13 | Minimum allowable password length. | ||

16 | niro | 816 | int "MD5: Trade Bytes for Speed" |
17 | niro | 532 | default 2 |
18 | range 0 3 | ||
19 | help | ||
20 | Trade binary size versus speed for the md5sum algorithm. | ||
21 | Approximate values running uClibc and hashing | ||
22 | linux-2.4.4.tar.bz2 were: | ||

29 | niro | 816 | config FEATURE_FAST_TOP |
30 | bool "Faster /proc scanning code (+100 bytes)" | ||
31 | default n | ||
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 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. | ||
43 | |||
44 | config FEATURE_EDITING | ||
45 | bool "Command line editing" | ||
46 | default n | ||
47 | help | ||
48 | Enable line editing (mainly for shell command line). | ||
49 | |||
50 | config FEATURE_EDITING_MAX_LEN | ||
51 | int "Maximum length of input" | ||
52 | range 128 8192 | ||
53 | default 1024 | ||
54 | depends on 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 FEATURE_EDITING_VI | ||
61 | bool "vi-style line editing commands" | ||
62 | default n | ||
63 | depends on 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". | ||
67 | |||
68 | config FEATURE_EDITING_HISTORY | ||
69 | int "History size" | ||
70 | range 0 99999 | ||
71 | default 15 | ||
72 | depends on FEATURE_EDITING | ||
73 | help | ||
74 | Specify command history size. | ||
75 | |||
76 | config FEATURE_EDITING_SAVEHISTORY | ||
77 | bool "History saving" | ||
78 | default n | ||
79 | depends on ASH && FEATURE_EDITING | ||
80 | help | ||
81 | Enable history saving in ash shell. | ||
82 | |||
83 | config FEATURE_TAB_COMPLETION | ||
84 | bool "Tab completion" | ||
85 | default n | ||
86 | depends on FEATURE_EDITING | ||
87 | help | ||
88 | Enable tab completion. | ||
89 | |||
90 | config FEATURE_USERNAME_COMPLETION | ||
91 | bool "Username completion" | ||
92 | default n | ||
93 | depends on FEATURE_TAB_COMPLETION | ||
94 | help | ||
95 | Enable username completion. | ||
96 | |||
97 | config FEATURE_EDITING_FANCY_PROMPT | ||
98 | bool "Fancy shell prompts" | ||
99 | default n | ||
100 | depends on FEATURE_EDITING | ||
101 | help | ||
102 | Setting this option allows for prompts to use things like \w and | ||
103 | \$ and escape codes. | ||
104 | |||
105 | config FEATURE_VERBOSE_CP_MESSAGE | ||
106 | bool "Give more precise messages when copy fails (cp, mv etc)" | ||
107 | default n | ||
108 | help | ||
109 | Error messages with this feature enabled: | ||
110 | $ cp file /does_not_exist/file | ||
111 | cp: cannot create '/does_not_exist/file': Path does not exist | ||
112 | $ cp file /vmlinuz/file | ||
113 | cp: cannot stat '/vmlinuz/file': Path has non-directory component | ||
114 | If this feature is not enabled, they will be, respectively: | ||
115 | cp: cannot remove '/does_not_exist/file': No such file or directory | ||
116 | cp: cannot stat '/vmlinuz/file': Not a directory | ||
117 | respectively. | ||
118 | This will cost you ~60 bytes. | ||
119 | |||
120 | config FEATURE_COPYBUF_KB | ||
121 | int "Copy buffer size, in kilobytes" | ||
122 | range 1 1024 | ||
123 | default 4 | ||
124 | help | ||
125 | Size of buffer used by cp, mv, install etc. | ||
126 | Buffers which are 4 kb or less will be allocated on stack. | ||
127 | Bigger buffers will be allocated with mmap, with fallback to 4 kb | ||
128 | stack buffer if mmap fails. | ||
129 | |||
130 | config MONOTONIC_SYSCALL | ||
131 | bool "Use clock_gettime(CLOCK_MONOTONIC) syscall" | ||
132 | default y | ||
133 | help | ||
134 | Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring | ||
135 | time intervals (time, ping, traceroute etc need this). | ||
136 | Probably requires Linux 2.6+. If not selected, gettimeofday | ||
137 | will be used instead (which gives wrong results if date/time | ||
138 | is reset). | ||
139 | |||
140 | config IOCTL_HEX2STR_ERROR | ||
141 | bool "Use ioctl names rather than hex values in error messages" | ||
142 | default y | ||
143 | help | ||
144 | Use ioctl names rather than hex values in error messages | ||
145 | (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this | ||
146 | saves about 1400 bytes. | ||
147 | |||
148 | config FEATURE_HWIB | ||
149 | bool "Support infiniband HW" | ||
150 | default y | ||
151 | help | ||
152 | Support for printing infiniband addresses in | ||
153 | network applets. | ||
