Installer and debug symbols available from https://npcap.org/#download
-
Fix a BSoD crash in
NPF_ReleaseOpenInstanceResourcesdue to miscounting of
number of open Loopback capture instances. Fixes #185. -
Fix corrupted and missing packets in Npcap 0.9992 and 0.9993 due to reusing a
data structure that already contained packet data. -
Fix a crash in
NPFInstall.exethat happened when trying to rebind Npcap to
the network stack as part of some installations. Reported by Microsoft App
Assure ISV Outreach Team. -
When multiple packets are indicated in a single
FilterReceiveNetBufferLists
callback, only get a single timestamp for all of them. Avoids extra calls to
KeQueryPerformanceCounter or KeQuerySystemTimePrecise which only ended up
measuring Npcap processing delay, not actual packet arrival time. -
Fix a potential NULL pointer deref issue in
Objpool.hmacros if an
allocation were to fail and return a NULL pointer. -
Fix parsing of
pnputil.exeoutput that resulted in Npcap drivers not being
cleared from the DriverStore before installing or upgrading. This led to
older drivers being preferred in some cases, such as installing an unsigned
driver in test mode. -
Move all capture- and injection-related initialization code out of
NPF_OpenAdapter, improving efficiency of operations like listing adapters
or performing OID requests without starting a full capture. -
Added SAL annotations to most driver functions to improve static analysis.
Found one issue related to using a NULL NDIS handle in an allocation
function, which is not supported on Windows 7. -
Allow driver to load even if there is a problem initializing loopback capture
or injection functions. The loopback capture device will simply be
unavailable in that case.
