Release notes:
new features:
- large dns record lookups via tcp fallback
- new getaddrinfo EAI_NODATA result to distinguish NODATA/NxDomain
- support for new RELR compressed format for relative relocations
- sysconf keys for querying signal stack size requirements
- real vfork on riscv64
performance:
- mallocng no longer uses MADV_FREE (high performance cost, little gain)
- vdso clock_gettime is supported once again on 32-bit arm
compatibility:
- gethostbyname family now distinguishes NO_DATA from HOST_NOT_FOUND
- res_send now works with caller-provided edns0 queries
- arpa/nameser.h RR types list is now up-to-date
- previously-missing POSIX confstr keys have been added
- mntent interfaces now accept missing fields
- alt signal stack, if any, is now used for internal signals
- the LFS64 macros are no longer exposed without _LARGEFILE64_SOURCE
- memmem (POSIX-future) is now exposed in default feature profile
- pthread_atfork now admits calls from an application-provided malloc
- debugger tracking of shared libraries now works on MIPS PIE binaries
- sendmsg now supports up to SCM_MAX_FD fds in SCM_RIGHTS messages
bugs fixed:
- gethostbyname[2]_r wrongly returned nonzero (error) on negative result
- parallel v4/v6 address queries could fail on query id collisions
- spurious getaddrinfo/AI_ADDRCONFIG failures due to errno clobbering
- dns search domains ending in dot (including lone dot) broke lookups
- ipv6 servers in resolv.conf broke lookups on systems with v6 disabled
- systems with bindv6only failed to query both v4 and v6 nameservers
- res_mkquery mishandled consecutive final dots in name
- res_send could malfunction for very small answer buffer sizes
- resolver dns backend accepted answers with wrong (A vs AAAA) RR type
- getservbyport_r returned junk or ENOENT (vs ERANGE) on buffer size errors
- dns result parsing of malformed responses could process uninitialized data
- freopen didn't reset stream orientation (byte/wide) & encoding rule
- fwprintf didn't print most fields on open_wmemstream FILEs
- wide printf %lc ignored field width
- wide printf erroneously processed %n after encoding errors
- use of wide printf %9$ argument slot overflowed undersized buffer
- swprintf malfunctioned on nul character in output
- strverscmp ordered digit sequences vs nondigits incorrectly
- timer_create/SIGEV_THREAD failure leaked the thread
- semaphores were subject to missed-wake under certain usage patterns
- several possible rare deadlocks with lock handling at thread exit
- several possible rare deadlocks with aio and multithreaded fork
- dynamic linker relro processing was broken on archs w/variable pagesize
- async cancellation could run cancellation handlers in invalid context
- pthread_detach was wrongly a cancellation point in rare race code path
- use-after-close/double-close errors in mq_notify error paths
- mq_notify event thread wrongly ran with signals unmasked
- wcs{,n}cmp, wmemcmp returned wrong results when difference overflowed
- accept4, pipe2, and dup3 handled unknown flags wrong in fallback cases
- CPU_SETSIZE macro had wrong unit
- select fallback for pre-time64 kernels truncated timeout (vs clamping)
arch-specific bugs fixed:
- x32 new socketcalls took fallback path due to pointer sign extension
- x32 wait4 didn't fill rusage structure (time64 regression)
- x32 semtimedop mismatched timespec ABI with kernel (time64 regression)
- sigaction signal mask was bogus on or1k, microblaze, mips, and riscv
- powerpc-sf longjmp asm clobbered value argument
- or1k poll function passed timeout to syscall in wrong form
Removed upstreamed:
- 800-mips_pie_debug.patch
Manually rebased:
- 600-nftw-support-common-gnu-extension.patch

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!
Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
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.

LuCI Web Interface: Modern and modular interface to control the device via a web browser.
-
OpenWrt Packages: Community repository of ported packages.
