Previously smartcard authentication was only supported with TLS
connections so the proxy forced that security mode.
Since we now have a working NLA smartcard auth implementation we can
remove that code and leave the correct configuration to the proxy user.
The cmd parameter (type int) has been logged using the %s format
specifier causing an access violation.
Fixed by using get_packet_type to convert cmd to a string.
* Fixed format strings to match arguments
Reviewed and replaced all %d specifiers to match proper type
* Added proxy dynamic channel command type to log messages.
During tests I sometimes received DATA_FIRST_PDUs that were not part of
a fragmented message but contained a complete PDU.
The documentation is not quite clear about if this is a possible
scenario or a protocol violation. However in the description of the Data
field it says:
If the sum of the DVC header size and the value specified by the Length
field is less than 1600 bytes, then the actual data length equals the
value specified by the Length field.
This hints that DATA_FIRST_PDU might also contain complete Data and does
not necessarily mean to be the first part of a fragmented PDU.
Only the least significant bit is valid in the unicode flag UINT32. Some
clients send garbage data in the other bits which caused the proxy to
drop the connection which is wrong.
* xfreerdp: fix typo in logs
* winpr: file appender, small code cleanup
* shadow-server: add an option for TLS secrets
This allows to dissect connections to the shadow server.
The shadow server was setting up the dynamic channel too quickly, leading
to unexpected packets during the negotiation (unexpected licence packet error
message on the client side). So let's starts dynamic channel once the activation is
done.
* add support for 64-bit big-endian encoding
* kerberos: drop reliance on gssapi and add user 2 user support
* Fix local variable declared in the middle of the function body
* kerberos: add ccache server option

This big patch fixes fragmentation handling in the dynamic channel. We used to
have a single state to handle fragmentation at the main dynamic channel level, but
in fact packets can be fragmented per sub channel. So we have to maintain a fragmentation
state per sub channel, this involve treating dynamic and static channels differentely
(so the size of the patch that has to implement state tracking per dynamic channels).
This adds a User, Domain and Password parameter in the Target section of the configuration
to specify and use a fixed backend user, domain or password (overriding the one
passed by the front user).
_align_XXX functions aren't widely available depending on the C runtime. That causes
problems with mingw where we can easily have some runtime mixes (which lead to mysterious
segfaults most of the time). This patch introduce winpr_aligned_XXX functions that will
either use the function available, or use an emulation layer.
