'psock_fanout' has been failing since commit 4d7b9dc1 ("tools:
psock_lib: harden socket filter used by psock tests").  That commit
changed the CBPF filter to examine the full ethernet frame, and was
tested on 'psock_tpacket' which uses SOCK_RAW.  But 'psock_fanout' was
also using this same CBPF in two places, for filtering and fanout, on a
SOCK_DGRAM socket.

Change 'psock_fanout' to use SOCK_RAW so that the CBPF program used with
SO_ATTACH_FILTER can examine the entire frame.  Create a new CBPF
program for use with PACKET_FANOUT_DATA which ignores the header, as it
cannot see the ethernet header.

Tested: Ran tools/testing/selftests/net/psock_{fanout,tpacket} 10 times,
and they all passed.

AP/AP_VLAN modes don't accept any real 802.11 multicast data
frames, but since they do need to accept broadcast management
frames the same is currently permitted for data frames. This
opens a security problem because such frames would be decrypted
with the GTK, and could even contain unicast L3 frames.

Since the spec says that ToDS frames must always have the BSSID
as the RA (addr1), reject any other data frames.

The problem was originally reported in "Predicting, Decrypting,
and Abusing WPA2/802.11 Group Keys" at usenix
https://www.usenix.org/conference/usenixsecurity16/technical-sessions/presentation/vanhoef
and brought to my attention by Jouni.

The DMA API debugging (when enabled) causes:

WARNING: CPU: 0 PID: 1445 at lib/dma-debug.c:519 add_dma_entry+0xe0/0x12c
DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d

to be  printed after repeated initialization of the Ether device, e.g.
suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped
using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are
never unmapped. Resolve this problem by unmapping the buffers when freeing
the descriptor  rings;  in order  to do it right, we'd have to add an extra
parameter to sh_eth_txfree() (we rename this function to sh_eth_tx_free(),
while at it).

When function tracer has a pid filter, it adds a probe to sched_switch
to track if current task can be ignored.  The probe checks the
ftrace_ignore_pid from current tr to filter tasks.  But it misses to
delete the probe when removing an instance so that it can cause a crash
due to the invalid tr pointer (use-after-free).

This is easily reproducible with the following:

  # cd /sys/kernel/debug/tracing
  # mkdir instances/buggy
  # echo $$ > instances/buggy/set_ftrace_pid
  # rmdir instances/buggy

Two BPF fixes

The set fixes cb_access and xdp_adjust_head bits in struct bpf_prog,
that are used for requirement checks on the program rather than f.e.
heuristics. Thus, for tail calls, we cannot make any assumptions and
are forced to set them.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 17bedab2 ("bpf: xdp: Allow head adjustment in XDP prog")
added the xdp_adjust_head bit to the BPF prog in order to tell drivers
that the program that is to be attached requires support for the XDP
bpf_xdp_adjust_head() helper such that drivers not supporting this
helper can reject the program. There are also drivers that do support
the helper, but need to check for xdp_adjust_head bit in order to move
packet metadata prepended by the firmware away for making headroom.

For these cases, the current check for xdp_adjust_head bit is insufficient
since there can be cases where the program itself does not use the
bpf_xdp_adjust_head() helper, but tail calls into another program that
uses bpf_xdp_adjust_head(). As such, the xdp_adjust_head bit is still
set to 0. Since the first program has no control over which program it
calls into, we need to assume that bpf_xdp_adjust_head() helper is used
upon tail calls. Thus, for the very same reasons in cb_access, set the
xdp_adjust_head bit to 1 when the main program uses tail calls.

Commit ff936a04 ("bpf: fix cb access in socket filter programs")
added a fix for socket filter programs such that in i) AF_PACKET the
20 bytes of skb->cb[] area gets zeroed before use in order to not leak
data, and ii) socket filter programs attached to TCP/UDP sockets need
to save/restore these 20 bytes since they are also used by protocol
layers at that time.

The problem is that bpf_prog_run_save_cb() and bpf_prog_run_clear_cb()
only look at the actual attached program to determine whether to zero
or save/restore the skb->cb[] parts. There can be cases where the
actual attached program does not access the skb->cb[], but the program
tail calls into another program which does access this area. In such
a case, the zero or save/restore is currently not performed.

Since the programs we tail call into are unknown at verification time
and can dynamically change, we need to assume that whenever the attached
program performs a tail call, that later programs could access the
skb->cb[], and therefore we need to always set cb_access to 1.

mediatek: Fix crash caused by reporting inconsistent skb->len to BQL

Changes since v1:
- fix inconsistent enumeration which easily causes the potential bug

The series fixes kernel BUG caused by inconsistent SKB length reported
into BQL. The reason for inconsistent length comes from hardware BUG which
results in different port number carried on the TXD within the lifecycle of
SKB. So patch 2) is proposed for use a software way to track which port
the SKB involving instead of hardware way. And patch 1) is given for another
issue I found which causes TXD and SKB inconsistency that is not expected
in the initial logic, so it is also being corrected it in the series.

The log for the kernel BUG caused by the issue is posted as below.

Syzkaller reported a use-after-free in ip_recv_error at line

    info->ipi_ifindex = skb->dev->ifindex;

This function is called on dequeue from the error queue, at which
point the device pointer may no longer be valid.

Save ifindex on enqueue in __skb_complete_tx_timestamp, when the
pointer is valid or NULL. Store it in temporary storage skb->cb.

It is safe to reference skb->dev here, as called from device drivers
or dev_queue_xmit. The exception is when called from tcp_ack_tstamp;
in that case it is NULL and ifindex is set to 0 (invalid).

Do not return a pktinfo cmsg if ifindex is 0. This maintains the
current behavior of not returning a cmsg if skb->dev was NULL.

On dequeue, the ipv4 path will cast from sock_exterr_skb to
in_pktinfo. Both have ifindex as their first element, so no explicit
conversion is needed. This is by design, introduced in commit
0b922b7a ("net: original ingress device index in PKTINFO"). For
ipv6 ip6_datagram_support_cmsg converts to in6_pktinfo.

or the cpu topology. If that is higher than EFX_MAX_RX_QUEUES the
driver can corrupt state.

Pull ARM SoC fixes from Olof Johansson:
 "Again, a batch that's been sitting a couple of weeks, mostly because
  I anticipated a bit more material but it didn't show up -- which is
  good.

  These are all your garden variety fixes for ARM platforms.

  The most visible issue fixed here is probably the SMP reset issue on
  OMAP, the rest are minor stuff"

  The original issue is one that we have lived with for decades, so

Pull ftrace fix from Steven Rostedt:
 "While rewriting the function probe code, I stumbled over a long
  standing bug. This bug has been there sinc function tracing was added
  way back when. But my new development depends on this bug being fixed,
  and it should be fixed regardless as it causes ftrace to disable
  itself when triggered, and a reboot is required to enable it again.

  The bug is that the function probe does not disable itself properly if
  there's another probe of its type still enabled. For example:

     # cd /sys/kernel/debug/tracing
     # echo schedule:traceoff > set_ftrace_filter
     # echo do_IRQ:traceoff > set_ftrace_filter
     # echo \!do_IRQ:traceoff > /debug/tracing/set_ftrace_filter
     # echo do_IRQ:traceoff > set_ftrace_filter

  The above registers two traceoff probes (one for schedule and one for
  do_IRQ, and then removes do_IRQ.

  But since there still exists one for schedule, it is not done
  properly. When adding do_IRQ back, the breakage in the accounting is
  noticed by the ftrace self tests, and it causes a warning and disables
  ftrace"

read by get_user() was lost on a 32-bit kernel.

Pull nvdimm fixes from Dan Williams:
 "A small crop of lockdep, sleeping while atomic, and other fixes /
  band-aids in advance of the full-blown reworks targeting the next
  merge window. The largest change here is "libnvdimm: fix blk free
  space accounting" which deletes a pile of buggy code that better
  testing would have caught before merging. The next change that is
  borderline too big for a late rc is switching the device-dax locking
  from rcu to srcu, I couldn't think of a smaller way to make that fix.

  The __copy_user_nocache fix will have a full replacement in 4.12 to
  move those pmem special case considerations into the pmem driver. The
  "libnvdimm: band aid btt vs clear poison locking" commit admits that
  our error clearing support for btt went in broken, so we just disable
  it in 4.11 and -stable. A replacement / full fix is in the pipeline
  for 4.12

  Some of these would have been caught earlier had DEBUG_ATOMIC_SLEEP
  been enabled on my development station. I wonder if we should have:

      config DEBUG_ATOMIC_SLEEP
        default PROVE_LOCKING

  ...since I mistakenly thought I got both with PROVE_LOCKING=y.

  These have received a build success notification from the 0day robot,
  and some have appeared in a -next release with no reported issues"

  in case).

  The next is the sd capacity fix which means all non 512 byte sector
  drives greater than 2TB fail to be correctly sized.
