Erik Lax	0c85e62af2	Detect remote DNS server does not support EDNS as per RFC 6891 (#244 ) EDNS retry should be based on FORMERR returned without an OPT RR record as per https://tools.ietf.org/html/rfc6891#section-7 rather than just treating any unexpected error condition as a reason to disable EDNS on the channel.

Fionn Fitzmaurice	6d6cd5daf6	Avoid buffer overflow in RC4 loop comparison (#336 ) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)	5 years ago
