Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert.

| * xfrm: Namespacify xfrm state/policy locksFan Du2013-12-061-49/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By semantics, xfrm layer is fully name space aware, so will the locks, e.g. xfrm_state/pocliy_lock. Ensure exclusive access into state/policy link list for different name space with one global lock is not right in terms of semantics aspect at first place, as they are indeed mutually independent with each other, but also more seriously causes scalability problem. One practical scenario is on a Open Network Stack, more than hundreds of lxc tenants acts as routers within one host, a global xfrm_state/policy_lock becomes the bottleneck. But onces those locks are decoupled in a per-namespace fashion, locks contend is just with in specific name space scope, without causing additional SPD/SAD access delay for other name space. Also this patch improve scalability while as without changing original xfrm behavior. Signed-off-by: Fan Du <fan.du@windriver.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

| * xfrm: Fix potential null pointer dereference in xdst_queue_outputSteffen Klassert2013-08-281-8/+1
| | | | | | | | | | | | | | | | | | | | | | The net_device might be not set on the skb when we try refcounting. This leads to a null pointer dereference in xdst_queue_output(). It turned out that the refcount to the net_device is not needed after all. The dst_entry has a refcount to the net_device before we queue the skb, so it can't go away. Therefore we can remove the refcount on queueing to fix the null pointer dereference. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

That commit removed returning -EREMOTE in the xfrm_lookup() method when the packet should be discarded and also removed the correspoinding -EREMOTE handlers.

| * xfrm: force a garbage collection after deleting a policyPaul Moore2013-05-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | In some cases after deleting a policy from the SPD the policy would remain in the dst/flow/route cache for an extended period of time which caused problems for SELinux as its dynamic network access controls key off of the number of XFRM policy and state entries. This patch corrects this problem by forcing a XFRM garbage collection whenever a policy is sucessfully removed.

| | | | | | | | | | | | | | | | | | because xfrm policy direction has same value with corresponding flow direction, so this problem is covered. In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to accelerate the lookup. Flow direction is given to flow_cache_lookup by policy_to_flow_dir. When the flow cache is mismatched, callback 'resolver' is called. 'resolver' requires xfrm direction, so convert direction back to xfrm direction.

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

| * xfrm: Add a state resolution packet queueSteffen Klassert2013-02-061-4/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the default, we blackhole packets until the key manager resolves the states. This patch implements a packet queue where IPsec packets are queued until the states are resolved. We generate a dummy xfrm bundle, the output routine of the returned route enqueues the packet to a per policy queue and arms a timer that checks for state resolution when dst_output() is called. Once the states are resolved, the packets are sent out of the queue. If the states are not resolved after some time, the queue is flushed. This patch keeps the defaut behaviour to blackhole packets as long as we have no states. To enable the packet queue the sysctl xfrm_larval_drop must be switched off.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation.

This allows the code to code to compile with user namespaces enabled and removes the assumption there is only the initial user namespace. Everything is converted except for the most complex of the filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs, nfs, ocfs2 and xfs as those patches need a bit more review. The strategy is to push kuid_t and kgid_t values are far down into subsystems and filesystems as reasonable. Leaving the make_kuid and from_kuid operations to happen at the edge of userspace, as the values come off the disk, and as the values come in from the network. Letting compile type incompatible compile errors (present when user namespaces are enabled) guide me to find the issues. The most tricky areas have been the places where we had an implicit union of uid and gid values and were storing them in an unsigned int. Those places were converted into explicit unions. I made certain to handle those places with simple trivial patches. Out of that work I discovered we have generic interfaces for storing quota by projid. I had never heard of the project identifiers before. Adding full user namespace support for project identifiers accounts for most of the code size growth in my git tree. Ultimately there will be work to relax privlige checks from "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing root in a user names to do those things that today we only forbid to non-root users because it will confuse suid root applications. While I was pushing kuid_t and kgid_t changes deep into the audit code I made a few other cleanups. I capitalized on the fact we process netlink messages in the context of the message sender. I removed usage of NETLINK_CRED, and started directly using current->tty. Some of these patches have also made it into maintainer trees, with no problems from identical code from different trees showing up in linux-next. After reading through all of this code I feel like I might be able to win a game of kernel trivial pursuit."

| | | | | | | | | | | | | | | | | | | | | | | Since commit ad0081e43a "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed" the fragment of packets is incorrect. because tunnel mode needs IPsec headers and trailer for all fragments, while on transport mode it is sufficient to add the headers to the first fragment and the trailer to the last. so modify mtu and maxfraglen base on ipsec mode and if fragment is first or last. with my test,it work well(every fragment's size is the mtu) and does not trigger slow fragment path. Changes from v1: though optimization, mtu_prev and maxfraglen_prev can be delete. replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL. add fuction ip6_append_data_mtu to make codes clearer.
