0ffd21d598 hwmon: (bt1-pvt) Wait for the completion with timeout
If the PVT sensor is suddenly powered down while a caller is waiting for
the conversion completion, the request won't be finished and the task will
hang up on this procedure until the power is back up again. Let's call the
wait_for_completion_timeout() method instead to prevent that. The cached
timeout is exactly what we need to predict for how long conversion could
normally last.

0015503e5f hwmon: (bt1-pvt) Cache current update timeout
Instead of converting the update timeout data to the milliseconds each
time on the read procedure let's preserve the currently set timeout in the
dedicated driver private data cache. The cached value will be then used in
the timeout read method and in the alarm-less data conversion to prevent
the caller task hanging up in case if the PVT sensor is suddenly powered
down.

a6db156129 hwmon: (bt1-pvt) Test sensor power supply on probe
Baikal-T1 PVT sensor has got a dedicated power supply domain (feed up by
the external GPVT/VPVT_18 pins). In case if it isn't powered up, the
registers will be accessible, but the sensor conversion just won't happen.
Due to that an attempt to read data from any PVT sensor will cause the
task hanging up.  For instance that will happen if XP11 jumper isn't
installed on the Baikal-T1-based BFK3.1 board. Let's at least test whether
the conversion work on the device probe procedure. By doing so will make
sure that the PVT sensor is powered up at least at boot time.

865e4fc013 hwmon: Add hwmon driver for Intel MAX 10 BMC
This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC
chip connects to a set of sensor chips to monitor current, voltage,
thermal and power of different components on board. The BMC firmware is
responsible for sensor data sampling and recording in shared registers.
Host driver reads the sensor data from these shared registers and
exposes them to users as hwmon interfaces.

7ed9e3d97c vhost-vdpa: fix page pinning leakage in error path
Pinned pages are not properly accounted particularly when
mapping error occurs on IOTLB update. Clean up dangling
pinned pages for the error path. As the inflight pinned
pages, specifically for memory region that strides across
multiple chunks, would need more than one free page for
book keeping and accounting. For simplicity, pin pages
for all memory in the IOVA range in one go rather than
have multiple pin_user_pages calls to make up the entire
region. This way it's easier to track and account the
pages already mapped, particularly for clean-up in the
error path.

ab5122510b vhost: Don't call log_access_ok() when using IOTLB
When the IOTLB device is enabled, the log_guest_addr that is passed by
userspace to the VHOST_SET_VRING_ADDR ioctl, and which is then written
to vq->log_addr, is a GIOVA. All writes to this address are translated
by log_user() to writes to an HVA, and then ultimately logged through
the corresponding GPAs in log_write_hva(). No logging will ever occur
with vq->log_addr in this case. It is thus wrong to pass vq->log_addr
and log_guest_addr to log_access_vq() which assumes they are actual
GPAs.

Introduce a new vq_log_used_access_ok() helper that only checks accesses
to the log for the used structure when there isn't an IOTLB device around.

0210a8db2a vhost: Don't call access_ok() when using IOTLB
When the IOTLB device is enabled, the vring addresses we get
from userspace are GIOVAs. It is thus wrong to pass them down
to access_ok() which only takes HVAs.

Access validation is done at prefetch time with IOTLB. Teach
vq_access_ok() about that by moving the (vq->iotlb) check
from vhost_vq_access_ok() to vq_access_ok(). This prevents
vhost_vring_set_addr() to fail when verifying the accesses.
No behavior change for vhost_vq_access_ok().

====================
net/sched: Add actions for MPLS L2 VPNs

This patch series adds the necessary TC actions for supporting layer 2
MPLS VPNs (VPLS).

The objective is to give the possibility to add an MPLS header right
before an skb's mac header, then to prepend this MPLS packet with a
new Ethernet header with the MAC address of the next hop.

Patch 1 implements the actions for adding and removing the external
Ethernet header.
Patch 2 adds the possibility to push an MPLS header before the mac
header.

Most of the code already exists as these operations were first
implemented in openvswitch.

Practical example, with encap on Host-A and decap on Host-B:

 Host-A# tc filter add dev ethAx ingress matchall         \
           action mpls mac_push label 20                  \
           action vlan push_eth dst_mac 02:00:00:00:00:02 \
                                src_mac 02:00:00:00:00:01 \
           action mirred egress redirect dev ethAy

 Host-B# tc filter add dev ethBx ingress protocol mpls_uc \
           flower mpls_label 20 mpls_bos 1                \

19fbcb36a3 net/sched: act_vlan: Add {POP,PUSH}_ETH actions
Implement TCA_VLAN_ACT_POP_ETH and TCA_VLAN_ACT_PUSH_ETH, to
respectively pop and push a base Ethernet header at the beginning of a
frame.

POP_ETH is just a matter of pulling ETH_HLEN bytes. VLAN tags, if any,
must be stripped before calling POP_ETH.

PUSH_ETH is restricted to skbs with no mac_header, and only the MAC
addresses can be configured. The Ethertype is automatically set from
skb->protocol. These restrictions ensure that all skb's fields remain
consistent, so that this action can't confuse other part of the
networking stack (like GSO).

Since openvswitch already had these actions, consolidate the code in
skbuff.c (like for vlan and mpls push/pop).

smatch complains about
net/iucv/af_iucv.c:624 iucv_sock_bind() error: memcpy() 'sa->siucv_user_id' too small (8 vs 9)

Which is absolutely correct - the memcpy() takes 9 bytes (sizeof(uid))
from an 8-byte field (sa->siucv_user_id).
Luckily the sockaddr_iucv struct contains more data after the
.siucv_user_id field, and we checked the size of the passed data earlier
on. So the memcpy() won't accidentally read from an invalid location.

Fix the warning by reducing the size of the uid variable to what's
actually needed, and thus reducing the amount of copied data.

388e201d41 net: stmmac: Modify configuration method of EEE timers
Ethtool manual stated that the tx-timer is the "the amount of time the
device should stay in idle mode prior to asserting its Tx LPI". The
previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW
timer duration which is not correct. Hence, this patch fixes the
"ethtool --set-eee tx-timer" to configure the EEE LPI timer.

The LPI TW Timer will be using the defined default value instead of
"ethtool --set-eee tx-timer" which follows the EEE LS timer implementation.

Changelog V2
*Not removing/modifying the eee_timer.
*EEE LPI timer can be configured through ethtool and also the eee_timer
module param.
*EEE TW Timer will be configured with default value only, not able to be
configured through ethtool or module param. This follows the implementation
of the EEE LS Timer.

186e26eb13 Merge branch 'genetlink-per-op-policy-export'
Johannes Berg says:

====================
genetlink per-op policy export

Here's a respin, now including Jakub's patch last so that it will
do the right thing from the start.

The first patch remains the same, of course; the others have mostly
some rebasing going on, except for the actual export patch (patch 4)
which is adjusted per Jakub's review comments about exporting the
policy only if it's actually used for do/dump.

To see that, the dump for "nlctrl" (i.e. the generic netlink control)
is instructive, because the ops are this:

        {
                .cmd            = CTRL_CMD_GETFAMILY,
                .validate = GENL_DONT_VALIDATE_STRICT | GENL_DONT_VALIDATE_DUMP,
                .policy         = ctrl_policy_family,
                .maxattr        = ARRAY_SIZE(ctrl_policy_family) - 1,
                .doit           = ctrl_getfamily,
                .dumpit         = ctrl_dumpfamily,
        },
        {
                .cmd            = CTRL_CMD_GETPOLICY,
                .policy         = ctrl_policy_policy,
                .maxattr        = ARRAY_SIZE(ctrl_policy_policy) - 1,
                .start          = ctrl_dumppolicy_start,
                .dumpit         = ctrl_dumppolicy,
                .done           = ctrl_dumppolicy_done,
        },

So we exercise both "don't have doit" and "GENL_DONT_VALIDATE_DUMP"
parts, and get (with the current genl patch):

$ genl ctrl policy name nlctrl
	ID: 0x10  op 3 policies: do=0
	ID: 0x10  op 10 policies: dump=1
	ID: 0x10  policy[0]:attr[1]: type=U16 range:[0,65535]
	ID: 0x10  policy[0]:attr[2]: type=NUL_STRING max len:15
	ID: 0x10  policy[1]:attr[1]: type=U16 range:[0,65535]
	ID: 0x10  policy[1]:attr[2]: type=NUL_STRING max len:15
	ID: 0x10  policy[1]:attr[10]: type=U32 range:[0,4294967295]

e992a6eda9 genetlink: allow dumping command-specific policy
Right now CTRL_CMD_GETPOLICY can only dump the family-wide
policy. Support dumping policy of a specific op.

v3:
 - rebase after per-op policy export and handle that
v2:
 - make cmd U32, just in case.
v1:
 - don't echo op in the output in a naive way, this should
   make it cleaner to extend the output format for dumping
   policies for all the commands at once in the future.

50a896cf2d genetlink: properly support per-op policy dumping
Add support for per-op policy dumping. The data is pretty much
as before, except that now the assumption that the policy with
index 0 is "the" policy no longer holds - you now need to look
at the new CTRL_ATTR_OP_POLICY attribute which is a nested attr
(indexed by op) containing attributes for do and dump policies.

When a single op is requested, the CTRL_ATTR_OP_POLICY will be
added in the same way, since do and dump policies may differ.

v2:
 - conditionally advertise per-command policies only if there
   actually is a policy being used for the do/dump and it's
   present at all

 - squash the first patch to not flip-flop on the prototype
   [Jakub]
 - merge netlink_policy_dump_get_policy_idx() with the old
   get_policy_idx() we already had
 - rebase without Jakub's patch to have per-op dump
