commit 5c089fd0c73411f2170ab795c9ffc16718c7d007 upstream.
If the entry is deleted from the IDR between the call to
radix_tree_iter_find() and rcu_dereference_raw(), idr_get_next()
will return NULL, which will end the iteration prematurely. We should
instead continue to the next entry in the IDR. This only happens if the
iteration is protected by the RCU lock. Most IDR users use a spinlock
or semaphore to exclude simultaneous modifications. It was noticed once
the PID allocator was converted to use the IDR, as it uses the RCU lock,
but there may be other users elsewhere in the kernel.
We can't use the normal pattern of calling radix_tree_deref_retry()
(which catches both a retry entry in a leaf node and a node entry in
the root) as the IDR supports storing entries which are unaligned,
which will trigger an infinite loop if they are encountered. Instead,
we have to explicitly check whether the entry is a retry entry.

commit a56dcc6b455830776899ce3686735f1172e12243 upstream.
This code is supposed to test for negative error codes and partial
reads, but because sizeof() is size_t (unsigned) type then negative
error codes are type promoted to high positive values and the condition
doesn't work as expected.

iptables -t mangle -A PREROUTING -m state --state ESTABLISHED -j ACCEPT
iptables -t mangle -P PREROUTING DROP
When deleting a secondary address, current masquerade implements would
flush all conntracks on this device. All the established connections on
primary address also be deleted, then subsequent incoming data on the
connections would be dropped wrongly because it was identified as NEW

So when an address was delete, it should only flush connections related

We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.
When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.
We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.
To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

[ Upstream commit 6323d57f335ce1490d025cacc83fc10b07792130 ]
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

If we went into sas_rediscover_dev() the attached_sas_addr was already insured
not to be zero. So it's unnecessary to check if the attached_sas_addr is zero.
And although if the sas address is not changed, we always have to unregister
the old device when we are going to register a new one. We cannot just leave
the device there and bring up the new.

The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support. It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace. Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.
As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

The function should return -EFAULT when copy_from_user fails. Even
though the caller does not distinguish them. but we should keep backward
compatibility.

kgdbts current fails when compiled with restrict:
drivers/misc/kgdbts.c: In function ‘configure_kgdbts’:
drivers/misc/kgdbts.c:1070:2: error: ‘strcpy’ source argument is the same as destination [-Werror=restrict]
strcpy(config, opt);
^~~~~~~~~~~~~~~~~~~
As the error says, config is being used in both the source and destination.
Refactor the code to avoid the extra copy and put the parsing closer to
the actual location.
