Currently the VS build system targets VS2015, but
may also work for later versions (not tested).
To use:
- Download & install VS2015.
- Install WDK.
- Open a Developer Command Prompt.
- Run the msvc-build.bat script.
- Make WinDivertRecv() and WinDivertSend() arg
ordering match the Ex versions.
- Put the WinDivertHelperParsePacket() protocol
arg after the IP headers.
- WinDivert service handling is now protected by
a mutex.
- Debug the "uninstall" command for windivertctl.
It can now uninstall the WinDivert driver &
not leave the WinDivert service in a "pending"
state.
- Document WinDivert performance tips.
Adds a new SOCKET layer for monitoring socket
events, such as BIND, LISTEN, CONNECT,
and ACCEPT. These events occur before the
flow is established (and unlike the FLOW layer)
it is possible to block/drop SOCKET events.
Otherwise, this layer is very similar to the
FLOW layer, so the PID is available and injection
is not possible. This commit should be
considered to be a WIP.
Other changes:
- New socketdump.exe sample. Prints socket
events.
- Improve IPv6 address parsing.
- New helper functions:
* WinDivertHelperFormatIPv4Address
* WinDivertHelperFormatIPv6Address
- Fix REFLECT bugs.
- The network 5-tuple can now be accessed at
the NETWORK layer.
- Various cleanups.
Adds a new REFLECT layer for monitoring WinDivert
handles. This includes:
- three new REFLECT events: ESTABLISHED, OPEN and
CLOSE;
- modifying the ADDRESS for REFLECT data:
open time, process-id, layer, flags, and
priority of the opened handle; and
- allowing WinDivertRecv() to read a
representation of the opened filter.
This change also includes a new "object"
representation for WinDivert filter strings.
The API has been updated as follows:
- WinDivertHelperCompileFilter (replaces
CheckFilter) compiles filter strings into the
object form; and
- WinDivertHelperFormatFilter can "decompile" an
object back into a human-readable filter
string.
Other:
- New NO_INSTALL flag.
- New windivertctl.exe sample program.
