[PATCH] Netfilter ip_queue: Fix wrong skb->len == nlmsg_len assumption

2006-03-28T07:00:21+00:00

The size of the skb carrying the netlink message is not equivalent to the length of the actual netlink message due to padding. ip_queue matches the length of the payload against the original packet size to determine if packet mangling is desired, due to the above wrong assumption arbitary packets may not be mangled depening on their original size.

[PATCH] Address autoconfiguration does not work after device down/up cycle

2006-03-01T22:36:34+00:00

If you set network interface down and up again, the IPv6 address autoconfiguration does not work. 'ip addr' shows that the link-local address is in tentative state. We don't even react to periodical router advertisements. During NETDEV_DOWN we clear IF_READY, and we don't set it back in NETDEV_UP. While starting to perform DAD on the link-local address, we notice that the device is not in IF_READY, and we abort autoconfiguration process (which would eventually send router solicitations).

[IPV6] mcast: Fix multiple issues in MLDv2 reports.

2005-12-27T22:03:00+00:00

The below "jumbo" patch fixes the following problems in MLDv2. 1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks all nonzero source queries on little-endian (!)] 2) Add locking to source filter list [resend of prior patch] 3) fix "mld_marksources()" to a) send nothing when all queried sources are excluded b) send full exclude report when source queried sources are not excluded c) don't schedule a timer when there's nothing to report NOTE: RFC 3810 specifies the source list should be saved and each source reported individually as an IS_IN. This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!

[IPV6]: Fix addrconf dead lock.

2005-12-27T21:35:15+00:00

We need to release idev->lcok before we call addrconf_dad_stop(). It calls ipv6_addr_del(), which will hold idev->lock. Bug spotted by Yasuyuki KOZAKAI . Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

[IPV6]: Fix Temporary Address Generation

[IPV6]: Fix address deletion

2005-12-22T02:47:24+00:00

If you add more than one IPv6 address belonging to the same prefix and delete the address that was last added, routing table entry for that prefix is also deleted. Tested on 2.6.14.4 To reproduce: ip addr add 3ffe::1/64 dev eth0 ip addr add 3ffe::2/64 dev eth0 /* wait DAD */ sleep 1 ip addr del 3ffe::2/64 dev eth0 ip -6 route (route to 3ffe::/64 should be gone) In ipv6_del_addr(), if ifa == ifp, we set ifa->if_next to NULL, and later assign ifap = &ifa->if_next, effectively terminating the for-loop. This prevents us from checking if there are other addresses using the same prefix that are valid, and thus resulting in deletion of the prefix. This applies only if the first entry in idev->addr_list is the address to be deleted. Signed-off-by: Kristian Slavov Acked-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

[IPV6]: Don't select a tentative address as a source address.

2005-12-21T13:58:01+00:00

A tentative address is not considered "assigned to an interface" in the traditional sense (RFC2462 Section 4). Don't try to select such an address for the source address. Signed-off-by: YOSHIFUJI Hideaki
