ASoC: Fixes for v4.2

A lot of small fixes here, a few to the core:

 - Fix for binding DAPM stream widgets on devices with prefixes assigned
   to them
 - Minor fixes for the newly added topology interfaces
 - Locking and memory leak fixes for DAPM
 - Driver specific fixes

c387995695 ASoC: topology: add private data to manifest
The topology file manifest should include a private data field. This
allows vendors to specify vendor data in the manifest, like
timestamps, hashes, additional information for removing platform
configuration out of drivers and making these configurable per platform

3b8a684bd6 drm/atomic-helper: Add an atomice best_encoder callback
With legacy helpers all the routing was already set up when calling
best_encoder and so could be inspected. But with atomic it's staged,
hence we need a new atomic compliant callback for drivers which need
to inspect the requested state and can't just decided the best encoder
statically.

This is needed to fix up i915 dp mst where we need to pick the right
encoder depending upon the requested CRTC for the connector.

28e6b67f0b net: sched: fix refcount imbalance in actions
Since commit 55334a5db5 ("net_sched: act: refuse to remove bound action
outside"), we end up with a wrong reference count for a tc action.

Test case 1:

  FOO="1,6 0 0 4294967295,"
  BAR="1,6 0 0 4294967294,"
  tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 \
     action bpf bytecode "$FOO"
  tc actions show action bpf
    action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe
    index 1 ref 1 bind 1
  tc actions replace action bpf bytecode "$BAR" index 1
  tc actions show action bpf
    action order 0: bpf bytecode '1,6 0 0 4294967294' default-action pipe
    index 1 ref 2 bind 1
  tc actions replace action bpf bytecode "$FOO" index 1
  tc actions show action bpf
    action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe
    index 1 ref 3 bind 1

Test case 2:

  FOO="1,6 0 0 4294967295,"
  tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action ok
  tc actions show action gact
    action order 0: gact action pass
    random type none pass val 0
     index 1 ref 1 bind 1
  tc actions add action drop index 1
    RTNETLINK answers: File exists [...]
  tc actions show action gact
    action order 0: gact action pass
     random type none pass val 0
     index 1 ref 2 bind 1
  tc actions add action drop index 1
    RTNETLINK answers: File exists [...]
  tc actions show action gact
    action order 0: gact action pass
     random type none pass val 0
     index 1 ref 3 bind 1

What happens is that in tcf_hash_check(), we check tcf_common for a given
index and increase tcfc_refcnt and conditionally tcfc_bindcnt when we've
found an existing action. Now there are the following cases:

  1) We do a late binding of an action. In that case, we leave the
     tcfc_refcnt/tcfc_bindcnt increased and are done with the ->init()
     handler. This is correctly handeled.

  2) We replace the given action, or we try to add one without replacing
     and find out that the action at a specific index already exists
     (thus, we go out with error in that case).

In case of 2), we have to undo the reference count increase from
tcf_hash_check() in the tcf_hash_check() function. Currently, we fail to
do so because of the 'tcfc_bindcnt > 0' check which bails out early with
an -EPERM error.

Now, while commit 55334a5db5 prevents 'tc actions del action ...' on an
already classifier-bound action to drop the reference count (which could
then become negative, wrap around etc), this restriction only accounts for
invocations outside a specific action's ->init() handler.

One possible solution would be to add a flag thus we possibly trigger
the -EPERM ony in situations where it is indeed relevant.

After the patch, above test cases have correct reference count again.

  However, the bulk of the series is localized to qla2xxx target

  stable code.

  That said, I don't see a good reason to wait another month to get
  these fixes into mainline.

  Beyond the qla2xx specific fixes, this series also includes:

   - bugfix for a long standing use-after-free in iscsi-target during
     TPG shutdown + demo-mode sessions.

   - bugfix for a >= v4.0 regression OOPs in iscsi-target during a

   - bugfix for a >= v4.0 regression hang in iscsi-target for iser

   - bugfix for a iser-target bug where a early CMA REJECTED status

559ed40752 cpufreq: Avoid attempts to create duplicate symbolic links
After commit 87549141d5 (cpufreq: Stop migrating sysfs files on
hotplug) there is a problem with CPUs that share cpufreq policy
objects with other CPUs and are initially offline.

Say CPU1 shares a policy with CPU0 which is online and is registered
first.  As part of the registration process, cpufreq_add_dev() is
called for it.  It creates the policy object and a symbolic link
to it from the CPU1's sysfs directory.  If CPU1 is registered
subsequently and it is offline at that time, cpufreq_add_dev() will
attempt to create a symbolic link to the policy object for it, but
that link is present already, so a warning about that will be
triggered.

To avoid that warning, make cpufreq use an additional CPU mask
containing related CPUs that are actually present for each policy
object.  That mask is initialized when the policy object is populated
after its creation (for the first online CPU using it) and it includes
CPUs from the "policy CPUs" mask returned by the cpufreq driver's
->init() callback that are physically present at that time.  Symbolic
links to the policy are created only for the CPUs in that mask.

If cpufreq_add_dev() is invoked for an offline CPU, it checks the
new mask and only creates the symlink if the CPU was not in it (the
CPU is added to the mask at the same time).

In turn, cpufreq_remove_dev() drops the given CPU from the new mask,
removes its symlink to the policy object and returns, unless it is
the CPU owning the policy object.  In that case, the policy object
is moved to a new CPU's sysfs directory or deleted if the CPU being
removed was the last user of the policy.

While at it, notice that cpufreq_remove_dev() can't fail, because
its return value is ignored, so make it ignore return values from
__cpufreq_remove_dev_prepare() and __cpufreq_remove_dev_finish()
and prevent these functions from aborting on errors returned by
__cpufreq_governor().  Also drop the now unused sif argument from
them.

that the dpms sequence could fail with -ERESTARTSYS because
it was waiting interruptibly for flips. So from now on
allow drivers to fail in their connector dpms callback.

Encoder and crtc dpms callbacks are unaffected.

Changes since v1:
- Update kerneldoc for the drm helper functions.

In intel it's useful to keep track of some state changes with old
crtc state vs new state, for example to disable initial planes or

dfbafc9953 tcp: fix recv with flags MSG_WAITALL | MSG_PEEK
Currently, tcp_recvmsg enters a busy loop in sk_wait_data if called
with flags = MSG_WAITALL | MSG_PEEK.

sk_wait_data waits for sk_receive_queue not empty, but in this case,
the receive queue is not empty, but does not contain any skb that we
can use.

Add a "last skb seen on receive queue" argument to sk_wait_data, so
that it sleeps until the receive queue has new skbs.

caaecdd3d3 inet: frags: remove INET_FRAG_EVICTED and use list_evictor for the test
We can simply remove the INET_FRAG_EVICTED flag to avoid all the flags
race conditions with the evictor and use a participation test for the
evictor list, when we're at that point (after inet_frag_kill) in the
timer there're 2 possible cases:

1. The evictor added the entry to its evictor list while the timer was
waiting for the chainlock
or
2. The timer unchained the entry and the evictor won't see it

In both cases we should be able to see list_evictor correctly due
to the sync on the chainlock.

commit 65ba1f1ec0 ("inet: frags: fix a race between inet_evict_bucket
and inet_frag_kill") describes the bug, but the fix doesn't work reliably.

Problem is that ->flags member can be set on other cpu without chainlock
being held by that task, i.e. the RMW-Cycle can clear INET_FRAG_EVICTED
bit after we put the element on the evictor private list.

We can crash when walking the 'private' evictor list since an element can
be deleted from list underneath the evictor.

2392debc2b ipv4: consider TOS in fib_select_default
fib_select_default considers alternative routes only when
res->fi is for the first alias in res->fa_head. In the
common case this can happen only when the initial lookup
matches the first alias with highest TOS value. This
prevents the alternative routes to require specific TOS.

This patch solves the problem as follows:

- routes that require specific TOS should be returned by
fib_select_default only when TOS matches, as already done
in fib_table_lookup. This rule implies that depending on the
TOS we can have many different lists of alternative gateways
and we have to keep the last used gateway (fa_default) in first
alias for the TOS instead of using single tb_default value.

- as the aliases are ordered by many keys (TOS desc,
fib_priority asc), we restrict the possible results to
routes with matching TOS and lowest metric (fib_priority)
and routes that match any TOS, again with lowest metric.

For example, packet with TOS 8 can not use gw3 (not lowest
metric), gw4 (different TOS) and gw6 (not lowest metric),
all other gateways can be used:

tos 8 via gw1 metric 2 <--- res->fa_head and res->fi
tos 8 via gw2 metric 2
tos 8 via gw3 metric 3
tos 4 via gw4
tos 0 via gw5
tos 0 via gw6 metric 1

e54198657b iscsi-target: Fix iscsit_start_kthreads failure OOPs
This patch fixes a regression introduced with the following commit
in v4.0-rc1 code, where a iscsit_start_kthreads() failure triggers
a NULL pointer dereference OOPs:

    commit 88dcd2dab5
    Author: Nicholas Bellinger <nab@linux-iscsi.org>
    Date:   Thu Feb 26 22:19:15 2015 -0800

        iscsi-target: Convert iscsi_thread_set usage to kthread.h

To address this bug, move iscsit_start_kthreads() immediately
preceeding the transmit of last login response, before signaling
a successful transition into full-feature-phase within existing
iscsi_target_do_tx_login_io() logic.

This ensures that no target-side resource allocation failures can
occur after the final login response has been successfully sent.

Also, it adds a iscsi_conn->rx_login_comp to allow the RX thread
to sleep to prevent other socket related failures until the final
iscsi_post_login_handler() call is able to complete.

Pull networking fixes from David Miller:

 1) Don't use shared bluetooth antenna in iwlwifi driver for management
    frames, from Emmanuel Grumbach.

 2) Fix device ID check in ath9k driver, from Felix Fietkau.

 3) Off by one in xen-netback BUG checks, from Dan Carpenter.

 4) Fix IFLA_VF_PORT netlink attribute validation, from Daniel Borkmann.

 5) Fix races in setting peeked bit flag in SKBs during datagram
    receive.  If it's shared we have to clone it otherwise the value can
    easily be corrupted.  Fix from Herbert Xu.

 6) Revert fec clock handling change, causes regressions.  From Fabio
    Estevam.

 7) Fix use after free in fq_codel and sfq packet schedulers, from WANG
    Cong.

 8) ipvlan bug fixes (memory leaks, missing rcu_dereference_bh, etc.)
    from WANG Cong and Konstantin Khlebnikov.

 9) Memory leak in act_bpf packet action, from Alexei Starovoitov.

10) ARM bpf JIT bug fixes from Nicolas Schichan.

11) Fix backwards compat of ANY_LAYOUT in virtio_net driver, from
    Michael S Tsirkin.

12) Destruction of bond with different ARP header types not handled
    correctly, fix from Nikolay Aleksandrov.

13) Revert GRO receive support in ipv6 SIT tunnel driver, causes
    regressions because the GRO packets created cannot be processed
    properly on the GSO side if we forward the frame.  From Herbert Xu.

14) TCCR update race and other fixes to ravb driver from Sergei
    Shtylyov.

15) Fix SKB leaks in caif_queue_rcv_skb(), from Eric Dumazet.

16) Fix panics on packet scheduler filter replace, from Daniel Borkmann.

17) Make sure AF_PACKET sees properly IP headers in defragmented frames
    (via PACKET_FANOUT_FLAG_DEFRAG option), from Edward Hyunkoo Jee.

18) AF_NETLINK cannot hold mutex in RCU callback, fix from Florian
    Westphal.
