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_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.
