ip: introduce ip_is_fragment helper inline function

2011-06-22T03:33:34Z

There are enough instances of this: iph->frag_off & htons(IP_MF | IP_OFFSET) that a helper function is probably warranted. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

inet: constify ip headers and in6_addr

2011-04-22T18:04:14Z

Add const qualifiers to structs iphdr, ipv6hdr and in6_addr pointers where possible, to make code intention more obvious. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

netfilter: fix Kconfig dependencies

2011-01-14T12:36:42Z

Fix dependencies of netfilter realm match: it depends on NET_CLS_ROUTE, which itself depends on NET_SCHED; this dependency is missing from netfilter. Since matching on realms is also useful without having NET_SCHED enabled and the option really only controls whether the tclassid member is included in route and dst entries, rename the config option to IP_ROUTE_CLASSID and move it outside of traffic scheduling context to get rid of the NET_SCHED dependeny.

net: use this_cpu_ptr()

2010-06-29T06:24:29Z

use this_cpu_ptr(p) instead of per_cpu_ptr(p, smp_processor_id()) Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net-next: remove useless union keyword

2010-06-11T06:31:35Z

remove useless union keyword in rtable, rt6_info and dn_route. Since there is only one member in a union, the union keyword isn't useful. Signed-off-by: Changli Gao Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: avoid two atomic ops in ip_rcv_options()

2010-06-08T04:49:51Z

in_dev_get() -> __in_dev_get_rcu() in a rcu protected function. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ip: Router Alert RCU conversion

2010-06-08T04:25:21Z

Straightforward conversion to RCU. One rwlock becomes a spinlock, and is static. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipv4: add LINUX_MIB_IPRPFILTER snmp counter

2010-06-03T10:18:19Z

Christoph Lameter mentioned that packets could be dropped in input path because of rp_filter settings, without any SNMP counter being incremented. System administrator can have a hard time to track the problem. This patch introduces a new counter, LINUX_MIB_IPRPFILTER, incremented each time we drop a packet because Reverse Path Filter triggers. (We receive an IPv4 datagram on a given interface, and find the route to send an answer would use another interface) netstat -s | grep IPReversePathFilter IPReversePathFilter: 21714 Reported-by: Christoph Lameter Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: Use ip_route_input_noref() in input path

2010-05-18T00:18:51Z

Use ip_route_input_noref() in ip fast path, to avoid two atomic ops per incoming packet. Note: loopback is excluded from this optimization in ip_rcv_finish() Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
