ipv6: updates to privacy addresses per RFC 4941.

2011-08-02T01:05:00Z

Update the code to handle some of the differences between RFC 3041 and RFC 4941, which obsoletes it. Also a couple of janitorial fixes. - Allow router advertisements to increase the lifetime of temporary addresses. This was not allowed by RFC 3041, but is specified by RFC 4941. It is useful when RA lifetimes are lower than TEMP_{VALID,PREFERRED}_LIFETIME: in this case, the previous code would delete or deprecate addresses prematurely. - Change the default of MAX_RETRY to 3 per RFC 4941. - Add a comment to clarify that the preferred and valid lifetimes in inet6_ifaddr are relative to the timestamp. - Shorten lines to 80 characters in a couple of places.

ipv6: reduce per device ICMP mib sizes

2011-05-19T20:21:22Z

ipv6 has per device ICMP SNMP counters, taking too much space because they use percpu storage. needed size per device is : (512+4)*sizeof(long)*number_of_possible_cpus*2 On a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of memory per ipv6 enabled network device, taken in vmalloc pool. Since ICMP messages are rare, just use shared counters (atomic_long_t) Per network space ICMP counters are still using percpu memory, we might also convert them to shared counters in a future patch.

net: Remove KERNEL cpp checks from include/net

2011-04-24T17:54:56Z

These header files are never installed to user consumption, so any __KERNEL__ cpp checks are superfluous. Projects should also not copy these files into their userland utility sources and try to use them there. If they insist on doing so, the onus is on them to sanitize the headers as needed.

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

net: gre: provide multicast mappings for ipv4 and ipv6

2011-03-30T07:10:47Z

My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device. Reported-by: Doug Kehn Signed-off-by: Timo Teräs Acked-by: Doug Kehn Signed-off-by: David S.

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

ipv6: Replace inet6_ifaddr->dead with state

2010-05-18T22:36:06Z

This patch replaces the boolean dead flag on inet6_ifaddr with a state enum. This allows us to roll back changes when deleting an address according to whether DAD has completed or not. This patch only adds the state field and does not change the logic. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

ipv6: convert idev_list to list macros

IPv6: convert addrconf hash list to RCU

2010-03-20T22:44:35Z

Convert from reader/writer lock to RCU and spinlock for addrconf hash list. Adds an additional helper macro for hlist_for_each_entry_continue_rcu to handle the continue case. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

ipv6: convert addrconf list to hlist

2010-03-20T22:44:34Z

Using hash list macros, simplifies code and helps later RCU. This patch includes some initialization that is not strictly necessary, since an empty hlist node/list is all zero; and list is in BSS and node is allocated with kzalloc. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller
