All, This is my first try at a patch and also my first attempt at parsing /etc/config files in OpenWRT. If I've goofed something up please let me know. The purpose of this change is to allow users to config radvd to run in unprivileged mode. Per the radvd man page:
radvd(8) - Linux man page http://linux.die.net/man/8/radvd -u username, --username username If specified, drops root privileges and changes user ID to username and group ID to the primary group of username. This is recommended for security reasons. You might also need to use -p to point to a file in a username -writable directory (e.g. /var/run/radvd/radvd.pid). This patch can parse three new fields in /etc/config/radvd, under "config radvd", specifically: option secure_mode 1 option username 'nobody' option group 'nogroup' I think the above is fairly self explanatory. When run with the "-u" option, radvd spawns two processes, one with root privileges for interface configuration purposes and another, unprivileged process, for everything else. With none of these options configured radvd will operate as it always has. Any suggestions and / or input would be appreciated. As I said, this is my first crack at working with OpenWRT so there's a possibility I did something incorrect. Thanks in advance, Adam
