Pull pidfd fixes from Christian Brauner:
 "Userspace tools and libraries such as strace or glibc need a cheap and
  reliable way to tell whether CLONE_PIDFD is supported. The easiest way
  is to pass an invalid fd value in the return argument, perform the
  syscall and verify the value in the return argument has been changed
  to a valid fd.

  However, if CLONE_PIDFD is specified we currently check if pidfd == 0
  and return EINVAL if not.

  The check for pidfd == 0 was originally added to enable us to abuse
  the return argument for passing additional flags along with
  CLONE_PIDFD in the future.

  However, extending legacy clone this way would be a terrible idea and
  with clone3 on the horizon and the ability to reuse CLONE_DETACHED
  with CLONE_PIDFD there's no real need for this clutch. So remove the
  pidfd == 0 check and help userspace out.

  Also, accordig to Al, anon_inode_getfd() should only be used past the
  point of no failure and ksys_close() should not be used at all since
  it is far too easy to get wrong. Al's motto being "basically, once
  it's in descriptor table, it's out of your control". So Al's patch
  switches back to what we already had in v1 of the original patchset
  and uses a anon_inode_getfile() + put_user() + fd_install() sequence
  in the success path and a fput() + put_unused_fd() in the failure
  path.

  The other two changes should be trivial"

Pull AFS fixes from David Howells:
 "The in-kernel AFS client has been undergoing testing on opendev.org on
  one of their mirror machines. They are using AFS to hold data that is
  then served via apache, and Ian Wienand had reported seeing oopses,
  spontaneous machine reboots and updates to volumes going missing. This
  patch series appears to have fixed the problem, very probably due to
  patch (2), but it's not 100% certain.

  (1) Fix the printing of the "vnode modified" warning to exclude checks
      on files for which we don't have a callback promise from the
      server (and so don't expect the server to tell us when it
      changes).

      Without this, for every file or directory for which we still have
      an in-core inode that gets changed on the server, we may get a
      message logged when we next look at it. This can happen in bulk
      if, for instance, someone does "vos release" to update a R/O
      volume from a R/W volume and a whole set of files are all changed
      together.

      We only really want to log a message if the file changed and the
      server didn't tell us about it or we failed to track the state
      internally.

  (2) Fix accidental corruption of either afs_vlserver struct objects or
      the the following memory locations (which could hold anything).
      The issue is caused by a union that points to two different
      structs in struct afs_call (to save space in the struct). The call
      cleanup code assumes that it can simply call the cleanup for one
      of those structs if not NULL - when it might be actually pointing
      to the other struct.

      This means that every Volume Location RPC op is going to corrupt
      something.

  (3) Fix an uninitialised spinlock. This isn't too bad, it just causes
      a one-off warning if lockdep is enabled when "vos release" is
      called, but the spinlock still behaves correctly.

  (4) Fix the setting of i_block in the inode. This causes du, for
      example, to produce incorrect results, but otherwise should not be
      dangerous to the kernel"

When an application is run that:
a) Sets its scheduler to be SCHED_FIFO
and
b) Opens a memory mapped AF_PACKET socket, and sends frames with the
MSG_DONTWAIT flag cleared, its possible for the application to hang
forever in the kernel.  This occurs because when waiting, the code in
tpacket_snd calls schedule, which under normal circumstances allows
other tasks to run, including ksoftirqd, which in some cases is
responsible for freeing the transmitted skb (which in AF_PACKET calls a
destructor that flips the status bit of the transmitted frame back to
available, allowing the transmitting task to complete).

However, when the calling application is SCHED_FIFO, its priority is
such that the schedule call immediately places the task back on the cpu,
preventing ksoftirqd from freeing the skb, which in turn prevents the
transmitting task from detecting that the transmission is complete.

We can fix this by converting the schedule call to a completion
mechanism.  By using a completion queue, we force the calling task, when
it detects there are no more frames to send, to schedule itself off the
cpu until such time as the last transmitted skb is freed, allowing
forward progress to be made.

Tested by myself and the reporter, with good results

Change Notes:

V1->V2:
	Enhance the sleep logic to support being interruptible and
allowing for honoring to SK_SNDTIMEO (Willem de Bruijn)

V2->V3:
	Rearrage the point at which we wait for the completion queue, to
avoid needing to check for ph/skb being null at the end of the loop.
Also move the complete call to the skb destructor to avoid needing to
modify __packet_set_status.  Also gate calling complete on
packet_read_pending returning zero to avoid multiple calls to complete.
(Willem de Bruijn)

	Move timeo computation within loop, to re-fetch the socket
timeout since we also use the timeo variable to record the return code
from the wait_for_complete call (Neil Horman)

V3->V4:
	Willem has requested that the control flow be restored to the
previous state.  Doing so lets us eliminate the need for the
po->wait_on_complete flag variable, and lets us get rid of the
packet_next_frame function, but introduces another complexity.
Specifically, but using the packet pending count, we can, if an
applications calls sendmsg multiple times with MSG_DONTWAIT set, each
set of transmitted frames, when complete, will cause
tpacket_destruct_skb to issue a complete call, for which there will
never be a wait_on_completion call.  This imbalance will lead to any
future call to wait_for_completion here to return early, when the frames
they sent may not have completed.  To correct this, we need to re-init
the completion queue on every call to tpacket_snd before we enter the
loop so as to ensure we wait properly for the frames we send in this
iteration.

	Change the timeout and interrupted gotos to out_put rather than
out_status so that we don't try to free a non-existant skb
	Clean up some extra newlines (Willem de Bruijn)

ipv6: fix neighbour resolution with raw socket

====================

The scenario is the following: the user uses a raw socket to send an ipv6
packet, destinated to a not-connected network, and specify a connected nh.
Here is the corresponding python script to reproduce this scenario:

 import socket
 IPPROTO_RAW = 255
 send_s = socket.socket(socket.AF_INET6, socket.SOCK_RAW, IPPROTO_RAW)
 # scapy
 # p = IPv6(src='fd00:100::1', dst='fd00:200::fa')/ICMPv6EchoRequest()
 # str(p)
 req = b'`\x00\x00\x00\x00\x08:@\xfd\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\xfd\x00\x02\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xfa\x80\x00\x81\xc0\x00\x00\x00\x00'
 send_s.sendto(req, ('fd00:175::2', 0, 0, 0))

fd00:175::/64 is a connected route and fd00:200::fa is not a connected
host.

With this scenario, the kernel starts by sending a NS to resolve
fd00:175::2. When it receives the NA, it flushes its queue and try to send
the initial packet. But instead of sending it, it sends another NS to
resolve fd00:200::fa, which obvioulsy fails, thus the packet is dropped. If
the user sends again the packet, it now uses the right nh (fd00:175::2).

The problem is that ip6_dst_lookup_neigh() uses the rt6i_gateway, which is
:: because the associated route is a connected route, thus it uses the dst
addr of the packet. Let's use rt6_nexthop() to choose the right nh.

it was found that vlan tagged traffic is dropped on chip.

The reason is that bridge device enables promisc mode,

So we have to corellate promisc settings with vlan configuration.

The solution is to track in a separate state variable the
need of vlan forced promisc. And also consider generic

Multicast or broadcast egress packets have rt_iif set to the oif. These
packets might be recirculated back as input and lookup to the raw
sockets may fail because they are bound to the incoming interface
(skb_iif). If rt_iif is not zero, during the lookup, inet_iif() function
returns rt_iif instead of skb_iif. Hence, the lookup fails.

get information from protocol headers encapsulated within vlan,

Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.

So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function

Caused by too many confusing indirections and casts.
id->driver_info is a pointer stored in a long.  We want the
pointer here, not the address of it.

This patch is to fix an uninit-value issue, reported by syzbot:

TLV_GET_DATA_LEN() may return a negtive int value, which will be
used as size_t (becoming a big unsigned long) passed into memchr,
cause this issue.

Similar to what it does in tipc_nl_compat_bearer_enable(), this
fix is to return -EINVAL when TLV_GET_DATA_LEN() is negtive in
tipc_nl_compat_bearer_disable(), as well as in
tipc_nl_compat_link_stat_dump() and tipc_nl_compat_link_reset_stats().

v1->v2:
  - add the missing Fixes tags per Eric's request.

This patch fixes the MAC address setup in the probe. The MAC address
retrieved using of_get_mac_address was checked for not containing an
error, but it may also be NULL which wasn't tested. Fix it by replacing
IS_ERR with IS_ERR_OR_NULL.

With commit 94850257 ("tls: Fix tls_device handling of partial records")
a new path was introduced to cleanup partial records during sk_proto_close.
This path does not handle the SW KTLS tx_list cleanup.

This is unnecessary though since the free_resources calls for both
SW and offload paths will cleanup a partial record.

The visible effect is the following warning, but this bug also causes
a page double free.

It's not okay to cast a "u32 *" to "unsigned long *" when you are
doing a for_each_set_bit() loop because that will break on big
endian systems.
