Not calling the function for dummy contexts will cause the context to
not be reset. During the next syscall, this will cause an error in
__audit_syscall_entry:
WARN_ON(context->context != AUDIT_CTX_UNUSED);
WARN_ON(context->name_count);
if (context->context != AUDIT_CTX_UNUSED || context->name_count) {
audit_panic("unrecoverable error in audit_syscall_entry()");
return;
}
These problematic dummy contexts are created via the following call
chain:
exit_to_user_mode_prepare
-> arch_do_signal_or_restart
-> get_signal
-> task_work_run
-> tctx_task_work
-> io_req_task_submit
-> io_issue_sqe
-> audit_uring_entry
