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/ChangeLog b/ChangeLog new file mode 100644 index 0000000..b229b55 --- /dev/null +++ b/ChangeLog @@ -0,0 +1,677 @@ +2018-02-05, iucode_tool v2.3.1 + * iucode_tool: fix filter by revision parser on ILP32 + +2018-01-28, iucode_tool v2.3 + + * iucode_tool(8): document changes to ucode filtering + * iucode_tool: support selecting by ucode revision + Add a third (and optional) parameter to microcode selection filters, to + select microcodes by revision.

Also, print the value of these + variables in configure output. The standard methods to override the + default CFLAGS, CPPFLAGS and LDFLAGS in configure still work, and will + bypass the new defaults. Linux distros that override these on every build + should not see any changes. Should the compiler not be detected as + gcc-compatible, no change to CFLAGS/CPPFLAGS/LDFLAGS will be made. Note + that clang is explicitly supported, and works just fine. The build will + default to a baseline of "-O3 -g" and will attempt to selectively enable + several warning options, and several hardening options. configure will + attempt to detect the set of compiler and linker driver flags that would + work.

It is extremely unlikely that the + harmful misbehavior could be triggered by accident -- at least when + iucode_tool is linked to glibc -- due to glibc's memory allocator + implementation details. Also, it is not believed to be possible for + this bug to trigger in a harmful manner when only one datafile is + being processed. However, it might be possible for an attacker to + trigger the issue using a number of specially crafted data files, and + it might also require tricking the user into using a specially crafted + command line. Should the worst happen, iucode_tool may be convinced + to corrupt its heap, and possibly the libc's heap control data + structures, which could result in code execution, depending on the + libc's internals. The harmless version of this bug is trivially + triggered by using the -tr (recovery) loader on any file that ends + with a valid microcode, such as any file that only contains valid + microcode.

We control the size of this "padding" entry + by the length of its name, without any embedded NULs hacks. The + increase in cpio metadata size caused by an extra cpio member header + entry is always going to be absorbed by the padding at the end of the + cpio archive at a 512 byte or 1024 byte block size: the file size of + the resulting early initramfs is not changed. For --mini-earlyfs + mode, which is tailored to what the kernel cares about and minimal + size, we use the older workaround which results in a smaller archive + at a 16-byte block size. + * iucode_tool: cosmetic error path cleanup for write_cpio_header() + * iucode_tool(8): document --mini-earlyfw and --normal-earlyfw + * iucode_tool: add command line option to minimize early initramfs size + A minimized early initramfs has a block size of 16 bytes, and doesn't + contain parent directories. + * iucode_tool: prepare for early-initramfs size minimization + Enhance the low-level cpio header/trailer output functions to take + runtime parameters instead of compile-time constants for: cpio block + size and whether to include parent directories.

For --write-named-to, --write-all-named-to, and + --write-firmware, also fsync() the parent directory after all files + have been written. These changes cause a severe performance + degradation, but without them we cannot detect write errors on close, + and that can end up corrupting a file important for system boot since + the write error would be undetectable to a shell script. + * configure.ac: default to dist-xz and enable warnings + Enable automake warnings, and switch the "make dist" target to xz + compression, as that's what is being used for the signed release + tarballs. + * configure.ac: update autotools minimum versions + Update the minimum autoconf version to 2.69, and automake to 1.11. + Older versions are not supported, and might or might not work. + This is only relevant when not using the pre-built configure script + shipped in the iucode_tool distribution tarballs. + * iucode_tool: use print_warn() when we do not write to a file + When there is nothing to output to a file, we don't touch it (i.e. we + do not overwrite it with an empty result).

This is vastly more useful than a monotonically + increasing number that is not usable anywhere else. + * iucode_tool: demote debug output about bundle assignment + Now that we will output bundle assignment messages for --list (and not + just --list-all), demote status/debug output about bundle assignment, + so that it matches the same verbosity level of other messages from the + same function.

The refactored code sorts the uclist by cpuid (ascending + order) and pf_mask (descending order), which stabilizes the sorting + order. The pf_masks are sorted in descending order to ensure it will + find supersets first as it walks the list. Downgrade mode is (still) + limited by not being able to change pf_masks, so partially + "superseded" (in the downgrade mode sense) entries will be left over + in the selected microcode list when unavoidable. + +2016-06-04, iucode_tool v1.6.1 + + * iucode_tool: append microcode bundles to linked list in O(1) + * iucode_tool: stop allocating twice the required memory for a bundle + * iucode_tool: don't close input files twice + load_intel_microcode() would cause fds to be closed twice. iucode_tool + is not multi-threaded and isn't otherwise affected by this bug, but + unfortunately there is a free() call between the first and second + close().

This + ensures "valgrind --leak-check=full --show-leak-kinds=all" output has no + known false positives. For non-valgrind builds, we simply don't bother to + free any heap memory in the exit path, as it would be just a waste of CPU + cycles. + * iucode_tool: look harder for superseded entries + When we replace an entry that has the same pf_mask, it is necessary to + look for entries that became obsolete. In non-downgrade mode, we might + have skipped a few revisions, and might have merged microcode that is a + proper subset, but has an intermediary revision between ours and the + one we're replacing. In downgrade mode, the revision doesn't matter so + it is even easier to have proper subset entries around that became + obsolete. + * iucode_tool: discard late outdated merge for loose date filter + When in downgrade mode, during the second pass of the loose date + filter, we would merge microcode that is a proper subset (and has the + same revision) of already merged microcode. This is harmless, but it + would waste space in the output. It is unlikely that this bug would + ever happen with real microcode updates. + * iucode_tool: fix downgrade mode when loose date-filtering + Downgrade mode was broken for the loose mode of date filtering. Due to + this bug, a microcode selected by the loose date filter might be + preferred over one that was loaded later. + * iucode_tool: fix infinite loop bug on non-disjoint pf_masks + In the specific case where two microcodes for the same CPU signature + had non-disjoint pf_masks, and neither pf_mask was contained in the + other, the code would loop forever when it attempted to add the second + microcode to the list of selected microcodes. Fortunately, Intel never + published a public microcode update that could trigger this codepath. + This issue exists in every released version of iucode_tool to date. + * iucode_tool: cosmetic changes to load_intel_microcode() + * iucode_tool: make uclist_add_signature() slightly faster + Change uclist_add_signature() to stop looking for duplicates at the + first match. This is slightly faster when processing several files + with many duplicates, but it changes same-sig same-revision internal + ordering from earliest first to latest first. This change to the + sorting order only change the order in which do_write_named() will + create the per-microcode data files. Also, trigger microcode opaque + data comparison on the pointer to the duplicate being non-NULL, instead + of testing for res == EEXIST. Note that this is not fixing an existing + bug, the old code was correct. + * iucode_tool: cosmetic fixes for uclist_add_signature() + +2015-10-16, iucode_tool v1.5 + + * New --write-all-named-to option: + + iucode_tool(8): document the new --write-all-named-to option. + + iucode_tool: add a --write-all-named-to option, which works like + --write-named-to, but instead of operating on selected microcode, it + operates on every revision of every microcode. Exact duplicates are + skipped, keyed on INTEL_UCLE_DUPSIG. This avoids the need to always + enable --overwrite mode. This is the only way to write out every + revision of a microcode. + + iucode_tool: add a new flag, INTEL_UCLE_DUPSIG, and use it to track + duplicate signatures when they are added to all_microcodes. Only the + first copy of that exact microcode (signature+pfm+revision) will not + have INTEL_UCLE_DUPSIG set, in *load* order, regardless of downgrade + mode. + * intel_microcode.c: remove lots of unlikely() use, as the premise that + it is most often called on valid microcode is no longer valid due to + the recovery loader. + * iucode_tool(8): fix parameter of --write-named-to. The manpage text + was incorrectly naming the parameter of the option --write-named-to to + be a file. It is a directory, as documented for the short version of + the same option (-W). + * iucode_tool(8): add two examples for the recovery loader (-tr): how to + use it to load microcode from an early initramfs, and also how to use + it to update an Arch-linux style separate early initramfs. + * Changelog: correct the indentation of older Changelog entries. + * Changelog: switch back to a "raw" changelog style.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + 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 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. + + Running `configure' might take a while. 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. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +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=c99 CFLAGS=-g 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 can use 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 `..'. + + With a non-GNU `make', it is safer 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). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/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. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..415a241 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,10 @@ +## +## Toplevel Makefile.am for iucode_tool +## + +sbin_PROGRAMS = iucode_tool +man_MANS = iucode_tool.8 + +iucode_tool_SOURCES = intel_microcode.h intel_microcode.c iucode_tool.c +EXTRA_DIST = autogen.sh CONTRIBUTING + diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..1f9cd8c --- /dev/null +++ b/Makefile.in @@ -0,0 +1,853 @@ +# Makefile.in generated by automake 1.15 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2014 Free Software Foundation, Inc. + +# This Makefile.in is free software;

These +microcode updates correct processor errata, and are often important for +safe, correct system operation. + +While most of the microcode updates fix problems that either happen rarely +or are related to less commonly used features, there are enough updates +fixing issues that would cause system lockup, memory corruption, and +unpredictable system behavior, to warrant taking it seriously. + +Microcode updates are ephemeral: they will be lost after a system processor +hard reset or when the processor is powered off. They must be reapplied at +every boot and after the system wakes up from suspend to RAM or to disk. + +Updating the system processor microcode is the responsibility of the system +firmware (BIOS or EFI). However, not all vendors will release timely +updates for their firmware when Intel releases updated microcode, and most +users don't update their system firmware in a timely fashion (or at all) +anyway. + +The end result is that, unless some other method of distributing microcode +updates is in place, the processor in many systems will be running with +outdated microcode, increasing the chances of incorrect system operation. + +Intel has made available to the general public a microcode update data file +(microcode bundle), which the operating system can use to install microcode +updates independently from any system firmware updates. Currently, the +same data file (microcode bundle) is used to distribute microcode updates +for all Intel i686 and X86_64 processor models. + + +Updating the system processor microcode: + +The Intel-distributed microcode bundle contains microcode update data for +several processor models. Older microcode releases used a text format +which is unsuitable to be used directly by the Linux kernel: it must be +converted by an utility like iucode_tool before Linux can use it. Newer +releases have the same microcode update content both in the legacy text +format, and in binary format. + +Updating the processor microcode is a process that can be done at any time +(even with the system at full load), and as many times as required. It is +strongly recommended that microcode updates be applied during early system +boot, though: + + * Microcode updates should be applied as soon as possible to + shorten the time window where the errata fixed by the update + could still trigger; + + * Some microcode updates can only be applied safely before the + operating system enables more advanced processor functionality, + otherwise that functionality must be disabled by the kernel + (Atom PSE erratum); + + * Some microcode updates disable (faulty) functionality or make + other "visible" changes to the processor, and must be applied + before either the kernel or applications start using that + functionality (e.g. Haswell Intel TSX erratum). + +Therefore, one should always apply microcode updates through firmware +(BIOS/EFI) updates when possible. Failing that, one should use the "early +initramfs" and "early microcode update driver" support in Linux v3.9 and +later. As a last option, one can use the "late microcode update" driver, +but this one might run too late to be of any help (and it cannot safely +apply microcode updates such as the Intel Haswell TSX fix). + + +To apply a microcode update using the early microcode kernel driver: + + 1. Arrange for iucode_tool --write-earlyfw to generate the early + initramfs image from microcode data files. You probably want + to also use --scan-system to reduce the size of the generated + early initramfs image; + + 2. Either prepend the earlyfw image generated by iucode_tool to + the initramfs, or, if your bootloader can handle it, arrange + for it to load the early initramfs and the standard initramfs + images in sequence; + + 3. Boot the system using a suitable Linux v3.9 or later kernel, + compiled with kconfig options CONFIG_MICROCODE_EARLY=y and + CONFIG_MICROCODE_INTEL_EARLY=y. + + 4. Ensure the late microcode update driver (microcode module) is + either loaded or compiled in (CONFIG_MICROCODE=y), as it will + be needed if the microcode needs to be reapplied to a processor, + e.g. due to a suspend/resume or hibernate/resume cycle, or due + to CPU hotplug. + +This is usually handled by the Linux distro when you install microcode +update support packages. Check your distro's documentation for details. + + +To apply a microcode update for an Intel system processor after the Linux +kernel boots, using the late microcode update driver (warning: this can +render the system unusable if it applies a microcode update that disables +processor features): + + ***** WARNING ***** the method below is unsafe ***** WARNING ***** + + 1. Place the binary microcode in /lib/firmware/ with the correct + file name (iucode_tool -K can do this automatically for Intel + microcode); + + 2.

The proper way to do this is +distro-specific. + +If your distro has no use for the .dat file after you installed updated +binary files to /lib/firmware, you can remove it to save some space. + + +About the Intel-supplied microcode updates file: + +Unfortunately, as of November 2014, Intel still does not usually publish +any information about changes to the intel-microcode.dat distribution to +the general public. Such information may be available through restricted +developer and partner channels, though. Very rarely, a specification +update might carry some information about the errata fixed by the latest +microcode revision. + +Intel removes microcode from their public distribution regularly. One can +theorize that removals of microcode updates for very old processors that +were distributed over a reasonable number of microcode data file releases +were done to reduce bundle file growth. Unfortunately, such removals could +cause unnecessary regressions on very old, but still operational hardware, +so distros used on older hardware might want to still ship them. + +On recent processors, Intel microcode release management can be puzzling: +Intel has often removed from the distribution microcode for recent +processors, as well as microcode that it had recently issued updates for. +Microcode version downgrades have also been observed. + +We can only hope that Intel will start publishing microcode update +changelog information to the general public in the future. This would +certainly make it easier for distros to schedule microcode updates for +their stable branches. + + + + Technical details (optional reading) + + +Intel Microcode signatures: + +Intel system processor microcode is identified by the processor signature +(a 32-bit number) and by three bits called "processor flags". The +Microcode is often, but not always, the same among several processors that +differ only on their processor flags, and have the same processor +signature. + +These signatures are useful when one wants to look for entries referring to +a specific processor in documentation, or request that iucode_tool create +microcode binary bundles for a specific set of processors. Otherwise, you +can just ignore them as they are handled automatically by iucode_tool and +by the kernel microcode driver. + +If you want to know the signature of the processors in your system, run +"iucode_tool --scan-system". It is possible for a multiprocessor system +to contain processors with different signatures (known as mixed stepping +configurations), although this is usually not an ideal configuration. + +The processor signature is returned in the EAX register from leaf 1 of the +CPUID instruction. It contains an encoded format of the CPU stepping, +model, family and type, and a few undefined (reserved) bits that are zero +on all current Intel processors. + + +Listing what is inside a microcode bundle: + +The microcode signatures for each microcode available in a microcode bundle +can be listed by iucode_tool: + +iucode_tool -L /usr/share/misc/intel-microcode.dat + +microcode bundle 1: /usr/share/misc/intel-microcode.dat + 001/001: sig 0x00000683, pf_mask 0x01, 2001-02-06, rev 0x0013, size 2048 + 001/002: sig 0x00000f4a, pf_mask 0x5c, 2005-12-14, rev 0x0004, size 2048 + 001/003: sig 0x00000653, pf_mask 0x04, 1999-05-20, rev 0x000b, size 2048 + ... + +The first and third microcode updates are for very specific processor +models (a single combination of processor flags, each, as they only have +one bit set in the pf_mask field). The second microcode update applies to +several processors that share the same family, model and stepping, but have +different processor flags (more than one bit set in the pf_mask field). The +processor flags and pf_mask field are explained below. + +iucode_tool -L s000406A8_m00000001_r0000081F.fw + +microcode bundle 1: s000406A8_m00000001_r0000081F.fw + 001/001: sig 0x000406a8, pf_mask 0x01, 2014-08-12, rev 0x081f, size 38912 + sig 0x000406a8, pf_mask 0x01, 2014-08-12, rev 0x081f + sig 0x000406a9, pf_mask 0x01, 2014-08-12, rev 0x081f + +This is a microcode update with multiple signatures. At least one of the +signatures will typically be a duplicate. iucode_tool will act on each +signature (list, select, etc) as if they were independent, but when writing +out the microcode, all of its signatures will be included. It will not +output more than a single copy of the microcode to the same output file. + + +Microcode revisions: + +Microcode revisions are signed 32-bit integers. Negative revisions are +used by Intel during microcode and chip development, and will not be found +on public microcode updates: you'd usually find such microcode only in +UEFI/BIOS images, to support Engineering Sample processors. + +Revision 0 is used by the system processor to signal that it is running the +factory-provided microcode (i.e. no microcode updates were installed). No +Intel processor to date (since the Pentium Pro) is supposed to run with +factory (revision 0) microcode: a lot of functionality will be either +extremely buggy or missing entirely. + +iucode_tool will list negative revisions as a large unsigned number. +However, it will prefer positive revisions over negative revisions when +selecting microcode. + +microcode bundle 1: coreboot/s00040650_m00000072_rFFFF000A.fw + 01/001: sig 0x00040650, pf_mask 0x72, 2012-11-09, rev 0xffff000a, size 22528 + +The release dates are useful to track how old a microcode update is, but +are otherwise ignored by the kernel driver: Intel documentation clearly +states that only the revision number should be used to decide which +microcode update is more recent. + + +Microcode processor flags mask (pf_mask): + +Some Intel processor variants may share the same processor signature, and +yet require different microcode.

E.g. if bit 6 is set, that +microcode can be applied to a processor with the appropriate signature and +the processor flags combination 110 (in binary). + +A microcode update identified by a processor flags mask of 42 (hexadecimal) +would apply to two types of processors: those with processor flags +combination 001 (binary), and also those with processor flags combination +110 (binary). + +The definition of what a processor flag combination means varies with the +processor model. + +Some very old processors lack processor flags support.

Duplicated and outdated +microcodes will be discarded. It can read microcode data from standard +input (\fIstdin\fP), by specifying a file name of \(lq\-\(rq (minus sign). +.PP +Microcode data files are assumed to be in .dat text format if they have a .dat +suffix, and to be in binary format otherwise. Standard input (\fIstdin\fP) is +assumed to be in .dat text format. The \fI\-t\fP option can be used to change +the type of the files specified after it, including for \fIstdin\fP. +.PP +If a directory is specified, all files whose names do not begin with a +dot will be loaded, in unspecified order. Nested directories are skipped. +.PP +Empty files and directories are ignored, and will be skipped. +.PP +You can select which microcodes should be written out, listed or uploaded +to the kernel using the +.IR "\-S" ", " "\-s" ", " "\-\-date\-before" " and " "\-\-date\-after" +options. Should none of those options be specified, all microcodes will be +selected. +.PP +You can upload the selected microcodes to the kernel, write them out to +a file (in binary format), to a Linux early initramfs archive, to +per-processor-signature files in a directory, or to per-microcode files +in a directory using the +.IR "\-w" ", " +.IR "\-\-write\-earlyfw" ", " +.IR "\-k" ", " +.IR "\-K" ", and " +.IR "\-W" " options." +.PP +\fBiucode_tool\fP will identify microcodes in its output and error messages +using a \(lq\fIn/k\fP\(rq notation, where \(lq\fIn\fP\(rq is the bundle +number, and \(lq\fIk\fP\(rq is the microcode number within that bundle. The +output of the +.IR "\-\-list\-all" " option" +when processing multiple input files is the best example of how it works. + +.PP +For more information about Intel processor microcodes, please read the +included documentation and the Intel manuals listed in the \fISEE ALSO\fP +section. + +.SH OPTIONS +\fBiucode_tool\fP accepts the following options: + +.TP +.BR \-q ", " \-\-quiet +Inhibit usual output. +.TP +.BR \-v ", " \-\-verbose +Print more information.

The two drivers were +unified in Linux v4.4. + +The microcode update driver needs to be present in the system at all times +to ensure microcode updates are reapplied on resume from suspend and CPU +hotplug. Do not unload the microcode module, unless you really know +better. Since Linux v4.4, the late microcode driver cannot be a module +anymore and will always be present in the system when enabled. + +Updating microcode early is safer. It can only be done at boot and it +requires an initramfs, but it is strongly recommended: late microcode +updates (which read microcode data from /lib/firmware) cannot safely change +visible processor features. + +Early microcode updates are available since Linux v3.9. They can safely +change visible processor features (such as the microcode updates that +disabled Intel TSX instructions on Intel Haswell cores do). They require +an uncompressed initramfs image with the microcode update data in +\fI/kernel/x86/microcode/GenuineIntel.bin\fP. This uncompressed initramfs +image must come before any compressed initramfs image(s), and it has an +special name: \fIearly initramfs\fP. + +The microcode update data inside the early initramfs image must be aligned +to a 16-byte boundary due to a bug in several versions of the Linux kernel +early microcode update driver. This requires special steps when creating +the initramfs archive with the microcode data, and will be handled +automatically by the \fBiucode_tool\fP \fI\-\-write\-earlyfw\fP option. + +Since Linux v4.2, it is also possible to build a kernel with the microcode +update data as built-in firmware, using the CONFIG_FIRMWARE_IN_KERNEL +facility. This feature is not yet mature as of Linux v4.2.8, v4.4.11, +v4.5.5 and v4.6, and might not work in every case. + +The \fI/dev/cpu/microcode\fP update interface has been deprecated and +should not be used. It has one special requirement: each write syscall +must contain whole microcode(s).

Depending +on kernel version, you must either trigger it on every core to avoid a +dangerous situation where some cores are using outdated microcode, or the +kernel will accept the request only for the boot processor and use it to +trigger an update on all system processor cores. + +Since Linux v3.6, the late microcode update driver has a new interface +that explicitly triggers an update for every core at once when the number +1 is written to \fI/sys/devices/system/cpu/microcode/reload\fP. + +.SH EXAMPLES +.SS Updating files in \fI@MICROCODE_DIR_DEFAULT@\fP: +.HP +iucode_tool \-K@MICROCODE_DIR_DEFAULT@ \\ +.br + @MICROCODE_DIR_DEFAULT@ \\ +.br + /tmp/file\-with\-new\-microcodes.bin +.SS Processing several compressed files at once: +.HP +zcat intel\-microcode*.dat.gz | iucode_tool\ \-l\ \- +.HP +zcat intel\-microcode*.bin.gz | iucode_tool \-l\ \-tb\ \- +.SS Selecting microcodes and creating an early initramfs: +.HP +iucode_tool \-\-scan\-system \\ +.br + \-\-write\-earlyfw=/tmp/early.cpio \\ +.br + /lib/firmware/intel\-ucode +.HP +iucode_tool \-s\ 0x106a5 \-s\ 0x106a4 \-l /lib/firmware/intel\-ucode +.SS Using the recovery loader to load and to update microcode in an early initramfs: +.HP +iucode_tool \-L \-tr /boot/intel\-ucode.img +.HP +iucode_tool \-Ll \-S \-\-write\-earlyfw=/boot/intel\-ucode.img.new \\ +.br + \-tr /boot/intel\-ucode.img \-tb /lib/firmware/intel\-ucode && \\ +.br +mv /boot/intel\-ucode.img.new /boot/intel\-ucode.img + +.SH BUGS +Microcode with negative revision numbers is not special-cased, and will not be +preferred over regular microcode. + +.PP +The \fIdowngrade mode\fP should be used only for microcodes with the same +\fIprocessor flags mask\fP.
