15      Minimum allowable password length.

22      Trade binary size versus speed for the md5sum algorithm.

31config FEATURE_FAST_TOP
32    bool "Faster /proc scanning code (+100 bytes)"
33    default y
34    help
35      This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
36      but code size is slightly bigger.
37
38config FEATURE_ETC_NETWORKS
39    bool "Support for /etc/networks"
40    default n
41    help
42      Enable support for network names in /etc/networks. This is
43      a rarely used feature which allows you to use names
44      instead of IP/mask pairs in route command.
45
46config FEATURE_USE_TERMIOS
47    bool "Use termios to manipulate the screen"
48    default y
49    depends on MORE || TOP || POWERTOP
50    help
51      This option allows utilities such as 'more' and 'top' to determine
52      the size of the screen. If you leave this disabled, your utilities
53      that display things on the screen will be especially primitive and
54      will be unable to determine the current screen size, and will be
55      unable to move the cursor.
56
57config FEATURE_EDITING
58    bool "Command line editing"
59    default y
60    help
61      Enable line editing (mainly for shell command line).
62
63config FEATURE_EDITING_MAX_LEN
64    int "Maximum length of input"
65    range 128 8192
66    default 1024
67    depends on FEATURE_EDITING
68    help
69      Line editing code uses on-stack buffers for storage.
70      You may want to decrease this parameter if your target machine
71      benefits from smaller stack usage.
72
73config FEATURE_EDITING_VI
74    bool "vi-style line editing commands"
75    default n
76    depends on FEATURE_EDITING
77    help
78      Enable vi-style line editing. In shells, this mode can be
79      turned on and off with "set -o vi" and "set +o vi".

81config FEATURE_EDITING_HISTORY
82    int "History size"
83    range 0 99999
84    default 255
85    depends on FEATURE_EDITING
86    help
87      Specify command history size.
88
89config FEATURE_EDITING_SAVEHISTORY
90    bool "History saving"
91    default y
92    depends on FEATURE_EDITING
93    help
94      Enable history saving in shells.
95
96config FEATURE_TAB_COMPLETION
97    bool "Tab completion"
98    default y
99    depends on FEATURE_EDITING
100    help
101      Enable tab completion.
102
103config FEATURE_USERNAME_COMPLETION
104    bool "Username completion"
105    default n
106    depends on FEATURE_TAB_COMPLETION
107    help
108      Enable username completion.
109
110config FEATURE_EDITING_FANCY_PROMPT
111    bool "Fancy shell prompts"
112    default y
113    depends on FEATURE_EDITING
114    help
115      Setting this option allows for prompts to use things like \w and
116      \$ and escape codes.
117
118config FEATURE_EDITING_ASK_TERMINAL
119    bool "Query cursor position from terminal"
120    default n
121    depends on FEATURE_EDITING
122    help
123      Allow usage of "ESC [ 6 n" sequence. Terminal answers back with
124      current cursor position. This information is used to make line
125      editing more robust in some cases.
126      If you are not sure whether your terminals respond to this code
127      correctly, or want to save on code size (about 400 bytes),
128      then do not turn this option on.
129
130config FEATURE_NON_POSIX_CP
131    bool "Non-POSIX, but safer, copying to special nodes"
132    default y
133    help
134      With this option, "cp file symlink" will delete symlink
135      and create a regular file. This does not conform to POSIX,
136      but prevents a symlink attack.
137      Similarly, "cp file device" will not send file's data
138      to the device.
139
140config FEATURE_VERBOSE_CP_MESSAGE
141    bool "Give more precise messages when copy fails (cp, mv etc)"
142    default n
143    help
144      Error messages with this feature enabled:
145        $ cp file /does_not_exist/file
146        cp: cannot create '/does_not_exist/file': Path does not exist
147        $ cp file /vmlinuz/file
148        cp: cannot stat '/vmlinuz/file': Path has non-directory component
149      If this feature is not enabled, they will be, respectively:
150        cp: cannot create '/does_not_exist/file': No such file or directory
151        cp: cannot stat '/vmlinuz/file': Not a directory
152      This will cost you ~60 bytes.
153
154config FEATURE_COPYBUF_KB
155    int "Copy buffer size, in kilobytes"
156    range 1 1024
157    default 4
158    help
159      Size of buffer used by cp, mv, install etc.
160      Buffers which are 4 kb or less will be allocated on stack.
161      Bigger buffers will be allocated with mmap, with fallback to 4 kb
162      stack buffer if mmap fails.
163
164config MONOTONIC_SYSCALL
165    bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
166    default n
167    depends on PLATFORM_LINUX
168    help
169      Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
170      time intervals (time, ping, traceroute etc need this).
171      Probably requires Linux 2.6+. If not selected, gettimeofday
172      will be used instead (which gives wrong results if date/time
173      is reset).
174
175config IOCTL_HEX2STR_ERROR
176    bool "Use ioctl names rather than hex values in error messages"
177    default y
178    help
179      Use ioctl names rather than hex values in error messages
180      (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
181      saves about 1400 bytes.
182
183config FEATURE_HWIB
184    bool "Support infiniband HW"
185    default y
186    help
187      Support for printing infiniband addresses in
188      network applets.
