With the latest client changes the internal event loop requires a handle
to wait on. Add a new function to (re)set the newly added transport event handle.
Up to this commit the client and server state machine handling used
different return values for state machine changes.
This is fixed with this commit:
* Use common enum return values
* Use common helper functions
The demand active state might be called when receiving data from the
client during initial connection phase or might be triggered server
side after sending a deactivate all pdu
The old code was looping with blindly checking for transport events, and then
sleep for 100 ms. It was doing that until the connection is established or
the timeout expired.
The new version polls the transport's events, potentially not having many 100 ms
waits.
* Fixed remdesk settings pointer
* Fixed sign warnings in display_write_monitor_layout_pdu
* Use freerdp_abort_connect_context and freerdp_shall_disconnect_context
* Added and updates settings
* info assert/dynamic timezone
* mcs assert/log/flags
* Fixed and added assertions for wStream
* Unified stream length checks
* Added new function to check for lenght and log
* Replace all usages with this new function
* Cleaned up PER, added parser logging
* Cleaned up BER, added parser logging
* log messages
* Modified Stream_CheckAndLogRequiredLengthEx
* Allow custom format and options
* Add Stream_CheckAndLogRequiredLengthExVa for prepared va_list
* Improved Stream_CheckAndLogRequiredLength
* Now have log level adjustable
* Added function equivalents for existing logger
* Added a backtrace in case of a failure is detected
* Fixed public API input checks
If freerdp_abort_connect is called, set FREERDP_ERROR_CONNECT_CANCELLED
This way freerdp_reconnect can distinguish between network issues and
user interaction and abort a retry attempt.
* Do length/capacity checks in every read/write/seek function
if WINPR_ASSERT is defined.
* Ensure s->pointer is valid, e.g. within s->buffer + s->capacity
(Stream_Rewind, Stream_Seek, ...)
* Add return values to Stream_Set* functions so inalid arguments
can be reported to the caller
* Deprecated problematic stream manipulation functions
(Stream_SetBuffer, Stream_SetPointer, Stream_SetCapacity)
* Ensure length/capacity functions never return a value larger
than the actual length/capacity
* Use freerdp_settings_* for shadow and sample server
* Added freerdp_peer_set_local_and_hostname
* Code cleanups and WINPR_ASSERT
* Code cleanups
* Use CHANNEL_NAME_LEN where appropriate
* Use temporary variables in loop instead of direct array access
(some client side channels and all server side channels still need to be
ported to new api)
server: build fix, do not disable threads for rfx encoder
cliprdr client channel: implemented support for DisableThreads option
looks like thread does not make sense at all for this channel
do not initialize disabled image codecs (respect settings)

changed "BOOL DisableThreads" to "UINT32 ThreadingFlags"
dropped unnecessary apu changes

TPKT header length and consumption of data was not consistently
checked. This adds checks after each packet processed and fixes
any inconsistencies found.
There are two loops polling the transport pdu receiver in non-blocking mode
when waiting for reaching CONNECTION_STATE_ACTIVE rdp state.
In case of an invalid pdu size in the tpkt header this leaded to an endless
loop, utilizing 100% of a cpu core.
Added a sleep and limited the max loop time to the tcp ack timout value.
This macro replaces the multiple instances where the current
error state is checked before setting an optional error state.

This new function allows better logging of call locations
for errors. Additionally added freerdp_set_error_log macro
to record function, file and line the error was set.

If no library can be loaded at runtime ignore H264 capabilities.
This allows a build with only OpenH264 support and dynamic loading
enabled to function when no openh264 library was detected.
With #4950 client side pointer implementation was made optional.
This addresses an issue that each client had to call
pointer_cache_register_callbacks on its own.
Since redirection sometimes happens with internal DNS names that
are resolved different by outside DNS it must be possible to override
the preferred redirection hint.
freerdp_reconnect might be called after a freerdp_connect failed due
to a TCP timeout waiting for user input.
In such cases we need to know if PostConect was already called and
do that if not.
Remember the callback state to avoid calling reerdp_channels_post_connect
before the corresponding client callback has benn called.
This might happen during redirection and reconnection.
In rdp_client_redirect or rdp_client_reconnect freerdp_channels_post_connect must
be called if the channels were connected previously.
This might not be the case, skip that call then.
Reconnect and redirect share the same code on disconnect.
Move that to a single function and export it as it may be required
to terminate the session properly before reconnect is called.
FreeRDP aborts if OpenSSL operates in FIPS mode and +fipsmode is not
manually specified. Let's prevent the abortion and enable the necessary
options in that case automatically.
This option will ensure that NLA is disabled(since NTLM uses weak crypto algorithms), FIPS
encryption is enabled, and ensure fips mode is enabled for openssl.
Selectively override specific uses of MD5/RC4 with new API calls specifically tailored to override FIPS.
Add comments on why overriding the use of these algorithms under FIPS is acceptable for the locations where overrides happen.
Remove check of server proprietary certificate which was already being ignore to avoid use of MD5.
Initialize winpr openssl earlier to ensure fips mode is set before starting using any crypto algorithms.
According to MS-RDPBCGR the server might send a password in the Redirection PDU
that then must be sent by the client to the server as password.
Since the field either contains a password string (unicode) or a binary cookie,
we try to convert the password from unicode and use it only if conversion
succeeds.
