Permissions given in udev.permissions are not applied if no METHOD from udev.config is found. I've added do_kernelname() to scan for known permissions if we only use the default method. Simple support for wildcards is also added: #name:user:group:mode hdb*:2702:2702:0660 results in: drwxr-xr-x 2 root root 240 Nov 19 03:45 . drwxr-xr-x 23 root root 528 Nov 17 03:36 .. brw-r--r-- 1 root root 3, 0 Nov 19 03:45 hda brw-r--r-- 1 root root 3, 1 Nov 19 03:45 hda1 brw-r--r-- 1 root root 3, 2 Nov 19 03:45 hda2 brw-r--r-- 1 root root 3, 4 Nov 19 03:45 hda4 brw-r----- 1 kay kay 3, 64 Nov 19 03:45 hdb brw-r----- 1 kay kay 3, 65 Nov 19 03:45 hdb1 brw-r--r-- 1 root root 22, 0 Nov 19 03:45 hdc crw-r--r-- 1 root root 81, 0 Nov 19 03:34 webcam0
udev - a userspace implementation of devfs For more information on the design, and structure of this project, see the files in the docs/ directory. To use: - You must be running a 2.6 version of the Linux kernel. - Make sure sysfs is mounted. udev will figure out where sysfs is mounted, but the traditional place for it is at /sys. You can mount it by hand by running: mount -t sysfs none /sys - Make sure you have the latest version of the linux-hotplug scripts. They are available at linux-hotplug.sf.net or from your local kernel.org mirror at: kernel.org/pub/linux/utils/kernel/hotplug/ They are required in order for udev to work properly. If for some reason you do not install the hotplug scripts, you must tell the kernel to point the hotplug binary at wherever you install udev at. This can be done by: echo "/sbin/udev" > /proc/sys/kernel/hotplug - Build the project: make - Install the project: make install This will put the udev binary in /sbin, create the /udev and /etc/udev directories, and place the udev configuration files in /etc/udev. You will probably want to edit the namedev.* files to create custom naming rules. More info on how the config files are set up are contained in comments in the files, and is located in the documentation. - Add and remove devices from the system and marvel as nodes are created and removed in /udev/ based on the device types. - If you later get sick of it, uninstall it: make uninstall Things are still quite rough, and it's a bit beyond proof of concept code. Help is very much appreciated, see the TODO file for a list of things left to be done. If you want to build using klibc, use the Makefile.klibc file: - read the klibc/klibc/README file for how to set up the linux symlink properly. - make clean - make -f Makefile.klibc and marvel at the tiny binary you just created :) Any comment/questions/concerns please let me know. greg k-h greg@kroah.com
