Progressive codec was not honoring the threading flags in settings like does
remoteFX, so even when no multiple threads decoding was asked, progressive was
using multiple threads anyway. This patch fixes it.
The client tries to connect using RDSTLS only when it has received a
server redirection PDU with LB_PASSWORD_IS_ENCRYPTED flag.
The server exposes RDSTLS on negotiation if it has been configured on settings.
Then authenticates a client using configured credentials from settings:
RedirectionGuid, Username, Domain, Password.
Added helper functions to inform a user about current state of a client
in use:
* freerdp_client_warn_exeprimental warns about unstable clients
* freerdp_client_warn_deprecated warns about clients to be dropped
* extract the certificate from the redirection PDU
* if there is a certificate provided accept it if it matches the
redirection target certificate without further user checks
most protocol internal caches do not need to be exposed. this reduces
the public API and allows us to more easily improve/change this during a
release cycle
* Properly split certificate_store, certificate_data, certificate and
private key functions to files
* Prefix all functions with freerdp_ to have a unique name
* Update certificate store to use one file per host instead of
known_hosts2
* Merge CryptoCert and rdpCertificate
Currently the proxy's TLS fallback if an NLA connection attempt failed
is broken. There are two issues with the current code that this PR
fixes:
- freerdp_reconnect is used which requires an already established
connection to work correctly. This is not the case since the NLA
connectin attempt failed. This resulted in a seemingly working TLS
connection but i.e. channels where missing/not working.
- The fallback connection attempt just altered the NLA security setting
in the instance's settings. However these settings have been already
modified by the NLA connection attempt so we need to create a copy of
the original connection settings before doing the first connect.
The PR also introduces freerdp_reset_context which restores the initial
connection settings for the given instance.
* Remove duplications in rdpRsaKey, reuse rdpCertificate for public
components
* Move all private key and certificate code to certificate.c,
remove the tssk_* variables from gcc
* Handle update of client and server random keys in wrapping functions
* Simplify gcc_write_server_security_data, use certificate.c functions
to write the certificate data
* Refactor security_establish_keys, use the random values stored in
settings directly
