1da177e4 | 10 | ** The values in this file are exported to user space via |
7cc13edc EB |
11 | ** the sysctl() binary interface. Do *NOT* change the |
12 | ** numbering of any existing values here, and do not change | |
13 | ** any numbers within any one set of values. If you have to | |
93aec204 | 14 | ** redefine an existing interface, use a new number for it. |
7cc13edc EB |
15 | ** The kernel will then return -ENOTDIR to any application using |
16 | ** the old binary interface. | |
17 | ** | |
18 | ** For new interfaces unless you really need a binary number | |
19 | ** please use CTL_UNNUMBERED. | |

1018 | * | |
1019 | * The table's mode will be honoured both for sys_sysctl(2) and | |
1020 | * proc-fs access. | |
1021 | * | |
1022 | * Leaf nodes in the sysctl tree will be represented by a single file | |

1029 | * sysctl(2) can automatically manage read and write requests through |

1031 | * struct enable minimal validation of the values being written to be | |
1032 | * performed, and the mode field allows minimal authentication. | |
1033 | * | |
1034 | * More sophisticated management can be enabled by the provision of a | |
1035 | * strategy routine with the table entry. This will be called before | |
1036 | * any automatic read or write of the data is performed. | |
1037 | * | |
1038 | * The strategy routine may return: | |
1039 | * <0: Error occurred (error is passed to user process) | |
1040 | * 0: OK - proceed with automatic read or write. | |
1041 | * >0: OK - read or write has been done by the strategy routine, so | |
1042 | * return immediately. | |
1043 | * | |
1044 | * There must be a proc_handler routine for any terminal nodes | |
1045 | * mirrored under /proc/sys (non-terminals are handled by a built-in | |
1046 | * directory handler). Several default handlers are available to | |
