file for /boot +.Sh DESCRIPTION +The file +.Pa /boot.cfg +is used to alter the behaviour of the standard boot loader described in +.Xr boot 8 . +Configuration changes include setting the timeout, choosing a console device, +altering the banner text and displaying a menu allowing boot commands to be +easily chosen. +If a +.Nm +file is not present, the system will boot as normal. +.Ss FILE FORMAT +The format of the file is a series of lines containing keyword/value pairs +separated by an equals sign +.Pq Sq = . +There should be no whitespace surrounding the equals sign. +Lines beginning with a hash +.Pq Sq # +are comments and will be ignored. +.Pp +Some keywords can be present multiple times in the file to define additional +items. +Such keywords are noted below. +.Pp +.Bl -tag -width timeout +.It Sy banner +(may be present multiple times) +The text from banner lines is displayed instead of the standard welcome text +by the boot loader. +Up to 10 lines can be defined. +No special character sequences are recognised, so to specify a blank line, a +banner line with no value should be given. +.It Sy clear +If nonzero, clear the screen before printing the banner. +If zero, do not clear the screen (the default). +.It Sy consdev +Changes the console device to that specified in the value. +Valid values are any of those that could be specified at the normal boot +prompt with the consdev command. +.It Sy default +Used to specify the default menu item which will be chosen in the case of +Return being pressed or the timeout timer reaching zero. +The value is the number of the menu item as displayed. +As described above, the menu items are counted from 1 in the order listed in +.Nm . +If not specified, the default value will be option 1, i.e. the first item. +.It Sy format +Changes how the menu options are displayed. +Should be set to one of +.Sq a +for automatic, +.Sq l +for letters and +.Sq n +for numbers. +If set to automatic (the default), menu options will be displayed numerically +unless there are more than 9 options and the timeout is greater than zero. +If there are more than 9 options with a timeout greater than zero and +the format is set to number, only the first 9 options will be available. +.It Sy load +Used to load kernel modules, which will be passed on to the kernel for +initialization during early boot. +The argument is either the complete path and file name of the module to be +loaded, or a symbolic module name. +When the argument is not an absolute path, the boot loader will first +attempt to load +.Pa /stand/\*[Lt]machine\*[Gt]/\*[Lt]kernel_version\*[Gt]/modules/\*[Lt]name\*[Gt]/\*[Lt]name\*[Gt].kmod . +If that file does not exist, it will then attempt to load +.Pa /\*[Lt]name\*[Gt] . +May be used as many times as needed. +.It Sy menu +(may be present multiple times) +Used to define a menu item to be displayed to the end-user at boot time +which allows a series of boot commands to be run without further typing. +The value consists of the required menu text, followed by a colon +.Pq Sq \&: +and then the desired command(s). +Multiple commands can be specified separated by a semi-colon. +If the specified menu text is empty +(the colon appears immediately after the equals sign), +then the displayed menu text is the same as the command. +For example: +.Bd -literal +menu=Boot normally:boot +menu=Boot single-user:boot -s +menu=Boot with module foo:load /foo.kmod;boot +menu=Boot with serial console:consdev com0;boot +menu=:boot hd1a:netbsd -as +.Ed +.Pp +Each menu item will be prefixed by an ascending number when displayed, +i.e. the order in the +.Nm +file is important. +.Pp +Each command is executed just as though the user had typed it in +and so can be any valid command that would be accepted at the +normal boot prompt. +In addition, +.Dq Ic prompt +can be used to drop to the normal boot prompt. +.It Sy timeout +If the value is greater than zero, this specifies the time in seconds +that the boot loader will wait for the end-user to choose a menu item. +During the countdown period, they may press Return to choose the default +option or press a number key corresponding to a menu option. +If any other key is pressed, the countdown will stop and the user will be +prompted to choose a menu option with no further time limit. +If the timeout value is set to zero, the default option will be booted +immediately. +If the timeout value is negative or is not a number, there will be no +time limit for the user to choose an option. +.It Sy userconf +Passes a +.Xr userconf 4 +command to the kernel at boot time . +.It Sy rndseed +Takes the path to a random-seed file as written by the +.Fl S +flag to +.Xr rndctl 8 +as an argument. +This file is used to seed the kernel entropy pool +.Xr rnd 9 +very early in kernel startup, so that high quality randomness is +available to all kernel modules. +This argument should be supplied +before any +.Dq Ic load +commands that may load executable modules. +.El +.Sh EXAMPLES +Here is an example +.Nm +file: +.Bd -literal -offset indent +banner=Welcome to NetBSD +banner==================

It exists purely to + * allow the _COPYS macro to be reused, but because it + * requires this long attempt to explain it, I'm starting + * to doubt the value of that. + * + * Part of the expansion of the _COPYS macro below are loops + * that copy four words or one word at a time, performing shifts + * to get data to line up correctly in the destination buffer. + * + * The _COPYS macro is used when copying backwards, as well + * as forwards. The 4-word loop always loads into %t1, %t2, %t3, + * and %t4 in that order. This means that when copying forward, + * %t1 will have the word from the lowest address, and %t4 will + * have the word from the highest address. When copying + * backwards, the opposite is true. + * + * The shift instructions need pairs of registers with adjacent + * words, with the register containing the word from the lowest + * address *always* coming first. It is this assymetry that + * gives rise to this macro - depending on which direction + * we're copying in, these ordered pairs are different. + * + * Fortunately, we can compute those register numbers at compile + * time, and assemble them manually into a shift instruction. + * That's what this macro does. + * + * This macro takes two arguments. n ranges from 0 to 3 and + * is the "shift number", i.e., n = 0 means we're doing the + * shift for what will be the first store. + * + * m is the displacement multiplier from the _COPYS macro call. + * This is 1 for a forward copy and -1 for a backwards copy. + * So, the ((m + 1) / 2) term yields 0 for a backwards copy and + * 1 for a forward copy, and the ((m - 1) / 2) term yields + * 0 for a forward copy, and -1 for a backwards copy. + * These terms are used to discriminate the register computations + * below. + * + * When copying forward, then, the first register used with + * the first vshd will be 19 + (3 - ((0 - 1) & 3)), or %t4, + * which matches _COPYS' requirement that the word last loaded + * be in %t4. The first register used for the second vshd + * will then "wrap" around to 19 + (3 - ((1 - 1) & 3)), or %t1. + * And so on to %t2 and %t3. + * + * When copying forward, the second register used with the first + * vshd will be (19 + (3 - ((n + 0) & 3)), or %t1. It will + * continue to be %t2, then %t3, and finally %t4. + * + * When copying backwards, the values for the first and second + * register for each vshd are reversed from the forwards case. + * (Symmetry reclaimed!)

Perhaps it has ceased to latch a shift + * register and is feeding you the same data over and over again. Perhaps + * it is not really random at all but was sold to you as such. Perhaps it + * is not actually *there* (Intel chipset RNG anyone?) but claims to be, + * and is feeding you 01010101 on every register read. + * + * However, when applied to software RNGs, the situation is quite different. + * Most software RNGs use a modern hash function or cipher as an output + * stage. The resulting bitstream assuredly *should* pass both the + * "continuous output" (no two consecutive samples identical) and + * statistical tests: if it does not, the cryptographic primitive or its + * implementation is terribly broken. + * + * There is still value to this test: it will tell you if you inadvertently + * terribly break your implementation of the software RNG. Which is a thing + * that has in fact happened from time to time, even to the careful (or + * paranoid). But it will not tell you if there is a problem with the + * _input_ to that final cryptographic primitive -- the bits that are hashed + * or the key to the cipher -- and if an adversary can find one, you're + * still toast. + * + * The situation is -- sadly -- similar with hardware RNGs that are + * certified to one of the standards such as X9.31 or SP800-90. In these + * cases the hardware vendor has hidden the actual random bitstream behind + * a hardware cipher/hash implementation that should, indeed, produce good + * quality random numbers that pass will pass this test -- whether the + * underlying bitstream is trustworthy or not. + * + * However, this test (and the COT) will still probably tell you if the + * thing fell off the bus, etc. Which is a thing that has in fact + * happened from time to time, even to the fully certified... + * + * This module does not (yet?) implement the Continuous Output Test.
