In commit d999297c3d
("tipc: reduce locking scope during packet reception") we introduced
a new function tipc_build_bcast_sync_msg(), which carries initial
synchronization data between two nodes at first contact and at
re-contact. In this function, we missed to add synchronization data,
with the effect that the broadcast link endpoints will fail to
synchronize correctly at re-contact between a running and a restarted
node. All other cases work as intended.
With this commit, we fix this bug.

Since mdb states were introduced when deleting an entry the state was
left as it was set in the delete request from the user which leads to
the following output when doing a monitor (for example):
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 temp
^^^
Note the "temp" state in the delete notification which is wrong since
the entry was permanent, the state in a delete is always reported as
"temp" regardless of the real state of the entry.
After this patch:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
There's one important note to make here that the state is actually not
matched when doing a delete, so one can delete a permanent entry by
stating "temp" in the end of the command, I've chosen this fix in order
not to break user-space tools which rely on this (incorrect) behaviour.
So to give an example after this patch and using the wrong state:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 temp
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
Note the state of the entry that got deleted is correct in the
notification.

Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop
via helper functions. These functions may change skb->data/hlen.
This data is cached by s390 JIT to improve performance of ld_abs/ld_ind
instructions. Therefore after a change we have to reload the data.
In case of usage of skb_vlan_push/pop, in the prologue we store
the SKB pointer on the stack and restore it after BPF_JMP_CALL
to skb_vlan_push/pop.

Currently we have the restriction that jitted BPF programs can
have a maximum size of one page. The reason is that we use short
displacements for the literal pool.
The 20 bit displacements are available since z990 and BPF requires
z196 as minimum. Therefore we can remove this restriction and use
everywhere 20 bit signed long displacements.

The EMIT6_DISP_LH macro passes the "disp" parameter to the _EMIT6_DISP_LH
macro. The _EMIT6_DISP_LH macro uses the "disp" parameter twice:
unsigned int __disp_h = ((u32)disp) & 0xff000;
unsigned int __disp_l = ((u32)disp) & 0x00fff;
The EMIT6_DISP_LH is used several times with EMIT_CONST_U64() as "disp"
parameter. Therefore always two constants are created per usage of
EMIT6_DISP_LH.
Fix this and add variable "_disp" to avoid multiple expansions.

Currently we assumed the following BPF to eBPF register mapping:

- BPF_REG_X -> BPF_REG_8
Unfortunately this mapping is wrong. The correct mapping is:
- BPF_REG_A -> BPF_REG_0
- BPF_REG_X -> BPF_REG_7
So clear the correct registers and use the BPF_REG_A and BPF_REG_X
macros instead of BPF_REG_0/7.

When (multiple) vlan tagged packets with CHECKSUM_PARTIAL are forwarded

error because before entering bridge, the network header is set to
ETH_HLEN (not including vlan header length) in __netif_receive_skb_core(),

Fix this by accounting for the call to prealloc_data_structs()

This reverts commit 386cb7cdee.
Taking the wake_worker() out of free_migration() will slow writeback
dramatically, and hence adaptability.
Say we have 10k blocks that need writing back, but are only able to
issue 5 concurrently due to the migration bandwidth: it's imperative
that we wake_worker() immediately after migration completion; waiting
for the next 1 second wake up (via do_waker) means it'll take a long
time to write that all back.

cryptmode:
0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
encapsulation to the firmware. This is the default mode.
1: Use sofware crypto engine globally with raw mode TX/RX
encapsulation to the firmware.
Known limitation:
A-MSDU must be disabled for RAW Tx encap mode to perform well when
heavy traffic is applied.

When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.
This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.
DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

stmmac clean up for 4.3 part2
This patch set creates proper probe functions in the remaining
dwmac-* drivers, lets the drivers manage their own of match data
structure, and cleans up some of the drivers a bit. Note that
should be no functional change in any of the drivers.
First patch from Fengguang fixes a Coccinelle that was found after
the previous patch set when into next.
Probe functions are best placed just above the platform_driver
struct since it usually needs to call other functions in the
driver but this requires some code movement in the drivers. To
keep the conversion itself easier to review the code movement is
done in separate patches. This creates some extra churn but I
think it's worth it in this case.
As only a couple of drivers actually needs to use of match data
this pushed down from stmmac_platform and into the drivers. This
also makes it possible for drivers to have their own match data
structure. dwmac-rk benefits most from this.
After each driver has it's own probe function and manages it's
own match data the setup/free hooks and common match data struct
are removed.
Sorry for the slightly largish patch set this time around.
Since I can only test the core changes on my platform and not the
specific dwmac-drivers I greatly appreciate if people could test
this on their respective platforms. I did spend quite a bit of
time visually checking all these patches, but nothing beats real
hardware testing. Thanks!

Remove the two platform specific init callbacks and make
them use a common one by creating a function member in
the internal data structure. This allow us to remove the
layer of indirection and simplify the code a bit.

As all dwmac-* drivers have been converted to have a proper probe
function the setup callback can now be removed. Also remove the
free callback that wasn't used by any driver.
New dwmac-* drivers should implement standard probe and remove
functions to preform any needed setup and teardown.

Remove the setup glue callback and use rk_gmac_ops as OF match
data so it can used directly when calling rk_gmac_setup.

Create a new private structure for OF match data in the
dwmac-sti driver. This enables us to eventually drop the
common OF match data structure which contains a lot of
unused fields.

Since only a few of the dwmac-* drivers actually need to use
the OF match move handling into the dwmac-* drivers that need
it. This will also allow dwmac-* drivers to use their own
custom match data structure.
