* [IPV6] mcast: Fix multiple issues in MLDv2 reports.David L Stevens2005-12-271-30/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!

* [BR_NETFILTER]: Fix leak if skb traverses > 1 bridgeDavid Kimdon2005-12-261-0/+2
| | | | | | | | | | Call nf_bridge_put() before allocating a new nf_bridge structure and potentially overwriting the pointer to a previously allocated one. This fixes a memory leak which can occur when the bridge topology allows for an skb to traverse more than one bridge.

* | [IPSEC]: Fix policy updates missed by socketsDavid S. Miller2005-12-221-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that when new policies are inserted, sockets do not see the update (but all new route lookups do). This bug is related to the SA insertion stale route issue solved recently, and this policy visibility problem can be fixed in a similar way. The fix is to flush out the bundles of all policies deeper than the policy being inserted. Consider beginning state of "outgoing" direction policy list: policy A --> policy B --> policy C --> policy D First, realize that inserting a policy into a list only potentially changes IPSEC routes for that direction. Therefore we need not bother considering the policies for other directions. We need only consider the existing policies in the list we are doing the inserting. Consider new policy "B'", inserted after B. policy A --> policy B --> policy B' --> policy C --> policy D Two rules: 1) If policy A or policy B matched before the insertion, they appear before B' and thus would still match after inserting B' 2) Policy C and D, now "shadowed" and after policy B', potentially contain stale routes because policy B' might be selected instead of them. Therefore we only need flush routes assosciated with policies appearing after a newly inserted policy, if any. Signed-off-by: David S. Miller <davem@davemloft.net>

* | [IPV6]: Fix address deletionKristian Slavov2005-12-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The argument of rt6_route_add() for adding a route is not the expiration time in jiffies nor in clock_t, but the lifetime (or time left before expiration) in clock_t.
