ipv6: Remove never used function inet6_ac_check().

2012-02-01T21:14:17Z

It went from unused, to commented out, and never changing after that. Just get rid of it, if someone wants it they can unearth it from the history. Signed-off-by: David S. Miller

ipv6: Check RA for sllao when configuring optimistic ipv6 address (v2)

2012-01-04T20:53:20Z

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop route for the interface we're adding an addres to was wrong (see commit 7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069). for one, it never triggers, and two, it was completely wrong to begin with. This test was meant to cover this section of RFC 4429: 3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration * (modifies section 5.5) A host MAY choose to configure a new address as an Optimistic Address. A host that does not know the SLLAO of its router SHOULD NOT configure a new address as Optimistic. A router SHOULD NOT configure an Optimistic Address. This patch should bring us into proper compliance with the above clause. Since we only add a SLAAC address after we've received a RA which may or may not contain a source link layer address option, we can pass a pointer to that option to addrconf_prefix_rcv (which may be null if the option is not present), and only set the optimistic flag if the option was found in the RA. Change notes: (v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than a pointer to make its use more clear as per request from davem. Signed-off-by: Neil Horman CC: "David S.

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.

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: kill unused macros from head file

2010-12-02T21:27:33Z

These macros have been defined for several years since v2.6.12-rc2（tracing by git）, but never be used. So remove them. Signed-off-by: Shan Wei Signed-off-by: David S. Miller

ipv6: add a missing unregister_pernet_subsys call

2010-09-27T02:09:25Z

Clean up a missing exit path in the ipv6 module init routines. In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.
