Since there is no connection between the MAC/VLAN and the GID
when using IP-based addressing, the proxy QP1 (running on the
slave) must pass the source-mac, destination-mac, and vlan_id
information separately from the GID. Additionally, the Host
must pass the remote source-mac and vlan_id back to the slave,
This is achieved as follows:
Outgoing MADs:
1. Source MAC: obtained from the CQ completion structure
(struct ib_wc, smac field).
2. Destination MAC: obtained from the tunnel header
3. vlan_id: obtained from the tunnel header.
Incoming MADs
1. The source (i.e., remote) MAC and vlan_id are passed in
the tunnel header to the proxy QP1.
VST mode support:
For outgoing MADs, the vlan_id obtained from the header is
discarded, and the vlan_id specified by the Hypervisor is used
instead.
For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the
"invalid" vlan (0xffff) is substituted when forwarding to the slave.

The GIDs are statically distributed, as follows:
PF: gets 16 GIDs
VFs: Remaining GIDS are divided evenly between VFs activated by the driver.
If the division is not even, lower-numbered VFs get an extra GID.
For an IB interface, the number of gids per guest remains as before: one gid per guest.

For IB transport, the host determines the slave GIDs. For ETH (RoCE),
however, the slave's GID is determined by the IP address that the slave
itself assigns to the ETH device used by RoCE.
In this case, the slave must be able to write its GIDs to the HCA gid table
(at the GID indices that slave "owns").
This commit adds processing for the SET_PORT_GID_TABLE opcode modifier
for the SET_PORT command wrapper (so that slaves may modify their GIDS
for RoCE).

This requires the following modifications:
1. Fix build_mlx4_header to properly fill in the ETH fields
2. Adjust mux and demux QP1 flow to support RoCE.
This commit still assumes only one GID per slave for RoCE.
The commit enabling multiple GIDs is a subsequent commit, and
is done separately because of its complexity.

We leak an active timer, the hotcpu notifier and all allocated
resources when we exit a namespace. Fix this by introducing a
flow_cache_fini() function where we release the resources before
we exit.

This patch fixes sparse warnings in vlan driver.
It propagates the sparse __percpu attribute from alloc_percpu
into netdev_alloc_pcpu_stats. I expect it may trigger additional

====================
pull-request: can-next 2014-02-12
this is a pull request of twelve patches for net-next/master.
Alexander Shiyan contributes two patches for the mcp251x, one making
the driver more quiet and the other one improves the compile time
coverage by removing the #ifdef CONFIG_PM_SLEEP. Then two patches for
the flexcan driver by me, one removing the #ifdef CONFIG_PM_SLEEP, too,
the other one making use of platform_get_device_id(). Another patch by
me which converts the janz-ican3 driver to use netdev_<level>(). The
remaining 7 patches are by Oliver Hartkopp, they add CAN FD support to
the netlink configuration interface.

The configuration for CAN FD depends on CAN_CTRLMODE_FD enabled in the driver
specific ctrlmode_supported capabilities.
The configuration can be done either with the 'fd { on | off }' option in the
'ip' tool from iproute2 or by setting the CAN netdevice MTU to CAN_MTU (16) or
to CANFD_MTU (72).

Commit e688a604807647 ("net: introduce DST_NOPEER dst flag") introduced
DST_NOPEER because because of crashes in ipv6_select_ident called from
udp6_ufo_fragment.
Since commit 916e4cf46d0204 ("ipv6: reuse ip6_frag_id from
ip6_ufo_append_data") we don't call ipv6_select_ident any more from
ip6_ufo_append_data, thus this flag lost its purpose and can be removed.

When doing some numa tests on powerpc, I triggered an oops bug. I find
it is caused by using page->_last_cpupid. It should be initialized as
"-1 & LAST_CPUPID_MASK", but not "-1". Otherwise, in task_numa_fault(),
we will miss the checking (last_cpupid == (-1 & LAST_CPUPID_MASK)). And
finally cause an oops bug in task_numa_group(), since the online cpu is
less than possible cpu. This happen with CONFIG_SPARSE_VMEMMAP disabled

because munlock_vma_pages_range() thinks it's unexpectedly in the middle
of a THP page. This can be reproduced with default config since 3.11
kernels. A reproducer can be found in the kernel's selftest directory
for networking by running ./psock_tpacket.
The problem is that an order=2 compound page (allocated by
alloc_one_pg_vec_page() is part of the munlocked VM_MIXEDMAP vma (mapped
by packet_mmap()) and mistaken for a THP page and assumed to be order=9.
The checks for THP in munlock came with commit ff6a6da60b89 ("mm:
accelerate munlock() treatment of THP pages"), i.e. since 3.9, but did
not trigger a bug. It just makes munlock_vma_pages_range() skip such
compound pages until the next 512-pages-aligned page, when it encounters
a head page. This is however not a problem for vma's where mlocking has
no effect anyway, but it can distort the accounting.
Since commit 7225522bb429 ("mm: munlock: batch non-THP page isolation
and munlock+putback using pagevec") this can trigger a VM_BUG_ON in
PageTransHuge() check.
This patch fixes the issue by adding VM_MIXEDMAP flag to VM_SPECIAL, a
list of flags that make vma's non-mlockable and non-mergeable. The
reasoning is that VM_MIXEDMAP vma's are similar to VM_PFNMAP, which is
already on the VM_SPECIAL list, and both are intended for non-LRU pages
where mlocking makes no sense anyway. Related Lkml discussion can be
found in [2].

Commit bf6bddf1924e ("mm: introduce compaction and migration for
ballooned pages") introduces page_count(page) into memory compaction
which dereferences page->first_page if PageTail(page).
This results in a very rare NULL pointer dereference on the
aforementioned page_count(page). Indeed, anything that does
compound_head(), including page_count() is susceptible to racing with
prep_compound_page() and seeing a NULL or dangling page->first_page
pointer.
This patch uses Andrea's implementation of compound_trans_head() that
deals with such a race and makes it the default compound_head()
implementation. This includes a read memory barrier that ensures that
if PageTail(head) is true that we return a head page that is neither
NULL nor dangling. The patch then adds a store memory barrier to
prep_compound_page() to ensure page->first_page is set.
This is the safest way to ensure we see the head page that we are
expecting, PageTail(page) is already in the unlikely() path and the
memory barriers are unfortunately required.
Hugetlbfs is the exception, we don't enforce a store memory barrier
during init since no race is possible.

Add the following snmp stats:
TCPFastOpenActiveFail: Fast Open attempts (SYN/data) failed beacuse
the remote does not accept it or the attempts timed out.
TCPSynRetrans: number of SYN and SYN/ACK retransmits to break down
retransmissions into SYN, fast-retransmits, timeout retransmits, etc.
TCPOrigDataSent: number of outgoing packets with original data (excluding
retransmission but including data-in-SYN). This counter is different from
TcpOutSegs because TcpOutSegs also tracks pure ACKs. TCPOrigDataSent is
more useful to track the TCP retransmission rate.
Change TCPFastOpenActive to track only successful Fast Opens to be symmetric to

There is a single framework fix that prevents dereferencing a NULL

cause things to explode, misconfigured clock rates that result in
non-responsive devices and even some boot failures. The most benign
fix is DT binding doc typo. It is a stable ABI exposed from the

This patch drops the current way of 6lowpan fragmentation on receiving
side and replace it with a implementation which use the inet_frag api.
The old fragmentation handling has some race conditions and isn't
rfc4944 compatible. Also adding support to match fragments on
destination address, source address, tag value and datagram_size
which is missing in the current implementation.

Pull sound fixes from Takashi Iwai:
"It's a bad habit to get a higher volume of fixes often lately, but
things happen again.
All commits found here are real bug fixes, and are mostly trivial.
Most of changes in ASoC are the fixes for enum items due to the wrong
API usages, in addition to a few DAPM mutex deadlock and other fixes.
In HD-audio, only fixups for HP laptops. Although diffstat shows
much, the changes are simple: there are just so many different device
entries there"

There should be no users of the two functions now. So remove them.

The stop_scan_complete function was used as an intermediate step before
doing the actual connection creation. Since we're using hci_request
there's no reason to have this extra function around, i.e. we can simply
put both HCI commands into the same request.
The single task that the intermediate function had, i.e. indicating
discovery as stopped is now taken care of by a new
HCI_LE_SCAN_INTERRUPTED flag which allows us to do the discovery state
update when the stop scan command completes.

LE connection attempts do not have a controller side timeout in the same
way as BR/EDR has (in form of the page timeout). Since we always do
scanning before initiating connections the attempts are always expected
to succeed in some reasonable time.
This patch adds a timer which forces a cancellation of the connection
attempt within 20 seconds if it has not been successful by then. This
way we e.g. ensure that mgmt_pair_device times out eventually and gives
an error response.

For SMP we need the local and remote addresses (and their types) that
were used to establish the connection. These may be different from the
Identity Addresses or even the current RPA. To guarantee that we have
this information available and it is correct track these values
separately from the very beginning of the connection.
For outgoing connections we set the values as soon as we get a
successful command status for HCI_LE_Create_Connection (for which the
patch adds a command status handler function) and for incoming
connections as soon as we get a LE Connection Complete HCI event.

If some of the cleanup commands caused by mgmt_set_powered(off) never
complete we should still force the adapter to be powered down. This is
rather easy to do since hdev->power_off is already a delayed work
struct. This patch schedules this delayed work if at least one HCI
command was sent by the cleanup procedure.

====================
This is the rework of the IPsec virtual tunnel interface
for ipv4 to support inter address family tunneling and
namespace crossing. The only change to the last RFC version
is a compile fix for an odd configuration where CONFIG_XFRM
is set but CONFIG_INET is not set.
1) Add and use a IPsec protocol multiplexer.
2) Add xfrm_tunnel_skb_cb to the skb common buffer
to store a receive callback there.
3) Make vti work with i_key set by not including the i_key
when comupting the hash for the tunnel lookup in case of
vti tunnels.
4) Update ip_vti to use it's own receive hook.
5) Remove xfrm_tunnel_notifier, this is replaced by the IPsec
protocol multiplexer.
6) We need to be protocol family indepenent, so use the on xfrm_lookup
returned dst_entry instead of the ipv4 rtable in vti_tunnel_xmit().
7) Add support for inter address family tunneling.
8) Check if the tunnel endpoints of the xfrm state and the vti interface
are matching and return an error otherwise.
8) Enable namespace crossing tor vti devices.

1) Build fix for ip_vti when NET_IP_TUNNEL is not set.
We need this set to have ip_tunnel_get_stats64()
available.
2) Fix a NULL pointer dereference on sub policy usage.
We try to access a xfrm_state from the wrong array.
3) Take xfrm_state_lock in xfrm_migrate_state_find(),
we need it to traverse through the state lists.
4) Clone states properly on migration, otherwise we crash
when we migrate a state with aead algorithm attached.
5) Fix unlink race when between thread context and timer
when policies are deleted.

We have documentation for these flags but they're scattered
all over the place. #defines don't allow documentation to be
written easily so to help to start bringing some documentation
together use the enums kdoc practice but keep the defines to
allow userspace to be able to #ifdef them.
I've verified the same values are assigned before and after
with a simple userspace test program [0] and checksumming the
output.
