ipv6: fix NULL reference in proxy neighbor discovery

2010-08-02T17:26:35Z

commit 9f888160bdcccf0565dd2774956b8d9456e610be upstream. The addition of TLLAO option created a kernel OOPS regression for the case where neighbor advertisement is being sent via proxy path. When using proxy, ipv6_get_ifaddr() returns NULL causing the NULL dereference. Change causing the bug was: commit f7734fdf61ec6bb848e0bafc1fb8bad2c124bb50 Author: Octavian Purdila Date: Fri Oct 2 11:39:15 2009 +0000 make TLLAO option for NA packets configurable Signed-off-by: Stephen Hemminger Acked-by: YOSHIFUJI Hideaki Signed-off-by: David S.

sysctl net: Remove unused binary sysctl code

2009-11-12T10:05:06Z

Now that sys_sysctl is a compatiblity wrapper around /proc/sys all sysctl strategy routines, and all ctl_name and strategy entries in the sysctl tables are unused, and can be revmoed. In addition neigh_sysctl_register has been modified to no longer take a strategy argument and it's callers have been modified not to pass one.

This patch adds a new sysctl option (disabled by default) which controls whether this option should be sent even with unicast NAs. The need for this arose because certain routers expect the TLLAO in some situations even as a response to unicast NS packets. Moreover, RFC 2461 recommends sending this to avoid a race condition (section 4.4, Target link-layer address) Signed-off-by: Cosmin Ratiu Signed-off-by: Octavian Purdila Signed-off-by: David S.

Revert "sit: stateless autoconf for isatap"

2009-09-27T03:28:07Z

This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by: Sascha Hlusiak Acked-by: Fred L. Templin Signed-off-by: David S. Miller

sysctl: remove "struct file *" argument of ->proc_handler

2009-09-24T14:21:04Z

It's unused. It isn't needed -- read or write flag is already passed and sysctl shouldn't care about the rest. It _was_ used in two places at arch/frv for some reason.

ipv6: Update Neighbor Cache when IPv6 RA is received on a router

2009-08-29T07:04:09Z

When processing a received IPv6 Router Advertisement, the kernel creates or updates an IPv6 Neighbor Cache entry for the sender -- but presently this does not occur if IPv6 forwarding is enabled (net.ipv6.conf.*.forwarding = 1), or if IPv6 Router Advertisements are not accepted (net.ipv6.conf.*.accept_ra = 0), because in these cases processing of the Router Advertisement has already halted. This patch allows the Neighbor Cache to be updated in these cases, while still avoiding any modification to routes or link parameters. This continues to satisfy RFC 4861, since any entry created in the Neighbor Cache as the result of a received Router Advertisement is still placed in the STALE state.
