The beta2 of WinPcap 3.1 is available from today in the download section of
the WinPcap site.
WinPcap 3.1 beta2 is a minor update, that fixes a number of bugs that were
present in the first beta.
There's a new feature, too: under 2000/XP/2003 we have added a new fake
NdisWan adapter, useful to capture LCP/NCP PPP packet, for example. This
adapter is always listed (if you have enough privileges), even if you don't
have any PPP/VPN/... connection established. Please note that this feature
is experimental, and that we will be glad to hear comments from people that
use it.
CHANGELOG
=========
- Added some code to show a fake NdisWan adapter, useful to capture LCP/NCP
packets. This adapter is always listed on 2000/XP/2003 (if you have enough
privileges), even if you don't have any PPP/VPN/... connection
established.
- Added a check in the installer, so that the installation fails if you
don't have administrator privileges.
- Added a check so that NdisWan adapters (PPP, VPN, ...) are listed only if
you can capture from them.
- Added a new sample program, which gets the MAC address of an interface
using packet.dll
- Modified the access to the global list of adapters in packet.dll under
NT4/2000/XP/2003. Now packet.dll should be thread-safe.
- Bug fixing:
+ fixed some resource leaks in the remote capture daemon (rpcapd).
+ fixed a couple of resource leaks in packet.dll.
+ fixed some meaningless last error messages set by PacketOpenAdapter
(e.g. "The operation completed successfully").
+ fixed a shortcoming in pcap_findalldevs, by which the adapters where not
listed if they couldn't fit into a 8kB buffer.
+ fixed a memory leak in pcap_lookupdev.
+ fixed some bugs related to adapters listing:
* some adapters were not listed, especially if some registry keys are
messed up.
* in some situations the listing failed with the message "Attempt to
release a mutex not owned by caller"
* if PacketGetAdapterNames() failed, it returned the wrong number of
needed bytes for the input buffer.
+ fixed a buffer overrun in npf.sys that caused crashes (BSODs) when
there are too many adapters in the registry.
+ fixed a bug in npf.sys that caused blue screens (BSODs) when you try to
send "jumbo" packets, i.e. packets bigger than the maximum frame size
for the selected link type.
+ minor bug fixes.
