  20           Trade binary size versus speed for the md5sum algorithm.

  31         default y
  32         help
  33           This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
  34           but code size is slightly bigger.
  35
  36 config BUSYBOX_CONFIG_FEATURE_ETC_NETWORKS
  37         bool "Support for /etc/networks"
  38         default n
  39         help
  40           Enable support for network names in /etc/networks. This is
  41           a rarely used feature which allows you to use names
  42           instead of IP/mask pairs in route command.

  45         bool "Command line editing"
  46         default y

  48           Enable line editing (mainly for shell command line).

  54         depends on BUSYBOX_CONFIG_FEATURE_EDITING
  55         help
  56           Line editing code uses on-stack buffers for storage.
  57           You may want to decrease this parameter if your target machine
  58           benefits from smaller stack usage.
  59
  60 config BUSYBOX_CONFIG_FEATURE_EDITING_VI
  61         bool "vi-style line editing commands"
  62         default n
  63         depends on BUSYBOX_CONFIG_FEATURE_EDITING
  64         help
  65           Enable vi-style line editing. In shells, this mode can be
  66           turned on and off with "set -o vi" and "set +o vi".

 100         depends on BUSYBOX_CONFIG_FEATURE_EDITING
 101         help
 102           Setting this option allows for prompts to use things like \w and
 103           \$ and escape codes.
 104
 105 config BUSYBOX_CONFIG_FEATURE_EDITING_ASK_TERMINAL
 106         bool "Query cursor position from terminal"

 109         help
 110           Allow usage of "ESC [ 6 n" sequence. Terminal answers back with
 111           current cursor position. This information is used to make line
 112           editing more robust in some cases.
 113           If you are not sure whether your terminals respond to this code
 114           correctly, or want to save on code size (about 400 bytes),
 115           then do not turn this option on.
 116
 117 config BUSYBOX_CONFIG_FEATURE_NON_POSIX_CP
 118         bool "Non-POSIX, but safer, copying to special nodes"
 119         default y
 120         help
 121           With this option, "cp file symlink" will delete symlink
 122           and create a regular file. This does not conform to POSIX,
 123           but prevents a symlink attack.
 124           Similarly, "cp file device" will not send file's data
 125           to the device.
 126
 127 config BUSYBOX_CONFIG_FEATURE_VERBOSE_CP_MESSAGE
 128         bool "Give more precise messages when copy fails (cp, mv etc)"
 129         default n
 130         help
 131           Error messages with this feature enabled:
 132             $ cp file /does_not_exist/file
 133             cp: cannot create '/does_not_exist/file': Path does not exist
 134             $ cp file /vmlinuz/file
 135             cp: cannot stat '/vmlinuz/file': Path has non-directory component
 136           If this feature is not enabled, they will be, respectively:
 137             cp: cannot create '/does_not_exist/file': No such file or directory
 138             cp: cannot stat '/vmlinuz/file': Not a directory
 139           This will cost you ~60 bytes.

 141 config BUSYBOX_CONFIG_FEATURE_COPYBUF_KB
 142         int "Copy buffer size, in kilobytes"
 143         range 1 1024

 145         help
 146           Size of buffer used by cp, mv, install etc.
 147           Buffers which are 4 kb or less will be allocated on stack.
 148           Bigger buffers will be allocated with mmap, with fallback to 4 kb
 149           stack buffer if mmap fails.
 150
 151 config BUSYBOX_CONFIG_MONOTONIC_SYSCALL
 152         bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
 153         default n
 154         help
 155           Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
 156           time intervals (time, ping, traceroute etc need this).
 157           Probably requires Linux 2.6+. If not selected, gettimeofday
 158           will be used instead (which gives wrong results if date/time
 159           is reset).
 160
 161 config BUSYBOX_CONFIG_IOCTL_HEX2STR_ERROR
 162         bool "Use ioctl names rather than hex values in error messages"
 163         default y
 164         help
 165           Use ioctl names rather than hex values in error messages
 166           (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
 167           saves about 1400 bytes.
 168
 169 config BUSYBOX_CONFIG_FEATURE_HWIB
 170         bool "Support infiniband HW"
 171         default n

 174           network applets.
