The commit c6ff5268293ef98e48a99597e765ffc417e39fa5 ("rhashtable:
Fix walker list corruption") causes a suspicious RCU usage warning
because we no longer hold ht->mutex when we dereference ht->tbl.
However, this is a false positive because we now hold ht->lock
which also guarantees that ht->tbl won't disppear from under us.
This patch kills the warning by using rcu_dereference_protected.

FW has a rare corner case in which a fragmented packet using lots
of frags would not be linearized, causing the FW to assert while trying
to transmit the packet.
To prevent this, we need to make sure the window of fragements containing
MSS worth of data contains 1 BD less than for regular packets due to
the additional parsing BD.

When the first request_irq fails in be_msix_register, i value
would be zero. The current code decrements the i value and
accesses the eq object without validating the decremented
"i" value. This can cause an "invalid memory address access"
violation.
This patch fixes the problem by accessing the eq object after
validating the "i" value.

When a fixed-link sub-node exists in a slave node, the slave node
is also the PHY node. Since this is a separate use of the slave node,

Commit 1f71e8c96fc654724723ce987e0a8b2aeb81746d ("drivers: net: cpsw: Add
support for fixed-link PHY") did not parse the "phy-mode" property in
the case of a fixed-link PHY, leaving slave_data->phy_if with its default
of PHY_INTERFACE_MODE_NA(0). This later gets passed to phy_connect() in
cpsw_slave_open(), and eventually to cpsw_phy_sel() where it hits a default
case that configures the MAC for MII mode.
The user visible symptom is that while kernel log messages seem to indicate
that the interface is set up, there is no network communication. Eventually
a watchdog error occurs:

When using more than one slave with ti cpsw and fixed phy the pd->phy_id
will be always zero, but slave_data->phy_id must be unique. pd->phy_id
means a "phy hardware id" whereas slave_data->phy_id means an "unique id",

With b3ca9b02b00704053a38bfe4c31dbbb9c13595d0, the AF_UNIX SOCK_STREAM
receive code was changed from using mutex_lock(&u->readlock) to
mutex_lock_interruptible(&u->readlock) to prevent signals from being
delayed for an indefinite time if a thread sleeping on the mutex
happened to be selected for handling the signal. But this was never a
problem with the stream receive code (as opposed to its datagram
counterpart) as that never went to sleep waiting for new messages with the
mutex held and thus, wouldn't cause secondary readers to block on the
mutex waiting for the sleeping primary reader. As the interruptible
locking makes the code more complicated in exchange for no benefit,
change it back to using mutex_lock.

The Cavium guys reported a soft lockup on their arm64 machine, caused by

do_sys_open+0x14c/0x228
SyS_openat+0x3c/0x48
el0_svc_naked+0x24/0x28
This is because in osq_lock we initialise the node for the current CPU:
node->locked = 0;
node->next = NULL;
node->cpu = curr;
and then publish the current CPU in the lock tail:
old = atomic_xchg_acquire(&lock->tail, curr);
Once the update to lock->tail is visible to another CPU, the node is
then live and can be both read and updated by concurrent lockers.
Unfortunately, the ACQUIRE semantics of the xchg operation mean that
there is no guarantee the contents of the node will be visible before
lock tail is updated. This can lead to lock corruption when, for
example, a concurrent locker races to set the next field.

fou->udp_offloads is managed by RCU. As it is actually included inside

during underrun/collision handling. Within the tx_startup() function
in mac-fcc.c, the address of last BD is not calculated correctly.
As a result of wrong calculation of the last BD address, the next
transmitted BD may be set to an area out of the transmit BD ring.

After commit 15bf176db1fb ("gianfar: Don't enable the Filer w/o the
Parser"), 'TSEC' model controllers (for example as seen on MPC8541E)
always have 8 bytes stripped from the front of received frames.
Only 'eTSEC' gianfar controllers have the RX Filer capability (amongst
other enhancements). Previously this was treated as always enabled
for both 'TSEC' and 'eTSEC' controllers.
In commit 15bf176db1fb ("gianfar: Don't enable the Filer w/o the Parser")
a subtle change was made to the setting of 'uses_rxfcb' to effectively
always set it (since 'rx_filer_enable' was always true). This had the
side-effect of always stripping 8 bytes from the front of received frames
on 'TSEC' type controllers.
We now only enable the RX Filer capability on controller types that
support it, thereby avoiding the issue for 'TSEC' type controllers.

The commit ba7c95ea3870fe7b847466d39a049ab6f156aa2c ("rhashtable:
Fix sleeping inside RCU critical section in walk_stop") introduced
a new spinlock for the walker list. However, it did not convert
all existing users of the list over to the new spin lock. Some
continued to use the old mutext for this purpose. This obviously
led to corruption of the list.
The fix is to use the spin lock everywhere where we touch the list.
This also allows us to do rcu_rad_lock before we take the lock in
rhashtable_walk_start. With the old mutex this would've deadlocked
but it's safe with the new spin lock.

During reprogramming, mac80211 currently first adds all the channel
contexts, then binds them to the vifs and then goes to reconfigure
all the interfaces. Drivers might, perhaps implicitly, rely on the
operation order for certain things that typically happen within a
single function elsewhere in mac80211. To avoid problems with that,
reorder the code in mac80211's restart/reprogramming to work fully
within the interface loop so that the order of operations is like
in normal operation.
For iwlwifi, this fixes a firmware crash when reprogramming with an
AP/GO interface active.

When reconfiguration during resume fails while a scan is pending
for completion work, that work will never run, and the scan will

also in ieee80211_handle_reconfig_failure().

the error goto label lacks the freeing of nd_config.
Fix that.

The first leak occurs when entering the default case
in the switch for the initiator in set_regdom.
The second leaks a platform_device struct if the
platform registration in regulatory_init succeeds but
the sub sequent regulatory hint fails due to no memory.
