|

|
Enable applet options and features which are not essential.
|
||||||
|
Many applet options have dedicated config options to (de)select them
|
||||||
|
under that applet; this options enables those options which have no
|
||||||
|
individual config item for them.
|
||||||
|
|
||||||
|
Select this if you plan to use busybox on full-blown desktop machine
|
||||||
|
with common Linux distro, which needs higher level of command-line
|
||||||
|
compatibility.
|
||||||
|
|
||||||
|
If you are preparing your build to be used on an embedded box
|
||||||
|
where you have tighter control over the entire set of userspace
|
||||||
|
tools, you can unselect this option for smaller code size.

|

|
bool "Provide compatible behavior for rare corner cases (bigger code)"

|
default n
|
||||||
|
help
|
||||||
|
This option makes grep, sed etc handle rare corner cases
|
||||||
|
(embedded NUL bytes and such). This makes code bigger and uses
|
||||||
|
some GNU extensions in libc. You probably only need this option
|
||||||
|
if you plan to run busybox on desktop.
|
||||||

bool "Building for Fedora distribution"

help
|
||||||

This option makes some tools behave like they do on Fedora.
|
||||||
|
|
||||||
|
At the time of this writing (2017-08) this only affects uname:
|
||||||
|
normally, uname -p (processor) and uname -i (platform)
|
||||||
|
are shown as "unknown", but with this option uname -p
|
||||||
|
shows the same string as uname -m (machine type),
|
||||||
|
and so does uname -i unless machine type is i486/i586/i686 -
|
||||||
|
then uname -i shows "i386".

|
||||||
|
bool "Enable obsolete features removed before SUSv3"
|
||||||
|
default y

help
|
||||||
|
This option will enable backwards compatibility with SuSv2,
|
||||||
|
specifically, old-style numeric options ('command -1 <file>')
|
||||||
|
will be supported in head, tail, and fold. (Note: should
|
||||||
|
affect renice too.)
|
||||||
|
|
||||||
|
config LONG_OPTS
|
||||||
|
bool "Support --long-options"
|
||||||
|
default y
|
||||||
|
help
|
||||||
|
Enable this if you want busybox applets to use the gnu --long-option
|
||||||
|
style, in addition to single character -a -b -c style options.
|
||||||
|
|
||||||
|
config SHOW_USAGE
|
||||||
|
bool "Show applet usage messages"
|
||||||
|
default y
|
||||||
|
help
|
||||||
|
Enabling this option, applets will show terse help messages
|
||||||
|
when invoked with wrong arguments.
|
||||||
|
If you do not want to show any (helpful) usage message when
|
||||||
|
issuing wrong command syntax, you can say 'N' here,
|
||||||
|
saving approximately 7k.
|
||||||
|
|
||||||
|
config FEATURE_VERBOSE_USAGE
|
||||||
|
bool "Show verbose applet usage messages"
|
||||||
|
default y
|
||||||
|
depends on SHOW_USAGE
|
||||||
|
help
|
||||||
|
All applets will show verbose help messages when invoked with --help.
|
||||||
|
This will add a lot of text to the binary.
|
||||||
|
|
||||||
|
config FEATURE_COMPRESS_USAGE
|
||||||
|
bool "Store applet usage messages in compressed form"
|
||||||
|
default y
|
||||||
|
depends on SHOW_USAGE
|
||||||
|
help
|
||||||
|
Store usage messages in .bz2 compressed form, uncompress them
|
||||||
|
on-the-fly when "APPLET --help" is run.
|
||||||
|
|
||||||
|
If you have a really tiny busybox with few applets enabled (and
|
||||||
|
bunzip2 isn't one of them), the overhead of the decompressor might
|
||||||
|
be noticeable. Also, if you run executables directly from ROM
|
||||||
|
and have very little memory, this might not be a win. Otherwise,
|
||||||
|
you probably want this.
|
||||||
|
|
||||||
|
config LFS
|
||||||
|
bool "Support files > 2 GB"
|
||||||
|
default y
|
||||||
|
help
|
||||||
|
If you need to work with large files, enable this option.
|
||||||
|
This will have no effect if your kernel or your C
|
||||||
|
library lacks large file support for large files. Some of the

detector. To enable dmalloc, before running busybox you will
|
||||||
|
want to properly set your environment, for example:
|
||||||
|
export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
|
||||||
|
The 'debug=' value is generated using the following command
|
||||||
|
dmalloc -p log-stats -p log-non-free -p log-bad-space \
|
||||||
|
-p log-elapsed-time -p check-fence -p check-heap \

Electric-fence support:
|

|
-----------------------
|

|
This enables compiling with Electric-fence support. Electric
|
||||||
|
fence is another very useful malloc debugging library which uses
|
||||||
|
your computer's virtual memory hardware to detect illegal memory
|
||||||
|
accesses. This support will make busybox be considerably larger
|
||||||
|
and run slower, so you should leave this option disabled unless
|
||||||
|
you are hunting a hard to find memory problem.

Building:
|
||||||
|
=========
|
||||||
|
|
||||||
|
The BusyBox build process is similar to the Linux kernel build:
|
||||||
|
|
||||||
|
make menuconfig # This creates a file called ".config"
|
||||||
|
make # This creates the "busybox" executable
|
||||||
|
make install # or make CONFIG_PREFIX=/path/from/root install
|
||||||
|
|
||||||
|
The full list of configuration and install options is available by typing:
|
||||||
|
|
||||||
|
make help
|
||||||
|
|
||||||
|
Quick Start:
|
||||||
|
============
|
||||||
|
|
||||||
|
The easy way to try out BusyBox for the first time, without having to install
|
||||||
|
it, is to enable all features and then use "standalone shell" mode with a
|
||||||
|
blank command $PATH.
|
||||||
|
|
||||||
|
To enable all features, use "make defconfig", which produces the largest
|
||||||
|
general-purpose configuration. It's allyesconfig minus debugging options,
|
||||||
|
optional packaging choices, and a few special-purpose features requiring
|
||||||
|
extra configuration to use. Then enable "standalone shell" feature:
|
||||||
|
|
||||||
|
make defconfig
|
||||||
|
make menuconfig
|
||||||
|
# select Busybox Settings
|
||||||
|
# then General Configuration
|
||||||
|
# then exec prefers applets
|
||||||
|
# exit back to top level menu
|
||||||
|
# select Shells
|
||||||
|
# then Standalone shell
|
||||||
|
# exit back to top level menu
|
||||||
|
# exit and save new configuration
|
||||||
|
# OR
|
||||||
|
# use these commands to modify .config directly:
|
||||||
|
sed -e 's/.*FEATURE_PREFER_APPLETS.*/CONFIG_FEATURE_PREFER_APPLETS=y/' -i .config
|
||||||
|
sed -e 's/.*FEATURE_SH_STANDALONE.*/CONFIG_FEATURE_SH_STANDALONE=y/' -i .config
|
||||||
|
make
|
||||||
|
PATH= ./busybox ash
|
||||||
|
|
||||||
|
Standalone shell mode causes busybox's built-in command shell to run
|
||||||
|
any built-in busybox applets directly, without looking for external
|
||||||
|
programs by that name. Supplying an empty command path (as above) means
|
||||||
|
the only commands busybox can find are the built-in ones.
|
||||||
|
|
||||||
|
Note that the standalone shell requires CONFIG_BUSYBOX_EXEC_PATH
|
||||||
|
to be set appropriately, depending on whether or not /proc/self/exe is
|
||||||
|
available. If you do not have /proc, then point that config option
|
||||||
|
to the location of your busybox binary, usually /bin/busybox.
|
||||||
|
Another solution is to patch the kernel (see
|
||||||
|
examples/linux-*_proc_self_exe.patch) to make exec("/proc/self/exe")
|
||||||
|
always work.
|
||||||
|
|
||||||
|
Configuring Busybox:
|
||||||
|
====================
|
||||||
|
|
||||||
|
Busybox is optimized for size, but enabling the full set of functionality
|
||||||
|
still results in a fairly large executable -- more than 1 megabyte when
|
||||||
|
statically linked. To save space, busybox can be configured with only the
|
||||||
|
set of applets needed for each environment. The minimal configuration, with
|
||||||
|
all applets disabled, produces a 4k executable. (It's useless, but very small.)
|
||||||
|
|
||||||
|
The manual configurator "make menuconfig" modifies the existing configuration.
|
||||||
|
(For systems without ncurses, try "make config" instead.) The two most
|
||||||
|
interesting starting configurations are "make allnoconfig" (to start with
|
||||||
|
everything disabled and add just what you need), and "make defconfig" (to
|
||||||
|
start with everything enabled and remove what you don't need). If menuconfig
|
||||||
|
is run without an existing configuration, make defconfig will run first to
|
||||||
|
create a known starting point.
|
||||||
|
|
||||||
|
Other starting configurations (mostly used for testing purposes) include
|
||||||
|
"make allbareconfig" (enables all applets but disables all optional features),
|
||||||
|
"make allyesconfig" (enables absolutely everything including debug features),
|
||||||
|
and "make randconfig" (produce a random configuration). The configs/ directory
|
||||||
|
contains a number of additional configuration files ending in _defconfig which
|
||||||
|
are useful in specific cases. "make help" will list them.
|
||||||
|
|
||||||
|
Configuring BusyBox produces a file ".config", which can be saved for future
|
||||||
|
use. Run "make oldconfig" to bring a .config file from an older version of
|
||||||
|
busybox up to date.
|
||||||
|
|
||||||
|
Installing Busybox:
|
||||||
|
===================
|
||||||
|
|
||||||
|
Busybox is a single executable that can behave like many different commands,
|
||||||
|
and BusyBox uses the name it was invoked under to determine the desired
|
||||||
|
behavior. (Try "mv busybox ls" and then "./ls -l".)
|
||||||
|
|
||||||
|
Installing busybox consists of creating symlinks (or hardlinks) to the busybox
|
||||||
|
binary for each applet enabled in busybox, and making sure these symlinks are
|
||||||
|
in the shell's command $PATH. Running "make install" creates these symlinks,
|
||||||
|
or "make install-hardlinks" creates hardlinks instead (useful on systems with
|
||||||
|
a limited number of inodes). This install process uses the file
|
||||||
|
"busybox.links" (created by make), which contains the list of enabled applets
|
||||||
|
and the path at which to install them.
|
||||||
|
|
||||||
|
Installing links to busybox is not always necessary. The special applet name
|
||||||
|
"busybox" (or with any optional suffix, such as "busybox-static") uses the
|
||||||
|
first argument to determine which applet to behave as, for example
|
||||||
|
"./busybox cat LICENSE". (Running the busybox applet with no arguments gives
|
||||||
|
a list of all enabled applets.) The standalone shell can also call busybox
|
||||||
|
applets without links to busybox under other names in the filesystem. You can
|
||||||
|
also configure a standalone install capability into the busybox base applet,
|
||||||
|
and then install such links at runtime with one of "busybox --install" (for
|
||||||
|
hardlinks) or "busybox --install -s" (for symlinks).
|
||||||
|
|
||||||
|
If you enabled the busybox shared library feature (libbusybox.so) and want
|
||||||
|
to run tests without installing, set your LD_LIBRARY_PATH accordingly when
|
||||||
|
running the executable:
|
||||||
|
|
||||||
|
LD_LIBRARY_PATH=`pwd` ./busybox
|
||||||
|
|
||||||
|
Building out-of-tree:
|
||||||
|
=====================
|
||||||
|
|
||||||
|
By default, the BusyBox build puts its temporary files in the source tree.
|
||||||
|
Building from a read-only source tree, or building multiple configurations from
|
||||||
|
the same source directory, requires the ability to put the temporary files
|
||||||
|
somewhere else.
|
||||||
|
|
||||||
|
To build out of tree, cd to an empty directory and configure busybox from there:
|
||||||
|
|
||||||
|
make KBUILD_SRC=/path/to/source -f /path/to/source/Makefile defconfig
|
||||||
|
make
|
||||||
|
make install
|
||||||
|
|
||||||
|
Alternately, use the O=$BUILDPATH option (with an absolute path) during the
|
||||||
|
configuration step, as in:
|
||||||
|
|
||||||
|
make O=/some/empty/directory allyesconfig
|
||||||
|
cd /some/empty/directory
|
||||||
|
make
|
||||||
|
make CONFIG_PREFIX=. install
|
||||||
|
|
||||||

your programs, too.
|

When we speak of free software, we are referring to freedom, not

|
in new free programs; and that you know you can do these things.
|

|
|
||||||
|
To protect your rights, we need to make restrictions that forbid

|
you have. You must make sure that they, too, receive or can get the

(2) offer you this license which gives you legal permission to copy,

want its recipients to know that what they have is not the original, so
|
||||||
|
that any problems introduced by others will not reflect on the original
|
||||||
|
authors' reputations.
|
||||||
|
|
||||||
|
Finally, any free program is threatened constantly by software
|
||||||
|
patents. We wish to avoid the danger that redistributors of a free
|
||||||
|
program will individually obtain patent licenses, in effect making the
|
||||||
|
program proprietary. To prevent this, we have made it clear that any
|
||||||
|
patent must be licensed for everyone's free use or not licensed at all.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and
|
||||||
|
modification follow.
|
||||||
|
|
||||||
|
GNU GENERAL PUBLIC LICENSE
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License applies to any program or other work which contains
|
||||||
|
a notice placed by the copyright holder saying it may be distributed
|
||||||
|
under the terms of this General Public License. The "Program", below,
|
||||||
|
refers to any such program or work, and a "work based on the Program"
|
||||||
|
means either the Program or any derivative work under copyright law:
|
||||||
|
that is to say, a work containing the Program or a portion of it,
|
||||||
|
either verbatim or with modifications and/or translated into another
|
||||||
|
language. (Hereinafter, translation is included without limitation in
|
||||||
|
the term "modification".) Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
Activities other than copying, distribution and modification are not
|
||||||
|
covered by this License; they are outside its scope. The act of
|
||||||
|
running the Program is not restricted, and the output from the Program
|
||||||
|
is covered only if its contents constitute a work based on the
|
||||||
|
Program (independent of having been made by running the Program).
|
||||||
|
Whether that is true depends on what the Program does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Program's
|
||||||
|
source code as you receive it, in any medium, provided that you
|
||||||
|
conspicuously and appropriately publish on each copy an appropriate
|
||||||
|
copyright notice and disclaimer of warranty; keep intact all the
|
||||||
|
notices that refer to this License and to the absence of any warranty;
|
||||||
|
and give any other recipients of the Program a copy of this License
|
||||||
|
along with the Program.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy, and
|
||||||
|
you may at your option offer warranty protection in exchange for a fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Program or any portion
|
||||||
|
of it, thus forming a work based on the Program, and copy and
|
||||||
|
distribute such modifications or work under the terms of Section 1
|
||||||
|
above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) You must cause the modified files to carry prominent notices
|
||||||
|
stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
b) You must cause any work that you distribute or publish, that in
|
||||||
|
whole or in part contains or is derived from the Program or any
|
||||||
|
part thereof, to be licensed as a whole at no charge to all third
|
||||||
|
parties under the terms of this License.
|
||||||
|
|
||||||
|
c) If the modified program normally reads commands interactively
|
||||||
|
when run, you must cause it, when started running for such
|
||||||
|
interactive use in the most ordinary way, to print or display an
|
||||||
|
announcement including an appropriate copyright notice and a
|
||||||
|
notice that there is no warranty (or else, saying that you provide
|
||||||
|
a warranty) and that users may redistribute the program under
|
||||||
|
these conditions, and telling the user how to view a copy of this
|
||||||
|
License. (Exception: if the Program itself is interactive but
|
||||||
|
does not normally print such an announcement, your work based on
|
||||||
|
the Program is not required to print an announcement.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If
|
||||||
|
identifiable sections of that work are not derived from the Program,
|
||||||
|
and can be reasonably considered independent and separate works in
|
||||||
|
themselves, then this License, and its terms, do not apply to those
|
||||||
|
sections when you distribute them as separate works. But when you
|
||||||
|
distribute the same sections as part of a whole which is a work based
|
||||||
|
on the Program, the distribution of the whole must be on the terms of
|
||||||
|
this License, whose permissions for other licensees extend to the
|
||||||
|
entire whole, and thus to each and every part regardless of who wrote it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest
|
||||||
|
your rights to work written entirely by you; rather, the intent is to
|
||||||
|
exercise the right to control the distribution of derivative or
|
||||||
|
collective works based on the Program.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Program
|
||||||
|
with the Program (or with a work based on the Program) on a volume of
|
||||||
|
a storage or distribution medium does not bring the other work under
|
||||||
|
the scope of this License.
|
||||||
|
|
||||||
|
3. You may copy and distribute the Program (or a work based on it,
|
||||||
|
under Section 2) in object code or executable form under the terms of
|
||||||
|
Sections 1 and 2 above provided that you also do one of the following:
|
||||||
|
|
||||||
|
a) Accompany it with the complete corresponding machine-readable
|
||||||
|
source code, which must be distributed under the terms of Sections
|
||||||
|
1 and 2 above on a medium customarily used for software interchange; or,
|
||||||
|
|
||||||
|
b) Accompany it with a written offer, valid for at least three
|
||||||
|
years, to give any third party, for a charge no more than your
|
||||||
|
cost of physically performing source distribution, a complete
|
||||||
|
machine-readable copy of the corresponding source code, to be
|
||||||
|
distributed under the terms of Sections 1 and 2 above on a medium
|
||||||
|
customarily used for software interchange; or,
|
||||||
|
|
||||||
|
c) Accompany it with the information you received as to the offer
|
||||||
|
to distribute corresponding source code. (This alternative is
|
||||||
|
allowed only for noncommercial distribution and only if you
|
||||||
|
received the program in object code or executable form with such
|
||||||
|
an offer, in accord with Subsection b above.)
|
||||||
|
|
||||||
|
The source code for a work means the preferred form of the work for
|
||||||
|
making modifications to it. For an executable work, complete source
|
||||||
|
code means all the source code for all modules it contains, plus any
|
||||||
|
associated interface definition files, plus the scripts used to
|
||||||
|
control compilation and installation of the executable. However, as a
|
||||||
|
special exception, the source code distributed need not include
|
||||||
|
anything that is normally distributed (in either source or binary
|
||||||
|
form) with the major components (compiler, kernel, and so on) of the
|
||||||
|
operating system on which the executable runs, unless that component
|
||||||
|
itself accompanies the executable.
|
||||||
|
|
||||||
|
If distribution of executable or object code is made by offering
|
||||||
|
access to copy from a designated place, then offering equivalent
|
||||||
|
access to copy the source code from the same place counts as
|
||||||
|
distribution of the source code, even though third parties are not
|
||||||
|
compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
4. You may not copy, modify, sublicense, or distribute the Program
|
||||||
|
except as expressly provided under this License. Any attempt
|
||||||
|
otherwise to copy, modify, sublicense or distribute the Program is
|
||||||
|
void, and will automatically terminate your rights under this License.
|
||||||
|
However, parties who have received copies, or rights, from you under
|
||||||
|
this License will not have their licenses terminated so long as such
|
||||||
|
parties remain in full compliance.
|
||||||
|
|
||||||
|
5. You are not required to accept this License, since you have not
|
||||||
|
signed it. However, nothing else grants you permission to modify or
|
||||||
|
distribute the Program or its derivative works. These actions are
|
||||||
|
prohibited by law if you do not accept this License. Therefore, by
|
||||||
|
modifying or distributing the Program (or any work based on the
|
||||||
|
Program), you indicate your acceptance of this License to do so, and
|
||||||
|
all its terms and conditions for copying, distributing or modifying
|
||||||
|
the Program or works based on it.
|
||||||
|
|
||||||
|
6. Each time you redistribute the Program (or any work based on the
|
||||||
|
Program), the recipient automatically receives a license from the
|
||||||
|
original licensor to copy, distribute or modify the Program subject to
|
||||||
|
these terms and conditions. You may not impose any further
|
||||||
|
restrictions on the recipients' exercise of the rights granted herein.
|
||||||
|
You are not responsible for enforcing compliance by third parties to
|
||||||
|
this License.
|
||||||
|
|
||||||
|
7. If, as a consequence of a court judgment or allegation of patent
|
||||||
|
infringement or for any other reason (not limited to patent issues),
|
||||||
|
conditions are imposed on you (whether by court order, agreement or
|
||||||
|
otherwise) that contradict the conditions of this License, they do not
|
||||||
|
excuse you from the conditions of this License. If you cannot
|
||||||
|
distribute so as to satisfy simultaneously your obligations under this
|
||||||
|
License and any other pertinent obligations, then as a consequence you
|
||||||
|
may not distribute the Program at all. For example, if a patent
|
||||||
|
license would not permit royalty-free redistribution of the Program by
|
||||||
|
all those who receive copies directly or indirectly through you, then
|
||||||
|
the only way you could satisfy both it and this License would be to
|
||||||
|
refrain entirely from distribution of the Program.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under
|
||||||
|
any particular circumstance, the balance of the section is intended to
|
||||||
|
apply and the section as a whole is intended to apply in other
|
||||||
|
circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any
|
||||||
|
patents or other property right claims or to contest validity of any
|
||||||
|
such claims; this section has the sole purpose of protecting the
|
||||||
|
integrity of the free software distribution system, which is
|
||||||
|
implemented by public license practices. Many people have made
|
||||||
|
generous contributions to the wide range of software distributed
|
||||||
|
through that system in reliance on consistent application of that
|
||||||
|
system; it is up to the author/donor to decide if he or she is willing
|
||||||
|
to distribute software through any other system and a licensee cannot
|
||||||
|
impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to
|
||||||
|
be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
8. If the distribution and/or use of the Program is restricted in
|
||||||
|
certain countries either by patents or by copyrighted interfaces, the
|
||||||
|
original copyright holder who places the Program under this License
|
||||||
|
may add an explicit geographical distribution limitation excluding
|
||||||
|
those countries, so that distribution is permitted only in or among
|
||||||
|
countries not thus excluded. In such case, this License incorporates
|
||||||
|
the limitation as if written in the body of this License.
|
||||||
|
|
||||||
|
9. The Free Software Foundation may publish revised and/or new versions
|
||||||
|
of the General Public License from time to time. Such new versions will
|
||||||
|
be similar in spirit to the present version, but may differ in detail to
|
||||||
|
address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Program
|
||||||
|
specifies a version number of this License which applies to it and "any
|
||||||
|
later version", you have the option of following the terms and conditions
|
||||||
|
either of that version or of any later version published by the Free
|
||||||
|
Software Foundation. If the Program does not specify a version number of
|
||||||
|
this License, you may choose any version ever published by the Free Software
|
||||||
|
Foundation.
|
||||||
|
|
||||||
|
10. If you wish to incorporate parts of the Program into other free
|
||||||
|
programs whose distribution conditions are different, write to the author
|
||||||
|
to ask for permission. For software which is copyrighted by the Free
|
||||||
|
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||||
|
make exceptions for this. Our decision will be guided by the two goals
|
||||||
|
of preserving the free status of all derivatives of our free software and
|
||||||
|
of promoting the sharing and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||||
|
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||||
|
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||||
|
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||||
|
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||||
|
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||||
|
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||||
|
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||||
|
REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||||
|
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||||
|
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||||
|
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||||
|
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||||
|
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||||
|
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||||
|
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||||
|
POSSIBILITY OF SUCH DAMAGES.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS
|
||||||
|
|
||||||
|
How to Apply These Terms to Your New Programs
|
||||||
|
|
||||||
|
If you develop a new program, and you want it to be of the greatest
|
||||||
|
possible use to the public, the best way to achieve this is to make it
|
||||||
|
free software which everyone can redistribute and change under these terms.
|
||||||
|
|
||||||
|
To do so, attach the following notices to the program. It is safest
|
||||||
|
to attach them to the start of each source file to most effectively
|
||||||
|
convey the exclusion of warranty; and each file should have at least
|
||||||
|
the "copyright" line and a pointer to where the full notice is found.
|
||||||
|
|
||||||
|
<one line to give the program's name and a brief idea of what it does.>
|
||||||
|
Copyright (C) <year> <name of author>
|
||||||
|
|
||||||
|
This program is free software; you can redistribute it and/or modify
|
||||||
|
it under the terms of the GNU General Public License as published by
|
||||||
|
the Free Software Foundation; either version 2 of the License, or
|
||||||
|
(at your option) any later version.
|
||||||
|
|
||||||
|
This program is distributed in the hope that it will be useful,
|
||||||
|
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||||
|
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||||
|
GNU General Public License for more details.
|
||||||
|
|
||||||
|
You should have received a copy of the GNU General Public License
|
||||||
|
along with this program; if not, write to the Free Software
|
||||||
|
Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
|
||||||
|
|
||||||
|
|
||||||
|
Also add information on how to contact you by electronic and paper mail.
|
||||||
|
|
||||||
|
If the program is interactive, make it output a short notice like this
|
||||||
|
when it starts in an interactive mode:
|
||||||
|
|
||||||
|
Gnomovision version 69, Copyright (C) year name of author
|
||||||
|
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||||
|
This is free software, and you are welcome to redistribute it
|
||||||
|
under certain conditions; type `show c' for details.
|
||||||
|
|
||||||
|
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||||
|
parts of the General Public License. Of course, the commands you use may
|
||||||
|
be called something other than `show w' and `show c'; they could even be
|
||||||
|
mouse-clicks or menu items--whatever suits your program.
|
||||||
|
|
||||||
|
You should also get your employer (if you work as a programmer) or your
|
||||||
|
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||||
|
necessary. Here is a sample; alter the names:
|
||||||
|
|
||||||
|
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||||
|
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||||||
|
proprietary programs. If your program is a subroutine library, you may
|
||||||
|
consider it more useful to permit linking proprietary applications with the
|
||||||
|
library. If this is what you want to do, use the GNU Library General
|
||||||
|
Public License instead of this License.

Why an applet can't be NOFORK or NOEXEC?
|
||||||
|
|
||||||
|
Why can't be NOFORK:
|
||||||
|
interactive: may wait for user input, ^C has to work
|
||||||
|
spawner: "tool PROG ARGS" which changes program state and execs - must fork
|
||||||
|
changes state: e.g. environment, signal handlers
|
||||||
|
leaks: does not free allocated memory or opened fds
|
||||||
|
alloc+xfunc: xmalloc, then xfunc - leaks memory if xfunc dies
|
||||||
|
open+xfunc: opens fd, then calls xfunc - fd is leaked if xfunc dies
|
||||||
|
talks to network/serial/etc: it's not known how long the delay can be,
|
||||||
|
it's reasonable to expect it might be many seconds
|
||||||
|
(even if usually it is not), so ^C has to work
|
||||||
|
runner: sometimes may run for long(ish) time, and/or works with network:
|
||||||
|
^C has to work (cat BIGFILE, chmod -R, ftpget, nc)
|
||||||
|
|
||||||
|
"runners" can become eligible after shell is taught ^C to interrupt NOFORKs,
|
||||||
|
need to be inspected that they do not fall into alloc+xfunc, open+xfunc,
|
||||||
|
leak categories.
|
||||||
|
|
||||||
|
Why can't be NOEXEC:
|
||||||
|
suid: runs under different uid - must fork+exec
|
||||||
|
if it's important that /proc/PID/cmdline and comm are correct.
|
||||||
|
("pkill sh" killing itself before it kills real "sh" is no fun)
|
||||||
|
|
||||||
|
Why shouldn't be NOFORK/NOEXEC:
|
||||||
|
rare: not started often enough to bother optimizing (example: poweroff)
|
||||||
|
daemon: runs indefinitely; these are also always fit "rare" category
|
||||||
|
longterm: often runs for a long time (many seconds), execing makes
|
||||||
|
memory footprint smaller
|
||||||
|
complex: no immediately obvious reason why NOFORK wouldn't work,
|
||||||
|
but does some non-obvoius operations (example: fuser, lsof, losetup);
|
||||||
|
detailed audit often turns out that it's a leaker
|
||||||
|
hardware: performs unusual hardware ops which may take long,
|
||||||
|
or even hang due to hardware or firmware bugs
|
||||||
|
|
||||||
|
Interesting example of "interactive" applet which is nevertheless can be
|
||||||
|
(and is) NOEXEC is "rm". Yes, "rm -i" is interactive - but it's not that typical
|
||||||
|
for users to keep it waiting for many minutes, whereas running "rm" in shell
|
||||||
|
is very typical, and speeding up this common use via NOEXEC is useful.
|
||||||
|
IOW: rm is "interactive", but not "longterm".
|
||||||
|
|
||||||
|
Interesting example of an applet which can be NOFORK but if not,
|
||||||
|
then should not be NOEXEC, is "usleep". As NOFORK, it amount to simply
|
||||||
|
nanosleep()ing in the calling program (usually shell). No memory wasted.
|
||||||
|
But if ran as NOEXEC, it would create a potentially long-term process,
|
||||||
|
which would be taking more memory because it did not exec
|
||||||
|
and did not free much of the copied memory of the parent
|
||||||
|
(COW helps with this only as long as parent doesn't modify its memory).

What is busybox:
|
||||||
|
|
||||||
|
BusyBox combines tiny versions of many common UNIX utilities into a single
|
||||||
|
small executable. It provides minimalist replacements for most of the
|
||||||
|
utilities you usually find in bzip2, coreutils, dhcp, diffutils, e2fsprogs,
|
||||||
|
file, findutils, gawk, grep, inetutils, less, modutils, net-tools, procps,
|
||||||
|
sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The utilities
|
||||||
|
in BusyBox often have fewer options than their full-featured cousins;
|
||||||
|
however, the options that are included provide the expected functionality
|
||||||
|
and behave very much like their larger counterparts.
|
||||||
|
|
||||||
|
BusyBox has been written with size-optimization and limited resources in
|
||||||
|
mind, both to produce small binaries and to reduce run-time memory usage.
|
||||||
|
Busybox is also extremely modular so you can easily include or exclude
|
||||||
|
commands (or features) at compile time. This makes it easy to customize
|
||||||
|
embedded systems; to create a working system, just add /dev, /etc, and a
|
||||||
|
Linux kernel. Busybox (usually together with uClibc) has also been used as
|
||||||
|
a component of "thin client" desktop systems, live-CD distributions, rescue
|
||||||
|
disks, installers, and so on.
|
||||||
|
|
||||||
|
BusyBox provides a fairly complete POSIX environment for any small system,
|
||||||
|
both embedded environments and more full featured systems concerned about
|
||||||
|
space. Busybox is slowly working towards implementing the full Single Unix
|
||||||
|
Specification V3 (http://www.opengroup.org/onlinepubs/009695399/), but isn't
|
||||||
|
there yet (and for size reasons will probably support at most UTF-8 for
|
||||||
|
internationalization). We are also interested in passing the Linux Test
|
||||||
|
Project (http://ltp.sourceforge.net).
|
||||||
|
|
||||||
|
----------------
|
||||||
|
|
||||||
|
Using busybox:
|
||||||
|
|
||||||
|
BusyBox is extremely configurable. This allows you to include only the
|
||||||
|
components and options you need, thereby reducing binary size. Run 'make
|
||||||
|
config' or 'make menuconfig' to select the functionality that you wish to
|
||||||
|
enable. (See 'make help' for more commands.)
|
||||||
|
|
||||||
|
The behavior of busybox is determined by the name it's called under: as
|
||||||
|
"cp" it behaves like cp, as "sed" it behaves like sed, and so on. Called
|
||||||
|
as "busybox" it takes the second argument as the name of the applet to
|
||||||
|
run (I.E. "./busybox ls -l /proc").
|
||||||
|
|
||||||
|
The "standalone shell" mode is an easy way to try out busybox; this is a
|
||||||
|
command shell that calls the built-in applets without needing them to be
|
||||||
|
installed in the path. (Note that this requires /proc to be mounted, if
|
||||||
|
testing from a boot floppy or in a chroot environment.)
|
||||||
|
|
||||||
|
The build automatically generates a file "busybox.links", which is used by
|
||||||
|
'make install' to create symlinks to the BusyBox binary for all compiled in
|
||||||
|
commands. This uses the CONFIG_PREFIX environment variable to specify
|
||||||
|
where to install, and installs hardlinks or symlinks depending
|
||||||
|
on the configuration preferences. (You can also manually run
|
||||||
|
the install script at "applets/install.sh").

Bugs:
|
||||||
|
|
||||||
|
if you find bugs, please submit a detailed bug report to the busybox mailing
|
||||||
|
list at busybox@busybox.net. a well-written bug report should include a
|
||||||
|
transcript of a shell session that demonstrates the bad behavior and enables
|
||||||
|
anyone else to duplicate the bug on their own machine. the following is such
|
||||||
|
an example:
|
||||||
|
|
||||||
|

|
||||||
|
from: diligent@testing.linux.org
|
||||||
|
subject: /bin/date doesn't work
|
||||||
|
|
||||||
|
package: busybox
|
||||||
|
version: 1.00
|
||||||
|
|
||||||
|
when i execute busybox 'date' it produces unexpected results.
|
||||||
|
with gnu date i get the following output:
|
||||||
|
|
||||||
|
$ date
|
||||||
|
fri oct 8 14:19:41 mdt 2004
|
||||||
|
|
||||||
|
but when i use busybox date i get this instead:
|
||||||
|
|
||||||
|
$ date
|
||||||
|
illegal instruction
|
||||||
|
|
||||||
|
i am using debian unstable, kernel version 2.4.25-vrs2 on a netwinder,
|
||||||
|
and the latest uclibc from cvs.

|
||||||
|
|
||||||
|
note the careful description and use of examples showing not only what
|
||||||
|
busybox does, but also a counter example showing what an equivalent app
|
||||||
|
does (or pointing to the text of a relevant standard). Bug reports lacking
|
||||||
|
such detail may never be fixed... Thanks for understanding.
|
||||||
|
|
||||||
|
----------------
|
||||||
|
|
||||||
|
Portability:
|
||||||
|
|
||||||
|
Busybox is developed and tested on Linux 2.4 and 2.6 kernels, compiled
|
||||||
|
with gcc (the unit-at-a-time optimizations in version 3.4 and later are
|
||||||
|
worth upgrading to get, but older versions should work), and linked against
|
||||||
|
uClibc (0.9.27 or greater) or glibc (2.2 or greater). In such an
|
||||||
|
environment, the full set of busybox features should work, and if
|
||||||
|
anything doesn't we want to know about it so we can fix it.
|
||||||
|
|
||||||
|
There are many other environments out there, in which busybox may build
|
||||||
|
and run just fine. We just don't test them. Since busybox consists of a
|
||||||
|
large number of more or less independent applets, portability is a question
|
||||||
|
of which features work where. Some busybox applets (such as cat and rm) are
|
||||||
|
highly portable and likely to work just about anywhere, while others (such as
|
||||||
|
insmod and losetup) require recent Linux kernels with recent C libraries.
|
||||||
|
|
||||||
|
Earlier versions of Linux and glibc may or may not work, for any given
|
||||||
|
configuration. Linux 2.2 or earlier should mostly work (there's still
|
||||||
|
some support code in things like mount.c) but this is no longer regularly
|
||||||
|
tested, and inherently won't support certain features (such as long files
|
||||||
|
and --bind mounts). The same is true for glibc 2.0 and 2.1: expect a higher
|
||||||
|
testing and debugging burden using such old infrastructure. (The busybox
|
||||||
|
developers are not very interested in supporting these older versions, but
|
||||||
|
will probably accept small self-contained patches to fix simple problems.)
|
||||||
|
|
||||||
|
Some environments are not recommended. Early versions of uClibc were buggy
|
||||||
|
and missing many features: upgrade. Linking against libc5 or dietlibc is
|
||||||
|
not supported and not interesting to the busybox developers. (The first is
|
||||||
|
obsolete and has no known size or feature advantages over uClibc, the second
|
||||||
|
has known bugs that its developers have actively refused to fix.) Ancient
|
||||||
|
Linux kernels (2.0.x and earlier) are similarly uninteresting.
|
||||||
|
|
||||||
|
In theory it's possible to use Busybox under other operating systems (such as
|
||||||
|
MacOS X, Solaris, Cygwin, or the BSD Fork Du Jour). This generally involves
|
||||||
|
a different kernel and a different C library at the same time. While it
|
||||||
|
should be possible to port the majority of the code to work in one of
|
||||||
|
these environments, don't be surprised if it doesn't work out of the box. If
|
||||||
|
you're into that sort of thing, start small (selecting just a few applets)
|
||||||
|
and work your way up.
|
||||||
|
|
||||||
|
In 2005 Shaun Jackman has ported busybox to a combination of newlib
|
||||||
|
and libgloss, and some of his patches have been integrated.
|
||||||
|
|
||||||
|
Supported hardware:
|
||||||
|
|
||||||
|
BusyBox in general will build on any architecture supported by gcc. We
|
||||||
|
support both 32 and 64 bit platforms, and both big and little endian
|
||||||
|
systems.
|
||||||
|
|
||||||
|
Under 2.4 Linux kernels, kernel module loading was implemented in a
|
||||||
|
platform-specific manner. Busybox's insmod utility has been reported to
|
||||||
|
work under ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC, S390,
|
||||||
|
SH3/4/5, Sparc, and v850e. Anything else probably won't work.
|
||||||
|
|
||||||
|
The module loading mechanism for the 2.6 kernel is much more generic, and
|
||||||
|
we believe 2.6.x kernel module loading support should work on all
|
||||||
|
architectures supported by the kernel.

Rob Landley suggested this:
|
||||||
|
Implement bb_realpath() that can handle NULL on non-glibc.
|
||||||
|
|
||||||
|
sh
|
||||||
|
The command shell situation is a mess. We have two different
|
||||||
|
shells that don't really share any code, and the "standalone shell" doesn't
|
||||||
|
work all that well (especially not in a chroot environment), due to apps not
|
||||||
|
being reentrant.
|
||||||
|
|
||||||
|
Do a SUSv3 audit
|
||||||
|
Look at the full Single Unix Specification version 3 (available online at
|
||||||
|
"http://www.opengroup.org/onlinepubs/009695399/nfindex.html") and
|
||||||
|
figure out which of our apps are compliant, and what we're missing that
|
||||||
|
we might actually care about.
|
||||||
|
|
||||||
|
Even better would be some kind of automated compliance test harness that
|
||||||
|
exercises each command line option and the various corner cases.
|
||||||
|
|
||||||
|
Internationalization
|
||||||
|
How much internationalization should we do?
|
||||||
|
|
||||||
|
The low hanging fruit is UTF-8 character set support. We should do this.
|
||||||
|
See TODO_unicode file.
|
||||||
|
|
||||||
|
We also have lots of hardwired english text messages. Consolidating this
|
||||||
|
into some kind of message table not only makes translation easier, but
|
||||||
|
also allows us to consolidate redundant (or close) strings.
|
||||||
|
|
||||||
|
We probably don't want to be bloated with locale support. (Not unless we
|
||||||
|
can cleanly export it from our underlying C library without having to
|
||||||
|
concern ourselves with it directly. Perhaps a few specific things like a
|
||||||
|
config option for "date" are low hanging fruit here?)
|
||||||
|
|
||||||
|
What level should things happen at? How much do we care about
|
||||||
|
internationalizing the text console when X11 and xterms are so much better
|
||||||
|
at it? (There's some infrastructure here we don't implement: The
|
||||||
|
"unicode_start" and "unicode_stop" shell scripts need "vt-is-UTF8" and a
|
||||||
|
--unicode option to loadkeys. That implies a real loadkeys/dumpkeys
|
||||||
|
implementation to replace loadkmap/dumpkmap. Plus messing with console font
|
||||||
|
loading. Is it worth it, or do we just say "use X"?)
|
||||||
|
|
||||||
|
Individual compilation of applets.
|
||||||
|
It would be nice if busybox had the option to compile to individual applets,
|
||||||
|
for people who want an alternate implementation less bloated than the gnu
|
||||||
|
utils (or simply with less political baggage), but without it being one big
|
||||||
|
executable.
|
||||||
|
|
||||||
|
Turning libbb into a real dll is another possibility, especially if libbb
|
||||||
|
could export some of the other library interfaces we've already more or less
|
||||||
|
got the code for (like zlib).
|
||||||
|
|
||||||
|
buildroot - Make a "dogfood" option
|
||||||
|
Busybox 1.1 will be capable of replacing most gnu packages for real world
|
||||||
|
use, such as developing software or in a live CD. It needs wider testing.
|
||||||
|
|
||||||
|
Busybox should now be able to replace bzip2, coreutils, e2fsprogs, file,
|
||||||
|
findutils, gawk, grep, inetutils, less, modutils, net-tools, patch, procps,
|
||||||
|
sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The resulting
|
||||||
|
system should be self-hosting (I.E. able to rebuild itself from source
|
||||||
|
code). This means it would need (at least) binutils, gcc, and make, or
|
||||||
|
equivalents.
|
||||||
|
|
||||||
|
It would be a good "eating our own dogfood" test if buildroot had the option
|
||||||
|
of using a "make allyesconfig" busybox instead of the all of the above
|
||||||
|
packages. Anything that's wrong with the resulting system, we can fix. (It
|
||||||
|
would be nice to be able to upgrade busybox to be able to replace bash and
|
||||||
|
diffutils as well, but we're not there yet.)
|
||||||
|
|
||||||
|
One example of an existing system that does this already is Firmware Linux:
|
||||||
|
http://www.landley.net/code/firmware
|
||||||
|
|
||||||
|
initramfs
|
||||||
|
Busybox should have a sample initramfs build script. This depends on
|
||||||
|
shell, mdev, and switch_root.
|
||||||
|
|
||||||
|
mkdep
|
||||||
|
Write a mkdep that doesn't segfault if there's a directory it doesn't
|
||||||
|
have permission to read, isn't based on manually editing the output of
|
||||||
|
lexx and yacc, doesn't make such a mess under include/config, etc.
|
||||||
|
|
||||||
|
Group globals into unions of structures.
|
||||||
|
Go through and turn all the global and static variables into structures,
|
||||||
|
and have all those structures be in a big union shared between processes,
|
||||||
|
so busybox uses less bss. (This is a big win on nommu machines.) See
|
||||||
|
sed.c and mdev.c for examples.
|
||||||
|
|
||||||
|
Go through bugs.busybox.net and close out all of that somehow.
|
||||||
|
This one's open to everybody, but I'll wind up doing it...
|
||||||
|
|
||||||
|
Bernhard Reutner-Fischer <busybox@busybox.net> suggests to look at these:
|
||||||
|
New debug options:
|
||||||
|
-Wlarger-than-127
|
||||||
|
Cleanup any big users
|
||||||
|
Collate BUFSIZ IOBUF_SIZE MY_BUF_SIZE PIPE_PROGRESS_SIZE BUFSIZE PIPESIZE
|
||||||
|
make bb_common_bufsiz1 configurable, size wise.
|
||||||
|
make pipesize configurable, size wise.
|
||||||
|
Use bb_common_bufsiz1 throughout applets!

As yet unclaimed:

||||||

|

diff
|
||||||
|
Make sure we handle empty files properly:
|
||||||
|
From the patch man page:
|
||||||
|
|
||||||
|
you can remove a file by sending out a context diff that compares
|
||||||
|
the file to be deleted with an empty file dated the Epoch. The
|
||||||
|
file will be removed unless patch is conforming to POSIX and the
|
||||||
|
-E or --remove-empty-files option is not given.
|
||||||
|
---
|
||||||
|
patch
|
||||||
|
Should have simple fuzz factor support to apply patches at an offset which
|
||||||
|
shouldn't take up too much space.
|
||||||
|
|
||||||
|
And while we're at it, a new patch filename quoting format is apparently
|
||||||
|
coming soon: http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2
|
||||||
|
|
||||||
|
Architectural issues:
|
||||||
|
|
||||||
|
bb_close() with fsync()
|
||||||
|
We should have a bb_close() in place of normal close, with a CONFIG_ option
|
||||||
|
to not just check the return value of close() for an error, but fsync().
|
||||||
|
Close can't reliably report anything useful because if write() accepted the
|
||||||
|
data then it either went out to the network or it's in cache or a pipe
|
||||||
|
buffer. Either way, there's no guarantee it'll make it to its final
|
||||||
|
destination before close() gets called, so there's no guarantee that any
|
||||||
|
error will be reported.
|
||||||
|
|
||||||
|
You need to call fsync() if you care about errors that occur after write(),
|
||||||
|
but that can have a big performance impact. So make it a config option.
|
||||||
|
---
|
||||||
|
Unify archivers
|
||||||
|
Lots of archivers have the same general infrastructure. The directory
|
||||||
|
traversal code should be factored out, and the guts of each archiver could
|
||||||
|
be some setup code and a series of callbacks for "add this file",
|
||||||
|
"add this directory", "add this symlink" and so on.
|
||||||
|
|
||||||
|
This could clean up tar and zip, and make it cheaper to add cpio and ar
|
||||||
|
write support, and possibly even cheaply add things like mkisofs or
|
||||||
|
mksquashfs someday, if they become relevant.
|
||||||
|
---
|
||||||
|
Text buffer support.
|
||||||
|
Several existing applets (sort, vi, less...) read
|
||||||
|
a whole file into memory and act on it. Use open_read_close().
|
||||||
|
---
|
||||||
|
Memory Allocation
|
||||||
|
We have a CONFIG_BUFFER mechanism that lets us select whether to do memory
|
||||||
|
allocation on the stack or the heap. Unfortunately, we're not using it much.
|
||||||
|
We need to audit our memory allocations and turn a lot of malloc/free calls
|
||||||
|
into RESERVE_CONFIG_BUFFER/RELEASE_CONFIG_BUFFER.
|
||||||
|
For a start, see e.g. make EXTRA_CFLAGS=-Wlarger-than-64
|
||||||
|
|
||||||
|
And while we're at it, many of the CONFIG_FEATURE_CLEAN_UP #ifdefs will be
|
||||||
|
optimized out by the compiler in the stack allocation case (since there's no
|
||||||
|
free for an alloca()), and this means that various cleanup loops that just
|
||||||
|
call free might also be optimized out by the compiler if written right, so
|
||||||
|
we can yank those #ifdefs too, and generally clean up the code.
|
||||||
|
---
|
||||||
|
FEATURE_CLEAN_UP
|
||||||
|
This is more an unresolved issue than a to-do item. More thought is needed.
|
||||||
|
|
||||||
|
Normally we rely on exit() to free memory, close files and unmap segments
|
||||||
|
for us. This makes most calls to free(), close(), and unmap() optional in
|
||||||
|
busybox applets that don't intend to run for very long, and optional stuff
|
||||||
|
can be omitted to save size.
|
||||||
|
|
||||||
|
The idea was raised that we could simulate fork/exit with setjmp/longjmp
|
||||||
|
for _really_ brainless embedded systems, or speed up the standalone shell
|
||||||
|
by not forking. Doing so would require a reliable FEATURE_CLEAN_UP.
|
||||||
|
Unfortunately, this isn't as easy as it sounds.
|
||||||
|
|
||||||
|
The problem is, lots of things exit(), sometimes unexpectedly (xmalloc())
|
||||||
|
and sometimes reliably (bb_perror_msg_and_die() or show_usage()). This
|
||||||
|
jumps out of the normal flow control and bypasses any cleanup code we
|
||||||
|
put at the end of our applets.
|
||||||
|
|
||||||
|
It's possible to add hooks to libbb functions like xmalloc() and xopen()
|
||||||
|
to add their entries to a linked list, which could be traversed and
|
||||||
|
freed/closed automatically. (This would need to be able to free just the
|
||||||
|
entries after a checkpoint to be usable for a forkless standalone shell.
|
||||||
|
You don't want to free the shell's own resources.)
|
||||||
|
|
||||||
|
Right now, FEATURE_CLEAN_UP is more or less a debugging aid, to make things
|
||||||
|
like valgrind happy. It's also documentation of _what_ we're trusting
|
||||||
|
exit() to clean up for us. But new infrastructure to auto-free stuff would
|
||||||
|
render the existing FEATURE_CLEAN_UP code redundant.
|
||||||
|
|
||||||
|
For right now, exit() handles it just fine.
|
||||||
|
|
||||||
|
|
||||||
|
Minor stuff:
|
||||||
|
watchdog.c could autodetect the timer duration via:
|
||||||
|
if(!ioctl (fd, WDIOC_GETTIMEOUT, &tmo)) timer_duration = 1 + (tmo / 2);
|
||||||
|
Unfortunately, that needs linux/watchdog.h and that contains unfiltered
|
||||||
|
kernel types on some distros, which breaks the build.
|
||||||
|
---
|
||||||

use bb_error_msg where appropriate: See
|

(TODO list after discussion 11.05.2009)
|
||||||
|
|
||||||
|
* shrink tc/brctl/ip
|
||||||
|
tc/brctl seem like fairly large things to try and tackle in your timeframe,
|
||||||
|
and i think people have posted attempts in the past. Adding additional
|
||||||
|
options to ip though seems reasonable.
|
||||||
|
|
||||||
|
* add tests for some applets
|
||||||
|
|
||||||
|
* implement POSIX utilities and audit them for POSIX conformance. then
|
||||||
|
audit them for GNU conformance. then document all your findings in a new
|
||||||
|
doc/conformance.txt file while perhaps implementing some of the missing
|
||||||
|
features.
|
||||||
|
you can find the latest POSIX documentation (1003.1-2008) here:
|
||||||
|
http://www.opengroup.org/onlinepubs/9699919799/
|
||||||
|
and the complete list of all utilities that POSIX covers:
|
||||||
|
http://www.opengroup.org/onlinepubs/9699919799/idx/utilities.html
|
||||||
|
The first step would to generate a file/matrix what is already archived
|
||||||
|
(also IPV6)
|
||||||
|
|
||||||
|
* implement 'at'
|
||||||
|
|
||||||
|
* rpcbind (former portmap) or equivalent
|
||||||
|
so that we don't have to use -o nolock on nfs mounts
|
||||||
|
|
||||||
|
* check IPV6 compliance
|
||||||
|
|
||||||
|
* generate a mini example using kernel+busybox only (+libc) for example
|
||||||
|
|
||||||
|
* more support for advanced linux 2.6.x features, see: iotop
|
||||||
|
most likely there is more
