Re: [PATCH 0/7][RFC] pid: changes to support audit

These are a number of patches inspired by ebiederman's container work that were included by me 2013-08-20 as the patchset: RFC: steps to make audit pid namespace-safe They have been seperated out for the pid maintainer since there are no direct dependencies from the audit pid namespace patchset with the exception of: pid: get pid_t ppid of task in init_pid_ns Andrew, are you willing to adopt these? In particular, there is discussion around read-only task_struct::pid here: https://lkml.org/lkml/2013/12/16/552 Richard Guy Briggs (7): pid: change task_struct::pid to read-only compiler: CONST_CAST makes writing const vars easier and obvious pid: use the CONST_CAST macro instead to write to const task_struct::pid pid: modify task_tgid_nr to work without task->tgid. pid: rewrite task helper function is_global_init() avoiding task->pid pid: mark struct task const in helper functions pid: get pid_t ppid of task in init_pid_ns arch/x86/kernel/process.c | 2 +- fs/exec.c | 2 +- include/linux/compiler.h | 8 ++++++ include/linux/sched.h | 60 +++++++++++++++++++++++++++++--------------- kernel/fork.c | 5 ++- kernel/pid.c | 4 +- 6 files changed, 54 insertions(+), 27 deletions(-)
