      um: Don't discard .text.exit section · dad22328
      Andrey Ryabinin authored
      Commit e41f501d ("vmlinux.lds: account for destructor sections")
      added '.text.exit' to EXIT_TEXT which is discarded at link time by default.
      This breaks compilation of UML:
           `.text.exit' referenced in section `.fini_array' of
           /usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o):
           defined in discarded section `.text.exit' of
           /usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o)
      
      Apparently UML doesn't want to discard exit text, so let's place all EXIT_TEXT
      sections in .exit.text.

      ubifs: Fix assertion in layout_in_gaps() · c0082e98
      Vincent Stehlé authored
      An assertion in layout_in_gaps() verifies that the gap_lebs pointer is
      below the maximum bound. When computing this maximum bound the idx_lebs
      count is multiplied by sizeof(int), while C pointers arithmetic does take
      into account the size of the pointed elements implicitly already. Remove
      the multiplication to fix the assertion.

      The address of the iovec &vq->iov[out] is not guaranteed to contain the scsi

      is more likely to contain an iovec from an immediately following command

      usercopy: avoid potentially undefined behavior in pointer math · 7329a655
      Eric Biggers authored
      check_bogus_address() checked for pointer overflow using this expression,
      where 'ptr' has type 'const void *':
      
      	ptr + n < ptr
      
      Since pointer wraparound is undefined behavior, gcc at -O2 by default
      treats it like the following, which would not behave as intended:
      
      	(long)n < 0
      
      Fortunately, this doesn't currently happen for kernel code because kernel
      code is compiled with -fno-strict-overflow.  But the expression should be
      fixed anyway to use well-defined integer arithmetic, since it could be
      treated differently by different compilers in the future or could be
      reported by tools checking for undefined behavior.

      Pull GPIO fixes from Linus Walleij:
       "Here are a few GPIO fixes for v4.8.
      
        I was expecting some fallout from the new chardev rework but nothing
        like that turned up att all.  Instead a Kconfig confusion that I think
        I have finally nailed, then some ordinary driver noise and trivia.
      
        This fixes a Kconfig issue with UM: when I made GPIOLIB available to
        all archs, that included UM, but the OF part of GPIOLIB requires
        HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO.
      
        This in turn exposed the fact that a few GPIO drivers were implicitly
        assuming OF_GPIO as their dependency but instead depended on OF alone
        (the typical problem being a pointer inside gpio_chip not existing
        unless OF_GPIO is selected) and then UM would fail to compile with
        these drivers instead.  Then I lost patience and made any GPIO driver
        depending on just OF depend on OF_GPIO instead, that is certainly what
        they meant and the only thing that makes sense anyway.  GPIO with just
        OF but !OF_GPIO does not make sense.
      
        Also a fix for the max730x driver data pointer, and a minor comment
        fix for the GPIO tools"

      parisc: Fix order of EREFUSED define in errno.h · 3eb53b20
      Helge Deller authored
      When building gccgo in userspace, errno.h gets parsed and the go include file
      sysinfo.go is generated.
      
      Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED
      is defined later on in errno.h, this leads to go complaining that EREFUSED
      isn't defined yet.
      
      Fix this trivial problem by moving the define of EREFUSED down after
      ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

      Make the hardened user-copy code depend on having a hardened allocator · 6040e576
      Linus Torvalds authored
      The kernel test robot reported a usercopy failure in the new hardened
      sanity checks, due to a page-crossing copy of the FPU state into the
      task structure.
      
      This happened because the kernel test robot was testing with SLOB, which
      doesn't actually do the required book-keeping for slab allocations, and
      as a result the hardening code didn't realize that the task struct
      allocation was one single allocation - and the sanity checks fail.
      
      Since SLOB doesn't even claim to support hardening (and you really
      shouldn't use it), the straightforward solution is to just make the
      usercopy hardening code depend on the allocator supporting it.

      With STRICT_MM_TYPECHECKS pte_t is a struct and the offending code
      forces a cast which ends up shifting a struct and hence the gcc warning.
      
      Note that in recent past some of the arches (aarch64, s390) made
      STRICT_MM_TYPECHECKS default, but we don't for ARC as this leads to slightly
      worse generated code, given ARC ABI definition of returning structs
      (which pte_t would become)
      
      Quoting from ARC ABI...
      
        "Results of type struct are returned in a caller-supplied temporary
        variable whose address is passed in r0.
        For such functions, the arguments are shifted so that they are
        passed in r1 and up."
      
      So
       - struct to be returned would be allocated on stack requiring extra
         code at call sites
       - callee updates stack memory to facilitate the return (vs. simple
         MOV into return reg r0)
      
      Hence STRICT_MM_TYPECHECKS is not enabled by default for ARC

      ARC: Support syscall ABI v4 · 840c054f
      Vineet Gupta authored
      The syscall ABI includes the gcc functional calling ABI since a syscall
      implies userland caller and kernel callee.
      
      The current gcc ABI (v3) for ARCv2 ISA required 64-bit data be passed in
      even-odd register pairs, (potentially punching reg holes when passing such
      values as args). This was partly driven by the fact that the double-word
      LDD/STD instructions in ARCv2 expect the register alignment and thus gcc
      forcing this avoids extra MOV at the cost of a few unused register (which we
      have plenty anyways).
      
      This however was rejected as part of upstreaming gcc port to HS. So the new
      ABI v4 doesn't enforce the even-odd reg restriction.
      
      Do note that for ARCompact ISA builds v3 and v4 are practically the same in
      terms of gcc code generation.
      
      In terms of change management, we infer the new ABI if gcc 6.x onwards
      is used for building the kernel.
      
      This also needs a stable backport to enable older kernels to work with
      new tools/user-space

      ARC: use correct offset in pt_regs for saving/restoring user mode r25 · 86147e3c
      Liav Rehana authored
      User mode callee regs are explicitly collected before signal delivery or
      breakpoint trap. r25 is special for kernel as it serves as task pointer,
      so user mode value is clobbered very early. It is saved in pt_regs where
      generally only scratch (aka caller saved) regs are saved.
      
      The code to access the corresponding pt_regs location had a subtle bug as
      it was using load/store with scaling of offset, whereas the offset was already
      byte wise correct. So fix this by replacing LD.AS with a standard LD
