hostapd: allow hostapd under ujail to communicate with hostapd_cli 
When procd-ujail is available, 1f78538387 runs hostapd as user
"network", with only limited additional capabilities (CAP_NET_ADMIN and
CAP_NET_RAW).

hostapd_cli (CONFIG_PACKAGE_hostapd-utils) communicates with hostapd
over a named UNIX-domain socket. hostapd_cli is responsible for creating
this socket at /tmp/wpa_ctrl_$pid_$counter. Since it typically runs as
root, this endpoint is normally created with uid root, gid root, mode
0755. As a result, hostapd running as uid network is able to receive
control messages sent through this interface, but is not able to respond
to them. If debug-level logging is enabled (CONFIG_WPA_MSG_MIN_PRIORITY
<= 2 at build, and log_level <= 2 in /etc/config/wireless wifi-device),
this message will appear from hostapd:

CTRL: sendto failed: Permission denied

As a fix, hostapd_cli should create the socket node in the filesystem
with uid network, gid network, mode 0770. This borrows the presently
Android-only strategy already in hostapd intended to solve the same
problem on Android.

If procd-ujail is not available and hostapd falls back to running as
root, it will still be able to read from and write to the socket even if
the node in the filesystem has been restricted to the network user and
group. This matches the logic in
package/network/services/hostapd/files/wpad.init, which sets the uid and
gid of /var/run/hostapd to network regardless of whether procd-ujail is
available.

As it appears that the "network" user and group are statically allocated
uid 101 and gid 101, respectively, per
package/base-files/files/etc/passwd and USERID in
package/network/services/hostapd/Makefile, this patch also uses a
constant 101 for the uid and gid.

OpenWrt logo

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

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to 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.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
