2016-08-17llmnrd: Allow to bind to a specific network interfaceTobias Klauser1-3/+9
Add a command line option -i/--interface which allows to bind the llmnrd sockets to a specific interface. If used, requests are only answered on the specified interface. Example: llmnrd -i eth0 Closes #9 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-08-16llmnrd: Don't enumerate and store IPv6 addresses if IPv6 is disabledTobias Klauser1-1/+1
Currently IPv6 addresses are always enumerated via RTNL socket and then stored internally, even if llmnrd was started without the IPv6 command line option '-6'. Even though no queries on AF_INET6 sockets will be answered, this behavior might be confusing. Especially due to messages like: Added IPv6 address fe80::f0eb:aaff:feb3:ae58 on interface tap0 being logged. Explicitely disable IPv6 address enumeration on the RTNL socket to fix this behavior. Closes #8 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-08-02llmnrd: Use MAXHOSTNAMELEN for hostname buffer and zero-terminate stringTobias Klauser1-3/+4
Use MAXHOSTNAMELEN defined in sys/param.h to determine the size of the hostname buffer to allocate. Also make sure the string is properly zero-terminated in all cases, as in some cases it might be undefined whether a truncated string is properly terminated. Note: Also remove a TODO comment, as watching for hostname changes at runtime is outside the scope of llmnrd (also, avahi behaves the same). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
