'maps' is a generic storage of different types for sharing data between kernel
and userspace.
The maps are accessed from user space via BPF syscall, which has commands:
- create a map with given type and attributes
fd = bpf(BPF_MAP_CREATE, union bpf_attr *attr, u32 size)
returns fd or negative error
- lookup key in a given map referenced by fd
err = bpf(BPF_MAP_LOOKUP_ELEM, union bpf_attr *attr, u32 size)
using attr->map_fd, attr->key, attr->value
returns zero and stores found elem into value or negative error
- create or update key/value pair in a given map
err = bpf(BPF_MAP_UPDATE_ELEM, union bpf_attr *attr, u32 size)
using attr->map_fd, attr->key, attr->value
returns zero or negative error
- find and delete element by key in a given map
err = bpf(BPF_MAP_DELETE_ELEM, union bpf_attr *attr, u32 size)
using attr->map_fd, attr->key
- iterate map elements (based on input key return next_key)
err = bpf(BPF_MAP_GET_NEXT_KEY, union bpf_attr *attr, u32 size)
using attr->map_fd, attr->key, attr->next_key
- close(fd) deletes the map

BPF syscall is a multiplexor for a range of different operations on eBPF.
This patch introduces syscall with single command to create a map.
Next patch adds commands to access maps.
'maps' is a generic storage of different types for sharing data between kernel
and userspace.
Userspace example:
/* this syscall wrapper creates a map with given type and attributes
* and returns map_fd on success.
* use close(map_fd) to delete the map
*/
int bpf_create_map(enum bpf_map_type map_type, int key_size,
int value_size, int max_entries)
{
union bpf_attr attr = {
.map_type = map_type,
.key_size = key_size,
.value_size = value_size,
.max_entries = max_entries
};
return bpf(BPF_MAP_CREATE, &attr, sizeof(attr));
}
'union bpf_attr' is backwards compatible with future extensions.

This patch changes IP tunnel to support (secondary) encapsulation,
Foo-over-UDP. Changes include:
1) Adding tun_hlen as the tunnel header length, encap_hlen as the
encapsulation header length, and hlen becomes the grand total
of these.
2) Added common netlink define to support FOU encapsulation.
3) Routines to perform FOU encapsulation.

This patch provides a receive path for foo-over-udp. This allows
direct encapsulation of IP protocols over UDP. The bound destination
port is used to map to an IP protocol, and the XFRM framework
(udp_encap_rcv) is used to receive encapsulated packets. Upon
reception, the encapsulation header is logically removed (pointer
to transport header is advanced) and the packet is reinjected into
the receive path with the IP protocol indicated by the mapping.
Netlink is used to configure FOU ports. The configuration information
includes the port number to bind to and the IP protocol corresponding
to that port.
This should support GRE/UDP
(http://tools.ietf.org/html/draft-yong-tsvwg-gre-in-udp-encap-02),
as will as the other IP tunneling protocols (IPIP, SIT).

This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.

This patch exposes the ruleset generation ID in three ways:
1) The new command NFT_MSG_GETGEN that exposes the 32-bits ruleset
generation ID. This ID is incremented in every commit and it
should be large enough to avoid wraparound problems.
2) The less significant 16-bits of the generation ID are exposed through
the nfgenmsg->res_id header field. This allows us to quickly catch
if the ruleset has change between two consecutive list dumps from
different object lists (in this specific case I think the risk of
wraparound is unlikely).
3) Userspace subscribers may receive notifications of new rule-set
generation after every commit. This also provides an alternative
way to monitor the generation ID. If the events are lost, the
userspace process hits a overrun error, so it knows that it is
working with a stale ruleset anyway.
Patrick spotted that rule-set transformations in userspace may take
quite some time. In that case, it annotates the 32-bits generation ID
before fetching the rule-set, then:
1) it compares it to what we obtain after the transformation to
make sure it is not working with a stale rule-set and no wraparound
has ocurred.
2) it subscribes to ruleset notifications, so it can watch for new
generation ID.
This is complementary to the NLM_F_DUMP_INTR approach, which allows
us to detect an interference in the middle one single list dumping.
There is no way to explicitly check that an interference has occurred
between two list dumps from the kernel, since it doesn't know how
many lists the userspace client is actually going to dump.

====================
This pull requests makes the following changes:
* Add simple weighted fail-over scheduler.
- Unlike other IPVS schedulers this offers fail-over rather than load
balancing. Connections are directed to the appropriate server based
solely on highest weight value and server availability.
- Thanks to Kenny Mathis
* Support IPv6 real servers in IPv4 virtual-services and vice versa
- This feature is supported in conjunction with the tunnel (IPIP)
forwarding mechanism. That is, IPv4 may be forwarded in IPv6 and
vice versa.
- The motivation for this is to allow more flexibility in the
choice of IP version offered by both virtual-servers and
real-servers as they no longer need to match: An IPv4 connection from an
end-user may be forwarded to a real-server using IPv6 and vice versa.
- Further work need to be done to support this feature in conjunction
with connection synchronisation. For now such configurations are
not allowed.
- This change includes update to netlink protocol, adding a new
destination address family attribute. And the necessary changes
to plumb this information throughout IPVS.
- Thanks to Alex Gartrell and Julian Anastasov

This patch introduces virtual endpoint address mapping. It separates
function logic form physical endpoint addresses making it more hardware
independent.
Following modifications changes user space API, so to enable them user
have to switch on the FUNCTIONFS_VIRTUAL_ADDR flag in descriptors.
Endpoints are now refered using virtual endpoint addresses chosen by
user in endpoint descpriptors. This applies to each context when endpoint
address can be used:
- when accessing endpoint files in FunctionFS filesystemi (in file name),
- in setup requests directed to specific endpoint (in wIndex field),
- in descriptors returned by FUNCTIONFS_ENDPOINT_DESC ioctl.
In endpoint file names the endpoint address number is formatted as
double-digit hexadecimal value ("ep%02x") which has few advantages -
it is easy to parse, allows to easly recognize endpoint direction basing
on its name (IN endpoint number starts with digit 8, and OUT with 0)
which can be useful for debugging purpose, and it makes easier to introduce
further features allowing to use each endpoint number in both directions
to have more endpoints available for function if hardware supports this
(for example we could have ep01 which is endpoint 1 with OUT direction,
and ep81 which is endpoint 1 with IN direction).
Physical endpoint address can be still obtained using ioctl named
FUNCTIONFS_ENDPOINT_REVMAP, but now it's not neccesary to handle
USB transactions properly.

Recirc action allows a packet to reenter openvswitch processing.
currently openvswitch lookup flow for packet received and execute
set of actions on that packet, with help of recirc action we can
process/modify the packet and recirculate it back in openvswitch
for another pass.
OVS hash action calculates 5-tupple hash and set hash in flow-key
hash. This can be used along with recirculation for distributing
packets among different ports for bond devices.
For example:
OVS bonding can use following actions:
Match on: bond flow; Action: hash, recirc(id)
Match on: recirc-id == id and hash lower bits == a;
Action: output port_bond_a

This is necessary to support heterogeneous pools. For example, if you have
an ipv6 addressed network, you'll want to be able to forward ipv4 traffic
into it.
This patch enforces that destination address family is the same as service
family, as none of the forwarding mechanisms support anything else.
For the old setsockopt mechanism, we simply set the dest address family to
AF_INET as we do with the service.
