| 1621config SECCOMP 1622 bool 1623 prompt "Enable seccomp to safely compute untrusted bytecode" 1624 help 1625 This kernel feature is useful for number crunching applications 1626 that may need to compute untrusted bytecode during their 1627 execution. By using pipes or other transports made available to 1628 the process as file descriptors supporting the read/write 1629 syscalls, it's possible to isolate those applications in 1630 their own address space using seccomp. Once seccomp is 1631 enabled via prctl(PR_SET_SECCOMP), it cannot be disabled 1632 and the task is only allowed to execute a few safe syscalls 1633 defined by each seccomp mode. 1634 |
