| | | | | | | | | | | | | | | | | | | | | | | | Those reduced to DEBUG can possibly be triggered by unprivileged processes and are nothing exceptional. Illegal checksum combinations can only be caused by driver bug, so promote those messages to WARN. Since GSO without SG will now only cause DEBUG message from netdev_fix_features(), remove the workaround from register_netdevice().

| | | | | | | | | | | | | | | | | | | | Without this patch every access to ip_vs in procfs will increase the netns count i.e. an unbalanced get_net()/put_net(). (ipvsadm commands also use procfs.) The result is you can't exit a netns if reading ip_vs_* procfs entries. Signed-off-by: Hans Schillstrom <hans.schillstrom@ericsson.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are disconnecting, we set PS off, but this happens before we send the deauth/disassoc request. When the deauth/disassoc frames are sent, we trigger the dynamic ps timer, which then times out and turns PS back on. Thus, PS remains on after disconnecting, causing problems when associating again. This can be fixed by preventing the timer to start when we're not associated anymore. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Netns also requires action when net devices unregister which has never been implemented. I.e this patch also covers when a device moves into a network namespace, and has to be released. IMPLEMENTATION The number of calls to register_pernet_device have been reduced to one for the ip_vs.ko Schedulers still have their own calls. This patch adds a function __ip_vs_service_cleanup() and an enable flag for the netfilter hooks. The nf hooks will be enabled when the first service is loaded and never disabled again, except when a namespace exit starts.

When all patches are there, ip_vs_core will handle register_pernet_(), i.e. ip_vs_sync_init() and ip_vs_sync_cleanup() will be removed. Kernel threads should not increment the use count of a socket. By calling sk_change_net() after creating a socket this is avoided. sock_release cant be used intead sk_release_kernel() should be used. Thanks Eric W Biederman for your advices.

RFC 4303 states: Note: If a receiver chooses to not enable anti-replay for an SA, then the receiver SHOULD NOT negotiate ESN in an SA management protocol. Use of ESN creates a need for the receiver to manage the anti-replay window (in order to determine the correct value for the high-order bits of the ESN, which are employed in the ICV computation), which is generally contrary to the notion of disabling anti-replay for an SA. So return an error if an ESN state with disabled anti replay detection is inserted for now and add the extra treatment later if we need it.

| * | | xfrm: Assign the inner mode output function to the dst entrySteffen Klassert2011-05-10

This leads to two problems on interfamily scenarios. We might insert ipv4 packets into ip6_fragment when called from xfrm6_output. The system crashes if we try to fragment an ipv4 packet with ip6_fragment. This issue was introduced with git commit ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed). The second issue is, that we might insert ipv4 packets in netfilter6 and vice versa on interfamily scenarios. With this patch we assign the inner mode output function to the dst entry when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner mode is used and the right fragmentation and netfilter functions are called. We switch then to outer mode with the output_finish functions.

If an abnormally large number of packets are acknowledged at once, then the update could wrap and reach zero. This kind of ACK could only happen when there was a large window and huge number of ACK's were lost. This patch limits the value of delayed ack ratio. The choice of 32 is just a conservative value since normally it should be range of 1 to 4 packets. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path) added a bug in IP defragmentation handling, in case timeout is fired. When a frame is defragmented, we use last skb dst field when building final skb. Its dst is valid, since we are in rcu read section. But if a timeout occurs, we take first queued fragment to build one ICMP TIME EXCEEDED message. Problem is all queued skb have weak dst pointers, since we escaped RCU critical section after their queueing. icmp_send() might dereference a now freed (and possibly reused) part of memory. Calling skb_dst_drop() and ip_route_input_noref() to revalidate route is the only possible choice.
