f5cbb45ab9 Increase sleep/wake detection threshold... might want to switch to using native interfaces to really detect this in the future since this is not 100% reliable. 2014-08-18 10:13:25 -04:00

f8d4611d15 (1) Tweak LAN locator beacon frequencies, (2) Windows virtual networks
now show up as *real* networks and prompt the user to set their
location and firewall status (public, private, home/work, etc.).

The hack used to achieve #2 should not be examined by children or those
suffering from epilepsy or heart conditions.

595b386afc Increase maximum packet fragments to make room for huge multicasts with certificates of membership tagged onto them. This likely will not actually increase the number of fragments in practice much, since these are then subsequently compressed. But the buffer needs to be allocated with room for them, otherwise these packets get dropped with a range_error exception internally. 2014-03-31 14:53:33 -07:00

fc18334dbb Version 0.4.3 (the real one): fix Gentoo ip config failures and crashes
This version fixes problems with locating the 'ip' command on Gentoo
and possibly other Linux systems, and a problem that could cause a
crash if EthernetTap was unable to locate one of the commands it
invokes to configure IP information on tap devices.

The code also now builds on Windows. It doesn't run yet, but it's a
step. Windows port is in full swing.

Finally, the multicast rate limit defaults were raised a little. More
testing is needed here, and real world measurments.

ef3e319c64 Several things:
(1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed.

(2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture.

(3) Add -fstack-protect to Makefile to bounds check stack variables.
