2409 | help | |
2410 | This kernel feature is useful for number crunching applications | |
2411 | that may need to compute untrusted bytecode during their | |
2412 | execution. By using pipes or other transports made available to | |
2413 | the process as file descriptors supporting the read/write | |
2414 | syscalls, it's possible to isolate those applications in | |
2415 | their own address space using seccomp. Once seccomp is | |
2416 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2417 | and the task is only allowed to execute a few safe syscalls | |
2418 | defined by each seccomp mode. | |

2425 | help |
2426 | When this is enabled, the kernel will support use of 64-bit floating | |
2427 | point registers with binaries using the O32 ABI along with the | |
2428 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2429 | 32-bit MIPS systems this support is at the cost of increasing the | |
2430 | size and complexity of the compiled FPU emulator. Thus if you are | |
2431 | running a MIPS32 system and know that none of your userland binaries | |
2432 | will require 64-bit floating point, you may wish to reduce the size | |
2433 | of your kernel & potentially improve FP emulation performance by | |
2434 | saying N here. | |
2435 | ||
06e2e882 PB |
2436 | Although binutils currently supports use of this flag the details |
2437 | concerning its effect upon the O32 ABI in userland are still being | |
2438 | worked on. In order to avoid userland becoming dependant upon current | |
2439 | behaviour before the details have been finalised, this option should | |
2440 | be considered experimental and only enabled by those working upon | |
2441 | said details. | |
