There is currently a race condition in the btmrvl_remove_card() which
is causing hangs on suspend for OLPC. When the race occurs,
kthread_stop() never returns.
The problem is that btmrvl_service_main_thread() calls kthread_should_stop()
and then does a fair number of things before restarting the loop and
sleeping.
If the thread gets stopped after kthread_should_stop() is checked, but
before the sleep happens, the thread will go to sleep and won't necessarily
be woken up.
Move the kthread_should_stop() check into a race-free place.

Even though the HCI_Delete_Stored_Link_Key command is mandatory for 1.1
and later controllers some controllers do not seem to support it
properly as was witnessed by one Broadcom based controller:
< HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7
bdaddr 00:00:00:00:00:00 all 1
> HCI Event: Command Complete (0x0e) plen 4
Delete Stored Link Key (0x03|0x0012) ncmd 1
status 0x11 deleted 0
Error: Unsupported Feature or Parameter Value
Luckily this same controller also doesn't list the command in its
supported commands bit mask (counting from 0 bit 7 of octet 6):
< HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local Supported Commands (0x04|0x0002) ncmd 1
status 0x00
Commands: ffffffffffff1ffffffffffff30fffff3f
Therefore, it makes sense to move sending of HCI_Delete_Stored_Link_Key
to after receiving the supported commands response and to only send it
if its respective bit in the mask is set. The downside of this is that
we no longer send the HCI_Delete_Stored_Link_Key command for Bluetooth
1.1 controllers since HCI_Read_Local_Supported_Command was introduced in
version 1.2, but this is an acceptable penalty as the command in
question shouldn't affect critical behavior.

When building a driver that only has one of MVM or DVM, there's
no reason to build the device support and have the PCIe IDs for
all devices since they can't be used anyway, so avoid that.

Linux sends new unset data during disorder and recovery state if all
(suspected) lost packets have been retransmitted ( RFC5681, section
3.2 step 1 & 2, RFC3517 section 4, NexSeg() Rule 2). One requirement
is to keep the receive window about twice the estimated sender's
congestion window (tcp_rcv_space_adjust()), assuming the fast
retransmits repair the losses in the next round trip.
But currently it's not the case on the first round trip in either
normal or Fast Open connection, beucase the initial receive window
is identical to (expected) sender's initial congestion window. The
fix is to double it.

Some systems that don't need wake-on-lan may choose to power down the
chip on system standby. Upon resume, the power on causes the boot code
to startup and initialize the hardware. On one new platform, this is
causing the device to go into a bad state due to a race between the
driver and boot code, once every several hundred resumes. The same race
exists on open since we come up from a power on.
This patch adds a wait for boot code signature at the beginning of
tg3_init_hw() which is common to both cases. If there has not been a
power-off or the boot code has already completed, the signature will be
present and poll_fw() returns immediately. Also return immediately if
the device does not have firmware.

First the type of igmp_retrans (which is the actual counter of
igmp_resend parameter) is changed to u8 to be able to store values up
to 255 (as per documentation). There are two races that were hidden
there and which are easy to trigger after the previous fix, the first is
between bond_resend_igmp_join_requests and bond_change_active_slave
where igmp_retrans is set and can be altered by the periodic. The second
race condition is between multiple running instances of the periodic
(upon execution it can be scheduled again for immediate execution which
can cause the counter to go < 0 which in the unsigned case leads to
unnecessary igmp retransmissions).
Since in bond_change_active_slave bond->lock is held for reading and
curr_slave_lock for writing, we use curr_slave_lock for mutual
exclusion. We can't drop them as there're cases where RTNL is not held
when bond_change_active_slave is called. RCU is unlocked in
bond_resend_igmp_join_requests before getting curr_slave_lock since we
don't need it there and it's pointless to delay.
The decrement is moved inside the "if" block because if we decrement
unconditionally there's still a possibility for a race condition although
it is much more difficult to hit (many changes have to happen in
a very short period in order to trigger) which in the case of 3 parallel
running instances of this function and igmp_retrans == 1
(with check bond->igmp_retrans-- > 1) is:
f1 passes, doesn't re-schedule, but decrements - igmp_retrans = 0
f2 then passes, doesn't re-schedule, but decrements - igmp_retrans = 255
f3 does the unnecessary retransmissions.

- fix "rtnl locked" concurrent executions by using rtnl_lock instead of
rtnl_trylock. This fix enables batman-adv initialisation to do not fail just
because somewhere else in the system another code path is holding the rtnl
lock. It is easy to see the problem when batman-adv is trying to start
together with other networking components.
- fix the routing protocol forwarding policy by enhancing the duplicate control
packet detection. When the right circumstances trigger the issue, some nodes in
the network become totally unreachable, so breaking the mesh connectivity.
- fix the Bridge Loop Avoidance component by not running the originator address
change handling routine when the component is disabled. The routine was

Merge tag 'batman-adv-fix-for-davem' of git://git.open-mesh.org/linux-merge
Included change:
- fix "rtnl locked" concurrent executions by using rtnl_lock instead of
rtnl_trylock. This fix enables batman-adv initialisation to do not fail just
because somewhere else in the system another code path is holding the rtnl
lock. It is easy to see the problem when batman-adv is trying to start
together with other networking components.
- fix the routing protocol forwarding policy by enhancing the duplicate control
packet detection. When the right circumstances trigger the issue, some nodes in
the network become totally unreachable, so breaking the mesh connectivity.
- fix the Bridge Loop Avoidance component by not running the originator address
change handling routine when the component is disabled. The routine was
generating useless packets that were sent over the network.

When putting vif-s on the rx notify list, calling xenvif_put() must be
deferred until after the removal from the list and the issuing of the
notification, as both operations dereference the pointer.
Changing this got me to notice that the "irq" variable was effectively
unused (and was of too narrow type anyway).

net_device::dev_id should not be used merely to indicate a VI index,
as it affects the way the local part of IPv6 addresses is normally
generated.
This field was intended for use where multiple devices may share a
single assigned MAC address and need to have different IPv6 addresses.
T4 VIs each have their own MAC address.

commit df8ef8f3aa
"macvlan: add FDB bridge ops and macvlan flags"
added a way to control NOPROMISC macvlan flag through netlink.
However, with a non passthrough device we never set promisc on open,
even if NOPROMISC is off. As a result:
If userspace clears NOPROMISC on open, then does not clear it on a
netlink command, promisc counter is not decremented on stop and there
will be no way to clear it once macvlan is detached.
If userspace does not clear NOPROMISC on open, then sets NOPROMISC on a
netlink command, promisc counter will be decremented from 0 and overflow
to fffffffff with no way to clear promisc.
To fix, simply ignore NOPROMISC flag in a netlink command for
non-passthrough devices, same as we do at open/close.
Since we touch this code anyway - check dev_set_promiscuity return code
and pass it to users (though an error here is unlikely).

Commit da12c90e09
"netlink: Add compare function for netlink_table"
only set compare at the time we create kernel netlink,
and reset compare to NULL at the time we finially
release netlink socket, but netlink_lookup wants
the compare exist always.
So we should set compare after we allocate nl_table,
and never reset it. make comapre exist all the time.

__GFP_NOWARN is frequently used by kernel code to probe for "how big
an allocation can I get". That's a bit lame, but it's used on slow
paths and is pretty simple.
However, SLAB would still spew a warning when a big allocation happens
if the __GFP_NOWARN flag is _not_ set to expose kernel bugs.

The new XTS code for aesni_intel uses input buffers directly as memory operands
for pxor instructions, which causes crash if those buffers are not aligned to
16 bytes.
Patch changes XTS code to handle unaligned memory correctly, by loading memory
with movdqu instead.
