In case of im_protocols value is 1 and tm_protocols value is 0 this
combination successfully passes the check
'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
But then after pn533_poll_create_mod_list() call in pn533_start_poll()
poll mod list will remain empty and dev->poll_mod_count will remain 0
which lead to division by zero.
Normally no im protocol has value 1 in the mask, so this combination is
not expected by driver. But these protocol values actually come from
userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
broken or malicious program may pass a message containing a "bad"
combination of protocol parameter values so that dev->poll_mod_count
is not incremented inside pn533_poll_create_mod_list(), thus leading
to division by zero.
Call trace looks like:
nfc_genl_start_poll()
nfc_start_poll()
->start_poll()
pn533_start_poll()
Add poll mod list filling check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
NULL pointer, but its callers only check for error pointers thus miss
the NULL pointer case.
Fix it by returning an error pointer with the error code carried from
sockfd_lookup().
(I found this bug during code inspection.)

In the cited commit, bond->ipsec_lock is added to protect ipsec_list,
hence xdo_dev_state_add and xdo_dev_state_delete are called inside
this lock. As ipsec_lock is a spin lock and such xfrmdev ops may sleep,
"scheduling while atomic" will be triggered when changing bond's
active slave.

As bond_ipsec_add_sa_all and bond_ipsec_del_sa_all are only called
from bond_change_active_slave, which requires holding the RTNL lock.
And bond_ipsec_add_sa and bond_ipsec_del_sa are xfrm state
xdo_dev_state_add and xdo_dev_state_delete APIs, which are in user
context. So ipsec_lock doesn't have to be spin lock, change it to
mutex, and thus the above issue can be resolved.

Add this implementation for bonding, so hardware resources can be
freed from the active slave after xfrm state is deleted. The netdev
used to invoke xdo_dev_state_free callback, is saved in the xfrm state
(xs->xso.real_dev), which is also the bond's active slave. To prevent
it from being freed, acquire netdev reference before leaving RCU
read-side critical section, and release it after callback is done.
And call it when deleting all SAs from old active real interface while
switching current active slave.

With recent work to the doorbell workaround code a small hole was
introduced that could cause a tx_timeout. This happens if the rx
dbell_deadline goes beyond the netdev watchdog timeout set by the driver
(i.e. 2 seconds). Fix this by changing the netdev watchdog timeout to 5
seconds and reduce the max rx dbell_deadline to 4 seconds.
The test that can reproduce the issue being fixed is a multi-queue send
test via pktgen with the "burst" setting to 1. This causes the queue's
doorbell to be rung on every packet sent to the driver, which may result
in the device missing doorbells due to the high doorbell rate.

When the firmware crashes, we first told the op_mode and only then,
changed the transport's state. This is a problem if the op_mode's
nic_error() handler needs to send a host command: it'll see that the
transport's state still reflects that the firmware is alive.
Today, this has no consequences since we set the STATUS_FW_ERROR bit and
that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording
looks at this bit to know not to send a host command for example.
To fix the hibernation, we needed to reset the firmware without having
an error and checking STATUS_FW_ERROR to see whether the firmware is
alive will no longer hold, so this change is necessary as well.
Change the flow a bit.
Change trans->state before calling the op_mode's nic_error() method and
check trans->state instead of STATUS_FW_ERROR. This will keep the
current behavior of iwl_fw_dbg_stop_restart_recording upon firmware
error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording
safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not
alive.

There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.
Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.

Fast resume is a feature that was recently introduced to speed up the
resume time. It basically keeps the firmware alive while the system
is suspended and that avoids starting again the whole device.
This flow can't work for hibernation, since when the system boots,
before the frozen image is loaded, the kernel may touch the device. As a
result, we can't assume the device is in the exact same state as before
the hibernation.
Detect that we are resuming from hibernation through the PCI device and
forbid the fast resume flow. We also need to shut down the device
cleanly when that happens.
In addition, in case the device is power gated during S3, we won't be
able to keep the device alive. Detect this situation with BE200 at least
with the help of the CSR_FUNC_SCRATCH register and reset the device upon
resume if it was power gated during S3.

This fixes the random kernel crash seen while removing the driver, when

1) modprobe btnxpuart
2) hciconfig hci0 reset
3) hciconfig (check hci0 interface up with valid BD address)
4) modprobe -r btnxpuart
Repeat steps 1 to 4
The ps_wakeup() call in btnxpuart_close() schedules the psdata->work(),
which gets scheduled after module is removed, causing a kernel crash.
This hidden issue got highlighted after enabling Power Save by default
in 4183a7be7700 (Bluetooth: btnxpuart: Enable Power Save feature on

BRI (Bluetooth Radio Interface) traffic from CNVr to CNVi was found causing
cross talk step errors to WiFi. To avoid this potential issue OEM platforms
can replace BRI resistor to adjust the BRI response line drive strength.
During the *setup*, driver reads the drive strength value from uefi
variable and passes it to the controller via vendor specific command with
opcode 0xfc0a.

The mana_hwc_rx_event_handler() / mana_hwc_handle_resp() calls
complete(&ctx->comp_event) before posting the wqe back. It's
possible that other callers, like mana_create_txq(), start the
next round of mana_hwc_send_request() before the posting of wqe.
And if the HW is fast enough to respond, it can hit no_wqe error
on the HW channel, then the response message is lost. The mana
driver may fail to create queues and open, because of waiting for
the HW response and timed out.
Sample dmesg:
[ 528.610840] mana 39d4:00:02.0: HWC: Request timed out!
[ 528.614452] mana 39d4:00:02.0: Failed to send mana message: -110, 0x0
[ 528.618326] mana 39d4:00:02.0 enP14804s2: Failed to create WQ object: -110
To fix it, move posting of rx wqe before complete(&ctx->comp_event).

Some CPT AF registers are per LF and others are global. Translation
of PF/VF local LF slot number to actual LF slot number is required
only for accessing perf LF registers. CPT AF global registers access
do not require any LF slot number. Also, there is no reason CPT
PF/VF to know actual lf's register offset.
Without this fix microcode loading will fail, VFs cannot be created
and hardware is not usable.

The current implementation incorrectly sets the mode bit of the PHY chip.
Bit 15 (RTL8211F_LEDCR_MODE) should not be shifted together with the
configuration nibble of a LED- it should be set independently of the
index of the LED being configured.
As a consequence, the RTL8211F LED control is actually operating in Mode A.
Fix the error by or-ing final register value to write with a const-value of
RTL8211F_LEDCR_MODE, thus setting Mode bit explicitly.

When performing the port_hwtstamp_set operation, ptp_schedule_worker()
will be called if hardware timestamoing is enabled on any of the ports.
When using multiple ports for PTP, port_hwtstamp_set is executed for
each port. When called for the first time ptp_schedule_worker() returns
0. On subsequent calls it returns 1, indicating the worker is already
scheduled. Currently the ksz driver treats 1 as an error and fails to
complete the port_hwtstamp_set operation, thus leaving the timestamping
configuration for those ports unchanged.
This patch fixes this by ignoring the ptp_schedule_worker() return
value.

Sabrina reports that the igb driver does not cope well with large
MAX_SKB_FRAG values: setting MAX_SKB_FRAG to 45 causes payload
corruption on TX.
An easy reproducer is to run ssh to connect to the machine. With
MAX_SKB_FRAGS=17 it works, with MAX_SKB_FRAGS=45 it fails. This has
been reported originally in
https://bugzilla.redhat.com/show_bug.cgi?id=2265320
The root cause of the issue is that the driver does not take into
account properly the (possibly large) shared info size when selecting
the ring layout, and will try to fit two packets inside the same 4K
page even when the 1st fraglist will trump over the 2nd head.
Address the issue by checking if 2K buffers are insufficient.

The dpaa2_switch_add_bufs() function returns the number of bufs that it
was able to add. It returns BUFS_PER_CMD (7) for complete success or a
smaller number if there are not enough pages available. However, the
error checking is looking at the total number of bufs instead of the
number which were added on this iteration. Thus the error checking
only works correctly for the first iteration through the loop and
subsequent iterations are always counted as a success.
Fix this by checking only the bufs added in the current iteration.

When working on multi-buffer packet on arch that has PAGE_SIZE >= 8192,
truesize is calculated and stored in xdp_buff::frame_sz per each
processed Rx buffer. This means that frame_sz will contain the truesize
based on last received buffer, but commit 1dc1a7e7f410 ("ice:
Centrallize Rx buffer recycling") assumed this value will be constant
for each buffer, which breaks the page recycling scheme and mess up the
way we update the page::page_offset.
To fix this, let us work on constant truesize when PAGE_SIZE >= 8192
instead of basing this on size of a packet read from Rx descriptor. This
way we can simplify the code and avoid calculating truesize per each
received frame and on top of that when using
xdp_update_skb_shared_info(), current formula for truesize update will
be valid.
This means ice_rx_frame_truesize() can be removed altogether.
Furthermore, first call to it within ice_clean_rx_irq() for 4k PAGE_SIZE
was redundant as xdp_buff::frame_sz is initialized via xdp_init_buff()
in ice_vsi_cfg_rxq(). This should have been removed at the point where
xdp_buff struct started to be a member of ice_rx_ring and it was no
longer a stack based variable.
There are two fixes tags as my understanding is that the first one
exposed us to broken truesize and page_offset handling and then second
introduced broken skb_shared_info update in ice_{construct,build}_skb().

Architectures that have PAGE_SIZE >= 8192 such as arm64 should act the
same as x86 currently, meaning reuse of a page should only take place
when no one else is busy with it.
Do two things independently of underlying PAGE_SIZE:
- store the page count under ice_rx_buf::pgcnt
- then act upon its value vs ice_rx_buf::pagecnt_bias when making the
decision regarding page reuse

If the active slave is cleared manually the xfrm state is not flushed.
This leads to xfrm add/del imbalance and adding the same state multiple
times. For example when the device cannot handle anymore states we get:
[ 1169.884811] bond0: (slave eni0np1): bond_ipsec_add_sa_all: failed to add SA
because it's filled with the same state after multiple active slave
clearings. This change also has a few nice side effects: user-space
gets a notification for the change, the old device gets its mac address
and promisc/mcast adjusted properly.

We shouldn't set real_dev to NULL because packets can be in transit and
xfrm might call xdo_dev_offload_ok() in parallel. All callbacks assume
real_dev is set.

When only the last resource is invalid, tpmi_sst_dev_add() is returing
error even if there are other valid resources before. This function
should return error when there are no valid resources.
Here tpmi_sst_dev_add() is returning "ret" variable. But this "ret"
variable contains the failure status of last call to sst_main(), which
failed for the invalid resource. But there may be other valid resources
before the last entry.
To address this, do not update "ret" variable for sst_main() return
status.
If there are no valid resources, it is already checked for by !inst
below the loop and -ENODEV is returned.
