91dd28e913 net: xen-netback: fix return type of ndo_start_xmit function
[ Upstream commit a9ca7f17c6 ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

c31ab7dcc7 libata: have ata_scsi_rw_xlat() fail invalid passthrough requests
commit 2d72715017 upstream.

For passthrough requests, libata-scsi takes what the user passes in
as gospel. This can be problematic if the user fills in the CDB
incorrectly. One example of that is in request sizes. For read/write
commands, the CDB contains fields describing the transfer length of
the request. These should match with the SG_IO header fields, but
libata-scsi currently does no validation of that.

Check that the number of blocks in the CDB for passthrough requests
matches what was mapped into the request. If the CDB asks for more
data then the validated SG_IO header fields, error it.

9059234e98 uprobes/x86: Prohibit probing on MOV SS instruction
commit 13ebe18c94 upstream.

Since MOV SS and POP SS instructions will delay the exceptions until the
next instruction is executed, single-stepping on it by uprobes must be
prohibited.

uprobe already rejects probing on POP SS (0x1f), but allows probing on MOV
SS (0x8e and reg == 2).  This checks the target instruction and if it is
MOV SS or POP SS, returns -ENOTSUPP to reject probing.

fd551aa3b7 kprobes/x86: Prohibit probing on exception masking instructions
commit ee6a7354a3 upstream.

Since MOV SS and POP SS instructions will delay the exceptions until the
next instruction is executed, single-stepping on it by kprobes must be
prohibited.

However, kprobes usually executes those instructions directly on trampoline
buffer (a.k.a. kprobe-booster), except for the kprobes which has
post_handler. Thus if kprobe user probes MOV SS with post_handler, it will
do single-stepping on the MOV SS.

This means it is safe that if it is used via ftrace or perf/bpf since those
don't use the post_handler.

Anyway, since the stack switching is a rare case, it is safer just
rejecting kprobes on such instructions.

a3ac4961f7 x86/atomic: Fix smp_mb__{before,after}_atomic()
commit 69d927bba3 upstream.

Recent probing at the Linux Kernel Memory Model uncovered a
'surprise'. Strongly ordered architectures where the atomic RmW
primitive implies full memory ordering and
smp_mb__{before,after}_atomic() are a simple barrier() (such as x86)
fail for:

	*x = 1;
	atomic_inc(u);
	smp_mb__after_atomic();
	r0 = *y;

Because, while the atomic_inc() implies memory order, it
(surprisingly) does not provide a compiler barrier. This then allows
the compiler to re-order like so:

	atomic_inc(u);
	*x = 1;
	smp_mb__after_atomic();
	r0 = *y;

Which the CPU is then allowed to re-order (under TSO rules) like:

	atomic_inc(u);
	r0 = *y;
	*x = 1;

And this very much was not intended. Therefore strengthen the atomic
RmW ops to include a compiler barrier.

NOTE: atomic_{or,and,xor} and the bitops already had the compiler
barrier.

We observe there are two memory controllers per socket, with a limit
of 16. Raise the maximum number of memory controllers from 16 to 2 *
MAX_NUMNODES (1024).

[ bp: This is just a band-aid fix until we've sorted out the whole issue
  with the bus_type association and handling in EDAC and can get rid of
  this arbitrary limit. ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',

89b4a08797 scsi: libsas: always unregister the old device if going to discover new
[ Upstream commit 32c850bf58 ]

If we went into sas_rediscover_dev() the attached_sas_addr was already insured
not to be zero. So it's unnecessary to check if the attached_sas_addr is zero.

And although if the sas address is not changed, we always have to unregister
the old device when we are going to register a new one. We cannot just leave
the device there and bring up the new.

b92f47cb33 vfio/pci: Mask buggy SR-IOV VF INTx support
[ Upstream commit db04264fe9 ]

The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support.  It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace.  Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.

As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

3194c8738e coresight: tmc: Fix byte-address alignment for RRP
[ Upstream commit e7753f3937 ]

>From the comment in the code, it claims the requirement for byte-address
alignment for RRP register: 'for 32-bit, 64-bit and 128-bit wide trace
memory, the four LSBs must be 0s. For 256-bit wide trace memory, the
five LSBs must be 0s'.  This isn't consistent with the program, the
program sets five LSBs as zeros for 32/64/128-bit wide trace memory and
set six LSBs zeros for 256-bit wide trace memory.

After checking with the CoreSight Trace Memory Controller technical
reference manual (ARM DDI 0461B, section 3.3.4 RAM Read Pointer
Register), it proves the comment is right and the program does wrong
setting.

This patch fixes byte-address alignment for RRP by following correct
definition in the technical reference manual.

0b3295d6c5 coresight: etm4x: Configure EL2 exception level when kernel is running in HYP
[ Upstream commit b860801e32 ]

For non-VHE systems host kernel runs at EL1 and jumps to EL2 whenever
hypervisor code should be executed. In this case ETM4x driver must
restrict configuration to EL1 when it setups kernel tracing.
However, there is no separate hypervisor privilege level when VHE
is enabled, the host kernel runs at EL2.

This patch fixes configuration of TRCACATRn register for VHE systems
so that ETM_EXLEVEL_NS_HYP bit is used instead of ETM_EXLEVEL_NS_OS
to on/off kernel tracing. At the same time, it moves common code
to new helper.

200b789f66 coresight: Fix handling of sinks
[ Upstream commit c71369de02 ]

The coresight components could be operated either in sysfs mode or in perf
mode. For some of the components, the mode of operation doesn't matter as
they simply relay the data to the next component in the trace path. But for
sinks, they need to be able to provide the trace data back to the user.
Thus we need to make sure that "mode" is handled appropriately. e.g,
the sysfs mode could have multiple sources driving the trace data, while
perf mode doesn't allow sharing the sink.

The coresight_enable_sink() however doesn't really allow this check to
trigger as it skips the "enable_sink" callback if the component is
already enabled, irrespective of the mode. This could cause mixing
of data from different modes or even same mode (in perf), if the
sources are different. Also, if we fail to enable the sink while
enabling a path (where sink is the first component enabled),
we could end up in disabling the components in the "entire"
path which were not enabled in this trial, causing disruptions
in the existing trace paths.

ae0d646108 usb: gadget: uvc: Only halt video streaming endpoint in bulk mode
[ Upstream commit 8dbf9c7abe ]

When USB requests for video data fail to be submitted, the driver
signals a problem to the host by halting the video streaming endpoint.
This is only valid in bulk mode, as isochronous transfers have no
handshake phase and can't thus report a stall. The usb_ep_set_halt()
call returns an error when using isochronous endpoints, which we happily
ignore, but some UDCs complain in the kernel log. Fix this by only
trying to halt the endpoint in bulk mode.

14b802670a x86/CPU: Use correct macros for Cyrix calls
[ Upstream commit 03b099bdcd ]

There are comments in processor-cyrix.h advising you to _not_ make calls
using the deprecated macros in this style:

  setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80);

This is because it expands the macro into a non-functioning calling
sequence. The calling order must be:

  outb(CX86_CCR2, 0x22);
  inb(0x23);

From the comments:

 * When using the old macros a line like
 *   setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
 * gets expanded to:
 *  do {
 *    outb((CX86_CCR2), 0x22);
 *    outb((({
 *        outb((CX86_CCR2), 0x22);
 *        inb(0x23);
 *    }) | 0x88), 0x23);
 *  } while (0);

The new macros fix this problem, so use them instead.
