This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Here is a another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. upslug2-11/Makefile.am0000644000175000017500000000036010336520021011642 00000000000000sbin_PROGRAMS = upslug2 upslug2_SOURCES = linux_wire.cc pcap_wire.cc nslu2_image.cc nslu2_upgrade.cc upslug2.cc \ nslu2_image.h nslu2_protocol.h nslu2_upgrade.h upslug2_progress.h upslug2_LDADD = $(LIBPCAP_LIBS) EXTRA_DIST = README.macosx upslug2-11/Makefile.in0000644000175000017500000004415610336520063011674 00000000000000# Makefile.in generated by automake 1.9.6 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = . am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd INSTALL = @INSTALL@ install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ sbin_PROGRAMS = upslug2$(EXEEXT) DIST_COMMON = README $(am__configure_deps) $(srcdir)/Makefile.am \ $(srcdir)/Makefile.in $(srcdir)/config.h.in \ $(top_srcdir)/configure AUTHORS COPYING ChangeLog INSTALL NEWS \ config.guess config.sub depcomp install-sh missing subdir = .

Unlike upslug and the LinkSys (Sercomm) upgrade utilities upslug2 will synthesise a complete 'image' from a kernel and a root file system, as such it duplicates part of the functionality of 'slugimage'. upslug2 also optimises the upload to avoid transmitted parts of the image which need not be written or are 'blank' (set to the erased flash value of all 1's). upslug2 is functionally similar to upslug, however it is not derived from upslug. It is a rewrite ab initio based on the following information: 1) Observation of the behaviour of upslug and of the problems upslug has with the NSLU2 upgrade protocol. 2) Reverse engineering of that protocol for the purpose of writing a better upslug. 3) Examination (but not copying or direct use) of the GPL source code released by LinkSys and to be currently found at ftp://ftp.linksys.com/opensourcecode/nslu2/ upslug2-11/README.macosx0000644000175000017500000000172410335035601011770 00000000000000Starting with version 10 upslug2 is compatible with Mac OSX. Upslug2 requires libpcap version 0.9.3 or greater to work on OSX. By default, libpcap is included in OSX but it doesn't support all needed functions. So you will need to install a more recent version of libpcap. Fortunately the library is available through DarwinPorts (http://www.darwinports.org). Maybe it is also available from Fink (http://fink.sourceforge.net) but that has not been tested. If you don't have DarwinPorts installed, go to the website and learn how to use it. Just make sure you also install libpcap. Now you are ready to build upslug2: By default, DarwinPorts will be installed in /opt. If you have it installed in another location you have to adjust the path's below. CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib ./configure --with-libpcap make make install Using upslug2 requires root access since the bpf-device(s) on OSX are configured for read-only access for all other users. upslug2-11/aclocal.m40000644000175000017500000007546210336520061011471 00000000000000# generated automatically by aclocal 1.9.6 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. # Copyright (C) 2002, 2003, 2005 Free Software Foundation, Inc. # # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # AM_AUTOMAKE_VERSION(VERSION) # ---------------------------- # Automake X.Y traces this macro to ensure aclocal.m4 has been # generated from the m4 files accompanying Automake X.Y.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

The values in the packet are little endian - least significant * byte first. * * Each protocol packet is acknowledged by the NSLU2, sometimes by * simply returning the original packet with the first couple of bytes * modified to an error code, sometimes (in the case of HardwareInfo) * by returning a new packet with the requested information. * * BYTES 0,1 TYPE * The first two bytes in the data packet describe the contents of * the rest of the packet and what to do with them. * * HardwareInfo Return a description of hardware and firmware * UpgradeStart Start an upgrade * UpgradeData Download a block of new data * Reboot Reboot the NSLU2 * UpgradeVerify Verify a block of data ('upgrade' data only) * ReprogramStart Start a complete reflash (Reboot too) * * BYTES 2,3 SEQUENCE * The next two bytes give a little endian sequence number, the protocol * requires packets of data (UpgradeData and UpgradeVerify) to have * sequence numbers incremented by one between each packet. The initial * sequence number is set by the UpgradeStart or ReprogramStart packet. * Verification and Upgrade commands may not be intermixed - Verify must * follow upgrade - because the first UpgradeData erases the flash and * the first Verify resets the 'erase' state to 'erase on next UpgradeData'. * * BYTES 4,5 and 6,7 ADDRESS * Next comes the address. This is relevant only for UpgradeData and * UpgradeVerify. The address is an offset within a 1MByte block stored * as a byte offset within a 16 byte chunk plus a chunk offset. Both * offsets are 16 bit values, therefore the scheme can only address * (about) 1MByte. When the NSLU2 receives a 0 address it increments * it's internal 1MByte block counter. This is set to (-1) by both * UpgradeStart and ReprogramStart and on the first UpgradeVerify. * Consequently the first UpgradeData or UpgradeVerify must have an * address of 0 (to cause the block number to be incremented to 0). * * BYTES 4,5: byte offset * BYTES 6,7: 16 byte chunk * * BYTES 8,9 LENGTH * The data length is stored next - this is the number of bytes of data * which follows. The actual protocol code in the NSLU2 defines 600 * bytes for this, however the buffer is allocated by the stock RedBoot * ethernet code and this seems to be set up to handle a maximum data * length of an ethernet packet (1500 bytes) correctly. * * Nevertheless of safety, and just in case something on the wire limits * the packet size further, this code sends 512 bytes of data at a time; * so the maximum data size (including the header) is 522 bytes. * *----------------------------------------------------------------------------- * Protocol definitions. *----------------------------------------------------------------------------- * In practice the RedBoot implementation does not re-allocate the buffer * before returning the packet, therefore whatever the value of the LENGTH * field in the packet, the packet must be long enough to also accomodate the * return data.
