[ Upstream commit f11999987bc0b5559ab56dedc6f4ca32fab5438a ]
Clean the whole mac filter list when resetting after an intermediate
add or delete push to the firmware. The code had evolved from using
a list from the stack to a heap allocation, but the memset() didn't
follow the change correctly. This now cleans the whole list rather
that just part of the first element.

[ Upstream commit fdb47ae87af537b24977a03bc69cfe1c5c55ca62 ]
If the driver gets unloaded during reset recovery, it's possible
that it will attempt to free resources when they're already free.
Add a check to make sure that the Tx and Rx rings actually exist
before dereferencing them to free resources.

[ Upstream commit b7b713a8eaf325607d37229f024ad0b9f3e7f320 ]
When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.
Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.

[ Upstream commit b36e9ab59b7e3a5b14bf88dc0536e6579db7b54d ]
The virtual channel interface was using incorrect semantics to remove
MAC addresses, which would leave incorrect filters active when using
VLANs. To correct this, add a new function that unconditionally removes
MAC addresses from all VLANs, and call this function when the VF
requests a MAC filter removal.

[ Upstream commit a42e7a369ea2b73a554a85dea7d6243af51cd4f0 ]
This patch fixes the memory leak which would be seen otherwise when user
programs flow-director filter using ethtool (sideband filter programming).
When ethtool is used to program flow directory filter, 'raw_buf' gets
allocated and it is supposed to be freed as part of queue cleanup. But
check of 'tx_buffer->skb' was preventing it from being freed.

[ Upstream commit 0e4425ed641f3eef67c892bc541949cd745a9ba9 ]
The driver was being called by VLAN, bonding, teaming operations
that expected to be able to hold locks like rcu_read_lock().
This causes the driver to be held to the requirement to not sleep,
and was found by the kernel debug options for checking sleep
inside critical section, and the locking validator.

[ Upstream commit 6a7fded776a778f728b13d83a2c9fc893580c080 ]
This patch fixes the issue of forcing WB too often causing us to not
benefit from NAPI.
Without this patch we were forcing WB/arming interrupt too often taking
away the benefits of NAPI and causing a performance impact.
With this patch we disable force WB in the clean routine for X710
and XL710 adapters. X722 adapters do not enable interrupt to force
a WB and benefit from WB_ON_ITR and hence force WB is left enabled
for those adapters.
For XL710 and X710 adapters if we have less than 4 packets pending
a software Interrupt triggered from service task will force a WB.
This patch also changes the conditions for setting RS bit as described
in code comments. This optimizes when the HW does a tail bump amd when
it does a WB. It also optimizes when we do a wmb.

[ Upstream commit 1418c3458118c6969d08e23aa377da7e2a7be36c ]
When a lot (many hundreds) of MAC or VLAN filters are added at one time,
we can overflow the Admin Queue buffer size with all the requests.
Unfortunately, the driver would then calculate the message size
incorrectly, causing it to be rejected by the PF. Furthermore, there was
no mechanism to trigger another request to allow for configuring the
rest of the filters that didn't fit into the first request.
To fix this, recalculate the correct buffer size when we detect the
overflow condition instead of just assuming the max buffer size. Also,
don't clear the request bit in adapter->aq_required when we have an
overflow, so that the rest of the filters can be processed later.

commit 702b07fcc9b264c9afd372676bbdd50a762dcde0 upstream.
SRAT maps APIC ID to proximity domains ids (PXM). Mapping from PXM to
NUMA node ids is based on order of entries in SRAT table.
SRAT table has just LAPIC entires or mix of LAPIC and X2APIC entries.
As long as there are only LAPIC entires, mapping from proximity domain
id to NUMA node id is as assumed by BIOS. However, once APIC entries are
mixed, X2APIC entries would be first mapped which causes unexpected NUMA
node mapping.
To fix that, change parsing to check each entry against both LAPIC and
X2APIC so mapping is in the SRAT/PXM order.
This is supplemental change to the fix made by commit d81056b5278
(Handle apic/x2apic entries in MADT in correct order) and using the
mechanism introduced by 9b3fedd (ACPI / tables: Add acpi_subtable_proc
to ACPI table parsers).

commit 5331d9cab32ef640b4cd38a43b0858874fbb7168 upstream.
Commit e647b532275b ("ACPI: Add early device probing infrastructure")
introduced code that allows inserting driver specific
struct acpi_probe_entry probe entries into ACPI linker sections
(one per-subsystem, eg irqchip, clocksource) that are then walked
to retrieve the data and function hooks required to probe the
respective kernel components.
Probing for all entries in a section is triggered through
the __acpi_probe_device_table() function, that in turn, according
to the table ID a given probe entry reports parses the table
with the function retrieved from the respective section structures
(ie struct acpi_probe_entry). Owing to the current ACPI table
parsing implementation, the __acpi_probe_device_table() function
has to share global variables with the acpi_match_madt() function, so
in order to guarantee mutual exclusion locking is required
between the two functions.
Current kernel code implements the locking through the acpi_probe_lock
spinlock; this has the side effect of requiring all code called
within the lock (ie struct acpi_probe_entry.probe_{table/subtbl} hooks)
not to sleep.
However, kernel subsystems that make use of the early probing
infrastructure are relying on kernel APIs that may sleep (eg
irq_domain_alloc_fwnode(), among others) in the function calls
pointed at by struct acpi_probe_entry.{probe_table/subtbl} entries
(eg gic_v2_acpi_init()), which is a bug.
Since __acpi_probe_device_table() is called from context
that is allowed to sleep the acpi_probe_lock spinlock can be replaced
with a mutex; this fixes the issue whilst still guaranteeing
mutual exclusion.

commit f0f4b0cc3a8cffd983f5940d46cd0227f3f5710a upstream.
Commit ebb657babfa9 ("staging: comedi: ni_mio_common: clarify the
cmd->start_arg validation and use") introduced a backwards compatibility
issue in the use of asynchronous commands on the AO subdevice when
`start_src` is `TRIG_EXT`. Valid values for `start_src` are `TRIG_INT`
(for internal, software trigger), and `TRIG_EXT` (for external trigger).
When set to `TRIG_EXT`. In both cases, the driver relies on an
internal, software trigger to set things up (allowing the user
application to write sufficient samples to the data buffer before the
trigger), so it acts as a software "pre-trigger" in the `TRIG_EXT` case.
The software trigger is handled by `ni_ao_inttrig()`.
Prior to the above change, when `start_src` was `TRIG_INT`, `start_arg`
was required to be 0, and `ni_ao_inttrig()` checked that the software
trigger number was also 0. After the above change, when `start_src` was
`TRIG_INT`, any value was allowed for `start_arg`, and `ni_ao_inttrig()`
checked that the software trigger number matched this `start_arg` value.
The backwards compatibility issue is that the internal trigger number
now has to match `start_arg` when `start_src` is `TRIG_EXT` when it
previously had to be 0.
Fix the backwards compatibility issue in `ni_ao_inttrig()` by always
allowing software trigger number 0 when `start_src` is something other
than `TRIG_INT`.
Thanks to Spencer Olson for reporting the issue.

commit 403fe7f34e3327ddac2e06a15e76a293d613381e upstream.
Commit 73e0e4dfed4c ("staging: comedi: comedi_test: fix timer lock-up")
fixed a lock-up in the timer routine `waveform_ai_timer()` (which was
called `waveform_ai_interrupt()` at the time) caused by
commit 240512474424 ("staging: comedi: comedi_test: use
comedi_handle_events()"). However, it introduced a race condition that
can result in the timer routine misbehaving, such as accessing freed
memory or dereferencing a NULL pointer.
73e0... changed the timer routine to do nothing unless a
`WAVEFORM_AI_RUNNING` flag was set, and changed `waveform_ai_cancel()`
to clear the flag and replace a call to `del_timer_sync()` with a call
to `del_timer()`. `waveform_ai_cancel()` may be called from the timer
routine itself (via `comedi_handle_events()`), or from `do_cancel()`.
(`do_cancel()` is called as a result of a file operation (usually a
`COMEDI_CANCEL` ioctl command, or a release), or during device removal.)
When called from `do_cancel()`, the call to `waveform_ai_cancel()` is
followed by a call to `do_become_nonbusy()`, which frees up stuff for
the current asynchronous command under the assumption that it is now
safe to do so. The race condition occurs when the timer routine
`waveform_ai_timer()` checks the `WAVEFORM_AI_RUNNING` flag just before
it is cleared by `waveform_ai_cancel()`, and is still running during the
call to `do_become_nonbusy()`. In particular, it can lead to a NULL
pointer dereference:
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<ffffffffc0c63add>] waveform_ai_timer+0x17d/0x290 [comedi_test]
That corresponds to this line in `waveform_ai_timer()`:
unsigned int chanspec = cmd->chanlist[async->cur_chan];
but `do_become_nonbusy()` frees `cmd->chanlist` and sets it to `NULL`.
Fix the race by calling `del_timer_sync()` instead of `del_timer()` in
`waveform_ai_cancel()` when not in an interrupt context. The only time
`waveform_ai_cancel()` is called in an interrupt context is when it is
called from the timer routine itself, via `comedi_handle_events()`.
There is no longer any need for the `WAVEFORM_AI_RUNNING` flag, so get
rid of it.
The bug was copied from the AI subdevice to the AO when support for
commands on the AO subdevice was added by commit 0cf55bbef2f9 ("staging:
comedi: comedi_test: implement commands on AO subdevice"). That
involves the timer routine `waveform_ao_timer()`, the comedi "cancel"
routine `waveform_ao_cancel()`, and the flag `WAVEFORM_AO_RUNNING`. Fix
it in the same way as for the AI subdevice.

commit 53e5f36fbd2453ad69a3369a1db62dc06c30a4aa upstream.
UBSAN complains about a left shift by -1 in proc_do_submiturb(). This
can occur when an URB is submitted for a bulk or control endpoint on
a high-speed device, since the code doesn't bother to check the
endpoint type; normally only interrupt or isochronous endpoints have
a nonzero bInterval value.
Aside from the fact that the operation is illegal, it shouldn't matter
because the result isn't used. Still, in theory it could cause a
hardware exception or other problem, so we should work around it.
This patch avoids doing the left shift unless the shift amount is >= 0.
The same piece of code has another problem. When checking the device
speed (the exponential encoding for interrupt endpoints is used only
by high-speed or faster devices), we need to look for speed >=
USB_SPEED_SUPER as well as speed == USB_SPEED HIGH. The patch adds
this check.

commit e514cc0a492a3f39ef71b31590a7ef67537ee04b upstream.
The props->ap[] array is defined like this:
struct alg_props ap[NX_MAX_FC][NX_MAX_MODE][3];
So we can see that if msc->fc and msc->mode are == to NX_MAX_FC or
NX_MAX_MODE then we're off by one.

commit 47af45d684b5f3ae000ad448db02ce4f13f73273 upstream.
The commit 4097461897df ("Input: i8042 - break load dependency ...")
correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do
the same for AUX port(s), which results in communication on KBD and AUX
ports to clash with each other.

commit 4097461897df91041382ff6fcd2bfa7ee6b2448c upstream.
As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.
> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c. atkbd.c depends on libps2.c because it invokes
> ps2_command(). libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner(). As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)
To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

commit 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 upstream.
The UserMode (UM) Linux build was failing in gpiolib-of as it requires
ioremap()/iounmap() to exist, which is absent from UM. The non-existence
of IO memory is negatively defined as CONFIG_NO_IOMEM which means we
need to depend on HAS_IOMEM.

commit 4d01d88019261d05ec3bff5f1a6013393faa3b9e upstream.
cros_ec_cmd_xfer returns success status if the command transport
completes successfully, but the execution result is incorrectly ignored.
In many cases, the execution result is assumed to be successful, leading
to ignored errors and operating on uninitialized data.
We've recently introduced the cros_ec_cmd_xfer_status() helper to avoid these
problems. Let's use it.
[Regarding the 'Fixes' tag; there is significant refactoring since the driver's
introduction, but the underlying logical error exists throughout I believe]

commit fa00c437eef8dc2e7b25f8cd868cfa405fcc2bb3 upstream.
In aacraid's ioctl_send_fib() we do two fetches from userspace, one the
get the fib header's size and one for the fib itself. Later we use the
size field from the second fetch to further process the fib. If for some
reason the size from the second fetch is different than from the first
fix, we may encounter an out-of- bounds access in aac_fib_send(). We
also check the sender size to insure it is not out of bounds. This was
reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was
assigned CVE-2016-6480.

commit 34276bb062b8449b3b0a208c9b848a1a27920075 upstream.
The called of_graph_get_next_endpoint() already decrements the refcount
of the prev node, so it is wrong to do it again in the calling function.
Use the for_each_endpoint_of_node() helper to interate through the
endpoint OF nodes, which already does the right thing and simplifies
the code a bit.

commit 9ba333dc55cbb9523553df973adb3024d223e905 upstream.
When a device is in a status where CIO has killed all I/O by itself the
interrupt for a clear request may not contain an irb to determine the
clear function. Instead it contains an error pointer -EIO.
This was ignored by the DASD int_handler leading to a hanging device
waiting for a clear interrupt.
Handle -EIO error pointer correctly for requests that are clear pending and
treat the clear as successful.

commit 8cf4345575a416e6856a6856ac6eaa31ad883126 upstream.
In the function amd_gpio_irq_enable() and
amd_gpio_direction_input(), remove the code which is setting
the default de-bounce time to 2.75ms.
The driver code shall use the same settings as specified in
BIOS. Any default assignment impacts TouchPad behaviour when
the LevelTrig is set to EDGE FALLING.
