This PR creates a new /gateway:type:arm transport.
It depends on CJSON
The arm transport is not a transport by itself but is responsible
for getting the websocket endpoint from a configuration url derived from
the configured gateway host in the rdpw file or cmdline
* factor out most websocket specific code parts into websocket.c
* create wst.c (Websocket Transport) as gateway transport implementation
* introduce GatewayUrl setting that holds the websocket url
* introduce GatewayHttpExtAuthBearer that holds the HTTP Bearer
* GatewayHttpExtAuthBearer can be used by both rdg and wst
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.
* 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
* 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
* 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
* Added missing definitions for RNS_UD_CS_SUPPORT_SKIP_CHANNELJOIN
and RNS_UD_SC_SKIP_CHANNELJOIN_SUPPORTED flags
* Updated stringification functions for these flags
* Implemented client and server EarlyCapabilityFlags filter for
these flags as FreeRDP currently does not implement them.
We no longer have a blocking polling loop in transport. Instead assume
there is more data after a packet was processed and let the transport
try again. If there is another packet ready, this repeats until only a
partly received (or no new data available) situation is reached.
* Add new settings for OrderSupportFlags, OrderSupportFlagsEx,
TerminalDescriptor and TextANSICodePage
* Add proper read/write routines for the new settings
* Add proper default values for the new settings
* Add new settings for previously ignored capability options
* Store raw capability data in settings for later use
* Add function to extract settings from raw capability data
* Split capability read/write from client/server logic (e.g. enforce
limits, ...)
* New defines for 10.8, 10.9, 10.10, 10.11 protocol versions
* New function returning a string representation of the protocol version
* Use 10.11 by default now
This new option /tls-secret-file:<file> allows to dump TLS secrets in a file with
the SSLKEYLOGFILE format. So this way you can setup the TLS dissector of wireshark
(Pre-Master-Secret log filename) and see the traffic in clear in wireshark.
It also add some more PFS ciphers to remove for netmon captures.
