The trace event start up selftests fails when the trace benchmark is
enabled, because it is disabled during boot. It really only needs to be
disabled before scheduling is set up, as it creates a thread.

Trace events are enabled very early on boot up via the boot command line
parameter. The benchmark tool creates a new thread to perform the trace
event benchmarking. But at start up, it is called before scheduling is set
up and because it creates a new thread before the init thread is created,
this crashes the kernel.
Have the benchmark fail to register when started via the kernel command
line.
Also, since the registering of a tracepoint now can handle failure cases,
return -ENOMEM instead of warning if the thread cannot be created.

Some tracepoints have a registration function that gets enabled when the
tracepoint is enabled. There may be cases that the registraction function
must fail (for example, can't allocate enough memory). In this case, the
tracepoint should also fail to register, otherwise the user would not know
why the tracepoint is not working.

When mac80211 abandons an association attempt, it may free
all the data structures, but inform cfg80211 and userspace
about it only by sending the deauth frame it received, in
which case cfg80211 has no link to the BSS struct that was
used and will not cfg80211_unhold_bss() it.
Fix this by providing a way to inform cfg80211 of this with
the BSS entry passed, so that it can clean up properly, and
use this ability in the appropriate places in mac80211.
This isn't ideal: some code is more or less duplicated and
tracing is missing. However, it's a fairly small change and
it's thus easier to backport - cleanups can come later.

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned
and the random MAC address to be used when privacy is enabled. When both
the features are enabled, both the BSSID and the local MAC address were
getting same value causing Probe Request frames to go with unintended
DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID
attribute to set the specific BSSID (which was the more recent addition
in cfg80211) for a scan.
Backwards compatibility with old userspace software is maintained to
some extent by allowing NL80211_ATTR_MAC to be used to set the specific
BSSID when scanning without enabling random MAC address use.
Scanning with random source MAC address was introduced by commit
ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses
for scan") and the issue was introduced with the addition of the second
user for the same attribute in commit 818965d39177 ("cfg80211: Allow a

The clocksource delta to nanoseconds conversion is using signed math, but
the delta is unsigned. This makes the conversion space smaller than
necessary and in case of a multiplication overflow the conversion can
become negative. The conversion is done with scaled math:
s64 nsec_delta = ((s64)clkdelta * clk->mult) >> clk->shift;
Shifting a signed integer right obvioulsy preserves the sign, which has
interesting consequences:
- Time jumps backwards
- __iter_div_u64_rem() which is used in one of the calling code pathes
will take forever to piecewise calculate the seconds/nanoseconds part.
This has been reported by several people with different scenarios:
David observed that when stopping a VM with a debugger:
"It was essentially the stopped by debugger case. I forget exactly why,
but the guest was being explicitly stopped from outside, it wasn't just
scheduling lag. I think it was something in the vicinity of 10 minutes
stopped."
When lifting the stop the machine went dead.
The stopped by debugger case is not really interesting, but nevertheless it
would be a good thing not to die completely.
But this was also observed on a live system by Liav:
"When the OS is too overloaded, delta will get a high enough value for the
msb of the sum delta * tkr->mult + tkr->xtime_nsec to be set, and so
after the shift the nsec variable will gain a value similar to
0xffffffffff000000."
Unfortunately this has been reintroduced recently with commit 6bd58f09e1d8
("time: Add cycles to nanoseconds translation"). It had been fixed a year
ago already in commit 35a4933a8959 ("time: Avoid signed overflow in
timekeeping_get_ns()").
Though it's not surprising that the issue has been reintroduced because the
function itself and the whole call chain uses s64 for the result and the
propagation of it. The change in this recent commit is subtle:
s64 nsec;
- nsec = (d * m + n) >> s:
+ nsec = d * m + n;
+ nsec >>= s;
d being type of cycle_t adds another level of obfuscation.
This wouldn't have happened if the previous change to unsigned computation
would have made the 'nsec' variable u64 right away and a follow up patch
had cleaned up the whole call chain.
There have been patches submitted which basically did a revert of the above
patch leaving everything else unchanged as signed. Back to square one. This
spawned a admittedly pointless discussion about potential users which rely
on the unsigned behaviour until someone pointed out that it had been fixed
before. The changelogs of said patches added further confusion as they made
finally false claims about the consequences for eventual users which expect
signed results.
Despite delta being cycle_t, aka. u64, it's very well possible to hand in
a signed negative value and the signed computation will happily return the
correct result. But nobody actually sat down and analyzed the code which
was added as user after the propably unintended signed conversion.
Though in sensitive code like this it's better to analyze it proper and
make sure that nothing relies on this than hunting the subtle wreckage half
a year later. After analyzing all call chains it stands that no caller can
hand in a negative value (which actually would work due to the s64 cast)
and rely on the signed math to do the right thing.
Change the conversion function to unsigned math. The conversion of all call
chains is done in a follow up patch.
This solves the starvation issue, which was caused by the negative result,
but it does not solve the underlying problem. It merily procrastinates
it. When the timekeeper update is deferred long enough that the unsigned
multiplication overflows, then time going backwards is observable again.
It does neither solve the issue of clocksources with a small counter width
which will wrap around possibly several times and cause random time stamps
to be generated. But those are usually not found on systems used for
virtualization, so this is likely a non issue.
I took the liberty to claim authorship for this simply because
analyzing all callsites and writing the changelog took substantially
more time than just making the simple s/s64/u64/ change and ignore the
rest.

On systems with sufficiently large e820 tables, and several IOAPICs, it
is possible for the XENMEM_machine_memory_map callback (and its
counterpart, XENMEM_memory_map) to attempt to return an e820 table with
more than 128 entries. This callback adds entries to the BIOS-provided
e820 table to account for IOAPIC registers, which, on sufficiently large
systems, can result in an e820 table that is too large to copy back into
xen_e820_map.
This change simply increases the size of xen_e820_map to E820_X_MAX to
ensure that there is enough room to store the entire e820 map returned
from this callback.

It's really not necessary to limit E820_X_MAX to 128 in the non-EFI
case. This commit drops E820_X_MAX's dependency on CONFIG_EFI, so that
E820_X_MAX is always at least slightly larger than E820MAX.
The real motivation behind this is actually to prevent some issues in
the Xen kernel, where the XENMEM_machine_memory_map hypercall can
produce an e820 map larger than 128 entries, even on systems where the
original e820 table was quite a bit smaller than that, depending on how
many IOAPICs are installed on the system.

Commit 6552321831dc ("xfs: remove i_iolock and use i_rwsem in the
VFS inode instead") introduced a regression that truncate(2) doesn't
check on new size, so it succeeds even if the new size exceeds the
current resource limit. Because xfs_setattr_size() was used instead
of xfs_vn_setattr_size(), and the latter calls xfs_vn_change_ok()
first to do sanity check on permission and new size.
This is found by truncate03 test from ltp, and the following is a
simplified reproducer:
#!/bin/bash
dev=/dev/sda5
mnt=/mnt/xfs
mkfs -t xfs -f $dev
mount $dev $mnt
# set max file size to 16k
ulimit -f 16

If that fails, we copy the (empty) attribute into a leaf attribute,

If we encounter this during log replay, the verifier will fail.
So add a test to ignore this part of the leaf attr verification

The array for initializing the cle is set up on the stack with

Looking a bit deeper at the usage, I noticed that the only modification
of the data is in dead code, as we don't even use the cle module
for phy_mode other than PHY_INTERFACE_MODE_XGMII. This means we
can simply mark the structure constant and access it directly rather
than passing the pointer down through another structure, making
the code more efficient at the same time as avoiding the
warning.

We have the special %pad format for printing dma_addr_t, so use that
to print the correct address and avoid the warning.

git://anongit.freedesktop.org/git/drm-misc into drm-next
Another pile of misc stuff, final one for 4.10. If there's some serious
bugfix still I'll send you a pull for drm-misc-next-fixes (like we do with
intel), otherwise this is it and next pull next year for 4.11.
Most interesting bits are probably Chris' fb helper fixes against mst
hotplug oopses.

Florian Fainelli says:
====================
net: ethernet: Make sure we set dev->dev.parent
This patch series builds atop:
ec988ad78ed6d184a7f4ca6b8e962b0e8f1de461 ("phy: Don't increment MDIO
bus refcount unless it's a different owner")
FMAN is the one that potentially needs patching as well (call
SET_NETDEV_DEV), but there appears to be no way that init_phy is
called right now, or there is not such an in-tree user. Madalin, can
you comment on that?

The TI CPMAC driver calls into PHYLIB which now checks for
net_device->dev.parent, so make sure we do set it before calling into
any MDIO/PHYLIB related function.
Fixes: ec988ad78ed6 ("phy: Don't increment MDIO bus refcount unless it's a different owner")
