90702dcd19 net: stmmac: fix MAC not working when system resume back with WoL active
We can reproduce this issue with below steps:
1) enable WoL on the host
2) host system suspended
3) remote client send out wakeup packets
We can see that host system resume back, but can't work, such as ping failed.

After a bit digging, this issue is introduced by the commit 46f69ded988d
("net: stmmac: Use resolved link config in mac_link_up()"), which use
the finalised link parameters in mac_link_up() rather than the
parameters in mac_config().

There are two scenarios for MAC suspend/resume in STMMAC driver:

1) MAC suspend with WoL inactive, stmmac_suspend() call
phylink_mac_change() to notify phylink machine that a change in MAC
state, then .mac_link_down callback would be invoked. Further, it will
call phylink_stop() to stop the phylink instance. When MAC resume back,
firstly phylink_start() is called to start the phylink instance, then
call phylink_mac_change() which will finally trigger phylink machine to
invoke .mac_config and .mac_link_up callback. All is fine since
configuration in these two callbacks will be initialized, that means MAC
can restore the state.

2) MAC suspend with WoL active, phylink_mac_change() will put link
down, but there is no phylink_stop() to stop the phylink instance, so it
will link up again, that means .mac_config and .mac_link_up would be
invoked before system suspended. After system resume back, it will do
DMA initialization and SW reset which let MAC lost the hardware setting
(i.e MAC_Configuration register(offset 0x0) is reset). Since link is up
before system suspended, so .mac_link_up would not be invoked after
system resume back, lead to there is no chance to initialize the
configuration in .mac_link_up callback, as a result, MAC can't work any
longer.

After discussed with Russell King [1], we confirm that phylink framework
have not take WoL into consideration yet. This patch calls
phylink_suspend()/phylink_resume() functions which is newly introduced
by Russell King to fix this issue.

0341d5e3d1 net: renesas: sh_eth: Fix freeing wrong tx descriptor
The cur_tx counter must be incremented after TACT bit of
txdesc->status was set. However, a CPU is possible to reorder
instructions and/or memory accesses between cur_tx and
txdesc->status. And then, if TX interrupt happened at such a
timing, the sh_eth_tx_free() may free the descriptor wrongly.
So, add wmb() before cur_tx++.
Otherwise NETDEV WATCHDOG timeout is possible to happen.

be27a47a76 cxgb3: fix oops on module removal
When removing the driver module w/o bringing an interface up before
the error below occurs. Reason seems to be that cancel_work_sync() is
called in t3_sge_stop() for a queue that hasn't been initialized yet.

0a83299935 net: qcom/emac: Replace strlcpy with strscpy
The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.

But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.

Thus, We prefer using strscpy instead of strlcpy.

1b2b918319 bnxt_en: Fix possible unintended driver initiated error recovery
If error recovery is already enabled, bnxt_timer() will periodically
check the heartbeat register and the reset counter.  If we get an
error recovery async. notification from the firmware (e.g. change in
primary/secondary role), we will immediately read and update the
heartbeat register and the reset counter.  If the timer for the next
health check expires soon after this, we may read the heartbeat register
again in quick succession and find that it hasn't changed.  This will
trigger error recovery unintentionally.

The likelihood is small because we also reset fw_health->tmr_counter
which will reset the interval for the next health check.  But the
update is not protected and bnxt_timer() can miss the update and
perform the health check without waiting for the full interval.

Fix it by only reading the heartbeat register and reset counter in
bnxt_async_event_process() if error recovery is trasitioning to the
enabled state.  Also add proper memory barriers so that when enabling
for the first time, bnxt_timer() will see the tmr_counter interval and
perform the health check after the full interval has elapsed.

7ae9dc356f bnxt_en: Fix UDP tunnel logic
The current logic assumes that when the driver sends the message to the
firmware to add the VXLAN or Geneve port, the firmware will never fail
the operation.  The UDP ports are always stored and are used to check
the tunnel packets in .ndo_features_check().  These tunnnel packets
will fail to offload on the transmit side if firmware fails the call to
add the UDP ports.

To fix the problem, bp->vxlan_port and bp->nge_port will only be set to
the offloaded ports when the HWRM_TUNNEL_DST_PORT_ALLOC firmware call
succeeds.  When deleting a UDP port, we check that the port was
previously added successfuly first by checking the FW ID.

This implementation detail permeates into the HWRM API, requiring the

81d0885d68 net: stmmac: Fix overall budget calculation for rxtx_napi
tx_done is not used for napi_complete_done(). Thus, NAPI busy polling
mechanism by gro_flush_timeout and napi_defer_hard_irqs will not able
be triggered after a packet is transmitted when there is no receive
packet.

Fix this by taking the maximum value between tx_done and rx_done as
overall budget completed by the rxtx NAPI poll to ensure XDP Tx ZC
operation is continuously polling for next Tx frame. This gives
benefit of lower packet submission processing latency and jitter
under XDP Tx ZC mode.

Performance of tx-only using xdp-sock on Intel ADL-S platform is
the same with and without this patch.

f1181e39d6 net: cs89x0: disable compile testing on powerpc
The ISA DMA API is inconsistent between architectures, and while
powerpc implements most of what the others have, it does not provide
isa_virt_to_bus():

../drivers/net/ethernet/cirrus/cs89x0.c: In function ‘net_open’:
../drivers/net/ethernet/cirrus/cs89x0.c:897:20: error: implicit declaration of function ‘isa_virt_to_bus’ [-Werror=implicit-function-declaration]

   cs89_dbg(1, debug, "%s: dma %lx %lx\n",

I tried a couple of approaches to handle this consistently across
all architectures, but as this driver is really only used on
ARM, I ended up taking the easy way out and just disable compile
testing on powerpc.

c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

21274aa178 octeontx2-af: Add additional register check to rvu_poll_reg()
Check one more time before exiting the API with an error.
Fix API to poll at least twice, in case there are other high priority
tasks and this API doesn't get CPU cycles for multiple jiffies update.

In addition, increase timeout from usecs_to_jiffies(10000) to
usecs_to_jiffies(20000), to prevent the case that for CONFIG_100HZ
timeout will be a single jiffies.
A single jiffies results actual timeout that can be any time between
1usec and 10msec. To solve this, a value of usecs_to_jiffies(20000)
ensures that timeout is 2 jiffies.

c6132f6f2e bnxt_en: Fix 64-bit doorbell operation on 32-bit kernels
The driver requires 64-bit doorbell writes to be atomic on 32-bit
architectures.  So we redefined writeq as a new macro with spinlock
protection on 32-bit architectures.  This created a new warning when
we added a new file in a recent patchset.  writeq is defined on many
32-bit architectures to do the memory write non-atomically and it
generated a new macro redefined warning.  This warning was fixed
incorrectly in the recent patch.

Fix this properly by adding a new bnxt_writeq() function that will
do the non-atomic write under spinlock on 32-bit systems.  All callers
in the driver will now call bnxt_writeq() instead.

v2: Need to pass in bp to bnxt_writeq()
    Use lo_hi_writeq() [suggested by Florian]

995786ba0d dpaa2-eth: Replace strlcpy with strscpy
The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.

But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.

Thus, We prefer using strscpy instead of strlcpy.

In [1], Christoph Hellwig has proposed to remove the wrappers in

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation
Only relevant parts are given below.

An 'unlikely()' has been removed when calling 'dma_mapping_error()' because
this function, which is inlined, already has such an annotation.
