commit f930c7043663188429cd9b254e9d761edfc101ce upstream.
Don't make any assumptions on the sg_io_hdr_t::dxfer_direction or the
sg_io_hdr_t::dxferp in order to determine if it is a valid request. The
only way we can check for bad requests is by checking if the length
exceeds 256M.

[ Upstream commit bbae08e592706dc32e5c7c97827b13c1c178668b ]
qmi_wwan_disconnect is called twice when disconnecting devices with
separate control and data interfaces. The first invocation will set
the interface data to NULL for both interfaces to flag that the
disconnect has been handled. But the matching NULL check was left
out when qmi_wwan_disconnect was added, resulting in this oops:

[ Upstream commit 0a0e1a85c83775a648041be2b15de6d0a2f2b8eb ]
Commit e5dadc65f9e0 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.
This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.
Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

[ Upstream commit e5dadc65f9e0177eb649bcd9d333f1ebf871223e ]
The global percpu variable ppp_xmit_recursion is used to detect the ppp
xmit recursion to avoid the deadlock, which is caused by one CPU tries to
lock the xmit lock twice. But it would report false recursion when one CPU
wants to send the skb from two different PPP devices, like one L2TP on the
PPPoE. It is a normal case actually.
Now use one percpu member of struct ppp instead of the gloable variable to
detect the xmit recursion of one ppp device.

[ Upstream commit 1daa8790d0280d2c719658e39bd59fce65efa909 ]
Seth Forshee noticed a performance degradation with some workloads.
This turns out to be due to packet drops. Euan Kemp noticed that this
is because we drop all packets where length exceeds the truesize, but
for some packets we add in extra memory without updating the truesize.
This in turn was kept around unchanged from ab7db91705e95 ("virtio-net:
auto-tune mergeable rx buffer size for improved performance"). That
commit had an internal reason not to account for the extra space: not
enough bits to do it. No longer true so let's account for the allocated
length exactly.
Many thanks to Seth Forshee for the report and bisecting and Euan Kemp
for debugging the issue.

[ Upstream commit 7ad813f208533cebfcc32d3d7474dc1677d1b09a ]
Marc reported that he was not getting the PHY library adjust_link()
callback function to run when calling phy_stop() + phy_disconnect()
which does not indeed happen because we set the state machine to
PHY_HALTED but we don't get to run it to process this state past that
point.
Fix this with a synchronous call to phy_state_machine() in order to have
the state machine actually act on PHY_HALTED, set the PHY device's link
down, turn the network device's carrier off and finally call the
adjust_link() function.

[ Upstream commit bcec601f30fb41e9233674942fa4040a6e63657a ]
When adding ethtool steering rule with action DISCARD we wrongly
pass a NULL dest with dest_num 1 to mlx5_add_flow_rules().
What this error seems to have caused is sending VPORT 0
(MLX5_FLOW_DESTINATION_TYPE_VPORT) as the fte dest instead of no dests.
We have fte action correctly set to DROP so it might been ignored
anyways.

On interface remove, the clean-up was done incorrectly causing

[ Upstream commit dc798b4cc0f2a06e7ad7d522403de274b86a0a6f ]
The tx_enabled lag event field is used to determine whether a slave is
active.
Current logic uses this value only if the mode is active-backup.
However, LACP mode, although considered a load balancing mode, can mark
a slave as inactive in certain situations (e.g., LACP timeout).
This fix takes the tx_enabled value into account when remapping, with
no respect to the LAG mode (this should not affect the behavior in XOR
mode, since in this mode both slaves are marked as active).

commit b3743c71b7c33a126d6d8942bb268775987400ec upstream.
For all the entries allocated from the ring cmd area, the memory is
something like the stack memory, which will always reserve the old
data, so the entry->req.iov_bidi_cnt maybe none zero.
On some environments, the crash could be reproduce very easy and some
not. The following is the crash core trace as reported by Damien:

commit cc20ba4ed8576abfa10a17e81cb4521f474624f0 upstream.
The ir-spi driver has 2 issues which prevents it from working with
lirc:
1. The ir-spi driver uses 16 bits of SPI data to create one cycle of
the waveform. As such our SPI clock needs to be 16x faster than the
carrier frequency.
The driver is inconsistent in how it currently handles this. It
initializes it to the carrier frequency:
But the commit message has some example code which initialises it
to 16x the carrier frequency:
val = 608000;
ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val);
To maintain compatibility with lirc, always do the frequency adjustment
in the driver.
2. lirc presents pulses in microseconds, but the ir-spi driver treats
them as cycles of the carrier. Similar to other lirc drivers, do the
conversion with DIV_ROUND_CLOSEST().

commit da05d52d2f0f6bd61094a0cd045fed94bf7d673a upstream.
this patch makes sure VPFE_CMD_S_CCDC_RAW_PARAMS ioctl no longer works
for vpfe_capture driver with a minimal patch suitable for backporting.
- This ioctl was never in public api and was only defined in kernel header.
- The function set_params constantly mixes up pointers and phys_addr_t
numbers.
- This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is
described as an 'experimental ioctl that will change in future kernels'.
- The code to allocate the table never gets called after we copy_from_user
the user input over the kernel settings, and then compare them
for inequality.
- We then go on to use an address provided by user space as both the
__user pointer for input and pass it through phys_to_virt to come up
with a kernel pointer to copy the data to. This looks like a trivially
exploitable root hole.
Due to these reasons we make sure this ioctl now returns -EINVAL and backport
this patch as far as possible.

Since commit e8f4818895b3 ("[media] lirc: advertise
LIRC_CAN_GET_REC_RESOLUTION and improve") lircd uses the ioctl
LIRC_GET_REC_RESOLUTION to determine the shortest pulse or space that
the hardware can detect. This breaks decoding in lirc because lircd
expects the answer in microseconds, but nanoseconds is returned.

commit 9b7c0c476f66ee212925c801c4141fdd83b7336d upstream.
The persistent_config option is used to make the CEC settings persistent by using
the eeprom inside the device to store this information. This was on by default, which
caused confusion since this device now behaves differently from other CEC devices
which all come up unconfigured.
Another reason for doing this now is that I hope a more standard way of selecting
persistent configuration will be created in the future. And for that to work all
CEC drivers should behave the same and come up unconfigured by default.
None of the open source CEC applications are using this CEC framework at the moment
so change this behavior before it is too late.

The previous fix for filtering out of unwatched events was not entirely

interpreted as events with opposing edge.
In order to fix it: always read the GPIO line value on interrupt and
only emit the event if it corresponds with the event type we requested.

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan

intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

commit 0b0f934e92a8eaed2e6c48a50eae6f84661f74f3 upstream.
iwlagn_check_ratid_empty takes the tid as a parameter, but
it doesn't check that it is not IWL_TID_NON_QOS.
Since IWL_TID_NON_QOS = 8 and iwl_priv::tid_data is an array
with 8 entries, accessing iwl_priv::tid_data[IWL_TID_NON_QOS]
is a bad idea.
This happened in iwlagn_rx_reply_tx. Since
iwlagn_check_ratid_empty is relevant only to check whether
we can open A-MPDU, this flow is irrelevant if tid is
IWL_TID_NON_QOS. Call iwlagn_check_ratid_empty only inside
the
if (tid != IWL_TID_NON_QOS)
a few lines earlier in the function.

commit cd069bb9f9ff13b23492fda6ccdb458ac4f641ca upstream.
When LPFC is built-in but NVMe is a loadable module, we fail to link the

We can avoid this either by forcing lpfc to be a module, or by disabling
NVMe support in this case. This implements the former.

systemd by default starts watchdog on reboot and sets the timer to
ShutdownWatchdogSec=10min. Reboot handler in ipmi_watchdog than reduces
the timer to 120s which is not enough time to boot a Xen machine with

during the long run of (XEN) Scrubbing Free RAM.....
Fix this by setting the timer to 120s only if it was previously
set to a low value.

commit 283d6860d64f5091565bf729b0a6d6af14ae6c27 upstream.
The scaler allocation code depends on a non-zero default value for the
crtc scaler_id, so make sure we initialize the scaler state accordingly
even if the crtc is off. This fixes at least an initial YUV420 modeset
(added in a follow-up patchset by Shashank) when booting with the screen
off: after the initial HW readout and modeset which enables the scaler a
subsequent modeset will disable the scaler which isn't properly
allocated. This results in a funky HW state where the pipe scaler HW
registers can't be modified and the normally black screen is grey and
shifted to the right or jitters.
The problem was revealed by Shashank's YUV420 patchset and first
reported by Ville.
