      pidns: remove recursion from free_pid_ns() · bbc2e3ef
      Cyrill Gorcunov 提交于
      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.

      linux/coredump.h needs asm/siginfo.h · 1d46e232
      Richard Weinberger 提交于
      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...)
