Pull tracing updates from Steven Rostedt:
"Some clean ups and small fixes, but the biggest change is the addition
of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints.
Tracepoints have helper functions for the TP_printk() called
__print_symbolic() and __print_flags() that lets a numeric number be
displayed as a a human comprehensible text. What is placed in the
TP_printk() is also shown in the tracepoint format file such that user
space tools like perf and trace-cmd can parse the binary data and
express the values too. Unfortunately, the way the TRACE_EVENT()
macro works, anything placed in the TP_printk() will be shown pretty
much exactly as is. The problem arises when enums are used. That's
because unlike macros, enums will not be changed into their values by
the C pre-processor. Thus, the enum string is exported to the format
file, and this makes it useless for user space tools.
The TRACE_DEFINE_ENUM() solves this by converting the enum strings in
the TP_printk() format into their number, and that is what is shown to
user space. For example, the tracepoint tlb_flush currently has this
in its format file:
__print_symbolic(REC->reason,
{ TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" },
{ TLB_REMOTE_SHOOTDOWN, "remote shootdown" },
{ TLB_LOCAL_SHOOTDOWN, "local shootdown" },
{ TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" })
After adding:
TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH);
TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN);
TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN);
TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN);
Its format file will contain this:
__print_symbolic(REC->reason,
{ 0, "flush on task switch" },
{ 1, "remote shootdown" },
{ 2, "local shootdown" },
{ 3, "local mm shootdown" })"

Every tracing file must have its own TRACE_SYSTEM defined.
The brcmsmac tracepoint header broke this and added in the middle
of the file:
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac_tx
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac_msg
Unfortunately, this broke new code in the ftrace infrastructure.
Moving each of these TRACE_SYSTEMs into their own trace file with
just one TRACE_SYSTEM per file fixes the issue.

In this routine, kzalloc allocates a memory block. This allocation is
freed in the error paths, but not in the normal exit, thus the allocation
is leaked.

Transmission of an AP beacon does not call the TX interrupt service routine,
which usually does the cleanup. Instead, cleanup is handled in a tasklet
completion routine. Unfortunately, this routine has a serious bug in that it does
not release the DMA mapping before it frees the skb, thus one IOMMU mapping is
leaked for each beacon. The test system failed with no free IOMMU mapping slots
approximately one hour after hostapd was used to start an AP.
This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30.

When the driver callback returns that it's out of space for new
stations, the mac80211 IBSS code still keeps the station so it
doesn't try to add it over and over again.
Since the rate scaling algorithm is separate in mac80211, it also
invokes the rate scaling algorithm for such stations. It doesn't
know that our rate scaling algorithm is tightly integrated with
the MVM code and relies on those data structures, and it cannot
as the abstraction doesn't allow for it.
This leads to crashes when the rate scaling algorithm tries to
use uninitialized data, notably the mvmsta->vif pointer.
Protect against this in the rate scaling algorithm. We cannot get
good rates with such peers anyway since the firmware cannot do
anything with them.
This should fix https://bugzilla.kernel.org/show_bug.cgi?id=93461

The assumption before this patch was that we don't need to
run again the INIT firmware after the system booted. The
INIT firmware runs calibrations which impact the physical
layer's behavior.
Users reported that it may be helpful to run these
calibrations again every time the interface is brought up.
The penatly is minimal, since the calibrations run fast.

sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
should be updated, or if beacons have been enabled already.
With the current code (depending on the order of calls), beacons often
do not get enabled in an AP+STA setup.
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
bitmask of enabled beacon slots.

If this situation ever happens, the mac80211 state machine gets
confused because it never clears csa_active. There was a separate
bug that lead to this happening with a working connection, but it
isn't very robust to try to keep the connection up in this case.
When removing the time event the CSA essentially procedure stops,
so the safest thing to do is to disconnect in this case.

mac80211 now informs the driver when to drop the packets
upon flush(). This will happen before disconnecting, or
before we shut down the interface. We can now rely on this
to drop all the packets including the VO queues.
When mac80211 sets drop to false, wait for all the queues
to be empty.

The commit below introduced an unsafe dereference of
mvmvif->phy_ctxt. It can be NULL even if we hold the mutex.
We can be handling a BT Coex notification while the vif has
already been unassigned. This can happen since the BT Coex
notification is hanled asynchronuously: we can have started
to handle the BT Coex notification trying to acquire the
mutex while the unassign flow already got it. The BT Coex
notification handling will wait for the mutext. I'll get it
later, but then mvmvif->phy_ctxt will be NULL.

Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.
This patch also removes a magic number.

Correct two problems with the error handling when using the netlink
forwarding API: first, the netlink skb is never freed if nla_put()
fails; and second, genlmsg_unicast() can fail if the netlink socket
is full. In the latter case, the corresponding data skb is not counted
as a drop and userspace programs like wmediumd will see TCP stalls

clear things up so the next scans will work again. To do so, don't
return immediately in case of failures, but call
ieee80211_scan_completed() and clear the scan_status flags.

Pull kconfig updates from Michal Marek:
"Yann E Morin was supposed to take over kconfig maintainership, but
this hasn't happened. So I'm sending a few kconfig patches that I
collected:
- Fix for missing va_end in kconfig
- merge_config.sh displays used if given too few arguments
- s/boolean/bool/ in Kconfig files for consistency, with the plan to
only support bool in the future"
* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig: use va_end to match corresponding va_start
merge_config.sh: Display usage if given too few arguments
kconfig: use bool instead of boolean for type definition attributes

Pull networking updates from David Miller:
1) Missing netlink attribute validation in nft_lookup, from Patrick
McHardy.
2) Restrict ipv6 partial checksum handling to UDP, since that's the
only case it works for. From Vlad Yasevich.
3) Clear out silly device table sentinal macros used by SSB and BCMA
drivers. From Joe Perches.
4) Make sure the remote checksum code never creates a situation where
the remote checksum is applied yet the tunneling metadata describing
the remote checksum transformation is still present. Otherwise an
external entity might see this and apply the checksum again. From
Tom Herbert.
5) Use msecs_to_jiffies() where applicable, from Nicholas Mc Guire.
6) Don't explicitly initialize timer struct fields, use setup_timer()
and mod_timer() instead. From Vaishali Thakkar.
7) Don't invoke tg3_halt() without the tp->lock held, from Jun'ichi
Nomura.
8) Missing __percpu annotation in ipvlan driver, from Eric Dumazet.
9) Don't potentially perform skb_get() on shared skbs, also from Eric
Dumazet.
10) Fix COW'ing of metrics for non-DST_HOST routes in ipv6, from Martin
KaFai Lau.
11) Fix merge resolution error between the iov_iter changes in vhost and
some bug fixes that occurred at the same time. From Jason Wang.
12) If rtnl_configure_link() fails we have to perform a call to
->dellink() before unregistering the device. From WANG Cong.

printk and friends can now format bitmaps using '%*pb[l]'. cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

In commit e9538cf4f907 ("rtlwifi: Fix error when accessing unmapped memory
in skb"), a printk was included to indicate that the condition had been
reached. There is now enough evidence from other users that the fix is
working. That logging statement can now be removed.

their argument is NULL and then return immediately. Thus the test around

The functions kfree() and release_firmware() were called in a few cases
by the cw1200_load_firmware_cw1200() function during error handling even if
the passed variables contained still a null pointer.
Corresponding implementation details could be improved by adjustments for
jump targets.
