Since commit 53b6783 hostapd is using the kernel api which includes the cbcmac-aes shash algorithm. The kernels implementation is a wrapper around the aes encryption algorithm, which encrypts block (16 bytes) by block. When the ltq-deu driver is present, it uses hardware aes, but every 16 byte encrypt requires setting the key. This is very inefficient and is a huge overhead. Since the cbcmac-aes is simply a hash that uses the cbc aes algorithm starting with an iv set to x'00' with an optional ecb aes encryption of a possible last incomplete block that is padded with the positional bytes of the last cbc encrypted block, this algorithm is now added to the driver. Most of the code is derived from md5-hmac and tailored for aes. Tested with the kernels crypto testmgr including extra tests against the kernels generic ccm module implementation. This patch also fixes the overallocation in the aes_ctx that is caused by using u32 instead of u8 for the aes keys. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de> |

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.
