      signal: unconditionally leave the frozen state in ptrace_stop() · 05b28926
      Roman Gushchin authored 
      Alex Xu reported a regression in strace, caused by the introduction of
the cgroup v2 freezer. The regression can be reproduced by stracing
the following simple program:

  #include <unistd.h>

  int main() {
      write(1, "a", 1);
      return 0;
  }

An attempt to run strace ./a.out leads to the infinite loop:
  [ pre-main omitted ]
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  write(1, "a", 1)                        = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
  [ repeats forever ]

The problem occurs because the traced task leaves ptrace_stop()
(and the signal handling loop) with the frozen bit set. So let's
call cgroup_leave_frozen(true) unconditionally after sleeping
in ptrace_stop().

With this patch applied, strace works as expected:
  [ pre-main omitted ]
  write(1, "a", 1)                        = 1
  exit_group(0)                           = ?
  +++ exited with 0 +++

      ia64: Make sure that we have a mmiowb function real early · 8a635ffb
      Tony Luck authored 
      Generic kernels feed many operation through the "machvec" logic to get
the correct form of the operation for the current system.  "mmiowb()" is
one of those operations.

Although machvec is initialized very early in boot, it isn't early
enough for a recent upstream kernel change that added mmiowb to the
spin_unlock() path.

Statically initialize the mmiowb field of machvec so that we won't die
with a call through a NULL pointer.  This should be safe because we do
the real initialization of machvec before bringing up any addtional CPUs
or doing any I/O.

Fixes: 49ca6462 ("ia64/mmiowb: Add unconditional mmiowb() to arch_spin_unlock()")

  across server reboots. We've been using a usermode_helper upcall for
  that, but it's tough to run those with the right namespaces, so a
  daemon is much friendlier to container use cases.

  Trond fixed nfsd's handling of user credentials in user namespaces. He
  also contributed patches that allow containers to support different
  sets of NFS protocol versions.

  The only remaining container bug I'm aware of is that the NFS reply
  cache is shared between all containers. If anyone's aware of other
  gaps in our container support, let me know.

  The rest of this is miscellaneous bugfixes"
