ve/pidns: Use proper ns in sys_getppid() struct nsproxy::pid_ns is the pidns for children processes in fact, so use task_active_pid_ns() instead. The struct field got already renamed in ms by commit c2b1df2eb429 "(Rename nsproxy.pid_ns to nsproxy.pid_ns_for_children"). The problem appears only in case a process has done unshare(CLONE_NEWPID) and after that called sys_getppid(). https://jira.sw.ru/browse/PSBM-121530 Fixes: 762f3e6a33f3 ("ve: Replace 0 ppid with 1 (workaround for bad utils)") Signed-off-by: Konstantin Khorenko <khore...@virtuozzo.com> --- kernel/sys.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/sys.c b/kernel/sys.c index 2ce16c7..8687707 100644 --- a/kernel/sys.c +++ b/kernel/sys.c @@ -1231,7 +1231,7 @@ SYSCALL_DEFINE0(getppid) int pid; rcu_read_lock(); - pid = ve_task_ppid_nr_ns(current, current->nsproxy->pid_ns); + pid = ve_task_ppid_nr_ns(current, task_active_pid_ns(current)); rcu_read_unlock(); return pid; _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
