      arm64: fix alignment padding in assembly code · aeed41a9
      Marc Zyngier authored
      An interesting effect of using the generic version of linkage.h
      is that the padding is defined in terms of x86 NOPs, which can have
      even more interesting effects when the assembly code looks like this:
      
      ENTRY(func1)
      	mov	x0, xzr
      ENDPROC(func1)
      	// fall through
      ENTRY(func2)
      	mov	x0, #1
      	ret
      ENDPROC(func2)
      
      Admittedly, the code is not very nice. But having code from another
      architecture doesn't look completely sane either.
      
      The fix is to add arm64's version of linkage.h, which causes the insertion
      of proper AArch64 NOPs.

      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
      
      * The python binding needs to link with libtraceevent and to initialize
        the 'page_size' variable so that mmaping works again.
      
      * The callchain folding character that appears on the TUI just before
        the overhead had disappeared due to recent changes, add it back.
      
      * Intel PEBS in VT-x context uses the DS address as a guest linear address,
        even though its programmed by the host as a host linear address. This either
        results in guest memory corruption and or the hardware faulting and 'crashing'
        the virtual machine.  Therefore we have to disable PEBS on VT-x enter and
        re-enable on VT-x exit, enforcing a strict exclude_guest.
      
        Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.

        samples in JITted code, where we don't have an ELF file, just an special

      MODSIGN: Move the magic string to the end of a module and eliminate the search · caabe240
      David Howells authored
      Emit the magic string that indicates a module has a signature after the
      signature data instead of before it.  This allows module_sig_check() to
      be made simpler and faster by the elimination of the search for the
      magic string.  Instead we just need to do a single memcmp().
      
      This works because at the end of the signature data there is the
      fixed-length signature information block.  This block then falls
      immediately prior to the magic number.
      
      From the contents of the information block, it is trivial to calculate
      the size of the signature data and thus the size of the actual module
      data.

      hold task->mempolicy while numa_maps scans. · 9e781440
      KAMEZAWA Hiroyuki authored
        /proc/<pid>/numa_maps scans vma and show mempolicy under
        mmap_sem. It sometimes accesses task->mempolicy which can
        be freed without mmap_sem and numa_maps can show some
        garbage while scanning.
      
      This patch tries to take reference count of task->mempolicy at reading
      numa_maps before calling get_vma_policy(). By this, task->mempolicy
      will not be freed until numa_maps reaches its end.
      
      V2->v3
        -  updated comments to be more verbose.
        -  removed task_lock() in numa_maps code.
      V1->V2
        -  access task->mempolicy only once and remember it.  Becase kernel/exit.c
           can overwrite it.

      Thierry reported that the "iron out" patch for isolate_freepages_block()
      had problems due to the strict check being too strict with "mm:
      compaction: Iron out isolate_freepages_block() and
      isolate_freepages_range() -fix1".  It's possible that more pages than
      necessary are isolated but the check still fails and I missed that this
      fix was not picked up before RC1.  This same problem has been identified
      in 3.7-RC1 by Tony Prisk and should be addressed by the following patch.

      pidns: remove recursion from free_pid_ns() · bbc2e3ef
      Cyrill Gorcunov authored
      free_pid_ns() operates in a recursive fashion:
      
      free_pid_ns(parent)
        put_pid_ns(parent)
          kref_put(&ns->kref, free_pid_ns);
            free_pid_ns
      
      thus if there was a huge nesting of namespaces the userspace may trigger
      avalanche calling of free_pid_ns leading to kernel stack exhausting and a
      panic eventually.
      
      This patch turns the recursion into an iterative loop.
      
      Based on a patch by Andrew Vagin.

      kernel/sys.c: fix stack memory content leak via UNAME26 · 2702b152
      Kees Cook authored
      Calling uname() with the UNAME26 personality set allows a leak of kernel
      stack contents.  This fixes it by defensively calculating the length of
      copy_to_user() call, making the len argument unsigned, and initializing
      the stack buffer to zero (now technically unneeded, but hey, overkill).

      linux/coredump.h needs asm/siginfo.h · 1d46e232
      Richard Weinberger authored
      Commit 5ab1c309 ("coredump: pass siginfo_t* to do_coredump() and
      below, not merely signr") added siginfo_t to linux/coredump.h but forgot
      to include asm/siginfo.h.  This breaks the build for UML/i386.  (And any
      other arch where asm/siginfo.h is not magically preincluded...)

      remap_file_pages: correctly handle the case of a NULL vm_ops pointer · deb521c4
      Linus Torvalds authored
      In commit 0b173bc4 ("mm: kill vma flag VM_CAN_NONLINEAR") we
      replaced the VM_CAN_NONLINEAR test with checking whether the mapping has
      a '->remap_pages()' vm operation, but there is no guarantee that there
      it even has a vm_ops pointer at all.
      
      Add the appropriate test for NULL vm_ops.

      kbuild: Fix module signature generation · b05e585d
      Linus Torvalds authored
      Rusty had clearly not actually tested his module signing changes that I
      (trustingly) applied as commit e2a666d5 ("kbuild: sign the modules
      at install time"). That commit had multiple bugs:
      
       - using "${#VARIABLE}" to get the number of characters in a shell
         variable may look clever, but it's locale-dependent: it returns the
         number of *characters*, not bytes. And we do need bytes.
      
         So don't use "${#..}" expansion, do the stupid "wc -c" thing instead
         (where "c" stands for "bytes", not "characters", despite the letter.
      
       - Rusty had confused "siglen" and "signerlen", and his conversion
         didn't set "signerlen" at all, and incorrectly set "siglen" to the
         size of the signer, not the size of the signature.
      
      End result: the modified sign-file script did create something that
      superficially *looked* like a signature, but didn't actually work at
      all, and would fail the signature check. Oops.
      
      Tssk, tssk, Rusty.
      
      But Rusty was definitely right that this whole thing should be rewritten
      in perl by somebody who has the perl-fu to do so.  That is not me,
      though - I'm just doing an emergency fix for the shell script.

      xen: Fix annoying compile-time warning · 16757372
      Linus Torvalds authored
      Commit cb6b6df1 ("xen/pv-on-hvm kexec: add quirk for Xen 3.4 and
      shutdown watches.") added the xen_strict_xenbus_quirk() function with an
      old K&R-style declaration without proper typing, causing gcc to rightly
      complain:
      
        drivers/xen/xenbus/xenbus_xs.c:628:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
      
      because we really don't live in caves using stone-age tools any more,
      and the kernel has always used properly typed ANSI C function
      declarations.
      
      So if a function doesn't take arguments, we tell the compiler so
      explicitly by adding the proper "void" in the prototype.
      
      I'm sure there are tons of other examples of this kind of stuff in the
      tree, but this is the one that hits my workstation config, so..

        There are the usual UABI header file movements, and we finally are now

        wait for after some other trees got merged into yours during the big
        3.7-rc1 merge window.)
      
        Other than that, nothing major, just a number of bugfixes and new
        device ids.  It turns out that almost all of the usb-serial drivers
        had bugs in how they were handling their internal data, leaking
        memory, hence all of those fixups.
