* New buffer API; the first installment of the conversion/replacementdjm2014-04-301-232/+100
| | | | | | | | | | | | of OpenSSH's internals to make them usable as a standalone library. This includes a set of wrappers to make it compatible with the existing buffer API so replacement can occur incrementally. With and ok markus@ Thanks also to Ben Hawkes, David Tomaschik, Ivan Fratric, Matthew Dempsky and Ron Bowes for a detailed review.

* avoid use of OpenSSL BIGNUM type and functions for KEX withdjm2014-01-121-1/+74
| | | | | | | Curve25519 by adding a buffer_put_bignum2_from_string() that stores a string using the bignum encoding rules. Will make it easier to build a reduced-feature OpenSSH without OpenSSL in the future; ok markus@

* Add buffer_get_cstring() and related functions that verify that thedjm2010-08-311-1/+34
| | | | | | | | | | | | | string extracted from the buffer contains no embedded \0 characters* This prevents random (possibly malicious) crap from being appended to strings where it would not be noticed if the string is used with a string(3) function. Use the new API in a few sensitive places. * actually, we allow a single one at the end of the string for now because we don't know how many deployed implementations get this wrong, but don't count on this to remain indefinitely.
