The following patches add the self-test for sigaltstack(SS_DISABLE) inside the signal handler, and remove the EPERM check in a sigaltstack() syscall. This is needed to make sigaltstack() compatible with swapcontext(): before using swapcontext() inside the sighandler, the sigaltstack should be disabled, or the stack will be corrupted by the subsequent signals. -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
