Normally symbols are read from the DSO and adjusted, if need be, so that
the symbol start matches the file offset in the DSO file (we want the
file offset because that is what we know from MMAP events). That is done
by dso__load_sym() which inserts the symbols *after* adjusting them.
In the case of kcore, the symbols have been read from kallsyms and the
symbol start is the memory address. The symbols have to be adjusted to
match the kcore file offsets. dso__split_kallsyms_for_kcore() does that,
but now the adjustment is being done *after* the symbols have been
inserted. It appears dso__split_kallsyms_for_kcore() was assuming that
changing the symbol start would not change the order in the rbtree -
which is, of course, not guaranteed.

Building dwmac-ipq806x on a 64-bit architecture produces a harmless
warning from gcc:
stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe':
include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow]
val = QSGMII_PHY_CDR_EN |
stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN'
#define QSGMII_PHY_CDR_EN BIT(0)
#define BIT(nr) (1UL << (nr))
This is a result of the type conversion rules in C, when we take the
logical OR of multiple different types. In particular, we have
and unsigned long
QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
and a signed int
0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
which together gives a signed long value
0xffffffffc0000001l
and when this is passed into a function that takes an unsigned int type,
gcc warns about the signed overflow and the loss of the upper 32-bits that
are all ones.
This patch adds 'ul' type modifiers to the literal numbers passed in
here, so now the expression remains an 'unsigned long' with the upper
bits all zero, and that avoids the signed overflow and the warning.

There are several sound drivers that 'select ZONE_DMA'. This is
backwards as ZONE_DMA is an architecture capability exported to drivers.
Switch the polarity of the dependency to disable these drivers when the
architecture does not support ZONE_DMA. This was discovered in the
context of testing/enabling devm_memremap_pages() which depends on
ZONE_DEVICE. ZONE_DEVICE in turn depends on !ZONE_DMA.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree. This
large batch that includes fixes for ipset, netfilter ingress, nf_tables
dynamic set instantiation and a longstanding Kconfig dependency problem.
More specifically, they are:
1) Add missing check for empty hook list at the ingress hook, from
Florian Westphal.
2) Input and output interface are swapped at the ingress hook,
reported by Patrick McHardy.
3) Resolve ipset extension alignment issues on ARM, patch from Jozsef
Kadlecsik.
4) Fix bit check on bitmap in ipset hash type, also from Jozsef.
5) Release buckets when all entries have expired in ipset hash type,
again from Jozsef.
6) Oneliner to initialize conntrack tuple object in the PPTP helper,
otherwise the conntrack lookup may fail due to random bits in the
structure holes, patch from Anthony Lineham.
7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann.
8) Fix Kconfig dependency problems with TPROXY, socket and dup, also
from Arnd.
9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters
from atomic context, this is required by the follow up fix for
nf_tables.
10) Fix crash from the dynamic set expression, we have to add new clone
operation that should be defined when a simple memcpy is not enough.
This resolves a crash when using per-cpu counters with new Patrick
McHardy's flow table nft support.

The HDMI codec parser may create a phantom jack, but the helper
function snd_hda_jack_add_kctl() treats always as a normal jack. This
is superfluous as the jack query is executed at each time the jack
sync is performed.
Since the HDMI codec parser is the only caller of this function, it's
easier to change back this directly calling the original
__snd_hda_jack_add_kctl() with phantom_jack parameter.

its si_code and si_errno are inverted, we can still make it as
close to the generic version as possible. This makes it easier
to update when new members are added to siginfo_t.
The main changes are adding a missing _sigsys union member and
eliminating the unused _irix_sigchld one.

This fixes CVE-2015-5327. It affects kernels from 4.3-rc1 onwards.
Fix the X.509 time validation to use month number-1 when looking up the
number of days in that month. Also put the month number validation before
doing the lookup so as not to risk overrunning the array.
This can be tested by doing the following:
cat <<EOF | openssl x509 -outform DER | keyctl padd asymmetric "" @s

"Paolo,
I have two fixes for HV KVM which I would like to have included in
v4.4-rc1. The first one is a fix for a bug identified by Red Hat
which causes occasional guest crashes. The second one fixes a bug
which causes host stalls and timeouts under certain circumstances when
the host is configured for static 2-way micro-threading mode."
KVM uses the get_xsave_addr() function in a different fashion from
the native kernel, in that the 'xsave' parameter belongs to guest vcpu,
not the currently running task.
But 'xsave' is replaced with current task's (host) xsave structure, so
get_xsave_addr() will incorrectly return the bad xsave address to KVM.
Fix it so that the passed in 'xsave' address is used - as intended
originally.

(This should have gone to LKML originally. Sorry for the extra
noise, folks on the cc.)
Background:
Signal frames on x86 have two formats:
1. For 32-bit executables (whether on a real 32-bit kernel or
under 32-bit emulation on a 64-bit kernel) we have a
'fpregset_t' that includes the "FSAVE" registers.
2. For 64-bit executables (on 64-bit kernels obviously), the
'fpregset_t' is smaller and does not contain the "FSAVE"
state.
When creating the signal frame, we have to be aware of whether
we are running a 32 or 64-bit executable so we create the
correct format signal frame.
Problem:
save_xstate_epilog() uses 'fx_sw_reserved_ia32' whenever it is
called for a 32-bit executable. This is for real 32-bit and
ia32 emulation.
But, fpu__init_prepare_fx_sw_frame() only initializes
'fx_sw_reserved_ia32' when emulation is enabled, *NOT* for real
32-bit kernels.
This leads to really wierd situations where 32-bit programs
lose their extended state when returning from a signal handler.
The kernel copies the uninitialized (zero) 'fx_sw_reserved_ia32'
out to userspace in save_xstate_epilog(). But when returning
from the signal, the kernel errors out in check_for_xstate()
when it does not see FP_XSTATE_MAGIC1 present (because it was
zeroed). This leads to the FPU/XSAVE state being initialized.
For MPX, this leads to the most permissive state and means we
silently lose bounds violations. I think this would also mean
that we could lose *ANY* FPU/SSE/AVX state. I'm not sure why
no one has spotted this bug.
I believe this was broken by:
72a671ced6 ("x86, fpu: Unify signal handling code paths for x86 and x86_64 kernels")
way back in 2012.

I received a bug report that running 32-bit MPX binaries on
64-bit kernels was broken. I traced it down to this little code
snippet. We were switching our "number of bounds directory
entries" calculation correctly. But, we didn't switch the other
side of the calculation: the virtual space size.
This meant that we were calculating an absurd size for
bd_entry_virt_space() on 32-bit because we used the 64-bit
virt_space.
This was _also_ broken for 32-bit kernels running on 64-bit
hardware since boot_cpu_data.x86_virt_bits=48 even when running
in 32-bit mode.
Correct that and properly handle all 3 possible cases:
1. 32-bit binary on 64-bit kernel
2. 64-bit binary on 64-bit kernel
3. 32-bit binary on 32-bit kernel
This manifested in having bounds tables not properly unmapped.
It "leaked" memory but had no functional impact otherwise.

When you call get_user(foo, bar), you effectively do a
copy_from_user(&foo, bar, sizeof(*bar));
Note that the sizeof() is implicit.
When we reach out to userspace to try to zap an entire "bounds
table" we need to go read a "bounds directory entry" in order to
locate the table's address. The size of a "directory entry"
depends on the binary being run and is always the size of a
pointer.
But, when we have a 64-bit kernel and a 32-bit application, the
directory entry is still only 32-bits long, but we fetch it with
a 64-bit pointer which makes get_user() does a 64-bit fetch.
Reading 4 extra bytes isn't harmful, unless we are at the end of
and run off the table. It might also cause the zero page to get
faulted in unnecessarily even if you are not at the end.
Fix it up by doing a special 32-bit get_user() via a cast when
we have 32-bit userspace.

According to SPC-4, in a Mode Select, the PS bit in Mode Pages is
reserved and must be set to 0 by the driver. In the sd implementation,
function cache_type_store does a Mode Sense, which might set the PS bit
on the read buffer, followed by a Mode Select, which receives the same
buffer, without explicitly clearing the PS bit. So, in cases where
target supports saving the Mode Page to a non-volatile location, we end
up doing a Mode Select with the PS bit set, which could cause an illegal
request error if the target is checking this.
This was observed on a new firmware change, which was subsequently
reverted, but this changes sd.c to be more compliant with SPC-4.
This patch clears the PS bit in the buffer returned by Mode Select,
right before it is used in the Mode Select command.

As defined in 4.6.9 of SAM-4, the encoding of LUN is
on 5 bits (max_lun=32) and the current value is only 8.
Set max_lun to IBMVSCSI_MAX_LUN (32).

As devices with values greater than that are silently ignored,
this gives some hints to the sys admin to know why he doesn't see
his devices...
