I've been working on bringing the radiotap headers to Linux so that we'll finally have a kernel-level multi-platform consistent way to get signal data on wireless cards.
Well, it'd also need to be brought to the Aironet driver on the BSDs as well, to complete that process. (It's listed in the subproject list for the FreeBSD Dingo project, but I haven't seen much work on it.)
Part of the argument which has arisen is about the 64byte static container that the radiotap headers define to put the variable length data in. It looks like libpcap as of 0.9.3 can handle variable headers correctly in filtering,
Well, it can handle Radiotap headers in filtering; it doesn't yet handle, for example, 3-address vs. 4-address 802.11 headers, or token ring headers with source routing fields.
so this is no longer needed... is that a correct assessment?
It should be, unless I screwed up somewhere when I added that support. - This is the tcpdump-workers list. Visit https://lists.sandelman.ca/ to unsubscribe.
