[ Upstream commit f0ecde1466f21edf577b809735f4f35f354777a0 ] Need to check both CONFIG_FOO and CONFIG_FOO_MODULE Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

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.

ipv4: ARP neigh procfs buffer overflow

If arp_format_neigh_entry() can be called with n->dev->addr_len == 0, then a write to hbuffer[-1] occurs. Signed-off-by: Roel Kluin Signed-off-by: David S. Miller

Revert "ipv4: arp announce, arp_proxy and windows ip conflict verification"

2009-07-01T02:47:08Z

This reverts commit 73ce7b01b4496a5fbf9caf63033c874be692333f. After discovering that we don't listen to gratuitious arps in 2.6.30 I tracked the failure down to this commit. The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227. are all in agreement that an arp request with sip == 0 should be used for the probe (to prevent learning) and an arp request with sip == tip should be used for the gratitous announcement that people can learn from. It appears the author of the broken patch got those two cases confused and modified the code to drop all gratuitous arp traffic. Ouch! Cc: stable@kernel.org Signed-off-by: Eric W.

net: skb->dst accessors

2009-06-03T09:51:04Z

Define three accessors to get/set dst attached to a skb struct dst_entry *skb_dst(const struct sk_buff *skb) void skb_dst_set(struct sk_buff *skb, struct dst_entry *dst) void skb_dst_drop(struct sk_buff *skb) This one should replace occurrences of : dst_release(skb->dst) skb->dst = NULL; Delete skb->dst field Signed-off-by: Eric Dumazet Signed-off-by: David S.

net: skb->rtable accessor

2009-06-03T09:51:02Z

Define skb_rtable(const struct sk_buff *skb) accessor to get rtable from skb Delete skb->rtable field Setting rtable is not allowed, just set dst instead as rtable is an alias. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipv4: arp announce, arp_proxy and windows ip conflict verification

2009-03-13T23:02:07Z

Windows (XP at least) hosts on boot, with configured static ip, performing address conflict detection, which is defined in RFC3927. Here is quote of important information: " An ARP announcement is identical to the ARP Probe described above, except that now the sender and target IP addresses are both set to the host's newly selected IPv4 address. " But it same time this goes wrong with RFC5227. " The 'sender IP address' field MUST be set to all zeroes; this is to avoid polluting ARP caches in other hosts on the same link in the case where the address turns out to be already in use by another host. " When ARP proxy configured, it must not answer to both cases, because it is address conflict verification in any case. For Windows it is just causing to detect false "ip conflict". Already there is code for RFC5227, so just trivially we just check also if source ip == target ip. Signed-off-by: Denys Fedoryshchenko Signed-off-by: David S. Miller
