Using gcov to collect coverage data for kernels compiled with GCC 10.1
causes random malfunctions and kernel crashes. This is the result of a
changed GCOV_COUNTERS value in GCC 10.1 that causes a mismatch between
the layout of the gcov_info structure created by GCC profiling code and
the related structure used by the kernel.
Fix this by updating the in-kernel GCOV_COUNTERS value. Also re-enable
config GCOV_KERNEL for use with GCC 10.

ASoC: Fixes for v5.9
Most of this is various driver specific fixes, none of which are
terribly exciting in themselves, plus one core fix adding and using a
new DAI lookup function to deal with a lockdep warning.

The arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi device tree lacks DMA
channels for DSPI, so naturally, the driver fails to probe:
[ 2.945302] fsl-dspi 2100000.spi: rx dma channel not available
[ 2.951134] fsl-dspi 2100000.spi: can't get dma channels
In retrospect, this should have been obvious, because LS2080A, LS2085A
LS2088A and LX2160A don't appear to have an eDMA module at all. Looking
again at their datasheets, the CTARE register (which is specific to XSPI
functionality) seems to be documented, so switch them to XSPI mode
instead.

The parameter passed via DCB_ATTR_DCB_BUFFER is a struct dcbnl_buffer. The
field prio2buffer is an array of IEEE_8021Q_MAX_PRIORITIES bytes, where
each value is a number of a buffer to direct that priority's traffic to.
That value is however never validated to lie within the bounds set by
DCBX_MAX_BUFFERS. The only driver that currently implements the callback is
mlx5 (maintainers CCd), and that does not do any validation either, in
particual allowing incorrect configuration if the prio2buffer value does
not fit into 4 bits.
Instead of offloading the need to validate the buffer index to drivers, do
it right there in core, and bounce the request if the value is too large.

When a netdev is enslaved to a bridge, its parent identifier is queried.
This is done so that packets that were already forwarded in hardware
will not be forwarded again by the bridge device between netdevs
belonging to the same hardware instance.
The operation fails when the netdev is an upper of netdevs with
different parent identifiers.
Instead of failing the enslavement, have dev_get_port_parent_id() return
'-EOPNOTSUPP' which will signal the bridge to skip the query operation.
Other callers of the function are not affected by this change.

There are a couple bugs here:
1) If opt[1] is zero then this results in a forever loop. If the value
is less than 2 then it is invalid.
2) It assumes that "len" is more than sizeof(valid_accm) or 6 which can
result in memory corruption.
In the case of LCP_OPTION_ACCM, then we should check "opt[1]" instead
of "len" because, if "opt[1]" is less than sizeof(valid_accm) then
"nak_len" gets out of sync and it can lead to memory corruption in the
next iterations through the loop. In case of LCP_OPTION_MAGIC, the
only valid value for opt[1] is 6, but the code is trying to log invalid
data so we should only discard the data when "len" is less than 6
because that leads to a read overflow.

Since the micrel phy driver calls phy_init_hw() as a workaround,
the commit 9886a4dbd2aa ("net: phy: call phy_disable_interrupts()
in phy_init_hw()") disables the interrupt unexpectedly. So,
call phy_disable_interrupts() in phy_attach_direct() instead.
Otherwise, the phy cannot link up after the ethernet cable was
disconnected.
Note that other drivers (like at803x.c) also calls phy_init_hw().
So, perhaps, the driver caused a similar issue too.

Currently there is concurrent reset and enqueue operation for the
same lockless qdisc when there is no lock to synchronize the
q->enqueue() in __dev_xmit_skb() with the qdisc reset operation in
qdisc_deactivate() called by dev_deactivate_queue(), which may cause
out-of-bounds access for priv->ring[] in hns3 driver if user has
requested a smaller queue num when __dev_xmit_skb() still enqueue a
skb with a larger queue_mapping after the corresponding qdisc is
reset, and call hns3_nic_net_xmit() with that skb later.
Reused the existing synchronize_net() in dev_deactivate_many() to
make sure skb with larger queue_mapping enqueued to old qdisc(which
is saved in dev_queue->qdisc_sleeping) will always be reset when
dev_reset_queue() is called.

In mptcp_pm_nl_get_local_id, skc_local is the same as msk_local, so it
always return 0. Thus every subflow's local_id is 0. It's incorrect.
This patch fixed this issue.
Also, we need to ignore the zero address here, like 0.0.0.0 in IPv4. When
we use the zero address as a local address, it means that we can use any
one of the local addresses. The zero address is not a new address, we don't
need to add it to PM, so this patch added a new function address_zero to
check whether an address is the zero address, if it is, we ignore this
address.

I confirmed that the problem fixed by commit 2a63866c8b51a3f7 ("tipc: fix
shutdown() of connectionless socket") also applies to stream socket.
----------
#include <sys/socket.h>
#include <unistd.h>
#include <sys/wait.h>
int main(int argc, char *argv[])
{
int fds[2] = { -1, -1 };
socketpair(PF_TIPC, SOCK_STREAM /* or SOCK_DGRAM */, 0, fds);
if (fork() == 0)
_exit(read(fds[0], NULL, 1));
shutdown(fds[0], SHUT_RDWR); /* This must make read() return. */
wait(NULL); /* To be woken up by _exit(). */
return 0;
}
----------
Since shutdown(SHUT_RDWR) should affect all processes sharing that socket,
unconditionally setting sk->sk_shutdown to SHUTDOWN_MASK will be the right
behavior.

This reverts commit 14775b04964264189caa4a0862eac05dab8c0502 as there
were still some parsing problems with it, and the follow-on patch for
it.
Let's revisit it later, just drop it for now.

This reverts commit 42f07816ac0cc797928119cc039c414ae2b95d34 as it

can also revert the original patch this was supposed to be helping with.

On non-EFI systems, it wasn't possible to test the platform firmware
loader because it will have never set "checked_fw" during __init.
Instead, allow the test code to override this check. Additionally split
the declarations into a private symbol namespace so there is greater
enforcement of the symbol visibility.

For some inexplicable reason I decided to call flush_scheduled_work()
instead of cancel_delayed_work_sync(). The problem with that is that
flush_scheduled_work() waits for *all* queued scheduled work to be
completed instead of just the work itself.
This can cause a deadlock if a CEC driver also schedules work that
takes the same lock. See the comments for flush_scheduled_work() in
linux/workqueue.h.
This is exactly what has been observed a few times.
This patch simply replaces flush_scheduled_work() by
cancel_delayed_work_sync().

Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node, however when control is
transferred from the middle of the loop, as in the case of a return
or break or goto, there is no decrement thus ultimately resulting in
a memory leak.
Fix a potential memory leak in clk-impd1.c by inserting
of_node_put() before a return statement.
Issue found with Coccinelle.

In sas_notify_lldd_dev_found(), if we can't allocate the necessary
resources, then it seems like the wrong thing to mark the device as found
and to increment the reference count. None of the callers ever drop the
reference in that situation.

When timestamping a packet there's a delay between the start of the
packet and the point where the hardware actually captures the
timestamp. This difference needs to be considered if we want accurate
timestamps.
This was done on the RX side, but not on the TX side.

interpolating the i210 numbers with the i225 crystal clock value. That

The for loop in i40e_set_vsi_promisc() reports errors via dev_err() but
does not propagate the error up the call chain. Instead it continues the
loop and potentially overwrites the reported error value.
This results in the error being recorded in the log buffer, but the
caller might never know anything went the wrong way.
To avoid this situation i40e_set_vsi_promisc() needs to temporarily store
the error after reporting it. This is still not optimal as multiple
different errors may occur, so store the first error and hope that's
the main issue.
