Windows-only freeware GUI application written in C#. Used mostly for SLIC-related modifications, but it not limited to this task. Requires Microsoft .NET 3.5 to work properly. Supports unpacking firmware images from various vendor-specific formats like encrypted HP update files and Dell installers. +* **[uefi-firmware-parser](https://github.com/theopolis/uefi-firmware-parser)** by [Teddy Reed](https://github.com/theopolis). Cross-platform open source console application written in Python. Very tinker-friendly due to use of Python. Can be used in scripts to automate firmware patching. +* **[Chipsec](https://github.com/chipsec/chipsec)** by Intel. Cross-platform partially open source console application written in Python and C. Can be used to test Intel-based platforms for various security-related misconfigurations, but also has NVRAM parser and other components aimed to firmware modification. + +## Installation + +You can either use [pre-built binaries](https://github.com/LongSoft/UEFITool/releases) or build a binary yourself. +* To build a binary that uses Qt library (UEFITool) you need a C++ compiler and an instance of [Qt5 or Qt6](https://www.qt.io) library. Install both of them, get the sources, generate makefiles using qmake (`qmake ./UEFITool/uefitool.pro`) and use your system's make command on that generated files (i.e. `nmake release`, `make release` and so on). Qt6-based builds can also use CMAKE as an altearnative build system. +* To build a binary that doesn't use Qt (UEFIExtract, UEFIFind), you need a C++ compiler and [CMAKE](https://cmake.org) utility to generate a makefile for your OS and build environment. Install both of them, get the sources, generate makefiles using cmake (`cmake UEFIExtract`) and use your system's make command on that generated files (i.e. `nmake release`, `make release` and so on). Non-Qt builds can also use Meson as an alternative build system. + +## Known issues + +* Image editing is currently only possible using an outdated and unsupported UEFITool 0.28 (`old_engine` branch) and the tools based on it (`UEFIReplace`, `UEFIPatch`). This is the top priority [issue #67](https://github.com/LongSoft/UEFITool/issues/67), which is being worked on, albeit slowly (due to the amount of coding and testing required to implement it correctly). +* Some vendor-specific firmware update files can be opened incorrectly or can't be opened at all. This includes encrypted HP update files, Dell HDR and EXE files, some InsydeFlash FD files and so on. Enabling support for such files will require massive amount of reverse-engineering which is almost pointless because the updated image can be obtained from BIOS chip where it's already decrypted and unpacked. +* Intel Firmware Interface Table (FIT) editing is not supported right now. FIT contains pointers to various image components that must be loaded before executing the first CPU instruction from the BIOS chip. Those components include CPU microcode updates, binaries and settings used by BIOS Guard and Boot Guard technologies and some other stuff. More information on FIT can be obtained [here](https://edc.intel.com/content/www/us/en/design/products-and-solutions/software-and-services/firmware-and-bios/firmware-interface-table/firmware-interface-table/). +* Windows builds of `UEFIExtract` and `UEFIFind` might encouter an issue with folder paths being longer than 260 bytes (`MAX_PATH`) on some input files (see [issue #363](https://github.com/LongSoft/UEFITool/issues/363)). This is a [known Windows limitation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry), that can be fixed by enabling long paths support via Windows Registry and adding a manifest to the executable file that requires such support. `UEFIExtract` has the required manifest additions since version `A67`, and the required registry file is provided by Microsoft on the page linked above, but this workaround is only awailable starting with Windows 10 build 1067. + +## Bug repellents + +* [Coverity Scan](https://scan.coverity.com/projects/17209) - static analyzer for C, C++, C#, JavaScript, Ruby, or Python code. +* [SonarCloud](https://sonarcloud.io/project/overview?id=LongSoft_UEFITool) - cloud-based source code analysis service. + +## GUID Database + +Every new release includes an update to the database of known UEFI-related GUIDs build with help of [Linux Vendor Firmware Service](https://fwupd.org). + +You can download the up-to-date version of that database using [this link](https://fwupd.org/lvfs/shards/export/csv). diff --git a/README.rst b/README.rst deleted file mode 100644 index 6c48723..0000000 --- a/README.rst +++ /dev/null @@ -1,44 +0,0 @@ -UEFITool -======== -.. image:: https://raw.githubusercontent.com/LongSoft/UEFITool/master/uefitool.ico -.. image:: https://scan.coverity.com/projects/1812/badge.svg?flat=1 - :target: https://scan.coverity.com/projects/1812/ - -| -| UEFITool is a cross-platform C++/Qt program for parsing, extracting and modifying UEFI firmware images. -| It supports parsing of full BIOS images starting with the flash descriptor or any binary files containing UEFI volumes. -| Original development was started `here `_ at MDL forums as a cross-platform analog to `PhoenixTool `_'s structure mode with some additional features, but the program's engine was proven to be usefull for another projects like `UEFIPatch `_, `UBU `_ and `OZMTool `_. - -Installation ------------- - -| You can either use `pre-built binaries for Windows and OSX `_ or build a binary yourself. -| To build a binary you need a C++ compiler and an instance of Qt4/Qt5 library for it. -| Install both of them, get the sources, generate makefiles using qmake (*qmake UEFITool.pro*) and use your make command on that generated files (i.e. *nmake release*, *make release* and so on). - -Usage ------ - -| The program can be started directly without any arguments or supplied with a single argument - a path to the UEFI image file to open after start. -| -| The program window is divided into three panels: **Structure**, **Information** and **Messages**. -| Structure of the image is represented as a tree of elements with different names, types and subtypes. If you select an element, **Information** panel will show the available information about the selected element based on it's type and contents. -| **Messages** panel show all messages from the engine, including structure warnings and search results. Most of messages can be double-clicked to select the element that causes the message. -| -| You can open a menu on each tree element to see what operations are possible for the selected element. This can include various types of **Extract**, **Insert** and **Replace** operations, as well as **Remove** and **Rebuild**. -| **Extract** has two variants: **Extract as is** and **Extract body**. The difference is that **Extract as is** extracts the element with it's header (GUID, size, attributes and other structure-related information are located there), and **Extract body** extracts the element data only. -| **Replace** has the same two variants as **Extract** with the same meaning. -| **Insert** has the three different variants: **Insert before**, **Insert after** and **Insert into**, which is only available for UEFI volumes and encapsulation sections. -| **Remove** marks an element for removal on image reconstuction. -| **Rebuild** marks an element for rebuilding on image reconstruction. Normally, all elements that aren't marked for rebuild won't be changed at all and if you need to correct some structure error (i.e. invalid data checksum) you must mark an element for rebuild manually. If you change an element all it's parents up to the tree root will be marked for rebuild automatically. If UEFI volume is marked for rebuild all uncompressed PEI files in it will also be marked for rebuild because they must be rebased in the reconstructed image to maintain the executable-in-place constraint. -| -| There is also a search function available from the *File* menu, you can search all tree elements for a specified hexadecimal pattern (spaces are not counted, dot symbol (.) is used as placeholder for a single hex digit), a specified GUID (rules are the same as for hex except for spaces) and a specified text (either Unicode or ASCII, case sensitive or not). Search results will be added into **Messages** panel, if anything is found. -| -| After you've finished the modifications, you need to initiate image reconstruction using *Save image file* command from the *File* menu. If anything goes wrong on the reconstruction, an error will pop up, otherwise the program will prompt if you need to open the reconstructed file. Don't rush it, because reconstruction process can also generate some usefull messages, which will be lost if you open the reconstructed file immediatelly. - -Known issues ------------- -* Some images has non-standard calculation of base address of TE images, so the program can rebase them incorrectly after modifications. Will be solved ASAP. -* Some images may not work after modification because of no FIT table support implemented yet. It's on my high priority features list, so I hope it will be corrected soon. -* The program is meant to work with BIOS images, not some vendor-specific BIOS update files, that is why some of that update file either can\t be opened at all or return errors on reconstruction. If someone wants to write an unpacker for such crappy files - I will be glad to use it. -* AMI-specific features like NCBs, ROM_AREA structure and other things like that can't be implemented by me because of the NDA I have. diff --git a/Tiano/EfiTianoDecompress.c b/Tiano/EfiTianoDecompress.c deleted file mode 100644 index 156392c..0000000 --- a/Tiano/EfiTianoDecompress.c +++ /dev/null @@ -1,998 +0,0 @@ -/*++ EfiTianoDecompress.c - -Copyright (c) 2015, Nikolaj Schlej.

(LDRD/STRD/LDM/STM) + require 32-bit (WORD) alignment (by 32-bit ARM architecture). + So there is "Alignment fault exception", if data is not aligned for 32-bit. + +problem-2 : 32-bit kernels and arm64 kernels: + 32-bit linux kernels provide fixup for these "paired" instruction "Alignment fault exception". + So unaligned paired-access instructions work via exception handler in kernel in 32-bit linux. + + But some arm64 kernels do not handle these faults in 32-bit programs. + So we have unhandled exception for such instructions. + Probably some new arm64 kernels have fixed it, and unaligned + paired-access instructions work in new kernels? + +problem-3 : compiler for 32-bit arm: + Compilers use LDRD/STRD/LDM/STM for UInt64 accesses + and for another cases where two 32-bit accesses are fused + to one multi-access instruction. + So UInt64 variables must be aligned for 32-bit, and each + 32-bit access must be aligned for 32-bit, if we want to + avoid "Alignment fault" exception (handled or unhandled). + +problem-4 : performace: + Even if unaligned access is handled by kernel, it will be slow. + So if we allow unaligned access, we can get fast unaligned + single-access, and slow unaligned paired-access. + + We don't allow unaligned access on 32-bit arm, because compiler + genarates paired-access instructions that require 32-bit alignment, + and some arm64 kernels have no handler for these instructions. + Also unaligned paired-access instructions will be slow, if kernel handles them. +*/ + // it must be disabled: + // #define MY_CPU_LE_UNALIGN + #endif +#endif + +

being able to identify portions + * of the input text which are identical to earlier input (within a + * sliding window trailing behind the input currently being processed). + * + * The most straightforward technique turns out to be the fastest for + * most input files: try all possible matches and select the longest. + * The key feature of this algorithm is that insertions into the string + * dictionary are very simple and thus fast, and deletions are avoided + * completely. Insertions are performed at each input character, whereas + * string matches are performed only when the previous match ends. So it + * is preferable to spend more time in matches to allow very fast string + * insertions and avoid deletions. The matching algorithm for small + * strings is inspired from that of Rabin & Karp. A brute force approach + * is used to find longer strings when a small match has been found. + * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze + * (by Leonid Broukhis). + * A previous version of this file used a more sophisticated algorithm + * (by Fiala and Greene) which is guaranteed to run in linear amortized + * time, but has a larger average cost, uses more memory and is patented. + * However the F&G algorithm may be faster for some highly redundant + * files if the parameter max_chain_length (described below) is too large. + * + * ACKNOWLEDGEMENTS + * + * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and + * I found it in 'freeze' written by Leonid Broukhis. + * Thanks to many people for bug reports and testing. + * + * REFERENCES + * + * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". + * Available in http://tools.ietf.org/html/rfc1951 + * + * A description of the Rabin and Karp algorithm is given in the book + * "Algorithms" by R.

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

It may introduce + some output latency (reading input without producing any output) except when + forced to flush. + + The detailed semantics are as follows. deflate performs one or both of the + following actions: + + - Compress more input starting at next_in and update next_in and avail_in + accordingly. If not all input can be processed (because there is not + enough room in the output buffer), next_in and avail_in are updated and + processing will resume at this point for the next call of deflate(). + + - Generate more output starting at next_out and update next_out and avail_out + accordingly. This action is forced if the parameter flush is non zero. + Forcing flush frequently degrades the compression ratio, so this parameter + should be set only when necessary. Some output may be provided even if + flush is zero. + + Before the call of deflate(), the application should ensure that at least + one of the actions is possible, by providing more input and/or consuming more + output, and updating avail_in or avail_out accordingly; avail_out should + never be zero before the call. The application can consume the compressed + output when it wants, for example when the output buffer is full (avail_out + == 0), or after each call of deflate(). If deflate returns Z_OK and with + zero avail_out, it must be called again after making room in the output + buffer because there might be more output pending. See deflatePending(), + which can be used if desired to determine whether or not there is more output + in that case. + + Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to + decide how much data to accumulate before producing output, in order to + maximize compression. + + If the parameter flush is set to Z_SYNC_FLUSH, all pending output is + flushed to the output buffer and the output is aligned on a byte boundary, so + that the decompressor can get all input data available so far. (In + particular avail_in is zero after the call if enough output space has been + provided before the call.) Flushing may degrade compression for some + compression algorithms and so it should be used only when necessary. This + completes the current deflate block and follows it with an empty stored block + that is three bits plus filler bits to the next byte, followed by four bytes + (00 00 ff ff). + + If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the + output buffer, but the output is not aligned to a byte boundary. All of the + input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. + This completes the current deflate block and follows it with an empty fixed + codes block that is 10 bits long. This assures that enough bytes are output + in order for the decompressor to finish the block before the empty fixed + codes block. + + If flush is set to Z_BLOCK, a deflate block is completed and emitted, as + for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to + seven bits of the current block are held to be written as the next byte after + the next deflate block is completed. In this case, the decompressor may not + be provided enough bits at this point in order to complete decompression of + the data provided so far to the compressor. It may need to wait for the next + block to be emitted. This is for advanced applications that need to control + the emission of deflate blocks. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired. Using Z_FULL_FLUSH too often can seriously degrade + compression. + + If deflate returns with avail_out == 0, this function must be called again + with the same value of the flush parameter and more output space (updated + avail_out), until the flush is complete (deflate returns with non-zero + avail_out).

If not all input can be processed (because there is not + enough room in the output buffer), then next_in and avail_in are updated + accordingly, and processing will resume at this point for the next call of + inflate(). + + - Generate more output starting at next_out and update next_out and avail_out + accordingly. inflate() provides as much output as possible, until there is + no more input data or no more space in the output buffer (see below about + the flush parameter). + + Before the call of inflate(), the application should ensure that at least + one of the actions is possible, by providing more input and/or consuming more + output, and updating the next_* and avail_* values accordingly. If the + caller of inflate() does not provide both available input and available + output space, it is possible that there will be no progress made.

Z_SYNC_FLUSH requests that inflate() flush as much + output as possible to the output buffer. Z_BLOCK requests that inflate() + stop if and when it gets to the next deflate block boundary. When decoding + the zlib or gzip format, this will cause inflate() to return immediately + after the header and before the first block. When doing a raw inflate, + inflate() will go ahead and process the first block, and will return when it + gets to the end of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + To assist in this, on return inflate() always sets strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 if + inflate() is currently decoding the last block in the deflate stream, plus + 128 if inflate() returned immediately after decoding an end-of-block code or + decoding the complete header up to just before the first byte of the deflate + stream.

This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step (a + single call of inflate), the parameter flush should be set to Z_FINISH.

However it may be used to + inform inflate that a faster approach can be used for the single inflate() + call. Z_FINISH also informs inflate to not maintain a sliding window if the + stream completes, which reduces inflate's memory footprint. If the stream + does not complete, either because not all of the stream is provided or not + enough output space is provided, then a sliding window will be allocated and + inflate() can be called again to continue the operation as if Z_NO_FLUSH had + been used. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the effects of the flush parameter in this implementation are + on the return value of inflate() as noted below, when inflate() returns early + when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of + memory for a sliding window when Z_FINISH is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the Adler-32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the Adler-32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed Adler-32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data.
