What is happening is that brcmf_pcie_resume() detects a device that
is no longer responsive and it decides to unbind resulting in a
wiphy_unregister() and wiphy_free() call. Now the wiphy instance
remains allocated, because PM needs to call wiphy_resume() for it.
However, brcmfmac already does a kfree() for the struct
cfg80211_registered_device::ops field. Change the checks in
wiphy_resume() to only access the struct cfg80211_registered_device::ops
if the wiphy instance is still registered at this time.

      rocker: fix Wmaybe-uninitialized false-positive · 16b8b6de
      Arnd Bergmann authored 
      gcc-7 reports a warning that earlier versions did not have:

drivers/net/ethernet/rocker/rocker_ofdpa.c: In function 'ofdpa_port_stp_update':
arch/x86/include/asm/string_32.h:79:22: error: '*((void *)&prev_ctrls+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]

   ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/rocker/rocker_ofdpa.c:2218:7: note: '*((void *)&prev_ctrls+4)' was declared here

This is clearly a variation of the warning about 'prev_state' that
was shut up using uninitialized_var().

We can slightly simplify the code and get rid of the warning by unconditionally
saving the prev_state and prev_ctrls variables. The inlined memcpy is not
particularly expensive here, as it just has to read five bytes from one or
two cache lines.

      net: moxa: fix TX overrun memory leak · c2b341a6
      Jonas Jensen authored 
      moxart_mac_start_xmit() doesn't care where tx_tail is, tx_head can
catch and pass tx_tail, which is bad because moxart_tx_finished()
isn't guaranteed to catch up on freeing resources from tx_tail.

Add a check in moxart_mac_start_xmit() stopping the queue at the
end of the circular buffer. Also add a check in moxart_tx_finished()
waking the queue if the buffer has TX_WAKE_THRESHOLD or more
free descriptors.

While we're at it, move spin_lock_irq() to happen before our
descriptor pointer is assigned in moxart_mac_start_xmit().

      isdn: kcapi: avoid uninitialized data · af109a2c
      Arnd Bergmann authored 
      gcc-7 points out that the AVMB1_ADDCARD ioctl results in an unintialized
value ending up in the cardnr parameter:

drivers/isdn/capi/kcapi.c: In function 'old_capi_manufacturer':
drivers/isdn/capi/kcapi.c:1042:24: error: 'cdef.cardnr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   cparams.cardnr = cdef.cardnr;

This has been broken since before the start of the git history, so
either the value is not used for anything important, or the ioctl
command doesn't get called in practice.

Setting the cardnr to zero avoids the warning and makes sure
we have consistent behavior.

      sctp: change to save MSG_MORE flag into assoc · f9ba3501
      Xin Long authored 
      David Laight noticed the support for MSG_MORE with datamsg->force_delay
didn't really work as we expected, as the first msg with MSG_MORE set
would always block the following chunks' dequeuing.

This Patch is to rewrite it by saving the MSG_MORE flag into assoc as
David Laight suggested.

asoc->force_delay is used to save MSG_MORE flag before a msg is sent.
All chunks in queue would not be sent out if asoc->force_delay is set
by the msg with MSG_MORE flag, until a new msg without MSG_MORE flag
clears asoc->force_delay.

Note that this change would not affect the flush is generated by other
triggers, like asoc->state != ESTABLISHED, queue size > pmtu etc.

v1->v2:
  Not clear asoc->force_delay after sending the msg with MSG_MORE flag.

      net: ipconfig: fix ic_close_devs() use-after-free · ffefb6f4
      Mark Rutland authored 
      Our chosen ic_dev may be anywhere in our list of ic_devs, and we may
free it before attempting to close others. When we compare d->dev and
ic_dev->dev, we're potentially dereferencing memory returned to the
allocator. This causes KASAN to scream for each subsequent ic_dev we
check.

As there's a 1-1 mapping between ic_devs and netdevs, we can instead
compare d and ic_dev directly, which implicitly handles the !ic_dev
case, and avoids the use-after-free. The ic_dev pointer may be stale,
but we will not dereference it.

Original splat:

The code is actually correct since we always set all 16 bits of the
port_vlan field, but gcc correctly points out that the first
access does contain uninitialized data.

This initializes the field to zero first before setting the
individual bits.

      net: hns: fix uninitialized data use · a17f1861
      Arnd Bergmann authored 
      When dev_dbg() is enabled, we print uninitialized data, as gcc-7.0.1
now points out:

ethernet/hisilicon/hns/hns_dsaf_main.c: In function 'hns_dsaf_set_promisc_tcam':
ethernet/hisilicon/hns/hns_dsaf_main.c:2947:75: error: 'tbl_tcam_data.low.val' may be used uninitialized in this function [-Werror=maybe-uninitialized]
ethernet/hisilicon/hns/hns_dsaf_main.c:2947:75: error: 'tbl_tcam_data.high.val' may be used uninitialized in this function [-Werror=maybe-uninitialized]

We also pass the data into hns_dsaf_tcam_mc_cfg(), which might later
use it (not sure about that), so it seems safer to just always initialize
the tbl_tcam_data structure.

      The ECC bit positions that describe whether the ECC interrupt is for
Tx, Rx or descriptor memory and whether the it is a single correctable
or double detected error were defined in incorrectly (reversed order).
Fix the bit position definitions for these settings so that the proper
ECC handling is performed.
