In my filter driver I have a need to compare SIDs (for equality) while
holding a spinlock (i.e. at DISPATCH level). My obvious choice was
RtlEqualSid(), but that can’t be used at DISPATCH level. Is there any
supported interface to do the comparison at DISPATCH level?
– Thanks, Rick
PSID is an opaque data type, so I wouldn’t try to cook up a custom
comparison routine. Can’t you do this around a fast mutex or eresource
instead of a spin lock?
