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 Library 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. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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) 19yy 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. + + <signature of Ty Coon>, 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 Library General +Public License instead of this License. diff --git a/util/mkelfImage/Makefile b/util/mkelfImage/Makefile new file mode 100644 index 0000000000..2100ed4cbe --- /dev/null +++ b/util/mkelfImage/Makefile @@ -0,0 +1,118 @@ +include Makefile.conf +VERSION:=2.7 +RELEASE_DATE:=27 March 2006 +PACKAGE:=mkelfImage + +# You can specify DESTDIR on the command line to do a add +# a prefix to the install so it doesn't really happen +# Useful for building binary packages +DESTDIR = +CWD:=$(shell pwd) +OBJDIR:=objdir + +pkgdatadir = $(datadir)/$(PACKAGE) +pkglibdir = $(libdir)/$(PACKAGE) +pkgincludedir = $(includedir)/$(PACKAGE) + +CPPFLAGS=-DVERSION='"$(VERSION)"' -DRELEASE_DATE='"$(RELEASE_DATE)"' -I include +HOST_CPPFLAGS=$(CPPFLAGS) +I386_CPPFLAGS=$(CPPFLAGS) -I arch/i386/include +IA64_CPPFLAGS=$(CPPFLAGS) -I arch/ia64/include + +GENERATED_SRCS:=\ + ./configure \ + ./linux-i386/convert.bin.c\ + ./linux-ia64/convert.bin.c + +SPEC=$(OBJDIR)/mkelfImage-$(VERSION).spec +TARBALL=$(OBJDIR)/mkelfImage-$(VERSION).tar.gz +SRCS:=$(shell find ./AUTHORS ./COPYING ./Makefile ./Makefile.conf.in ./News \ + ./configure.ac \ + ./mkelfImage.spec.in \ + ./config \ + ./kunzip_src \ + ./main ./util ./include ./arch \ + ./linux-i386 \ + ./linux-ia64 \ + ! -path '*CVS*' ! -name '*~' ! -name '.*' -type f -print ) +SRCS+=$(GENERATED_SRCS) +PSRCS:=$(patsubst ./%,mkelfImage-$(VERSION)/%,$(SRCS)) +PSRCS+=./mkelfImage-$(VERSION).spec + +SBIN_TARGETS=$(OBJDIR)/sbin/mkelfImage +MAN8_TARGETS=$(OBJDIR)/man/man8/mkelfImage.8 + +TARGETS:=$(SBIN_TARGETS) $(MAN8_TARGETS) + +DEPS:= Makefile Makefile.conf +all: $(TARGETS) + +include main/Makefile +include util/Makefile +include linux-i386/Makefile +include linux-ia64/Makefile + + +clean:: + @$(RM) -rf objdir + @$(RM) -rf rpm + @$(RM) -f config.log config.status config.cache + @$(RM) -f $(SBIN_TARGETS) $(MAN1_TARGETS) + @$(RM) -f mkelfImage-$(VERSION) $(TARBALL) + +dist-clean:: clean + @$(FIND) . -type f -name '*~' | xargs $(RM) -f + @$(RM) Makefile.conf + +maintainer-clean:: dist-clean + @$(RM) -f $(SPEC) $(GENERATED_SRCS) + + +install: $(TARGETS) + $(MKDIR) -p $(DESTDIR)/$(pkgdatadir)/elf32-i386/ $(DESTDIR)/$(sbindir) $(DESTDIR)/$(mandir)/man8 + $(CP) -ar $(SBIN_TARGETS) $(DESTDIR)/$(sbindir)/ + $(CP) -ar $(MAN8_TARGETS) $(DESTDIR)/$(mandir)/man8/ + + +#%.1 : %.pl Makefile +# mkdir -p $(@D) +# pod2man --date="$(RELEASE_DATE)" --release="$(VERSION)" $*.pl > $@ + + +tarball: $(TARBALL) + + +$(TARBALL): $(SRCS) $(SPEC) + $(MKDIR) -p $(OBJDIR) + $(RM) -f $(OBJDIR)/mkelfImage-$(VERSION) + $(LN) -s .. $(OBJDIR)/mkelfImage-$(VERSION) + (cd $(OBJDIR); $(TAR) -cf - $(PSRCS) | gzip -9) > $@ + +rpm: $(TARBALL) + $(MKDIR) -p $(OBJDIR)/RPM $(OBJDIR)/SRPM $(OBJDIR)/BUILD $(OBJDIR)/SPECS $(OBJDIR)/TMP + unset MAKEFLAGS MAKELEVEL; \ + $(RPM) -ta \ + --define '_rpmdir $(CWD)/$(OBJDIR)/RPM' \ + --define '_srcrpmdir $(CWD)/$(OBJDIR)/SRPM' \ + --define '_builddir $(CWD)/$(OBJDIR)/BUILD' \ + --define '_specdir $(CWD)/$(OBJDIR)/SPECS' \ + --define '_tmppath $(CWD)/$(OBJDIR)/TMP' \ + $(TARBALL) + +Makefile.conf: Makefile.conf.in configure + /bin/sh ./configure + + +configure: configure.ac + autoconf + $(RM) -rf autom4te.cache + +$(SPEC): mkelfImage.spec.in Makefile + $(SED) -e 's,^Version: $$,Version: $(VERSION),' $< > $@ + + +.PHONY: echo install realinstall + + +echo: + echo $(SRCS) diff --git a/util/mkelfImage/Makefile.conf.in b/util/mkelfImage/Makefile.conf.in new file mode 100644 index 0000000000..4645e44a36 --- /dev/null +++ b/util/mkelfImage/Makefile.conf.in @@ -0,0 +1,46 @@ +prefix=@prefix@ +exec_prefix=@exec_prefix@ + +bindir=@bindir@ +sbindir=@sbindir@ +libexecdir=@libexecdir@ +datadir=@datadir@ +sysconfdir=@sysconfdir@ +sharedstatedir=@sharedstatedir@ +localstatedir=@localstatedir@ +libdir=@libdir@ +infodir=@infodir@ +mandir=@mandir@ +includedir=@includedir@ + +DEFS=@DEFS@ +LIBS=@LIBS@ +HOST_CC=@HOST_CC@ +HOST_CFLAGS=@HOST_CFLAGS@ $(DEFS) + +I386_CC =@I386_CC@ +I386_LD =@I386_LD@ +I386_AS =@I386_AS@ +I386_CPP =@I386_CPP@ +I386_OBJCOPY=@I386_OBJCOPY@ +I386_CFLAGS =@I386_CFLAGS@ +I386_ASFLAGS=@I386_ASFLAGS@ +I386_LDFLAGS=@I386_LDFLAGS@ + +IA64_CC =@IA64_CC@ +IA64_LD =@IA64_LD@ +IA64_AS =@IA64_AS@ +IA64_CPP =@IA64_CPP@ +IA64_OBJCOPY=@IA64_OBJCOPY@ +IA64_CFLAGS =@IA64_CFLAGS@ +IA64_ASFLAGS=@IA64_ASFLAGS@ +IA64_LDFLAGS=@IA64_LDFLAGS@ + +MKDIR=@MKDIR@ +RM=@RM@ +CP=@CP@ +LN=@LN@ +TAR=@TAR@ +RPM=@RPM@ +SED=@SED@ +FIND=@FIND@ diff --git a/util/mkelfImage/News b/util/mkelfImage/News new file mode 100644 index 0000000000..fbf8b6ace2 --- /dev/null +++ b/util/mkelfImage/News @@ -0,0 +1,123 @@ +* 2.6 14 March 2006 +- Fix the i386-linux probe code so it does not get confused by + bzImages that are also ELF executables. +- Changed value of GDTLOC and REAL_MODE_DATA_LOC to be below + 512kb.

The compression + method searches for as much of the current string of bytes (up to a + length of 258) in the previous 32 K bytes. If it doesn't find any + matches (of at least length 3), it codes the next byte. Otherwise, it + codes the length of the matched string and its distance backwards from + the current position. There is a single Huffman code that codes both + single bytes (called "literals") and match lengths. A second Huffman + code codes the distance information, which follows a length code. Each + length or distance code actually represents a base value and a number + of "extra" (sometimes zero) bits to get to add to the base value. At + the end of each deflated block is a special end-of-block (EOB) literal/ + length code. The decoding process is basically: get a literal/length + code; if EOB then done; if a literal, emit the decoded byte; if a + length then get the distance and emit the referred-to bytes from the + sliding window of previously emitted data. + + There are (currently) three kinds of inflate blocks: stored, fixed, and + dynamic. The compressor deals with some chunk of data at a time, and + decides which method to use on a chunk-by-chunk basis. A chunk might + typically be 32 K or 64 K. If the chunk is incompressible, then the + "stored" method is used. In this case, the bytes are simply stored as + is, eight bits per byte, with none of the above coding. The bytes are + preceded by a count, since there is no longer an EOB code. + + If the data is compressible, then either the fixed or dynamic methods + are used. In the dynamic method, the compressed data is preceded by + an encoding of the literal/length and distance Huffman codes that are + to be used to decode this block. The representation is itself Huffman + coded, and so is preceded by a description of that code. These code + descriptions take up a little space, and so for small blocks, there is + a predefined set of codes, called the fixed codes. The fixed method is + used if the block codes up smaller that way (usually for quite small + chunks), otherwise the dynamic method is used. In the latter case, the + codes are customized to the probabilities in the current block, and so + can code it much better than the pre-determined fixed codes. + + The Huffman codes themselves are decoded using a multi-level table + lookup, in order to maximize the speed of decoding plus the speed of + building the decoding tables. See the comments below that precede the + lbits and dbits tuning parameters. + */ + + +/* + Notes beyond the 1.93a appnote.txt: + + 1. Distance pointers never point before the beginning of the output + stream. + 2. Distance pointers can point back across blocks, up to 32k away. + 3. There is an implied maximum of 7 bits for the bit length table and + 15 bits for the actual data. + 4. If only one code exists, then it is encoded using one bit. (Zero + would be more efficient, but perhaps a little confusing.) If two + codes exist, they are coded using one bit each (0 and 1). + 5. There is no way of sending zero distance codes--a dummy must be + sent if there are none. (History: a pre 2.0 version of PKZIP would + store blocks with no distance codes, but this was discovered to be + too harsh a criterion.) Valid only for 1.93a. 2.04c does allow + zero distance codes, which is sent as one code of zero bits in + length. + 6. There are up to 286 literal/length codes. Code 256 represents the + end-of-block. Note however that the static length tree defines + 288 codes just to fill out the Huffman codes. Codes 286 and 287 + cannot be used though, since there is no length base or extra bits + defined for them. Similarly, there are up to 30 distance codes. + However, static trees define 32 codes (all 5 bits) to fill out the + Huffman codes, but the last two had better not show up in the data. + 7. Unzip can check dynamic Huffman blocks for complete code sets. + The exception is that a single code would not be complete (see #4). + 8. The five bits following the block type is really the number of + literal codes sent minus 257. + 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits + (1+6+6). Therefore, to output three times the length, you output + three codes (1+1+1), whereas to output four times the same length, + you only need two codes (1+3). Hmm. + 10.
