy
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. Miller <davem@davemloft.net>
2006-09-22[NET]: Use u32 for routing table IDsPatrick McHardy
Use u32 for routing table IDs in net/ipv4 and net/decnet in preparation of support for a larger number of routing tables. net/ipv6 already uses u32 everywhere and needs no further changes. No functional changes are made by this patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-22[NET]: sock_register interface changesStephen Hemminger
The sock_register() doesn't change the family, so the protocols can define it read-only. No caller ever checks return value from sock_unregister() Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[NET]: socket family using RCUStephen Hemminger

2006-09-22[DECNET]: Covert rules to use generic codeSteven Whitehouse

2006-09-22[IPV4]: Use network-order dport for all visible inet_lookup_*Herbert Xu
Right now most inet_lookup_* functions take a host-order hnum instead of a network-order dport because that's how it is represented internally. This means that users of these functions have to be careful about using the right byte-order. To add more confusion, inet_lookup takes a network-order dport unlike all other functions. So this patch changes all visible inet_lookup functions to take a dport and move all dport->hnum conversion inside them.

2006-09-22[IPV4] fib: convert reader/writer to spinlockStephen Hemminger
Ther is no point in using a more expensive reader/writer lock for a low contention lock like the fib_info_lock. The only reader case is in handling route redirects. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[IPV6]: Make sure fib6_rule_lookup doesn't return NULLVille Nuorvala
The callers of fib6_rule_lookup don't expect it to return NULL, therefore it must return ip6_null_entry whenever fib_rule_lookup fails. Signed-off-by: Ville Nuorvala <vnuorval@tcs.hut.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[IPV4]: Uninline inet_lookup_listenerHerbert Xu
By modern standards this function is way too big to be inlined. It's even bigger than __inet_lookup_listener :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[INET]: Remove is_setbyuser patchLouis Nyffenegger
The value is_setbyuser from struct ip_options is never used and set only one time (http://linux-net.osdl.org/index.php/TODO#IPV4). This little patch removes it from the kernel source. Signed-off-by: Louis Nyffenegger <louis.nyffenegger@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
