      [PATCH] setuid core dump · d6e71144
      Alan Cox 提交于
      Add a new `suid_dumpable' sysctl:
      
      This value can be used to query and set the core dump mode for setuid
      or otherwise protected/tainted binaries. The modes are
      
      0 - (default) - traditional behaviour.  Any process which has changed
          privilege levels or is execute only will not be dumped
      
      1 - (debug) - all processes dump core when possible.  The core dump is
          owned by the current user and no security is applied.  This is intended
          for system debugging situations only.  Ptrace is unchecked.
      
      2 - (suidsafe) - any binary which normally would not be dumped is dumped
          readable by root only.  This allows the end user to remove such a dump but
          not access it directly.  For security reasons core dumps in this mode will
          not overwrite one another or other files.  This mode is appropriate when
          adminstrators are attempting to debug problems in a normal environment.

      No problem to me.

      Actually the feedback I had from last time was that the SUID_ defines
      should go because its clearer to follow the numbers. They can go
      everywhere (and there are lots of places where dumpable is tested/used
      as a bool in untouched code)

      Fair comment. The patch was designed to be easy to maintain for Red Hat
      rather than for merging. Changing that field would create a gigantic
      diff because it is used all over the place.
