Currently the loop checks for non-zero count of sensors for each type
of sensors which is completely wrong. It also results in aborting the
registration of sensors if one or more types of sensors are completely
not supported by the platform SCMI firmware.
This patch fixes the issue by continue to loop and skiping sensor types
that are not present.

Daniel Borkmann says:
====================
pull-request: bpf 2018-04-21
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a deadlock between mm->mmap_sem and bpf_event_mutex when
one task is detaching a BPF prog via perf_event_detach_bpf_prog()
and another one dumping through bpf_prog_array_copy_info(). For
the latter we move the copy_to_user() out of the bpf_event_mutex
lock to fix it, from Yonghong.
2) Fix test_sock and test_sock_addr.sh failures. The former was
hitting rlimit issues and the latter required ping to specify
the address family, from Yonghong.
3) Remove a dead check in sockmap's sock_map_alloc(), from Jann.
4) Add generated files to BPF kselftests gitignore that were previously
missed, from Anders.

Avoid using value stored in the login response buffer when
cleaning TX and RX buffer pools since these could be inconsistent
depending on the device state. Instead use the field in the driver's
private data that tracks the number of active pools.

net: sched: ife: malformed ife packet fixes
As promised at netdev 2.2 tc workshop I am working on adding scapy support for
tdc testing. It is still work in progress. I will submit the patches to tdc
later (they are not in good shape yet). The good news is I have been able to
find bugs which normal packet testing would not be able to find.
With fuzzy testing I was able to craft certain malformed packets that IFE
action was not able to deal with. This patch set fixes those bugs.
changes since v4:
- use pskb_may_pull before pointer assign
changes since v3:
- use pskb_may_pull
changes since v2:
- remove inline from __ife_tlv_meta_valid
- add const to cast to meta_tlvhdr
- add acked and reviewed tags

struct sock's sk_rcvtimeo is initialized to
LONG_MAX/MAX_SCHEDULE_TIMEOUT in sock_init_data. Calling
mod_delayed_work with a timeout of LONG_MAX causes spurious execution of
the work function. timer->expires is set equal to jiffies + LONG_MAX.
When timer_base->clk falls behind the current value of jiffies,
the delta between timer_base->clk and jiffies + LONG_MAX causes the
expiration to be in the past. Returning early from strp_start_timer if
timeo == LONG_MAX solves this problem.
Found while testing net/tls_sw recv path.

In case of seg6 in encap mode, seg6_do_srh_encap() calls set_tun_src()
in order to set the src addr of outer IPv6 header.
The net_device is required for set_tun_src(). However calling ip6_dst_idev()
on dst_entry in case of IPv4 traffic results on the following bug.
Using just dst->dev should fix this BUG.

The connection timers of an llc sock could be still flying
after we delete them in llc_sk_free(), and even possibly
after we free the sock. We could just wait synchronously
here in case of troubles.
Note, I leave other call paths as they are, since they may
not have to wait, at least we can change them to synchronously
when needed.
Also, move the code to net/llc/llc_conn.c, which is apparently
a better place.

Commit 0e0c3fee3a59 ("l2tp: hold reference on tunnels printed in pppol2tp proc file")
assumed that if pppol2tp_seq_stop() was called with non-NULL private
data (the 'v' pointer), then pppol2tp_seq_start() would not be called
again. It turns out that this isn't guaranteed, and overflowing the
seq_file's buffer in pppol2tp_seq_show() is a way to get into this
situation.
Therefore, pppol2tp_seq_stop() needs to reset pd->tunnel, so that
pppol2tp_seq_start() won't drop a reference again if it gets called.
We also have to clear pd->session, because the rest of the code expects
a non-NULL tunnel when pd->session is set.
The l2tp_debugfs module has the same issue. Fix it in the same way.

s390/qeth: fixes 2018-04-19

For z/VM NICs, qeth needs to consider which of the three CCW devices in
an MPC group it uses for requesting a managed MAC address.
On the Base device, the hypervisor returns a default MAC which is
pre-assigned when creating the NIC (this MAC is also returned by the
READ MAC primitive). Querying any other device results in the allocation
of an additional MAC address.
For consistency with READ MAC and to avoid using up more addresses than
necessary, it is preferable to use the NIC's default MAC. So switch the
the diag26c over to using a NIC's Read device, which should always be
identical to the Base device.

Submitting a cmd IO request (usually on the WRITE device, but for IDX
also on the READ device) is currently done with ccw_device_start()
and a manual timeout in the caller.
On timeout, the caller cleans up the related resources (eg. IO buffer).
But 1) the IO might still be active and utilize those resources, and
2) when the IO completes, qeth_irq() will attempt to clean up the
same resources again.
Instead of introducing additional resource locking, switch to
ccw_device_start_timeout() to ensure IO termination after timeout, and
let the IRQ handler alone deal with cleaning up after a request.
This also removes a stray write->irq_pending reset from
clear_ipacmd_list(). The routine doesn't terminate any pending IO on
the WRITE device, so this should be handled properly via IO timeout
in the IRQ handler.

When changing the MAC address on a L2 qeth device, current code first
unregisters the old address, then registers the new one.
If HW rejects the new address (or the IO fails), the device ends up with
no operable address at all.
Re-order the code flow so that the old address only gets dropped if the
new address was registered successfully. While at it, add logic to catch
some corner-cases.

For control IO, qeth currently tracks the index of the buffer that it
expects to complete the next IO on each qeth_channel. If the channel
presents an IRQ while this buffer has not yet completed, no completion
processing for _any_ completed buffer takes place.
So if the 'next buffer' is skipped for any sort of reason* (eg. when it
is released due to error conditions, before the IO is started), the
buffer obviously won't switch to PROCESSED until it is eventually
allocated for a _different_ IO and completes.
Until this happens, all completion processing on that channel stalls
and pending requests possibly time out.
As a fix, remove the whole 'next buffer' logic and simply process any
IO buffer right when it completes. A channel will never have more than
one IO pending, so there's no risk of processing out-of-sequence.
*Note: currently just one location in the code really handles this problem,
by advancing the 'next' index manually.

Make sure to check both return code fields before(!) processing the
command response. Otherwise we risk operating on invalid data.

Commit e7bfb3fdbde3 ("mtd: Stop updating erase_info->state and calling
mtd_erase_callback()") removed the einfo->state field and the
MTD_ERASE_XXX macros. At the same time, the generic NAND layer was added
and made sure to update the erase info state.
It did not result in a build failure after merging the nand/for-4.17
branch in mtd/next because the generic NAND layer is not selected yet.
Let's fix that before a config option starts selecting MTD_NAND_CORE.

Commit 68a0db1d7da2 reworked the baud rate selection, but also added
a (not so) subtle change in the way the local flags (c_lflag in the
termios structure) are handled, forcing the new flags to always be the
same as the old ones.
The reason for that particular change is both obscure and undocumented.
It also completely breaks userspace. Something as trivial as getty is
unusable:
<example>
Debian GNU/Linux 9 sy-borg ttyMV0
sy-borg login: root
root
[timeout]
Debian GNU/Linux 9 sy-borg ttyMV0
</example>
which is quite obvious in retrospect: getty cannot get in control of
the echo mode, is stuck in canonical mode, and times out without ever
seeing anything valid. It also begs the question of how this change was
ever tested.
The fix is pretty obvious: stop messing with c_lflag, and the world
will be a happier place.

At least on droid 4 with control channel in ADM mode, there is no response
to Modem Status Command (MSC). Currently gsmtty_modem_update() expects to
have data in dlci->modem_rx unless debug & 2 is set. This means that on
droid 4, things only work if debug & 2 is set.
Let's fix the issue by ignoring empty dlci->modem_rx for ADM mode. In
the AMD mode, CMD_MSC will never respond and gsm_process_modem() won't
get called to set dlci->modem_rx.
And according to ts_127010v140000p.pdf, MSC is only relevant if basic
option is chosen, so let's test for that too.

Commit ea3d8465ab9b ("tty: n_gsm: Allow ADM response in addition to UA for
control dlci") added support for DLCI to stay in Asynchronous Disconnected
Mode (ADM). But we still get long delays waiting for commands to other
DLCI to complete:
--> 5) C: SABM(P)
Q> 0) C: UIH(F)
Q> 0) C: UIH(F)
Q> 0) C: UIH(F)
...
This happens because gsm_control_send() sets cretries timer to T2 that is
by default set to 34. This will cause resend for T2 times for the control
frame. In ADM mode, we will never get a response so the control frame, so
retries are just delaying all the commands.
Let's fix the issue by setting DLCI_MODE_ADM flag after detecting the ADM
mode for the control DLCI. Then we can use that in gsm_control_send() to
set retries to 1. This means the control frame will be sent once allowing
the other end at an opportunity to switch from ADM to ABM mode.
Note that retries will be decremented in gsm_control_retransmit() so
we don't want to set it to 0 here.

If the generic PHY support is disabled the stub of devm_of_phy_get_by_index
returns ENOSYS. This corner case isn't handled properly by
usb_phy_roothub_add_phy and at least breaks USB support on Raspberry Pi
(bcm2835_defconfig):
dwc2 20980000.usb: dwc2_hcd_init() FAILED, returning -38
dwc2: probe of 20980000.usb failed with error -38
Let usb_phy_roothub_alloc() return in case CONFIG_GENERIC_PHY is
disabled to fix this issue (compilers might even be smart enough to
optimize away most of the code within usb_phy_roothub_alloc and
usb_phy_roothub_add_phy if CONFIG_GENERIC_PHY is disabled). All
existing usb_phy_roothub_* functions are already NULL-safe, so no
special handling is required there.

If the USB controller can wake up the system (which is the case for
example with the Mediatek USB3 IP) then we must not call phy_exit during
suspend to ensure that the USB controller doesn't have to re-enumerate
the devices during resume.
However, if the USB controller cannot wake up the system (which is the
case for example on various TI platforms using a dwc3 controller) then
we must call phy_exit during suspend. Otherwise the PHY driver keeps the
clocks enabled, which prevents the system from reaching the lowest power
levels in the suspend state.
Solve this by introducing two new functions in the PHY wrapper which are
dedicated to the suspend and resume handling.
If the controller can wake up the system the new usb_phy_roothub_suspend
function will simply call usb_phy_roothub_power_off. However, if wake up
is not supported by the controller it will also call
usb_phy_roothub_exit.
The also new usb_phy_roothub_resume function takes care of calling
usb_phy_roothub_init (if the controller can't wake up the system) in
addition to usb_phy_roothub_power_on.

Before this patch usb_phy_roothub_init served two purposes (from a
caller's point of view - like hcd.c):
- parsing the PHYs and allocating the list entries
- calling phy_init on each list entry
While this worked so far it has one disadvantage: if we need to call
phy_init for each PHY instance then the existing code cannot be re-used.
Solve this by splitting off usb_phy_roothub_alloc which only parses the
PHYs and allocates the list entries.
usb_phy_roothub_init then gets a struct usb_phy_roothub and only calls
phy_init on each PHY instance (along with the corresponding cleanup if
that failed somewhere).
This is a preparation step for adding proper suspend support for some
hardware that requires phy_exit to be called during suspend and phy_init
to be called during resume.

usb_phy_roothub_exit() should return the error code from the phy_exit()
call if exiting the PHY failed.
However, since a wrong variable is used usb_phy_roothub_exit() currently
always returns 0, even if one of the phy_exit calls returned an error.
Clang also reports this bug:

On some boards, under heavy load, the EC firmware is
unable to complete commands even in one second. Increasing
the command completion timeout value to five seconds.

This reverts commit b07c12517f2aed0add8ce18146bb426b14099392
It is incomplete and causes hangs on devices when shutting down. It
needs a much more "complete" fix in order to work properly. As that fix
has not been merged, revert this patch for now before it causes any more
problems.

Using reStructuredText literal-block element with ascii-art.
That prevents the ascii art from being processed as
reStructuredText.

There is the following build error with CONFIG_TYPEC_UCSI=m, CONFIG_FTRACE=y
and CONFIG_TRACING=n:
ERROR: "__tracepoint_ucsi_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_register_port" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_notify" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_reset_ppm" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_run_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_ack" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_connector_change" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
This compination is quite hard to create because CONFIG_TRACING gets selected
only in rare cases without CONFIG_FTRACE.
The build failure is caused by conditionally compiling trace.c depending on
the wrong option CONFIG_FTRACE. Change this to depend on CONFIG_TRACING like
other users of tracepoints do.

Fix it to not print kernel pointer address. Remove the conditional
and debug message as it isn't very useful.
