HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large

The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains
a typo which defines an incorrect logical maximum Y value. This causes
a small portion of the bottom of the tablet to become unusable (both
because the area is below the "bottom" of the tablet and because
'wacom_wac_event' ignores out-of-range values). It also results in a
skewed aspect ratio.

To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites
the data with the correct value.

HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation

Current ISH driver only registers suspend/resume PM callbacks which don't
support hibernation (suspend to disk). Basically after hiberation, the ISH
can't resume properly and user may not see sensor events (for example: screen
rotation may not work).

User will not see a crash or panic or anything except the following message
in log:

hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device

So this patch adds support for S4/hiberbation to ISH by using the
SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
and resume functions will now be used for both suspend to RAM and hibernation.

If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
and resume related functions won't be used, so mark them as __maybe_unused to
clarify that this is the intended behavior, and remove #ifdefs for power
management.

HID: steam: use hid_device.driver_data instead of hid_set_drvdata()

When creating the low-level hidraw device, the reference to steam_device
was stored using hid_set_drvdata(). But this value is not guaranteed to
be kept when set before calling probe. If this pointer is reset, it
crashes when opening the emulated hidraw device.

It looks like hid_set_drvdata() is for users "avobe" this hid_device,
while hid_device.driver_data it for users "below" this one.

In this case, we are creating a virtual hidraw device, so we must use
hid_device.driver_data.

proc: fix missing final NUL in get_mm_cmdline() rewrite

The rewrite of the cmdline fetching missed the fact that we used to also
return the final terminating NUL character of the last argument. I
hadn't noticed, and none of the tools I tested cared, but something
obviously must care, because Michal Kubecek noticed the change in
behavior.

Tweak the "find the end" logic to actually include the NUL character,
and once past the eend of argv, always start the strnlen() at the
expected (original) argument end.

This whole "allow people to rewrite their arguments in place" is a nasty
hack and requires that odd slop handling at the end of the argv array,
but it's our traditional model, so we continue to support it.

net: stmmac: socfpga: add additional ocp reset line for Stratix10

The Stratix10 platform has an additional reset line, OCP(Open Core Protocol),

Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build
dwmac-socfpga.

Also, remove the redundant check for the reset controller pointer. The
reset driver already checks for the pointer and returns 0 if the pointer
is NULL.

net: sungem: fix rx checksum support

After commit 88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE
are friends"), sungem owners reported the infamous "eth0: hw csum failure"
message.

CHECKSUM_COMPLETE has in fact never worked for this driver, but this
was masked by the fact that upper stacks had to strip the FCS, and
therefore skb->ip_summed was set back to CHECKSUM_NONE before
my recent change.

Driver configures a number of bytes to skip when the chip computes
the checksum, and for some reason only half of the Ethernet header
was skipped.

Then a second problem is that we should strip the FCS by default,
unless the driver is updated to eventually support NETIF_F_RXFCS in
the future.

Finally, a driver should check if NETIF_F_RXCSUM feature is enabled
or not, so that the admin can turn off rx checksum if wanted.

Many thanks to Andreas Schwab and Mathieu Malaterre for their
help in debugging this issue.

net/sched: act_ife: fix recursive lock and idr leak

a recursive lock warning [1] can be observed with the following script,

# $TC actions add action ife encode allow prio pass index 42
IFE type 0xED3E
# $TC actions replace action ife encode allow tcindex pass index 42

in case the kernel was unable to run the last command (e.g. because of
the impossibility to load 'act_meta_skbtcindex'). For a similar reason,
the kernel can leak idr in the error path of tcf_ife_init(), because
tcf_idr_release() is not called after successful idr reservation:

# $TC actions add action ife encode allow tcindex index 47
IFE type 0xED3E
RTNETLINK answers: No such file or directory
We have an error talking to the kernel
# $TC actions add action ife encode allow tcindex index 47
IFE type 0xED3E
RTNETLINK answers: No space left on device
We have an error talking to the kernel
# $TC actions add action ife encode use mark 7 type 0xfefe pass index 47
IFE type 0xFEFE
RTNETLINK answers: No space left on device
We have an error talking to the kernel

Since tcfa_lock is already taken when the action is being edited, a call
to tcf_idr_release() wrongly makes tcf_idr_cleanup() take the same lock
again. On the other hand, tcf_idr_release() needs to be called in the
error path of tcf_ife_init(), to undo the last tcf_idr_create() invocation.
Fix both problems in tcf_ife_init().
Since the cleanup() routine can now be called when ife->params is NULL,
also add a NULL pointer check to avoid calling kfree_rcu(NULL, rcu).

net: ethernet: fix suspend/resume in davinci_emac

This patch reverts commit 3243ff2a05ec ("net: ethernet: davinci_emac:
Deduplicate bus_find_device() by name matching") and adds a comment
which should stop anyone from reintroducing the same "fix" in the future.

We can't use bus_find_device_by_name() here because the device name is
not guaranteed to be 'davinci_mdio'. On some systems it can be
'davinci_mdio.0' so we need to use strncmp() against the first part of
the string to correctly match it.

net/tcp: Fix socket lookups with SO_BINDTODEVICE

Similar to 69678bcd4d2d ("udp: fix SO_BINDTODEVICE"), TCP socket lookups
need to fail if dev_match is not true. Currently, a packet to a given port
can match a socket bound to device when it should not. In the VRF case,
this causes the lookup to hit a VRF socket and not a global socket
resulting in a response trying to go through the VRF when it should not.

bpf, xdp, i40e: fix i40e_build_skb skb reserve and truesize

Using skb_reserve(skb, I40E_SKB_PAD + (xdp->data - xdp->data_hard_start))
is clearly wrong since I40E_SKB_PAD already points to the offset where
the original xdp->data was sitting since xdp->data_hard_start is defined
as xdp->data - i40e_rx_offset(rx_ring) where latter offsets to I40E_SKB_PAD
when build skb is used.

However, also before cc5b114dcf98 ("bpf, i40e: add meta data support")
this seems broken since bpf_xdp_adjust_head() helper could have been used
to alter headroom and enlarge / shrink the frame and with that the assumption
that the xdp->data remains unchanged does not hold and would push a bogus
packet to upper stack.

ixgbe got this right in 924708081629 ("ixgbe: add XDP support for pass and
drop actions"). In any case, fix it by removing the I40E_SKB_PAD from both
skb_reserve() and truesize calculation.

sunrpc: Prevent duplicate XID allocation

Krzysztof Kozlowski <krzk@kernel.org> reports that a heavy NFSv4
WRITE workload against a slow NFS server causes his Raspberry Pi
clients to stall. Krzysztof bisected it to commit 37ac86c3a76c
("SUNRPC: Initialize rpc_rqst outside of xprt->reserve_lock") .

I was able to reproduce similar behavior and it appears that rarely
the RPC client layer is re-allocating an XID for an RPC that it has
already partially sent. This results in the client ignoring the
subsequent reply, which carries the original XID.

For various reasons, checking !req->rq_xmit_bytes_sent in
xprt_prepare_transmit is not a 100% reliable mechanism for
determining when a fresh XID is needed.

Trond's preference is to allocate the XID at the time each rpc_rqst
slot is initialized.

This patch should also address a gcc 4.1.2 complaint reported by
Geert Uytterhoeven <geert@linux-m68k.org>.

PM / OPP: Update voltage in case freq == old_freq

This commit fixes a rare but possible case when the clk rate is updated
without update of the regulator voltage.

At boot up, CPUfreq checks if the system is running at the right freq. This
is a sanity check in case a bootloader set clk rate that is outside of freq
table present with cpufreq core. In such cases system can be unstable so
better to change it to a freq that is preset in freq-table.

The CPUfreq takes next freq that is >= policy->cur and this is our
target_freq that needs to be set now.

dev_pm_opp_set_rate(dev, target_freq) checks the target_freq and the
old_freq (a current rate). If these are equal it returns early. If not,
it searches for OPP (old_opp) that fits best to old_freq (not listed in
the table) and updates old_freq (!).

Here, we can end up with old_freq = old_opp.rate = target_freq, which
is not handled in _generic_set_opp_regulator(). It's supposed to update
voltage only when freq > old_freq  || freq > old_freq.

if (freq > old_freq) {
ret = _set_opp_voltage(dev, reg, new_supply);
[...]
if (freq < old_freq) {
ret = _set_opp_voltage(dev, reg, new_supply);
if (ret)

It results in, no voltage update while clk rate is updated.

Example:
freq-table = {
1000MHz   1.15V
666MHZ   1.10V
333MHz   1.05V
}
boot-up-freq        = 800MHz   # not listed in freq-table
freq = target_freq  = 1GHz
old_freq            = 800Mhz
old_opp = _find_freq_ceil(opp_table, &old_freq);  #(old_freq is modified!)
old_freq            = 1GHz

cpufreq: intel_pstate: Fix scaling max/min limits with Turbo 3.0

When scaling max/min settings are changed, internally they are converted
to a ratio using the max turbo 1 core turbo frequency. This works fine
when 1 core max is same irrespective of the core. But under Turbo 3.0,
this will not be the case. For example:
Core 0: max turbo pstate: 43 (4.3GHz)
Core 1: max turbo pstate: 45 (4.5GHz)
In this case 1 core turbo ratio will be maximum of all, so it will be
45 (4.5GHz). Suppose scaling max is set to 4GHz (ratio 40) for all cores
,then on core one it will be
= max_state * policy->max / max_freq;
= 43 * (4000000/4500000) = 38 (3.8GHz)
= 38
which is 200MHz less than the desired.
On core2, it will be correctly set to ratio 40 (4GHz). Same holds true
for scaling min frequency limit. So this requires usage of correct turbo
max frequency for core one, which in this case is 4.3GHz. So we need to
adjust per CPU cpu->pstate.turbo_freq using the maximum HWP ratio of that
core.

This change uses the HWP capability of a core to adjust max turbo
frequency. But since Broadwell HWP doesn't use ratios in the HWP
capabilities, we have to use legacy max 1 core turbo ratio. This is not
a problem as the HWP capabilities don't differ among cores in Broadwell.
We need to check for non Broadwell CPU model for applying this change,
though.

pinctrl: devicetree: Fix pctldev pointer overwrite

Commit b89405b6102f ("pinctrl: devicetree: Fix dt_to_map_one_config
handling of hogs") causes the pinctrl hog pins to not get initialized
on i.MX platforms leaving them with the IOMUX settings untouched.

This causes several regressions on i.MX such as:

- OV5640 camera driver can not be probed anymore on imx6qdl-sabresd
because the camera clock pin is in a pinctrl_hog group and since
its pinctrl initialization is skipped, the camera clock is kept
in GPIO functionality instead of CLK_CKO function.

- Audio stopped working on imx6qdl-wandboard and imx53-qsb for
the same reason.

Richard Fitzgerald explains the problem:

"I see the bug. If the hog node isn't a 1st level child of the pinctrl
parent node it will go around the for(;;) loop again but on the first
pass I overwrite pctldev with the result of
get_pinctrl_dev_from_of_node() so it doesn't point to the pinctrl driver
any more."

Fix the issue by stashing the original pctldev so it doesn't
get overwritten.

atm: Preserve value of skb->truesize when accounting to vcc

ATM accounts for in-flight TX packets in sk_wmem_alloc of the VCC on
which they are to be sent. But it doesn't take ownership of those
packets from the sock (if any) which originally owned them. They should
remain owned by their actual sender until they've left the box.

There's a hack in pskb_expand_head() to avoid adjusting skb->truesize
for certain skbs, precisely to avoid messing up sk_wmem_alloc
accounting. Ideally that hack would cover the ATM use case too, but it
doesn't — skbs which aren't owned by any sock, for example PPP control
frames, still get their truesize adjusted when the low-level ATM driver
adds headroom.

This has always been an issue, it seems. The truesize of a packet
increases, and sk_wmem_alloc on the VCC goes negative. But this wasn't
for normal traffic, only for control frames. So I think we just got away
with it, and we probably needed to send 2GiB of LCP echo frames before
the misaccounting would ever have caused a problem and caused
atm_may_send() to start refusing packets.

Commit 14afee4b609 ("net: convert sock.sk_wmem_alloc from atomic_t to
refcount_t") did exactly what it was intended to do, and turned this
mostly-theoretical problem into a real one, causing PPPoATM to fail
immediately as sk_wmem_alloc underflows and atm_may_send() *immediately*
starts refusing to allow new packets.

The least intrusive solution to this problem is to stash the value of
skb->truesize that was accounted to the VCC, in a new member of the
ATM_SKB(skb) structure. Then in atm_pop_raw() subtract precisely that
value instead of the then-current value of skb->truesize.

   code missed the related update, from Toshiaki.

2) Fix a freeze when BPF progs are loaded that include BPF to BPF
   calls when JIT is enabled where we would later bail out via error
   path w/o dropping kallsyms, and another one to silence syzkaller
   splats from locking prog read-only, from Daniel.

3) Fix a bug in test_offloads.py BPF selftest which must not assume
   that the underlying system have no BPF progs loaded prior to test,
   and one in bpftool to fix accuracy of program load time, from Jakub.

4) Fix a bug in bpftool's probe for availability of the bpf(2)
   BPF_TASK_FD_QUERY subcommand, from Yonghong.

5) Fix a regression in AF_XDP's XDP_SKB receive path where queue

cifs: Fix invalid check in __cifs_calc_signature()

The following check would never evaluate to true:
> if (i == 0 && iov[0].iov_len <= 4)

Because 'i' always starts at 1.

This patch fixes it and also move the header checks outside the for loop
- which makes more sense.

cifs: Use correct packet length in SMB2_TRANSFORM header

In smb3_init_transform_rq(), 'orig_len' was only counting the request
length, but forgot to count any data pages in the request.

Writing or creating files with the 'seal' mount option was broken.

In addition, do some code refactoring by exporting smb2_rqst_len() to
calculate the appropriate packet size and avoid duplicating the same
calculation all over the code.

The start of the io vector is either the rfc1002 length (4 bytes) or a
SMB2 header which is always > 4. Use this fact to check and skip the
rfc1002 length if requested.
