* kex: server fix for first_kex_packet_followsJon Simons2014-04-221-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Ensure to honor the 'first_kex_packet_follow' field when processing KEXINIT messages in the 'ssh_packet_kexinit' callback. Until now libssh would assume that this field is always unset (zero). But some clients may set this (dropbear at or beyond version 2013.57), and it needs to be included when computing the session ID. Also include logic for handling wrongly-guessed key exchange algorithms. Save whether a client's guess is wrong in a new field in the session struct: when set, the next KEX_DHINIT message to be processed will be ignored per RFC 4253, 7.1. While here, update both 'ssh_packet_kexinit' and 'make_sessionid' to use softabs with a 4 space indent level throughout, and also convert various error-checking to store intermediate values into an explicit 'rc'. Patch adjusted from original to ensure that client tests remain passing (ie 'torture_connect'): restrict the changes in 'ssh_packet_kexinit' only for the 'server_kex' case.

* pki crypto: expose new ssh_pki_key_ecdsa_name APIJon Simons2014-04-091-0/+2
| | | | | | | | | | | | | Enable retrieving the "ecdsa-sha2-nistpNNN" name of ECDSA keys with a new 'ssh_pki_key_ecdsa_name' API. This gives more information than the 'ssh_key_type_to_char' API, which yields "ssh-ecdsa" for ECDSA keys. The motivation is that this info is useful to have in a server context. The torture_pki unit test is updated to include the new API, and a few more passes are added to additionally test 384 and 521-bit keys.
