net: implement IP_RECVTOS for IP_PKTOPTIONS

2012-02-13T05:46:41Z

Currently, it is not easily possible to get TOS/DSCP value of packets from an incoming TCP stream. The mechanism is there, IP_PKTOPTIONS getsockopt with IP_RECVTOS set, the same way as incoming TTL can be queried. This is not actually implemented for TOS, though. This patch adds this functionality, both for IPv4 (IP_PKTOPTIONS) and IPv6 (IPV6_2292PKTOPTIONS). For IPv4, like in the IP_RECVTTL case, the value of the TOS field is stored from the other party's ACK. This is needed for proxies which require DSCP transparency.

ipv6: mcast: RCU conversion

2010-11-24T19:16:42Z

ipv6_sk_mc_lock rwlock becomes a spinlock. readers (inet6_mc_check()) now takes rcu_read_lock() instead of read lock. Writers dont need to disable BH anymore. struct ipv6_mc_socklist objects are reclaimed after one RCU grace period. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

header: fix broken headers for user space

2010-08-23T04:15:39Z

__packed is only defined in kernel space, so we should use __attribute__((packed)) for the code shared between kernel and user space. Two __attribute() annotations are replaced with __attribute__() too. Signed-off-by: Changli Gao Signed-off-by: David S. Miller

ipv6: Make IP6CB(skb)->nhoff 16-bit.

2010-07-20T05:01:26Z

Even with jumbograms I cannot see any way in which we would need to records a larger than 65535 valued next-header offset. The maximum extension header length is (256 << 3) == 2048. There are only a handful of extension headers specified which we'd even accept (say 5 or 6), therefore the largest next-header offset we'd ever have to contend with is something less than say 16k. Therefore make it a u16 instead of a u32. Signed-off-by: David S. Miller

ipv6: ip6mr: support multiple tables

2010-05-11T12:40:55Z

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
