| config PASSWORD_MINLEN |
| int "Minimum password length" |
| default 6 |
| range 5 32 |
| help |
| Minimum allowable password length. |
| |
| config MD5_SIZE_VS_SPEED |
| int " MD5: Trade Bytes for Speed" |
| default 2 |
| range 0 3 |
| help |
| Trade binary size versus speed for the md5sum algorithm. |
| Approximate values running uClibc and hashing |
| linux-2.4.4.tar.bz2 were: |
| user times (sec) text size (386) |
| 0 (fastest) 1.1 6144 |
| 1 1.4 5392 |
| 2 3.0 5088 |
| 3 (smallest) 5.1 4912 |
| |
| config FEATURE_FAST_TOP |
| bool "Faster /proc scanning code (+100 bytes)" |
| default n |
| help |
| This option makes top (and ps) ~20% faster (or 20% less CPU hungry), |
| but code size is slightly bigger. |
| |
| config FEATURE_ETC_NETWORKS |
| bool "Support for /etc/networks" |
| default n |
| help |
| Enable support for network names in /etc/networks. This is |
| a rarely used feature which allows you to use names |
| instead of IP/mask pairs in route command. |
| |
| config FEATURE_EDITING |
| bool "Command line editing" |
| default n |
| help |
| Enable line editing (mainly for shell command line). |
| |
| config FEATURE_EDITING_MAX_LEN |
| int "Maximum length of input" |
| range 128 8192 |
| default 1024 |
| depends on FEATURE_EDITING |
| help |
| Line editing code uses on-stack buffers for storage. |
| You may want to decrease this parameter if your target machine |
| benefits from smaller stack usage. |
| |
| config FEATURE_EDITING_VI |
| bool "vi-style line editing commands" |
| default n |
| depends on FEATURE_EDITING |
| help |
| Enable vi-style line editing. In shells, this mode can be |
| turned on and off with "set -o vi" and "set +o vi". |
| |
| config FEATURE_EDITING_HISTORY |
| int "History size" |
| range 0 99999 |
| default 15 |
| depends on FEATURE_EDITING |
| help |
| Specify command history size. |
| |
| config FEATURE_EDITING_SAVEHISTORY |
| bool "History saving" |
| default n |
| depends on ASH && FEATURE_EDITING |
| help |
| Enable history saving in ash shell. |
| |
| config FEATURE_TAB_COMPLETION |
| bool "Tab completion" |
| default n |
| depends on FEATURE_EDITING |
| help |
| Enable tab completion. |
| |
| config FEATURE_USERNAME_COMPLETION |
| bool "Username completion" |
| default n |
| depends on FEATURE_TAB_COMPLETION |
| help |
| Enable username completion. |
| |
| config FEATURE_EDITING_FANCY_PROMPT |
| bool "Fancy shell prompts" |
| default n |
| depends on FEATURE_EDITING |
| help |
| Setting this option allows for prompts to use things like \w and |
| \$ and escape codes. |
| |
| config FEATURE_COPYBUF_KB |
| int "Copy buffer size, in kilobytes" |
| range 1 1024 |
| default 4 |
| help |
| Size of buffer used by cp, mv, install etc. |
| Buffers which are 4 kb or less will be allocated on stack. |
| Bigger buffers will be allocated with mmap, with fallback to 4 kb |
| stack buffer if mmap fails. |
| |
| config MONOTONIC_SYSCALL |
| bool "Use clock_gettime(CLOCK_MONOTONIC) syscall" |
| default y |
| help |
| Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring |
| time intervals (time, ping, traceroute etc need this). |
| Probably requires Linux 2.6+. If not selected, gettimeofday |
| will be used instead (which gives wrong results if date/time |
| is reset). |
| |
| config IOCTL_HEX2STR_ERROR |
| bool "Use ioctl names rather than hex values in error messages" |
| default y |
| help |
| Use ioctl names rather than hex values in error messages |
| (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this |
| saves about 1400 bytes. |
