By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +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. + + + Copyright (C) + + 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 Street, 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. + + , 1 April 1989 + Ty Coon, President of Vice + +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 Lesser General +Public License instead of this License. diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..77c9310 --- /dev/null +++ b/Makefile @@ -0,0 +1,144 @@ +# +# DMI Decode +# BIOS Decode +# VPD Decode +# +# Copyright (C) 2000-2002 Alan Cox +# Copyright (C) 2002-2015 Jean Delvare +# +# 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. +# + +CC = gcc +CFLAGS = -W -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual \ + -Wcast-align -Wwrite-strings -Wmissing-prototypes -Winline -Wundef + +# Let lseek and mmap support 64-bit wide offsets +CFLAGS += -D_FILE_OFFSET_BITS=64 + +#CFLAGS += -DBIGENDIAN +#CFLAGS += -DALIGNMENT_WORKAROUND + +# When debugging, disable -O2 and enable -g. +CFLAGS += -O2 +#CFLAGS += -g + +# Pass linker flags here +LDFLAGS = + +DESTDIR = +prefix = /usr/local +sbindir = $(prefix)/sbin +mandir = $(prefix)/share/man +man8dir = $(mandir)/man8 +docdir = $(prefix)/share/doc/dmidecode + +INSTALL := install +INSTALL_DATA := $(INSTALL) -m 644 +INSTALL_DIR := $(INSTALL) -m 755 -d +INSTALL_PROGRAM := $(INSTALL) -m 755 +RM := rm -f + +# BSD make provides $MACHINE, but GNU make doesn't +MACHINE ?= $(shell uname -m 2>/dev/null) + +# These programs are only useful on x86 +PROGRAMS-i386 := biosdecode ownership vpddecode +PROGRAMS-i486 := $(PROGRAMS-i386) +PROGRAMS-i586 := $(PROGRAMS-i386) +PROGRAMS-i686 := $(PROGRAMS-i386) +PROGRAMS-x86_64 := biosdecode ownership vpddecode +PROGRAMS-amd64 := $(PROGRAMS-x86_64) + +PROGRAMS := dmidecode $(PROGRAMS-$(MACHINE)) + +all : $(PROGRAMS) + +# +# Programs +# + +dmidecode : dmidecode.o dmiopt.o dmioem.o util.o + $(CC) $(LDFLAGS) dmidecode.o dmiopt.o dmioem.o util.o -o $@ + +biosdecode : biosdecode.o util.o + $(CC) $(LDFLAGS) biosdecode.o util.o -o $@ + +ownership : ownership.o util.o + $(CC) $(LDFLAGS) ownership.o util.o -o $@ + +vpddecode : vpddecode.o vpdopt.o util.o + $(CC) $(LDFLAGS) vpddecode.o vpdopt.o util.o -o $@ + +# +# Objects +# + +dmidecode.o : dmidecode.c version.h types.h util.h config.h dmidecode.h \ + dmiopt.h dmioem.h + $(CC) $(CFLAGS) -c $< -o $@ + +dmiopt.o : dmiopt.c config.h types.h util.h dmidecode.h dmiopt.h + $(CC) $(CFLAGS) -c $< -o $@ + +dmioem.o : dmioem.c types.h dmidecode.h dmioem.h + $(CC) $(CFLAGS) -c $< -o $@ + +biosdecode.o : biosdecode.c version.h types.h util.h config.h + $(CC) $(CFLAGS) -c $< -o $@ + +ownership.o : ownership.c version.h types.h util.h config.h + $(CC) $(CFLAGS) -c $< -o $@ + +vpddecode.o : vpddecode.c version.h types.h util.h config.h vpdopt.h + $(CC) $(CFLAGS) -c $< -o $@ + +vpdopt.o : vpdopt.c config.h util.h vpdopt.h + $(CC) $(CFLAGS) -c $< -o $@ + +util.o : util.c types.h util.h config.h + $(CC) $(CFLAGS) -c $< -o $@ + +# +# Commands +# + +strip : $(PROGRAMS) + strip $(PROGRAMS) + +install : install-bin install-man install-doc + +uninstall : uninstall-bin uninstall-man uninstall-doc + +install-bin : $(PROGRAMS) + $(INSTALL_DIR) $(DESTDIR)$(sbindir) + for program in $(PROGRAMS) ; do \ + $(INSTALL_PROGRAM) $$program $(DESTDIR)$(sbindir) ; done + +uninstall-bin : + for program in $(PROGRAMS) ; do \ + $(RM) $(DESTDIR)$(sbindir)/$$program ; done + +install-man : + $(INSTALL_DIR) $(DESTDIR)$(man8dir) + for program in $(PROGRAMS) ; do \ + $(INSTALL_DATA) man/$$program.8 $(DESTDIR)$(man8dir) ; done + +uninstall-man : + for program in $(PROGRAMS) ; do \ + $(RM) $(DESTDIR)$(man8dir)/$$program.8 ; done + +install-doc : + $(INSTALL_DIR) $(DESTDIR)$(docdir) + $(INSTALL_DATA) README $(DESTDIR)$(docdir) + $(INSTALL_DATA) NEWS $(DESTDIR)$(docdir) + $(INSTALL_DATA) AUTHORS $(DESTDIR)$(docdir) + +uninstall-doc : + $(RM) -r $(DESTDIR)$(docdir) + +clean : + $(RM) *.o $(PROGRAMS) core diff --git a/NEWS b/NEWS new file mode 100644 index 0000000..18b0325 --- /dev/null +++ b/NEWS @@ -0,0 +1,142 @@ +Version 3.2 (Wed Sep 14 2018) + - [COMPATIBILITY] The UUID is now displayed using lowercase letters, per + RFC 4122 (#53569).

Thus, one use of dmidecode is for kernel +developers to detect system "signatures" and add them to the kernel source +code when needed. + +Beware that DMI data have proven to be too unreliable to be blindly trusted. +Dmidecode does not scan your hardware, it only reports what the BIOS told it +to. + + +** INSTALLATION ** + +The home web page for dmidecode is hosted on Savannah: + http://www.nongnu.org/dmidecode/ +You will find the latest version (including CVS) there, as well as fresh news +and other interesting material, such as a list of related projects and +articles. + +This program was first written for Linux, and has since been reported to work +on FreeBSD, NetBSD, OpenBSD, BeOS and Solaris as well. + +There's no configure script, so simply run "make" to build dmidecode, and +"make install" to install it. You also can use "make uninstall" to remove +all the files you installed. By default, files are installed in /usr/local +but you can change this behavior by editing the Makefile file and setting +prefix to wherever you want. You may change the C compiler and the +compilation flags as well. + +Optionally, you can run "make strip" prior to "make install" if you want +smaller binaries. However, be aware that this will prevent any further +attempt to debug the programs. + +Two parameters can be set in the Makefile file to make dmidecode work on +non-i386 systems. They should be used if your system uses the big endian +byte ordering (Motorola) or doesn't support unaligned memory accesses, +respectively. For example, compiling for a SPARC processor would require +both (but I am not aware of SPARC-based systems implementing SMBIOS). +Compiling for an IA64 processor requires the memory alignment workaround, +and it is enabled automatically. + + +** DOCUMENTATION ** + +Each tool has a manual page, found in the "man" subdirectory. Manual pages +are installed by "make install". See these manual pages for command line +interface details and tool specific information. + +For an history of the changes made to dmidecode, see the NEWS file. + +If you need help, your best chances are to visit the web page (see the +INSTALLATION section above) or to get in touch with the developers directly. +Have a look at the AUTHORS file and contact one of the maintainers. + +If you want to help with the development of dmidecode, please consider +joining the dmidecode-devel discussion list: + http://lists.nongnu.org/mailman/listinfo/dmidecode-devel + + +** COMMON PROBLEMS ** + +IA-64 + +Non-Linux systems are not yet supported. + +MMAP + +Note that mmap() is now used by default wherever possible, since this seems +to solve a number of problems. This default behavior can be changed in +config.h. Just to make sure this is clear, mmap() is not used for performance +reasons but to increase the number of systems on which dmidecode can be +successfully run. + +CYGWIN + +Dmidecode used to work under Cygwin. However the /dev/mem interface was +removed at some point in time so it no longer works. + + +** MISCELLANEOUS TOOLS ** + +Three other tools come along with dmidecode: biosdecode, ownership and +vpddecode. These tools are only useful on systems with a BIOS, so they +are not built on IA-64 by default. + +BIOSDECODE + +This one prints all BIOS related information it can find in /dev/mem. +It used to be part of dmidecode itself, but as dmidecode was growing, +we felt that the non-DMI part had to be moved to a separate tool. + +OWNERSHIP + +This tool was written on a request by Luc Van de Velde for use with Novell +tools in his company. It retrieves the "ownership tag" that can be set on +most Compaq computers. Since it uses the same mechanisms dmidecode and +biosdecode use, and could be of some use for other people as well, we +decided to make it part of the project. + +VPDDECODE + +This tool prints the contents of the "vital product data" structure as +found in most IBM and Lenovo computers. It used to have a lookup table +for the machine name, but it was unreliable and hard to maintain so it +was ultimately dropped. It has a command line interface. diff --git a/biosdecode.c b/biosdecode.c new file mode 100644 index 0000000..99a27fe --- /dev/null +++ b/biosdecode.c @@ -0,0 +1,723 @@ +/* + * BIOS Decode + * + * Copyright (C) 2000-2002 Alan Cox + * Copyright (C) 2002-2017 Jean Delvare + * + * 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.
