113 | help | |
114 | This kernel feature is useful for number crunching applications | |
115 | that may need to compute untrusted bytecode during their | |
116 | execution. By using pipes or other transports made available to | |
117 | the process as file descriptors supporting the read/write | |
118 | syscalls, it's possible to isolate those applications in | |
119 | their own address space using seccomp. Once seccomp is | |
120 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
121 | and the task is only allowed to execute a few safe syscalls | |
122 | defined by each seccomp mode. | |
