dee86e2448 But since we are now using middle 3 bits we can assign sane values for the cipher suite enum. 2014-10-02 11:13:53 -07:00

17da733f97 Gotta support old encrypted flag, move cipher spec to middle 3 bits... due to some shortsighted design early-on. In the future this can die once there are no old peers. 2014-10-02 11:08:59 -07:00

23836d4c11 Change "encrypted" flag to full cipher suite selector. Go ahead and reserve AES256-GCM which might be added in the future. 2014-10-02 10:54:34 -07:00

07f505971c Windows build fixes. 2014-01-17 17:09:59 -08:00
Adam Ierymenko
10df5dcf70 Fix several things:
(1) The changes to path learning in the two previous releases were poorly thought out,
and this version should remedy that by introducing PROBE. This is basically a kind of
ECHO request and is used to authenticate endpoints that are not learned via a valid
request/response pair. Thus we will still passively learn endpoints, but securely.

(2) Turns out there was a security oversight in _doHELLO() that could have permitted...
well... I'm not sure it was exploitable to do anything particularly interesting since
a bad identity would be discarded anyway, but fix it just the same.

f5d397e8c8 Pull in-band file transfer stuff. Toyed around with that idea, but it seems that updates for some platforms are big enough and there are enough reliability concerns that just using TCP/HTTP is safer and easier. 2013-12-04 10:45:15 -08:00

942cc0ca21 Certificate of membership works now... had to fix multicast propagation so COM is pushed with multicast, which makes tremendous sense in retrospect. 2013-10-25 14:51:55 -04:00

8c9b73f67b Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance. 2013-10-18 17:39:48 -04:00

ce14ba9004 Take the 0.6.0 opportunity to add flags to a few protocol verbs and do a bit more cleanup. Also fix it so certificates wont be accepted unless they are newer than existing ones. 2013-10-17 06:41:52 -04:00

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.

cfef114c31 Possible fix for issue #4 - segfault in ___removeIp helper function in EthernetTap on OSX -- I think the problem may have been that I was using set::erase(key) while also using an iterator, so now it uses erase(iterator). See if it happens again, cause I could not duplicate the issue. Possible minor difference in STL version. 2013-07-06 13:34:35 -04:00
