a8bd8fff93 Make several changes to eliminate potential deadlock or recursive lock conditions, and add back rescan of multicast groups on network startup. 2014-10-14 16:38:27 -07:00
Adam Ierymenko
a94b0e6a43 Get rid of rescanMulticastGroups() in Network thread since this can deadlock... the fact that this can happen is probably bad design. 2014-10-14 15:58:03 -07:00
Adam Ierymenko
42d644a57e More fixes to legacy support, and to a potential issue on quit. 2014-10-14 12:37:35 -07:00
Adam Ierymenko
03dc823ad7 (1) Back off a little on default max multicast limit since 128 is pretty bandwidth heavy, (2) add a little to default multicast rate limit since new MC algo is fairerererer, (3) decided not to involve netconf masters in multicast so take that out of list of who gets LIKEs. 2014-10-10 12:55:06 -07:00
Adam Ierymenko
d5e0f7e3e4 Reorg multicast packet, and a whole bunch of refactoring around the pushing of certificates of membership. 2014-10-09 12:42:25 -07:00
Adam Ierymenko
2c8321be1f Pull logic to always send new multicasts to supernode since we need to do that differently, re-add support for active bridges, and remove some gratuitous use of std::set where not needed. 2014-10-04 13:15:02 -07:00

de4e29288d Fix for crazy Windows threading bug... repeatedly adding and removing a network now doesn't leave networks in limbo. 2014-08-21 17:49:05 -07:00
Adam Ierymenko
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.

77457cbff1 Windows compile fixes, compiler warning fix, unfreed memory fix in main.c (though it would not have mattered since program exits immediately after). 2014-08-07 19:08:41 -07:00

Adam Ierymenko
370dd6c4da Several things: 
(1) Add a bunch of tedious type casts to eliminate unnecessary compiler warnings on Windows X64 builds.

(2) Some EthernetTap work to integrate Windows custom IOCTL for multicast group lookup (not done quite yet).

(3) Dump some more info in selftest to make sure our Windows path lookup functions are returning sane results.

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.
