Revert "ipv6: ndisc: inherit metadata dst when creating ndisc requests"

2015-12-15T05:40:56Z

[ Upstream commit 304d888b29cf96f1dd53511ee686499cd8cdf249 ] This reverts commit ab450605b35caa768ca33e86db9403229bf42be4. In IPv6, we cannot inherit the dst of the original dst. ndisc packets are IPv6 packets and may take another route than the original packet. This patch breaks the following scenario: a packet comes from eth0 and is forwarded through vxlan1. The encapsulated packet triggers an NS which cannot be sent because of the wrong route.

ipv6: ndisc: inherit metadata dst when creating ndisc requests

2015-08-20T22:42:37Z

If output device wants to see the dst, inherit the dst of the original skb in the ndisc request. This is an IPv6 counterpart of commit 0accfc268f4d ("arp: Inherit metadata dst when creating ARP requests"). Signed-off-by: Jiri Benc Acked-by: Thomas Graf Signed-off-by: David S. Miller

neigh: Factor out ___neigh_lookup_noref

2015-03-04T05:23:23Z

While looking at the mpls code I found myself writing yet another version of neigh_lookup_noref. We currently have __ipv4_lookup_noref and __ipv6_lookup_noref. So to make my work a little easier and to make it a smidge easier to verify/maintain the mpls code in the future I stopped and wrote ___neigh_lookup_noref. Then I rewote __ipv4_lookup_noref and __ipv6_lookup_noref in terms of this new function. I tested my new version by verifying that the same code is generated in ip_finish_output2 and ip6_finish_output2 where these functions are inlined. To get to ___neigh_lookup_noref I added a new neighbour cache table function key_eq. So that the static size of the key would be available. I also added __neigh_lookup_noref for people who want to to lookup a neighbour table entry quickly but don't know which neibhgour table they are going to look up. Signed-off-by: "Eric W.

ndisc.h: Remove extern from function prototypes

2013-09-21T18:01:39Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

ipv6: don't call fib6_run_gc() until routing is ready

2013-09-11T21:04:09Z

When loading the ipv6 module, ndisc_init() is called before ip6_route_init(). As the former registers a handler calling fib6_run_gc(), this opens a window to run the garbage collector before necessary data structures are initialized. If a network device is initialized in this window, adding MAC address to it triggers a NETDEV_CHANGEADDR event, leading to a crash in fib6_clean_all(). Take the event handler registration out of ndisc_init() into a separate function ndisc_late_init() and move it after ip6_route_init(). Signed-off-by: Michal Kubecek Signed-off-by: David S. Miller

ndisc: Convert use of typedef ctl_table to struct ctl_table

2013-06-20T06:18:07Z

This typedef is unnecessary and should just be removed. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

ndisc: Move ndisc_opt_addr_space() to include/net/ndisc.h.

2013-01-21T18:33:14Z

This also makes ndisc_opt_addr_data() and ndisc_fill_addr_option() use ndisc_opt_addr_space(). Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

ndisc: Introduce __ipv6_neigh_lookup_noref().

2013-01-17T23:38:18Z

This function, which looks up neighbour entry for an IPv6 address without touching refcnt, will be used for patches to remove dependency on rt->n (neighbour entry in rt6_info). Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller
