      dm ioctl: prevent stack leak in dm ioctl call · d9684d5c
      Adrian Salido authored 
      commit 4617f564 upstream.

When calling a dm ioctl that doesn't process any data
(IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct
dm_ioctl are left initialized.  Current code is incorrectly extending
the size of data copied back to user, causing the contents of kernel
stack to be leaked to user.  Fix by only copying contents before data
and allow the functions processing the ioctl to override.

      gfs2: remove IS_ERR_VALUE abuse · 12bf6fbc
      Arnd Bergmann authored 
      Picked from commit 287980e4 ("remove lots
of IS_ERR_VALUE abuses") upstream.

The original fix that was backported to 3.18 already addressed the warning
in some configurations, but not in others, leaving us with the same output:

../fs/gfs2/dir.c: In function 'get_first_leaf':
../fs/gfs2/dir.c:768:9: warning: 'leaf_no' may be used uninitialized in this function [-Wmaybe-uninitialized]
   error = get_leaf(dip, leaf_no, bh_out);
         ^

../fs/gfs2/dir.c:987:8: warning: 'leaf_no' may be used uninitialized in this function [-Wmaybe-uninitialized]

This takes the approach that we took in later versions in mainline,
but does not backport the entire patch, as that would be too large
for stable and IIRC caused regressions in other drivers.

      e1000e: fix call to do_div() to use u64 arg · 8d86ef0c
      Jeff Kirsher authored 
      commit 30544af5 upstream.

We were using s64 for lat_ns (latency nano-second value) since in
our calculations a negative value could be a resultant.  For negative
values, we then assign lat_ns to be zero, so the value passed to
do_div() was never negative, but do_div() expects the argument type
to be u64, so do a cast to resolve a compile warning seen on
PowerPC.

      cpumask_set_cpu_local_first => cpumask_local_spread, lament · 706470a2
      Rusty Russell authored 
      commit f36963c9 upstream.

da91309e (cpumask: Utility function to set n'th cpu...) created a
genuinely weird function.  I never saw it before, it went through DaveM.
(He only does this to make us other maintainers feel better about our own
mistakes.)

cpumask_set_cpu_local_first's purpose is say "I need to spread things
across N online cpus, choose the ones on this numa node first"; you call
it in a loop.

It can fail.  One of the two callers ignores this, the other aborts and
fails the device open.

It can fail in two ways: allocating the off-stack cpumask, or through a
convoluted codepath which AFAICT can only occur if cpu_online_mask
changes.  Which shouldn't happen, because if cpu_online_mask can change
while you call this, it could return a now-offline cpu anyway.

It contains a nonsensical test "!cpumask_of_node(numa_node)".  This was
drawn to my attention by Geert, who said this causes a warning on Sparc.
It sets a single bit in a cpumask instead of returning a cpu number,
because that's what the callers want.

It could be made more efficient by passing the previous cpu rather than
an index, but that would be more invasive to the callers.

[backporting for 3.18: only two callers exist, otherwise no change.
 The same warning shows up for "!cpumask_of_node()", and I thought
 about just addressing the warning, but using the whole fix seemed
 better in the end as one of the two callers also lacks the error
 handling]

      modpost: don't emit section mismatch warnings for compiler optimizations · 62011a96
      Paul Gortmaker authored 
      commit 4a3893d0 upstream.

Currently an allyesconfig build [gcc-4.9.1] can generate the following:

   WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in
   reference from the function cpumask_empty.constprop.3() to the
   variable .init.data:nmi_ipi_mask

which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c.

Normally we would not see a symbol entry for cpumask_empty since it is:

	static inline bool cpumask_empty(const struct cpumask *srcp)

however in this case, the variant of the symbol gets emitted when GCC does
constant propagation optimization.

Fix things up so that any locally optimized constprop variants don't warn
when accessing variables that live in the __init sections.

      modpost: expand pattern matching to support substring matches · 0acdf438
      Paul Gortmaker authored 
      commit 09c20c03 upstream.

Currently the match() function supports a leading * to match any
prefix and a trailing * to match any suffix.  However there currently
is not a combination of both that can be used to target matches of
whole families of functions that share a common substring.

Here we expand the *foo and foo* match to also support *foo* with
the goal of targeting compiler generated symbol names that contain
strings like ".constprop." and ".isra."

      scsi: advansys: remove #warning message · 5ef34699
      Arnd Bergmann authored 
      The advansys driver was converted to the proper DMA API in linux-4.2, but
the 3.18-stable kernel still warns about this:

drivers/scsi/advansys.c:71:2: warning: #warning this driver is still not properly converted to the DMA API [-Wcpp]

The warning clearly is not helpful in 3.18 any more, it just clutters up
the build log. This removes the warning instead, and clarifies the
comment above it.

      i2o: hide unsafe ioctl on 64-bit · 85741f96

      We get a warning about a broken pointer conversion on 64-bit architectures:

         ((void __user *)sg[j].addr_bus, sg_list[j].virt,
          ^

This has clearly never worked right, so we can add an #ifdef around the code.
The driver was moved to staging in linux-4.0 and finally removed in 4.2,
so upstream does not have a fix for it.

The driver originally got this mostly right, though probably by accident.

The problem seems to be caused by commit 83bc7692 ("MIPS: JZ4740: Use
generic irq chip") from linux-3.2, but only showed up in a defconfig
build when qi_lb60_defconfig was added in linux-3.13 and that configuration
never successfully built.

The code has changed in a number of ways before 4.4, which builds fine.
While I did not bisect the problem to a specific change, I found a simple
fix by including the obviously missing header.

pageblock_order can be (at least) an unsigned int or an unsigned long

      arm64: build vdso without libgcov · d7aebee9
      Arnd Bergmann authored 
      commit 54309784 upstream.

On a cross-toolchain without glibc support, libgcov may not be

We don't really want to link libgcov into the vdso anyway, so
this patch just disables GCOV in the vdso directory, just as
we do for most other architectures.

      mISDN: avoid arch specific __builtin_return_address call · 66ef39fe
      Arnd Bergmann authored

Not all architectures are able to call __builtin_return_address().
On ARM, the mISDN code produces this warning:

In a lot of cases, this is relatively easy to work around by
passing the value of __builtin_return_address(0) from the
callers into the functions that want it. One exception is
the indirect 'open' function call in struct isac_hw. While it
would be possible to fix this as well, this patch only addresses
the other callers properly and lets this one return the direct
parent function, which should be good enough.

Apparently, the problem is related to the fact that the value 0xff00,
when used as a 16-bit number, is negative and passed into bitwise
operands of the generic byte swapping code.

Marking the input argument as unsigned in both technically correct
and avoids the warning.

      IB/ehca: fix maybe-uninitialized warnings · 704ee89e
      Arnd Bergmann authored 
      The driver causes two warnings about possibly uninitialized variables:

drivers/infiniband/hw/ehca/ehca_mrmw.c: In function 'ehca_set_pagebuf':
drivers/infiniband/hw/ehca/ehca_mrmw.c:1908:4: warning: 'prev_pgaddr' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/infiniband/hw/ehca/ehca_mrmw.c:1924:14: note: 'prev_pgaddr' was declared here
drivers/infiniband/hw/ehca/ehca_mrmw.c: In function 'ehca_reg_mr':
drivers/infiniband/hw/ehca/ehca_mrmw.c:2430:5: warning: 'hret' may be used uninitialized in this function [-Wmaybe-uninitialized]

The first one is definitely a false positive, the second one may or may not
be one. In both cases, adding an intialization is the safe and easy
workaround.

The driver was removed in mainline in commit e581d111
("staging/rdma: remove deprecated ehca driver"), in linux-4.6.
In 4.4, the file is located in drivers/staging/rdma/ehca/ehca_mrmw.c,
and the fix still applies.
