# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Busybox Library Tuning" 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_FANCY_KEYS bool "Additional editing keys" default n depends on FEATURE_EDITING help Enable additonal editing keys (Ctrl-E, Ctrl-U etc). Arrow keys, Home/End/Delete and Ctrl-W work even without this option. 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 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. endmenu
