      kvm: rename KVM_HINTS_DEDICATED to KVM_HINTS_REALTIME · 633711e8
      Michael S. Tsirkin authored
      KVM_HINTS_DEDICATED seems to be somewhat confusing:
      
      Guest doesn't really care whether it's the only task running on a host
      CPU as long as it's not preempted.
      
      And there are more reasons for Guest to be preempted than host CPU
      sharing, for example, with memory overcommit it can get preempted on a
      memory access, post copy migration can cause preemption, etc.
      
      Let's call it KVM_HINTS_REALTIME which seems to better
      match what guests expect.
      
      Also, the flag most be set on all vCPUs - current guests assume this.
      Note so in the documentation.

      proc: do not access cmdline nor environ from file-backed areas · 7f7ccc2c
      Willy Tarreau authored
      proc_pid_cmdline_read() and environ_read() directly access the target
      process' VM to retrieve the command line and environment. If this
      process remaps these areas onto a file via mmap(), the requesting
      process may experience various issues such as extra delays if the
      underlying device is slow to respond.
      
      Let's simply refuse to access file-backed areas in these functions.
      For this we add a new FOLL_ANON gup flag that is passed to all calls
      to access_remote_vm(). The code already takes care of such failures
      (including unmapped areas). Accesses via /proc/pid/mem were not
      changed though.
      
      This was assigned CVE-2018-1120.
      
      Note for stable backports: the patch may apply to kernels prior to 4.11
      but silently miss one location; it must be checked that no call to
      access_remote_vm() keeps zero as the last argument.

      bcache: return 0 from bch_debug_init() if CONFIG_DEBUG_FS=n · 1c1a2ee1
      Coly Li authored
      Commit 539d39eb ("bcache: fix wrong return value in bch_debug_init()")
      returns the return value of debugfs_create_dir() to bcache_init(). When
      CONFIG_DEBUG_FS=n, bch_debug_init() always returns 1 and makes
      bcache_init() failedi.
      
      This patch makes bch_debug_init() always returns 0 if CONFIG_DEBUG_FS=n,
      so bcache can continue to work for the kernels which don't have debugfs
      enanbled.
      
      Changelog:
      v4: Add Acked-by from Kent Overstreet.
      v3: Use IS_ENABLED(CONFIG_DEBUG_FS) to replace #ifdef DEBUG_FS.
      v2: Remove a warning information
      v1: Initial version.
