Tom Gundersen	0a1b6da821	sd-dhcp: message_init - only set secs in the client	2014-02-23 23:00:18 +01:00
Tom Gundersen	8fa2eeace7	sd-dhcp: don't reject packets with the 'wrong' source port ... The RFC does not specify that the packets from the DHCP server must come from the DHCP server port, only that that's where they should be sent. This fixes a problem when running networkd in VirtualBox. Thanks to Sébastien Luttringer for reporting the bug and very patiently testing various fixes.	2014-02-23 22:59:43 +01:00
Tom Gundersen	5266a81ea2	sd-dhcp: use FIONREAD to get correct size of incoming DHCP packet ... This avoids the problem of broken DHCP servers sending us too big packets that don't fit in our buffer.	2014-02-23 17:52:31 +01:00
Tom Gundersen	06b44be71d	sd-dhcp: equally verify udp and raw dhcp messages ... Also be more explicit about why packages are ignored.	2014-02-23 16:16:09 +01:00
Tom Gundersen	ac4f16ab4d	sd-dhcp: be more detailed about invalid headers ... This may be a common problem, so let's make it simpler to debug, at least for now.	2014-02-23 01:38:49 +01:00
Tom Gundersen	cf597f650a	sd-dhcp: split out packet handling from client	2014-02-11 16:24:23 +01:00
