List of changes since previous release from 2018 is quite long: * Fix crc32.c to compile local functions only if used. * Check for cc masquerading as gcc or clang in configure. * Remove destructive aspects of make distclean. * Separate out address sanitizing from warnings in configure. * Eliminate use of ULL constants. * Add fallthrough comments for gcc. * Clean up minizip to reduce warnings for testing. * Fix unztell64() in minizip to work past 4GB. (Daniël Hörchner) * minizip warning fix if MAXU32 already defined. (gvollant) * Replace black/white with allow/block. (theresa-m) * Fix indentation in minizip's zip.c. * Improve portability of contrib/minizip. * Correct typo in blast.c. * Change macro name in inflate.c to avoid collision in VxWorks. * Clarify gz* function interfaces, referring to parameter names. * Fix error in comment on the polynomial representation of a byte. * Fix memory leak on error in gzlog.c. * Avoid adding empty gzip member after gzflush with Z_FINISH. * Explicitly note that the 32-bit check values are 32 bits. * Use ARM crc32 instructions if the ARM architecture has them. * Add use of the ARMv8 crc32 instructions when requested. * Correct comment in crc32.c. * Don't bother computing check value after successful inflateSync(). * Use atomic test and set, if available, for dynamic CRC tables. * Speed up software CRC-32 computation by a factor of 1.5 to 3. * Add crc32_combine_gen() and crc32_combine_op() for fast combines. * Add tables for crc32_combine(), to speed it up by a factor of 200. * Fix the zran.c example to work on a multiple-member gzip file. * Add gznorm.c example, which normalizes gzip files. * Show all the codes for the maximum tables size in enough.c. * Clarify that prefix codes are counted in enough.c. * Use inline function instead of macro for index in enough.c. * Clean up code style in enough.c, update version. * Use a macro for the printf format of big_t in enough.c. * Use a structure to make globals in enough.c evident. * Assure that the number of bits for deflatePrime() is valid. * Fix a bug that can crash deflate on some input when using Z_FIXED. * Correct the initialization requirements for deflateInit2(). * Emphasize the need to continue decompressing gzip members. * Add legal disclaimer to README. * Fix deflateEnd() to not report an error at start of raw deflate. * Remove old assembler code in which bugs have manifested. * Make the names in functions declarations identical to definitions. * Avoid an undefined behavior of memcpy() in _tr_stored_block(). * Avoid undefined behaviors of memcpy() in gz*printf(). * Avoid an undefined behavior of memcpy() in gzappend(). * Avoid the use of ptrdiff_t. * Handle case where inflateSync used when header never processed. * Don't compute check value for raw inflate if asked to validate. * Add address checking in clang to -w option of configure. * Return an error if the gzputs string length can't fit in an int. * Small speedup to inflate [psumbera]. * Update use of errno for newer Windows CE versions. * Avoid some conversion warnings in gzread.c and gzwrite.c. * Have Makefile return non-zero error code on test failure. * Avoid a conversion error in gzseek when off_t type too small. * Fix CLEAR_HASH macro to be usable as a single statement. * Fix bug when window full in deflate_stored(). * Limit hash table inserts after switch from stored deflate. * Permit a deflateParams() parameter change as soon as possible. * Cygwin does not have _wopen(), so do not create gzopen_w() there. Removed 006-fix-compressor-crash-on-certain-inputs.patch which was hotfix for CVE-2018-25032 and is now included in this release. This release is not available on @SF (yet?) so the sources are now pulled from GitHub. Fixes: CVE-2018-25032 Signed-off-by: Petr Štetiar <ynezz@true.cz>
OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
