      LSM: Revive security_task_alloc() hook and per "struct task_struct" security blob. · e4e55b47
      Tetsuo Handa authored
      We switched from "struct task_struct"->security to "struct cred"->security
      in Linux 2.6.29. But not all LSM modules were happy with that change.
      TOMOYO LSM module is an example which want to use per "struct task_struct"
      security blob, for TOMOYO's security context is defined based on "struct
      task_struct" rather than "struct cred". AppArmor LSM module is another
      example which want to use it, for AppArmor is currently abusing the cred
      a little bit to store the change_hat and setexeccon info. Although
      security_task_free() hook was revived in Linux 3.4 because Yama LSM module
      wanted to release per "struct task_struct" security blob,
      security_task_alloc() hook and "struct task_struct"->security field were
      not revived. Nowadays, we are getting proposals of lightweight LSM modules
      which want to use per "struct task_struct" security blob.
      
      We are already allowing multiple concurrent LSM modules (up to one fully
      armored module which uses "struct cred"->security field or exclusive hooks
      like security_xfrm_state_pol_flow_match(), plus unlimited number of
      lightweight modules which do not use "struct cred"->security nor exclusive
      hooks) as long as they are built into the kernel. But this patch does not
      implement variable length "struct task_struct"->security field which will
      become needed when multiple LSM modules want to use "struct task_struct"->
      security field. Although it won't be difficult to implement variable length
      "struct task_struct"->security field, let's think about it after we merged
      this patch.
